  • Patent number: 5543672
    Abstract: A rotation detecting device for vehicle speedometers includes a housing, a magnetic induction device, and a magnetized rotor near the magnetic induction device. The rotor is connected through a coupling to a rotation source. A braking device forms a magnetic circuit between one end surface of the rotor and the housing, and brings the rotor into pressure contact with the housing by a magnetic attraction force generated in the magnetic circuit. Accordingly, a stable and proper braking torque can be applied against rotor vibration, to prevent a false output signal while idling. Furthermore, the amount of wear of a bearing for rotatably supporting a rotating shaft of the rotor can be reduced to improve durability of the rotation detecting device by reducing the braking torque during high-speed rotation of the rotor.

  • Patent number: 5204731
    Abstract: The invention relates to a method and apparatus for measuring the coordinates of a survey point. The apparatus uses a reflecting mirror at the survey point, a tachymeter for transmitting light to the reflecting mirror and for receiving light reflected from the reflecting mirror, first calculating means for calculating the coordinate values of two positions of the reflecting mirror, and second calculating means for calculating a coordinate value of the survey point from the coordinate values of the two reflecting mirror positions. In operation, the tachymeter transmits light to the reflecting mirror at the survey point wherein the reflecting mirror is locatable at two points present on a line passing through the survey point and which are separated from the survey point by predetermined distances.

  • Patent number: 5176461
    Abstract: A liquid painting instrument according to the present invention includes a neck portion of a cross-sectionally noncircular configuration provided on a wall having a passage hole that allows the neck member of the inner shaft to pass therethrough at a certain position in a circumferential phase while preventing the neck member from passing therethrough at other positions in the circumferential phase. The control wall is located at a position in front of the neck portion in the unknocked state. Projections are also provided on the front face of the neck member; each has a cam face that slides on the rear face of the control wall so as to displace the inner shaft rearward with respect to the fixed position where the valve is closed when the inner shaft is rotated preventing the neck member from passing through the passage hole.
