Abstract: A disc playback apparatus incorporating a memory that stores data concerning errors or differences between commanded number of tracks to be traversed and the number of tracks actually traversed by an optical pickup actuated by a servo controller. The apparatus further includes a traversed track number computing unit computes the number of tracks to be traversed by the optical pickup when the optical pickup is moved to a track that corresponds to the address where the data to be read is stored and a correction processing unit performs a predetermined correction processing on the computed number of tracks to be traversed, taking into consideration the error data stored in the memory.

Abstract: An optical disc reproduction apparatus is provided for permitting appropriate automatic adjustment to a servo control system, particularly a CD and a DVD-ROM having a BCA.

Abstract: An altitude visibility information provision system and a flight obstacle recognition system of the invention are formed by a satellite image analysis and processing apparatus and an altitude visibility information preservation apparatus.

Abstract: A simple method of mass producing a plurality of solid electrolytic capacitor elopements can be performed to produce capacitors with reduced leakage current and excellent reliability. The method includes supplying a band metal, a first portion of which contains protrusions on which a dielectric layer, then a conductor layer are formed. A conductive polymer film is formed on the conductor layer by electrolytic polymerization starting from a conductive tape adhered on a second portion of the band metal. The conductive tape acts as a common positive electrode for polymerization and a plurality of electrodes connected independently to the protrusions as negative electrodes. Finally a plurality of capacitor elements are formed by laminating individual protrusions cut off from the band metal.

Abstract: An electric element of the present invention comprises a .pi.-conjugated macromolecular material which is liable to increase its conductivity by its excitation due to dielectric polarization, and a ferroelectric material disposed in the close proximity of said .pi.-conjugated macromolecular material so that polarization of said ferroelectric material in the presence of an electric field causes excitation of said .pi.-conjugated macromolecular material, thereby changing the conductivity of said .pi.-conjugated macromolecular material correspondingly with the strength of said electric field and resultantly controlling said conductivity. The electric element can be used as a d.c. or a.c. relay element, memory element, switching element, or any other active element.
