Abstract: In a near-infrared reflective substrate prepared by forming on a transparent substrate a near-infrared reflective film prepared by alternate deposition of low-refractive-index dielectric films and high-refractive-index dielectric films, there is provided a near-infrared reflective substrate characterized in that the transparent substrate is a plate glass or polymer resin sheet, that it is 70% or greater in visible light transmittance defined in JIS R3106-1998, and that it has a maximum value of reflection that exceeds 50% in a wavelength region of 900 nm to 1400 nm.

Abstract: The present invention relates to a radio wave-transmitting, wavelength-selective plate, which is characterized in that a layer composed of Ag fine particles is formed and that the central portions of the Ag fine particles contain an alloy (Ag alloy) formed of Ag and a metal which forms a homogeneous solid solution with Ag (hereinafter referred to as a homogeneous solid solution metal).

Abstract: Disk changer apparatus employs a commercially-available drive device that includes a sliding tray having an opening preformed therein. Disk elevator section has a portion movable through the opening of the sliding tray and thereby allows a disk to be transferred between a disk transport section and the sliding tray of the drive device utilizing the opening of the sliding tray.

Abstract: As a front panel of a disk changer apparatus is moved to an open position, a disk rack moving in response to the movement of the front panel operates to hold a plurality of disks in a staggered configuration. Such a staggered configuration of the disks allows a user to easily pick up and take out any desired disk from the disk rack.

Abstract: The invention relates to a frequency selective plate having a radio wave transparent property. This frequency selective plate includes (a) a transparent substrate; (b) a mixture layer formed on the transparent substrate, the mixture layer containing a mixture of a metal nitride and Ag; and (c) Ag particles formed on the mixture layer, the Ag particles being two-dimensionally distributed on the mixture layer and being separated from each other.

Abstract: A band comprising many beam portions and arcuate hinge portions formed integrally so as to be alternately arranged, a fitting force being obtained at least due to the returning force of the hinge portion so that the band can be expanded even with a small force and, in spite of the repeated use over a long period, the fitting force and winding action will not deteriorate and the band will not crack. The bands are connected symmetrically to both ends of a top band and are utilized as head bands for headphones.

Abstract: A pickup device for a disc player includes a pickup arm pivotally mounted at one end thereof for movement between upper and lower positions. The pickup arm is horizontally movable about the one end thereof. A drive device is responsive to a driving signal from a control circuit to drive an arm lifter for moving the pickup arm between its upper and lower positions. A brake device is also responsive to the driving signal for holding the pickup arm against the horizontal angular movement during its vertical movement.
