Title: Reflector for stove
Inventor: FUKUDA AKIO
IPC: F24C15/22
Filed: 1983-08-12
Abstract: PURPOSE:To improve far infrared ray radiation which is very effective as radiation type heating, by forming a film containing a metallic oxide having specific optical radiation properties on the surface of a metallic base. CONSTITUTION:The titled reflector consists of a film containing a metallic oxide, in relation to optical radiation properties of which emissivity is less than 0.4-0.5 on the side wherein short wave length is less than 4-5mum and the emissivity is more than 0.85-0.90 on the side wherein long wave length is more than 4-5mum in a temperature range of 200-400 deg.C, and a metallic base. A reflector forms a coating layer having high emissivity in an infrared sphere of more than 4-5mum. Radiation, therefore, whose peak is deviated on a long wave length side, is obtained. Infrared radiation, therefore, is obtained at its high efficiency, through effect of which mild warmth can be obtained. Although resistance to heat of the film becomes problem awaiting solution as an average temperature of the reflector becomes about 300 deg.C, deterioration of the film through heat can be prevented by making use of NiC and SiC polymer of heat resisting paint as a binding agent.

Title: Preparation method of semiconductor laser
Inventor: NAMISAKI HIROBUMI
IPC: H01L21/304
Filed: 1979-11-15
Abstract: PURPOSE:To accurately arrange a resonator length and to obtain a good cleavage plane by a method wherein a broken line type etching groove is formed in crossing a band like operational area and in avoiding a part of this band like area, and a  crystal is cleaved along this groove. CONSTITUTION:A V groove 10 is formed on a main plane wherein a stripe electrode of a wafer 1 is formed. At this time, this groove 10 is formed in a broken line  type crossing the electrode 2 positioned at the upper part of a band like operational  area 4 and avoiding the peripheral area of the electrode 2. When a cleavage is performed along the groove 10 of the wafer 1 like this, even if the direction of the  groove 10 is slightly out of a crystal azimuth, a step difference occurs only a lower  part of the groove 10 and does not occur in an area 4 contributing to a laser oscillation. And since the width of a stripe is ordinarily 20mum or less, if the groove 10 is separated with a spacing of approximately 50mum, the influence of a step difference  does not appear in the operational area. Whereas, the width of an ordinary element  is approximately 300mum, as a result, even if there is no groove 10 of approximately  50mum, there occurs no fault for cleavage.
