Clarinet Lingerie beautiful woman's careful choice

Before I was very interested in sales and operations, each time shopping to the display of goods, sales promotion methods are carefully observed. Through this post additional training, I systematically understand the laws and regulations of the display Yingzili beauty , how to determine consumer groups, timely control of sales, daily inventory, keep abreast of the latest price adjustment of your company, through the back office computer order, check Display and other work.

英姿丽人

Knowing the heroic underwear brand is purely casual, wanted to find information on the Web site, inadvertently entered the official website of the British-style beauty lingerie brand. After an overview, I was interested in it. Your business model showed me the business opportunity. Then I systematically reviewed the entire contents of the company's website and searched the web for any relevant information. After consulting and communicating with manager Li of Development Department, I decided to visit some places. To the company by Chen warm reception, and took me to do a careful inspection training, but also patiently answered all my questions. At that time, my feeling was: this business can do it! In this way, my Fascist beauty underwear brand franchise opened in November 2011, because never involved in the apparel industry, I think the first three months do not hold the purpose of making money, but did not expect that from the opening Turnover on the first day was beyond my expectations, the end of the account, but also profitable. At present, my second branch is being renovated, and now I recall, I am very grateful to the development department manager Li's patient communication, without your sincere contact, I will not know with the British beauty underwear brand; thanks also to the customer service staff Careful teaching, without your tireless, I will not deeply recognize the value of sales; more thanks to the company a sound marketing model, because of you, let me be more and more confident!

The Inevitability of Driving Lines Instead of Angle Lines

As a kind of commonly used power supply equipment, the trolley wire has many types. In the past, it used more angle iron trolley wire, and now it seems that this dominant position has been replaced by trolley wire. So what exactly is the difference between these two types of trolley wires?

Starting from the previous angle rails, it is also a kind of power supply equipment, but its main power supply material is iron; that is, the angle iron trolley wire is made of iron to conduct electricity.

The traffic trolley line is different from its conductor material is copper or aluminum alloy, after the comparison can clearly be seen that the performance of iron is far inferior to the aluminum alloy conductor or copper conductor, which is also the angle iron trolley line is touched by the trolley One of the reasons for the replacement of the line.

In addition, there is a very bad problem with the angle iron slip line, that is, when it is used for a long time, the surface of its iron conductor is prone to rust, and if it is used continuously, it will cause the surface of the conductor to be easily sparked and cause safety accidents.

The disadvantages of the angle iron trolley line are not limited to these. After testing, its resistivity is relatively large, and its conductivity is not very good. It is totally inconsistent with the national energy saving and emission reduction standards. This is also the reason why it is gradually eliminated by the market.

It should be noted that the surface of the traffic trolley line is completely enclosed by a safety jacket. Even if it is in its joint position, a joint protection sleeve is used to fully ensure that the human body does not touch any conductive portion of the trolley line, ensuring the user. The use of security.

Moreover, the trolley line has the advantages of easy installation, long service life, easy maintenance, and good electrical conductivity. It is precisely because of this that it is recommended to choose the trolley line when selecting the trolley line. Because it is not only a strong guarantee for safe production, but also from a long-term point of view, but also help reduce the maintenance غير مجاز مي باشدts of enterprises, how the national energy-saving emission reduction standards.

MC PCB

MC PCB--Metal Core Printed Circuit Boards


MC PCB means metal core printed circuit boards. why use metal,not FR4/CEM-1 or others? All is to get high thermal conductivity. The most MC PCB is Aluminum PCB, Aluminum has good heat transfer and dissipation ability, but also cheaper than copper based PCB.Many customers asked a quote for MC PCB but without the thermal requirements.If you know the thermal conductivity is the most most important thing for MC PCB,then 

you will know why the price is so difference. Normal thermal is from 0.8-2.00 W/m.k,and higher can up to 8.0 W/m.k,even more if you need ,but ,are you sure ? When we quote to you ,we have to ask you the thermal conductivity,it is not only about غير مجاز مي باشدt but your product.Many factories used low thermal ,can you use the boards?


MC PCB uses in LED lights,Industrial power equipment,Cars,Power,etc. Bergquist is the top quality metal core material but top غير مجاز مي باشدt as well. 

Thermal Conductive Board (TCB), or Insulated Metal Substrate (IMS), provides the advantages of high thermal conductivity, reliability and solder heat endurance. The TCB substrate is a sandwich structure, which includes layers of conductor, insulator and metal base.Traditionally, this insulator is made of epoxy, epoxy filled glass fiber, polyimide, or other dielectric materials. However, these kinds of insulators could not meet the requirement in high-power electronic devices. The heat generated by these devices will accumulate, and

the life time and reliability of the end product will decrease.

Visit bergquist to get more information about high thermal.

PTTC (Polytronics) is another top quality but much cheaper than Bergquist in the word ,it is made in TaiWan .visit PTTC.

Varjo prototype head resolution is 70 times that of existing VR heads

Varjo founder and CEO Urho Konttori said: "We believe that by speeding up the human eye solution as much as possible, everyone can experience in VR and AR terminals." Earlier this year, Nvidia's general manager of VR strategy Jason Paul estimates that a VR device that has an eye-catching resolution (about 220 million pixels) will take at least 20 years. Despite this, Varjo still claims that its technology is higher than Other technology companies.

Varjo head prototype

Varjo refitted an Oculus Rift and projected the image through an OLED microdisplay onto a glass plate on an Oculus lens. It is said that its resolution is 70 times that of Oculus Rift.

This prototype is a proof-of-concept demo. Since the microdisplay is persistent compared to the low-persistence display of the Rift, the edges are a little jittery in the transition from one image to another.

However, even with such restrictions, the demo gives you a very realistic feel for VR and AR. You can open files and browsers on a virtual Windows 7 desktop.

The prototype video provided by this VR company from Finland shows how this technology works with AR. Through perspective, people can have multiple "displays" when working in the office, home or on the plane. For example, another example of a video presentation shows that someone has manipulated a home model floating in front of it, such as moving furniture.

Varjo wants to solve the limitations of current technology

Konttori said: "The problem with today's VR and AR is that, first of all, they are essentially low resolution. We are talking about a 1% human eye resolution. The optical perspective system has a narrow vision. Everything you create in AR It's very awkward and artificial. It's not that the consumer wants the end result. If you're a professional who wants to display the product in mixed reality, then it needs to be accurately represented, not as a hologram.”

The company is targeting professional markets and plans to release virtual and augmented reality head-ups that are compatible with the SteamVR system. Varjo thinks it can use software and hardware to render 70-megapixel resolution to where you actually see it, not just in the center of the screen. Microdisplays can be physically moved, using rotation rendering just to reduce quality, and thus reduce GPU consumption. ”

Varjo believes that all pixels in the image will not exceed a 4K computer monitor, so today it can be run on current desktop and gaming laptops.

Varjo's current development schedule is to have its own prototype of head-mounted displays by the end of this year and to distribute hundreds of test hardware to partners. After collecting feedback and further optimization, the final headline should be listed before the end of 2018.

The difference between banana and banana

Banana is the most common fruit in life and it is a nutrient for fruit. However, bananas, which are shaped like bananas, often appear in fruit supermarkets. So what are the differences between these two seemingly identical fruits? What is the difference between these two types of fruit nutrition?

Bananas are sickle-shaped while bananas are straight; bananas are overall slender, bananas are slightly thicker at opposite ends, and bananas are shorter than bananas. The number of banana ribs depends on how big the sepals are before the development of the banana fruit and how many female flowers are contained in the sepals, regardless of the variety. The taste of plantain is with acidity, less water content, and toughness, but the nutritional difference between the two is not great.

Bananas and bananas belong to the Musaceae family and are similar in shape, color, and taste.” From the appearance, there are few banana ribs, long round bodies, short stems, and greenish blue color when immature, golden yellow after ripening, flesh It is yellowish-white and cross-sectionally nearly circular, while plantain is longer, thicker, more ribbed than banana, slightly larger at one end, slightly smaller at the other end, longer pedicel, yellowish-yellow skin of plantain, white-fleshed pulp, and oblate cross-section. In terms of taste, the bananas are sweet and sweet, while the banana pulp is slick, but it has a bit of sour aftertaste.

"Baban and bananas have little difference in nutritional value. They all belong to high-potassium foods and are rich in magnesium. Modern medicine has confirmed that potassium can maintain normal blood pressure and heart rate, prevent blood pressure from rising and muscle spasms, while magnesium has Eliminating the effects of fatigue, and that the sugar in bananas can be quickly converted to gluغير مجاز مي باشدe and absorbed immediately by the body, which is a fast source of energy, which is why many athletes like to eat bananas during the game.” In addition, from the nutrition From the point of view, bananas are warmer and contain more abundant dietary fiber and a large amount of water-soluble plant fibers. Therefore, they have the effect of laxativeness. Therefore, bananas do not cause constipation and bananas are more cool. Therefore, banana is more suitable for people with cold stomach and the elderly.

Foxconn Retires Music to New Stops Foundry LeTV

OFweek smart home network July 2 news, the reporter was informed that Foxconn affiliate Shenzhen Guan Ding has withdrew from LeTV to the new shareholders.

LeTV Zhixin is a holding subsidiary of LeTV, the listed platform of LeTV. It mainly hosts LeTV's smart TV business. LeTV Super TV was initially positioned as "double performance, half price". Based on the غير مجاز مي باشدt and even lower than the غير مجاز مي باشدt pricing model, LeTV Super TV soon became the "star player" in the color TV industry, and its market share rapidly expanded. According to the data, LeTV Super TVs sold about 300,000 units in 2013. By 2015, this figure has grown to 3 million units, and in 2016, it has reached the mainstream market with nearly 6 million units.

Based on the rapid expansion of LeTV, according to the resolution of the Board of Directors disclosed by LeTV.com on April 2, 2013, Shenzhen Guanding caused new investment to LeTV, and after the completion of the capital increase, Shenzhen Guanding took shares to 20% of the shares. This is the first time that Shenzhen Guanding appeared in the information disclosure of LeTV and LeTV New. The company is regarded as an affiliate of Foxconn. It is reported that LeTV has also signed an exclusive agreement with Foxconn. According to the agreement, Chairman Guo Jianming of Foxconn could no longer manufacture smart TVs for other Internet companies in Mainland China.

However, although LeTV’s rapid expansion has captured a large number of users, it has also caused LeTV a large financial gap. Levision's 2016 financial report showed that LeTV's operating revenue in 2016 was 21.9 billion yuan, a year-on-year increase of 68.64%; net profit attributable to shareholders of listed companies was down 3.19% year-on-year, which was the first time in eight years that profits declined. According to LeTV, the early stage super TVs mainly used high-level configuration, high performance, and quick acquisition of users to subvert the price, which caused the company's operating profit to decrease year-on-year.

As LeTV continued to be exposed to the financial crisis, Shenzhen Guanding was no longer in Lexus' new shareholder list since 2016. On December 21, 2015, LeTV.com referred to Shenzhen Guanding for the last time in “Jindu Law Firm’s Legal Opinion on Major Asset Purchase”. Since then, Shenzhen Guanding has not been seen in the open information disclosure of LeTV.

According to data from Ove Cloud Network, from January to April 2017, the number of LeTVs shipped by Foxconn was only 6,600, 3,200, 7,200, and 4,500. Dong Min, vice president of Ove Cloud Network, revealed that Foxconn currently has LeTV shipping, which may be the previous inventory.
