    • A power throw circuit is provided within a keyboard-equipped apparatus such as an electronic calculator, an electronic timepiece etc. for determining whether a battery or batteries are connected between supply terminals therefor, whereby a power supply controller is not enabled to disconnect said power supply unless a power throw detection signal is developed from the power throw circuit. In response to the occurrence of the power throw detection signal from the power throw circuit power energy is automatically supplied from the power source to a power utilization circuit. In a preferred form, once the power utilization circuit has been enabled, and placed into the stable condition, the power throw detection circuit will no longer have any influence on the utilization circuit. In such stable conditions, the subsequent actuations of any key of a keyboard can control the power supply from the power source to the power utilization circuit. In another preferred form, the power throw circuit continuously provides the supply of power from the power source to the power utilization circuit without regard to the actuation of any key on the keyboard.
    • 在诸如电子计算器,电子钟表等的键盘配备的设备中设置功率投掷电路,用于确定电池或电池是否连接在供电端子之间,由此电源控制器不能够断开所述电源 除非从功率投掷电路产生功率投射检测信号。 响应于来自功率投射电路的功率抛出检测信号的发生,电力能量被自动地从电源提供给功率利用电路。 在优选形式中,一旦功率利用电路已经被使能并且被置于稳定状态,则功率投射检测电路将不再对利用电路有任何影响。 在这种稳定的条件下,键盘的任何键的随后的启动可以控制从电源到功率利用电路的电源。 在另一优选形式中,功率投射电路连续地提供从电源向功率利用电路的供电,而不考虑键盘上的任何键的致动。

    • An information read apparatus with tracking control system comprises a first closed loop and a second closed loop. The first closed loop performs high speed tracking control and feedback compensation for damping the tracking control system, with the aid of a means for detecting the tracking error without excess frequency dependency. The second closed loop performs precise tracking control with the aid of tracking error detection by wobbling the reading position on the information carrier in a direction traverse to the information track being read. The second closed loop is dominant only in the low frequency region. Since the second closed loop is negligible in comparison with the first closed loop near the cross-over frequency of the tracking control system, phase lag of the second closed loop is allowable about said cross-over frequency. Therefore, the wobbling frequency can be selected so low that the same actuator that controls the global reading position can be used for wobbling. In this way, the tracking control system performs both of high precision control and high speed control.
    • 具有跟踪控制系统的信息读取装置包括第一闭环和第二闭环。 第一个闭环执行高速跟踪控制和反馈补偿,用于阻尼跟踪控制系统,借助于一种用于检测跟踪误差的装置,而不会有过多的频率依赖性。 第二闭环借助于通过摆动在信息载体上的读取位置沿着所读取的信息轨道的方向进行跟踪误差检测来执行精确跟踪控制。 第二闭环仅在低频区域是主要的。 由于与跟踪控制系统的交叉频率附近的第一闭环相比,第二闭环可以忽略不计,因此关于所述交叉频率允许第二闭环的相位滞后。 因此,摆动频率可以选择得如此之低,使得控制全局读取位置的相同致动器可以用于摆动。 以这种方式,跟踪控制系统既执行高精度控制又实现高速控制。
