  • Patent number: 8742432
    Abstract: The invention provides a metal substrate and a light source device ensuring that a semiconductor chip working as a light source can be firmly joined by using a metal joining material, such that heat generated in the mounted semiconductor chip can be efficiently dissipated through a metal plate. The metal substrate includes a heat dissipating metal plate made of a metal except for Au, an insulating resin-made white film stacked on a part of the heat dissipating metal plate, and a light source mounting surface-forming layer stacked on another part of the heat dissipating metal plate. The metal substrate is such that the light source mounting surface-forming layer is a metal layer directly contacting the heat dissipating metal plate, and the light source mounting surface is a surface of an Au layer which is the outermost layer of the light source mounting surface-forming layer.

  • Patent number: 8363395
    Abstract: The release mechanism includes a guide body adapted to support a guide wall of the electronic device unit, and a locking mechanism adapted to lock the electronic device unit supported on the guide body. The locking mechanism includes an elastic piece projecting in cantilever fashion from an end of the guide body, an operating projection that projects from the elastic piece, and an engaging protrusion that protrudes from the elastic piece and that is adapted to intrude into a screw hole in the electronic device unit to thereby restrict sliding of the electronic device unit. The operating projection is formed with larger size than the engaging protrusion so that under conditions of induced flexure of the elastic piece the engaging protrusion disengages from the screw hole, and during sliding of the electronic device unit does not contact the guide wall.
