Title: Device for compression molding lead-equipped brush
Inventor: KURATA MASANORI
IPC: H01R43/12
Filed: 1993-12-22
Abstract: PURPOSE:To simplify constitution by dividing a powder-compressing die into a movable die and a fixed die, providing a powder molding chamber between the surface of junction between the dies, providing the fixed die with a sliding hole extending in a direction perpendicular to the direction of compression, and passing a lead through the hole thus processing the powder. CONSTITUTION:As upper 13 and lower 14 cam bodies are rotated together with a main spindle 12, an upper punch 26 rises, a lower punch 31 drops, and a lever 38 is rotated in the direction of the arrow so that a feeder 37 is driven up to a position where it covers the molding chamber 22a of a die 22. As the punch 31 is driven in the downward direction, powder P is fed to the molding chamber 22a from the feeder 37. Then the end of a lead 55 projects from the end of a guide pipe 56 by a predetermined size and is positioned so as not to project into the molding chamber 22a. When the feed of the powder P is completed, the lever 38 is rotated in the reverse direction to retreat the feeder 37 and to advance the guide pipe 56, thereby forcing the end of the lead 55 to project into the molding chamber 22a. Then rotation of the main spindle 12 causes the upper punch 26 to fall and the lower punch 31 to rise, thus compression molding the powder P inside the molding chamber 22a.

Title: Method for correcting field pole position in synchronous motor
Inventor: TANIMOTO TOMOAKI
IPC: H02P25/022
Filed: 1994-12-27
Abstract: PURPOSE: To obtain a corrective value in current phase with small movement in motor without decreasing an accuracy in pole judgment of electromagnetic force, by increasing an electromagnetic force command up to a temporary target, calculating always an acceleration value, and decreasing a target value during large acceleration, while the target value is increased during small acceleration. CONSTITUTION: In correction of a magnetic pole position of a synchronous motor 6, an amount of correction in applied current phase is so changed that a corrective current phase value for making generated electromagnetic force to zero, regardless of the amount of applied current, is judged from polarity acceleration of generated electromagnetic force. After a corrective current-phase value for maximizing the electromagnetic force is obtained from the corrective value, a current phase to be applied is determined from the corrective value and a temporary field pole position detected by a position detector. As a result, the synchronous motor 6 is operated under vector control.  In these steps, the acceleration value is always calculated while the electromagnetic command value is increased in a monotonous way up to a temporary target and the target value is decreased during larger acceleration, while the target value is increased during small acceleration.

As mentioned above, when Ti/Pt/Au are used, a non-alloyed p-type ohmic electrode can be obtained. Therefore, an n-type, an i-type, and a p-type GaInAs layer, 12, 13, and 14, can be obtained without any special heat treatment, so that the light absorbing layer 13 can be kept high in purity. By this setup, a photodiode of this design can be reduced in dark current.

IPC: F16H61/14
Filed: 1994-12-27
Abstract: PURPOSE: To provide a lockup control device having an operating fluid cooling circuit not reducing the lockup capacity. CONSTITUTION: A valve 11 selectively feeds the fluid of a circuit 3 toward a control valve 2 to a cooler circuit 12 or a drain circuit 13 and regulates it to the pressure corresponding to a spring 11b. The control valve 2 responding to the signal pressure Ps feeds the fluid of the circuit 3 to an apply chamber 1A from a release chamber 1R to set a torque converter 1 to the converter state when it is set to the release position 2a, and it feeds the fluid of the circuit 3 in the opposite direction to attain the lockup state when it is set to the lockup position 2b. The excess fluid after being regulated by the valve 11 is fed to a cooler 4 and cooled. The flow quantity to the cooler 4 does not reduce the torque converter flow quantity, and the reduction of the lockup capacity can be prevented.

Title: Ic for power source
Inventor: SHIMODA SADAYUKI
IPC: H02J7/00
Filed: 1989-12-14
Abstract: PURPOSE:To take out constant voltage always with high accuracy by inserting a changeover transistor between a control transistor constituting a series regulater and a feedback resistance. CONSTITUTION:A changeover transistor 3 is inserted between the drain of a control transistor constituting a series regulator 8 and a feedback resistance 10. The control transistor 9 can vary the resistance value so that the output terminal 5 may be at constant voltage. Accordingly, even if a changeover transistor 3 whose resistance fluctuates is inserted between the control transistor 9 and the output transistor 9, that is, the feedback resistance 10, the resistance value of the control transistor 9 changes in the reverse direction to the direction of the resistance change of the changeover transistor 3, so constant voltage independent of the quantity of currents is output to the output terminal 5.

Title: Mounting device for power unit
Inventor: OYABU HIROSHIGE
IPC: F16M7/00
Filed: 1987-12-22
Abstract: PURPOSE:To provide a normal vibration isolating function to control the large movement of inner and outer tubes about their axes by providing stopper rods in the inside of a cavity of an elastic body with a fixed gap kept between them in a direction perpendicular to or about the axes of the above-mentioned tubes. CONSTITUTION:Since a fixed gap exists between a stopper bolt 11 and the inside of a cavity 10 in an elastic body 7, so far as a power unit vibrates at an amplitude within the fixed gap during its normal operation, its vibration is not directly transmitted toward a car body, and thereby isolated. In addition, when the rolling motion of the power unit attempts to make an outer tube 3 rotate largely round the axis of an inner tube 6, intermediate members 12 of the elastic body 7 can abut on the stopper bolts 11 to control the rotation of the outer tube 3, and even when the outer tube 3 attempts to move largely in a direction perpendicular to the axis of the inner tube 6, the movement can be similarly checked.

Abstract: PROBLEM TO BE SOLVED: To prevent excessive sliding operation of a release fork by arranging an expansion part for enclosing the end side end part of the release fork on a transmission case, and opening an opening part for restricting an operating range of the other end side end part of the release fork on the expansion part when the release fork is operated. SOLUTION: When a clutch pedal is stepped down for releasing a clutch 8, a release fork 36 is slid interlocking a clutch cable, a release bearing 18 is moved in an axial direction, and the clutch 8 is released. When a step-down operation of the clutch pedal becomes an excessive condition, an end part 36b of the release fork 36 whose end part 36b is faced to an opening part 64 formed on an expansion part 60 integrated with a transmission case 12 is brought into contact with an edge part 62-2 of the opening part 64, and thereby, an oscillating operation of the release fork 36 is restricted. An over stroke operation of the clutch pedal is damped by a spring arranged on the clutch pedal side.

Abstract: PURPOSE:To eliminate the trouble for redialing and to facilitate an operation by enabling a user of a slave station to make a call without dialing when the data transmitted from a key station includes a telephone number. CONSTITUTION:When the message data includes the telephone number for which a control signal is added, the telephone number is displayed on a display part 25 by operating a calling operation part 27. Then a signal generation part 28 generates a push-button dialing signal and a push-button dialing signal tone is outputted through a speaker 24. Then the handset of a push-button telephone set is hooked off and the push-button dialing signal tone is inputted to the transmitter, thereby making a call similarly to the operation of the key pads of the push-button telephone set. Consequently, the trouble for redialing is eliminated and the operation is facilitated.
