摘要:
The invention provides a screening method for chronic inflammation inhibitors or cancer metastasis inhibitors wherein, when a candidate substance as a chronic inflammation inhibitor or cancer metastasis inhibitor significantly inhibits binding between EMMPRIN and S100A9 or S100A8/A9, the candidate substance is evaluated as significantly suppressing chronic inflammation or cancer metastasis.

A servo circuit for use in an optical disk player or the like, which can track a disk having a large eccentrically without abnormal sampling of the RF signal produced as a result of scanning the disk. The servo circuit according to this invention comprises a first comparator for comparing RF signals from a pair wobbled pits on a optical disk and generating a difference signal indicating the level difference between the AF signals; a holding means for holding the difference signal for a predetermined period; a reference level producing circuit for setting reference levels having a predetermined width with the level of a previously sampled difference signal of the holding means as a center; a second comparator for comparing the level of a presently sampled difference signal of the first comparator with the reference level and outputting a first signal indicative of the comparative result; and a selector for selecting and outputting, as a tracking error signal, either the presently sampled difference signal and a second signal having a level within the predetermined width of the reference level in accordance with the comparative result. The presently sampled difference signal is selected when the level of the presently sampled difference signal is within the reference level and the second signal is related when the presently sampled difference signal is out of the reference level.

A circuit for computing a tracking error signal digitally. Under control of appropriate timing, input RF signals are latched in successive latches, and outputs of the latches are compared. The latch (9) whose output is D/A converted as a tracking error signal is controlled by suitable logic (25) to latch an output of a preceding latch (8), that output being used to provide input to the logic (25) through a threshold circuitry which includes adders (21,22) and comparators (14,15). The circuit takes advantage of servo patterns on surfaces of disks, particularly optical disks, to provide track count and on-track status. The digital approach removes the necessity for using capacitors or other types of sample-and-hold circuitry, and for controlling offset values.

An actuator drive circuit for driving a load using a single power supply. The current drive is not dependent on load impedance characteristics. Drive means provides a voltage across the first terminal and the second terminal during at input signal positive phase, and reverse voltage across the first terminal and the second terminal during a negative phase. A current detection resistor is connected in series with the load, and the voltage across the resistor is input to a differential amplifier. The amplifier output provides feedback to the drive means.

A pickup level control device for a system for reading out recorded information which has a pickup element producing a pickup output signal. The device detects a dc component of the pickup output signal and produces a level control signal. A voltage level of the pickup output signal is controlled in response to the level control signal produced by the dc level detection operation. The control of the voltage level of the pickup output signal is performed by a variable impedance element connected to a terminal of the pickup element, so that a peak level of an ac component of the pickup output signal is controlled below a predetermined level.
