Inventor: TAKEUCHI RYOJI C O INTELLECTUA
IPC: G11B7/125
Filed: 1990-04-27
Abstract: In an information recording system, a semiconductor laser (13) is energized in response to a drive current which is modulated in accordance with a recording signal in a recording mode so that a modulated laser beam is generated from the semiconductor laser (13). The modu­lated laser beam is focused on an optical disk (1) and is reflected from the optical disk (1) and the reflected laser beam is detected by an photo-detector (12). A detection signal from the detector (12) is compared with a predetermined threshold level by a binary circuit (24) and a relationship between the recording signal and an output signal from the binary circuit (24) is detected by a detection circuit (30). In a overwrite mode in which the laser beam is focused on pit or pits on the optical disk (1), an overwrite detection signal is generated from the detection circuit (30) and the over­write detection signal is counted by a counter circuit (31). When the counter circuit counts a predetermined count value, the counter circuit (31) generates a recording inhibition signal for preventing the semicon­ductor laser from generating the modulated laser beam.

Abstract: It is provided a method and apparatus for writing a serial data pattern in the form of flux transitions on a magnetic medium. Data supply means (16) provide a serial data pattern, and delay circuitry (12) applies a pre-determined write delay value to the data pattern. The compensated data pattern is output to recording means (22) for writing the same on the magnetic medium. The delay circuitry is arranged to vary the pre-determined write delay value according to the particular data pattern, the writing head and the writing location whereby, when the data pattern is read back, the flux transitions are perceived to be at the same interval as were corres­ponding elements of the data pattern when they were introduced from the data supply means.

Abstract: The present invention relates to a timing logic implementing the synchronization of a portable telephone with a GSM network for maintaining the synchronization in all operating states of the telephone. The logic comprises a frame number counter (1), which is incremented by means of a frame interrupt derived from a frame length counter (2). In the frame length counter values are loaded from registers (3 or 4), which state whether the frame length is normal or deviating. From a neighbouring base stations' timing difference counter (6) the moment is obtained when reception of-synchronizing frame or BCCH data of neighbouring base stations is started. The difference of frame numbers and the frame timing bar timing difference between the own base station and the neighbouring base stations are stored in a neighbouring base stations' timing register (9), wherefrom the timing difference is loaded via a timing difference register (5) into the neighbouring base stations timing difference counter (6). A transmission advancing timing counter (7) gives the start pulse. The counter (7) receives the advancing value from the own base stations' timing registers (10), in which the transmission advancing value given by the own base station, and the value of the absolute reception time interval has been loaded.

Abstract: The invention relates to a hot water shut-off device provided for use with showers and the like for shutting off hot water when the hot water exceeds a predetermined temperature. 
     The device has a hot water inlet (54) and a cold water inlet (52). A temperature sensing expansion member (130) is provided to sense the temperature of the mixed hot and cold water so that if the temperature of the water exceeds a predetermined limit the expansion member expands to such an extent that it closes a valve (60) against a valve seat (71) to shut off supply of the hot water from the inlet (54). Cold water from the inlet (54) is continually supplied via a passage which bypasses the valve (60) and seat (71) so that cold water can be supplied to the temperature sensing, expansion member (130) to cool the member so that the device can reset quickly and allow hot water to pass through the valve (60) and mix with the cold water until the temperature of the water in the vicinity of the temperature sensing expansion member (130) exceeds the predetermined temperature.

Abstract: When data are thermo-magnetically recorded to a perpendicular magnetized film of a recording medium, it is possible to prevent unnecessary magnetic domains from being formed and unerasable magnetic domains from being produced. The medium 11 is rotated by a motor 12. When being passed through a recording field generated by a magnet 14, the medium 11 is irradiated with a recording beam generated by an optical head 13, so that data can be recorded to a perpendicular magnetized film of the medium 11 as bubble magnetic domains. Further, when the medium 11 passes through a correcting magnetic field generated by a magnet 15 disposed away from the position at which data are recorded, unnecessary and/or unerasable domains can be eliminated.

Abstract: Digital signals, such as digitized television signals, are subjected to a source coding step in which a class of "most important" data elements represents a proportionately greater amount of the information to be communicated than the rest of the data elements. This is followed by a constellation mapping step which is carried out in such a way that those data elements have a lower probability of being erroneously detected at the receiver than the others. The constellation mapping step uses coded modulation in order to provide enhanced noise immunity for the "most important" data element class.
