Abstract: An air-cooled multi-cylinder engine including two temperature sensors each attached to different cylinders. The temperature difference between the two cylinders is detected by the temperature sensors. The air-fuel ratio in each cylinder is made the stoichiometric air-fuel ratio by decreasing the amount of fuel fed into higher temperature cylinders and increasing the amount of fuel fed into lower temperature cylinders.

Abstract: An aircraft piston engine control system according to the present invention has a fuel supply passage for supplying fuel to the engine. A fuel regulation device is arranged in the fuel supply passage, is linked to a throttle lever, and regulates an amount of fuel so as to realize a first air-fuel ratio which is more rich than the stoichiometric air-fuel ratio. A fuel decreasing passage is connected to the fuel supply passage between the fuel regulation device and the engine. A fuel decreasing device is arranged in the fuel decreasing passage, and decreases an amount of fuel regulated by the fuel regulation device so as to realize an optimum air-fuel ratio according to the current engine operating condition.

Abstract: A safety control apparatus for a reciprocating engine equipped with two control systems to be able to sufficiently cope with a false normal state in which a normal state signal is output to an observation circuits of the control system despite the fact that an abnormal output has been fed to the actuators of the fuel injection system or the ignition system as a result of an abnormal operation in the control unit in the control systems. The pair of control systems are provided with a false normal state detection circuits for detecting the false normal state in addition to the provision of first and second control units for controlling the engine and an operation observation circuit therefor. When the false normal state detection circuit judges that the control system now in operation is abnormal, the engine control system is changed over to the standby system via the output change-over circuit to safely control the engine.

Abstract: An engine including a supercharger wherein a waste gate valve is provided in the bypass passage bypassing the exhaust turbine of the supercharger and the supercharged pressure is controlled by the waste gate valve so that when the opening of the throttle valve provided in the intake duct falls under a set level, the air-fuel mixture is made lean and when it becomes greater than the set opening, the air-fuel mixture is made rich. When the air-fuel mixture is changed from a lean to rich mixture, the opening of the waste gate valve is made larger to reduce the supercharged pressure and thereby prevent abrupt fluctuations in the engine output.

Abstract: A vehicle transmission control arrangement in which an automatic clutch is disengaged in response to a signal received from a shift lever switch provided to detect an operation of a shift lever for shifting a speed changing mechanism. A comparator is provided to determine whether a detected or determined output torque of an engine is smaller than a predetermined reference value below which an increase in the engine speed upon full disengagement of the clutch will not significantly deteriorate a driving comfort of the vehicle. A clutch control device is adapted to inhibit the clutch from being fully disengaged despite the presence of the signal from the shift lever switch, if the engine output torque is not smaller than the reference value.

Abstract: A power-assisted gear shift mechanism for a manual transmission includes a lateral casing mounted on a transmission housing, a first lateral shaft rotatably mounted within the casing and being operatively connected to a manual shift lever to be rotated in shifting operation of the shift lever, and a second lateral shaft in the form of a hollow shaft rotatably and axially slidably mounted on the first lateral shaft and being operatively connected to the manual shift lever to be axially moved in selecting operation of the shift lever, the second lateral shaft being integrally provided with a shift-and-select lever which extends into an interior of the transmission housing to be selectively engaged with a plurality of shift heads in axial movement of the second lateral shaft.

Thus the cutting blade horizontal velocity can be made to match the velocity of the material.

Abstract: Rotary shaking culture measuring method and apparatus characterizes in that culture tubes are disposed radially and at equal intervals in the circumferential direction, and an inclined turntable is disposed at a predetermined angle of inclination with respect to a horizontal reference plane, a central shaft of the inclined turntable serves as a driving shaft whereby a turning motion in a continuous or intermittently indexing form is imparted to the turntable. In addition, the culture tubes revolve along an inclined circular orbit described by such turning motion, and the substance being cultured within the tubes is shaked and cultured by a reciprocative motion of inertial resultant force of centrifugal force and gravity. Furthermore, in a certain position of the turntable the growth of the substance being cultured within all the culture tubes is measured with the lapse of time by a signal obtained at every fixed cycle.
