Title: Semiconductor layer with modulator and its manufacture
Inventor: KIMURA TATSUYA
IPC: H01S5/06
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To eliminate the occurrence of deviations in the connecting section between a light absorbing layer and an active layer, by making the formation of a contact layer possible in a butt joint type semiconductor laser provided with a modulator having a quantum well containing an AlInAs layer in the light absorbing layer. SOLUTION: The formation of a contact layer is made possible by suppressing the formation of a polycrystalline product by making Al atoms escapable from the surface of an SiO2 mask for selective growth by reducing the width of the SiO2 mask to <=10 μm. In addition, the occurrence of deviations in the connecting section between a light absorbing layer 2 and an active layer 3 can be prevented by exposing the surface of an InP substrate 1, by performing selective etching using the SiO2 mask and forming the absorbing layer 2 on the surface of the substrate 1 on the basis of the surface of the substrate 1.

Title: Circular saw
Inventor: KAJIYAMA FUYUHIKO
IPC: B23D61/02
Filed: 1995-02-18
Abstract: PURPOSE: To provide a circular saw capable of cutting a pipe material to be cut securely without producing ring-shaped burrs. CONSTITUTION: In a circular saw where blade bodies 12 are formed on the outer periphery of a disk base metal 11 at a fixed pitch and a blade 23a with a specified chip separating groove 19 is provided at the flank 17 of each blade body 12, the flank 17 of each blade 23a is formed roughly in an angle shape. Then it can cut a pipe material to be cut while cutting it in a reverse V-shape. Thus, even if a cutting resistance during cutting is less and the residual part of the material to be cut becomes less after advancement of cutting, a stress due to the cutting force and pressing force of the circular saw acts less on each cutting surface, and the production of ring-shaped burrs can be prevented securely.

Title: Flat assembled-type battery
Inventor: YOSHIOKA MICHIE
IPC: H01M2/20
Filed: 1994-03-24
Abstract: PURPOSE:To restrict the total height of a flat assembled-type battery low, and to reduce the dispersion thereof. CONSTITUTION:Adhesive layers 9, 10 at a predetermined thickness are attached to both front and back surfaces of a conductive sheet 7, and multiple conductive grains 12, which are formed into the spherical shape having a diameter nearly equal to the thickness of the adhesive layers 9, 10, are arranged so as to be embedded in the conductive sheet 7 to form a conductive double face tape 6. This conductive double face tape 6 is used to attach both of flat batteries 3, 5 to each other for connection. Since the multiple conductive grains 12 inside of each adhesive layer 9, 10 and the conductive sheet 7 surface-contact with each other, the conductive double face tape 6 shows the excellent conductivity. Consequently, since a process for performing the spot-welding to a metal plate to bend it into the Z-shape is eliminated, the working efficiency is remarkably improved. Furthermore, since the heat energy is not generated, a danger that the active material inside of the flat batteries 3, 5 is broken to generate the lowering of voltage is eliminated.

Title: Clutch mechanism
Inventor: KASAGI SEIJI
IPC: F16D13/08
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To provide a low-cost clutch to ensure release of a clutch. SOLUTION: In a clutch mechanism to transmit rotation of an input sleeve 32A to an output sleeve 34 through the inner periphery of a coil spring 38 in a tension state, when rotation of the input sleeve 32A to the output sleeve 34 is released, the spring 38 is forcibly rotated and loosened. Since incomplete release of the spring 38 during release of the clutch is brought into complete release, a friction force between the spring 38 and the input sleeve 32A is reduced, provision of a decreased life for the spring 38 and the input sleeve 32A is prevented and the generation of slide noise (foreign noise) between the spring 38 and the input sleeve 32A. Further, since there is no need for the use of an individual electromagnetic clutch and independent motor, a cost is not increased.

Title: Trouble detection system for counter
Inventor: OGURA TAKAYUKI
IPC: H03K21/40
Filed: 1988-03-07
Abstract: PURPOSE:To confirm the normal action of a counter with a simple means by preparing an expected value at a time next to the counted value of the counter by means of an expected value preparing circuit, comparing the non-coincidence with the counted value of the counter, and detecting a trouble. CONSTITUTION:A counter 1 counts an input clock CLK and outputs a counted value (n) at a certain time tn. An expected value preparing circuit 2 prepares and outputs a value [n+1], in which a numeric value 1 is added to the counted value (n) at the time tn of the counter 1, as the expected value at a next time t(n+1). An output circuit 3 inputs and holds the expected value [n+1] outputted by the expected value preparing circuit 2 at the time tn, and outputs the expected value [n+1] at the time t(n+1). A non-coincidence detector 4 compares the expected value [n+1] outputted by the output circuit 3 at the time t(n+1) with the counted value counted by the counter 1 at the time t(n+1), and when the non-coincidence is detected, the counting action of the counter 1 is decided to be defective. Thus, a hardware for detecting trouble can be simplified.

Filed: 1989-03-07
Abstract: PURPOSE:To curtail the number of cables by setting a differential signal output of an encoder to floating and forming equivalently an encoder disconnected state, at the time of abnormality of the encoder, and detecting it by a controller side. CONSTITUTION:At a normal time, a signal generated by an encoder signal generating circuit 1a of an encoder 1 is sent to a controller 2 through a cable 3 by a differential output use integrated circuit 1c, and received by a differential input use integrated circuit 2a.

Abstract: PURPOSE:To easily recognize that a part of a recording tape which is to be reproduced and listened has come to the end by switching a light emitting element from ON to OFF status. CONSTITUTION:When a reproducing switch 10 is closed, a message recorded in a tape 1 is reproduced, a signal is outputted from the terminal 15 of a control circuit 8 and a display circuit 23 is actuated to turn on a light emitting diode 24. A counting signal is generated by the revolution of a reel shaft 2 and inputted to an up down counter 4. Since the counted value of the counter 4 coincides with the counted value of the counter 18 when the message is reproduced up to the point from which the rewinding of the tape 1 has been started, a signal is outputted from a comparator 25 to turn a display circuit 23 to unactuated status and turn off the light emitting element 24. Consequently it is easily recognized that the part to be reproduced and listened has come to the end.

IPC: G06F11/00
Filed: 1982-04-01
Abstract: PURPOSE:To perform recovery for a fault regardless of the kind of the fault and to utilize a memory, by rewriting an instruction code in the memory together with the parity bit of a parity error generator, when a parity error is detected in the instruction code and there is no output from a detecting circuit. CONSTITUTION:The parity error of the insturction code read out of a control memory CS is checked by a parity checker CP and a parity bit for the instruction code is generated by the parity generator PG. Further, the detecting circuit EFD discriminates between the significant part and unused part of an operation code to be written in the CS and the instruction code to be written in the CS is compared with the instruction code read out of the CS to generate an output if a dissident code is found. Then, while the instruction code read out of the CS has a parity error and the EFD generates the output, the parity bit and instruction code are rewritten in the CS through an AND gate to perform recovery for a fault without reference to the kind of the fault.
