  • Publication number: 20140234560
    Abstract: This invention provides a fire-resistant reinforcement structure which facilitates work for improving fire resistance of architectural members such as pipes, a door, and a sash, a fire-resistant reinforcement architectural member, and a fire-resistant reinforcement method for an architectural member. A fire-resistant reinforcement structure is formed by pouring a thermally expandable fire-resistant material into a gap in and/or the interior of an architectural member, and characterized in that the viscosity of the thermally expandable heat-resistant material at 25° C. before the thermally expandable fire-resistant material is poured into the gap in and/or the interior of the architectural member is in the range of 1,000-100,000 mPa·s, and the thermally expandable fire-resistant material loses fluidity at 25° C. after being poured into the gap in and/or the interior of the architectural member.

  • Patent number: 8134453
    Abstract: An RF communications system including a controlled apparatus configured to receive a RF signal transmitted from a remote control transmitter on a channel that the controlled apparatus can receive, without providing a response signal to the remote control transmitter. The RF transmitting circuit unit of the remote control transmitter transmits RF signals on all of a number of selected transmission channels in a wireless frequency band, while the RF receiving circuit unit of the controlled apparatus stands by to receive an RF signal on a channel of the selected channels that has a relatively low electric field intensity.

  • Publication number: 20090267897
    Abstract: A remote control transmitter detects motion in a specific direction or in a rotational direction around a specific axis: The transmitter includes a battery placed on a bottom surface side within a case containing circuitry of the transmitter. The bottom surface side has a convex surface, with a center of curvature C coincident in the upward direction of the force of gravity above a center of gravity G of the transmitter. When placed on a flat surface, the transmitter assumes a stable orientation such that when the transmitter is grasped in order to perform a motion-based operation, it can be can be assumed that the vertical direction is the direction of the line joining the center of curvature C of the stable portion to the center of mass G, as an absolute direction for reference in detecting the motion operation.

  • Publication number: 20080169907
    Abstract: A remote control transmitter and a controlled apparatus that are paired by a pairing process that remotely controls the controlled apparatus. The operator initially uses the remote control transmitter to control the controlled apparatus so that it performs a specified operation, the remote control transmitter transmits RF packet data that contains a master ID, control data, and a status code that indicates a pairing start via an RF signal, and the controlled apparatus that receives this RF signal transmits RF packet data that contains a slave ID, the master ID, and a status code that indicates pairing ACK back to the remote control transmitter via an RF signal. The controlled apparatus further performs an operation based on the control data included in the transmitted RF packet data.
