IPC: G11B19/28
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To enhance the rotational accuracy of the output shaft of a motor by providing a control means for suppressing rotation of the output shaft based on the difference between a correction target r.p.m. and a detected r.p.m. SOLUTION: Every time when actual measurement r.p.m. data D13 detected at first through sixth r.p.m. detecting positions of the output shaft of a spindle motor 23 is acquired, a control section 28 generates a correction target r.p.m. data by canceling the detection error of the acquired actual measurement r.p.m. data D13 from a correction target r.p.m. data for the output shaft of a spindle motor 23. A rotation error data is thereby generated from the difference between the correction target r.p.m. data and a corresponding actual measurement r.p.m. data D13. Consequently, the control section 28 can generate rotation error data by enhancing the detection accuracy of the actual measurement r.p.m. data D13 based on the actual measurement r.p.m. data D13 and the correction target r.p.m. data thereby substantially eliminating the detection error.

Title: Optical wavelength multiplex transmission system
Inventor: SEKINE KENRO
IPC: H04J14/00
Filed: 1994-06-30
Abstract: PURPOSE:To suppress crosstalk between signal lights and to make a wavelength interval narrow by selecting a wavelength interval between output lights of an optical transmitter to be smaller than a minimum wavelength interval obtained by an optical branching means and making polarized directions of output lights of adjacent wavelengths nearly orthogonal to each other. CONSTITUTION:Two signal lights lambdai, lambdai+1 set at a smaller wavelength interval than a minimum permissible wavelength interval DELTAlambda0 decided by an optical branch means 5 are nearly subject to orthogonal control by polarized light control means 2-i, 2-(i+1) and the resulting signals are sent. When the one signal light lambdai in both signals is received by an optical receiver 7-i, since the wavelength interval (DELTAlambdai+1, i) of both signal lights is smaller than the minimum permissible wavelength interval DELTAlambda0 of the means 5, part of the signal light lambdai+1 is inputted to a polarized light separate means 6-i from the means 5 together with a receiver side signal light lambdai. Since the signal lights lambdai, lambdai+1 nearly have an orthogonal relation and only the component light in parallel with the signal light lambdai received by the means 6-i is extracted separately, the signal light lambdai+1 is eliminated. Thus, only the signal light lambdai reaches an optical receiver 7-i to suppress crosstalk.

Abstract: PURPOSE:To obtain driving force through utilization of heat transfer of a heat medium caused by the temperature difference of the same, by sealing a heat medium such as Freon in an expansible container. CONSTITUTION:When no temperature difference exist between the lower end and the upper end of a container 6, a hole 12 is closed by a valve 10, so that the inner space of a lowe chamber 16 and that in an upper chamber 17 are isolated from each other. When a certain degree of temperature difference is caused, Freon liquid in the lower chamber 16 is vaporized and pressure in the chamber 16 is raised resultantly, so that the container 6 is expanded at the lower chamber 16 whereas the upper chamber 17 is contracted since pressure in the chamber 17 is lowered through contraction of Freon vapor. When the upper chamber 17 is contracted a certain length, the valve 10 is depressed by a pin 11 and the hole 12 is opened, so that Freon vapor in chamber 17 and Freon liquid in chamber 16 are replaced with each other and the pin 11 is brought back to its original position where it closes the hole 12.

When input signals A, B are respectively turned to H levels and drive is started, both transistors(TRs) Q1, Q2 are turned on and voltage almost equal to the voltage Va of a power supply 1 is impressed to the collector side of the TR Q2. When the input signal A is turned to an L level and both TRs Q3, Q4 are turned off, a current I is allowed to flow into the coil Z through the resistor RL. When the input signal B is turned to the L level, both the TRs Q1, Q2 are turned off and the drive is allowed to end. Since the resistor for dividing the voltage Va from the single power supply 1 is connected, increase in the scale of the power supply system can be suppressed and two-step control can be realized.
