Abstract: PURPOSE:To vibrate a rotary main spindle in the axial direction with the magnetic force and miniaturize a main spindle device by providing magnetic vibrating devices controlling exciting current changing devices so that the generated magnetic force of stators in each line has a difference between the stators and is economically changed. CONSTITUTION:A built-in motor 20 is constituted of a rotor 21 fixed to a rotary main spindle 30 and three stators 22A-22C fixed on the inner periphery of a housing 31. When synchronous three-phase AC is fed to the stators 22A-22C, the rotating fields generated on lines A-C are synchronously rotated. The three- phase AC fed to the stators 22A-22C is controlled by exciting current changing devices 41-49 so that the amplitude is changed in the constant cycle. The exciting current changing devices 41-49 are controlled by magnetic vibrating devices 40A-40C. The center of the synthetic magnetic force of the magnetic force generated on the lines A-C is moved in the axial direction with the lapse of time. The rotary main spindle 30 is vibrated in the axial direction when the center of the synthetic magnetic force is moved.

Title: Fault detection method for mca base station
Inventor: NISHIMURA NORIO
IPC: H04B7/26
Filed: 1988-02-24
Abstract: PURPOSE:To detect a fault of an MCA base station without disturbing a call of a mobile station during operation by using a monitor so as to always monitor the operating state of a C-channel and raising a call from a pseudo mobile station in the non-operation of the C-ch. CONSTITUTION:A monitor 1 monitors the state of traffic of the C-ch9 by a pseudo mobile station 8. When the C-ch9 is not used for a prescribed time, the monitor 1 makes a call from the pseudo mobile station 8. In this case, when a transmitter-receiver 6a1 is operated normally, a call signal is received by the transmitter-receiver 6a1 of the C-ch via the C-ch9 and reaches to the line controller 5. Then the line controller 5 seeks an idle ch and allows the transmitter-receiver 6a1 to send a ch designation signal of the idle ch to be sough. If the ch designation signal is not received after the call by the pseudo mobile station 8, the monitor 1 judges it to be fault by the transmitter-receiver 6a1 and sends the information of fault occurrence of the transmission-receiver 6a1 of the C-ch9 to the line controller via a MODEM 2 and a private line 3 and a MODEM 2.

Abstract: PURPOSE:To establish a point of time of generation of a pulse electromotive force with high accuracy independently of the level of a maximum peak of an AC input signal by generating a pulse electromotive force from a detection coil being a magnetism sensing element at a zero cross point of the AC output when the AC output of an operational amplifier is fed to an exciting coil of the magnetism sensing element generating the pulse electromotive force in response to the change in an external magnetic field. CONSTITUTION:Since a differential output of an operational amplifier 1 with an AC input signal Vs and a DC control signal Vd fed respectively to input terminals S, D has a waveform shifting a ground line G of the signal Vs toward a line Go and a point of time of a phase (x) in the AC input signal is a zero cross point between the differential output current and the Go, the pulse electromotive force E is induced at this point of time. In this case, since the point (x), that is, the zero cross point of the differential output is controlled properly to a desired point of time by varying the level of a DC control signal Vd, the pulse electromotive force is induced accurately at a required point of time. Then in applying the pulse electromotive force E to a gate of a semiconductor control element 5, such as a thyristor, the operation of a circuit 6 to be controlled is controlled at a proper timing as the trigger signal.

Title: Device for stabilizing frequency of light source
Inventor: TANAKA KAZUO
IPC: H04B10/67
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To unnecessitate to select the wavelength of a light source skippingly in a comb shape and to continuously and optionally select the wave length by detecting the phase difference between an optical signal that is inputted to a dispersion generator and an optical signal that is outputted from the dispersion generator and controlling the wavelength of output light of a light source so that the phase difference can be a prescribed reference value. SOLUTION: For instance, in a light source substrate CH1, a light source LD1 outputs modulated light. A convolutional signal generation circuit CW1 performs intensity modulation of output light of the source LD1 at a fixed angular velocity that is optionally set and outputs the optical signal of wavelength λ1 that undergoes intensity modulation to a dispersion generator 2. The generator 2 generates delay that corresponds to the wavelength of the inputted optical signal of the wavelength λ1. A phase difference detector P1 detects the phase difference between the optical signals of the wavelength λ1 before inputting and outputting it to and from the generator 2. The wavelength of output light of the source LD1 is controlled, based on the phase difference so that the phase difference can be a prescribed reference value.
