Title: Dry type gas meter
Inventor: YAMAMOTO YOSHIO
IPC: G01F3/22
Filed: 1981-10-12
Abstract: PURPOSE:To obtain a highly reliable dry type gas meter by providing the gas meter with an electromagnetic coil operating a detaining mechanism checking the rotational motion obtained by converting the reciprocating motion of a measuring film so as to be airtightly isolated from the body of the gas meter. CONSTITUTION:At a normal time, a permanent magnet 23 fitted to the other end of a detaining piece 22 is attracted by an electromagnetic device 24, so that the rotational motion of a crank board 17 based upon the reciprocating motion of a measuring film 11 is carried out without troubles because a pawl part 22' is located under the crank board 17 and gas is sent from a gas meter while being measured. If current having a polarity checking the attracting power of the permanent magnet 23 is supplied to an electromagnetic coil 26 even in a moment, the detaining piece 22 is rotated and a pawl 22' is projected up to the rotational height of the crank board 17 and abutted to an engaging part 17', so that rotation is stopped and the reciprocating motion of the measuring film 11 is also stopped to interrupt gas feeding. Since the electromagnetic device 24 and other equipment are accomodated in a mechanical room 29 covered with a case, a highly reliable dry type gas meter provided with an interrupting function is obtained.

Title: Stern fin to control stern eddy
Inventor: HANAWA TOMOO
IPC: B63H5/16
Filed: 1982-09-17
Abstract: PURPOSE:To improve the efficiency of propelling by providing a fin projected from a rib line along a potential streamline in the boundary layer of water stream for removing or reducing stern eddy to remove stenn vibration in the generating area of three-dimentional exfoliation. CONSTITUTION:Under an water line 2 of a stern 1, a fin 20 is provided along a potential streamline in the boundary layer. It is between an adhesion line 6 and an exfoliation line 7 for removing or reduction the stern eddy in the generating area of three-dimentional exfoliation. In this construction, the stern eddy is turned into a layer stream without changing the shape of a rib line, and since kinetic energy is reduced by the eddy in comparison with the increase of resistance due to the viscous flow of slow speed, the hull resistance is reduced to promote the propelling efficiency. Besides, the distribution of wake in the surface of a propeller is uniformed to reduce vibrations.

Title: Diagnostic test system for information processor
Inventor: TSUCHIYA YOSHIO
IPC: G06F11/22
Filed: 1989-06-26
Abstract: PURPOSE:To attain a diagnostic test system having high universal applicability without testing an emulator by providing a means which produces an external interruption within an information processor and simulates the input/output of the input/output data. CONSTITUTION:When an instruction is received for the diagnostic test of an external input/output control part 30, a main storage 40 decides an input/output data transfer address to the part 30 and produces an external interruption after the transfer of the input/output data. Then an arithmetic processor 10 simulates the input/output operation of the input/output data to the part 30. Thus it is possible to deal with a new external input/output device control part and an external input/output device with change of the simulation of the input/output operation without connection of the external input/output device connected to the part 30 for simulation of the input/output operation of the data or without connection of an emulator. Thus it is possible to attain a diag nostic test system having high universal applicability.

On the upper clad layer 2a shaven by etching, a substance (e.g. niello) 7 which absorbs light with an oscillation wavelength is vapor-deposited or a compound semiconductor (e.g. InGaAs) 8 is formed by epitaxial growth. The light trapped in the waveguide 1 cannot be trapped by the thin clad layer 2a and leaks at its upper part. The light is then absorbed by the light absorbing body (niello 7, InGaAs 8) positioned thereon.

Abstract: PURPOSE:To prevent grease from sticking to the terminal part of a stop circuit for improving reliability by providing a groove on the flange part of a sliding axis while providing a stop circuit and a warning circuit flatly in the shifted positions. CONSTITUTION:A circular groove 13a is provided on the upper surface of a flange part of a sliding axis 7. Consequently, the groove 13a can catch flowing- down grease between the inside of a throughhole 5 and the outer surface of an axis part 8 of the sliding axis 7.

Filed: 1990-06-25
Abstract: PURPOSE:To control the threshold voltage of a p-channel MOS capacitor so as not to increase by maintaining an n-well at a negative potential when the p-channel MOS capacitor for rectification is operated. CONSTITUTION:An n-well X1 follows the voltage decrease of a node P1 by capacitive coupling using a parasitic capacitance CS between the node P1. Therefore, the n-well X1 shifts from a level close to a GND level to a negative voltage level. Under such condition, a pMOS capacitor 24 becomes conductive and the level of an n-well Y1 on the opposite side is clamped to a ground voltage GND even being risen by the effects of the parasitic capacitance CS of a pMOS capacitor 14. A pMOS capacitor 23 is being cut since the gate voltage does not exceed a threshold voltage Vth. At such time, the n-well X1 is not supplied with the ground voltage GND through the pMOS capacitor 23 and the n-well X1 is maintained at the negative voltage.
