摘要： In a digital recorded data reproduction which applies PRML signal processing, it is an object to enhance a reproduction signal quality and a playability for an abnormal signal by an offset correction and a phase-interpolation-type digital phase-locked loop. A prescribed frequency band of a reproduction signal is emphasized by a waveform equalizing unit 2, and its output signal is sampled by an asynchronous clock at an analog/digital converter 3. After a sampling signal is subjected to the offset correction, PR equalization is performed by a transversal filter 6 and a tap weighting factor control unit 8 which applies LMS algorithm, and a signal of a regular sampling phase is reproduced from its output signal by a high-order interpolation filter 7 employing a digital phase-locked loop 11. The reproduced signal in a regular phase is demodulated by a maximum likelihood decoder 12, thereby to reproduce digital data recorded on a medium.

摘要： A friction clutch includes drive and follow members. The drive member rotates together with the driving section and has a drive-side contact surface. The follow member rotates together with the end-bit mounting section and has a follow-side contact surface contactable with the drive-side contact surface. The friction clutch is movable between a transmission position where frictional force is produced between the drive-side and follow-side contact surfaces so that the output shaft and end-bit mounting section (5) can rotate together, and a cutoff position where the output shaft and end-bit mounting section are non-rotatable together. A shaft (42) has one end side rotatably supported by a first bearing (31A) and another end side rotatably supported by a second bearing (47A). The shaft supports the drive and follow members so that the drive and follow members are arranged coaxially in the axial direction. The drive and follow members are arranged between the first and second bearings.

摘要： A self-refreshing memory has a refresh timer that generates refresh requests at a certain rate, and a refresh address counter that generates refresh addresses by counting the refresh requests. A refresh test circuit receives test signals from automatic test equipment that cause it to disable the refresh timer, reset the refresh address counter, then enable the refresh timer for a certain interval. At the end of this interval the refresh test circuit disables the refresh timer again and generates an output signal such as a serial data signal indicating the current refresh address, or a pass-fail signal indicating whether the refresh address is equal to or greater than a preset pass value.
