摘要： A wrist mechanism for attachment to the tip end of a robot arm has a first speed reducer for rotation about an ".alpha." axis that is coaxial with a ".gamma." axis of the robot arm. To the side of the robot arm is a second speed reducer for rotation about a ".beta." axis that is at a right angle with the ".gamma." axis of the robot arm. Bevel gears are respectively attached onto tip end of inner and outer rotation shafts of the robot arm. The bevel gear on the outer rotation shaft engages with an input bevel gear for ".beta." rotation on the ".beta." axis, thus transmitting wrist bending torque supplied from the robot arm. The bevel gear on the inner rotation shaft engages with a bevel gear on the ".beta." axis. The engaged bevel gear engages with a further bevel gear on one end of a shaft which is arranged at an acute angle with the ".beta." axis to rotate the shaft. On the other end of the rotated shaft a still further bevel gear engages with an input bevel gear on the first speed reducer for ".alpha." rotation, thus transmitting wrist rotation torque supplied from the robot arm.

摘要： Reproduction signals include patterns for which recognition errors are likely. With respect to such patterns, probable error patterns are prepared. Tables showing correct patterns and error patterns are prepared, and evaluation values accurately representing signal quality are calculated. In an apparatus using a PRML method, discrimination data and a plurality of predetermined bit sequence pairs are examined to detect matching. A bit sequence and corresponding two ideal responses are calculated. Euclidean distances between the two ideal responses and equalization signals are obtained, and the difference between the Euclidean distances is further obtained. A quality evaluation value of a reproduction signal is calculated based on a mean value, a standard deviation, an appearance probability of the predetermined bit sequence, and a Hamming distance between the predetermined bit sequence pairs.

摘要： The magneto-optical disk recording device disclosed is for recording and reproduction using a one-beam optical head and includes a magneto-optical head, a reproduction amplifier, a recording data delay circuit, a recording state detection circuit, a data comparator circuit, and a record judging circuit. The reproduction amplifier amplifies a magneto-optical reproduction signal read out by the magneto-optical head during the recording. The recording data delay circuit delays a recording data for a predetermined period of time. The recording state detection circuit receives the reproduction signal from the reproduction amplifier and detects a reproduced signal state during the recording. The data comparator circuit receives and compares an output of the recording data delay circuit and an output of the recording state detection circuit, and outputs a record failure signal. The record judging circuit judges whether to skip a record failure region or to verify a recorded state of the data when the record failure signal is outputted from the data comparator circuit. The arrangement enables the verification operation during the recording to be made simple thereby enhancing a recording speed.
