    摘要: The present invention provides a novel method for absolute asymmetric synthesis by irradiation with circularly polarized light, which comprises providing a photochemically reversible reaction system in which the starting material is a mixture of enantiomers or diastereomers not photochemically or thermally converted into each other; and irradiating the reaction system with right- or left-circularly polarized light to excite the starting material alone or both of the starting material and the product, thereby concentrating one of the enantiomers or diastereomers in the starting material and one of the enantiomers or diastereomers in the product that corresponds to the enantiomer or diastereomer not concentrated in the starting material.

    摘要: A disk playback device holds a disk in a playback position. A turntable moves toward the disk to a raised position where its support surface is adjacent a back of the disk. A spindle inserts through a center hole of the disk to align the disk with the turntable. A clamper is held above the disk on a side of the disk opposite the turntable. The clamper is supported close enough to the disk that when the turntable is in the raised position, a magnet in the turntable exerts a substantial force on a piece of ferromagnetic material in the clamper. When the clamper is released it clamps the disk to the turntable. By bringing the clamper and turntable to the disk rather than moving the disk toward one or the other, no space is required for the displacement of the disk in a direction perpendicular to its surface. The clamper is supported by a pair of holders, slidable in a direction parallel to the surface of the disk. Wedge-shaped surfaces on the holders engage a flange on top of the clamper to lift and hold the clamper above the disk. If a disk is misaligned with the spindle when the turntable is brought to the raised position, the disk is pressed against the clamper. The clamper in turn presses against inclined surfaces of the holders causing the holders to spread apart. The spreading is detected to invoke a control routine to correct the misalignment.

    摘要: A device for opening a shutter of a disc cartridge along with insertion of the disc cartridge into a holder of a recording and/or reproducing apparatus for performing recording and/or reproducing operation is disclosed. The device includes at least one arm member freely rotatable about a pivot provided at one end thereof and having at the other end a first engaging portion adapted to be in engagement with the shutter substantially during insertion of the disc cartridge. A guide means or a slot extending in an oblique direction between the cartridge inserting direction and a direction in which said shutter is slided to open is provided for guiding therealong a second engaging portion of the arm member during first-step advancement of the disc cartridge into the holder from an unloaded position to a half-loaded position, thereby rotating the arm member to open the shutter due to continued engagement thereof with the first engaging portion. The pivot of the arm member is supported by a sliding member and is sliding therewith in the cartridge inserting direction during second-step advancement of the disc cartridge from the unloaded position to a full-loaded position. A spring is connected between the arm member and the holder or apparatus for biasing the arm member toward a direction opposite to the cartridge inserting direction.
