  • Controller for electronic key system
    Patent number: 7193334
    Abstract: A controller for an electronic key system including a portable device and an engine. When the ID code of the portable device cannot be authenticated, the controller instructs the driver of the necessary operations. When a transmitter circuit is transmitting a request signal but a receiver circuit does not receive a signal including an ID code matching the ID code stored in a memory, an authentication ECU authenticates a transponder code of the portable device with a stored transponder code to enable the starting of the engine. The authentication ECU displays the necessary operations for performing transponder code authentication.

  • Starter with overheat protection device
    Patent number: 7067934
    Abstract: A starter capable of reliably and safely cutting off or breaking a motor circuit when the motor circuit is subjected to an excessively large thermal load is disclosed. The motor circuit includes an intermediate member made of metal and electrically connected between a motor lead wire and a positive-side brush lead wire. The intermediate member has a fuse function that undergoes melting to cutoff the motor circuit when a thermal load excessively larger than that in normal use occurs in the motor circuit.
