    • A charging system for a vehicle battery comprises a voltage detecting circuit having at least one element, such as a Zener diode, having an impedance variable in accordance with a voltage from an auxiliary rectifier connected to the armature coils of the alternator of the system. When the generating voltage is low at the initial operating period, the impedance of the voltage detecting circuit is kept high, and thus the generated current from the auxiliary rectifier is all supplied to the field coil of the alternator without being consumed by a driving circuit of a charge-indicating lamp. As the voltage from the auxiliary rectifier exceeds a predetermined voltage, the impedance of the detecting circuit lowers to cause the driving circuit to energize the lamp. The voltage detecting circuit may be constructed of one or more than one Zener diode, or of a plurality of diodes connected in the forward direction. The driving circuit may be a relay or a semiconductor switch, and is driven by a current from either the auxiliary rectifier or the battery.
    • 一种用于车辆电池的充电系统包括具有至少一个元件(例如齐纳二极管)的电压检测电路,其具有根据来自连接到系统的交流发电机的电枢线圈的辅助整流器的电压的阻抗可变的阻抗。 当在初始运行期间发电电压低时,电压检测电路的阻抗保持高电平,因此来自辅助整流器的发电电流全部被供给到交流发电机的励磁线圈,而不被驱动电路消耗 充电指示灯。 当来自辅助整流器的电压超过预定电压时,检测电路的阻抗降低,导致驱动电路对灯通电。 电压检测电路可以由一个或多于一个齐纳二极管或者在正向连接的多个二极管构成。 驱动电路可以是继电器或半导体开关,并且由来自辅助整流器或电池的电流驱动。

    • A miniaturized printer wherein the duration of each print cycle, the sequence of printing operations performed in each print cycle and the time between each print cycle is controlled by a detecting arrangement. The detecting arrangement is adapted to detect the rotary position of a plurality of print rings having print characters circumferentially disposed therearound and for generating a character selection timing pulse for each of the available rotational positions of each print ring during a print cycle. The rotational position of each print ring corresponds to a print character circumferentially disposed about the print ring and, to this end, a print selection mechanism associated with each of the print rings selectively positions each of the print rings at respective predetermined print positions during each print cycle in response to the character selection timing pulses produced by the detection arrangement so that printing can be performed thereby. The detecting arrangement is further constructed and arranged to produce a stand-by signal representative of each print ring being positioned at a stand-by position at the end of each print cycle. The detecting arrangement further includes a shutter mechanism for preventing the detecting arrangement from producing a stand-by signal until a predetermined interval of time after the last of the character selection timing pulses are generated during each print cycle.
    • 一种小型化打印机,其中每个打印周期的持续时间,在每个打印周期中执行的打印操作的顺序以及每个打印周期之间的时间由检测装置控制。 该检测装置适用于检测具有周边设置在其周围的打印字符的多个打印环的旋转位置,并且用于在打印周期期间为每个打印环的每个可用旋转位置生成字符选择定时脉冲。 每个打印环的旋转位置对应于围绕打印环周向设置的打印字符,并且为此,与每个打印环相关联的打印选择机构在每次打印期间将每个打印环选择性地定位在相应的预定打印位置 响应于由检测装置产生的字符选择定时脉冲,从而可以进行打印。 检测装置进一步构造和布置成产生代表每个打印环位于每个打印周期结束时的待机位置的备用信号。 该检测装置还包括用于防止检测装置产生待机信号的快门机构,直到在每个打印周期中产生最后一个字符选择定时脉冲之后的预定时间间隔。
