摘要： An electronically controlled fuel injection system in which terminating fuel injection is improved is disclosed. A reference position detector is adapted to generate a synchronizing signal at the predetermined angular position of an engine. A first computing circuit is connected to compute the required fuel injection interval in response to the synchronizing signal and a second computing circuit is connected to compute the rotation interval between two synchronizing signals successively generated. A further computing circuit is connected to compute the time interval which is equal to the difference between the rotation interval and the injection interval. The fuel injection is started when the time interval computed by the further computing circuit has passed after the generation of the synchronizing signal and is attained during the computed injection interval, whereby the fuel injection is terminated at the same position as the predetermined angular position.

摘要： An electromagnetic rotary driving device including a rotor of a permanent magnet arranged in a hole formed in a bored stator core block of a stator core, made from magnetic material. The air gap formed between the bored block of the stator core and the rotor in the direction parallel with the magnetic path in the stator core is relatively long, while the air gap formed between the bored block of the stator core and the rotor in the direction perpendicular to the magnetic path in the stator core is relatively short. In this device, the angle of rotation of the rotor is continuously changed by the current flowing through the coil of the stator without requiring a spring for return motion.

摘要： A rotary solenoid actuator for proportionally controlling the flow of fluid, such as air, in a pipe comprises a housing with a rotor rotatably mounted thereon. A stationary coreless coil for generating a magnetic field in response to a control current therethrough is mounted in the housing. A permanent magnet is affixed to a rotatably mounted shaft within the coil, and a return spring is attached to the rotating shaft. Due to low hysteresis in the coreless coil, there is a linear relationship between the control current and the fluid flow.
