Title: Fuel nature sensing device of internal combustion engine
Inventor: OGITA TAMOTSU
IPC: G01N33/22
Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous judgement by a method wherein a fuel nature not influenced by an amount of fuel adhered to a wall surface before reaching a transient time can be detected. SOLUTION: As a fuel cut condition is established and a fuel cut is completed (S220), it is judged whether or not an accelerated state is attained from a completion of fuel cut within a predetermined time 10 (S260). In this case, if it is judged that an accelerated state is established, a varying amount ▵AF of the detected value of the air fuel ratio sensor is calculated (S270 to S300) and then a heavy quality fuel is judged in reference to the varying amount ▵AF (S310 to S320).  Upon shut-off of supplying fuel due to cut of fuel, fuel adhered to the intake air passage or the wall surface of the cylinder is sucked into the combustion chamber due to a negative pressure of the internal combustion engine, resulting in that an amount of fuel adhered to the wall surface is uniformly reduced and so the acceleration is carried out from a state showing a uniform less amount of adhesion of fuel at the wall surface so as to cause a judgement of the nature of the fuel to be carried out and then an erroneous judgement can be prevented.

Title: Method for judging polarity of shift speed detecting switch in automatic transmission
Inventor: KINOSHITA KENICHI
IPC: B60K28/10
Filed: 1988-04-30
Abstract: PURPOSE:To judge the polarity of a shift speed detecting switch automatically whichever it may be by storing the output level of the shift speed detecting switch simultaneously at the time of starting in an internal combustion engine. CONSTITUTION:When the starting of an internal combustion engine 2 is detected by the processing circuit 8 of an engine control device 1 based on signals from a revolution detecting means 6, the initial polarity of a shift speed detecting switch 3 at the time of engine starting is judged so as to let the output of it be received via an input circuit 5 so that the theoretical value is stored. And when a N range or a P range switch 3a or 3b is conductive, fuel feed is controlled to be improved in consumption because an engine is idling. However, when either of the switches is not conductive wherein a car is running, the output of torque is controlled to be increased. It is judged based on the output just after engine starting whether or not the shift speed detecting switch 3 is conductive. This thereby eliminates those actions such as the addition or alteration of input circuits by the model of the car, and the alteration of a program for the polarity judgement of switch input.

Filed: 1981-07-10
Abstract: PURPOSE:To start the arc without contact and to prevent the generation of spatters in the starting of the arc by supplying a starting gas of the spark discharge initiation voltage lower than that in the welding stage as a shielding gas. CONSTITUTION:When a welding start signal is emitted from a control circuit, an electric motor 6 runs at a low speed and feeds a consumable electrode 5 at a low speed toward the work 10. An electric power source 1 and a high frequency power source 2 generates output, and the voltage superposed with a high frequency voltage is applied between the electrode 5 and the work 10. At the same time, a solenoid valve 11 opens and a shielding gas for starting is released from a gas source 13 through a nozzle 9 to weld zones. When the spacing between the electrode 5 and the work 10 goes closer than the spark discharge initiation gap, the welding arc is generated. On detection of the generation of the arc, a solenoid valve 14 is opened and a solenoid valve 13 is closed. The feed speed of the electrode 5 is charged to the speed in the welding stage and the supply of high frequencies is stopped.
