Title: Protection circuit for signal compensation
Inventor: UCHIKAWA SETOMI
IPC: H04J3/00
Filed: 1990-07-18
Abstract: PURPOSE:To simplify the circuit and to reduce the circuit scale by storing a multiplexed signal to a memory sequentially, reading the signal and adding the signal to compare coincidence/dissidence and using a selector circuit for bit protection. CONSTITUTION:Plural input signals 101 are inputted to a multiplexer 1, in which the signals 101 are multiplexed by using a timing signal from a control section 3 and the result is stored in a memory 2. Three signal bits each are inputted to an adder section 4, in which they are added. When the three bits are coincident, an output of the adder section 4 goes to logical H. An output of the adder section 4 is inputted to a demultiplexer 7 via a selector circuit 5 and stored in a memory 6 simultaneously. When they are dissident, preceding newest correct signal bits having already been stored in the memory 6 are selected and inputted to the demultiplexer 7 and stored simultaneously in the memory 6. The signal demultiplexed by the demultiplexer 7 is an output signal 103.

Title: Driving method for liquid crystal element
Inventor: OOTA SUNAO
IPC: G09G3/36
Filed: 1986-08-13
Abstract: PURPOSE:To perform the temperature compensation of a liquid crystal element which uses ferroelectric liquid crystal substantially without any problem by adjusting both the with of driving pulses and a driving voltage and carrying out the temperature compensation. CONSTITUTION:Both the driving pulse width and the driving voltage are adjusted to vary the driving pulse width greatly in a low temperature range and reduce variation width in a high temperature range so that the driving pulse width is short in the high temperature range. The lower limit of the driving pulse width is is set two-four times the time constant determined by the wiring resistance of the liquid crystal element and the output impedance of a driving circuit. Further, the driving voltage is varied greatly in the high frequency range and while the variation width is reduced in the low temperature area, the driving voltage is made low in the high temperature range. Thus, the driving pulse width is made long in the low temperature area to evade a rise in the driving voltage and while the driving voltage is lowered in the high temperature range, the lower limit of the driving pulse width is provided to evade the generation in optical characteristics among respective picture elements due to the rounding of an applied waveform.

Title: Wire bonder
Inventor: ENDO MITSUHIKO
IPC: H01L21/60
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To prevent a fine recessed part from being formed owing to the sticking of a cut fragments by increasing the width of the groove of an wedge from both end parts to the intermediate part and decreasing the depth of the groove from both end parts to the intermediate part. SOLUTION: The wedge 8 is so formed that the width of the plane shape of the groove 9 formed in the reverse surface of a long leg piece 8a is increased from both ends 9a and 9b to the intermediate part 9c and the depth of the groove 9 viewed from the side section is decreased from both end parts 9a and 9b to the intermediate part 9c. Both end parts 9a and 9b of the groove are narrow in opening width, but set deep, so a wire which is pressed at the groove intermediate part 9c and extruded to both end parts 9a and 9b decreases in outward pressure, so sufficient gaps can be secured between both end parts of the groove and the pressed wire 7, contact pressure to the wire 7 is small, and the sticking of materials of the wire 7 is suppressed. Consequently, the formation of a fine recessed part due to wire sticking can be eliminated.

Title: Bipolar mos current detection circuit
Inventor: KASHIMURA MASAHIKO
IPC: G11C17/18
Filed: 1989-07-25
Abstract: PURPOSE:To detect the micro change of a current at high speed by generating the change of a voltage with a resistance element inserted between first and second transistors, and detecting it with a differential amplifier comprised of third and fourth transistors. CONSTITUTION:When a row selection signal X2 goes to an H level, the N- channel MOSFET 12 of a ROM cell is turned on, and the current flows from a power source 1 via an NPN type bipolar transistor (Tr) 3, a resistor 14, a Tr 4, and a MOSFET 8. Therefore, voltage drop occurs at both ends of the resistor 14, and the potential of a connecting point 13 drops. The output terminal 19 of a differential amplifier circuit comprised of Trs 5, 6 and a power source MOSFET 7 goes to a low level when the voltage of the connecting part 13 is less than preset potential D to be applied on the base of the Tr 6, and when the signal X2 goes to the low level and the potential of the connecting point 13 rises and exceeds the preset potential D, the potential E of the output terminal 19 starts to go to the H level. Since the change of the potential of the connecting point 13 is low, delay time is remarkably shortened, which enables the readout of a ROM to be performed at high speed.
