Abstract: PURPOSE:To restrain both stable and unstable oscillations by increasing the number of idling revolutions as the oscillations of a vehicle increases while increasing an engine outside load as the variation rate of oscillations increases. CONSTITUTION:In an internal combustion engine provided with an outside load device A for engine oscillations being load on the engine, an average value of oscillation strength (g) of a floor 9 showing stable oscillations from an output signal of oscillation detection sensor 16 of an oscillation detecting means B is obtained, and G expressed in the form of acceleration degree based on the average value of oscillation strength (g) as well as an variation rate  G of oscillation strength (g') showing unstable oscillations are obtained. Based thereon the increase degrees of idling speed and engine outside load capable of restraining both stable and unstsable oscillations most effectively are fixed. The idling speed is increased accordingly by an idling speed control means C as the oscillations of vehicle increase while the load of the outside load device A is increased by a load control means D as the variation rate of the oscillations of vehicle increases.

Title: Spark type anemometer
Inventor: SAKAI HIDEO
IPC: G01P5/18
Filed: 1983-04-19
Abstract: PURPOSE:To attain the miniaturization of the titled anemometer and the cost reduction thereof by simplifying the mechanism thereof, by measuring the flow speed of air directed to a microphone from an electrode by time difference to the time an impulse wave reaches to the microphone from the point of time when a spark is generated. CONSTITUTION:Pulse like high voltage is generated by a high voltage generator 1 and a spark is generated between electrodes 3a, 3b while a reset pulse R for resetting a digital timer T is generated slightly before spark generation. By this mechanism, the impulse wave generated by the spark propagates and arrives a microphone 4 after a T-time. The received impulse wave is sent to the digital timer 7 as an electrical pulse E through an amplifier 5 and a high pass filter 6. On the other hand, a spark pulse C is directly sent to the digital timer 7 to measure the time interval T of the spark pulse C and the shock pulse E. This time interval is a time required in propagating the impulse wave to the microphone 4 from the spark generating part 2.
