A N type Al 0.2 Ga 0.8 As layer 14 is made to grow the entire surface including the layer 13', and the both ends of the film 14 are covered with concentric circular thin films 15 made of Si 3 N 4  etc. Then a P type region 16 is formed by means of diffusion process to the center of the layer 14 which includes the top of the tableland of the layer 13'; thus forming a PN junction 17 to the side face and another PN junction 17b to the bottom. On the film 15, a Si 3 N 4  film 15' that is wider than the film 15 is covered. Then a P type electrode 18 is installed to an opening on the area 16, while the center section of the substrate 11 is removed from the reverse side, and a N type electrode 19 is stuck to the remaining reverse side.

Title: Heat-cooking apparatus
Inventor: HIRAI KIYOSUMI
IPC: F24C1/04
Filed: 1984-05-02
Abstract: PURPOSE:To reduce the calory of a gas to a small value so as to lower the ignition sound and fire setting sound of the heat-cooking apparatus by exciting a fire controller and a solenoid coil before starting ignition. CONSTITUTION:Upon ignition and fire setting, since a solenoid coil moves to a position (b) of a seat 48 by a signal from a microcomputer, the gas has a low pressure, and it is possible to lowly suppress the fire setting sound. Therefore, even one electromagnetic valve can control the cooking. When the fire setting is completed, a flame rod senses it to turn off a switch. Hence, if it is assumed that the temperature of the interior of an oven is set at 300 deg.C of a slide volumeter on an display plate, a spring 47 at the connecting portion of a governor 44 is compressed. Further, a rod 50 of the governor 44 compresses a governor spring 51 so that the gas pressure becomes higher than the reference upon this occasion, the spring 51 contracts to reduce the gas flow quantity. Upon repeating burning and extinguishing of the burner, since fire force can be set at a low gas pressure by the action of a solenoid coil, the fire setting sound can be suppressed to a low value.
