Title: Jitter suppression circuit
Inventor: NARUMI KENJI
IPC: G06F1/04
Filed: 1992-07-29
Abstract: PURPOSE:To suppress jitter components impossible to be removed by a filter provided in clock signals. CONSTITUTION:A jitter component detection circuit 2 takes out only the jitter components in the clock signals CLK containing jitter components from an input terminal 1. A variable amplifier 3 sets the amplitude of the taken-out jitter components smaller than the amplitude of the clock signals CLK. A differential amplifier 4 finds the difference between the clock signals CLK and the output J of the variable amplifier 3 and generates difference signals S for which a jitter phase is corrected. A clock reproducing circuit 5 generates reproducing clock signals at an output terminal 6 with the zero-cross point of the difference signals S as time reference.

IPC: G11B5/02
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To simplify the constitution by utilizing a part of a magnetic field generating means as a rotor of a motor. SOLUTION: The device is provided with a magnet 22 magnetized over its circumference with P-pairs of poles (p: integer). This magnet 22 is used as a magnetic field generating means for a magneto-optical disk. Moreover, the beginning edge side of the magnet 22 is used as a rotor part and also the driving motor 50 is constituted of a stator part 51 having a coil 54 arranged on its outer periphery of the magnet 22. The direction of a current to flow into the coil 54 is controlled to rotate the magnet 22 over a prescribed angular range in the prescribed direction and to change a magnetic pole opposite to the magneto-optical disk. Data are recorded by irradiating light while forming a magnetic field from the magnet 22.  Since the magnetic field generating means for the magneto-optical disk is used as the rotor of the driving motor 50 as well and it is not necessary to prepare separately another driving motor for the magnetic field generating means, the constitution of a peripheral part of the magnetic field generating means can be simplified.

Filed: 1988-08-17
Abstract: PURPOSE:To reduce errors in grasping the potential characteristics of the surface of an image carrier as much as possible by providing a measurement control means which changes a grid voltage and measures the same location on the image carrier where bright and dark potentials are measured by means of matching the timing again. CONSTITUTION:The surface potential control sequence first changes a primary electrification grid voltage to three steps while a photosensitive drum 1 (image carrier) rotates. Then, exposure is turned on/off at each grid voltage step by laser beams, the photosensitive drum makes one revolution again. The same grid voltage is set to the surface position of the photosensitive drum where bright and dark potentials of three steps are measured previously by matching the timing. This time, the surface potential is measured by reversing the sequence of the laser's turning on/off. Thus, measured data doubles to enhance reliability.
