Title: Hydraulic pressure controller in lubrication circuit of internal combustion engine
Inventor: FUKUNAGA HIROYUKI
IPC: F01L1/34
Filed: 1996-08-14
Abstract: PROBLEM TO BE SOLVED: To secure a high control response and stability of a hydraulic pressure driving device by preventing a shortage of hydraulic pressure of a lubrication oil which is supplied to some hydraulic pressure driving device attached to a lubrication circuit in a state in which a lubrication oil temperature of an internal combustion engine is high and a revolution number is low. SOLUTION: A check valve 25 is provided on a hydraulic pressure driving oil channel 12 for supplying pressurized lubrication oil to at least one hydraulic pressure driving device (for example, valve timing variable mechanism), the channel being branched off from a lubrication oil channel 18 on the side of a main stream. At the same time, a pressure accumulator 26 is provided at a downstream side of the check valve 25 and at an upstream side position of a valve timing variable mechanism 1.  In a period when an engine is rotated at a high speed, and a pressure of lubrication oil exhausted by an oil pump is set to a high pressure, the hydraulic pressure is accumulated in the pressure accumulation chamber so that when the lubrication oil pressure is lowered next time, the oil channel is automatically interrupted with the check valve, and at the same time, a high pressure lubrication oil is supplied to the valve timing variable mechanism 1 via a hydraulic pressure control valve from the pressure accumulation chamber 32.

Title: Operation management system for unmanned vehicle
Inventor: OOSHIMA MUNEKUNI
IPC: G01C21/00
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To provide the system which can always ensure the normal operation management of an unmanned vehicle by estimating the areas on the traveling course of the vehicle where a GPS receiver is unable to measure the accurate present position of the vehicle and instructing the vehicle to travel on another course to bypass those estimated areas. SOLUTION: An arithmetic part 3 estimates the areas where a GPS receiver 1 is set in a measurement unable state on a map stored in a map information storage part 2 at every prescribed time based on the satellite data received from the receiver 1 and the data on the buildings around the traveling course of an unmanned vehicle 4 which are stored in the part 2. Then the part 3 selects a traveling course that can reach a prescribed target position in the shortest distance and without passing the estimated measurement unable areas. Thus the vehicle 4 to undergo its operation management calculates a slippage amount between its present position and its traveling course based on those present position and traveling course that are measured by the receiver 1. Then the steering angle of the vehicle 4 is controlled, so that the slippage amount is eliminated.  As a result, the vehicle 4 can travel to its target position.

Title: Electrode chip for spot welding
Inventor: NAKANO SHOZABURO
IPC: B23K11/30
Filed: 1987-08-31
Abstract: PURPOSE:To perform satisfactory welding and to extend the service life of an electrode chip by forming double structure consisting of the outside peripheral part forming an electric conductive member as an electrification part and the central part forming an electric nonconductive part as a pressurization part in the electrode chip for spot welding. CONSTITUTION:The central part 3 of the electrode chip of the pressurization part is made of electric nonconductive material of ceramic and the electrification part of its outside peripheral part 2 is embraced by electric high conductive material such as a Cu-Cr alloy to form the double structure. The tip of the electrode chip 3 at the early stage of welding is flat but when the number of welding spots increases, the outside peripheral part 2 disappears and a shape changes to (a) (b), so the electrification area is narrowed. When the electrification is executed in this state, a current flows from the electrification part of the outside peripheral part 2 to steel plates 4 and flows to the outside peripheral part 2 directly under the ceramic 3. By this method, the satisfactory welding can be performed and the service life of the electrode chip can be extended.

Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To reduce the degree of a stress relaxation of a lead holding member even in the case of using for a long time and to absorb irregularity of a lead diameter by forming a reservoir at an inside of the member and integrally forming a larger reservoir than the reservoir at the rear of the member.

Inner walls 6a, 7a of the reservoirs 6, 7 are thinner than outer walls 6b, 7b. When a lead having a large diameter is used, the wall 6a of the reservoir 6 is pressed in an outside direction, the reservoir 6 is contracted, fluid in the reservoir 6 is moved to the reservoir 7 by a contracted volume. As a result, the reservoir 7 is bulged, and the wall 7a is swelled.

Title: Molding die for powder wall-forming
Inventor: EGUCHI TORU
IPC: B29C39/26
Filed: 1986-09-14
Abstract: PURPOSE:To enable a product of complicated form with reverse taper to be molded in a single molding process by a single seamless molding die by mixing a shape retaining agent varying reversibly form softening to hardening or from low viscosity to high viscosity into molding die materials, and forming a molding die cavity in the area of hardening or high viscosity temperature area of the shape retaining agent. CONSTITUTION:A shape retaining agent varying reversibly from softening to hardening and from low viscosity to high viscosity is used. The typical ones are rubber, Metolose and hydroxyethyl cellulose. The shape retaining agent is mixed with powder of ceramics, metal, resin or the like in which a master model is filled. Filling is carried out in the area of low viscosity or softening temperature area of the shape retaining agent, and when the temperature is varied for high hardness or high viscosity, a die is extraordinarily strengthened following hardening or turning into high viscosity of the shape retaining agent. At said stage, the master model is removed by transforming, melting or vaporizing to form a cavity. When, for instance, slurry, for casting of a ceramic wave, containing approximately 30 % water content is poured into the die, water in the slurry is absorbed by the die, and wall-forming is effected. As being cooled, the shape retaining agent is reformed into the original agueous solution, and the die is recovered to the state of flowability, the molded production inside may be removed out of the die without any damages.

Title: Composite foil for cathode of electrolytic capacitor
Inventor: FUKUOKA KIYOSHI
IPC: H01G9/04
Filed: 1988-09-01
Abstract: PURPOSE:To strongly etch an aluminum foil and to increase the electrostatic capacity of the foil by employing a synthetic resin film as the core of a composite foil for the cathode of an electrolytic capacitor to increase the mechanical strength of the foil. CONSTITUTION:An aluminum composite foil for the cathode of an electrolytic capacitor is composed of two foils 1 of a aluminum of 99.4-99.88% of purity or aluminum alloy based on the aluminum of the purity of this range, and a synthetic resin film adhering therebetween. The aluminum foil of the cathode does not normally need compounding after etching, and even if it is compounded, it shows a very low voltage. Accordingly, there exit fine pits, and the larger an etching pattern having a large surface area is, the higher the electrostatic capacity increases. Simultaneously, since it is not necessary to pay attention for the detect of the compounded film, it is not necessary to use aluminum of high purity like an anode.
