  • Publication number: 20050022734
    Abstract: The present invention provides an improved electrostatic coating apparatus that prevents imperfections in coating due to lumps of coating particles falling on the work piece. The electrostatic coating apparatus, which has multiple nozzles that spray electrically charged coating particles, has least one connecting member that connects the nozzles to each other, in such a way that the surface of the opening at the tip of the nozzle is inserted in a smooth interior surface of the connecting member. Although some of the coating particles discharged from the nozzles adhere to the interior surface, because the surface is smooth the coating particles can be prevented from concentrating locally into icicles that might fall onto the work piece.

  • Patent number: 6276197
    Abstract: A method for automatic control of a friction clutch (1) in a vehicle, which clutch is designed to be disengaged and engaged by a clutch actuator (3) under automatic control. An initial partially engaged clutch stroke position (Q1) and an initial clutch stroke position (P1) at which fluid pressure in the clutch actuator reaches a prescribed value are detected to obtain a difference (R1) between said two clutch stroke positions prior to initiation of automatic clutch control. The friction clutch wears as it is used. Therefore, both of the partially engaged clutch stroke position and the clutch stroke position attaining the prescribed fluid pressure value change while the automatic clutch engagement/disengagement control is being performed. However, the difference between these two clutch stroke positions does not change.

    Abstract: A starting apparatus for starting an engine only under constant conditions includes an electronically controlled clutch which is engaged or disengaged by an actuator in accordance with output signals from various detectors. The detectors sense a driving state, wherein a starter cut relay having normally-closed contacts is connected to an output terminal of an electronic control unit. One of the contacts of the starter cut relay is connected to one end of a relay coil for a starter relay. The other end of the relay coil is connected to a power source through a key switch. The other contact of the starter cut relay is connected to a non-grounded side contact of a neutral relay which is connected to the power source.
