IPC: E03D9/08
Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To provide a washing device having indications legible and readable by a toilet seat sitter, prolong life of liquid crystal and, at the same time, to provide the washing device having a non-contact operating section capable of scarcely being touched on the surface of a switch with the sitter's fingertip.

Patent JP-H03127892-A (JP)
Title: Semiconductor laser
Inventor: WATANABE HITOSHI
IPC: H01S5/042
Filed: 1989-10-13
Abstract: PURPOSE:To make possible an analog modulation having the good linearity of optical output-current characteristics by a method wherein a prescribed DC current, which is determined from the resistance radio, and a modulation current superposed on the DC current are independently injected in each of a plurality of the electrodes of a semiconductor laser element with a plurality of the electrodes formed in isolation in the direction of a resonator. CONSTITUTION:Electrodes are isolated into an electrode 2 on the side of the front surface of a laser resonator and an electrode 3 on the side of the rear surface of the resonator. As a DC bias current 5 is injected in each of the electrodes through a potentiometer 4, the current injection ratio is determined from the resistance ratio of the potentiometer 4. Accordingly, the current injection ratio is changed so as to correct the unevenness of a gain and a nonlinearity due to a leakage current can be corrected. On the other hand, a modulation signal is superposed on each DC bias current in the front surface and the rear surface and a modulated optical output waveform depends on the linearily of light output-current characteristics. Therefore, when the current injection ratio is determined in such a way that the linearily becomes the best, the distortion of the waveform can be minimized. Thereby, the linearity of the output of a laser is improved and distortion-free analog modulation becomes possible.

Title: Fluid compressor
Inventor: HIRAYAMA TAKUYA
IPC: F04C18/107
Filed: 1991-10-16
Abstract: PURPOSE:To prevent application of an excessive load on each spiral blade in a fluid compressor embodied in the spiral blade system by furnishing an opening/closing valve which is facing a plurality of working chambers partitioned by the blades and releases the pressure from a working chamber on the high pressure side toward a working chamber on the low pressure side. CONSTITUTION:When current is fed to a motor-driven element 9 for rotating a cylinder 17 constructed in a single piece with a rotor 15, a rotary body 21 is turned through an Oldham ring 23. Because this rotary body 21 makes eccentric rotation, a relative velocity is generated between its peripheral surface and the bore of the cylinder 17 facing the same 21 to cause its revolving relative to the cylinder 17. As a result, the fluid sent into the working chamber 35 on the suction side is compressed while fed one bit by bit to the working chamber 35 on the discharge end side. In this type of compressor, an opening/closing valve 43 is formed at the cylinder 17 in such a way as facing the working chamber 35 on the high pressure side and is operated so that it opens, when a large amount of fluid is confined in the working chamber 35 to put the inside thereof in the overcompressed state, and closes when this overcompressed state goes out.
