Title: Accumulator fuel injection valve
Inventor: KATOU MASAAKI
IPC: F02M45/12
Filed: 1984-06-27
Abstract: PURPOSE:To make injection pressure higher at the end of injection than at the beginning of injection, and maintain an injection start timing constant, by biasing a check valve and a needle valve with different springs. CONSTITUTION:When a needle valve 26 is lifted, fuel in a damper chamber 36 is pressurized by a rod 31. As flow of the fuel in the damper chamber 36 is limited by a restriction 38, injection is gently started. Pressure in accumulator chambers 16 and 17 has been alreadly increased by fuel in the accumulator chambers 16 and 17 and fuel from an injection pump 2, and an injection rate is gradually increased. At the end of supply of the fuel from the injection pump 2, pressure in a check valve chamber 19 is reduced, and a check valve 20 closes a fuel passage 25. As an internal volume of the damper chamber 36 is increased to be reduced in pressure, the needle valve 26 is further lifted to maximize the injection rate.

Title: Photomask blank
Inventor: MURAKI AKIRA
IPC: G03F1/00
Filed: 1984-06-27
Abstract: PURPOSE:To obviate the electrostatic breakdown of a mask pattern by forming a metallic silicide layer and light shieldable metallic film on a amorphous silicon film. CONSTITUTION:This photomask blank consists of the light transmittable substrate, the amorphous silicone film formed on the substrate, the conductive layer consisting of the metallic silicide formed on the amorphous silicon film and the light shieldable metallic film formed on the metallic silicide layer. The light shieldable metallic film consists preferably of Cr, W, Ni or Mo and the metallic silicide layer consists preferably of the silicide of said metals. Since the metallic silicide layer has the conductivity of 10<-4>OMEGA.cm order equiv. to the conductivity of an ITO film, the static electricity generated in the state of contact exposing with a water escapes through the conductive metallic silicide film and therefore the electrostatic breakdown of the mask pattern is obviated.
