Title: Cassette loading device
Inventor: YOSHIKAWA KIKUO
IPC: G11B17/04
Filed: 1987-04-30
Abstract: PURPOSE:To surely draw a cassette into a loading position with non-impact by location it with pressure contact to the seating face at a fixed side by an elastic means. CONSTITUTION:When a cassette 10 is inserted and its inclined face is collided with the cassette holding claw 42 of a chuck link 43, this holding claw 42 is pushed to the external side, the chuck link 43 is rotated in clockwise direction, the holding claw 42 is mounted onto the cassette 10 side face and slided. When the cassette 10 reaches a push-in chucking position (or discharging position), the holding claw 42 is ushed with spring force into the recessed part 14 of the cassette 10, which is subjected to chucking with the press engagement of the chuck link 43 energized by a spring 44 and held so as to move in the backward and forward direction together with a sliding member 28. The cassette 10 can thus be surely drawn to the loading position with non-impact and surely returned to the discharging position.

Title: Lockup damper device of fluid transmission device
Inventor: MAKINO TETSUYA
IPC: F16H45/02
Filed: 1995-05-08
Abstract: PURPOSE: To reduce a cost and prevent the generation of a rattling noise at the drive force transmission time by installing a drive plate integrally with a lockup piston on the inside position of the outer peripheral flange of the lockup piston. CONSTITUTION: In a torsional vibration absorption operation around a shaft, a drive shaft 7 is installed integrally with a lockup piston 6 on the inside position of the outer peripheral flange of the lockup piston 6. At the switching time from release to lockup or from lockup to release, the drive force transmitted to the lockup piston 6 is changed suddenly and the drive force transmitted by a load change is changed even in a lockup state (slip lockup state), but in this case, the torsional vibration around a shaft included in a transmitted drive force is absorbed by the expansion/contraction of a coil spring 9 in response to the relative rotation displacement between the drive plate 7 and the driven plate 8 of a lockup damper 10.

Title: Holding device
Inventor: TSUNASHIMA KENICHI
IPC: G05F3/26
Filed: 1988-05-02
Abstract: PURPOSE:To stabilize the holding voltage even with a small-capacity capacitor for a differential amplifier having a current mirror circuit included in an active load circuit by controlling the current supplied to a capacitor which supplies the holding voltage. CONSTITUTION:The buffers of both TR Q12 and Q13 are added to a current mirror circuit 2 serving as an active load circuit of a differential amplifier 1. As a result, the Early's effect due to the potential difference between the bases and the collectors of both TR Q8 and Q9 is reduced. The collector and the base of the TR Q8 serve as the input 7 of the circuit 2 with the collector of the TR Q9 serving as the output 8 of the circuit 2 respectively. The output voltage of a capacitor C is applied to the base of a TR Q14 from the emitter of a TR Q10 serving as a 1st TR of an emitter follower and then taken out of the emitter of the TR Q14 in the form of voltage. A TR Q11 cascaded to the collector of the TR Q10 also serves as a TR which detects the base current. Then the base of the TR Q11 is connected to the collector of the TR Q8 serving as the input 7 of the circuit 2. The base current of the TR Q10 flows into the capacitor C from the collector of the TR Q9 for compensation of the base current.

Title: Controller for action of accumulator in continuous treating line
Inventor: KATOU HIROKI
IPC: B65H77/00
Filed: 1979-08-28
Abstract: PURPOSE: To keep the strip under the specified tension, to prevent the scratch flaw, the sheet flow, and the sheet rupture, and to improve the commodity value, by comparing the tension of the strip laid across the upper and lower roll group with the set point, and by adjusting the distance between rolls of the upper and lower roll group.  
     CONSTITUTION: The aim value of the tension given to the strip 10 is previously set in the setter 24, and the tension acting on the strip 10 is detected by the load cell 23. The difference between this detected value and the aim value is amplified by the amplifier 25, and the command is sent to the relief valve 21. Hereupon, if the detected tension value is higher than the aim value, the pressure of the relief valve 21 is reduced, and a part of the pressure oil is discharged from the discharge port 21a to the oil tank 26; hereby, the pressure of the cylinder 18 is controlled to the specified value. If the detected tension value is lower than the aim value, the pressure of the relief valve 21 is increased, the pressure of the cylinder 18 is heightened, the carriage 12 is lifted up, and the tension of the strip 10 is increased.

Abstract: PURPOSE:To disorder part of an MQW active layer of a semiconductor superlattice structure in a self-aligned manner by forming a resonator whose ends are provided with thin film containing a substance capable of disordering the MQW active layer at high temperature, and then heating the resonator ends. CONSTITUTION:A lower clad layer 32, an active layer 33, an upper clad layer 33 of a superlattice structure, and a contact layer 35 are grown in sequence on a wafer 31. After the wafer is cut into chip substrates of a predetermined size in a normal way, ZnO films 36A and 36B are deposited on their sides by sputtering on a ZnO target. A current is supplied between the substrate and the contact layer to heat locally near the active layer and resonator ends 38A and 38B. As a result, Zn diffuses from the ZnO films 36A and 36B into the active layer, and thus the ends of the semiconductor superlattice structure are locally disordered in a self-aligned manner.

Abstract: PROBLEM TO BE SOLVED: To make a battery replaceable with a charged battery at necessary time, by providing an electrode connected to a battery side electrode in a battery mounting condition to be formed with a power feed circuit in a conveying carriage also an electrode connected to the battery side electrode in the battery mounting condition to be formed with a charge circuit in a battery rack. SOLUTION: A battery 8, having a battery side electrode for a charge concurrently for a power feed, automatically forms a power feed circuit through this electrode when the battery is mounted in a conveying carriage 6 and automatically forms a charge circuit when the battery is mounted in a battery rack 5. A fork 4 in a stacker crane 1 transfer loads in reverse the charged battery 8 from the battery rack 5 into the conveying carriage 6. Thus by automatically replacing the battery 8 in the conveying carriage 6 with the charged battery at necessary time, troublesome hazard work required for human hands can be eliminated in removing/mounting in charging of the battery 8. In this way, the conveying carriage with the battery serving as a power source can be efficiently operated.

IPC: H04M3/22
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To reset an original backup communication state without performing again a circuit backup operation when a power supply is cut during the backup communication and then restored. SOLUTION: When the power supply of a circuit backup device is cut during the backup communication and then restored, a CPU 22 reads the contents of a holding part 24 and confirm state that is set before the power supply is cut. If it is confirmed that the state set before the cut-off of the power supply is equal to a backup mode, the CPU 22 reads the telephone number of the opposite party from a holding part 25 and instructs a control part 23 to start the call control with the telephone number of the opposite party used as an originating number. Then the backup communication is possible via execution of the originating call control procedure of the part 23. When the backup communication is over, the CPU 22 clears the contents of both holding parts 24 and 25.
