IPC: F02P5/15
Filed: 1979-06-11
Abstract: PURPOSE: To ensure safe operation of an internal combustion engine, by calculating fuel-injection controlling pulses by use of predetermined dummy flow voltages in case that some trouble is caused with the signal for measuring the flow rate of intake air.  
     CONSTITUTION: In case that measuring voltage Vs becomes equal to or smaller than Vrefl by reason of some trouble with the voltage Vs, a predetermined dummy flow voltage Vd is selected for calculating standard pulses Tp by use of the voltage Vd. On the other hand, if Vs is higher than Vrefl, voltage Vs is compared with the first reference voltage Vref2. Here, if Vs is raised abnormally and has become equal to or higher than Vref2, said dummy flow voltage Vd is selected to be used as parameter for calculating standard pulses Tp. On the other hand, if Vs is lower than Vref2, standard pulses Tp are calculated by use of flow measuring voltage Vs.

IPC: C23G5/04
Filed: 1994-03-18
Abstract: PURPOSE:To make cleaning action highly effective by providing a nozzle only below a cleaning tank and thereby smooth the flow of a cleaning liquid. CONSTITUTION:An actuator 8 is installed on the lid 2 of a cleaning tank 1 and a cleaning cage 10 is held by a holding frame 9 attached to a support plate 5 which is firmly fixed to a rotary shaft for the actuator. In addition, a cleaning liquid nozzle 11 which ejects a cleaning liquid toward the lower surface of the cleaning cage 10 and a current cylinder 13 encircling the periphery of the cleaning cage are provided. The current cylinder 13 is supported inside the cleaning tank 1, and is also attached to the holding frame 9. When cleaning, the cleaning cage 10 is caused to rotate back and forth by the actuator 8 with the ejection of the cleaning liquid from the nozzle 11, to cause the movement of the cleaning liquid in a peripheral direction. Thus the flow of the cleaning liquid descending in the cleaning cage is eliminated by the current cylinder 13 to increase the cleaning effect. Consequently, the flow of the liquid running toward the outer periphery from the center of the liquid level is generated so that oil and grease ascending to the liquid level are collected to the outer peripheral part of the liquid level.
