What is a Hybrid PBX Phone System
What is a Hybrid PBX Phone System
A hybrid PBX combines existing legacy PBX equipment with VoIP. A PBX connects internal users to the outside world with a PRI or BRI, which has 24 channels. There are often many PRIs to connect hundreds of phones. In a hybrid PBX, these PRIs connect to a device—this is the Hybrid PBX itself—and the two devices connect to the outside world via both PSTN trunks and SIP credentials. The hybrid PBX also has many IP extensions to connect directly to IP phones in the office. On one side of the device, there are number of Ethernet and telephone jacks; on the other, there is usually a WAN (to the internet), a LAN (to the internal network), a console port, and LED lights to indicate which lines are active. Asterisk, and its many derivatives, is the most popular method of deploying hybrid PBX.
A hybrid PBX has many of the same great features you can expect from VoIP services, including call rules, auto-attendant, and hold queues. The hybrid PBX also has the capacity for virtual conference rooms, fax over IP, and videoconferences. The hybrid PBX also can do SIP trunking. The most important feature of the hybrid PBX is that if either the legacy PBX or the VoIP server isn’t working, it automatically switches over to the other network.
One of the biggest benefits to having a hybrid PBX is for remote offices and secondary locations. Calls from one office to the other go through the hybrid PBX, so there are no long-distance charges. If a location is temporary, such as an amusement park or construction site, you can use cordless phones to connect directly to the hybrid PBX instead of going through the building’s telephone lines.
One of the biggest benefits to having a hybrid PBX can also be its biggest drawback: cost. You have to buy and maintain an on-premise device. The largest hybrid PBXs are well over a thousand dollars. But, you can end up saving money in the long term by owning your own equipment, rather than having a third party host your PBX.

What is the difference between French Teppanyaki and Japanese Teppanyaki?
As we all know, the first thing that comes to mind when talking about teppanyaki is that it originated in Japan. Japanese teppanyaki is a rather high-end food in Japan, so its status is also very important, but teppanyaki originated only in Spain. , And then introduced to Japan. After 40 years of development, the teppanyaki culture was carried forward and turned into Japanese teppanyaki.
French teppanyaki is also similar. It is a combination of Chinese, Japanese and French teppanyaki cultures. It originated from Taiwan’s 30 years of development. It was originally called Taiwanese teppanyaki because the French style makes people imagine beautiful and romantic. In the French atmosphere, Taiwanese Teppanyaki is called French Teppanyaki.
French Teppanyaki
Of course, the ingredients used in French teppanyaki and Japanese teppanyaki are different. The biggest difference lies in the production process between the two. French teppanyaki is more romantic, which allows gourmets to feel its romantic mood. French-style teppanyaki is very romantic in terms of seasoning and sauce, and there is also a beautiful performance of the chef’s special teppanyaki table, which makes this romantic atmosphere to the extreme, and the atmosphere is to the extreme, so the food can also be full of a kind Romantic atmosphere.
Japanese-style teppanyaki is relatively simple, and the atmosphere is relatively simple. It pursues the taste of teppanyaki with the sauce. French-style teppanyaki is richer. Each dish is dedicated to a theme and takes a long time. French teppanyaki is also more particular in terms of ingredients and presentation, pursuing the original taste of the food.

High vacuum system with throttling
High vacuum system with throttling
The pressure range of sputtering and other plasma processes is higher than that of various high vacuum pumps. These pumps can be used in the range of 0.5 to 10 Pa by adding a throttle valve between the pump and the vacuum chamber. This kind of throttle valve with small flow conductivity allows the gas from the high pressure and strong vacuum chamber to flow into the pump, while keeping the pump inlet pressure below the maximum pump pressure or critical inlet pressure. The typical sputtering chamber with cathode diameter of 150 to 200 mm has a diameter of 500 mm and a height of 250 mm. The traditional pumping unit is equipped with a 6-inch diffusion pump, but there are also some similar low-temperature pump or turbine molecular pump. The maximum displacement of such a pump is 100 to 200 PA · L / s. The pump is larger and, although more expensive, it also removes gas faster.
The problem of residual gas in the sputtering system is much larger than that in the high vacuum evaporation system. On the one hand, the plasma desorption of impurities on the wall is increased; on the other hand, the conventional sputtering deposition rate is much lower than the typical evaporation rate. Even if the production rates of the two processes are in the same order of magnitude, the sputtering films are more likely to be exposed to the residual gas impurities than the films condensed by the evaporation source. Electron ion collision desorption is an effective way to release gas from the wall of vacuum chamber, which is even more effective than mild baking. In the plasma, the desorbed gases appear to exist in the atomic state, so they can easily react with the sputtered films.
