Title: Analog type meter
Inventor: HASEGAWA YOSHIHISA
IPC: G01P3/48
Filed: 1982-06-30
Abstract: PURPOSE:To eliminate the deflection of a pointer even in a region where the frequency of an input signal is low by multiplying the frequency of the input signal and setting the set current value in a driving circuit with a constant current pulse at half of the specified value. CONSTITUTION:The input pulse signal In which is supplied to an input terminal 1 and has the frequency proportional to the number of revolutions of an engine is multiplied with a frequency multiplier 5 and is then inputted to a monostable multivibrator circuit 2. The signal of the constant pulse width of which the period is made half of the period of the signal in the prior art is inputted from a driving circuit 3 with a constant current pulse wherein a current set value is set at half of the specified value to an analog ammeter 4. Thus, the pointer of the ammeter 4 indicates exactly the number of revolutions of the engine without deflection even if the frequency of the input pulse signal is low.

Title: Graphic data converter
Inventor: KANEKO MASAHIKO
IPC: G06T11/80
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To eliminate the conventional time and labor for performing manual correction for the separated end parts of a two-dimensional graphic by calculating the reference point of a vector graphic from an intersection after rounding and generating the vector graphic data of second accuracy. SOLUTION: The graphic data of single accuracy before conversion are read and whether or not the read data 4 are circular arc data is discriminated. In the case of the circular arc data, the coordinates of a start point and an end point are obtained, the circular arc data are regenerated based on them, rounding is performed so as to bring the end point of two line segment data which are the data 4 before the conversion and the end point of the circular arc data into contact and the graphic data 5 of double accuracy are generated. Also, in the case that the data 4 are the line segment data, for the start point and end point coordinates of the taken-out line segment data, rounding is performed within the range of the digit of the single accuracy and the coordinate values of the start point and the end point after the conversion are obtained.  Thus, the coordinates of the end points of the two line segments and the start point and end point of the circular arc data are completely automatically matched.

Title: Water leakage detecting agent and water leakage detecting method
Inventor: KANEKO TADAAKI
IPC: G01M3/06
Filed: 1984-06-04
Abstract: PURPOSE:To use the titled detecting agent at the time of a pressureproof test of a structure, to make it safe at the time of a high pressure test, too, to cause no danger for scattering fragments of the structure, and to detect visually, exactly and easily leakage of a very small quantity of water, as well. CONSTITUTION:A water leakage detecting agent consisting of about 60wt% soda bicarbonate powder, about 30wt% citric acid powder, and the balance powder soap is used. Also, the inside of a closed structure 1 of a cubical box shape is filled with water by operating a hydraulic pump 4. Subsequently, a water leakage detecting agent is applied to an optional part of the structure 1, to the whole surface if necessary, and the pressure is raised to a desired test pressure by the pump 4. In this case, if remarkable defects such as cracks, etc. running to the outside and inside of the structure exists in the structure 1, pressurized water jets out. The jetted water reacts to soda bicarbonate and citric acid for constituting the components of the water leakage detecting agent, generates carbon dioxide, and on the other hand, powder soap is melted in water and generates soap foams, and a water leakage part can be detected visually by both of them. Also, since the pressurized water is used, scattering of fragments caused by breakdown of the structure 1 is prevented by stopping the pressure in a state that water leakage exists.

Filed: 1984-06-04
Abstract: PURPOSE:To propagate images of high resolution by using fiber strands different in numerical apertures to form a bundle fiber and making adjacent fiber elements different in numerical aperture from each other and reducing output/input of light between fiber elements to improve the insulating capacity between fiber strands. CONSTITUTION:Many fiber base materials 12 different in numerical aperture are prepared and are so bundled irregularly that numerical apertures of adjacent fiber base materials 12 are different from each other as much as possible. They are then inserted to the glass tube 13' and are collapsed and subjected to wire drawing while heated at a prescribed temperature by a heater 14. Parts other than both ends of the glass tube 13' formed with an acid solute glass are eluted with an acid and are removed to produce a flexible bundle fiber 11 whose both ends are bound and fixed. When the light is leaked from a fiber element 12a having a large numerical aperture, the proportion of the light taken into a fiber element 12b is reduced because the fiber element 12b having a small numerical aperture is adjacent to the fiber element 12a.

Title: Supporting body for electrophotographic photoreceptor, its production and electrophotographic photoreceptor
Inventor: SENBA NAOYUKI
IPC: G03G5/10
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To prevent an interference fringe pattern from occurring on the image even in the case of using coherent light as exposing light by forming an anodic oxide film on the surface of base substance made of aluminum-based alloy and further performing dry blast processing to the surface. SOLUTION: After the anodic oxide film is formed on the surface of the base substance 1 made of the aluminum-based alloy and further the substance 1 is attached to a rotary supporting body 4, the dry blast processing is performed to the surface of the anodic oxide film while the substance 1 is rotated centering a cylinder shaft. It is suitable to use particles whose average particle size is <=15 μm as grinding and sweeping material in the dry blast processing, and also suitable to use alumina and SiC as the material thereof. The surface of the supporting body for a photoreceptor is made a rough surface by the dry blast processing, so that light scattering property is imparted to the surface.  Therefore, interference caused between light made incident on the photoreceptor and multiple reflected light on the surface of the supporting body is restrained, whereby the interference fringe pattern does not occur on the image. In such a case, it is desirable that the cycle of ruggedness is repeated on the surface of the base substance in a state where maximum height Rmax is <=2 μm and its interval is equal in one direction.

IPC: G03F7/038
Filed: 1981-07-23
Abstract: PURPOSE:To obtain a fine pattern of high accuracy for manufacturing an integrated circuit element, etc. by irradiating a film of a high energy beam sensitive high molecular compound as a resist with high energy beams while heating so as to increase the sensitivity. CONSTITUTION:A film of a negative type high energy beam sensitive high molecular compound expressed by the formula (where R is H or CH3, X is halogen or methyl halide, (m) is an integer, and (n) is 0 or an integer) is formed by coating and irradiated with high energy radiation such as electron beams or ion beams while heating at >=50 deg.C, forming a pattern. As the temp. is raised, the sensitivity is increased. For example, in case of chloromethylated polystyrene, to attain the same residual film ratio the quantity of irradiation at 95 deg.C requires about 60% of that at 25 deg.C. The resolution is maintained, the dry etching resistance is not changed by raising the irradiation temp. from 25 deg.C, and a fine pattern can be formed accurately.
