Title: Ignition timing control of engine
Inventor: TAKEDA YUUJI
IPC: F02P5/15
Filed: 1983-01-26
Abstract: PURPOSE:To prevent the fluctuation of the igniton timing under an extremely low revolution of the engine by a method wherein an ignitor is put ON at first predetermined crank angle before an upper dead point and the ignitor is put OFF at second predetermined crank angle before the upper dead point under the low revolution of the engine. CONSTITUTION:When the revolving number of the engine detected by an engine revolution number sensor 32, is higher than a predetermined revolution number, a fuel injection time and the timing of ON, OFF of the ignitor are controlled based on the revolution number and the load of the engine. When the revolution number of the engine is up to the predetermined revolution number, the fuel injection time is determined in accordance with only a cooling water temperature sensed by a sensor 24 showing the operating condition of the engine and the ignitor 28 is put ON at the first predetermined crank angle of 60 deg., for example, before the upper dead point of the engine while the ignitor 28 is put OFF at the second predetermined crank angle of 30 deg., for example, which is nearer to the upper dead point, to ignite the engine. According to this method, the ignition may be effected surely at the predetermined crank angle and stable operation may be effected.

Inventor: UGAJI MASAKATA
IPC: H04R31/00
Filed: 1984-01-24
Abstract: PURPOSE:To make a diaphragm suitable to a speaker by heating a heat foaming agent of an edge member at a foaming temperature and foaming it, by forming blank of a diaphragm and the edge member into solid structure to forming a flat surface without an edge. CONSTITUTION:A base number applied with a heat foaming agent 16 is cut into a prescribed width and depth and formed into flat members 20. A pair of flat members 20 is placed so that the surface applied with a heat foaming agent 16 is facing each other. Then four edge members 14 with the precribed dimensions are stored in a rectangular groove 18 of a forming mold 17 in the condition in which the surfaces applied with the heat foaming agent 16 are along the end face so that they can be constant with the end face. Then the members 20 and 14 stored in the mold 17 are heated at the prescribed foaming temperature. The heat foaming agent applied to the members 20 and 14 begins to start foaming, fills in a space enclosed by the members 20 and 14; therefore they are bound each other, solidified and a flat diaphragm can be formed.

Title: Colored image displaying device
Inventor: KADOWAKI HIDEJIRO
IPC: B41J2/325
Filed: 1988-01-22
Abstract: PURPOSE:To repeatedly display a sufficiently clear colored image on a film for display by giving magnetism to fluidic ink positioned on the upstream side and providing a magnet for attracting the ink on the back of the film at the ink transferring location on the downstream side. CONSTITUTION:Fluidic inks 102 and 202 are moved by means of ink moving means 101 and 201 and electric energy is impressed upon the inks in accordance with image signals by means of recording heads 103 and 203 so that an ink image whose transferring characteristics are changed to adhesive properties is formed. When the ink image is transferred to a film 7, a prescribed image is recorded and displayed, but for making the transfer, magnetism is given to the ink 102 on the upstream side and a magnet 10 is provided on the back of the film 7 at the transferring location on the downstream side. As a result, the image part of the magnetic fluidic ink is attracted by the magnet. Since the disturbance of image is prevented and mixing of inks on the downstream side is sharply reduced in such way, a clear image display can be made on the film.

Title: Rolling/sliding component
Inventor: NOGUCHI SHOJI
IPC: F16C33/58
Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To reduce surface damage by relieving stresses on the actually contacting surface. SOLUTION: The size of stress is affected by the three-dimensional shape and roughness of a surface in microscopic terms, and the max. contacting stress enlarges with a smaller radius of curvature of the crest of each projection according to the surface roughness and lessens with a greater radius of curvature, and therefore, the radius of curvature of the crest of projection is made over 90 μm which is the saturated value of stress decrease. Using a projection distribution parameter which is smaller when projections are located in eccenticity toward one side and is greater when they are uniformly distributed more with regularity, the projection distribution parameter is set over 0.5 for making uniform the stress distribution. Because the radius of curvature of the crests of projections on the practical surface of an ordinary bearing steel is below 200 μm and the projection distribution parameter is below 0.8, their upper limit values are decided.

Title: Pointer moving method and pointing device
Inventor: IKEDA CHIHIRO
IPC: G06F3/0338
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To improve the operability by increasing the moving speed of the pointer with the time when a move command is generated and, when the command is canceled, changing the initial speed of the pointer according to the length of a cancellation time up to the generation of a next move command from the command cancellation. SOLUTION: When a move command for the pointer is inputted to a remote control receiver 3, a microcomputer 5 starts a program task by interruption. An operated key is decided first and moving direction is decided. Then the time Ts from when the move command for the pointer is reset at the time of a last process to the current time when the current move command is inputted is found. The time when the pointer is stopped from moving by resetting the move command at the time of the last process is stored in a memory. Then the length of the stop time Ts is judged by a comparison with a previously set time and the initial speed of movement is determined according to the length.

Title: Target for x-ray
Inventor: MORIMOTO SHINGO
IPC: H01J35/10
Filed: 1985-01-25
Abstract: PURPOSE:To provide a target durable against a very high rotational frequency, by reinforcing a graphite base with annular carbon fibers disposed around the graphite base or with a composite material consisting of annular carbon fibers and carbon. CONSTITUTION:Annular carbon fibers 3 or a composite material 5 consisting of annular carbon fibers and carbon is disposed around the graphite base 1 of a target for X-rays to reinforce the target. Since the annular carbon fibers 3 and the composite material 5 weigh light and have a high emissivity, the weight of the target is much reduced and it is cooled well. If the carbon fibers 3 or the composite material 5, the strength of which is very high, is wound on the graphite base 1 as tension is applied to the carbon fibers or the composite material, the effect of the reinforcement of the graphite base is made higher. Since the target is light, the load on a bearing for the target is so low that the decrease in the life of the bearing is small.

Filed: 1995-01-27
Abstract: PURPOSE: To prevent resolution from decreasing by separating a digital composite video signal into a signal group which containing many luminance components and a signal group containing many color difference components, and rearranging and putting the obtained signal groups together and encoding them. CONSTITUTION: An orthogonal transformer 11 performs the orthogonal transformation of the inputted composite video signal to generate signals A and B containing many luminance components, a signal F containing many color difference (B-Y) components, and a signal G containing many color difference (R-Y) components. A rearrangement unit 12 rearranges the signals A, B, F, and G obtained by the transformer 11 by using a specific expression to generate dummy 4:2:2 digital component video signals Y, U, and V. A digital component video signal encoder 13 encodes the dummy 4:2:2 digital component video signals Y, U, and V obtained by the rearrangement unit 12 as 4:2:2 digital component video signals. Therefore, the signal is transformed without increasing the number of samples.
