Title: Controlling equipment of servomotor
Inventor: HASHIMOTO ATSUSANE
IPC: H02P29/00
Filed: 1992-06-02
Abstract: PURPOSE:To suppress fluctuation of an output torque both for a motor for which a U-phase interphase voltage is synchronized with a U-phase CS signal and for a motor for which a U-phase line voltage is synchronized with the U-phase CS signal. CONSTITUTION:An electrical angle corresponding to a commutation signal (d) is obtained by an electrical angle determining part 11, while a U-phase edge of the signal (d) is detected by an edge detecting part 12 and an electrical angle corresponding thereto is abtained. Moreover, an electrical angle offset corresponding to a phase difference between a U-phase interphase induced voltage and the phase U of the signal (d) is outputted by an electrical angle offset output part 13. An electrical angle initial setting part 14 sets in a counter 3 an addition value of the electrical angle of the electrical angle determining part 11 and the electrical angle offset when a power source is made, and moreover, an electrical angle resetting part 15 resets in the counter 3 an addition value of the electrical angle of the edge detecting part 12 and the electrical angle offset when the U-phase edge of the signal (d) is detected. A servomotor 1 is subjected to a drive control by a sine wave output from a sine wave output part 4 which is computed by using set values obtained in the above.

Title: Potential detector
Inventor: TODOKORO HIDEO
IPC: G01R31/305
Filed: 1982-08-16
Abstract: PURPOSE:To detect the potential of a grid by varying the voltage of the grid in the prescribed range, producing the average value of the outputs of photomultipliers in the prescribed range and increasing the dynamic range as required. CONSTITUTION:A positive potential 22 is applied to a semispherical grid 15 inside the position directly above a sample 5, thereby accelerating the secondary electrons 2 from the sample 5. The resultant potential of a DC voltage 10 and a high frequency triangular voltage 16 is applied to the semispherical grid 4 at the outside. When a sawtooth wave voltage B is applied to the sample 5, the grid 4 indicates a characteristic curve 20 which has a width. When the secondary electrons 3 which have passed the grid 4 are detected by a detector 12 and amplified by an amplifier 13, an output 17 superposed with AC component can be obtained. When high frequency AC component is removed through an LPF14, a sawtooth wave signal 18 which reflects the voltage of the sample can be obtained, and the average value of the signal is obtained. When the potential of the grid 15 is thus fixed and the potential of the grid 14 is fluctuated by the high frequency triangular wave voltage, the linear part of the output voltage can be increased, thereby remarkably improving the dynamic range.

IPC: G11B5/31
Filed: 1992-06-02
Abstract: PURPOSE:To inhibit an interlaminar insulating layer from protruding even when magnetic films are worn in a magnetic head by the sliding of a tape and to prevent the reduction of output due to spacing loss and the damage of the tape and the head due to soft powder produced by wear by forming the insulating layer with a material having lower wear resistance than the material of the magnetic films.

Title: Application of protective tape
Inventor: MATSUHASHI SHIGEMITSU
IPC: B21D49/00
Filed: 1989-06-02
Abstract: PURPOSE:To simplify the whole of a device and obtain a total cost reduction effect by a method wherein the adhesive surface of a protective tape on an application roll and one side surface of a metal band are brought into contact, and the protective tape is continuously applied on the surface of the metal band by utilizing a pressing down force by its own weight, which is generated by the weight of the metal band. CONSTITUTION:A jamming roll is eliminated, and the adhesive bonding force relies upon the weight of a metal band 1. Between the running metal band 1 and an application roll 4 which rotates accompanying with the metal band 1, a protective tape 2 is inserted to feed, and the top surface of the application roll 4 is pressed by the own weight of the metal band 1, and the protective tape 2 is applied and bonded to the surface of the metal band 1 by its own weight pressing down force. When a span between positions P, Q becomes longer, the own weight of the metal band, which is added to the application roll 4, becomes greater, and the pressing down force for bonding is increased. When the span between positions P, Q becomes shorter, the pressing down force becomes smaller. Therefore, the most suitable pressing down force for bonding of the protective tape 2 can be freely selected, and optimum conditions can be easily set.

Title: Video reproducing device
Inventor: KITAHARA YOSHIHISA
IPC: G10K15/04
Filed: 1991-06-13
Abstract: PURPOSE:To prevent sounds from being muted by a television receiver in the state of reproducing no image. CONSTITUTION:When a video head does not execute reproduction and a reproducing video circuit 17 does not output the video signal, a pseudo vertical synchronizing signal (i), similar to a vertical synchronizing signal at a video signal (d) is prepared by a pseudo vertical synchronizing signal generation circuit 51, led out to a video signal output terminal 18 and led out to an RF module 15. Since a vertical synchronizing signal detection circuit 33 detects the synchronizing signal from sounds from a tuner 32 and from pseudo vertical synchronizing signals f2-i2, a mute circuit does not output a mute signal (h). Thus, an audio video circuit 34 selects either an audio signal f2 from the tuner 32 or an audio signal (b) from a voice output terminal 16 and makes a loudspeaker outputs it as a voice.
