Title: Power amplifier
Inventor: TERADA NORIO
IPC: H03F1/00
Filed: 1983-08-05
Abstract: PURPOSE:To miniaturize an external power switch by using independently the external power switch as a means for operating only a bias circuit supplying a bias voltage to an amplfier stage. CONSTITUTION:An electronic switch 7 is connected between a bias circuit 13 and a power supply 1 and the electronic switch 7 is made conductive through the turning-on of the external power switch 12 of mechanical contact whose one end is connected to a reference point, e.g., an earthing point 8. Then a bias circuit 13 is connected to a power supply 1 through the turning-on of the electronic switch 7 and activated, thereby activating an initial stage amplifier stage 4, a pre-driver stage 5 and a power amplifier stage 6. Since the on-current flowing to the external power supply 12 is a minute current to turn on the electronic switch 7, the switch is miniaturized.

Title: Molten liquid discharge structure for melting furnace
Inventor: NIEKAWA YUTAKA
IPC: B22D41/00
Filed: 1991-06-17
Abstract: PURPOSE:To prevent the solidification of the molten liquid when it is discharged from the melt discharge part of a melting furnace for waste matter and thereby prevent the clogging of a discharge opening with the melt or its adherence to the discharge opening periphery. CONSTITUTION:A raised part 13 is formed on the bottom part 12 of a molten liquid discharge part 11 of a melting furnace projecting inwardly of the furnace and a discharge opening 15 is provided in the top part 14 of the raised part 13. Since the discharge opening 15 is located at the top part 14 of the raised part 13, i.e., a high temp. part inside the furnace, this structure causes the temp. of the discharge opening 15 and its periphery to become sufficiently high to prevent the solidification of the molten liquid 16 discharged from the discharge opening 15. For this reason, there is neither clogging of the discharge opening 15 with the solidified molten liquid 16 nor its adherence to the periphery thereof.

Abstract: PURPOSE:To increase take-up quantity of the captioned endless chain type device by fixing, to a mobile take-up frame, a toothed wheel and U-turn part of a supporting outside rail equipped with roller transfer parts movable along a direct line part. CONSTITUTION:When a driving endless chain 5 is slackened, a pair of left and right nuts 96 are clamped and a mobile frame 26 is moved in the direction of an arrow 40. At this time, an engagement member 32 at the inner end part of a mobile frame 26 slides in the dovetail groove of a fitting part 17 for a supporting inside rail 7 to strain the chain 5, while a triangular part 39, on the outer edge of a roller transferring part 38 of a rail U-turn part 8a which moves in one body with the frame 26, is moved along the straight line part 8b of a fixed side rail. Accordingly, no difference in level is produced between the straight line part 8b and the U-turn part 8a even after take-up of the chain 5, transfer of the roller being smoothly performed. The take-up quantity is increased due to this structure.

Title: Flexible cable for industrial robot
Inventor: HAMAGUCHI NAOKI
IPC: H01B7/04
Filed: 1987-06-09
Abstract: PURPOSE:To enable a cable to be replaced intentionally by arranging a lead wire, which is formed into a diameter larger than that of a core, together with the core, and then causing the lead wire to be disconnected earlier than the other core with respects to the bending stress acting upon it repeatedly so as to warn that the lifetime of the other core will expire shortly. CONSTITUTION:In a fine-line conductor 9 is arranged a lead wire 14, which is formed into a diameter larger than that of the fine-line conductor 9 so that the lead wire 14 is disconnected earlier than the other fine-line conductor 9 by a repeatedly acting stress upon it so as to warn the disconnection of the fine-line conductor 9. Accordingly, when an industrial robot is used over a long term and the core 9 becomes fatigued so that the lifetime thereof is drawing near to its end, the lead wire 14, which has a shorter life than that of the core 9, is disconnected to cause an alarm unit to function so that the lifetime of the other core 9, that is, the lifetime of cables 7, 8, can be warned in advance. Thereby, the cables can be replaced intentionally and with good timing.

Abstract: PURPOSE:To prevent a chair from interfering with surrounding objects when the chair is swivelled for a customer to sit on or rise from the seat of the chair by separating a step of the chair from the seat and providing the step and seat respectively with separate elevator devices for vertical movements. CONSTITUTION:A power section comprises an elevator device for the vertical movement of a step 1 with a master cylinder 2 and another elevator device for the vertical movement of a seat 3 with a sub-cylinder 4. When the seat 1 and the step 2 are to be lowered, they are synchronously lowered by opening a switching valve 31. The seat 3 can be moved independently vertically by operating a motor 28, opening a switching valve 30 to supply oil independently to the sub-cylinder 4, and opening a switching valve 32 to independently discharge oil. Optimum heights of the seat 3 and the step 1 can be set according to the physical build of a customer by changing their relative heights. Even if the chair is swivelled, no interference with surrounding is caused because of absence of projections out of the seat.

Title: Optical recording and reproducing device
Inventor: KOISHI KENJI
IPC: G11B7/005
Filed: 1982-08-18
Abstract: PURPOSE:To discriminate an address region, etc. having a high output and high S/N, by receiving a far viewfield image of the reflected light given from an optical disk by a split photodetector having a dividing surface vertically to a guide track and detecting the address region, etc. with the differential output of the photodetector. CONSTITUTION:A focus detector 14 contains two split photodetectors F1 and F2 at the condensing positions of a reflecting system, and a tracking detector 15 contains four split amplifiers T1-T4 having dividing surfaces parallel and vertical to a guide track 1. The tracking control signal is obtained from differential outputs 31a and 31b of photodetectors and the output of a differential amplifier 19. For detection of the sector separating signal, the sector separating region is detected from the output of a differential amplifier 33. Therefore the dividing surface of the photodetector is set vertically to the track 1 to extract a differential output. Thus the sector separating region can be detected with high S/N and a larger amplitude than a case where the sector separating region is detected from the total reflected light quantity. This improves a discriminating function between address and sector regions.

Filed: 1978-11-24
Abstract: PURPOSE: To improve the throughput of read operation by writing an unreadable code at a fixed position of a memory and then by displaying and correcting an input character pattern through a keyboard control part.  
     CONSTITUTION: Under the control of control part 1, an optical character reader reads characters on a 1st line of document 10 to be read in the order of 11...14. Then, control part 1 writes the code of a read result of character 11 inputted from read part 2 at the 1st digit of an area and then reads character 12 next. In this case, when a character is unreadable, control part 1 writes the unreadable code from read part 2 at the 2nd digit of memory 7 and then displays 4 an input character pattern through keyboard control part 3, thereby correcting the unreadable character. Consequently, characters can be read and corrected at the same time, thereby improving the throughput of read operation.

Title: Optical fiber gyro
Inventor: USUI RYUJI
IPC: G01C19/72
Filed: 1992-06-04
Abstract: PURPOSE:To obtain a stable output even under a vibration environment. CONSTITUTION:Interference light in clockwise and counterclockwise directions which is propagated through an optical fiber coil 15 is converted to electric signal by a light receiver 17. A frequency of the signal which is higher than the maximum frequency of external vibration which is predicted within a vibration noise detection circuit 25, for example, a component which is equal to or higher than 3000Hz, is filtered out and also the minimum frequency of the predicted external vibration, for example, a component which is equal to or lower than 100Hz and a DC content, is filtered out thus extracting external vibration noise components. The extracted vibration noise components are supplied to a light source driving circuit and light loss fluctuation reaching the light receiver 17 from a light source 11 via the optical fiber coil 15 based on external vibration is canceled out.
