Abstract: PURPOSE:To facilitate the integration of various kinds of optical microelements and to obtain various kinds of optical thin film IC by forming a PLZT type thin film and a specified thin film on a substrate to provide a multilayered structure. CONSTITUTION:A PLZT [(Pb, La)(Zr, Ti)O3] type thin film 11 and an As-S, As- S-Ge or As-S-Se-Ge type thin film 12 are successively laminated on a substrate 13 made of sapphire, spinel, magnesia or the like to manufacture a substrate for an optical device. Since light 14 to be propagated is effectively propagated in the film 11, a significant electro-optical effect peculiar to the film 11 and an acousto- optical effect utilizing piezoelectric properties such as the diffraction of light due to a surface wave are attained at the same time. The propagation of light can be controlled by writing in the film 12 such as a thin As2-S3 film on the surface of the film 11 by irradiation with electron beams, so the integration of various kinds of optical microelements is facilitated, and various kinds of optical thin film IC can be obtd.

Title: Electrical sheltering structure for electric parts arranged in water tank
Inventor: HARAGA HISATO
IPC: A47K3/00
Filed: 1989-06-02
Abstract: PURPOSE:To prevent electricity propagation to the water in a tank by wrapping electric parts with a conductive material, and thereby allowing the current leaking at the electric parts to be fed back via the cover. CONSTITUTION:Nozzle motors M1 and a valve body position sensor 75 are wrapped with a cover 76, and conductive plating 77 is applied to the inner surface of this cover 76, and current is fed to a metal plate 78 for fitting of each nozzle motor M1. These metal plates 78 are put in electrical continuity with one another through a conductors 79. Even though water intrusion, etc., has caused continuity of the nozzle motors M1 and/or valve body position sensor 75 to the bathing hot water, the electricity is fed back via the plating 77 and metal plates 78, so that it will never propagate in the direction of the bathtub body 1. Because the metal plates 78 are put in mutual continuity to cause formation of a low-impedance circuitry between the metal plates 78, eventual continuity of any plurality of nozzle motors M1 with the bathtub lets the current flow through this circuitry, preventing from flowing inside the bathtub. Thus electric shocks are prevented.

Therefore, the workpiece 14 can be prevented from being dropped. Since the workpiece 14 is prevented from being dropped, the moving speed of the truck 10 can be increased, and therefore, the conveying efficiency is improved.
