Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To obtain an optimum fuel injection amount by correcting the variation of the injection property accurately regardless of the variation of the injection property of the cylinders, as to the fuel injection device of a multicylinder internal combustion engine. SOLUTION: A map as to the fuel injection amount Q and the fuel injection time τ of an injector is provided to each cylinder. The map memorizes the plural values of the common rail pressure. The fuel injection amount Q is calculated from the load and the rotational frequency of an internal combustion engine, and the injection time τ0 corresponding to the operated value Q0 of the fuel injection is calculated by a Q-τ map. By the pressure lowering of the common rail by the injection from the injector, the fuel injection amount is measured actually, and the correcting term of the map is calculated from the actually measured value. The Q-τ map of each cylinder is corrected by this correcting clause. The Q-τ map corrected at each cylinder is stored in a nonvolatile memory such as a flash memory.

Filed: 1985-07-18
Abstract: PURPOSE:To provide a heat exchanger by which a large heat transfer is obtained by providing a flat pipe and a large number of curved fins erected on the front surface of the flat pipe so that the convex surface side becomes the front surface side with respect to the airstream direction. CONSTITUTION:A flat pipe 3 is provided with pipelines so that an intertube stream flows in a direction perpendicularly intersecting an air current B, and headers 4 are mounted on both ends of the flat pipe 3. A large number of curved fins 5 are erected on one surface of the flat pipe 3 so that the convex surface side is located at the front surface side with respect to the air current direction, in a zigzag shape with a downward inclination (a). The flat pipe 3 and curved fins 5 are fixed by means such as brazing or the like. In carrying out a heat exchange between the air current flowing from the downward to the upward and the intertube air flow, the air current B is largely disturbed by the fin group formed by the curved fins 5 of a zigzag arrangement. Further, the convex side of the curved fin 5 is located at the front surface side with respect to the air current direction, and hence a thick bordery layer is hardly formed, and a large heat transfer is obtained between the curved fins 5 and the air current B.

Title: Pressure releasing device
Inventor: MORI KENJI
IPC: F16K17/40
Filed: 1979-12-10
Abstract: PURPOSE: To operate the device surely against invasion of an abnormal pressure and prevent the device from being broken simply by a reverse pressure by a method wherein the first safety repture disc at the input side of the pressure releasing device equipped to a steam generator is made into a tension type and the second safety rupture disc at the output side is made into a converting type.  
     CONSTITUTION: When a water leak accident, in which several pieces of heat transmitting tube are broken in the steam generator, occurs, water is reacted with sodium, the pressure in the steam generator is increased rapidly and two sleets of the safety rupture discs 19a, 19b for the pressure releasing device are ruptured sucessively. In this process, the reverse pressure is applied from a discharging piping 5, but the second safety rupture disc 19b is functioned as the tension type rupture disc against the reverse pressure, therefore, it is not ruptured even if the reverse pressure which is several times of a positive rupturing set pressure is applied. Because the first safety rupture disc is the tension type, the rupturing property thereof is very sure.
