    • A method of switching a communication channel when a mobile station moves from one service area to another service area is disclosed. The mobile station determines a difference between the transmission phase of a frame synchronizing signal received from a first base station currently holding a communication channel with the mobile station and the transmission phase of a frame synchronizing signal received from a second base station expected to newly set up a communication channel with the mobile station. The mobile station sends phase difference information representative of the above difference to the first base station via the communication channel. The first base station having received the phase difference information transfers the information to the second base station, causing it to correct the phase of data thereof to be sent to the mobile station. This successfully implements soft handover while guaranteeing the phase synchronization of frames sent from the two base stations.
    • 公开了当移动台从一个服务区域移动到另一个服务区域时切换通信信道的方法。 移动站确定从当前保持通信信道的第一基站接收到的帧同步信号的发送相位与移动台之间的差异以及从预期新设置的第二基站接收的帧同步信号的发送相位 与移动台的通信信道。 移动台经由通信信道向第一基站发送表示上述差异的相位差信息。 已经接收到相位差信息的第一基站将信息传送到第二基站,使其校正要发送给移动台的数据的相位。 这成功地实现了软切换,同时保证了从两个基站发送的帧的相位同步。

    • A current detecting resistor is inserted in an H-bridge circuit constructed to cause the flow of a current to an inductive load in both forward and reverse directions by four semiconductor switching elements and flywheel diodes respectively connected in reverse parallel to the semiconductor switching elements. An inductive load driving method and an H-bridge circuit control device prevent an erroneous operation caused by noise generated at the current detecting resistor. When a current flowing through the inductive load is controlled by a detection voltage generated by the current detecting resistor, the value of the detection voltage is ignored immediately after the connection of the inductive load to a power source. There is no risk that an erroneous operation is caused by a rush current and/or a through current. When a power source regeneration is made to decrease a switching current, the inductive load is connected to the power source at a predetermined period and a current flowing at that time is detected as the detection voltage. There is no risk that the current becomes too small or the transfer to a steady is made while the current is large.
    • 电流检测电阻器被插入到H桥电路中,该H桥电路被构造成通过分别以与半导体开关元件反向并联连接的四个半导体开关元件和续流二极管在正向和反向两个方向上使电流流向电感负载。 感性负载驱动方法和H桥电路控制装置防止由电流检测电阻器产生的噪声引起的错误操作。 当流过感性负载的电流由电流检测电阻产生的检测电压控制时,在将感性负载连接到电源之后立即忽略检测电压的值。 不存在由冲击电流和/或直流引起的错误操作的风险。 当进行电源再生以降低开关电流时,感应负载以预定周期连接到电源,并且检测当时流过的电流作为检测电压。 电流不会太大或者当前的电流变大时,不会产生稳定的风险。

    • A rectifying device comprising of a SRMOS, an inductor, and a control circuit is disclosed. The SRMOS has a gate, a drain, and a source. The gate of the SRMOS is connected to the output of the control circuit. The inductor is connected to the drain of the SRMOS. The control circuit uses two sense traces for determining the voltage (or current) passing between the inductor (that is connected to the drain) and the source of the SRMOS. Upon sensing a forward characteristic (voltage or current), the SRMOS forward biases to allow current to flow through the SRMOS. Upon sensing a reverse characteristic (voltage or current), the SRMOS reverse biases to cut off any current flow. Hysteresis is used in setting the forward biasing threshold voltage and the reverse biasing threshold voltage for the SRMOS. In reverse biasing and forward biasing the SRMOS, V.sub.gs is stepped (or curved) controlled to avoid false turn ON/OFF of the SRMOS.
    • 公开了一种包括SRMOS,电感器和控制电路的整流装置。 SRMOS有一个门,一个排水沟和一个源头。 SRMOS的门连接到控制电路的输出。 电感连接到SRMOS的漏极。 控制电路使用两条感测迹线来确定电感器(连接到漏极)和SRMOS源之间的电压(或电流)。 在感测到正向特性(电压或电流)时,SRMOS向前偏置以允许电流流过SRMOS。 在感测到反向特性(电压或电流)时,SRMOS反向偏置以切断任何电流。 迟滞用于设置SRMOS的正向偏置阈值电压和反向偏置阈值电压。 在反向偏置和向前偏置SRMOS时,Vgs被控制(或弯曲),以避免SRMOS的错误打开/关闭。

    • A mechanism for rotating a vehicle seat body and a mechanism for restraining rotation of the seat body are partially shared, reducing the number of parts. The seat includes a seat body, a seat rotation mechanism, a gear forming member having a rotation gear, a drive gear meshable with the rotation gear, and an actuator for rotating the drive gear. The seat further includes a moving mechanism that relatively moves the drive gear and the gear forming member in a direction of a rotation restraint position such that the drive gear is placed in such a position so as to interfere with the gear forming member when the seat body rotates to a first position and when the seat body is urged to rotate in a direction of a second position while the drive gear is in such a position so as to not mesh with the rotation gear.
