Title: Trunking broadcast equipment
Inventor: KOYAMA JIYUNYA
IPC: H04B7/15
Filed: 1983-03-22
Abstract: PURPOSE:To prevent an interference wave from being retransmitted by detecting the interference wave and switching the characteristic of selectivity. CONSTITUTION:A part of an intermediate frequency signal of a receiving section 2 is branched and only the interference wave is extracted from BPFs 5, 6. Only the signal level is detected from the extracted upper and lower near-by disturbing waves at detectors 7 and 8 respectively, and Schmitt trigger circuits 9, 10 discriminate whether or not the disturbing wave level is a specified value or over. A detecting signal representing the presence of the interference wave is outputted at the output of an OR circuit 11 when the level is a prescribed value or over so as to change over intermediate frequency signal changeover switches 12, 15 and the intermediate frequency signal passes through a BPF14, and enters a transmission section 3. The characteristic of the BPF14 is a narrow band and even if the quality of broadcast is sacrified more or less, the interference wave is rejected. Since the transmission is performed with normal broadcast quality with the absence of the interference wave and the transmission is performed while rejecting the interference wave when the interference wave is incoming in this way, the retransmission if the interference wave is avoided even if the interference wave exists.

Title: Slow voice reproducing device for video tape recorder
Inventor: WATABE OSAMU
IPC: H04N5/783
Filed: 1989-02-28
Abstract: PURPOSE:To attain a voice reproduction with a little pitch fluctuation even in the case of a slow reproduction in the intermittent driving system of a capstan motor by sending a reproducing voice only when the rotation of the capstan motor is at a reference value approximate to the time of an ordinary reproduction or above, and stopping the sending in cases except for it. CONSTITUTION:By intermittently driving the capstan motor, the slow reproduction is executed. In the slow reproduction condition, the rotation of the capstan motor is detected by a speed detecting circuit 2, and the detecting signal is inputted to a muting control circuit 3. The muting control circuit 3 sends the reproducing voice when the rotational speed of the capstan motor exceeds a certain definite level approximate to the time of the ordinary reproduction, and the circuit 3 mutes the reproducing voice when the speed is at a certain definite level or below. Thus, at the time of the slow reproduction with the intermittent driving of the capstan motor, the slow voice reproduction with a little pitch fluctuation can be attained.
