  • Publication number: 20190259628
    Abstract: A method includes maintaining a pressure in the process chamber at a threshold before and after a wafer is transferred into the process chamber and during the annealing process of the wafer. Not only the temperature fluctuation caused by the turbulent flow of the gas during the annealing process of the wafer can be avoided, but also the time for the temperature in the chamber to recover and stabilize can be shortened, thereby improving the equipment productivity.

  • Patent number: 10386270
    Abstract: The invention provides a method for simulating real impact test of vehicle wheels, and the method is implemented using a system as follows: the system includes a vehicle used in wheel simulating real impact test, a road surface, a high-frequency lighting facility, a standard obstacle block, a high-speed camera, and a traction motor and steel cable. The method for simulating real impact test of vehicle wheels of the invention has the advantages that: the need for testing various types of wheels using one set of equipment can be satisfied by using a general type collision trolley, thereby avoiding the use of a corresponding real vehicle for each type of wheels in the test. This greatly reduces the test cost, ensures that the test condition is similar to the real vehicle condition, and can well simulate the performance of a real vehicle when meeting an obstacle.

  • Patent number: 10381202
    Abstract: Embodiments of the invention provide a magnetron and a magnetron sputtering device, including an inner magnetic pole and an outer magnetic pole with opposite polarities. Both the inner magnetic pole and the outer magnetic pole comprise multiple spirals. The spirals of the outer magnetic pole surround the spirals of the inner magnetic pole, and a gap exists therebetween. In addition, the gap has different widths in different locations from a spiral center to an edge. Moreover, both the spirals of the outer magnetic pole and the spirals of the inner magnetic pole follow a polar equation: r=a?n+b(cos ?)m+c(tan ?)k+d, 0<=n<=2, 0<=m<=2, c=0 or k=0. Because the gap between the inner magnetic pole and the outer magnetic pole has the different widths in a spiral discrete direction, width sizes of the gap in the different locations can be changed to control magnetic field strength distribution in a plane, thus adjusting uniformity of a membrane thickness.
