  • Publication number: 20190184667
    Abstract: The position adjusting indicator device for manual heat press machine, comprising a pedestal, and there is a fixed or sliding base plate on the upper plane pedestal, there assembles heating element on the upper plane of the base plate. The middle of the rear end of the pedestal connects to the rack, and on the middle of the rack installs the housing. A handle can be assembled on the near side of the housing; An arm can be assembled with position adjusting indicator device components below the handle. And the arm is installed on the heating element, one side of the arm is fixedly connected with the rack. The up and down of heating element is controlled by adjusting position indicator device in order to achieve accurate pressure. The heat press device utilizes manual position adjusting pressure to achieve accurate position and better transfer effect, which avoid the disadvantages that the traditional heat press machine can not accurately adjust the position and save adjusting position time.

  • Patent number: 8957502
    Abstract: A semiconductor device is disclosed that has enhanced its electric charge resistance. A first parallel p-n layer is disposed in an element activating part, and a second parallel p-n layer is disposed in an element peripheral edge part. An n? surface area is disposed between the second parallel p-n layer and a first principal face. Two or more p-type guard ring areas are disposed so as to be separate from each other on the first principal face side of the n? surface area. First field plate electrodes and second field plate electrodes are electrically connected to p-type guard ring areas. Second field plate electrodes cover the first field plate electrodes adjacent to each other so as to cover the first principal face between the first field plate electrodes through a second insulating film.

  • Patent number: 8748982
    Abstract: Semiconductor regions are alternately arranged in a parallel pn layer in which an n-type region and a p-type region are alternately arranged parallel to the main surface of a semiconductor substrate. Pitch between n drift region and p partition region of a second parallel pn layer in an edge termination region is two thirds of pitch between n drift region and p partition region of a first parallel pn layer in an active region. At boundaries between main SJ cells and fine SJ cells at four corners of the semiconductor substrate having rectangular shape in plan view, ends of two pitches of main SJ cells face the ends of three pitches of fine SJ cells. In this way, it is possible to reduce the influence of a process variation and thus reduce mutual diffusion between n drift region and p partition region of the fine SJ cell.
