IPC: H01L23/50
Filed: 1984-04-24
Abstract: PURPOSE:To contrive the formation of a bonding part having good bonding characteristic by a method wherein an oxide film 80Angstrom or less in thickness and 0.25mum or less in surface roughness is formed on the surface of a lead frame. CONSTITUTION:A Cu plating of 1-5mum thickness is applied on the surface of the lead frame made of Cu alloy by electroplating using e.g. a bath of cupric sulfate. Next, the surface roughness is adjusted to 0.25mum or less by treatments such as buffing, mirror rolling, chemical polishing, and electrolytic polishing. The method of ultrasonic heating thermocompression bonding, high-frequency heating, or laser heating is adopted as the means of bonding Au wires to the lead frame, at the time of thermocompression bonding, the bonding part is sealed with an inert gas of N2 or Ar, or the inert gas is sprayed there. Bonding is carried out by setting the pressure at 15-60g, the output in ultrasonic heating at 0.1-1.0W, and the time at 10-60ms, and the oxide film 80Angstrom  or less in thickness is formed on the surface of the lead frame. This manner yields bonding strength and excellent interface-exfoliation resistance.

Filed: 1990-03-29
Abstract: PURPOSE: To obtain an asynchronous CMOS high speed chip verse chip data interface by ignoring an arbitrary data depending transition pulse generated while a latch is reset at that point. CONSTITUTION: True and inversion data signals from a differential CMOS input stage 18 are impressed to a pair of negative edge trigger monostable circuits 21 constituted of an invertor 21a and an OR gate 21b. A set pulse S is generated to a latch 22 for each transition of the data signal. The set pulse allows the latch 22 to flip, and a low logical level is applied with VO. This low level is propagated through delay stages 23 and 24, and a reset pulse RST generated farom an OR gate 22a which restores a high logical level with the VO is generated. The rest pulse is continued in a 1/4 period, and the latch 22 is held in a reset stage in this time. A data depending transition pulse generated in the middle of the bit cycle is overlapped by the reset pulse, and masked. Next, an extraction clock is simply extracted from the output of the latch 22 through an invertor 22b.

IPC: G03G21/00
Filed: 1988-04-06
Abstract: PURPOSE:To keep the inside of a copying device clean by detecting a photosensitive body temperature and controlling the pressurizing time of a cleaning blade in accordance with its temperature. CONSTITUTION:A temperature detecting sensor 30 detects a developer temperature, namely, a photosensitive drum temperature, and its detection signal is inputted to a control means 31. The control means 31 discriminates whether the detected temperature is above a set temperature or not, and when the detected temperature is the set temperature or above, a solenoid OFF request of a cleaning blade is turned ON, and when the detected temperature is the set temperature, or below the solenoid OFF request is not turned ON. When the solenoid OFF request is in an ON state after a temperature detection timing, the control means 31 sends an OFF signal to a cleaning solenoid 32 after a prescribed time elapse, and the pressure of the cleaning blade is released. In such a way, the number of times of the pressure release of the cleansing blade is decreased, and the contamination of the inside of a copying device can be prevented.

Title: Sample-hold circuit and linear codec circuit
Inventor: IINO YUKINOBU
IPC: G11C27/02
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To reduce an error voltage and to enhance sampling precision by using an amplifier inputting two signals of phases opposite to each other, holding voltages of respective signals at separate capacitors and sharing a reference voltage of these capacitors. SOLUTION: When a clock ϕ is a high level, and the clock/ϕis a low level, analog switches S1, S2, S4, S6 are turned on, and S3, S5 are turned off. Thus, a capacitor C1 is charged by the voltage Vin on a positive phase side that a signal voltage Vin is outputted from the amplifier 1. Further, on an opposite phase side, the capacitor C3 is charged with the voltage -Vin by an output of an inversion amplifier 2. When the capacitors C1, C3 are charged, though a rush current is caused, since the rush currents charging both capacitors C1, C3 are equal in size, and flow so as to cancel each other, the rush current doesn't flow into a reference point output amplifier 3.

Title: Output buffer circuit
Inventor: HASHIMOTO SUKEYOSHI
IPC: H03K19/0944
Filed: 1992-04-06
Abstract: PURPOSE:To reduce a source noise at a 'H' outputting time and to prevent an output terminal OUT from being in a floating state even when a whisker-like pulse occurs in an input signal and to stably perform a 'H' output. CONSTITUTION:When an input signal S is 'L' and the input signal R is 'H', the output side node N31 of an inverter 31 becomes ''H'' and an NMOS 41 is turned on and OUT becomes 'H'. Thereafter, the potential of the N31 is delayed by a delay means 32 and boosted by a boot strap circuit 33 and the NMOS 32 is turned on and current flows from source potential VCC through OUT. In such a manner, since 'H' is supplied to OUT gradually, the large current is prevented from flowing through OUT from the VCC at a stroke and then the source noise is reduced. Further, 'H' of OUT is maintained by the NMOS 41 even though the whisker-like pulse occurs in the S and 'H' is not outputted by the boot strap circuit 33.
