IPC: G11B7/09
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To provide a focus servo device capable of stabilizing focus lead-in by keeping constant the open-loop gain of a servo system. SOLUTION: The amplitude of an S curve is measured from a focus error signal S preliminarily with an S curve amplitude detecting circuit 7 prior to a focus lead-in; and the amplitude of the S curve is kept constant at the input point of the focus servo loop filter 9, by varying the gain of a variable gain amplifier 6 in accordance with the measured result. Consequently, even if an optical pickup 3 is driven by impressing a triangular wave voltage to a focus coil 12, the focus error signal S is provided with an amplitude equal to the maximum voltage (or the absolute value of the minimum voltage) while the open-loop gain of the servo system is kept constant; the focus servo is actuated when the focus position comes close to the face of a disk 1 with a voltage becoming zero; therefore, the focus lead-in can be stably carried out.

Patent JP-S5883820-A (JP)
Title: Control for absorptivity of electrochromic layer
Inventor: HORUSUTO BARUMAA
IPC: G02F1/17
Filed: 1982-10-28
Abstract: A continuous change in color is provided in order to control the absorptance of an electrochromic layer. The quantities of charge to be fed and removed by two sources of constant current are measured with a forward/backward counter. For decoloring processes, smaller amounts of charge are removed from the layer than are supplied to it for corresponding coloring processes. The quantities of charge removal for decoloring processes are, however, slightly greater than the quantities of charge which are theoretically necessary to obtain intermediate values with exactly the same absorptance, thereby assuring against destruction of the layer, even in case of numerous changes between different colorings. Preferred fields of use are lenses, particularly eyeglass lenses, filters and dimmable mirrors, using an applied electrochromic layer whose absorptance is varied.
