component damage generally includes video card chip damage, graphics card BIOS damage, video memory damage, graphics card capacitor damage or damage to the field effect tube. For the failure of the graphics card components generally need to carefully measure the graphics card circuit in each signal to determine the damaged components, to find the damaged components, to replace it. 　　(4) video card overheating failure: Because the graphics chip in t

　　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

be very large. When the resistance between the anode (A) and the cathode (C) is measured, both positive and reverse resistance should be very large. 4. Polarity recognition of Bidirectional Thyristor Two-way thyristor has primary electrode 1, primary electrode 2 and control pole. If the resistance between two primary electrodes is measured with A multimeter R × 1k, the reading should be approximately infinite, the positive and reverse resistance readings between the control pole and any prima

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

, the cursor unresponsive, do not listen to command. The reasons for the failure and solutions are: 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

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

requires soldering with electric irons or connecting the broken circuit pins back to the good. Sensitivity variation 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: One, light-emitting tube or photosensitive components aging: Optical mouse core IC internal integration has a constant current circuit, wil

phenomenon. 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) video card component damage failure: The failure of the graphics components will usually cau

When such a sound is transmitted from the outer ear canal to the drum, its intensity can be increased by 10 times. (2) enhancement effect of eardrum and middle ear bone chain The middle ear includes the main structures such as Eardrum, eardrum, ossiclink, middle ear minor muscle, and throat tube. The relationship between the eardrum, ossiclink, And the egus windo

remaining low voltage pin is the collector C. Another method is to use HFE block to judge. After determining the base and tube of the transistor, the base of the transistor is inserted into the LO value measurement hole according to the base position and the tube type, the other two pins are inserted into any two of the remaining three measuring holes, observe the size of the data on the display, find the
