Title: Clamping circuit
Inventor: TANAKA YOSHIKUNI
IPC: H03K5/007
Filed: 1986-01-14
Abstract: PURPOSE:To obtain a signal having a satisfactory S/N even in a very high transferring clock frequency by using a diode as the switching element of a clamping circuit. CONSTITUTION:For a switching circuit composed of resistances R1 and R2 and diodes D1 and D2, clamping pulses 11 and 12 are impressed and a non-conducting condition is kept so that the diodes D1 and D2 can be a verse bias at the time except for time t2. When the clamping pulses 11 and 12 are impressed so that the diodes D1 and D2 can be a sequential bias at the time t2, the diodes D1 and D2 come to be a conducting condition, the impedance comes to be low, the circuit of the channel of a clamping capacitor C   diodes D1 and D2 resistances R1 and R2 is closed and a clamping action is achieved. The voltage appears in which a voltage E(V) of the clamping pulses 11 and 12 is partially pressured by the resistances R1 and R2 and the diodes D1 and D2 in a middle point N with the diodes D1 and D2. Since the clamping capacitor C is connected to the middle point, a partially pressured voltage comes to be a clamping electric potential.

Abstract: PURPOSE:To print a pattern whose line width is fine, whose film is thick and in which the surface of a trascribed ink is flat by transcribing an organometallic ink nearly completely onto an object to be printed via a curing resin from the groove part in an intaglio and to form a circuit board having a fine pattern at low costs by baking the pattern.

Title: Muting circuit
Inventor: WATANABE KAZUO
IPC: H04B1/10
Filed: 1979-01-26
Abstract: PURPOSE:To eliminate a momentary increase in gain at the start of muting, by allowing a current by-pass transistor, constrolled by a mute signal, to operate in its unsaturation range. CONSTITUTION:Input signals (i) and (i ) supplied differentially are inputted to current Miller circuits Q1-Q4. Then, transistors Q10 and Q11 constituting a current by-pass circuit where their collectors are connected direct to emitters of output transistors Q2 and Q4, and forward diodies D1 and D2 which limit base input voltages are provided. Once a mute voltage is inputted, Q10 and Q11 try to conduct through buffer Q12, but since the base voltage is limited through the operation of D1 and D2, a current is absorbed without saturating. No variation in impedance viewed from Q2 and Q4 to Q10 and Q11 is caused, so that the gain of a current Miller circuit will greatly lessen without increasing.
