Title: Method of fuel injection in diesel engine and its equipment
Inventor: KAWASAKI TADASHI
IPC: F02M47/00
Filed: 1983-04-08
Abstract: PURPOSE:To simplify the structure of a fuel injection valve and also to lower the working oil pressure by controlling a needle valve, which starts or stops fuel injecting operation of the fuel injection valve, in such manner that its movement is linked with that of a piston, which is supplied to its both upper and lower surfaces in a selective manner. CONSTITUTION:Fuel oil ''a'' whose injecting pressure is maintained at designated pressure during its operation is constantly supplied to a nozzle chamber 34 of a fuel injection valve 13. And when a needle valve 35 is pushed up as a piston 36 goes up, the fuel oil ''a'' passes a seat part 37 now being opened and is injected from a plurality of injection holes. The piston 36 is elevated by introducing working oil b onto the bottom surface of the piston 36. When fuel injection is to be stopped, a direction control valve 14 is switched so that the working oil b is applied to the top surface of the piston 36 in order to lower the piston 36, thereby closing the seat part 37 by means of the needle valve 35. With this contrivance, the piston 36 can be operated by a little power, allowing to reduce the piston diameter and to lower the working oil pressure.

Here, the cross-section of each extension 14 and branch section 8a is formed flat having longer axial dimensions 8aw, 14w than the radial dimensions 8ar, 14r. Consequently, the difference between respective path length at the inner and outer circumference of the intake path is reduced thus to achieve the purpose.

Filed: 1984-04-02
Abstract: PURPOSE:To eliminate the damage of a package in heating and to improve reliability, by applying machining, which deteriorates the adhesion with molding resin, to a part of the surface of an island support, and excluding swelled water content yielded in heating. CONSTITUTION:Wire bonding is performed by Au wire 4. Then sealing is performed by a molding resin 5. At this time, a product obtained by growing a transfer mold at 160-180 deg.C is removed from a molding jig. Immediately after the removal, the product is quickly cooled by cold water. By utilizing the difference in expansion coefficients {molding resin 5X10<-5>/ deg.C, 4-2 alloy (lead frame) 7X10<-6>/ deg.C}, adhesion between an island support 1 and the molding resin 5 is deteriorated (Part D). At the time of die bonding of the product, the island support 1 (alloy of 4-2 alloy iron and nickel) of the lead frame is heated for several seconds at a temperature of 400 deg.C or more in an atmosphere, in which the surface is liable to be oxidized. The product, which has an oxide film E whose thickness is 1,000Angstrom  or more on the surface, is sealed by the molding resin 5.
