Title: Direct injection type diesel engine
Inventor: FURUKUBO TATSUMI
IPC: F02M41/12
Filed: 1983-07-01
Abstract: PURPOSE:To permit to operate surely under severe condition with a simple structure by a method wherein a stroke control mechanism, controlling the stroke of a piston in a plunger chamber so as to elongate when a delivery pressure is low and shorten when the same pressure is high, is provided in a fuel injection device. CONSTITUTION:The amount of injecting fuel is controlled by the valve opening period of an injection nozzle determined by a pressure in the plunger chamber 14 while the amount of increasing of the injection period is controlled by the stroke control mechanism 26. The delivery pressure is introduced to the pressure receiving surface 56C of a damper piston 56 through paths 80, 78, 70, 68, first spring chamber 52, a notch groove 64A and the path 64, however, the delivery pressure becomes higher when the rotating speed is high. The pressure receiving surface 56C is larger than a small diametral section 56B, therefore, the piston 56 moves to the left against a spring 66 and the moving stroke of the piston 18 is decreased in the pressurizing stroke of the plunger chamber 14, which is effected by the plunger 12. According to this constitution, the fuel may be injected during suction air injecting period in which swirl is formed in a combustion chamber.

Filed: 1990-05-10
Abstract: PURPOSE:To unnecessitate engine cooling water and prevent freezing trouble by radiating/condensing refrigerant, compressed by an engine-driven refrigerant compressor, by an indoor heat exchanger, and leading the condensed refrigerant into an outdoor heat exchanger and also leading a part of it into an engine to cool the engine. CONSTITUTION:During heating operation, a refrigerant compressor 5 is driven by an engine 1 to compress refrigerant. The compressed refrigerant passes a four-way valve and is sent to an interior heat exchanger 10, where the compressed refrigerant is heat-released and supplied to indoor heating, and also condensed. The condensed refrigerant passes a pressure reducer 22 and is sent to an outdoor heat exchanger 8, where the condensed refrigerant is evaporated and returned to the compressor 5 from an accumulator 6. At the same time, a part of it is branched from the pressure reducer 22, passes a pressure reducer 23, and is led into the engine 1 and an engine exhaust gas heat exchanger 2 to cool them and recovered after evaporation. Engine cooling water therefore becomes unnecesary, and freezing can be prevented.

Title: Method for detecting small hole
Inventor: KONAKAWA YOSHIKO
IPC: H01L21/66
Filed: 1990-05-10
Abstract: PURPOSE:To certainly detect the generation place of a small hole by applying the oxidizing or reducing potential of a chemical substance discoloring by oxidation or reduction to an electrolyte solution containing said chemical substance using a semiconductor substrate as an electrode. CONSTITUTION:MV<2+>1 is colorless and becomes MV<+2> by the reduction of one electron of MV<2+>1 to show blue. Potential reducing one electron of methylviologen 1 is applied while the potential of a semiconductor substrate 8 to a reference electrode is kept constant by a potentiostat 3. Since an oxide film 9 is an insulating film, the electron flowing to the semiconductor substrate 8 comes into contact with an electrolyte 5 only at a small hole part 7. Methylviologen 1 is drawn near to the electron 6 on the surface of the semiconductor substrate whose small hole part 7 is exposed and becomes a reduced seed 2 by the reduction of one electron thereof. Since this reduced seed 2 is blue, only the small hole part 7 shows blue. Therefore, the point developing blue is counted to make it possible to detect a small hole.

Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To assist enhancement of the accuracy of discrimination by reducing fluctuation of the speed of a bill fed to the next process, particularly a discriminating part, and reduce the overall length of a device. SOLUTION: A feed roller 1 has a number of pointed, conical microprojections 2 on its outer peripheral surface.
