摘要： Data synchronization detection is provided between data identification and code demodulation in a data reproduction system, which performs data synchronization detection using code-modulated data. A specified bit pattern generated in a data codeword is calculated in each phase (bit), using a specified bit sequence pattern that is not generated in a specified phase of the data codeword. For example, a specified bit sequence pattern is generated only in a specified phase of the codeword). The positions of the data codeword partitions are thereby identified. Scrambling is then applied to the write data as required in order to ensure accurate synchronization detection.

摘要： A video signal recording/reproducing device has at least a frequency modulating unit which FM modulates information to be recorded on an optical disk memory, a laser driving pulse generating unit for generating a laser driving pulse derived from the frequency-modulated signal generated by the frequency modulating unit and for modifying the duty factor of the laser driving pulse in accordance with the linear velocity of the optical disk memory where recording is taking place; and a recording unit for controlling the laser power during recording to an optimum value in accordance with the linear velocity of the optical disk memory where recording is taking place. This arrangement enables reduction of the minimal length of recording bits resulting in reproduced signals of a level sufficient for obtaining reproduced images of a fine quality addition enables increase of the recording capacity of the optical disk memory.

摘要： A gas is introduced into a discharge chamber of an ion source apparatus, and a gas discharge is performed between a thermionic cathode and an anode. Ions are extracted from the plasma formed in this gas discharge by a grid electrode. The thermionic cathode has a hollow cylindrical shape. A cathode chamber is defined by the thermionic cathode and a cylindrical partition wall supporting it. A columnar auxiliary electrode is coaxially inserted in the thermionic cathode. An A.C. voltage from a power source unit is supplied between the thermionic cathode and the auxiliary electrode such that effective power for keeping the thermionic cathode at a positive potential with respect to the auxiliary electrode is higher than that for keeping the auxiliary electrode at a positive potential with respect to the thermionic cathode.
