The invention relates to the technical field of semiconductor manufacturing, in particular to a through-silicon via process. The traditional three-dimensional wafer integration is completed by combining part of the second metal layer contained in the first BEOL dielectric layer with the third metal layer contained in the second BEOL dielectric layer, which greatly reduces the wafer performance while maintaining the same wafer performance. The volume of the wafer; at the same time, the part of the first metal layer contained in the first BEOL dielectric layer is not connected to any circuit, which overcomes the long-time secondary etching of the traditional process when charged particles bombard the metal in the first BEOL dielectric layer for a long time, resulting in the first wafer A large amount of charge accumulates in the metal, thereby destroying the defects of the semiconductor device in the first BEOL dielectric layer.

In the invention, alternating-direct current is converted into high-frequency alternating current by utilizing the skin effect, so that the ice-coated circuit generates more heat; anti-icing and deicing is carried out through the heat generated by the ice-coated circuit;and deicing frequency is selected in intelligent grade according to change of meteorological conditions, without affecting power transmission and supply, so as to settle circuit ice coating with minimal energy consumption, and thus not only anti-icing but also deicing can be achieved. The intelligent anti-icing deicing system has simple structure and strong implementation, and can be widely applied to high-voltage transmission lines in areas with frequent snow disasters.

The invention relates to an infrared scanning vehicle separator having automatic heating function, is mainly composed of a pair of a transmitter and a receiver which are arranged at opposite positions and comprises a housing arranged inside a protective covering; the front end of the housing fixes an optic window of heating glass by a sealing bar; the transmitter or receiver consisting of same number of infrared transmitting tubes or receiving tubes is fixed in the middle of the housing; the invention is characterized in that the lower surface of the optic window of heating glass is tightly stuck to a temperature switch, a transmitter or receiver control circuit and drive circuit connected with the temperature switch are installed in the middle of the housing, and the transmitter is communicated with the receiver by synchronous communication lines. The invention has the beneficial effects that the control circuit and drive circuit can be automatically started to heat the vehicle separator heating glasses under bad weather (rain, snow and fog) and the heating of heating glass is controlled by software in pulse control manner, thereby avoiding damages caused by long-term electrifying of heating glass. The window of heating glass on the protective covering is removed, thereby reducing attenuation for infrared transmitted lights.

The invention discloses an electronic cylinder provided with a valve seat frame and a push pin frame, all electromagnetic valve plates for fixing electromagnetic valves are arranged in the valve seat frame, the push pin frame is positioned below the valve seat frame and constructed by a stair descending plate and a push pin frame, the stair descending plate is provided with plural rows of push pin baffle plates, and the push pin frame and the restoring plate are integrated as a whole. Relative to the push pins, the valve seat frame can move to and fro in the horizontal direction and the vertical direction, and the push pin frame can move to and fro in the horizontal direction. Each electromagnetic valve is provided with two armature pins, porose or aporate situation is shaped by whether the armature pins cover the push pin baffle plate through pores, and the work is done. The invention replaces the restoring coils or permanent magnet with the mechanical restoring mode, thus, on the one hand, eliminating residual magnetism and resolving the problem of electromagnetic valve damage caused by easy breakage of the connecting wires of the working coils; on the other hand, resolving the problem of likely tremble of the hanging push pins under the combined action of the push pin frame and the push pin baffle plate after adopting the integral push pin structure, to enhance the adaptability of the push pins and the transverse pins.

The invention discloses a hydraulic control reducer with a neutral position for a drive motor of an electric vehicle, belonging to a power transmission system of an electric vehicle. The reducer and a motor are integrated into a whole, the shaft of the motor and the input shaft of the reducer are connected with each other at the front end of the motor, and a driving pinion on the input shaft of the reducer is in slip connection with the input shaft of the reducer through a spline; when the vehicle quickly moves under a non-traction working condition, the vehicle is in a two-wheel drive state, and at this time, the front axle is positioned in high gear and the rear axle is in an off-gear state; if the rear axle does not have the off-gear function, the drive motor can be subject to overspeed rotation which may cause damage to the motor. The invention has the advantage of compact structure, overcomes the defects in the quick movement of the vehicle under a non-traction condition and improves the efficiency of the transmission system of the electric vehicle.
