Title: Two-step function key unit
Inventor: ASANO KIYOMITSU
IPC: G05G1/02
Filed: 1979-01-25
Abstract: PURPOSE: To secure the free formation of the single input signal and the repeat input signal by providing the main and second substrata of the electrostatic coupling print plate plus the first and second actuators and thus securing the two-step action for the key top operation.  
     CONSTITUTION: With the first push of key top 7, first actuator 13 is pressed to main substrate 19 by the compression force of spring 16 and by overcoming the sucking force of permanent magnet 4. At this moment, action plate 18 hits the print of substrate 19, and the signal key input signal is delivered through the electrostatic coupling. In case the coding action same as that carried out by the first push of key top 7 is repeated, top 7 is pushed down more in the state under which actuator 13 is pressed to substrate 19. Thus press bar 31 of top 7 touches the pressure reception end of second actuator 23. And actuator 23 is pressed down against the force of spring 29 and then pushed by second substrate 28 to have the electrostatic coupling with the print formed on substrate 28. Thus the repeat input signal is extracted.

Title: High-and-dry countermeasure circuit for public telephone set
Inventor: TANAKA KEISUKE
IPC: H04M17/00
Filed: 1990-01-16
Abstract: PURPOSE:To enable the use of a public telephone set by supplying station power from an exchange when a transmitter/receiver is hung up by delaying a check signal from the exchange in a high-and-dry state and preventing the relay contact of the public telephone set from being operated. CONSTITUTION:The exchange sends out a constant check pulse to check whether the transmitter/receiver of the public telephone set is hung up or not. This check signal is detected by a photocoupler PC in a loop detection circuit 3 and sent out to one input terminal of an AND circuit 6 as an output signal (a). The check signal is sent out through a capacitor C1 to a comparator 4 as well and the output signal is delayed by a delay circuit 5 and sent out to the other terminal of the AND circuit 6. Since the check signal is delayed, a transistor Q1 and a relay GS are not operated and a contact gs is not closed, either. Thus, when the transmitter/receiver is hung up afterwards, the station power is supplied from the exchange and the public telephone set can be used.

Title: Method and device for circuit simulation
Inventor: KIYOI YOSHINOBU
IPC: G06F17/50
Filed: 1993-01-19
Abstract: PURPOSE:To accurately find parameters of an MOS transistor(TR) in an optional shape by setting model parameters in the form of a shape dependent function. CONSTITUTION:The circuit simulation method extracts circuit connection data by a circuit data generation part 30 after circuit input. The model parameters and circuit data including the coefficient of this shape dependent function are read in by the circuit data read-in part 40 of a circuit simulation part. A circuit simulation device refers to the values of the stored model parameters and calculates DC electric characteristics S4-S7 from the circuit equation of an MOS TR circuit. For the calculation of the DC electric characteristics, a Newton-Raphson method is used. The calculation of the DC electric characteristics is therefore repeated S8 until the solution of the circuit equation is converged on within a specific error range. Then once the solution is converted on within the error range, the calculation result is outputted S9.

Title: Back regulator circuit
Inventor: BURAIAN AARU PERII
IPC: G05F1/66
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To attain a highly reliable power regulator circuit by controlling the voltage of a load driving output terminal so as to be maintained at a determined fixed value, and controlling a gate drive circuit so as to be turned off within a changeable period. SOLUTION: When the output terminal H0 of the IR2152 type integrated circuit 1 is high and a MOSFET Q1 is on, the voltage between both ends of a free wheel diode D5 is fed back into the terminal C1 of the integrated circuit 1 through a resistor R1 and a diode D3 and becomes equal to DC bus voltage when the Q1 is ON. After an inherent delay, the output terminal H0 becomes low and after the MOSFET Q1 is turned off to remove the bus voltage from the free wheel diode D5, the voltage of the terminal C1 drops at the initial rate determined by internal capacity. The output terminal H0 is kept low until the feedback voltage into the terminal C1 drops to VCC/3 and becomes high after an inherent delay. It is thus possible to attain a highly reliable circuit.

Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To operate a rotating cutter during machining according to the delicate irregularities of a work by fitting an air cylinder, which presses the rotating cutter against the part to be processed of the work at constant pressure for energizing a processing head, between the processing head and a supporter. SOLUTION: In such a condition that the grinding wheel head 7B of a rotating grinding wheel 7 is brought into pressure contact with the part to be machined of a plated cylinder W based on the oscillation of a processing head 5 by action of an air cylinder 30, it is balanced in a condition that the rotating grinding wheel 7 applies constant pressing force onto the part to be machined of the plated cylinder W. If delicate irregularities are generated at the opening edge part of a port in the plated cylinder W during processing, the air cylinder 30 energizes the processing head 5 in such a condition as to bring the rotating grinder 7 into pressure contact with the opening edge part through constant pressing force based on the action of the precise pressure-reducing valve of an air circuit.  It is thus possible to bring the grinding wheel head 7B into pressure contact with the opening edge part at the same pressing force as that against a position which meets teaching data.

Title: Mounting device for flip chip integrated circuit
Inventor: NISHIDA KAZUTO
IPC: H01L21/52
Filed: 1992-01-21
Abstract: PURPOSE:To perform pushing on a substrate just enough by providing a stopper to control a space between the end face and the substrate to a prescribed interval while abutting on the substrate around the end face attracting a flip chip IC of an suction nozzle. CONSTITUTION:A third stopper 62 abutting on the substrate 2 and controlling a space between the end face and the substrate 2 to a prescribed interval S3 is provided around the end face of an suction nozzle for mounting a flip chip IC on the substrate 2. Thereby, the degree of proximity between the flip chip IC and the substrate 2 at the time of pressing the flip chip IC on the substrate 2 can be made constant regardless of a warp of the substrate 2 or the like. Further, since a parallelism of the flip chip IC with the substrate 2 can be guranteed to high accuracy, generation of short circuit and unjunction between the neighboring junction parts due to protrusion of a conductive junction material 37 can be avoided just enough pressing the flip chip IC on the substrate.

Abstract: PURPOSE:To reduce the capacity of a smoothing capacitor by providing a capacitor between both ends of a rectifying circuit which applies the full wave rectification to all N pieces of electric signals received via a coil and having a prescribed phase difference and synthesizes these electric signals. CONSTITUTION:A rectifier circuit 5A applies the full wave rectification to the inductive voltage generated by three sheet coils 41 - 43 provided in an IC card 2A in response to three sheet coils 31 - 33 provided in a terminal equip ment 1A. That is, the voltage generated by the coils 31 - 33 for IC card and the circuit 5A has a 60 deg. phase difference (half of 120 deg.). Thus the DC voltage of good quality can be obtained with the capacity of a capacitor which is <=3 times as much as a conventional smoothing capacitor (180 deg.) having the compara tively large capacity. As a result, a smoothing capacitor 6A requires just 1/3 capacity compared with the conventional capacitor.

Filed: 1986-01-17
Abstract: PURPOSE:To prevent galling from occurring when a bearing is press-fitted by applying tumbler machining to an outer ring bored with a strut inserting hole to corner-slouch around the hole before heat treatment then applying heat treatment and tumbler machining. CONSTITUTION:A needle-shaped roller bearing 4 is constituted of an outer ring 12, a needle-shaped roller 13 and a holder 14, and a hole 15 is bored on the outer ring 12. The outer ring 12 is produced by boring the hole 15 on a raw material, next applying tumbler machining to corner-slouch around the hole 15, then applying tumbler machining again for heat treatment and scale removal. Therefore, the periphery of the hole 15 is chamfered 19 in a circular shape, and no burr is protruded on the outside of the outer ring 12. Accordingly, galling can be prevented from occurring when the needle-shaped roller bearing 4 is press-fitted into the coupling hole of a caliper without applying positive chamfering around the hole 15 by press machining.
