    • A control circuit of a tray loading apparatus determines, according to a disc size and a tray moving direction, a time during which to control the motor at a constant speed. When the specified time has elapsed after the motor was started, the control circuit produces a pulse-width modulated output to slowly lower the motor speed, eliminating impact noise when the tray strikes a stopper. This motor deceleration time is measured. When the measured deceleration time disagrees with a preset or previously detected target deceleration time, the difference is either added to or subtracted from a constant-speed motor operation time and the resultant value is taken as the next target time for constant-speed motor operation. In this way, by changing the time during which the motor is driven at a constant speed, any variations in the tray moving speed as might occur from varying loads on the motor are absorbed to keep the motor deceleration time and decelerating speed unchanged, thus making the tray motion smooth.
    • 托盘装载装置的控制电路根据盘尺寸和托盘移动方向确定以恒定速度控制马达的时间。 当电机启动后经过指定时间后,控制电路产生脉冲宽度调制输出,以缓慢降低电机转速,消除托盘撞击停止时的冲击噪音。 测量该电机减速时间。 当所测量的减速时间与预设或先前检测到的目标减速时间不一致时,将该差加到或从一个恒定速度的马达运行时间中减去,并将该结果值作为恒速马达操作的下一个目标时间。 以这种方式,通过改变电机以恒定速度驱动的时间,吸收马达上的负载变化所引起的托盘移动速度的任何变化,以保持马达减速时间和减速速度不变,从而使 托盘运动顺畅。

    • A motor control device for a radio control system is disclosed. The motor control device is mounted on an object to be controlled so as to adjust a control range in each of forward, braking and backing of the object. The motor control device is provided with a variable reference signal source for generating a backing reference signal and a comparator for discriminating a region of control element on a transmitter side by comparing a braking-backing command signal generated from a drive control circuit with the backing reference signal. The control range can be adjusted by adjusting a level of the backing reference signal of the variable reference signal source.

    • A hand held housing has a fluid chamber located therein which is divided into a first section and a second section. The fluid chamber is capable of holding a body of fluid. A passageway connects the first and second sections of the chamber. The second section of the chamber includes a membrane which is capable of moving a portion of the body of fluid through the passageway alternately back and forth between the first and second sections of the chamber. The first section has a flat front and rear plate which are parallel planar to each other. Located within the first section of the chamber between the front and rear plates is an essentially planar member having a plurality of parts which are articulatively joined together such that any one of the parts is movable with respect to at least one other of the parts. The member is movable in the first section in response to fluid movement through the passageway from the second section to the first section. However, it is incapable of rotating its plane with respect to the parallel planar of the front and rear plates.
    • 手持壳体具有位于其中的流体室,其被分成第一部分和第二部分。 流体室能够容纳流体。 通道连接腔室的第一和第二部分。 腔室的第二部分包括膜,该膜能够在腔室的第一和第二部分之间来回交替地移动通过通道的流体体的一部分。 第一部分具有彼此平行的平坦的前后板。 位于前板和后板之间的腔室的第一部分内的是具有多个部件的基本上平面的部件,所述多个部件铰接地连接在一起,使得任何一个部件相对于至少另一个部件是可移动的。 响应于通过通道从第二部分到第一部分的流体移动,构件可在第一部分中移动。 然而,它不能相对于前板和后板的平行平面旋转其平面。
