Patent JP-H01241838-A (JP)
Title: Wire bonding
Inventor: OKU KOJI
IPC: H01L21/607
Filed: 1988-03-23
Abstract: PURPOSE:To stably detect a landing point by detecting the phase difference at a resonance frequency of an ultrasonic horn at a timing of landing a capillary mounted at the tip of the horn on the bonding pad or inner lead of an IC and determining the point when the phase difference becomes a predetermined value. CONSTITUTION:When the phase of an exciting current is varied by at the time of landing, the output of an operational amplifier 20 is varied in phase, and the output of a multiplier 21 becomes a waveform (g). The variation in the waveform is input to an oscillator controller 22, and a frequency coincident with the resonance frequency varied by landing is output from a voltage control oscillator 12. Phase error characteristic is obtained in response to its phase difference at the time of landing, and the value is compared with a reference voltage v1 by a resistor 24. When it arrives at the voltage v1, a gate pulse 26 indicating the landing range of a pad side is output. Thus, the magnitude of the phase difference is judged as a landing point when the magnitude of the phase difference arrives at a predetermined valve.

Title: Fuel cell, separator for fuel cell, and manufacture therefor
Inventor: TASHIRO AKITSUGU
IPC: H01M8/02
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To easily manufacture a separator, excellent in electrical resistance, gas permeability, liquid swelling properties, and mechanical strength, and satisfactory in moldability, by molding expanded graphite powder having a specific average grain size and mixed with a resin. SOLUTION: Expanded graphite powder having an average grain size of 50 μm or more is previously manufactured and mixed with a resin, and the mixture is molded into a separator. If the average size of the expanded graphite powder is less than 50 μm, the separator is larger in electrical resistivity and inferior in mechanical characteristics, and therefore 80 to 500 μm is preferable. As the expanded graphite powder, expanded graphite having worm-like shapes and compression characteristics, can be obtained, for example, by immersing graphite in a solution with an acid constituent, thereby producing a graphite interlayer compound, rinsing the graphite, and rapidly heating it so as to cause graphite crystals to extend in the C axis direction. This graphite is worked into a sheet-like shape and then pulverized.  As the resin, a non-solvent liquid epoxy resin, a solid epoxy resin, a melamine resin, an acryl resin, a phenol resin, a polyamide resin, and the like are used.

Abstract: PROBLEM TO BE SOLVED: To operate a motor and an engine in the optimal condition in a motor traveling mode and an engine traveling mode by setting a change gear ratio of a continuously variable transmission at the time of releasing a clutch higher than a change gear ratio at the time of fastening the clutch. SOLUTION: Change gear ratio of a continuously variable transmission 5 at the time of releasing a clutch is set at a high value, in cases where acceleration from starting and a low-speed is performed by a motor 4 while releasing a clutch 3, since the motor 4 is provided in an input side of the continuously variable transmission 5, motor torque can be increased larger, as the change gear ratio is set higher, and a large acceleration can be obtained. Furthermore, the maximum rotating speed of the motor 4 is restrained low, and the ordinary rotating speed of the motor is set in a high speed area, and the motor can be operated in an efficient area. On the other hand, since the change gear ratio is low at the time of fastening the clutch, an engine 2 can be operated in the low-speed and high-load condition, and operating efficiency is improved.

IPC: G11C11/413
Filed: 1980-06-02
Abstract: PURPOSE:To obtain a pulsed electric power circuit which operates at a high speed and high stability having large operation margin of a power source, by separating a pulse-component passing circuit for a chip selection signal, etc., from an internal voltage generating circuit for determining a driving signal level of current source. CONSTITUTION:A pulse V1 which corresponds to a binary chip selection signal from an input buffer circuit 8 is applied to a level converting circuit 9 connected to an internal voltage generating circuit which generates a reference potential V'CC with a constant potential difference from a negative power source VEE. Then, the output V2 of a circuit 9 whose high level and low level follow up the potential V'CC is passed through a power amplifier 10 to obtain a high-speed power-source driving signal VPP with excellent stability. The circuit 9, amplifier 10, etc., where this pulse component passes are separated from the internal voltage circuit 11, so the level of the signal VPP following up the potential V'CC follows up the level of the power source VEE: and a current source driven with the signal VPP is hardly influenced by the power source VEE, increasing the operation margin. Therefore, using this circuit minimizes the deterioration in speed performance of a semiconductor storage element and also reduces the power consumption.
