Abstract: PURPOSE:To prevent the distal end of a controlling valve from projecting in an exhaust path when the controlling valve is fully opened in two plate-like controlling valves moved back and forth to very exhaust timing by providing the controlling valve such that its widthwise center line is at a predetermined angle to a plane perpendicular to the sliding direction of a piston. CONSTITUTION:A cylinder body 1 is provided on the upper position of an exhaust path 3 slidably two plate-like controlling valves 7 which have their longitudinal axis l1 inclined by a predetermined angle theta1 to the sliding direction of a piston and the widthwise axis l2 inclined by a predetermined angle theta2 to a plane perpendicular to the sliding direction of the piston. The respective controlling valves 7 are formed on one end adjacent no the cylinder 2 side with an arcuate surfaces 7a having the same curvature as that of the cylinder 2. Thus, when the controlling valve 7 in a high rotation region retreats from the exhaust path 3 to be fully opened, the outside distal end of the valve project in the exhaust path 3 so that exhaust flows smoothly in the exhaust path 5.

Filed: 1990-08-31
Abstract: PURPOSE:To suppress false lock by providing a frequency conversion section and a signal recovery section separately, enabling the frequency conversion section to attain frequency synchronization and allowing the signal recovery section to make phase detection. CONSTITUTION:A frequency conversion section A makes control to obtain a prescribed 2nd IF signal 22. On the other hand, the signal 22 in a signal recovery section B is branched by a branching device 8 via a band pass filter 7 to phase detectors 9,10 respectively. Then an output of a reference oscillator 6 is phase-shifted by a variable phase shifter circuit 11, a signal branched by a distributer 12 is fed to a phase detector 19 through a pi/2 phase shifter 13 and fed directly to a phase detector 10 respectively, the signals are phase- detected respectively and a base band signal is outputted. A control circuit 14 generates a control signal 23 based on the base band signal to control a phase shift quantity of the variable phase shift circuit 11. Thus, optimum phase synchronization detection is always realized in the detectors 9,10. Since the signal recovery section B implements phase detection not by frequency synchronization but by phase synchronization only, no false lock is caused.
