Inventor: KIDO TOMOYUKI
IPC: B62D6/00
Filed: 1990-06-28
Abstract: PURPOSE:To improve turning ability and running stability at steering rear wheels and front wheels in same phase by delaying steering beginning of rear wheels against that of front wheels, and instituting the larger in the delay time the higher in steering speed. CONSTITUTION:As for control at steering rear wheels 4 in the same phase as front wheels, a delay time corresponding to steering angular speed and vehicle speed at the time of running is read from a control map in real time, and steering of the rear wheels 4 is delayed against steering of the front wheels 3 based on it. Hereby, at steering, a vehicle is quicly turned around, movement after turning is stabilized, and control stability at steering is improved. In this case, the delay time of steering of the rear wheels 4 against steering of the front wheels 3 is controlled according to the steering angular speed, when the steering is quickly operated, the delay time is instituted larger, and hence high controllability of the vehicle favorably responsing to steering operation is attained.

Title: Preheater for diesel engine
Inventor: KATOU YOUJI
IPC: F02P19/02
Filed: 1979-12-28
Abstract: PURPOSE: To decrease the rise-up time of electric conduction temperature for glow plugs in a preheater, by providing a resistor, used at the time of starting an engine, consisting of the system from barium titanate with a positive resistance-temperature coefficient and a rapid increase of the resistance value at specific temperature.  
     CONSTITUTION: When a switch 2 is turned on to close a preheating contact 2a, an electric current flows in a coil 3b of a glow plug relay 3 from a battery 1 to generate attracting force in the coil 3b and close a normally-open contact 3a. A starting resistor 7, having a positive resistance-temperature coefficient, is provided with a small value of its resistance to accordingly preheat glow plugs 6 by an electric current at a sufficient level. If the glow plug 6 is fully preheated, the resistance value of the resistor 7 is rapidly increased and the current flowing in the glow plug 6 is rapidly decreased. The current flowing in the glow plug 6 at the time of steady-state operation can be determined almost by the value of a resistor 8.

IPC: G03G5/14
Filed: 1983-09-19
Abstract: PURPOSE:To obtain an image of high quality by applying toner having the opposite polarity of a charge given to the surface of a photosensitive body over the entire surface of the photosensitive body, and performing image exposure and transferring the toner whose attracting force is weakened by the exposure to transfer paper by a counter electrode applied with a voltage having the opposite polarity. CONSTITUTION:The cylindrical photosensitive body 30 formed by laminating a light transmittive substrate 11, light transmittive conductive layer 12 and a photoconductive layer 13 from inside is rotated counterclockwise. A plus charge is supplied to the surface of the photosensitive body by an electrostatic charger 31, and negative toner is applied by a toner coating device 32. Then, an image exposing device 33 irradiates the photosensitive body 30 with light from inside to form an image. The toner whose attracting force is weakened by the image exposure is transferred to transfer material 37 as normal paper through the operation of a plus DC voltage applied to the counter electrode 34. The image on the transfer material 37 is fixed at a fixation part 38 and the material is discharged. The toner remaining on the surface of the photosensitive body 30 is collected with a brush 35d by removing its charge by a destaticizing lamp 35a and returned to the toner coating part 32. Consequently, the image with high resolution is formed at a high speed with less energy.

Filed: 1994-07-25
Abstract: PURPOSE:To suppress the voltage drop of a power supply voltage even when A/D conversion is continuously performed by stopping the conversion processing of the sampled analog measured value of a second time to a digital signal until the declined level of the power supply voltage to be supplied to a microprocessor recovers to be more than a prescribed level. CONSTITUTION:The microprocessor MP operates an A/D conversion part H and performs the sampling of the analog measured value from a temperature detection part D continuously for two times. The decline of the power supply voltage at the time of the A/D conversion of a first time is detected in a voltage detection part K and the voltage detection part K outputs a detection signal to the microprocessor MP. The microprocessor MP discriminates the detection signal and stops the conversion processing of the sampled analog measured value of the second time to the digital signal until the declined level of the power supply voltage to be supplied recovers to be more than the prescribed level. Then, when the power supply voltage level recovers to be more than the prescribed level, the A/D conversion of the second time is performed by the A/D conversion part H.

Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To completely eliminate noise component contained in magnetically detected signals. SOLUTION: The apparatus resolves magnetically detected original signals from a SQUID sensor 1 into dependent component signals for each magnetic source according to ICA process by a magnetic-signal resolving station 4. It is provided with a constitution that judges whether each dependent component is noise component or not based solely on the state of the component at a noise-component eliminating station 5, and restores magnetically detected signals from remaining dependent non-noise components after removal of what has been judged as a noise component at a magnetic-signal restoring station 6. The signals obtained from the SQUID sensor 1 are sufficient enough to eliminate the noise component contained in magnetically detected signals and to permit separate analysis of each component without need of providing a proper magnetic sensor for noise detection.

Filed: 1988-07-12
Abstract: PURPOSE:To make a self-oxide film of an N-type GaAs contact layer work as a buffer layer of stress due to a difference in thermal expansion coefficient of the N-type GaAs contact layer and a nitride film by interposing the self-oxide film between the N-type GaAs contact layer and a nitride film as a diffusion mask. CONSTITUTION:A GaAs self-oxide film 11 is formed on a surface of TJS-LD epitaxial growth layer from hundreds of Angstrom  to thousands of Angstrom . A nitride film (SIN) 9 is formed in stripes as a diffusion mask. Then Zn 10 is diffused using the nitride film 9 as a mask until it reaches the GaAs substrate 1 to form a P-type layer 6. The nitride film 9 is eliminated entirely, and a P-electrode 8 and an N-electrode 7 are formed on the side of the P-type layer 6 and the N side, respectively. A P-N junction of an N-type GaAs contact layer 5 is eliminated and cleaved to form a chip of a laser diode. Since the self-oxide film 11 of GaAs is composed of the same elements as an N-type GaAs contact layer 5 between the layer 5 and the nitride film 9, a stress to the N-type GaAs contact layer 5 is reduced.
