Title: Fuel injection device of internal combustion engine
Inventor: TSUZUKI NAOYUKI
IPC: F02M47/00
Filed: 1990-07-09
Abstract: PURPOSE:To uniform the fuel injection amount of each injection valve by controlling the rush current to an electromagnetic coil to substantially uniformalize the time from the current application to the electromagnetic coil of a fuel injection valve to the time a needle starts to displace in the direction of the valve opening, or the needle finishes the displacement. CONSTITUTION:In a fuel injection valve 3 provided at each cylinder, a solenoid valve 51, when it is turned ON, communicates an oil pressure chamber 50 with a fuel tank 11, and thereby the pressure in the oil pressure chamber 50 is reduced. An upward force acting to a needle 42 is then increased, and a command piston 47 and the needle 42 are squeezed upward. As a result, a nozzle port 41 is opened and the fuel is injected into a combustion chamber. In this case, since the delaying time from the starting of current application to a driving coil of the electromagnetic valve 51 to the starting of the conversion displacement of the electromagnetic valve 51, and the converting speed of the electromagnetic valve 51, are different in every solenoid valve 51, the delaying time and the converting speed of the valve 51 are measured beforehand, and a rush current to the driving coil is made larger as the delaying time is larger, or the converting speed is smaller.

Title: Wire drawing method for steel wires
Inventor: MURAKAMI MASAAKI
IPC: B21C3/10
Filed: 1986-07-30
Abstract: PURPOSE:To improve the surface state of the wire to be worked, to improve a fatigue resistance and to prevent the deterioration in stiffness due to the rise of a wire drawing temp. by performing continuously the wire drawing by the pressure die incorporating a pressure lubricant >= the final four steps and performing the wire drawing in the state of the whole dies dipping into the lubricant. CONSTITUTION:The lubrication method at the wire passing time in the initial wire drawing is to lead a lubrication oil into the main body of a wire drawing machine through a pump 12 and piping 14 from a tank 11 and to feed to wire drawing dies 3, 4. After completion of the wire passing work of the whole dies a drain valve 15 is closed, a changeover switch 16 is set to an overflow side and a dipping lubricant is filled up inside the wire drawing machine main body 1. A high pressure pump 18 is then operated, the lubricant pressurized in 10-100kg/cm<2> is led into a pressure die 4 from the piping 6 and the wire drawing machine is operated at the step when the pressure of the lubricant inside the pressure die 4 is attained to the prescribed pressure. The fatigue resistance is thus improved by the improvement of the surface state of the wire 8 to be worked and the stiffness deterioration of the wire to be worked due to the wire drawing heating can be prevented.

Title: Semiconuctor device
Inventor: OKADA TAKASHI
IPC: H01L29/73
Filed: 1981-11-09
Abstract: PURPOSE:To prevent generation of short-circuit between a gate electrode and source and drain electrodes, and to reduce floating capacity at an MISFET having the metal gate electrode doped with impurities by a method wherein the source and drain ohmic electrodes are constituted of a metal silicide dopes with impurites, and a part thereof is buried in a substrate. CONSTITUTION:An opening 13 for diffusion is provided selectively in the SiO2 film 11 covered on an Si substrate 12, and tungsten 14 containing arsenic is adhered thereon. When it is heat treated, it is converted into tungsten silicide 15, and the silicon diffuses to form a P-N junction part 16.

Title: Cooling apparatus
Inventor: MASE TOKUTARO
IPC: F25B13/00
Filed: 1988-07-19
Abstract: PURPOSE:To increase the pressure of the gas at a junction of a main refrigerant channel and a auxiliary one so as to increase the pressure on the suction side of the compressor by installing an auxiliary evaporator in the auxiliary refrigerant channel, which bypass the evaporator and the refrigerant flow control valve in the main refrigerant channel, in the path of the air current from the condenser. CONSTITUTION:The pressure on the suction side of the compressor 2 gradually decreases because of gradual narrowing of the opening of a refrigerant flow control valve 16 as the indoor temperature declines during the continuous cooling operation. When the pressure on the suction side decreases below a specified degree, a low pressure cutout 21 works and a solenoid valve 18 opens a passage. As a result, the flow of the refrigerant which has passed through a condenser 4 branches into a main refrigerant channel A and an auxiliary refrigerant channel B. Since an auxiliary evaporator 20 in the auxiliary refrigerant channel B is positioned in the path of the air current from the condenser 4 and exposed to the air heated by heat exchange by the condenser 4, the vaporization of the refrigerant takes place at a definitely large rate than it is out of the path of the heated air, resulting in an increase in the pressure of the refrigerant gas.

Title: Collision avoiding method for robot arm
Inventor: MAKINO HIROSHI
IPC: B25J19/06
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To operate tool points without collision of arms with each other by deciding the operation of tool points in such a manner as to avoid collision when it is determined that there is the possibility of collision. SOLUTION: This method comprises a teaching point collision determination step, a moving collision determination step and a collision avoiding step. First of all, in the teaching point collision determination step, a collision in the teaching points TCP0', TCP1' of tool points 10, 11 is determined. First the X- coordinate of TCP0 is subtracted from X-coordinate of TCP1' to obtain a distance in the X-coordinates of TCP0' and TCP1', and it is determined whether the distance is larger than a designated margin or not. Further when it is smaller than the designated margin, there remains a possibility of collision, so the Y-coordinates of the teaching points are compared with each other. When the Y-coordinates are equal, the condition where the arms intersect each other or the condition of the collision is determined.  Accordingly it transits to the collision avoiding step to conduct collision avoiding process.
