摘要： A power steering apparatus for being protected from mud or dust, or rainwater. A sub-steering unit is provided together with a torque sensor of the power steering apparatus used in a vehicle. A steering shaft portion includes an input shaft and an output shaft, each being rotatably supported. A torque sensor portion is connected for joining the input shaft and the output shaft with the torque sensor portion sensing an amount of torque. A power assist portion is engaged with the output shaft for assisting the steering based on the amount of torque sensed by the torque sensor portion and the like. A sub-steering portion is engaged so as to connect the input shaft with the output shaft while circumventing the torque sensor portion and reducing the amount of torque. The power steering apparatus includes a column cover for covering the sub-steering portion as well as the torque sensor portion.

摘要： A booster is constructed with a piezoelectric transducer including a combination of a primary side piezoelectric element and a secondary side piezoelectric element wherein input electrodes and an output electrode are provided in the thickness direction and length direction, respectively. The booster is contained in a plug cap. The plug cap covers one end of a spark plug. Using this arrangement, a primary voltage having a natural resonance frequency of the piezoelectric element or a waveform identical to a component waveform thereof is applied from a primary voltage generator to the input electrodes. At this time, the booster directly imparts a secondary high voltage from the output electrode to the spark plug by the piezoelectric effect, to generate a spark discharge in a discharge gap of the spark plug. This ignition system can be made smaller in size and weight at a low manufacturing cost.

摘要： An engine control device is provided for reducing the retrieving time of control data from sensors at high and low engine speeds. Control parameters from the sensors are converted into memory access parameters to a control map to recover the desired injection amount. The fuel injection quantity is calculated by retrieving fuel injection amounts using the memory access parameters as addresses and performing a four-point interpolation of the memory parameters. A previously retrieved value is used as a reference value to aid the determination of an updated memory access parameter so that the retrieving time can be reduced for high and low engine speeds.

摘要： To obtain optimum combustion of fuel in an internal combustion engine and prevent the occurrence of reverse torque therein, an ignition timing control system having a pulse generating circuit for generating first and second timing pulses corresponding to respective predetermined crank angles of the engine includes means for producing all essential signals and, hence, for setting maximum delay angle ignition timing, based on a reference which is the leading edge of the second timing signal, which edge is unaffected by unstable engine rotation as when the engine is started. To simplify and reduce circuitry, an ignition signal generating circuit and a reverse torque preventing circuit are integrated and adapted to perform both functions.

摘要： A fail detecting device for a rotation angle sensor, for detecting a fail of the rotation angle sensor even if the number of rotation angle sensors is one. A cam is configured to be driven to rotate in one direction by an electric motor to reciprocate a push rod. An output voltage of an angle sensor is set so that the region equal to or lower than a first predetermined voltage and the region equal to or higher than a second predetermined voltage higher than the first predetermined voltage are recognized as a dead zone. The elapsed time after the transition to the dead zone is measured by a timer and it is determined that the angle sensor is in the fail state if the output voltage corresponding to the dead zone is detected although the estimated time of the passage through the dead zone has elapsed.

摘要： To precisely detect the temperature of a power assist motor without using a temperature sensor and enhance an overheating protection function. A calorific value calculating unit calculates a calorific value based upon the difference between a calorific value by current supplied to a motor and the quantity of heat radiation. The output of the calorific value calculating unit is accumulated and an accumulated value is input to an accumulated value buffer. A cumulative value TS acquired by adding initial temperature T0 to a cumulative value Td is input to a ratio map of a target current value, ratio is read, and a target base current value is limited according to the ratio. The cumulative value TS used in the map is not an actual motor current value and is calculated based upon unlimited current acquired in an unlimited current calculating unit.

摘要： A sensor for converting a physical quantity into an electric signal and issuing the output is driven by a drive circuit which is driven by a drive signal issued from a 1-chip microcomputer. The 1-chip microcomputer judges fault of sensor function when the sensor output signal is out of a specified output range. Further, when stopping the operation of the drive circuit, if the sensor output signal does not coincide with a specific value, the 1-chip microcomputer also judges fault of sensor function. According to the invention, in the event of a trouble of sensor function allowing the sensor output signal to settle within an output range, such trouble can be detected.

摘要： To provide the driver with a driving feeling which faithfully keeps up with various running states of the vehicle and running requirements of the driver by finding an accommodation coefficient indicating a running state by fuzzy inference. A target rotational speed of the engine is set on the basis of the accommodation coefficient found during the previous step. The change-gear ratio of the nonstage transmission is controlled so as to result in the target rotational speed of the engine set at the immediately previous step. A transmission control unit includes an accommodation coefficient fuzzy-inferring control, a target engine rotational speed setting control and a change-gear ratio controlling member. Inputting the change-gear ratio R, the throttle opening O, the speed v of the vehicle and the change in vehicle speed per unit time (or the acceleration) G, the accommodation coefficient fuzzy-inferring control finds a rate of change A in accommodation coefficient A by using fuzzy rules set in advance. The target engine rotational speed setting control sets a target rotational speed NE of an engine on the basis of at least the accommodation coefficient A and the speed V of the vehicle. The change-gear ratio controlling member controls the change-gear ratio R of the non-state transmission to provide a rotational speed N of the engine equal to the target engine rotational speed NE.

摘要： Disclosed is an improved multi-pin type of water proof electric connector which is guaranteed free of shortcircuit between adjacent pin-and-contact piece connections even if water should invade to any pin-and-connector piece connection through the very small gap between the conductor and the insulation sheath of the wire by the capillary action. The electric connector comprises a male half having contact pieces and a female half having pin terminals in its cavity, and a seal member placed in the space which is to be formed between the outer surface of the plug housing and the inside surface of the socket housing when the male and female halves are coupled. The plug housing has a plurality of hollow protrusions each containing a contact piece, and the seal member encircles each of the protrusions, thereby sealing each pin-and-contact piece connection independently from adjacent pin-and-contact piece connections when the male and female halves are mated.
