    • To provide a novel oscillating type actuator capable of securing a stoppage and holding when not energized, and producing a stable, responsive and highly durable oscillating arm even using a non-rare each magnet. The actuator is constituted by a housing; a shaft supported in the housing to be axially rotatable and has an output part to produce an output; a plate-shape oscillating arm that is fixedly supported to a shaft and has a swing surface perpendicular to the axis of the shaft, the oscillating arm performing a swing in a predetermine rotation angle range; two permanent magnets arranged along a swing direction of the oscillating arm and have pole faces different from each other on the swing surface; two magnet coils opposingly arranged to respectively face the permanent magnets; and a pair of interpoles arranged around a periphery of each of the magnet coils to opposingly sandwich one of the permanent magnets arranged side by side.

    • A wireless communication method for improving the transmission efficiency in an upstream communication in OFDMA-TDD system or the like. An upstream transmission timing control part (108), which employs this method, controls, based on the OFDMA-TDD scheme, the transmission timings of a mobile station (#p) and a mobile station (#M) communicating with a base station (100). The upstream transmission timing control part (108) acquires information about the propagation delay times τp and τM of the mobile station (#p) and mobile station (#M). When the propagation delay time τp is shorter than the propagation delay time τM, the upstream transmission timing control part (108) decides the transmission timings of the mobile station (#p) and mobile station (#M) such that the timing at which the base station (100) starts receiving symbols from the mobile station (#p) in an upstream section is earlier, by αp times an OFDM symbol length (L) (where αp is a natural number), than the timing at which the base station (100) starts receiving symbols from the mobile station (#M) in the same section.
    • 一种用于在OFDMA-TDD系统中提高上行通信中的传输效率的无线通信方法等。 使用该方法的上行发送定时控制部(108)基于OFDMA-TDD方式,控制与基站通信的移动台(#p)和移动台(#M)的发送定时 100)。 上游发送定时控制部(108)获取关于移动台(#p)和移动台(#M)的传播延迟时间taup和tauM的信息。 当传播延迟时间taup比传播延迟时间ττ短时,上游发送定时控制部(108)决定移动台(#p)和移动台(#M)的发送定时, 基站(100)开始在上游部分中从移动站(#p)开始接收符号的时间早于基站的时间(alphap是自然数) (100)开始从同一部分的移动台(#M)接收符号。
