Title: Electrophotographic printing device
Inventor: NAGANUMA HISASHI
IPC: G03G15/09
Filed: 1985-04-11
Abstract: PURPOSE:To use >=1 developer storage tanks and to form plural developing units integrally with the tanks by forming >=2 partitioned chambers where developers of different color are charged in the axial direction of a photosensitive drum and providing a magnet roller to each chamber individually. CONSTITUTION:When a partial two-color print is made in one sheet, electrostatic latent images are formed on the peripheral surface of the photosensitive drum 1 within ranges corresponding to the sizes of developing areas A and B of a developing device 5 and toner particles of different toner which stick on the peripheral surface of a sleeve roller 8 are attracted to the electrostatic latent images by magnet rollers 7a and 7b, thereby developing those latent images physically with the toner particles of different color. Then, each toner image is transferred to cut paper 21 by a transfer charger 12 and fixed on the cut paper 21 by a fixing device 14, and the printing operation is completed. The magnet rollers 7a and 7b are provided to the respective chambers A and B individually and exert no influence upon the adjacent chambers, so toner particles of two colors are never mixed with each other.

Title: Optical disk reproducing device
Inventor: SUNAKAWA RYUICHI
IPC: G11B7/005
Filed: 1988-03-30
Abstract: PURPOSE:To improve jitter and to lower error rate by correcting the amplitude of a reproducing signal by a correcting means and making a pulse width equal to a reference pulse width when the pulse width is different from the reference pulse width. CONSTITUTION:A reproducing signal Sp from an optical pickup is supplied to a comparator 3 which is a component of a waveform shaping means through an RF amplifier 1 and the series circuit of an amplitude correcting circuit 2 and made into a pulse string signal. An output signal Scmp of the comparator 3 is supplied to a length comparator 4 which is a component of a pulse width comparing means 100, and is supplied also to a reference pulse generator 5. When the pulse width of a pulse outputted from the waveform shaping means by corresponding to a bit and land of a prescribed length is different from the reference pulse width, the amplitude of the reproducing signal is corrected by the correcting means and the pulse width is made equal to the reference pulse width. Thus, the jitter is improved and the error rate can be lowered.

Title: Nonvolatile memory cell
Inventor: TAKAHASHI KAZUKIYO
IPC: G11C14/00
Filed: 1981-05-22
Abstract: PURPOSE:To make high-speed write and to read operations possible without increasing the number of elements per memory cell, by using a magnetoresistance element as a load element and arranging a magnetic thin film for each of a pair of lead wires. CONSTITUTION:Magnetoresistance elements which change resistance values in accordance with directions and magnitudes of applied magnetic fields are used as load elements 20 and 21. Magnetic thin films 22 and 23 are arragned, and the magnetization of the thin film 22 is inverted by the magnetic field, which is generated by a write current of a lead wire 4, when information different from stored contents is written. The magnetization of the thin film 23 is inverted by the magnetic field generated by a current flowed to a lead wire 5. Magnetic fields generated by thin films 22 and 23 acts upon elements 20 and 21 to change their electric resistances, and the relation between thier electric resistances in magnitude is reversed. Since stored contents are stored as magnetization directions of thin films 22 and 23, they are held even if the power supply is broken. The magnetization of thin films is inverted by rotation, and therefore it is in high-speed.

Abstract: PURPOSE:To suppress a speed change shock with a double engaging condition transferred to an optimum condition by a feedback by detecting torque of an output shaft in an automatic transmission and, in accordance with the detection, correcting an engaging speed of a clutch or a brake in an engaging side. CONSTITUTION:A central control unit (CPU) inputs a signal of each sensor, switch 23 to 27, 36, calculating torque with an output value of the acceleration sensor 36 serving as a torque change value of an output shaft in an automatic transmission. In accordance with the calculated torque, an engaging speed of clutches C0, C2 and brakes B0 to B2 in an engaging side is corrected by a tilt correction processing routine duty-ratio controlling control solenoid valves 28 to 32. Thus automatically correcting the engaging speed of the clutches or brakes in the engaging side when a double engaging condition is not suited in a speed change process, the double engaging condition is transferred to an optimum condition by a feedback, and a feeling at the time of running can be improved by decreasing a shock in the speed change.

Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a starting signal generator for a vehicle which can reduce the power condumption of a battery, and avoid the power exhaustion of the battery. SOLUTION: Switches SW1-SW4 are low side switches. If they are turned on, the input signals of pulse generators 51-54 are switched to high level signals through respective inverters 61-64. In response to the switching, pulse signals including pulses with specified time widths are outputted from the pulse generators 51-54 to a NAND 3 through inverters 41-44. In other words, when at least one of the switches SW1-SW4 is turned on, a pulse with a specified time width is outputted from the output terminal 3a of the NAND 3. A CPU 2 monitors an interrupt terminal 2a and, if that pulse is inputted, switches a power supply state from an unnecessary current cut-off mode to a normal mode.

Filed: 1985-04-15
Abstract: PURPOSE:To execute easily rounding by providing an arithmetic circuit for selecting a rounding object bit by difference of accuracy and detecting an overflow of a mantissa part, and updating an exponential part. CONSTITUTION:When executing the rounding, the contents of a register 1 are processed by passing through an arithmetic circuit 3 and a mask circuit 4, and a result is stored again in the register 1. When an accuracy register 2 designates a single accuracy, a selecting circuit 35 selects a value of a bit 32, and a selecting circuit 36 selects '0'. On the other hand, when a double accuracy is designated, the circuit 35 and the circuit 36 select a carry output from the bit 32, and a value of a bit 64, respectively. In this case, when the register 2 designates a single accuracy, only selectors 44, 45 select '0'. Also, when a carry output from the uppermost bit of a mantissa of the circuit 3 is '1', a selector 42 selects '1'. In this way, an exponential part can be updated by the arithmetic circuit by selecting a rounding object bit by a difference of the accuracy and detecting an overflow of a mantissa part.
