Title: Fuel injection type engine
Inventor: ODA HIROYUKI
IPC: F02M69/04
Filed: 1984-04-26
Abstract: PURPOSE:To prevent undesired fuel from scattering at a branch section and prevent the fuel from sticking to the inner wall surface partitioning two branch passages by injecting the fuel to the branch section of the two branch passages through a fuel injection valve. CONSTITUTION:The start point G of a fuel dispersion section V is specified at the upstream side of a branch section 10c where branch passages 25a, 25b are branched, and the dispersion angle theta of the dispersion section V is specified so that the dispersion section V is not spread outside the scope formed by valve stems 15a, 16a of both intake valves 15, 16. Accordingly, out of the injected fuel, an extremely small quantity is brought into contact with the inner wall surface partitioning the branch passages 25a, 25b. Since the fuel hits the branch section 10c at the dispersion section V, the degree of dispersion at the branch section 10c is made smaller than that when the hitting portion is a straight section U.

The terminal voltage of the diode D3 connected in series with the armature M and field winding F of the motor is applied as the speed signal to the speed control circuit 4, wherein the charged quantity of a capacitor C4 is controlled depending on the difference between the speed signal and a set signal applied by a speed setting variable resistor VR. The turn-on phase angle of the thyristors Q1, Q2 is thus regulated to control the supplied voltage to the motor.

     CONSTITUTION: The object to be plated composed of metals of baser ionization tendency than silver are put as cathode in the plating bath of 1×10 6  to 1×10 15  at 25°C in the complex compound forming constant with silver other than thiocyanic acid, 10 -2 mol/l or over in concentration of the complex forming agent of silver (except thiocyanic acid) and 10 -5  to 10 -2 mol/l in concentration of silver ions. DC voltage of maximum 2V is applied between this cathode and anode and electroplating is accomplished at cathode current densities 10 -1  to 10 2 mA/dm 2 . In this way, the substituting plating film is slowly formed at low current densities by lowering the silver concentration in the bath and allowing such complex forming agents (NH 3 , S 2 O 3   -- , etc.) in which silver stably exists to exist in large volume. Thick deposition plating of silver on this plating film may be readily performed.

Abstract: PURPOSE: To boost brake pressure largely even when a pressure source goes in failure and stop a vehicle certainly in emergency with a minor pedaling force. CONSTITUTION: When the liquid pressure of an accumulator 5 sinks below a specified level, a pressure switch 13 is turned on. If in this condition, a brake pedal 2 is stamped, a pedal switch 14 is turned on. Accordingly an ECU 15 emits a control signal, and a selector valve 12 is changed over to the position II. Thereby a negative pressure from a vacuum tank 10 is applied to the pressure receiving surface of power piston 16 on its liquid pressure piston 17 side, so that the power piston 16 advances. Thereby the liquid pressure piston 17 is actuated to generate a brake liquid pressure, and brakes are applied. This brake pressure has a very larger value approx. equal to the brake pressure generated with the operation of a liquid pressure servo unit 3 while the pressure source is in normal function.

Abstract: PURPOSE:To obtain molds for high-molecular material capable of getting rid of the burrs, by permitting the sections connected with parts constituting cavities for molding, and the broad surfaces around the cavities to move relatively to the abutting surfaces of the upper and lower molds. CONSTITUTION:By pressing down a cylindrical body 6 by a plate 13, a high- molecular material for example unvulcanized rubber is filled in the cavities 4, 5, and the rubber is heated under pressure to be vulcanized.

Then due to these burrs the upper mold 1 and the rod-like body 8 are raised to some extent whereas the surface 7 is concentratedly forced onto the surface 10 to make them in firm contact so that the distance between them become almost nill. Thus, the burrs and the product parts in the cavities 4, 5 are completely separated off.
