    摘要: The present invention discloses comprising a cathode-ray tube having a fluorescent screen and a plurality of deflecting plates, a light sensitive means consisting of two or more photocells arranged so as to exactly confront the fluorescent screen of the cathode-ray tube, and an electric circuit connected to said light sensitive means and selecting a maximum signal out of signals applied from said cathode-ray tube, thereby detecting a position of signal. As the electric circuit connected to the light sensitive means and selecting the maximum signal, there may be employed an electric circuit which comprises operational circuits, relays and diodes and is adapted to select two signals in combination out of three signals produced on the signal source and provide an output of positive, negative or zero voltage, thereby operating any of relays through the diode to indicate the maximum signal, thereby improving the operational reliability and reducing the manufacturing cost.

    摘要: An intermittently driving circuit for a load such as a buzzer or a bell which by itself interrupts a current flowing therethrough. An SCR is connected in series with the load and a charge-anddischarge circuit including a capacitor is connected between a gate and a cathode of the SCR. The SCR is turned on after a charging period of the charge-and-discharge circuit for driving the load, while it is turned off after a discharging period of the charge-and-discharge circuit by the current interrupting operation of the load to stop driving of the load.
