A disc reproduction apparatus capable of stabilizing the position of the circumferential edge of a disc during the disc loading and preventing the disc from abutting on a turntable. In the disc reproduction apparatus of the type that a disc (10) squeezed between a disc guide (5) and a disc roller (4) is loaded while the roller (4) is rotated, a disc contact surface of the disc guide (5) is slanted so that the disc is spaced from a turntable (2) along a disc transport direction when the disc is loaded.

When starting to receive a multiplex PSK signal of BPSK, QPSK and 8PSK signals, a selector (16A) of a demodulator (1A) reads three most significant bits DELTA phi (3) of phase error data corresponding to I and Q symbol streams from a phase error table (15-1) for BPSK among those classified according to modulation type and phase angle. A phase angle detector (8A) detects phase angles, corresponding to bits (1) and (0) of the frame sync signal in the received symbol stream, from DELTA phi (3) and the MSB of the I symbol stream, and supplies them to a remapper (7) to generate absolute phases. A selector (16A) retrieves phase error data, corresponding to the received symbol stream, from a phase error table associated with the type of modulation and the phase angle identified by a transmission mode detector (9). The retrieved data are sent to a digital-to-analog converter (17) to correct the phase of the reference carrier for quadrature demodulation so that received signal point may have a fixed phase with respect to the transmission signal point.

A multiplication value decision unit (12) decides a multiplication value which is a positive value or a negative value corresponding to a bit value of each bit contained in a binary bit string constituting a scramble pattern generated in a pattern generation unit (11). A multiplication processing unit (13) multiplies symbol data representing each symbol value in the symbol data string formed by the multinary symbol containing a predetermined pair of a positive value and a negative value having an identical absolute value, in the value area, by the multiplication value decided by the multiplication value decision unit (12). Here, the multiplication processing unit (13) successively executes the multiplication between the symbol data for one symbol and the multiplication value decided corresponding to the bit value of the one bit contained in the scramble pattern until the number of symbols expressed by the symbol data string is reached. The present invention scrambles the data string by a simple operation and performs scramble by a simple processing even when the function channel content is changed.

When a sound presence/absence detector (12) detects a sound absence interval, a non-modulated carrier signal is outputted in an area used to transmit speech data that are included in transmission data having a frame structure and that correspond to the sound absence interval. That is, an FSK modulator (14) causes a transmitting circuit (15) to output the non-modulated carrier signal from a wireless communication apparatus (100) in the area used to transmit the speech data corresponding to the sound absence interval. In the meantime, a four-level FSK modulated wave signal is outputted in the areas other than the one of the sound absence interval. A non-modulation discriminating data for allowing the sound absence interval to be determined are included in an area of channel identifying information included in the transmission data having the frame structure, and allow a communication terminal apparatus at the receiving end to avoid any unstable operations. The present invention is suitable for narrowed bands of communication paths and reduces the affections on adjacent channels.

A disk clamp mechanism of a disk device which, during the rotation of a disk, securely prevents a contact from occuring between a clamper holding part (10) and a clamper (8) and a contact between the clamper holding part (10) and the disk and clamps or unclamps the disk by moving a clamper holding chassis (1) which holds the clamper (8) through the clamper holding part (10) toward or away from a turn table, wherein a lever is supported on the clamper holding chassis (1) rotatably around a shaft (9a) and rotated interlockingly with the movement of the clamper chassis (1), and a clamper contact part (10a) of the clamper holding part (10) is displaced in the moving direction of the clamper holding chassis (1) relative to the clamper holding chassis (1) and in the radial direction of the clamper (8) by the movement of the lever relative to the clamper holding chassis (1).
摘要:
There is provided a service class control system and the like for facilitating modification of a service class of a terminal device or disabling unauthorized modification of the service class. A service class management server (1) contains service class data for specifying a range of service provided by the user terminals 2-1 to 2-n. When a user terminal 2-k transmits data requiring a start of providing a service, in response to this, service class data indicating the service class of the user terminal 2-k is transmitted to the user terminal 2-k. After receiving the service class data, the user terminal 2-k provides a service of the range specified by the service class data.
