  • Publication number: 20200132132
    Abstract: An electric vehicle transmission method includes the steps of: detecting a gear-shift command; judging if the gear-shift command is in conflict, if it is in conflict, then it returns back to the step of detecting the gear-shift command while if it is not in conflict, then proceeds to the next step; proceeding to a synchronized position, a dispelling fork drives a synchronizer to make the synchronizer move from the original gear position to a synchronized position, and the dispelling fork does not move within a synchronized time; and proceeding to a target position, the dispelling fork drives the synchronizer again to make the synchronizer move to the target gear position.

  • Publication number: 20200072384
    Abstract: A diaphragm valve structure having application in diaphragm valves made completely from fluororesin at an operating temperature of 200° C. The diaphragm valve uses a heat separation method that consists of a heat transfer limiting structure and a heat dissipating structure, ensuring rigidity of the gas cylinder structure. The heat transfer limiting structure uses lattice-shaped ribbed plates with horizontal openings, wherein the lattice-shaped ribbed plates and a minimum diameter area of an annular portion are all provided with heat transfer section thickness. The heat dissipating structure consists of a multilayered structure for a preferred external natural cooling, and further using a coolant gas ensuring that the peripheral portion of the diaphragm and gas-tight sealing components on the valve shaft are sufficiently cooled.

  • Patent number: 10353262
    Abstract: The present invention discloses a method for fabricating an electrochromic device, which adopts the vacuum cathodic arc-plasma deposition to comprise five layers with an ionic conduction layer (electrolyte) in contact with an electrochromic (EC) layer and an ion storage (complementary) layer, all sandwiched between two transparent conducting layers sequentially on a substrate. The method owns superior deposition efficiency and the fabricated thin film structures have higher crystalline homogeneity. In addition, thanks to the nanometer pores in the thin film structures, the electric capacity as well as the ion mobility are greater. Consequently, the reaction efficiency for bleaching or coloring is enhanced.
