Title: Automatic controlling circuit for multiplication factor of avalanche photo diode
Inventor: INAO KIYOHARU
IPC: H04B10/00
Filed: 1981-06-17
Abstract: PURPOSE:To keep a multiplication factor to an optimum value in response to an input signal at all times, by forming a series circuit with an avalanche photo diode and a resistor, and suitably selecting an apply voltage for the circuit and a resistance value of the resistor. CONSTITUTION:An avalanche photo diode APD1 and a resistor 2 are connected in series and a prescribed voltage Vc is applied across the series circuit. An AC component of the voltage drop across the resistor 2 due to an output current i0 of the APD1 is inputted to an amplifier and outputted. A bias voltage of V=Vc-I0R (where; R is a resistance value of the resistor 2) is applied between the anode and the cathode of the APD1, and the current i0 is obtained with the multiplication factor determined with this voltage. The voltage Vc is made equal to a breakdown voltage of the APD1, and I0R is kept sufficiently smaller in comparison with the voltage Vc. Thus, the multiplication factor of the APD1 can always be kept to an optimum value in response to the input signal.

The heat of the heater H can be efficiently transmitted to an impregnated cathode member 5 or a sleeve 4 thereby so that the temperature of the heater H can be lowered, when the temperature of the impregnated cathode member 5 is set to similar thereto. This constitution can save the energy by reduction in power consumption, improve the reliability of a heater wire and an insulating film 2 by lowering of operation temperature, and elongate the life. In this case, pulverization of the grain size of the powder constituting the dark layer 3 can improve the heat radiation efficiency of the heater H.
