Title: Image forming device
Inventor: MURAMATSU MASANORI
IPC: G03G15/08
Filed: 1993-09-13
Abstract: PURPOSE:To output a multilevel image with stable density by deciding the operating condition of an image forming means based on the measured density of a sample image and detected toner concentration. CONSTITUTION:Respective color toner images with fixed density successively formed on a specified image forming condition are successively read by using a black toner concentration detecting sensor 600, and the read data is fed back to the image forming condition of each color. As to color toner such as yellow, magenta and cyan; reflected light quantity becomes larger than in the case of a photoreceptor drum 19 being a simple substance and output from the sensor 600 becomes larger as an area covering rate becomes larger and the density of an output image becomes higher. Meanwhile, as to black toner, the reflected light quantity becomes smaller than in the case of the photoreceptor drum 19 being the simple substance and the output from the sensor 600 becomes smaller as the area covering rate becomes larger and the density of the output image becomes higher. By using such relation, the density of the output image is accurately obtained based on the output from the sensor even in the case of the toner having different reflection characteristic.

Title: Method for determining and measuring resistance of resistance circuit including nonlinear element having polarity and wiring connection checker utilizing the same
Inventor: AOKI TAKANORI
IPC: G01R31/02
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To specify the resistance accurately by determining the difference between two voltages, when a current is supplied twice in the opposite directions to a circuit combining a resistor to be measured and two nonlinear elements having polarity. SOLUTION: At first, a current Ik is fed from pole L toward pole E. Voltage drop VL between both poles is the sum of the forward voltage VD1 of a first diode D1 and the voltage drop VRx of a resistor Rx to be measured. The current Ik is then fed from the pole E toward the pole L. Voltage drop VE between both poles is equal to the forward voltage VD2 of a second diode D2, and it is substantially equal to the VD1 because two diodes D1, D2 use identical components and operate with the same current Ik under the same ambient temperature. Since the difference in magnitude between the VL and VE is substantially equal to the voltage drop VRx of the resistor Rx to be measured, resistance of the resistor Rx can be determined accurately from the voltage VRx.

Title: Semiconductor integrated circuit
Inventor: ARAKI TATSU
IPC: H03F3/45
Filed: 1983-11-30
Abstract: PURPOSE:To expand an in-phase input voltage range of a differential amplifier circuit and to actuate the differential amplifier circuit normally even if the peripheral temperature is increased by connecting Darlington connection transistors (TR) between a differential TR and an input terminal. CONSTITUTION:The lower limit Vi cm(-) of the in-phase input voltage range is -25 deg.C and -0.3V even if the peripheral temperature reaches 150 deg.C, so that the differential amplifier circuit operates normally even if 0V is impressed to input terminals 2, 3. Since Darlington connection is applied to pnp TRs 6, 15 and pnp TRs 7, 16, input bias current becomes 1/beta as compared to an ordinary circuit. Provided that beta is the emitter-earth current amplification factor of the pnp TRs 15, 16 and the input bias current becomes about 1/100 of the ordinary circuit as its merit. Since the differential amplifier circuit is constituted so that a pair of TRs act as differential TRs, the in-phase input voltage range is expanded as compared to the ordinary differential amplifier circuit.

Title: Overvoltage overcurrent protection device
Inventor: OKAMOTO AKIHIRO
IPC: H01C1/14
Filed: 1995-09-05
Abstract: PROBLEM TO BE SOLVED: To break a circuit quickly, by separating a positive themistor away from a lead wire by a spring force of a coil-shaped spring when solder has been melted by the positive thermistor heating up itself in the event that an overvoltage or an overcurrent is applied to the positive thermistor. SOLUTION: A nickel-placed and a tin-placed electrodes are formed on both side faces of a positive thermistor (for example, 7ϕ×2.5tmm, Curie temperature: 90 deg.C, a resistant value: 12Ω), and lead wires 2, 3, of 0.5ϕ for example, are soldered to the electrodes with tin-lead eutectic solder. Then the lead wire 2 is soldered to a substrate 6 while a fixed end of a coil-shaped spring 5 is soldered to the substrate 6. Then the other end of the coil-shaped spring is hooked on and soldered to the lead wire 3. In this state, if a current, of 600V 40A, 600V 7A, or 600V 2.2A for example, is made to flow through the lead wires and the coil-shaped spring 5, the current flows through the positive thermistor, which heats up itself until it exceeds 183 deg.C, the melting point of solder, and the lead wire 3 is separated away from the thermistor, whereby a circuit is broken.

Title: Power switching device
Inventor: ISHIKAWA MASAYUKI
IPC: H01H33/16
Filed: 1988-09-14
Abstract: PURPOSE:To prevent the phenomena of voltage increase from being generated so as to prevent an apparatus from being dielectrically broken down, by arranging a shunt-reactor-switching gas circuit breaker and a high-temperature superconductor in series with each other to generate series resistance through the circuit when a high-frequency current is caused to flow through the circuit by reignition. CONSTITUTION:A high-temperature superconductor 30 which shows its superconducting state at the temperature of liquid nitrogen is arranged in series with a shunt-reactor- switching gas circuit breaker 2 and is used for switching a shunt reactor 1. While this breaker 2 is closed so that the shunt reactor is in connection with the circuit, a current flowing through both the superconductor 30 and the breaker 2 is for example several hundreds A, but that flowing therethrough in response to reignition at the separation of the shunt reactor will be several KA. In this case, the transition current of the superconductor 30 when it is converted from its superconducting state to normal conducting state is set to about 1000A. The superconductor 30 is therefore converted to its normal conducting state by the current flowing therethrough in response to the reignition, and its series resistance is inserted into the circuit; a reignition high-frequency current is quickly damped as a result.

Abstract: PURPOSE:To match a video picture with different size or density, etc., with a facsimile transmission picture and to attain the communication with other kinds of equipments by reproducing the video input screen subjected to broadcast standardization standards in a picture memory area in compliance with facsimile standards. CONSTITUTION:When the program of a CPU 7 is started and the operator selects the transmission of the still video pattern mode, the program sets a starting command to a CCU 10.
