Abstract:
To accurately move a pickup 31 along a radial line of an optical disc in an optical disc apparatus for recording signals on both sides of the disc or reproducing the signals from the both sides, the pickup 31 is mounted on a support base 30 coupled to transport means and movable by being guided by a U-shaped guide assembly 5 which is fixedly and accurately positioned on a chassis carrying a disc drive motor. The guide assembly 5 comprises a pair of straight travel guide portions disposed in parallel to each other on opposite sides of the plane of rotation of the disc, and a circular-arc guide portion interconnecting the two guide portions. When reproducing the recorded signals, the pickup 31 accurately reciprocatingly moves on the disc radial line along the straight travel guide portions, and when the reproduction position is changed from one side of the disc to the other side, the pickup quickly moves upward or downward along the circular-arc guide portion.

Abstract:
Uneven image density produced by photoreceptors, in which uneven electrification and sensitivity coexist, is limited economically and space efficiently. For each segment of the surface of the photoreceptor, individual memorizing of slope information K1 defining the slope of when a pixel gradation is approximately linear-transformed into exposure amount and, based upon K1 per segment, individual transforming of pixel gradation into the exposure amount (individual exposure amount transformation) is performed. The slope information which, with a reference electric potential Vs1 , matches the electric potential after the exposure of when the exposure amount, obtained by transforming a reference pixel gradation Is1 by means of the individual exposure amount transformation, is applied to the approximately-linear exposure property excepting the converging region to a residual potential VL, or to the exposure property extended by extrapolation operation, among exposure property g01 showing correspondence between the exposure amount and the electric potential after exposure per segment.
Abstract:
An oscillator for ensuring the phase relationship between two resonant circuits coupled by a coupling circuit. A first resonant circuit outputs two signals having different phases, and a second resonant circuit outputs two signals having different phases. The coupling circuit includes a plurality of inverters connected in a ring manner, and couples the first resonant circuit and the second resonant circuit such that the two signals output from the first resonant circuit and the two signals output from the second resonant circuit have different phases. A filter is connected to the input side of each of the plurality of inverters. With this structure, a signal output from each of the plurality of inverters has either a phase lead or a phase lag according to the phase characteristics of the corresponding filter, and thus the phase relationship between the first resonant circuit and the second resonant circuit is ensured.
