Abstract: PURPOSE:To stop a drive body in an arbitrary position by providing n-piece position detecting means which are displaced from each other by (360/2n) deg. according to rotation of the drive body and invert an output at each (360/n) deg. and (360(n-1)/n) deg., and interconnected in series. CONSTITUTION:When a signal is inputted from a control circuit, a motor 16 is run, and a rotor 19 is rotated in an annular recessed part 12 of a housing 10 through a reduction gear group 18.

Title: Power source device of traveling-wave tube
Inventor: HASHIMOTO KAZUAKI
IPC: H01J23/34
Filed: 1987-03-25
Abstract: PURPOSE:To enable the satisfying of protection requirements for a traveling- wave tube, by supplying an anode power source through a divider, which contains at least a switching element compared with a helix power source, and actuating the switching element in a constant voltage controlling mode at the time of a normal operation and shorting the switching element at the time of start-up, stop, or abnormal stop in the whole power source device. CONSTITUTION:At the time of start-up, stop, or abnormal stop in a power source device 1 of a traveling-wave tube 2, a stop signal is applied to a switch circuit 22 from a stop controlling circuit 27 which is operated by receiving signals from a sequence circuit 26 and detection circuits 19, 20, and 24. When a voltage is missing in any circuit except for an anode circuit, the stop controlling circuit 27 is operated to short the switching circuit 22 so that a voltage between a cathode and an anode is made zero. A response speed, from a time when the stop controlling circuit 27 senses stop conditions of the anode circuit, to a time when the switching circuit 22 is shorted, can be made 0.5 ms or less if the semiconductor switch is used. The traveling-wave tube 2 can be hence protected completely.

Title: Music selecting device for tape recorder
Inventor: SHIMAGAMI KAZUTO
IPC: G11B27/02
Filed: 1985-04-05
Abstract: PURPOSE:To avoid such a case where an unrecorded part of a long time is dubbed at the dubbing side by traversing rapidly a tape at the reproduction side when an unrecorded part of a fixed time is detected and at the same time by rewinding the tape by a prescribed amount at the recording side. CONSTITUTION:In a dubbing mode, the presence or absence of a reproduction signal given from a tape recorder of the reproduction side is detected via a reproduction amplifier 7 and a signal detector 10. Then an unrecorded part of a fixed time is detected by a microcomputer 2 to which the timer signal is supplied from a timer 11. Then mechanism control circuits 5 and 6 are controlled by the computer 2, and the tape recorder of the reproduction side is set under a rapid traverse mode. While a tape recorder of the recording side is rewound until a recorded part is detected. Thus the selection of music is carried out without dubbing an unrecorded part of a long time at the dubbing side.
