Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a high reliability disk drive device also at high-speed rotation by reducing or counterbalancing a centrifugal force generated by an eccentric mass when the disk rotates. SOLUTION: A magnetic fluid insertion part 1b sealing up magnetic fluid 7 is arranged in a turntable 1, or a rotor part 2b of a disk motor 2, or a clamper 6. Further, when the disk 6 is not rotating, this device has such a structure that the magnetic fluid 7 is uniformly distributed by a force of attraction of a magnet 2c installed in the device or a newly installed magnet 9 even if the device is placed erectly. A centrifugal force generated in the direction of the disk surface due to eccentricity of the center of rotation is cancelled by the magnetic fluid 7.

Title: Radio system, base station and mobile station
Inventor: VOGEL MARTIN DR-ING
IPC: H04B7/26
Filed: 1994-02-04
Abstract: PURPOSE: To improve reception of a radio signal in a radio system by detecting the delay time between signals individually received from two antennas and adjusting the delay time between transmission signals to this detected delay time to transmit the signals from two antennas. CONSTITUTION: A signal transmitted from a mobile station through an antenna 9 is received by antennas 1 and 2 of a base station, and a detector 3 measures the delay time between two antenna signals. In following transmission, the base station 7 controls the delay time between transmission signals of a transmission equipment 8 in accordance with the delay time measured by the detector 3 by a delay time controller 7 to transmit the signals from antennas 5 and 6. The delay time between transmission signals is made equal to that between reception signals by this control, and two transmission signals are structurally superposed one over the other to increase the field intensity in a mobile station. Thus, reception of a radio signal is improved in the radio system.

IPC: H04B7/15
Filed: 1979-02-08
Abstract: PURPOSE:To secure the simultaneous performance for both the detection of the pilot signal and the demodulation of the order signal, by giving the balanced modulation to the order signal with the pilot signal used as the carrier and then detecting the modulation at the rear-step reception station. CONSTITUTION:The balanced modulation is given through balanced modulator BM to pilot signal P2 as the carrier via order signal 2 to be inserted to the repeater station. The balanced modulation wave is then applied to phase modulator PM to add the phase modulation to the transmission signal. And both pilot signal P1 inserted by transmitting device T and at the area near the pilot frequency and the balanced modulation wave inserted by modulator PM emerge at the output of receiving device R. Signals P1 and P2 feature the same frequency, and thus the output is equivalent to the amplitude modulation wave with signal P1 used as the carrier. As a result, order signal 2 can be obtained at terminal 4 via band pass filter BPF and detector D each.

Title: Operating method of magnetic separator
Inventor: ISHIKAWA HIROAKI
IPC: B03C1/02
Filed: 1982-02-01
Abstract: PURPOSE:To reduce the rising time of exciting current, and to make a separator compact and light, in the separator which excites by detecting an inclusion of magnetic pieces, by exciting with small electric power in ordinary running and exciting with large power when said piece is detected. CONSTITUTION:An exciting coil of a magnetic separator 12 is ordinarily excited by a small electric power kept within a range where a temperature rise of said coil is kept from exceeding an allowable temperature i.e. a preparation voltage VS, and an exciting current IS is supplied. When a magnetic piece mixed in raw materials on a moving conveyor 10 passes through a detecting means 24, a detecting signal S1 is transmitted to a controlling device to convert the voltage VS into an exciting voltage VF enough to attract the magnetic piece. Then the exciting current increases from the value IS in an ordinary state toward the IF corresponding to the voltage VF at the time of attracting state, and corresponding to said change, the value of magnetic field also increases from HS to HF. Thus the rises are curved as shown by real lines in the figure because of the delays caused by said increases. Accordingly, the attraction takes place after a short time t1 from the time the signal S1 is outputted, when the lower limit of magnetic field necessary for attracting the magnetic piece is put HL, and the current value necessary for exciting of HL is put IL.
