Filed: 1983-03-23
Abstract: In a surface hardening process for metal parts by nitriding or carbonitriding, the parts to be treated are placed in a furnace and maintained at a temperature of between 490 DEG  C. and 750 DEG  C., in a nitrogen bearing atmosphere, such atmosphere formed by introducing into the furnace a gaseous mixture comprising in particular ammonia and an oxidizing gas for accelerating the catalytic dissociation of ammonia in contact with said parts. The oxidizing gas is nitrous oxide and the gaseous mixture contains about 0.1% to 10% by volume of nitrous oxide. The invention is well suited for the surface hardening of steel parts.

Title: Manufacture of semiconductor device
Inventor: SAITOU MANZOU
IPC: H01L21/318
Filed: 1983-03-22
Abstract: PURPOSE:To allow a high quality nitride film to grow without introduction of defect into a substrate by uniformly heating the both front and rear sides of substrate using hight irradiation heating method. CONSTITUTION:After implanting boron ions to a P type semiconductor substrate 21 as a channel stopper, said boron ion implanted region is selectively oxidized and thereby a thick field oxide film 22 is formed in the thickness of 1mum. An insulating film on the region to be thermally nitrided is removed and thereby the silicon substrate surface is exposed. Thereafter, the surface is thermally nitrided under the ambient containing ammonia within the light irradiation furnace and thereby thermal nitride film 23 is formed. After a polysilicon gate 24 is formed, arsenic ion is implanted and annealing is carried out in order to form the source and drain region 25. Next, the polysilicon surface is oxidized to a little extend and then a PSG (phosphor silicate glass) film 26 is formed by vapor growth method, a contact hole 27 is then bored therein and an aluminum electrode 28 is formed. In a field effect transistor or integrated circuit thus manufactured, a thermal nitride film formed by the light irradiation method is used for gate insulating film and therefore a film having less degree of fault density can be formed because a film is dense even when film is as thin as about 110Angstrom .

IPC: H01M10/60
Filed: 1982-03-25
Abstract: PURPOSE:To efficiently release heat generated in a battery to make possible use at high rate discharge and keep safety even in misuse such as short circuit by setting a metallic sealed hollow body, and filling liquid, and connecting electrically one electrode and an outer terminal with the hollow body. CONSTITUTION:When a positive terminal and a negative terminal are shorted, or a battery is discharged at large current, joule heat is generated inside the battery, and battery temperature is increased. Heat is released to outside in the outside of the battery, and transmitted to the side wall of a tube 2'' in the center portion. Pure water in the tube is heated and vaporize and heat is absorbed by temperature increase and heat of vaporization. Vapor is cooled by outside air in a cap 2', and liquefied to water, and heat of condensation is released at the same time. Heat generated in the battery is quickly released outside and overheating inside the battery is suppressed. Liquefied water in the cap 2' moves along inner wall of the tube 2'' and again vaporized by heat in the inside of the battery, and then liquefied. This cycle is repeated and water functions as heat transmission media.
