IPC: H03G5/16
Filed: 1994-11-07
Abstract: PURPOSE: To provide a transmission output control circuit with which the maximum modulation degree of 100% can be attained at all times by eliminating the fluctuation of a modulation degree caused by the fluctuation of a gain due to the frequency and temperature change of an amplifier at an AME transmitter. CONSTITUTION: An output amplifying a modulating signal with an AGC-AMP 1 is inputted to a mixer 2, converted into an intermediate frequency by a locally oscillated signal 1 and passed through a band pass filter 3 and an SSB signal is generated. An output amplifying the locally oscillated signal 1 with a variable gain amplifier 4 is added to the SSB signal by a coupling capacitor 6, an AME signal is generated, and an AME transmission output is generated. The SSB signal is amplified by an amplifier 21, detected by a detection circuit 31 and inputted to a differential amplifier 30 and on the other hand, a carrier wave is amplified by an amplifier 25, detected by a detection circuit 32, inputted to the differential amplifier 30 and compared.  Then, a variable attenuator 20 is provided to vary the SSB signal with that compared output as a control voltage, and the modulation degree of an AME output signal is kept constant.

Abstract: PURPOSE:To suppress the variance of the tape width direction and to improve the stable drive of a magnetic tape by providing a fixed guide roll between a fixed guide and a guide roll set near a cylinder containing a lead part which holds a video head and guides the tape with control. CONSTITUTION:Fixed guide rolls 15 and 16 are set between guide rolls 3 and 5 and fixed guides 4 and 6 at the input and output sides near a cylinder 1 which holds a video head and performs record/reproduction. Then a magnetic tape 2 is wound round the cylinder 1 and driven. The width direction of the tape 2 is controlled by the rolls 15 and 16 at position near the tape input and output sides. Thus it is possible to suppress the variance of the tape width direction due to the minute variance of the reproducibility between both rolls 3 and 5 when the tape winding action is through. This improves the tape positioning accuracy and therefore prevents a tracking error, decrease the injuries of a tape edge, etc. and secure the stable drive of an extremely thin tape.
