Abstract: AN OPTICAL PICKUP INCLUDES A POLARIZATION COMPONENT SEPARATION ELEMENT WHICH IS FORMED AS A UNIT OR SINGLE PIECE OR BIRERRINGENCE MATERIAL. THE SEPARATION ELEMENT IS NOT LAMINATED OBVIATING THE NEED TO CAREFULLY MATCH THE OPTICAL AXES OF THE LAMINATED PIECES. MULTIPLE REFLECTIONS WITHIN THE BIREFRINGENT CRYSTAL WHICH COMPRISES THE SEPARATION ELEMENT IMPROVES THE SEPARATION AND RESOLUTION OF THE POLARIZED COMPONENTS WHICH ARE EXTRACTED FROM A LASER BEAM REFLECTED BACK OFF THE MEDIA SURFACE.

Abstract: An optical communications apparatus and method of using same in which optical coupling between an optical medium and a light emitter and a light receptor is achieved without any optical system therebetween. A minor axis of light transmission pattern on an end face of the optical fiber corresponds to the radial direction of the end face while a center C of the light emitter is displaced off from a center axis O, thereby providing improved optical coupling efficiencies.

Abstract: An apparatus for recording and/or reproducing a disc-shaped recording medium records and/or reproduces information signals on or from the recording medium having an information recording region for recording information signals and a table-of-contents region for recording at least the number data and the title data of the information signals recorded in the information recording region. The recording and/or reproducing apparatus includes a recording and/or reproducing unit and a display unit. Within the recording and/or reproducing unit, a plurality of disc-shaped recording media are disposed and arranged co-planarly in a side-by-side relation to one another. The recording and/or reproducing unit records the information signals on a selected one of the disc-shaped recording media and/or reproduces the information signals from the selected disc-shaped recording medium. The display unit, which has its control operation controlled by an output signal from an output signal of the recording and/or reproducing unit, has a first display region for displaying data recorded in the table-of-contents region and a second display region having the same display configuration as the arraying state of the disc-shaped recording media. The second display region is simultaneously employed as a display area for indicating the audio sound hearing position controlled by a sound field controller.

Abstract: An optical pickup and an optical recording medium reproducing apparatus smaller and more reliable than conventional optical pickups and optical recording medium reproducing apparatuses. These are provided with a one-dimensional metal grid which is formed so that the ratio h/d that the pitch "d" and the thickness of metal conductors "h" constituting the wire grid is about 0.1 or more, and also a group of light receiving units which receive light beams split by the one-dimensional metal grid.

Abstract: An optical pickup includes a polarization component separation element (43) which is formed as a unit or single piece of birefringence material. The separation element is not laminated, obviating the need to carefully match the optical axes of the laminated pieces. Multiple reflections within the birefringent crystal which comprises the separation element improve the separation and resolution of the polarized components which are extracted from a laser beam reflected back off the recording medium surface.

Abstract: A polarization optical element causes minimum loss and provides light in the visible and near-infrared regions with practically satisfactory polarization contrast even when the grid period is comparatively long. Metal grids (1) are formed on a substrate (2) with a refractive index n1 to satisfy conditions 0.2

Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable electronic apparatus without using a connector for electric connection between the front panel and the main body. SOLUTION: In an electronic apparatus where a front panel 3 including a display part and an operation part is coupled, capably of separation, with the main body 1, the electric coupling between the front panel 3 and the main body 1 is noncontact electric coupling (first and second coils 2a and 2b). Hereby, because this does not use a mechanical contact, this is not affected by dust or humidity at all, so the reliability increases.
