Title: Positioning controller
Inventor: KITAYAMA HIROYASU
IPC: H02P25/06
Filed: 1983-12-21
Abstract: PURPOSE:To perform the positioning control system of a linear motor having stable and high speed servo properties by switching the gain of an error amplifier between the case that a linear motor movable element is moved at the prescribed speed and the case that the element is moved at more than the prescribed speed. CONSTITUTION:A speed command signal in response to an error between a position command applied from a point P2 and a signal of a potentiometer 41 and a speed feedback signal are differentially compared at an addition point 28, and amplified by K1 and K2 times by error amplifiers 29, 30, respectively. The output of error amplifiers 29, 30 are fed through a switch 31 and a voltage/current converter 33 to a current controller 34. The switch 31 is shifted to the K1 side when the speed of the movable element of a linear motor is the prescribed speed or higher set by a level detector 32, and to the K2 side when the speed is the prescribed speed or lower set by the detector 32.

Title: Radio telephone set
Inventor: TATSUTA NORIHIRO
IPC: H04B7/26
Filed: 1984-11-16
Abstract: PURPOSE:To hold a telephone circuit only with the transmission of a pilot signal in a short time when a slave device is started by providing an FF which works on the detection outputs of the reception and pilot signals to a master device together with a relay which holds a gate circuit and a telephone circuit. CONSTITUTION:When a slave device is set under a calling state, a PL (pilot) signal generator 5 produces the PL signals for several seconds and modulates the carrier wave to transmit it to the master device. At the side of the master device, the carrier wave detected by a reception circuit 9 is applied to a signal detecting circuit 17. The circuit 17 produces the 1st control signal, and a diode 23 is turned on via an inverter IV22. Then the electric charge of a capacitor C24 is discharged and an FF 19 is reset. At the same time, the 2nd control signal of an L level is produced from a PL detecting circuit 18 via an LPF 10. Then a capacitor C26 is discharged, and the FF 19 is set to apply the signal supplied from a terminal Q to an NAND circuit 20. When the PL signals are discontinued, the 2nd control signal is changed to an H level. Then a relay 15 is actuated via the circuit 20 and an inverter IV21 for holding a telephone circuit. In a ring-off mode the relay 15 is cut off with cut-off of the carrier wave and the holding state of the telephone circuit is released.

Title: Magnetron device
Inventor: MURATA MASAHIKO
IPC: H01J23/12
Filed: 1984-11-16
Abstract: PURPOSE:To closely couple a pair of yoke pieces by caulking by forming a pair of extruded ears which gradually becomes thinner as it comes to the end, bending the band region into the recessed portion of side wall, allowing said region to bite into the area between extruded ears. CONSTITUTION:The first and the second yoke pieces 1, 5 are combined and thereafter the band region 4 is bent inward. Thereby, it is located on a pair of extruded ears 8a, 8b of the band region 4. At this time,it is desirable that a pair of extruded ears 8a, 8b enter a little into the slot 3. Thereafter, when the intermediate part of band region 4 is bent, the intermediate part of band region 4 bites between the extruded ears 8a, 8b and the caulking terminates. Since the extruded ears 8a, 8b are formed in such a way as gradually becoming thinner as it comes to the end, the side wall open end edge of yoke piece 1 is strongly attracted toward the side wall of yoke piece 5 during said biting process, both yoke pieces 1, 5 are integrally coupled under the condition that these are closely in contact with each other.

Abstract: PURPOSE:To obtain an output signal with desired noise reduction and less waveform deterioration by providing noise reduction operation comprising a feedback means to a feed forward means of the noise reduction used in a conventional system. CONSTITUTION:A limiter 10 is a limit means limiting the amplitude of an output component Sc' of a subtractor 3, a coefficient device 11 is a coefficient means setting an output component of the limiter 10 to a coefficient K3, and a subtractor 12 subtracts an output component from the coefficient device 11 from the input original signal (video signal) Si from an input terminal 1. In adding the circuits as above, an LPF 2 being an extraction means receives an output signal of the subtractor 12. Thus, a large noise reduction effect comes from the low frequency side, and the residual noise just after edge at large amplitude is reduced and high waveform reproducibility is attained by the noise circuit.
