Title: Phase synchronous oscillation circuit for magnetic disk device
Inventor: MACHIDA TAKASHI
IPC: G11B20/14
Filed: 1990-07-03
Abstract: PURPOSE:To prevent phase synchronism from being disturbed at the time of switching a damping characteristic by transmitting two damping switching signals which have same amplitude and whose voltage polarities are opposite for switching the effective resistant values of a filter circuit. CONSTITUTION:When a charge pump high speed lead-in switching signal S7 is effective, the current values of discharge and attraction as against a phase difference current signal S4 are switched. A damping switch 5 transmits the damping switching signal S8 to a filter 3 for correcting the change of the damping characteristic by the switched current value and furthermore it transmits the damping switching signal S9 which has the same amplitude as the damping switching signal S8 and whose voltage polarity is inverted to the filter 3 for correcting the disturbance of noise at the time of switching damping. Thus, the switching of the voltage value of a control signal is transmitted as noise to an analog signal terminal and the occurrence of the disturbance of phase synchronism can be prevented.

IPC: G11B21/10
Filed: 1985-08-10
Abstract: PURPOSE:To attain the output of servo data in the form of pulse and to realize the position control of a head with high accuracy despite simple construction, by using a voltage controlled oscillator to obtain output signals corresponding to servo information and then converting said output signals in the form of the relative variance amount into the digital quantity by a reversible counter in response to the amount of the position to be controlled. CONSTITUTION:A voltage controlled oscillator VCO 17 oscillates with a frequency FVCO proportional to the voltage Vin of the voltage signal Svin supplied to a voltage control input terminal 17in from an amplifier 15. Thus the VCO17 is also used as a voltage/frequency converter. However, the start and stop of the oscillating operation of the VCO17 are controlled by the oscillation control signal SVCO applied to a control input terminal 17CON. Then the oscillation output signal SVCOUT of a variable frequency FVCO is produced through an output terminal 17out between the start and the stop of oscillation. An AND gate 19 transmits the oscillation output signal SVCOUT only when the front edge control signal SLEAD is kept at a 'low' logic level and supplied the addition input signal S19 produced from the output terminal to an addition input terminal UP of a counter 23.

Abstract: PURPOSE:To enable measuring gas temperture in wide temperature and pressure range without being affected by collision in the energy range that conventional laser light has by irradiating with laser light of two wave lengths and measuring the intensity of fluorescent light generating at a measured field in resonace to the irradiation timing. CONSTITUTION:Two absorption lines with the same electron upper rotation order and different lower vibration order which are excited by the being measured gas molecule exsting in a measured field, are selected. Laser beams with two wave lengths same as the absorption lines are projected on the measured field at a constant time intervasl and the intensity of fluorescent light generating in the measured field in resonance to the irradiation timing is measured. By this, the collision effect in each fluorescent line becomes to be the same owing to the same upper electron rotation order and as the result, the effect of the collision is relatively removed. Therefore, if the gas temperature in the measured field is determined by taking the ratio of the two measured fluorescent light intensities, measurement in wide temperature and pressure range become possible without being affected by the collision in energy range that conventional laser light has.
