  • Patent number: 7327050
    Abstract: An electric steering lock device is configured with a control unit to operate a steering column lock between a steering locked state and a steering unlocked state. The electric steering lock device has a locking limit switch that turns on when a locking member reaches the locking stop position, and turns off when an unlocking command for the locking member is outputted. An unlocking limit switch of the electric steering lock device turns on when the locking member reaches the unlocking stop position, and turns off when a locking command for the locking member is outputted. The electric steering lock control unit determines that the locking limit switch or the unlocking limit switch has malfunctioned based on the state of the locking member.

  • Patent number: 7269924
    Abstract: A device and method of notifying operation of a vehicle closure member is disclosed having a door drive motor 9 for driving a vehicle closure member, mounted in a vehicle, between an open position and a closed position, a pulse encoder 6 detecting a closure position of the vehicle closure member, and a notifying unit 7 notifying a user of operation of the vehicle closure member, with control being executed to apply a motor brake on the vehicle closure member at a time instant t1, upon recognition of operation for reverse movement when the closure position detected with the pulse encoder 9 remains in an area-just-prior-to-fully-closed-position between a half-latch position and the open position, whereupon a buzzer is activated at a time instant t2 with the motor brake being terminated when the vehicle closure member remains in the area-just-prior-to-fully-closed-position.

  • Publication number: 20060028159
    Abstract: A device and method of notifying operation of a vehicle closure member is disclosed having a door drive motor 9 for driving a vehicle closure member, mounted in a vehicle, between an open position and a closed position, a pulse encoder 6 detecting a closure position of the vehicle closure member, and a notifying unit 7 notifying a user of operation of the vehicle closure member, with control being executed to apply a motor brake on the vehicle closure member at a time instant t1, upon recognition of operation for reverse movement when the closure position detected with the pulse encoder 9 remains in an area-just-prior-to-fully-closed-position between a half-latch position and the open position, whereupon a buzzer is activated at a time instant t2 with the motor brake being terminated when the vehicle closure member remains in the area-just-prior-to-fully-closed-position.

  • Patent number: 4883606
    Abstract: The present invention relates to a temper rolling oil which comprises:(A) a water-soluble cationic compound prepared by neutralizing a condensation product obtained by reacting the following compounds 1 to 3 with each other by heating:1. an aliphatic dicarboxylic acid,2. at least one amino compound represented by the following formulae (a) to (c): ##STR1## 3. a particular polyethyleneimine, with an oxoacid of phosphorus, (B) an aqueous rust preventive, and(C) water.The present invention is also concerned with a method of temper rolling which, comprises of conducting temper rolling at a reduction ranging from 0.5 to 30% using a dilute solution prepared by diluting a temper rolling oil of the kind as described above, so that the concentration of a water-soluble cation compound contained therein is 300 to 5,000 ppm.
