  • Patent number: 11426793
    Abstract: A method is provided to fabricate a high-power module. A non-touching needle is used to paste a slurry on a heat-dissipation substrate. The slurry comprises nano-silver particles and micron silver particles. The ratio of the two silver particles is 9:1˜1:1. The slurry is pasted on the substrate to be heated up to a temperature kept holding. An integrated chip (IC) is put above the substrate to form a combined piece. A hot presser processes thermocompression to the combined piece to form a thermal-interface-material (TIM) layer with the IC and the substrate. After heat treatment, the TIM contains more than 99 percent of pure silver with only a small amount of organic matter. No volatile organic compounds would be generated after a long term of use. No intermetallic compounds would be generated while the stability under high temperature is obtained. Consequently, embrittlement owing to procedure temperature is dismissed.

  • Publication number: 20220045572
    Abstract: The present invention provides a motor, comprising: a housing; a motor stator located in the housing; a motor output shaft located in the housing; and an exhaust device connected to the housing and configured to exhaust air from the interior of the housing. According to an implementation mode of the present invention, a turbine device is mounted on the motor output shaft; when the motor rotates, an inner cavity of the motor is evacuated to be in a negative pressure state; the higher the motor speed, the lower the air pressure inside the motor, the higher the vacuum degree, and the smaller the frictional resistance between a rotor and the air, so that the motor speed can be effectively increased and a rotor having a relatively large diameter can be used, thereby enhancing the low speed torque while increasing the power density of the motor and facilitating the design of a high power motor.

  • Patent number: 11173059
    Abstract: A tube stent includes a first tube body. The first tube body includes a first section, a second section, and a transition section located between the first section and the second section. One end of the transition section is connected to the first section, and the other end is connected to the second section. The shortening rate of the first section and the shortening rate of the second section are smaller than the shortening rate of the transition section. By using the tube stent, the pulsations of aortas are buffered by the transition section, so that vibration deformations of the tube stent are confined to the first section and the transition section, and accordingly the relative stability of the second section and branch blood vessels can be ensured, and the stimulations to walls of the branch blood vessels can be reduced.

  • Patent number: 10619108
    Abstract: The present disclosure relates to a method for a simulated moving bed to adsorb and separate polycyclic aromatic hydrocarbons. Zeolite, metal oxide and metal-modified materials are employed as adsorbent. Firstly, diesel oil flows through pre-treatment adsorbent to remove the trace amount of impurities. Secondly, the purified diesel oil flows through the simulated moving bed so that the PAHs can be separated from diesel oil. In this process, the valves are switched periodically, leading to the relative movement of adsorption beds. At the same time, desorbent is pumped into the equipment to wash out PAHs, achieving the continuous adsorption-regeneration operation. Thirdly, simple distillation is employed to separate desorbent from clean diesel oil and PAHs, respectively. Finally, the fractions of clean diesel oil and PAHs can be obtained, respectively. The separated desorbent can be recycled. The PAHs removal rate can reach to 90%.
