Title: Optical recording medium
Inventor: YAMAMOTO TORU
IPC: G11B7/246
Filed: 1988-09-02
Abstract: PURPOSE:To lower the production cost and to obtain an optical recording medium having rather high C/N (contrast) and long-life optical recording by applying polymer hollow particles on a substrate and melting them by heat with laser beam to read out changes in reflectance. CONSTITUTION:The medium consists of a substrate 11 and material 13 in which at least one layer of polymer hollow particles 12 having less than 1.2mum particle size is provided on the substrate. The refractive index of the material 13 is different from the inner material and the shell of the particle by 0.03 or more. In the initial state, laser beam reflects by scattering due to spherical surfaces and fluctuation of refractive indecis of particles. On recording, high power laser beam 22 irradiates the medium from the substrate side 11 to heat the medium higher than the m.p. of the hollow particles (softening point) to melt them. The molten particles 12 becomes homogeneous liquid on the substrate. Thereby, the irradiated region 21 by laser beam 22 becomes transparent. Thus, the optical recording medium with rather high C/N can be produced at low production cost.

Title: Image forming device
Inventor: KOBAYASHI SUSUMU
IPC: G03G21/14
Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To eliminate the malfunction of image forming processing due to unevenness of traveling of an endless belt by controlling the traveling speed of the endless belt on the basis of the velocity information filtered by a filter means. SOLUTION: A filter 9 eliminates a specified rotating frequency component, which is previously decided, among the angular velocity information from a FV converting unit 8. At this stage, since outer diameter of a driving roller 1 is set larger than the outer diameter of a driven roller 4, a low pass filter is used so as to eliminate a revolution number component of the driven roller as a high area side. A comparing unit 10 compares the speed signal, which is filtered by the filter 9, with the command speed signal 11 given from a main control unit (CPU or the like), and outputs the control signal to a motor driver 12 on the basis of a result of the comparison. The motor driver 12 outputs the driving signal to a driving motor 3 on the basis of the control signal given from the comparing unit 10. Consequently, unevenness of traveling of the endless belt due to eccentricity of the driving roller can be eliminated.

Abstract: PURPOSE:To prevent an operational margin from lowering due to the charge of a sense amplifier by controlling the driving ability of the sense amplifier in an antidependence of a source voltage even when external source voltages are different from each other in the same integrated circuit. CONSTITUTION:When the external source voltages Vcc, are different from each other in the same integrated circuit, by a reference voltage generation circuit 30, for optimizing the changing ability of a P channel sense amplifier 10, characteristics different from each other are imparted at the time of high/low voltage as a reference voltage of a sense amplifier driving circuit 20 driving the sense amplifier 10. That is, when the voltage Vcc is low, the reference voltage V. of the driving circuit of the amplifier 10 is high, and the charging speed of the amplifier 10 is increased. Further, when the voltage Vcc is high, the charging speed of the amplifier 10 is suppressed, and a malfunction, etc., due to the influence of a charging noise is suppressed. Further, a problem of a discontinuous point at a switching point between the low voltage and the high voltage is ignored on operation since the voltage VA is not changed rapidly, but is changed in analog.
