Title: Fuel injection device of engine
Inventor: TOKUMARU TAKESHI
IPC: F02M63/00
Filed: 1996-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection device of an engine preventing leakage of fuel from an opening/closing part by utilizing fuel pressure within a balance chamber for injection-valve closing force of an opening/closing valve. SOLUTION: When an opening/closing valve 5 is opened, the valve stem 34 of the opening/closing valve 5 which is inserted and passed in/through an emission path 33 formed in a control member 13 moves in the direction of a balance chamber 30. Because a valve head 38 opens the opening tip part on the side of the balance chamber 30 of the emission path 33 and lowers fuel pressure within the balance chamber 30, a needle valve 17 is lifted and fuel is infected. When the opening/ closing valve 5 is closed with a return spring 35, leakage of feel passing the opening/closing valve 5 is prevented because fuel pressure within the balance chamber 30 acts on the valve head 38 and acts in the direction of closing the opening/closing valve 5.

Abstract: PROBLEM TO BE SOLVED: To reduce chip in manufacturing and to improve plowing characteristics in lighting by constituting an electrode of a cylindrical base part called a shaft part and a tip part formed into a cone and by molding the tip part in the radial direction using a molding dice formed into a shape matching to a prescribed tip part. SOLUTION: A negative electrode 4 is composed of tungsten doped with 0.4 wt.% ThO2 . To secure the stability of the height of the arc, a cylindrical base part forming a shaft part 5 of a negative electrode 4 is gradually getting narrower into a truncated cone to be formed into a tip part 9 so that the outer casing part 11 of the cone has an aperture angle α and the discharge side is finished at the flat part 10. The tip 9 is formed by forging in the radial direction, the organization structure is extremely pulverized by the shaft part formed of a drawing organization structure. Only the flat part 10 is aftertreated by polishing in the last. The stability of the organization structure in the region of the tip part 9 subjected to high thermal load can be thus improved.

Title: Energy saving type gas appliance
Inventor: OGASAWARA HIDEYUKI
IPC: F23D14/06
Filed: 1984-11-26
Abstract: PURPOSE:To improve a heating efficiency of a domestic-use gas equipment by a method wherein both blocks or plates are recessed and overlapped to each other to form a sub-combustion chamber and this sub-combustion chamber is arranged at a flame outlet port. CONSTITUTION:A small sub-combustion chamber 6 which is almost closed to form a space at a flame outlet port of the burner in which a burner body 1 and a burner head 2 having several teeth at its lower surface are overlapped to form the flame outlet port of the burner. This sub-combustion chamber is formed by aligning the concave grooves of the burner body with the concave groove of the burner head. The flame in the combustion reaction is forcibly recirculated in the sub-combustion chamber 6, the recirculated part always acts as a source of ignition to cause the main flame to be continuously ignited and made stable and at the same time an injection speed near the flame hole wall is decreased by this recirculated eddy current, a fuel gas injection speed is approached to the distribution of combustion speed to make a balance between them and to prevent a lifting of the flame. The root of the flame is protected by the sub-combustion chamber 6 and so a blowing interruption of the flame caused by the secondary air can also be prevented.

Title: Control system of terminal device
Inventor: UCHIDA YOSHIAKI
IPC: G06F11/00
Filed: 1983-12-27
Abstract: PURPOSE:To eliminate a mistake when the using state of a terminal device is checked by reading out the value of a counter for every prescribed period to compare this value with a prescribed reference level and deciding the terminal device is not used when the value of the counter is larger than the reference level. CONSTITUTION:A host computer 1 outputs an inquiry to a terminal 2 through a circuit, and a timer 5 is reset if it is decided by a detecting circuit 4 that a maximum value detecting circuit 11 of the terminal 2 does not reach the maximum value. Then the timer 5 starts counting again. An interruption is applied to the terminal 2 after the counted value of the timer 5 reaches a prescribed level. A counter 8 of the terminal 2 is set at zero for each key input and therefore shows the small value when the terminal 2 is in use. When the circuit 11 reaches the maximum value, the circuit 4 shows the coincidence. This coincidence is informed to a monitor circuit 6 to indicate a power supply breaking circuit 7 from the circuit 6 to turn off the power supply of the terminal 2.
