Title: Gas leak detector for gas supply pipe
Inventor: KENJO TSUNEO
IPC: F16K37/00
Filed: 1990-06-27
Abstract: PURPOSE:To detect fine leak of gas without trouble and stopping gas supply for a while by connecting a fine leak detector on the side of a gas supply pipe in gas supply devices of multiple dwelling houses. CONSTITUTION:A valve housing 20 is connected to the source side of a gas supply pipe 4, for example between a gas regulator 6 and gas meter 7 at the inlet and outlet ports 20a and 20b. On the down stream side of a nozzle 22 a float type valve elements 24, which are energized by a compressed coil spring 26, are opposed to each other. Directly below the nozzle 22 and at the gas outlet 20b, bypasses 28a and 28b are communicated to each other and are extended to both sides of a fine leak detector 30. In this case, when a certain household in an apartment house uses consumption devices and the gas consumption is increased, for example, the valve elements 24 are opened, and gas flows to both sides of the fine leak detector 30 and valve elements 24. When gas consumption is decreased at night or midnight, the valve elements close the nozzle 22, as a result, gas flows to the side of the fine leak detector 30.

Abstract: PURPOSE:To effectively stop a carriage mechanism with proper external force having little fluctuation by constituting a lock mechanism to suck a part of a mounting side of a driving coil via a through hole formed in a stopper. CONSTITUTION:When a power source is cut off during the working time, the carriage mechanism 6 is stopped with a head slider 3 positioned above a contact- start-stop zone 19 by a draft and gravity, etc. At this time, the mechanism 6 is brought into contact with a buffer member 10A. Under this condition, a self-hold type solenoid 13 is controlled via a lead wire 14 by a main package, and is fixed to the holding side.

Title: Information recording medium
Inventor: OKAWA HIDEKI
IPC: G11B7/24
Filed: 1985-07-30
Abstract: PURPOSE:To maintain the writing characteristic of the titled medium for a long period and to preserve the written information by forming one of recording films by dispersing semiconductor fine particles in a nondiffusible substance which is not diffused into the other recording film at ordinary temp. CONSTITUTION:The information recording medium is composed of a Ge-C thin film 12 coated on a substrate 11 as the first recording film and a Te-C thin film 13 coated on the film 12 as the second recording film. When the thin films 12 and 13 are laminate, a plasma-polymerized material blocks the diffusion of Ge and Te fine particles at ordinary temp. When a laser beam is irradiated on such a recording medium from the substrate 11 side, the films 12 and 13 are mixed, a single layer 15 having different reflectivity is formed and information is read by utilizing the difference in reflectivity. Besides, while a laser beam is not irradiated, the diffusion is blocked by the plasma-polymerized material, hence the shelf life of the recording medium is prolonged and the writing characteristic can be maintained for a long period.

Each valve of the jigs 4, 6, 6a is opened so as to reduce the pressure of the air inside of the space K, and while, the filling material is sucked into the space K for filling from the filling material supplying body.  Furthermore, after recognizing flow-in of the filling material into the transparent hose, the valves of the jigs 6, 6a are closed, and after the filling material is hardened, the jigs 4, 6, 6a are removed. Filling time is thereby remarkably shortened, and the whole of the peeling space can be filled with the filling material.
