    摘要: A transistor differential amplifier circuit includes a pair of NPN type amplifying transistors operated by a constant current source commonly connected to their emitters, and a pair of PNP type load transistors inserted in the collector circuits of said amplifying transistors, respectively. The load transistors are commonly biased with a constant voltage to operate within their saturation regions when input signals supplied on respective bases of the amplifying transistors are balanced, whereby pulse signals with a controlled duty ratio are obtained from the respective collectors of the amplifying transistors.

    摘要: An apparatus for measuring angular velocity is provided with a microwave oscillator, closed-loop waveguide and a microwave-detector. The microwave oscillator generates microwaves and the waveguide which may employ a magic tee as a part thereof separates the microwaves to propagate one and the other of separated microwaves clockwise and counterclockwise therethrough, respectively. The microwave detector mixes and microwave-detects one and the other of the separated microwaves propagated through said waveguide. When the waveguide is in rotary motion, frequencies or phases between the separated microwaves differ from each other in dependence upon the angular velocity and the microwave detector produces an output signal corresponding to the difference in frequencies or in phases between the separated microwaves. The angular velocity of the waveguide is measured by the use of output alternating signal component corresponding to the frequency difference between the separated microwaves or by the use of output direct current signal component corresponding to the phase difference between the separated microwaves.
