Abstract: A connector holding device includes a body-side connector attached to an apparatus body; a cord-side connector for fitting with the body-side connector, provided on the front end of a cord drawn out opposite to the side fitting with the body-side connector; and a connector holding member for holding the cord-side connector, having an opening formed with its cord side smaller than its side fitting with the body-side connector. The device attaches the connector holding member to the apparatus body in a state where the cord-side connector fits with the body-side connector.

Abstract: An optical disc device and a disc changer drive capable of achieving a reduction in cost and number of articles and a reduction in size of the disc drive with a simple configuration rather than the prior art and also carrying out a stable playing/writing operation are provided. An optical disc device includes a playing chassis which is supported turnably on a main body of the disc drive and on which a turntable is installed, a substantially Y-shaped cam groove formed on the playing chassis, a driving lever on which a substantially T-shaped cam groove is formed and which transmits a power to a holding portion of the disc, and a turning lever supported turnably on the main body and engaged with the playing chassis and the cam groove of the driving lever via a driving shaft, wherein a turning of the turning lever is followed by a turning of the playing chassis and a movement of the driving lever that follows the turning of the playing chassis to hold a disc as a series of operations.

Abstract: Radio communication apparatus comprising an antenna, a transmitting circuit of outputting a transmitting signal in a first frequency band. A duplexer connected to the antenna and having a single-phase input terminal and a balanced output terminal, conveying the transmitting signal inputted to the single-phase input terminal to the antenna. The duplexer outputs a receiving signal in a second frequency band different from the first frequency band received from the antenna substantially as a differential signal from the balanced output terminal. A receiving circuit connected to the balanced output terminal and having a circuit in which a gain of a signal of a differential component is higher than that of a signal of an in-phase component, or a loss of the signal of the differential component is lower than that of the signal of the in-phase component.

Abstract: A subcutaneous fat thickness measuring apparatus includes: a light source section that irradiates a surface of a living body with plural light rays having different central wavelengths; a light receiving section that receives the plural light rays of different wavelengths emerging from the surface of a living body and determining the quantities of the plural light rays received; and a calculator section that calculates the thickness of subcutaneous fat of the surface of a living body from the quantities of the plural light rays received measured by the light receiving section using a previously determined relationship among subcutaneous fat thicknesses, blood concentrations in subcutaneous fat and quantities of plural light rays having different central wavelengths.

Abstract: A radio communication method for transmitting data to radio stations, wherein propagation parameters to be estimated in a receiving station are controlled, based on the data transmitting, by an array antenna comprising a plurality of antenna elements to perform data transmitting in a transmitting station. This allows channels characterized by the propagation parameters to be shared only by particular radio stations, and signals are superimposed on the propagation parameters, thereby realizing radio access in which a high security is retained.

Abstract: An impulse radio communication device includes a wave detector for generating a detected signal, a switching section for selecting either a received signal or the detected signal in accordance with an external control signal and outputting it as a demodulation target signal, a reference waveform generating section synchronized with the demodulation target signal and generating a reference waveform signal having a different waveform in accordance with the external control signal, a demodulator for generating a demodulated signal from the demodulation target signal in accordance with the reference waveform signal, and a decoding section for decoding received data from the demodulated signal. This impulse radio communication device switches the demodulation target signal and the reference waveform signal simultaneously in accordance with a receiving and synchronizing state.

Abstract: An optical disk device which includes a pickup module; a control board for processing the electrical signal received by a pickup from an optical disk and controlling sliding of the pickup; and a flexible cable for coupling the pickup and the control board. The pickup module includes the pickup for reading information on a recording face of the optical disk; a spindle motor for retaining and rotating the optical disk; and a frame on which the spindle motor is disposed. The control board is fixed to a chassis, and the pickup module is fixed to the chassis only via elastic bodies. The cable is disposed to be surrounded by the chassis and the pickup module.

Abstract: A dispersion-type EL device includes a short-bar contact, a first insulating layer, a back electrode layer, a dielectric layer, a luminescent layer, and an optically transparent electrode layer, which are sequentially formed on a temporary substrate that has been processed with an exfoliation treatment. This configuration realizes a reduction in size in a thickness direction. Furthermore, an illuminated switch unit is provided, in which a dispersion-type EL device peeled off from a temporary substrate and a wiring board having a comb-like contact are connected to each other.

Abstract: A mobile communication apparatus includes a registration request part (47) requesting a correspondent node to make location registration, a BU list memory (45) keeping a list of the correspondent nodes which have made the location registration, a handover detection part (41) detecting the start of a handover, and a registration cancellation processing part (46) canceling the location registration of the correspondent nodes in the BU list, upon notification of start of handover by the handover detection part (41), thereby reducing loss of packets transmitted from the correspondent nodes during the handover, because the route optimization applied to the correspondent nodes registered in the BU list at the start of the handover is canceled by requesting the cancellation to the correspondent nodes.
