Abstract: A seat device for a vehicle is provided in which a dynamic damper is formed of a weight and an elastic member supporting the weight so as to be capable of vibrating, and the elastic member is retained on a frame or a cushion member of a seat installed in the vehicle, wherein the weight is formed into a polyhedron whereas the elastic member is formed into a sheet shape, and the weight is covered and supported by the sheet-shaped elastic member. This enables the weight to be supported simply by the elastic member, and the dynamic damper to be provided at low cost.

A CPU 11 generates, at a pre-set time interval, an identification signal having a meaning at a pre-set time interval, and an identification signal addition circuit 3 adds the identification signal to the video signals and/or the audio signals. A sector forming circuit 5 and circuit components up to a recording/reproducing head 14 record the video signals and/or the audio signals and the ancillary identification signal on an optical disc 12.

Abstract: Users at a terminal are able to select network data using multiple, independently operated, cursors. These cursors include pointing devices, such as a mouse, a data tablet or other mechanism that selects data displayed on a terminal interface device. Decision logic may be used to determine which user has priority access when selected network content is desired by more than one user. This decision logic may be based on a user identity, terminal location, number of users at a terminal or other factors.

Abstract: A signal transmission method applicable to prevention of modification or alteration of the playback mode information, such as copying management information or charging information. The playback mode information form a terminal is data-converted for ciphering by a playback mode information appendage circuit in a header appendage circuit responsive to the key information from a terminal and the resulting information comprised of the data and the playback mode information is outputted. The reproducing side effects data conversion on the ciphered playback mode information for deciphering, by a playback mode information detection circuit in a header separation circuit, using the key information from a terminal, for taking out the original playback mode information at a terminal.

Abstract: A data transmitting method, a data recording apparatus, a data record medium and a data reproducing apparatus are provided to disallow the encryption to be easily decoded and keep the secrecy of key information higher. The data transmitting apparatus includes an error correction coding process block. In the block, an input converting circuit operates to perform a logic operation with respect to the information data from an interface circuit 12 according to the key data. The converted information data is sent to an encoder 15 for generating parity data. This parity data is mixed with information data before conversion in a mixing circuit. The error correction coding block operates to send the resulting data to a modulating circuit 17 for modulating the data. The modulated data is recorded on a disk record medium.

Abstract: An input is ciphered in at least one of a sector forming circuit 13, a scrambling circuit 14, a header appendage circuit 15, an error correction encoding circuit 16, a modulation circuit 17 and a synchronization appendage circuit 18, used for processing input data for forming a recording signal. Not only key for ciphering itself in the circuits but also the information as to which of the circuits has been used for ciphering becomes the key for ciphering. This realizes ciphering difficult to decode by a simplified structure.
