  • Patent number: 7330104
    Abstract: A tire inflation pressure monitoring device includes transmitters for transmitting air pressure signals indicative of air pressures in tires, detected by respective air pressure sensors, and a receiver for generating a warning signal in accordance with the air pressure signals received from the transmitters. The air pressure signal transmitted from each of the transmitters includes an ID of the corresponding transmitter as an ID signal. When the receiver is in an ID registration mode in which the IDs of the transmitters are registered (S12), the transmitters are forced to transmit the air pressure signals, and if the number of the received air pressure signals is equal to a predetermined value, the receiver registers the IDs of the transmitters based on the ID signals included in the received air pressure signals (S20, S26).

  • Patent number: 7295102
    Abstract: When an alarm switch of a transmitter is given a long press carried out for one or more seconds in a timer-reset condition, a first alarm reversal signal is transmitted simultaneously with the setting (starting) of the timer. If the alarm switch is pressed within the set time of the timer regardless of a press time period, a second alarm reversal signal is transmitted, and the timer is reset. On a receiver side, the activation and deactivation of the alarm is alternately performed upon receipt of each alarm reversal signal.

  • Patent number: 7239835
    Abstract: An image forming apparatus includes a belt-shaped image carrier adapted to support a toner image: a transfer roller; a contact/separation mechanism, operable to bring the transfer roller into contact with the image carrier to transfer the toner image from the image carrier onto a recording medium and operable to separate the transfer roller from the image carrier after the toner image is transferred onto the recording medium; and a rotation applier, operable to apply a first rotation to the transfer roller in a state that the transfer roller is separated from the image carrier. The rotation applier and the transfer roller are mechanically separated from each other when the transfer roller is in contact with the image carrier. When the contact/separation mechanism brings the transfer roller into contact with the image carrier, a circumferential speed of the transfer roller is made coincident with a circumferential speed of the image carrier.

  • Patent number: 7173521
    Abstract: To issue a warning against an improper (a lowered) air pressure in accordance with a vehicle state and driver's presence/absence, the warning system includes air pressure measuring means for measuring an air pressure of a tire of a vehicle; air pressure judging means for judging whether or not the air pressure is proper; warning issuing means for issuing, if a result of the judgment is negative, a warning; and driver on-board judging means for judging whether or not a driver is on board the vehicle; and driver detecting means for detecting whether or not the driver is in the proximity to the vehicle. If the results of the judgments by the air pressure judging means and the driver on-board judging means are negative and a result of the detection by the driver detecting means is positive, the warning issuing means issues the warning outside the vehicle.
