IPC: H01L33/30
Filed: 1987-03-04
Abstract: PURPOSE:To obtain an LED which shows excellent LED characteristics even for high current density by making a structure which has a current pouring region and a current non-pouring region by providing a stripe groove for current constriction in a region at the side of a light emitting edge and a region where a current blocking layer is left in the other region. CONSTITUTION:In an edge emission type light emitting diode which constricts an operating current by removing a current blocking layer 2 formed on a semiconductor substrate 1 in a stripe state, a current pouring region is restricted by only partially removing the current blocking layer 2 in a stripe state and by leaving the current blocking layer in the other region. For example, the n-type InP current blocking layer 2 is grown on the P-type InP substrate 1 and then, a stripe groove 7' 5 mum wide and 150 mum long equivalent to 1/2 element length is formed by selective etching by using the mask of a photo resist film formed on the n-type InP blocking layer 2. An P-type InP clad layer 3, a P-type InGaAsP active layer 4, an n-type InP clad layer 5 and an n-type InGaAsP cap layer 6 are consecutively grown on the groove 7' by liquid growth.

Filed: 1988-03-04
Abstract: PURPOSE:To easily heat rice balls or food stuffs within a vessel whenever desired by providing a space between a heat generating source and the internal surface of a mainbody and the external surface of the vessel. CONSTITUTION:A space 20 is formed between a heat-generating source 17 due to an exothermic chemical reaction, the internal surface 9 of the main body 3 and also the external surface 14 of a vessel 10. Therefore, the air within the space 20 is heated by the heat generating source 17 and the heated air conducts the heat to a metal vessel 10 with a large periphery area of a trapezoidal cone to heat the metal vessel 10. And also the heat is insulated. As a result, rice balls 22b and curried food 22a in the vessel 10, 11 are heated under a uniform thermal distribution and as the exothermal temperature of the heat- generating source 17 is not so high as in a direct heating system, foodstuffs inside the metal vessel 10, rice balls 22b or carried food 22a for instance, is slowly heated. Furthermore, as the exothermal time of the chemical reaction lasts long, heating or heat-insulating is kept for a long time.
