  • Publication number: 20070229245
    Abstract: The invention provides a stop lamp lighting controller able to improve durability of a relay while unnecessary automatic turning on and off are avoided. A stop lamp is lit through a main line at a gentle braking time. At a sudden braking time, the stop lamp is switched on and off by disconnecting and connecting the main line in a predetermined period. At a breakdown time of the main line, the main line is switched to a subline and a lighting function of the stop lamp is secured. The main line is formed when both a first relay and a second relay are in a de-energizing state. The main line is disconnected and connected by periodically opening and closing the first relay. The main line is switched to the subline by energizing the second relay.

  • Patent number: 6781840
    Abstract: Fastening members such as tapping screws and rivers having a shaft are used to fasten objects such as circuit elements, a circuit board and a casing to a target object such as a heat sink of a circuit unit. The target object has a uniform cross-sectional shape along a specified direction, having grooves formed over the entire length along this direction. The fastening members are passed through the objects to be fastened and inserted into these grooves perpendicularly to be affixed to the target object so as to fasten the objects to be fastened onto the target object.

  • Patent number: 6681650
    Abstract: Disclosed herein is a driving state switching unit with a synchro-mechanism which employs a synchro-mechanism to perform switching of a driving state. The switching unit is equipped with a first gear (32) and a second gear (33) coaxially disposed, a gear connecting member (34) axially movable so that the first gear (32) and the second gear (33) can be connected, and a synchro-mechanism (35) interposed between the first gear (32) and the second gear (33). By moving the gear connecting member (34) by an electric actuator (50), the first gear (32) and the second gear (33) are connected, while they are being synchronized by the synchro-mechanism (35). When this occurs, control means (102) controls a supply current to the electric actuator (50), and judgement means (102) judges synchronization of the synchro-mechanism (35), based on a change in the supply current value to the electric actuator (50).

  • Patent number: 6461269
    Abstract: A forward-speed/reverse-speed changeover mechanism 6, serving as a motive-force connection/disconnection mechanism, is accommodated into a housing member 8 fixed to a casing 1. To the forward-speed/reverse-speed changeover mechanism 6 an input end of a primary shaft 3 is connected. The housing member 8 rotatably supports the primary shaft 3 via a bearing member 11. On an imaginary line intersecting the primary shaft 3 perpendicularly and passing through the bearing member 11, a load-receiving element 1b, 8b is provided between the housing member 8 and the casing 1. The tension of a belt 17 is received by the load-receiving element 1b, 8b. As a result, it is possible to provide a bearing structure of a continuously variable transmission enabling holding the bearing members of the primary and secondary shafts at their regular positions against the tension of the belt and maintaining an optimum belt-alignment, thereby enhancing the durability of the continuously variable transmission.

  • Patent number: 6246564
    Abstract: An actuating device for a motor used in a power window of an automobile which can drive the motor reliably to open the window even when the automobile is submerged in water. This device has a simple configuration is relatively small and inexpensive. This activating device comprises a drive circuit for a motor which has first and second relays to allow electric current to flow so as to drive the motor in either the forward or reverse direction. The contact of the second relay, which drives the motor in one direction, is used in such a way that the contact forms a part of an electronic circuit for the magnetic coil of the first relay. When the second relay operates, the electric circuit for the magnetic coil of the first relay is closed off. This activating device can ensure that a power window will be opened even if the automobile is submerged, and the first and second relay are switched ON at the same time.
