IPC: B60G17/04
Filed: 1990-08-24
Abstract: PURPOSE:To reduce engine horsepower consumed for supporting a car body weight, by extending/contracting the 1st piston of a vacuum pressure cylinder by feeding oil pressure to a hydraulic cylinder as a car body jolts, and raising/ lowering a car wheel so that an unchanged car body posture may be retained. CONSTITUTION:Pushing down force F1 acts on the 1st piston 15 of a vacuum cylinder C due to atmospheric pressure flowing into an atmospheric pressure chamber 17, and a car body weight W is supported by this pushing down force F1. And when a car wheel together with a piston rod 25 is displaced up and down against a car body at the time of traveling on an uneven road surface, this car body jolting is detected by means of a sensor 33 and fed to a controller 32, and a control signal is outputted to a control valve 31. As a result, the 2nd piston 18 is contracted/extended by feeding the discharge pressure oil to a hydraulic cylinder D contraction side oil chamber 19 or extension oil chamber 20, and the 1st piston 15 is moved up and down through a rod 28, and on account of this, the retention of an unchanged car body posture is made by moving the car wheel up and down through the piston rod 25.

Title: Handy scanner
Inventor: HYODO MASATAKE
IPC: H04N1/107
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To obtain a uniform read reproduction image without uneven density by controlling a light source for lighting an original on the basis of a photoelectric conversion signal and correcting a change in the luminous quantity of the light source for lighting the original depending on a tilt of a scanner main body with respect to a face of the original. SOLUTION: In a tilt state K3 of a scanner main body, the luminous quantity of a reflected light in a reflecting plate and an original face 12 is deficient more than the luminous quantity of a reflected light when the scanner main body 7 is not tilted with respect to the original face resulting that a tilt sensing signal level L3 outputted from a line sensor section is higher than a signal level L1. A luminous quantity control section increases a current flowing to an original lighting LED light source on the basis thereof to compensate the deficiency of the luminous quantity of the reflected light. Furthermore, when a level of a sample-hold signal is lower than the signal level L3, it decreases the current flowing to the original lighting LED light source thereby decreasing the luminous quantity of the reflected light in the original face 12.  Thus, the luminous quantity of the reflected light in the original face 12 is controlled constant independently of the tilt of the scanner main body.

Inventor: KAI YASUAKI
IPC: G02B5/00
Filed: 1986-09-22
Abstract: PURPOSE:To obtain the titled plate which does not elute a dyestuff in a transparent resin and does not disperse it in said resin, thereby not reducing light transmittance,and is prevented to make the transparent resin completely opaque, even in case of using the plate for a long period by burying the resin which has <1.0 hydrogen bonding force and <=9 dissolution parameter in the through hole of the titled plate. CONSTITUTION:The titled plate provides a screen which is composed of a resin composition dyed to opaque by the dyestuff, and has partially the through poles. The transparent resin which has <1.0 hydrogen bonding force and <=9 the dissolution parameter is burried in said through holes. In case that the dyestuff having good compatibility with said resin is used, said dyestuff has tendency for eluting from the photosensitive resin composition, followed by diffusing in the transparent resin. So that, in order to prevent the elution of the dyestuff, the transparent resin material having less compatibility with the dyestuff is used. Said resin is exemplified by a UV curable epoxy acrylate, a thermocurable methylphenylsilicone and a hotmelt type modified polyethylene- vinylacetate copolymer, etc.

Filed: 1994-09-16
Abstract: PURPOSE: To suppress the difference between the pressure in a container and its peripheral hydraulic pressure by equipping the pressure controller with a 1st value and valve and a buffer tank which absorbs the pressure difference between the gas pressure in the container and outside hydraulic pressure. CONSTITUTION: The main tap 2 of a pressurized gas cylinder 1 is opened. Then the container 5, a pressure reduction valve 4, a pressure holding valve 9, and the buffer tank 11 are dipped in water. Then the pressure reduction valve 4 is opened corresponding to variation (increase) in the outside hydraulic pressure to supply gas into the container 5 and the pressure in the container 5 becomes equal to the circumferential hydraulic pressure; when they are settled, the supply of the pressurized gas from the pressure reduction valve 4 stops and the state wherein there is no pressure difference is held.  When the container 5, etc., is elevated next, the pressure holding valve 9 operates corresponding to variation (decrease) in the outside hydraulic pressure and the gas in the container 5 is discharged through the pressure holding valve 9, so that the pressure difference between the pressure in the container 5 and the hydraulic pressure becomes zero. Then when the pressure difference between the outside hydraulic pressure and the pressure in the container 5 is within a certain set range, variation in the pressure in the container 5 corresponding to the pressure difference is absorbed by the expansion or contraction of the internal tank in the buffer tank 11.

Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To make a stress resulted from the unevenness of adhesive applied state difficult to be generated, and minimize the generation of noise by fixing a pyroelectric element on a substrate with a conductive adhesive having a pencil hardness after curing of a specified value. SOLUTION: In this pyroelectric infrared ray sensor, a conductive adhesive for bonding a pyroelectric element 2 to a substrate 3 has a pencil hardness after curing of 4B or less. As the conductive adhesive, rubber, silicone, urethane, and polyolefin adhesives, or mixtures of these epoxy resins are used. Thus, even when the adhesive applied state is uneven, no noise output is generated without adding a stress to the pyroelectric element 2. The stress resulted from the difference in thermal expansion coefficient between the pyroelectric element 2 and the substrate 3 by the ambient temperature change can be also moderated by the adhesive of the bonding part.
