Title: Agc circuit
Inventor: OOHASHI TAMAKI
IPC: H03G1/00
Filed: 1982-03-26
Abstract: PURPOSE:To obtain an AGC circuit excellent in the effect of attenuation, by  varying a capacitance value of a varactor diode corresponding to the change in  an AGC power supply and controlling an attenuation factor of an input signal between the unbalanced and balanced states of a bridge circuit. CONSTITUTION:The secondary side of an input signal circuit 3 by means of magnetic coupling is connected between opposing connecting points of a bridge circuit 1 comprising four capacitors C1-C4, at least one of them consisting of a varactor diode (e.g. C1 in this case). When an input signal is small, the AGC voltage is low and the capacitance value of the varactor diode C1 is the highest, 500 PF, then the bridge circuit is unbalanced, the input signal is outputted to the circuit of the next stage from a connecting point (c) without almost being attenuated via the C1. When the input signal is large, the AGC voltage is high, the capacitance of the C1 closes to 50 PF, resulting that the bridge circuit 1 reaches the balancing state, the signal output from the connecting point (c) closes to zero and the input signal is attenuated most largely.

Title: Small-sized electronic apparatus having game function
Inventor: YANAGAWA MIKIO
IPC: A63F13/55
Filed: 1981-03-31
Abstract: An electronic game apparatus having a display unit which is capable of displaying at least a series of numbers and decimal points the number of which is equal to the number of the series of numbers. Among the numbers, any number part of which is not displayed is defined as a target. The target is shifted toward one direction. With one of the function keys, a missile the shape of which corresponds to the non-displayed portion of the target is shifted toward a direction opposite to that of the target. When the non-displayed portion of the target is hit by the missile so as to complete the figure, the decimal point in an effective firing range (display frame or digit) where a missile digit and a target digit coincide disappears. Thus, points are made. The game continues until the missiles which have been given at the start of the game are used up. Points at each stage are added and final score is displayed when the game is over.
