Title: Monitor signal generating circuit for thyristor valve
Inventor: YAMADA KOJI
IPC: H03K17/73
Filed: 1986-02-17
Abstract: PURPOSE:To improve the uniformity of a light emitting diode driving current and to transmit wide-width pulses by using an inductor as a discharging circuit for a monitor signal generating circuit and forming a resonance circuit which drives a light emitting diode by using the inductor and a capacitor. CONSTITUTION:A high-voltage side ignition monitor unit 1 uses the inductor 20 as the discharging circuit for the capacitor 16 and the resonance circuit is composed of the inductor and a diode 19. A voltage that a main thyristor 4 is put in charge of is inputted to the unit 1 through a resistance 5. When the voltage changes from a forward voltage to a backward voltage, its current is supplied through the diode 15 and the terminal voltage across the capacitor 16 increases from the state wherein a thyristor 13 is off. At the same time, the burden voltage of the thyristor 13 also increases forward with the same value and when its voltage exceeds the voltage level of the diode 12, the thyristor 13 turns on, so that the current of a diode 11 is commutated to the thyristor 13. The diode 11, on the other hand, turns off and a capacitor 16 is discharged through the inductor 20, etc., so that the discharging current increases in a sine wave shape up to a peak value determined by the constant of said resonance circuit. Voltage monitor pulses generated as mentioned above are transmitted to a low-voltage side monitor device 3 through a light guide 2 and the pulse width is decided.

Inventor: HIBINO IKURO
IPC: H04M3/00
Filed: 1985-02-21
Abstract: PURPOSE:To prevent starting of communication in a stage in which only one set of communication channels are set by displaying an response of called terminal to a caller when response signals for two sets of calls are sent back from a digital integrated communication network to a terminal equipment that performs two sets of calls to utilize two sets of communication channels collectively. CONSTITUTION:When a terminal equipment 4 performs composite communication by voice and image with a terminal equipment 5, the terminal equipment 4 sends out a SETUP (V) signal for voice to set a communication channel for voice, and sends out a SETUP (I) signal to set a communication channel for image to a digital integrated communication network 1. At the same time, the terminal equipment 4 confirms that it is a call to utilize two sets of communication channels collectively, and when a called party made an response, starts counting functions of the number of CONNECT signals sent back from the digital integrated communication network 1. Then, after receiving the two sets of CONNECT signals from the digital integrated communication network 1, the response is displayed on the caller. Accordingly, starting of composite communication by the caller when only one communication channel is set can be prevented.
