Abstract: An actuator control device includes an electrical control unit for detecting the present positions of output shafts of servo motors, and communicating with control circuits for driving the output shafts of the servo motors to target stop positions on the basis of the present positions thus detected. When it is judged that a present position of one of the output shafts thus receives is abnormal, the electrical control unit corrects the present position and transmits the corrected present position to the appropriate control circuit.

Abstract: The present invention relates to a grease composition for use in harnesses, which comprises a thickening agent, a base oil and additives, wherein the base oil comprises a polyoxyalkylene glycol ether and the additives comprise a quinoline compound and a benzotriazole compound. The grease composition is quite excellent in the corrosion resistance, the oxidation stability and the compatibility with materials such as olefinic elastomer.

Abstract: An electrical connector has a housing, a circuit board, harness terminals, and contact terminals. The housing has a hole and a lid. The circuit board is detachably disposed in the hole. If the circuit board is broken down, the lid is opened and the circuit board is removed from the hole. A new circuit board is then disposed on the terminals in the hole. The lid is closed so that the terminals are elastically deformed and the electrodes of the circuit board are electrically connected to the terminals.

Abstract: A wiring harness for connecting electrically between in-vehicle units includes a pitch ribbon cable having a plurality of bridge portions and a connector having a boss and a press-contact portion. Each bridge portion includes first, second and third notches. The third notch is engaged to another boss of the in-vehicle unit in case of assembling the pitch ribbon cable to the in-vehicle unit so that layout of the wiring harness becomes definite. The second notch is engaged to the boss of the connector in case of attaching the pitch ribbon cable to the connector. The first notch is engaged to the press-contact portion of the connector with using the second notch as a positioning reference so that positioning of the pitch ribbon cable becomes definite.

Abstract: In determining a starting point of a motor of an electric actuator during its initialization procedure, when a rotation angle sensor detects pulse signals in a certain initialization pattern, power supply to the motor is stopped by the control of a motor drive circuit. This electrical control of motor rotation enables the initialization procedure of the actuator to be carried out without using mechanical restriction means for locking purposes, and the influence of variations in the deflection amount of any stoppers is eliminated. The precision in determining the starting point in the initialization procedure is thus improved.

Abstract: In a car defroster which detects the clouding on the window glass by a sensor and blows conditioned air out from the defroster port to the window glass to remove the blur, an infrared sensor 1 is used as the sensor for measuring the surface temperature of the window glass, and the defrosting operation is carried out according to the measuring result. The infrared sensor is provided, for example, at a center of the ceiling of the passenger compartment, and consists of at least two sensor elements so that the temperatures of window glasses in a plurality of directions are detectable.
