Title: Measuring device for semiconductor integrated circuit
Inventor: YONENAKA KAZUHISA
IPC: G01R31/26
Filed: 1986-11-12
Abstract: PURPOSE:To dispense with the adjustment to the height of contact electrodes by a method wherein the contact electrodes, which are provided on an insulating substrate and come into contact to electrodes in 1 to 1, and wiring conductors, whose one ends are respectively connected to the contact electrodes and whose other ends are arranged toward the peripheral parts of the above insulating substrate, are provided. CONSTITUTION:Contact electrodes 1 are formed by thermally fixing by pressure metal balls on an insulating substrate 3 or by hardening a metal paste after the metal paste is printed on the substrate. Wiring conductors 2 are printed and wired on the insulating substrate 3 and each one end of the wiring conductors 2 is connected to the respective contact electrodes 1. The other ends are arranged toward the peripheral parts of the insulating substrate 3 and the points thereof are connected to a measuring circuit through an external wiring. The contact pressure of the contact electrodes 1 to the electrodes of a semiconductor integrated circuit is set by adjusting the pressure of the insulating substrate 3 to a semiconductor substrate 5. Moreover, a soft insulating material layer is provided between the insulating substrate 3 and the contact electrodes 1 and the contact pressure of the contact electrodes 1 to the electrodes 4 is adjusted. Thereby, as the height of the contact electrodes 1 becomes constant by just keeping constantly the thickness of the contact electrodes 1, the adjustment to the height becomes unnecessary unlike a case where a probe is fixed.

Next, the compound, which is produced by kneading the resulted powder and binder resin each other, is molded with being pressurized to produce a resin compression bond type magnet compact. Moreover, the needless magnetic powder, which is deposited about the circumference, is eliminated, and the compact is heated to be cured, thereby a permanent magnet being produced. Accordingly, a corrosion preventive treatment is performed and both the mechanical strength and the dimensional accuracy of the compact are improved using simple treatments without the magnetic characteristics thereof being degraded.

Title: Amplifier circuit
Inventor: TAKESHITA RITSUJI
IPC: H03F1/02
Filed: 1984-12-24
Abstract: PURPOSE:To minimize power consumption at operation stop of the entire amplifier by using a control signal to shut a current flowing to an amplifier circuit and a abnormality detection circuit. CONSTITUTION:A drive circuit 9 is operated based on a detection signal of ASO detection circuits 7, 8 applies a detection signal to a bias circuit 3 to switch the entire amplifier into the inoperative state. On the other hand, when a control signal Vc is at high level, a standby circuit 2 is operated to apply power to the bias circuit 3, from which a prescribed bias voltage is obtained. Thus, in this case, the entire amplifier circuit is in operative state. When the control signal Vc is at a low level, the power supply of the bias circuit 3 is shut and no bias voltage is obtained. Then the entire amplifier circuit is inoperative in this case. Then the power consumption at operation stop of the entire amplifier is minimized.

Title: Electromagnetic switch
Inventor: TAKASU EIZO
IPC: H01H50/30
Filed: 1992-09-14
Abstract: PURPOSE:To prevent occurrence of chattering, increase in a contact resistance value and abnormally high sound at a contact. CONSTITUTION:A movable yoke 21 is reciprocatably driven by turning on and off the supply of power to a coil 20, and caused to impulsively come in contact with a fixed yoke 19. A feeder terminal 15 comprising an elastic material and an elastic body is provided in a gap between the fixed yoke 19 and a case 12. The impulsive vibration generated due to contact between the yokes 21 and 22 is, therefore, absorbed by the elastic material and the terminal 15 and damped. Consequently, the vibration has no adverse effect on a contact and the occurrence of chattering is prevented. Thus, an increase in a contact resistance value and an abnormally high sound at the contact can be prevented.

Title: Outer yoke structure of outer-rotor hybrid motor
Inventor: HIRATA KAZUYUKI
IPC: H02K37/06
Filed: 1986-11-15
Abstract: PURPOSE:To prevent an eddy current generated in a rotor yoke by constituting said rotor yoke through winding and laminating a thin electromagnetic steel plate in an outer-rotor type hybrid motor. CONSTITUTION:A rotor yoke is constituted by winding of a thin electromagnetic steel plate 1a round outer peripheral faces of permanent magnets 2, 3 of an outer-rotor hybrid motor to form a laminated structure. In this manner, even if a magnetic flux generated from the permanent magnets 2, 3 by rotation of a rotor changes in quantity by the movement with an amplitude increasing and decreasing through the rotor yoke 1 in a circumferential direction, generation of an eddy current can be prevented and an iron loss can be reduced because the rotor yoke 1 is of a laminated structure made by winding of the thin electromagnetic steel plate 1a.

Title: Lead frame for semiconductor device
Inventor: OKAMURA SHINJI
IPC: H01L23/50
Filed: 1988-10-27
Abstract: PURPOSE:To prevent damage to a package resin part when it is packaged and improve heat dissipation effects when a holder is used practically by making the entire holder of an integrated circuit chip hold a position that is lower than an entire lead frame and causing the holder to be exposed from the mainframe of a resin package. CONSTITUTION:The entire rear of a holder 3 of a lead frame in which an integrated circuit chip 1(IC chip) is placed is exposed from a package 2 and an interface between the holder 3 and a resin part 2 is not provided. A prevention against damage when it is packaged as well as radiating properties to a packaged substrate after it is packaged are improved by radiating heat directly from the metal part itself of the IC chip holder 3 without passing through the resin part. As the thickness of the resin part on the surface of the IC chip is made thick by placing the holder 3 at a position that is further low, its step not only increases the mechanical strength of the resin part but also prevents the above resin part from being damaged when it is packaged.

Abstract: PURPOSE:To make an output signal stable and also to improve the S/N by providing an exciting means and a vibrator main body provided with the plural number of 1st vibrators and a 2nd vibrator coupling mechanically loops of the vibration of the 1st vibrators, etc. CONSTITUTION:An exciting means uses a magnet 13 to apply a DC magnetic field orthogonal to a vibrator main body 30 and uses an input transformer 41 to give an AC current through one of the 1st vibrators 31 and excites the main body 30 in a direction orthogonal to the magnetic field and the current through magnetic induction. Then the main body 30 is excited by an input signal given to the means 40 and the vibration of the main body 30 is detected by a vibration detection means 50 and extracted as an output signal. In this case, the main body 30 is divided into the 1st vibrator 31 for excitation and the 1st vibrator 31 for electromotive force detection and the 2nd vibrator 32 couples the lops of the vibrator of the vibrators 31. Since the title filter is isolated electrically but coupled mechanically, a high input component rejection ratio is obtained. Thus, an stable output signal with excellent S/N is obtained.

Title: Subscriber dialing restriction system
Inventor: OGATA HATSUO
IPC: H04M3/22
Filed: 1990-10-09
Abstract: PURPOSE:To prevent invalid operation of an ISDN exchange by implementing a data link interrupt procedure defined in a D-channel signal system layer 2 after dialing restriction is imposed on a relevant subscriber so as to abort a signal defined by the D-channel signal system layer 2. CONSTITUTION:In the case of making dialing restriction to a subscriber 10 accommodated in an ISDN(integrated services digital network) exchange, a subscriber dial restriction controller 40 stores dial restriction information corresponding to the subscriber 10 to a storage means 50 and gives a command of dial restriction of the said subscriber 10 to a layer 2 controller 20 by using a dial restriction signal 41. The layer 2 controller 20 receiving the dial restriction signal 41 sends a data link interrupt signal 21 to an ISDN subscriber 10 by using a data link interrupt procedure defined by a D-channel signal system layer 2 and aborts a D-channel layer 2 signal 22 between the ISDN subscriber 10 and the layer 2 controller 20. Thus, invalid operation of the ISDN exchange is prevented.
