Title: Optical recording thin film
Inventor: FUKUMA MASAHARU
IPC: C03C17/245
Filed: 1982-09-27
Abstract: PURPOSE:To cause optical change by irradiation of light ranging frm UV rays to visible light, and to enable optical reading of its change, and easy erasion of it by heating by laminating a rare earth element oxide and silver on a substrate or vapor depositing both at the same time. CONSTITUTION:In the case of vacuum deposition, plural heaters are installed and each are filled with a rate earth element oxide and silver, and said oxide is deposited to a substrate of quartz glas or the like in several hundreds - several thousands nm film thickness, and then, silver is deposited in several hundreds nm film thickness, or both of them are deposited at the same time to obtain an optical recording thin film. When the surface of the optical recording thin film or the rear side of the transparent substrate is exposed to intense light, such as laser light in the photosensitivity wavelength region, the optical property of the film at the exposed parts is changed, and the recording is thus carried out. It is advantageous to use a near IR light source to read the record. To erase the record, the recorded flm is heated for several min at 250-350 deg.C.

Abstract: PURPOSE:To obtain foaming refined SAKE(liquor) handleable at normal temperature, by adding fragrant component drains to pulverized unrefined SAKE at the end period of fermentation of unrefined SAKE just before it is packed into a container so that a fragrance after sterilization under heating is enriched, and foaming of carbonic acid gas is kept wall. CONSTITUTION:Unrefined SAKE at the end period of fermentation of unrefined SAKE is roughly ground, further pulverized, the pulverized unrefined SAKE is incorporated with fragrant component drains which are collected by cooling a fragrant component evolving with generation of carbonic acid gas during fermentation of unrefined SAKE, and packed into a container and sealed while live yeast molds are contained. Then, the unrefined SAKE is allowed to stand and fermented for several days while being kept at a given temperature (about 15-20 deg.C), so that a carbonic acid gas is naturally generated in the container. When pressure in the container reaches a given pressure (2.5-3.5kg/cm<2> at 20 deg.C), the fermentation is stopped, and it is heat-treated at 68 deg.C for about 5min and sterilized. Deterioration of fragrance can be prevented even by carrying out sterilization through heat treatment, and normal temperature handling is possible without using chilled circulation.

IPC: H01S5/00
Filed: 1988-07-08
Abstract: PURPOSE:To sharpen a light emitting spectrum of rare earth element ions and to use as a light emitting material by vapor growing rare earth element added III-V compound semiconductor at a temperature of a specific range when the semiconductor is epitaxially grown on a grown substrate. CONSTITUTION:A GaAs single-crystal substrate 2 is employed, and a rare earth element added III-V compound semiconductor layer 3 is formed thereon by a MOCVD method. Triethyl gallium as a material gas of group III element, arsine as material gas of group V element and trismethylcyclopentadienylerbium as material gas of rare earth elements are fed to a reaction tube. Its growing temperature is measured by a thermocouple connected to a growing temperature measuring fine tube 4.
