    摘要： An electroless gold plating solution comprising an aqueous solution containing as ingredients (a) chloroauric (III) acid or a salt thereof or a sulfite or thiosulfate gold (I) complex salt as a gold source, (b) an alkali metal or ammonium sulfite or thiosulfate, (c) ascorbic acid or a salt thereof and (d) a pH buffer, characterized in that (e) a compound selected from 2-mercaptobenzothiazole, 6-ethoxy-2-mercaptobenzothiazole, 2-mercaptobenzimidazole, 2-mercaptobenzoxazole and salts thereof, and optionally (f) an alkylamine compound are further incorporated. The solution prevents the bath made up thereof from forming any precipitate during the storage and usage of the bath and the bath can be stably used for long periods of time. Furthermore, the bath gives a significantly high plating rate, which does not decrease even at high bath loads. Thus the bath renders it possible to plate a number of substrate items within a short period of time and also to perform thick plating within a short period of time.

    摘要： A power window apparatus is controlled by comparing present rotational frequency of a motor with a reference value selected depending on a present position of a window glass among plural reference values predetermined at every position of the window glass, supplying an electric current to the motor in the closing direction of a window when the present rotational frequency of the motor is larger than selected reference value, supplying the electric current to the motor in the opening direction of the window when the present rotational frequency is not larger than the selected reference value and the window glass does not arrive in a full-closed position, and cutting the current supply to the motor when the present rotational frequency is not larger than the selected reference value and the window glass arrives in the full-closed position.

    摘要： A four-wheel steering device for an automobile includes a main turning arrangement for steering main wheels, a subsidiary turning arrangement for sterring subsidiary wheels, and a control system including a motor having terminals thereon, first and second steering angle sensor arrangements for detecting first and second steering angles of the main the subsidiary wheels, respectively, and a control arrangement. The control arrangement is responsive to a state change of the first and second detected steering angles for determining the operating state of the control system. The control arrangement is operable when the control system operates normally to drive and control the motor and thereby the subsidiary turning means so as to steer the subsidiary wheels depending on the steering angle of the main wheels. The control arrangement is further operable when the control system operates abnormally to cut off the power source to the motor in order to converge the steering angle of the subsidiary wheels gradually to zero and also to short-circuit the terminals of the motor.

    摘要： A contact for a vacuum interrupter has excellent characteristics of high withstand voltage, low melt bonding property, large current durability and low chopping current and is prepared by uniformly distributing, in a copper matrix, two kinds of high melting point metal powders having a melting point of higher than 1450.degree. C. which have different particle diameters of (1) 80-300 .mu.m and (2) less than 30 .mu.m. The low chopping current characteristic is imparted by incorporating more than 10 wt. % of the high melting point metal powder. The high melting point metal powder can be selected from the group consisting of Cr, W, Mo, Ir and Co.
