Abstract: A clock matching apparatus for a data reproduction system includes a phase error detection unit which detects a phase error of a clock signal based on samples of a readout signal output by a sampler of the data reconstruction system. A phase-locked loop supplies a phase-matched clock signal to the sampler by compensating for the phase error detected by the phase error detection unit. The phase error detection unit includes an edge detection unit which detects a sampling instant for an edge sample among the samples of the readout signal. A difference unit generates a difference in timing phase between the edge sample and a sync level, the sync level being a reference signal level corresponding to a level of the readout signal at the sampling instants thereof and defined based on a partial-response waveform, the difference in the timing phase being output to the phase-locked loop as the detected phase error.

Abstract: There is provided an optical storage device that can position a lens carriage and objective lens even when position sensors for the lens carriage and objective lens are excluded in an effort to make an optical disk unit thinner. In the optical storage device, immediately after an optical disk is loaded in a main body, the cutoff frequency of a filter lying on a path of a reproduction signal is temporarily changed to a lower frequency. A spacing of sectors of the optical disk is detected using a signal sent from the filter. A type of an optical storage medium and a position of a current reproduction track are detected on the basis of the detected sector spacing and data stored in a memory.

Abstract: Disclosed is a video-camera imaging-system lens barrel which overcomes the problem of a four-lens-group-type video-camera imaging-system lens barrel, which has a complicated structure and large size and weight due to the large number of lens groups. In a so-called two-group-type lens system, a first lens group 2 and a second lens group 3, which are in focus in an imaging plane (CCD 4) for each zoom magnification at fixed subject distances .alpha.m and .beta.m, are controlled such that they move along zoom tracking curves 1.sub.1, 1.sub.2, 1.sub.3 and 1.sub.4 which represent the paths of movement of the respective positions of the first lens group and the second lens group.

Abstract: When an operating knob (12) is moved in an XA direction, an XB direction which is opposite to the XA direction, or a Y direction which is perpendicular to the XA and XB directions, coupling bars (44), (45) provided in a holder (20) which moves together with the operating knob (12) travel over slanted edges of push plates (34), (35), causing a pusher (22) to move in the Y direction. In other words, the pusher (22) moves in the same direction regardless of the moving direction of the operating knob (12). When the pusher (22) moves, a projection (33) formed at a far end of an elastic element (32) provided on the pusher (22) presses against a tactility-producing wall (40), resulting in an increase in force required for moving the operating knob (12).

Abstract: A method for collecting volatile organic substances from an off-gas containing moisture and volatile organic substances. The organic substances are removed from the gas containing the organic substances and the moisture by introducing the gas into an adsorbing tower filled with the adsorbents and being in the adsorbing process under a relatively low temperature condition. The gas is discharged outside the system as the gas containing the moisture but from which the organic substances have been removed. The organic substances are desorbed under a relatively high temperature condition in the regenerating process for the regeneration. The moisture is removed from the desorbed gas discharged from the adsorbent regenerating process in a dehumidifying tower filled with the moisture absorbent by the temperature swing method or pressure swing method.
