Title: Image forming device
Inventor: MIYAMOTO TAKESHI
IPC: G03G15/00
Filed: 1987-08-25
Abstract: PURPOSE:To favorably maintain an image forming state by detecting a developer sticking state on the surface of a photosensitive body and altering the image forming conditions of the developer according to the detected result. CONSTITUTION:Forming the image is executed by turning off a blank lamp for a specified time in the midst of warming-up after turning on a power source and the developer is made to be sticked to the photosensitive belt 2 and an intermediate belt 8, then the sticking state of the developer is detected by a density sensor 13. When an error occurs between the detected value of the density sensor 13 and a set value A, a developing potential B stored in a memory area concerning the respective colors of the developer is increased or decreased so as to make an output from the density sensor 13 coincide with the set value A. In other words, a charger is driven so that the developing potential stored in the memory area can be realized at the time of copying process. Thus, the image forming state can be favorably maintained.

Title: Two-story parking system
Inventor: KOJIMA KINSAKU
IPC: E04H6/06
Filed: 1993-08-03
Abstract: PURPOSE:To safely park automobiles by turning upper and lower parking stands thus moving the front side of each stand vertically, flattening the parking face of the upper parking stand, enabling the lower parking stand to be curved, and making a portion in front of their middle portion horizontal. CONSTITUTION:To use a parking stand 1, it is vertically turned about a horizontal rotating shaft 17 as a hydraulic cylinder 18 contracts; then the lower surface of a parking stand 2 abuts the bottom surface 3a of a pit 3 and the front end 22 of the stand 1 abuts a road G; thereby a stopper sensor 19 is operated to stop the hydraulic cylinder 18; then a vehicle 4 on the road G is moved onto the parking stand 1. To use a parking stand 2, the parking stands 1, 2 are turned upward by expansion of the hydraulic cylinder 18, a front stand 2a is hoisted using a connecting rod 14, and when the front end 21 of the stand 2 aligns with the road G the sensor 19 is operated to stop the cylinder 18; a support shaft 12 is also moved upward. The inclination angle of the entire parking stand 2 is therefore decreased to make effective use of the pit space and to eliminate the need for boring deep in the ground, thus facilitating construction.

Title: Semiconductor wafer manufacturing device and method
Inventor: FURUKAWA HIROSHI
IPC: H01L27/12
Filed: 1993-08-04
Abstract: PURPOSE:To enable the high flatness of a normal silicon wafer or bonding SOI wafer to be realized. CONSTITUTION:An electrostatic capacitor type thickness measuring instrument is used for measuring the thickness per 3.8mmphi angle of ground silicon wafer 1 to store the thickness data on the measured positions.

At this time, the oxygen jetting position and the time are controlled according to the measured data. Next, when partial oxidation of the thickpart 1a is finished, the power supply of the heater 2 is cut off to cool down the silicon wafer 1 at normal temperature and then the wafer 1 is immersed in a diluted hydro- acid fluoride to be cleaned up for removing an oxide film. Furthermore, substituting for the oxidizing and cleaning steps, the thicker part 1a only may be jetted with an etchant.

Filed: 1986-09-10
Abstract: PURPOSE:To easily obtain a curved line smoothly connecting a dot string by obtaining a tangent vector at each point of the dot string with the aid of continuous three or five points. CONSTITUTION:An arc CAR passing by three continuous points Pi-1, Pi and Pi+1, all of which are given discretely, is obtained, then the tangent vector tangent to the arc CAR at the point Pi in the center is obtained. Similarly the tangent vector Pi-1 at the point Pi-1 is obtained. With the aid of the position vectors Pi-1 and Pi, and the tangent vector Pi-1 and Pi at the points Pi-1 and Pi, the two points Pi and Pi+1 are spline-interpolated to obtain a coordinate value Si(t) (t: 0-1 calculated by 0.1). Finally the curved line smoothly connecting the two points Pi and Pi+1 is obtained. Hence onward all two continuous points given discretely are interpolated similarly to obtain the curved line connecting the dot string.

Title: Light guiding type display device
Inventor: SONEHARA TOMIO
IPC: G02B6/04
Filed: 1988-08-26
Abstract: PURPOSE:To reduce the length of optical fibers used for the display device and to prevent the deterioration in the displaying quality by intricately arranging the optical fibers optically coupling an optical shutter with a displaying surface. CONSTITUTION:Each block 101 constituting a screen is intricate with another at the picture outputting end of a light guiding body 103 which becomes the screen and a liquid crystal display body is used for an optical shutter 104 which is a picture forming means and has a picture inputting end 102. Namely, on the light emitting side, fiber bundles 201 respectively composed of 30 sheets (each sheets is composed of 180 pieces of fibers 202) are alternately shifted so that their arrangement on the light emitting surface can be intricate with each other and the surface 203 of incident having a rectangular cross section corresponds to the displaying surface of the optical shutter. Therefore, when the information made incident to the fibers from the optical shutter side is reversely shifted in accordance with the shifted state on the light emitting end, the displayed information becomes normal. Thus the visibility of the boundary among blocks can be lowered and a light guided type display having a high uniform displaying quality can be made.

Accordingly, a state which can produce a failure can be predicted before the failure actually occurs. Therefore, a preventive measure can be taken and the occurrence of power failures, etc., can be prevented.

Abstract: PURPOSE:To obtain a compound having the effect of suppressing wax deposition from a petroleum middle distillate fuel oil at low temperatures by reacting an amine with an amide prepared by reacting an alpha-olefin/maleic anhydride copolymer with a dialkylamine. CONSTITUTION:The objective agent comprises a compound prepared by reacting R3-NH2 (wherein R3 is a 2-8C aliphatic hydrocarbon group) or an alkali metal with an amide prepared by reacting a copolymer of an average molecular weight of 1000-10000, prepared by copolymerizing a 12-24C alpha-olefin or an inner monoolefin with maleic anhydride, with R1-NH-R2 (wherein R1 and R2 are each a 1-24C aliphatic hydrocarbon group). When this agent entirely consists of the above compound, it is very effective in suppressing the wax deposition at the deposition initiation temperature or near, but the extent of suppression of wax deposition decreases with a falling temperature. However, when it comprises a mixture of this compound with EVA of a vinyl acetate content of 10-40wt.%, it can persist its effect even at lower temperatures owing to the synergistic effect.

IPC: H01M4/20
Filed: 1981-12-24
Abstract: PURPOSE:To increase life and performance of a lead-acid battery by using barium sulfate which produces by the reaction of barium hydroxide with dilute sulfuric acid when a cathode paste for the lead-acid battery is kneaded, as anti-shrinkage agent for a cathode plate. CONSTITUTION:When a cathode paste for a lead-acid battery is kneaded, a barium hydroxide solution is put into the paste to uniformly disperse barium ion on the surface of lead oxide powder and in the water. When the kneading is finished, dilute sulfuric acid is added to form uniformly fine barium sulfate in the paste.
