Title: Fuel battery
Inventor: SAKAI KATSUNORI
IPC: H01M8/24
Filed: 1986-11-06
Abstract: PURPOSE:To improve reliability and performance of a fuel battery by increasing a cross-sectional area of fuel gas flow passage in a unit cell located at the lower part of layered stack. CONSTITUTION:The differential pressure of fuel gas fed to a fuel gas supply manifold 11 between outlet and inlet of a battery is large at the upper part but is small at the lower part of battery. By the arrangement that a layered group C 15 located at the lower part has a large cross-sectional area of fuel gas flow passage in a unit cell, the pressure loss is reduced and the fuel gas flows easily even if the differential pressure between outlet and inlet of the battery is small.

Title: Memory address conversion system
Inventor: JIYON AIKERU BOOKENHAAGEN
IPC: G11C29/00
Filed: 1988-10-20
Abstract: PURPOSE: To increase the storage locations without errors by a desired number by reconstituting a storage device according to the output of a storage inspection. CONSTITUTION: A CPU 1 inputs the sizes of the storage cards installed in a storage device 2 in a storage constitution register 3. In order to determine whether these cards have the storage without errors or not, the storage device 2 is inspected by the operating system of the CPU 1. When the cards without errors are discriminated by the physical addresses in the storage device, the operating system loads the physical addresses in a card discrimination register 4 from the lowermost location. The loadings are continued till the physical addresses of all the cards without errors are stored. Thus, the addresses are designated in accordance with the logical addresses of a desired storage location and the physical addresses corresponding to the actual storage locations of data can be generated.

Title: Portless type master cylinder device
Inventor: NOMURA YOSHIHISA
IPC: B60T11/16
Filed: 1986-11-05
Abstract: PURPOSE:To reduce an unavailable stroke of a piston as well as to aim at improvement in responsiveness, by installing a flow limiting device in an interconnecting passage between an inlet valve and a booster chamber, in the case of a vehicle brake master cylinder device or the like. CONSTITUTION:A push rod 49 makes piston members 3 and 4 go to the left against springs 7 and 8 by pedal operation, and when a piston cup 43 passages through a port 21, a first booster chamber 14 is intercepted from a reservoir 20 and thereby its pressure goes up. And, a rod 34 goes away from a stopper 23, a valve element 30 takes a valve seat part 32 by dint of a spring 33, and a second booster chamber 15 is intercepted from a reservoir port 24, thus its pressure goes up. During this while, the booster chamber 15 is interconnected to a reservoir interconnecting chamber 17, a fluid flows after being throttle by a throttle hole 28, and owing to this throttle effect, there is no difference between a dynamic stroke and static stroke of the piston and, what is more, a sudden pressure rise at time of valve closing of the valve element 30 or an inlet valve is avoided. Thus, an unavailable stroke of the piston is reduced, and responsiveness is improved.

Title: Abnormal information reporting system for computer system for control
Inventor: KON EIJI
IPC: G06F15/16
Filed: 1991-10-11
Abstract: PURPOSE:To standardize the reporting function of abnormal information at a remote CPU by setting the code corresponding data of an abnormal device and transmitting the abnormal information from the remote CPU to a host CPU. CONSTITUTION:In the case of activating the remote CPU and connecting the remote CPU from the host CPU, first of all, a connection request 1 is executed from the host CPU to the remote CPU to be connected. This connecting request includes the code corresponding data of the abnormal device to be used by the objective remote CPU, and the remote CPU sets 2 the information to its own internal data. Afterwards, the completion of connection is reported to the host CPU as a connecting answer 3. Thus, since the code corresponding data of the abnormal device are set so that the host CPU can recognize the connected remote CPU and afterwards the abnormal information is transmitted by the set code corresponding data, it is enough only to prepare one standardized corresponding data.

Abstract: PURPOSE:To obtain a compact two-axis linear encoder by providing the first and second diffracting grids with slits on two focal lines generated by astigmatic difference, and separately measuring the interference of the diffracted light. CONSTITUTION:When the laser light 2 oscillated by a semiconductor laser 1 is collected by a lens 3, the first focal line F1 is generated at the position of the distance S1 from the lens 3, then the second focal line F2 is generated at the position of the distance S2 from the lens 3. The focal lines F1, F2 are perpendicular to the main light 4 of the laser light 2 and perpendicular to each other. The distance (S2-S1) between the focal lines F1, F2 is the astigmatic differ ence of the semiconductor laser 1. The laser 1 generating the astigmatic differ ence is used as a light source in a two-axis linear encoder with this constitution, an X-diffracting grid 5 and a Y-diffracting grid 6 are arranged on the focal lines F1, F2 respectively, and the reflected diffracted light from each diffracting grid can be separately detected.

Title: Digital magnetic recording and reproducing device
Inventor: HIGUCHI SHIGEMITSU
IPC: G11B15/467
Filed: 1988-10-21
Abstract: PURPOSE:To maintain the continuity of tracking position and to improve reproduced image quality by accurately tracking a track where recording has been performed with the aid of a recording head at the time of reproducing and keeping such a state even in a recording state. CONSTITUTION:At the time of reproducing, a control CTL signal recorded on a control track is amplified by a reproducing amplifier 33 and separated to a CTL separation circuit 36. Since a reproduced CTL signal is inputted in a phase comparison circuit 30, a tape travels in synchronism with an input video signal. As a result, a cylinder rotates and the tape travels in synchronism with the video signal, then the head scans the track which is set. A division circuit 38 is reset with an output from the circuit 36 or an output from a variable delay circuit 29. Even if the action of a servo system is switched from reproducing to recording, a capstan rotates as well as at the time of reproducing and the continuity of the tracking position can be maintained by resetting the circuit 38. Thus, the reproduced image quality can be improved.
