IPC: F02D9/02
Filed: 1999-11-17
Abstract: PROBLEM TO BE SOLVED: To provide a rotating direction switching and controlling method for reversing the rotating direction of a two-cycle internal combustion engine for driving a traveling device. SOLUTION: When a reversal command is generated at a time t0, inflow of air into an intake passage of an internal combustion engine is interrupted and engine speed N of the internal combustion engine is lowered. When engine speed of the internal combustion engine reaches a set engine speed N1 set to be lower than idling speed N0, inflow of air into an intake passage is restarted and an ignition position of the engine is advanced up to an over advance angle position. When a new air-fuel ratio within the cylinder becomes a value suitable for combustion at a time t2, combustion by ignition at the over advance angle position and the rotating direction of the engine is reversed. Subsequently, the internal combustion engine is ignited at a position suitable for maintaining rotation of the internal combustion engine in a state that the rotating direction is reversed and an operation of the internal combustion engine is performed in a state that the rotating direction is reversed.

The tray 15 at the start position S is moved to a heating position H at the point of the time a pressure gage 12 registers 3×10<-6> Torr. The substrate is then heated to 150 deg.C by a lamp heater 13. The vacuum degree of the pressure gage 13 falls gradually according to heating and, thereafter, the vacuum degree rises again. The tray 15 in the heating position H is moved at time the pressure gage 12 again registers 3×10<-6> Torr. The substrate is then subjected to sputtering in order of titanium and palladium and is stored in a product tray stock position P.

Filed: 1988-12-27
Abstract: PURPOSE: To disable the recycle of a syringe by providing a plunge rod with an elastic block means to be pressed onto the inner wall of a syringe barrel and engaging this means with an edge so as to block the syringe barrel from moving back in reloading direction. CONSTITUTION: The syringe is loaded by moving the position of the plunger rod to a position, where a rim 15 of a member 12 touches the edge of a loop- shaped member 22, or a little lower than this position. In this case, air remaining together with liquid is exhausted by pushing down a piston rod to a position where a safety member 20 touches a clamping means 18. When performing injection, for a vein test, an operating rod 7 is pushed down to the final position after a little liquid is extracted from a patient, the full quantity of liquid in the syringe is injected and the safety member 20 is removed from the operating rod 7.  After the 1st injection, the operating rod 7 is moved back and when the reload of the syringe occurs, a connecting member 8 lets the operating rod 7 follow up a piston 4 to a position, where the rim section of the block member 12 is engaged with the edge of a recessed part 19, so that the connecting member 8 can be prevented from moving up any more.
