摘要： An optical encoder comprising a photointerruptor having light-emitting and light-receiving optical fibers and a rotatable pulse scale disposed in an optical path between both of the opposed end faces of the optical fibers so as to shut the optical path intermittently, thereby generating optical pulses in accordance with an angle of rotation of the pulse scale, in which the light-receiving optical fiber has a larger diameter and a greater numerical aperture NA than those of the light-emitting fiber. The light-emitting optical fiber may be replaced with a light-emitting device. Further, a reflector may be interposed in the optical path. Optical pulse signals indicative of an angle of rotation can be detected effectively and it is possible to facilitate the assembling or wiring operation and reduce the production cost.

摘要： An optical rotary encoder having a rotatable pulse scale having a row of code pattern with specific light-permeable or-deflection slits each for outputting a reference position signal and other light-permeable or reflection slits each adapted to reduce the amount of light for outputting an angular signal, both of the optical signals being photoelectronically converted and the waveform of the resultant electric signals being shaped based on threshold voltages into electric pulse signals indicative of a reference angle of 0.degree. and the accumulated angle of rotation, in which the circumferential width of each specific reference slit is made narrower than that of other slit so that the pulse width for angular position indicating of the angular pulse signal is always equal and constant for ensuring more accurate detection of the angle of rotation.

摘要： An automotive engine control system is provided for an automobile having a variable rotation speed engine which has a plurality of spark plugs served by respective spark plugs. The system includes an optical rotary encoder having a rotatable pulse scale having a row of code pattern with specific light-permeable or light-deflection slits each for outputting a reference position signal and other light-permeable or light-reflection slits each adapted to reduce the amount of light for outputting an angular signal, both of the optical signals being photoelectronically converted and the waveform of the resultant electric signals being shaped based on threshold voltages into electric pulse signals indicative of a reference angle of 0.degree. and the accumulated angle of rotation, in which the circumferential width of each specific reference slit is made narrower than that of other slit so that the pulse width for angular position-indicating of the angular pulse signal is always equal and constant for ensuring more accurate detection of the angle of rotation. As the engine rotation speed is sensed to speed up and slow down, by a sensor that is operatively connected with the engine, the optical rotary encoder varies igniting of the spark plugs.

摘要： A speed governor for a vehicle with an internal combustion engine senses an engine operating condition indicating the vehicle speed. When the vehicle speed indicated by the operating condition exceeds a prescribed speed, the cylinders of the engine are temporarily prevented from firing for short periods until the vehicle speed falls below the prescribed speed. In one form of the invention, a first sensor that senses a first operating condition is used to determine the vehicle speed under normal operating conditions. When the first sensor becomes inappropriate or malfunctions, a second sensor that senses another operating condition is used to determine the vehicle speed.

In a preferred embodiment, each of the second pulses has a width less than that of each pulse of the first signal, and each group of second pulses has a total sum of rising and falling edges which is different from that of each of the other groups. Preferably, the crank angle signal has a period in which the first signal is alternatively at a low level or at a high level.

摘要： An ignition distributor for an internal combustion engine has a cylindrical distributor rotor of synthetic resin, rotated synchronously with the revolution of the engine, and a rotor electrode radially and outwardly extending from the central portion on the upper surface of the rotor. A plurality of circumferential electrodes are disposed in the rotating locus of the rotor and are separated from the rotor electrode by a discharge gap. The rotor electrode has the shape of letter T a vertical portion of which is fixed to the distributor rotor and a horizontal portion of which opposes to the circumferential electrode, being in the shape of a circular segment. The surface of the rotor electrode horizontal portion opposing to the respective circumferential electrodes is formed to have a rugged or wavy profile comprising a plurality of peaks and the rugged surface is coated with a dielectric material such as silicon varnish to provide a low discharge voltage and reduced radio frequency interference in prolonged use.
