IPC: G11B7/09
Filed: 1986-12-29
Abstract: PURPOSE:To obtain a supporting structure for objective lens holder which can shift the frequencies that cause the secondary resonance to a high frequency band while maintaining the sensitivity characteristics, by joining a flat plate part to a corrugated sheet in a structure where an objective lens holder is supported via the upper and lower sheets of support members set in parallel with thin hinge parts formed at both ends of the flat plate part. CONSTITUTION:A current flows to a focusing coil 8 and the up-down driving force is produced. Thus an objective lens holder 2 moves up and down by the up-down bending deformations of hinge parts 11b, and 11c of a support member 11. In such focusing control action, a honeycomb structure is obtained at the middle part of the member 11 with junction of a flat plate part 11a and a corrugated sheet 11e. Then the satisfactory rigidity is obtained despite a light weight. As a result, the deterioration of the sensitivity is avoided with an actuator an at the same time the generation of vibrations can be prevented since the resonance point moves to a high frequency band.

Filed: 1988-12-12
Abstract: PURPOSE:To provide excellent transparency by specifying the content of 3- methylbutene-1-polymer in propylene polymer and selecting suitable molding conditions. CONSTITUTION:After a propylene copolymer composition containing 0.003 - 0.5wt.% of 3-methylbutene-1-polymer having 303 deg.C or higher of melting point and 2 - 50sec of crystallizing velocity is extruded in a melted state by a T die, it is cooled to be solidified by a chilled roll at 40 - 100 deg.C to obtain a high transparency propylene polymer film propylene polymer. If the content of the 3-methylbutene-1-polymer is excessively small, the crystallizing velocity improving effect becomes insufficient, and its transparency is lowered. If it is excessively large, fish eye is generated, its transparency is reduced due to the 3- methylbutene-1-polymer itself or the excessively fast crystallizing speed, its cost is increased, etc., and it is not desirable.

A transmission station ST is connected to a pair of the signal lines L1 and L2 through an output capacitor CL1 and the current pulse signals of a prescribed carrier frequency are transmitted through the capacitor CL1 . Thus, even when the connection number of the transmission station is increased or decreased, a signal line potential is stably held.
