Title: Constant current power supply for ic-formed electronic circuit
Inventor: FUKUTOME FUJITOU
IPC: G05F3/22
Filed: 1987-10-02
Abstract: PURPOSE:To supply a stable constant current in spite of variation in a power supply voltage and a change in a peripheral temperature by reversing the polarity direction of the base-emitter voltage of a compensating transistor (TR) against that of the base-emitter voltage of a TR in 1st branch. CONSTITUTION:When the peripheral temperature is changed, the positive/ negative voltage of power supply in the 1st branch is stabilized by the constant voltage VBGR of a temperature compensating reference voltage generating circuit 4, so that variation in a reference current Io due to a change in the peripheral temperature of the base-emitter voltage VBE2 of the reference TR 2 is the 1st branch 1 goes the cause of a problem. About the problem, a change in the base emitter voltage VBE2 of the reference TR 2 due to the peripheral temperature is canceled by a change in the base-emitter voltage VBE1 of the compensating TR 5 because the polarity direction of the base-emitter voltage VBE2 of the reference TR 2 is reversed from that of the base-emitter voltage VBE1 of the compensating TR 5. Consequently, a stable constant current can be supplied in spite of a change in the peripheral temperature.

Title: Active matrix type liquid crystal display device
Inventor: ASAI YOSHIHIRO
IPC: G09F9/30
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To provide an active matrix type liquid crystal display device which is free from the occurrence of image quality defects even if alignment layers are partly peeled without adversely affecting its characteristics. SOLUTION: Even if a disconnection arises in the wiring portion of a signal line of aluminum, the wiring of a protective layer 14a of ITO exists in the disconnected portion and, therefore, the disconnection does not occur. The degradation in the yield occurring in the disconnection of the signal line may be suppressed. At the time of forming a source electrode 13S and a drain electrode 13D and the protective layer 14a on these source electrode 13S and drain electrode 13D, the layer may be used as an etching stopper. Even if minor mask alignment occurs, the simultaneous patterning of the source electrode 13S, the drain electrode 13D and the protective layer 14a is made possible and, therefore, the source electrode 13S and the drain electrode 13D may be surely coated by the protective layer 14a. The self-alignment by the protective layer 14a is possible as well.  The characteristics of a thin-film transistor is thus made constant.

Title: Call signal detection circuit
Inventor: NAKANISHI TADASHI
IPC: H03K5/04
Filed: 1986-10-20
Abstract: PURPOSE:To supply a pulse signal sufficient in width even for a call signal of square form to a counter circuit by adding a 2nd resistor and a 2nd capacitor to a call signal detection circuit. CONSTITUTION:The resistor 3 and the capacitor 4 are added to the call signal detection circuit. In case of the call signal formed as a square wave, a current flowing through a current limiting resistor 2 is differentiated by a DC block capacitor 1 and a DC limit resistor 2 to form a narrow pulse waveform. Since the capacitor 4, the current limiting resistor 2 and the resistor 3 act like a low pass filter to a current flowing through a photocoupler 5, in designing the constants to pass through the fundamental wave component only, the current waveform flowing to the photocoupler 5 and a reverse voltage protection diode 7 approaches a sinusoidal wave. Thus, the waveform appearing at the output of a photodetection section of the photocoupler 5 has a sufficient width to drive the counter circuit.

Title: Fixing device
Inventor: FUJIWARA TORU
IPC: G03G21/00
Filed: 1992-08-26
Abstract: PURPOSE:To eliminate faulty fixing and to prevent the curl of paper in a fixing device. CONSTITUTION:A thermistor 23 detects the surface temperature of a fixing roller 151 and outputs a temperature detection signal to a CPU 21 through an A/D converter 25. Based on the signal, the CPU 21 controls the heat generation of a heater 153 through a heater driving circuit 22. The paper is carried in a state where it is interposed between the fixing roller 151 and a backup roller 152. The calorific value of the heater 153 is decreased at the leading edge part and the trailing edge part of the paper. By restraining a water amount vaporized from the leading edge part and the trailing edge part of the paper, the curl of the paper is prevented. Since few toner images are formed at such parts, there is no trouble that the faulty fixing occurs because of the lowering of fixing temperature.
