The MoS tube name comes from the English name Metal (metal), OXID (oxide), semiconductor (semiconductor), is a field-effect transistor, or a semiconductor called a metal insulator. Usually the FET (field effect tube) is generally used as a thin layer of silica as the insulator under the gate, so the usual MOS tube size is smaller than the ordinary bipolar trans
sampling time of the X-ray machine. These requirements can be achieved for general large and medium-sized X-ray machines.
2. The super pulse image (SPI) mode is 6 ~ The rate of 30 frames is used for X-ray Pulse imaging, and then the image is reduced repeatedly at a frame-by-frame high speed, which features high frequency and narrow pulse width, as shown in Figure 5-26. The X-ray exposure pulse is consistent with the camera field synchronization. The effective time of the exposure signal should
1, usually the DC power input anti-reverse protection circuit is to use the unidirectional conductivity of the diode to achieve anti-reverse protection. As shown in 1:This method of connection is simple and reliable, but the power dissipation effect is very large when the large current is input. To the input current rating of 2A, such as the use of Onsemi fast recovery diode mur3020pt, the nominal tube pressure drop of 0.7V, then the power consumption
Several problems should be noticed in the connection of optical cable.
1. Note the depth of the knife when opening the optical cable. The key to open the outer sheath of optical cable is to master the depth of the cutting tool, otherwise it is easy to break the fiber. In the actual operation, should rotate the sheath cutting knife, while observing the incision, if you can see the white polyester belt, you should stop the knife, remove the cutting knife. This step is a skilled process and requir

1. Overview of three types of non-isolated DC-DC topologies
1.1Buck type converter
The buck converter topology is shown in Figure 2.2 and the buck Converter is also known as a buck-type power supply topology. When the switching tube s is on, the diode VD negative voltage is higher than the positive reverse cutoff, at which time the current is fed through the inductance L to the capacitance and load, while the inductance L stores the energy. When the

1 light-emitting Tube or photosensitive element aging: The core IC of the optical mouse has a constant current circuit, the working current of the luminous tube is constant in about 50mA, the high grade mouse generally uses the intermittent sampling technology, the current that sends out is intermittent cond
this calculation, as a resonant cavity, the optimal resonance frequency is around Hz. When such a sound is transmitted from the outer ear canal to the drum, its intensity can be increased by 10 times.

Sensitivity variation is a common fault of optical mouse, specific performance for mobile mouse, the cursor unresponsive, do not listen to command. The reasons for the failure and solutions are:

Graphics compatibility failure generally occurs in the computer just installed or after the upgrade, more common in the motherboard and video card incompatible or motherboard slots and Kakin fingers can not be fully contacted. Graphics compatibility failure is commonly used to detect the substitution method, the general use of the replacement of the video card to troubleshoot problems.

3. Documents and data
This is mainly the document data stored by software such as pages, Numbers and imovie. After having the icloud drive, this kind of manuscript data is no longer only serves as the data backup in the application, but the independent file facilitates the editing and the use. Of course, this use can be implemented across the platform real-time editing, real-time synchronization.
