The output terminal Pi is brought to a high level even when both of the test wiring 1 and 2 are broken. Through these procedures, the trouble arising from the undesirable breakage of the regular wiring can be prevented.

Title: Transistor power amplifier
Inventor: SAKUNO KEIICHI
IPC: H03F3/189
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a power amplifier in which an effective gain control voltage range is wide. SOLUTION: The base of a transistor Tr11 for amplifying a power is connected through a bias resistance R13 with a gain control power source Vbb. Therefore, the transistor Tr11 for amplifying a power is directly biased from the gain control power source Vbb through the bias resistor R13, instead of a transistor Tr12 for driving a base until the transistor Tr12 for driving a base is turned on. Thus, an effective gain control voltage range enlarges by only the portion of an on-voltage between the base and emitter of the transistor Tr12 for driving a base.

Filed: 1991-09-10
Abstract: PURPOSE:To automatically switch the period of a mask signal by discriminating pseudo-synchronism or not with respect to an initial alarm mask circuit of multiple synchronous detection which detects synchronism of plural highways in time division. CONSTITUTION:One of plural highways 1-1 to 1-n is successively selected by a selector 2 and is connected to a synchronizing part 3 to detect and protect the synchronism.
