IPC: G11B7/135
Filed: 1987-10-26
Abstract: PURPOSE:To attain high speed recording and reproduction by splitting a projected light of a semiconductor laser into plural beams in a waveguide path, and using an optical switch so as to control the intensity of each beam, thereby stabilizing the optical output. CONSTITUTION:The semiconductor laser 1 is subject to high speed modulation and the control voltage of optical switches 4a-4c is changed synchronously with the modulation signal and the optical path is shared with optical projecting ends 5a-5d. Thus, high speed signal recording is attained. Moreover, the laser 1 is driven at a constant output and the control voltage of optical switches 4a-4c is controlled so as to make the projected luminous intensity of the light after passing through the optical switches 4a-4c equal to each other and signals are reproduced in parallel simultaneously so as to make the projected luminous intensity of the optical projecting ends 5a-5d equal to each other.

Title: Silver material for ornament
Inventor: TAKIGUCHI FUJIMATSU
IPC: C22C5/06
Filed: 1985-11-29
Abstract: PURPOSE:To improve a silver material for an ornament by dispersing uniformly and finely a specified amount of cadmium oxide and manganese oxide in silver so as to produce the silver material. CONSTITUTION:The composition of this silver material for an ornament consists of 85-99.5wt% silver and 0.5-15wt% cadmium oxide and manganese oxide. The silver material is produced by powder metallurgical processing and the oxides of cadmium and manganese dispersed uniformly and finely in silver are converted into a grain refiner by heat treatment such as annealing or brazing. An oxide film is not formed by the heat treatment. Since the hardness of the silver material can be increased, a lustrous ornament hard to scratch can be produced. The resulting ornament has no irregularity in color and causes no defective brazing.
