Title: Electronic dynamic compensator of the servo device of optical pickup head
Inventor: YOU WEN-HAI
IPC: G11B7/09
Filed: 1998-12-14
Granted: 2002-04-11
Abstract: The present invention comprises an electronic dynamic compensator of the servo device of optical pickup head, wherein an position signal is inputted, transformed by a filter transfer function, and a compensation signal is outputted. When the processor sends a high speed rotational signal, the rotational motor proceeds the high speed rotational movements, the high speed rotational movement makes the switch conduct. Although the servo controller outputs the small signal gain, the switch conducts in response to the state of high speed rotational movement of the rotational motor, and the electronic dynamic compensator outputs the compensation signal to the summation nodes, the summation nodes outputs a high gain signal to the pickup head. For the servo controller, the equivalent mass, equivalent elasticity, equivalent viscosity and dynamic characteristics of the optical pickup head system it faces are all changed. The equivalent system dynamic characteristics can be regarded as the effect of optical pickup head plus the electronic dynamic compensator, wherein a very good system dynamic characteristics can be obtained by specifying appropriate poles and zeroes.

Title: Method and circuit for disabling a two-phase charge pump
Inventor: TERNULLO JR LUIGI
IPC: G11C8/08
Filed: 1999-02-08
Granted: 2001-01-21
Abstract: A circuit for disabling a two-phase charge pump includes a pump select circuit and a disable control circuit. The pump select circuit is configured to select one control signal from a plurality of control signals in response to at least one select signal. The selected signal is in effect provided to the disable control circuit, which also receives a pump disable signal. A voltage sensing circuit asserts the pump disable signal when the pumped voltage reaches a predetermined maximum level. While the pump disable signal is de-asserted, the disable control circuit in effect provides the selected signal to the two-phase charge pump as a pump control signal. However, when the pump disable signal is asserted, the disable control signal latches the current logic level of the pump control signal so that the pump control signal does not make transition while the pump disable signal is asserted. As a result, the two-phase charge pump is prevented from performing an extra pump cycle that would cause the pumped voltage to exceed the predetermined maximum level.

Title: Off-air phase lock technique
Inventor: GROFF DONALD
IPC: H04N7/10
Filed: 2000-05-24
Granted: 2002-02-11
Abstract: The proposed phase lock technique uses various feedback loops to lock the frequency and phase of a CATV modulator output signal to that of an off-air signal without directly measuring the output frequency. One embodiment includes a tuner for receiving the off-air signal and generating an intermediate frequency signal and a phase-frequency detector for comparing the frequency and phase of the intermediate frequency signal generated by the tuner with the frequency and phase of an intermediate frequency signal generated by the modulator based on a reference input signal. The output of the phase-frequency detector is used to control the reference input signal into the modulator and the reference input signal to the tuner such that the frequency and phase of the modulator output signal is locked to the frequency and phase of the received off-air signal. A second embodiment uses two tuners with a common reference frequency and a third embodiment eliminates the need for a tuner, using direct counting of the broadcast signal to derive the modulator reference signal.

Title: Waste water treatment method and waste water treatment apparatus
Inventor: YAMASAKI KAZUYUKI
IPC: C02F11/12
Filed: 2000-08-17
Granted: 2003-03-21
Abstract: In the waste water treatment apparatus, organic matter-containing fluorine waste water is treated in a reaction tank (3) into which biological sludge (31) and calcium-containing chemical sludge are introduced, thus making it possible to treat organic matters in the waste water by microorganisms contained in the biological sludge, and simultaneously to treat fluorine in the waste water by the calcium-containing chemical sludge. Therefore, since organic matters in the waste water and fluorine in the waste water, which differ in chemical properties from each other, can be treated with one reaction tank, it is no longer necessary to provide two reaction tanks, thus allowing the initial cost to be reduced. That is, this waste water treatment apparatus is capable of reducing the quantity of waste materials and reducing both initial cost and running cost.
