Title: Multiple layer gasket
Inventor: MOROHOSHI TSUNEJI
IPC: F16J15/08
Filed: 1990-04-05
Abstract: PURPOSE:To dispense with any beading work as well as to keep the whole joining surface in uniform initial bearing pressure at all times by joining respective projecting surfaces themselves of two elastic materials, subjected to embossing finish uniformly over a stainless steel sheet, together so as not to overlap these embossed patterns, and setting up a plate, equipped with a soft layer at least in one side, at least one side of the elastic material. CONSTITUTION:Each of soft layers 4-1, 4-2 in a multilayer gasket hits on a contact surface between a cylinder head and an engine block, so that uniform contact can be done without deforming the cylinder head and the engine block by claming force of a bolt or suchlike. At this time, two elastic materials 2-1, 2-2 provided with embossed patterns 5, 6 are elastically deformed by clamping force of the bolt or the like. After hours, however, the soft layer incurs a creep. but a portion for the creep is countervailed by elastic restoring force quantity of these two elastic materials, thus uniform initial bearing pressure can be kept on the contact surface between the cylinder head and the engine block at all times.

Title: Safety device of robot
Inventor: KANBARA HIROBUMI
IPC: G05B19/19
Filed: 1984-05-07
Abstract: PURPOSE:To prevent the interference without using a memory circuit nor a special control circuit by setting a non-interference area, a semi-interference area and an interference area according to the revolving angles of two robots. CONSTITUTION:Proximity switches 11-14 are turned off when they are set opposite to notches 9 and 10 and then turned on when they are set opposite to plates 7 and 8 respectively. For instance, switches 11, 12 and 14 are kept off with a switch 13 kept on respectively. Under such conditions, an AND gate produces a signal of an H level and therefore a signal of an H level is produced at an output terminal 20 of a discriminating circuit 15. This signal is used for emergent stop of both robots. In case switches 11 and 12 are kept off with switches 13 and 14 kept off or on, an operation enable state is set since both robots have no interference to each other. As a result, an output signal of an L level is produced at the terminal 15.

Title: Coating method
Inventor: MATSUMURA TERUO
IPC: B05D1/30
Filed: 1979-07-14
Abstract: PURPOSE: To form an even coating film on a substrate to be coated by coating paint on the substrate by a flow coater then blowing air to the coated surface.  
     CONSTITUTION: Paint 3 is coated by a flow coater 1 on the top surface of a substrate 2 to be coated moving on a stage 5. Before the paint 3 dries up, air 13 is  blown to the coated surface 4 from the air gun 12 under the low pressure of the extent of not causing the paint 3 to blow off. This allows the surrounding paint 3 to forcefully flown into the longitudinal streaks of the coated surface 4 and in the pinhole portions thereof, thereby eliminating the longitudinal streaks and the pinholes. Thence, the paint 3 of the coated surface 4 is dried and set, whereby the  uniform coating film is formed on the surface of the substrate 2 to be coated. If at  this time the air pressure is regulated, the desired coating films from the coating  film of a smooth surface to the coating film of satin patterns may be obtained.

Title: Polishing means
Inventor: GOCHO TETSUO
IPC: B24B37/013
Filed: 1991-03-28
Abstract: PURPOSE:To enable the effective judgment of polishing end point by monitoring the noise generated during polishing and detecting a variation in the noise when a portion to be polished is removed. CONSTITUTION:A workpiece, placed on a table 74, is polished by a polishing plate P, and a noise E is monitored during the polishing operation using a noise pickup means 3. SiO2, buried material 5, is polished in the beginning. When SiO2 polishing is completed, a Si3N4 layer, the polishing stopper layer 2, is exposed. At that time the waveform of SiO2 polishing noise is replaced by that of Si3N4 polishing noise since a noise during polishing operation varies depending on materials being polished. When the variation in waveform is detected, it is judged that the end point of SiO2 polishing has been reached. Thus the end point of polishing is effectively judged.

IPC: F02D29/02
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To accurately decide the pass propriety of a vehicle by correcting a passable speed in accordance with the curve shape of a road. SOLUTION: A 3rd deciding part M42 identifies a simple curve from a sigmoid curve by deciding whether a curve is a single curve or a sigmoid curve, and a 4th deciding means M43 identifies a sigmoid curve from a curve that is connected to both ends of a straight road by deciding whether the curve is a sigmoid curve or not. A passable speed at which a vehicle can pass through nodes on a curve is calculated based on a pass state decision amount θN/LN which is one that divides the azimuth change amount of a vehicle θN by the travel distance of the vehicle NN. A 1st correcting means M44 corrects the amount θN/LN and lowers a passable speed when plural nodes exist on the same curve, and a 2nd correcting means M45 corrects the amount θN/LN and lowers the passable speed when a node exists on a sigmoid curve.

Title: Surface light source device
Inventor: TAKEMURA TORU
IPC: G09F13/18
Filed: 1988-04-13
Abstract: PURPOSE:To prevent occurrence of luminance spots on the surface light source of a surface light source unit by providing an optical distributor between part adjacent to the linear light source and part adjacent to the translucent platy body of the surface light source unit. CONSTITUTION:This surface light source unit 1 is constituted of linear fluorescent lamps 2 which are arranged in one linear light source and a translucent platy body 4 composed of plural transparent thin plates 3 having different lengths piled up upon another. Since one-side edges 4a of the thin plates 3 constituting the platy body 4 are trued up on the fluorescent lamp 2 side, the other-side edges 4b form steps and radiated luminous fluxes are made incident to the trued-up edges 4a and emitted from the step-forming edges 4b. Moreover, the luminous fluxes made incident to a pair of optical distributors 9 which are abutted against each other at the position matching to the position where the two bases 2a of the two fluorescent lamps are abutted against each other are emitted from the distributors 9 after refraction. Therefore, the luminous fluxes emitted from the distributors 9 compensate the sections of the bases 2a which do not emit light, since the luminous fluxes are observed as if they are emitted from the base 2a sections. Thus the cause of a luminous spot in the surface light source can be eliminated.
