Abstract: PROBLEM TO BE SOLVED: To detect the position of a piston certainly corresponding to pressure fluctuation, by forming the guide pipe of a non-magnetic material by which a magnetic sensing material is guided, in such a manner that its one end is fixed to and sealed in a piston and its other end is formed into a free end, and fixing a magnetic sensing material operating permanent magnet on the guide pipe. SOLUTION: The guide pipe 20 of a non-magnetic material is arranged in the center of the bottom 2a of a piston 2, and a permanent magnet 30 is arranged at the free end 20a of the guide pipe 20. When pressure liquid is led to flow into a liquid chamber 10 from a liquid supply/delivery opening 8, the piston 2 is displaced while compressing filler gas in a liquid chamber 12. When liquid pressure is lowered, the piston 2 is displaced in a reverse direction. The permanent magnet 30 is also displaced by the displacement of the piston 2, and a current pulse is applied from an electrostrictive linear displacement detector 50 to a magnetic sensing material 40 at a constant interval. Hereby, a distortion generating signal is detected in the detector 50, and the position of the permanent magnet 30 from the detector 50 is measured.  Therefore, the position of the permanent magnet 30 can be continuously detected per impression of the current pulse, and the position of the piston 2 can be always monitored.

Title: Controller of air-fuel ratio
Inventor: HARA KAZUO
IPC: F23N1/02
Filed: 1983-08-11
Abstract: PURPOSE:To prevent running properties and purification of exhaust gas from deteriorating by accelerating convergence of an air-fuel ratio toward a logical air- fuel ratio, by increasing a correction quantity of the air-fuel ratio by varying a feedback constant when the air-fuel ratio has deviated greatly through a transitional phenomenon. CONSTITUTION:When a deviation of an air-fuel ratio becomes large, a pulse width of a pulse signal from a decision circuit 21 becomes wider, which results in lengthening of a cycle of a trigger pulse through a monostable multicircuit 34. Thus charging voltage of a condenser of a hold circuit 35 becomes high, an output of which is turned into an ''H'' level at the time when the voltage becomes higher than reference voltage Vo of a comparison circuit 36, through which a switch S2 of a constant changeover circuit 28 is turned on and each constant is varied greatly in a PI control circuit 22 through values of resistors R3 and R4. A proportional integral wave form, therefore, becomes like a region t2, and convergence of an air-fuel ratio to a logical air-fuel ratio is done rapidly by increasing a correction quantity of the air-fuel ratio.
