摘要： A valve driving apparatus has a second electric power source in addition to a main electric power source used in an internal combustion engine. The additional electric power source can be connected in series to the main electric power source so as to supply a high voltage to a solenoid used in the valve driving apparatus. The valve driving apparatus has an electromagnetic linear actuator for reciprocating a valve body of the electromagnetic valve apparatus so as to open or close the electromagnetic valve apparatus. The additional electric power source is provided separately from the main power source. A power source switching unit switches a voltage supplied to the electromagnetic linear actuator between the high voltage and a low voltage. The high voltage is generated by connecting the main electrical power source and the additional electric power source in series. The low voltage is generated by either one of the first electric power source and the second electric power source.

摘要： A mechanism for mounting a camera on an aircraft, such as a helicopter, comprising a camera housing for holding a camera and a camera support section including a linkage system for mounting the camera housing to the underside of the aircraft in a manner permitting movement between a retracted position proximate the aircraft fuselage and an extended position below the plane of the landing skids to facilitate 360.degree. photography. The mechanism includes a motor driven actuator for positioning the support section between limit positions and a manual back-up system in the event that the motor driven system becomes inoperable.

摘要： A liquid dropping apparatus for a helicopter includes a tank for containing a liquid therein for attachment below a helicopter body. The tank has a lower surface with a concave portion formed by concaving a wall portion and has a liquid discharge port opened on a side surface of the concave portion. A door is provided on a bottom surface of the concave portion of the tank to pivotally swing around a side thereof closer to the bottom surface of the concave portion, thereby freely opening and closing the liquid discharge port. Drivers are provided for driving the door to open and close.

摘要： An electromagnetic force generated in a valve driving apparatus is rapidly decreased when a valve body moves to a position close to the end of its stroke so that a shock generated when the valve body reaches the end of the stroke is reduced. The valve body is movable between opposite ends of its stroke so as to open and close a valve provided in an internal combustion engine. An electromagnetic coil generates an electromagnetic force exerted on the valve body. A current supplied to the electromagnetic coil is controlled in accordance with an operational condition of the internal combustion engine. The current flowing in the electromagnetic coil is rapidly decreased when the valve body approaches the end of its stroke.

摘要： An air-amount-first fuel-amount-second control apparatus for an internal combustion engine having an electronically-controlled throttle valve. The response characteristic of the throttle valve is stored, a target value of the throttle valve opening degree corresponding to the operating position of the accelerator pedal is calculated, the intake air valve closing time of the fuel injection cylinder is calculated in accordance with the engine operating condition, the time required for reaching a target throttle valve opening degree is calculated from the target throttle valve opening degree and the stored value of the response characteristic of the throttle valve, the throttle valve opening degree as of the intake air valve closing time is calculated from the calculated time required for reaching the target throttle valve opening degree and the intake air valve closing time of the fuel injection cylinder. A fuel supply amount constituting a target air-fuel ratio is calculated from the target air-fuel ratio and the intake air amount corresponding to the throttle valve opening degree as of the intake air valve closing time, and the fuel in the calculated amount is supplied to the engine fuel injection cylinder.
