  • Patent number: 11398447
    Abstract: A semiconductor device includes an insulating substrate formed by integrating a ceramic base plate and a cooling fin; a multiple of plate interconnection members; and a plurality of semiconductor elements. The one faces of the semiconductor elements are bonded to the ceramic base plate of the insulating substrate with a chip-bottom solder, and the other faces thereof are bonded to the plate-interconnection members with a chip-top solder so that plate interconnection members correspond respectively to the semiconductor elements. The chip-bottom solder and the chip-top solder both contain mainly Sn and 0.3-3 wt. % Ag and 0.5-1 wt. % Cu. This allows the semiconductor device to be reduced in size without impairing heat dissipation.

  • Publication number: 20180304111
    Abstract: A sprinkler head employing balls for a heat-sensitive disassembling unit is provided, in which the time period from when a fusible alloy starts to melt until when the sprinkler head is activated is shortened. A sprinkler head includes a frame having a stepped portion projecting inward. The stepped portion has an upper inclined surface provided at the inner-peripheral upper edge thereof and with which balls come into contact, and a guide part provided at the inner-peripheral lower edge thereof and that allows any of the balls that is displaced from the upper inclined surface to move downward from the stepped portion. When a fusible alloy melts, the ball displaced from the upper inclined surface moves along the guide part and is quickly released to the outside of the frame. Hence, the time period from when the fusible alloy starts to melt until when the sprinkler head is activated is shortened.

  • Patent number: 9536343
    Abstract: In a three-dimensional image generation apparatus, a CPU concatenates meshes of a plurality of objects which meet a predefined concatenation condition, and performs in advance vertex attribute transformation on the plurality of objects of which the meshes have been concatenated. The CPU regards as a single object, the plurality of objects on which the vertex attribute transformation has been performed, and transfers a rendering command, which instructs rendering of the plurality of objects regarded as the single object, to a GPU. The GPU renders, at a time, the plurality of objects that are regarded as the single object, upon receiving the rendering command from the CPU.
