Title: Connection of armature coil to commutator
Inventor: OOHITO HAYATO
IPC: H02K13/04
Filed: 1997-01-18
Abstract: PROBLEM TO BE SOLVED: To connect an armature coil to a commutator with high efficiency by oscillating the leading part of the armature coil in a pressed condition against a commutator segment for peeling off an insulator, and electrically- heating the leading part. SOLUTION: The leading parts 3a, 3b of an armature coil are disposed in such a condition as they are overlapped in a direction running along the axial center of a rotating shaft 1 at the outer periphery surfaces 4a of a plurality of commutators 4 which form a commutator S. The chip 11 of a pressuring body 7 is pressurized with a prescribed pressure from the upper part of them. When an ultrasonic wave generating device 8 is operated under this condition, an ultrasonic wave is generated, and the pressuring body 7 oscillates in the direction of an arrowhead 13. As a result, the chip 11 oscillates in the same direction, and an insulator in the leading parts 3a, 3b of the armature coil is peeled off. Heavy-current runs through the chip 11 via the commutator segments 4 where the leading parts 3a, 3b of the armature coil are pressed, and the chip 11 is heated to a prescribed temperature.  The leading parts of the armature coil are melted locally and connected to the commutator segments.

Title: Power steering device
Inventor: TOKUMOTO YOSHITOMO
IPC: B62D5/083
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To provide a power steering device by which fuel consumption of a vehicle can be reduced without incurring reduction in a steering feeling and generation of a noise. SOLUTION: A power steering device has a hydraulic actuator 18 to generate steering assisting force by pressure oil supplied through an oil pressure control valve 23 from a pump 37 driven by a motor 50 which is put at steering assisting speed at steering assisting time and is put at standby speed at steering assistance released time. A pressure oil supply pipe to the control valve 23 from its pump 37 has a main pressure oil supply part 82 and an auxiliary pressure oil supply part 83. When rotating speed of its motor 50 is increased to steering assisting speed from standby speed, the auxiliary pressure oil supply part 83 is selected until preset time passes after a speed increase is started, and the main pressure oil supply part 82 is selected after its preset time passes, as a pressure oil supply passage to its control valve 23.  A length of a part elastically deformable by oil pressure of its auxiliary pressure oil supply part 83 is set shorter than a length of a part elastically deformable by oil pressure of its main pressure oil supply part 82, or is set to zero.

Abstract: PURPOSE:To get rid of any mixing of an out ball and a winning ball by setting up a winning ball gathering chute at the lower part than an out port, while constituting an out ball guide chute so as to be reached to the back of a winning ball gathering plate after piercing through an winning ball gathering space in the longitudinal direction. CONSTITUTION:Both first and second winning ball gathering chutes 33, 153 are set up in the lower part than an out port 20, and it is so constituted that an out ball guide chute 158, guiding out balls guided to this out port 20, is made so as to be reached to the back of a winning ball gathering plate 151 after piercing through winning ball gathering spaces 24, 157 in the longitudinal direction. Accordingly, a vertical distance between a lowermost winning port being set up in a floating area and the winning ball gathering chutes 33, 153 is made longer, whereby a large quantity of winning balls can be stored as much as a portion for that. On the other hand, out balls from the out port 20 are reached to the back of the winning ball gathering 151 by way of the guide chute 158 and discharged out. Thus, any mixing between the out ball and the winning ball is preventable.

IPC: H02J7/35
Filed: 1994-02-17
Abstract: PURPOSE:To constitute a solar battery power supply system which provides an interface with a solar array bus lockup system easily even when a plurality of charging/discharging systems are present.

Title: Clock signal extracting circuit
Inventor: HARA HIROSHI
IPC: H03K5/00
Filed: 1993-02-08
Abstract: PURPOSE:To extract a clock signal to be held at normal duty at all times without being affected by the surrounding temperature by automatically and variably adjusting the delay time of first and second delay circuits corresponding to the level of a DC signal outputted from a filter circuit. CONSTITUTION:Since the time constant of a low-pass filter 9 is set to a value larger than the cycle of a clock signal SCR, first of all, a feedback control circuit composed of the low-pass filter 9 and a buffer circuit 10 generates a signal at a DC level in proportion to the duty of logic '1' and '0' of the clock signal SCR by integrating the clock signal SCR. A DC signal Sg is generated by amplifying this signal at a fixed amplification factor by a buffer circuit 10. Then, this DC signal Sg controls the delay time of first and second delay circuits 5 and 8. Thus, the clock signal SCR is held at the normal duty at all times.

Title: Probe card for microwave
Inventor: WAKATA GENICHI
IPC: G01R1/067
Filed: 1986-01-31
Abstract: PURPOSE:To inspect the characteristics of an integrated circuit for microwave by a method wherein a probe using a stripline type feeder is made to correspond to the high-frequency signal input/output terminal of an inspection object integrated circuit. CONSTITUTION:The reason that an elasticity-rich material is chosen for a metal plate 1a equivalent to a conductor on the shielding side of a coaxial cable 2 is for guranteeing a reliable connection of an integrated circuit terminal and a metal protrusion 1d by making the whole probe part hold a spring effect. Such a probe 1 using a stripline type feeder is brought into contact to the integrated circuit terminal part 13 formed on the surface of a semiconductor chip substrate 12 so that the feeder generates sags due to the contact pressure of the metal protrusion 1d of the probe point part and the terminal part 13. Moreover, the part of a stripline 1c is also completely covered its upper side with the metal plate 1a which is used as the conductor on the shielding side and sealed. Accordingly, even when the high-frequency signal of an order of GHz is handled, an undesirable electric induction is never generated through the point part of the probe unlike the case a coaxial cable is used for the probe.
