摘要： In a marine gas cylinder apparatus provided with a switching valve apparatus capable of switching a communication state among a piston rod side oil chamber, a piston side oil chamber and a gas chamber, the switching valve apparatus is structured such that each of respective poppet valves are arranged in each of ports open to a communication chamber provided in a valve case, each of balls is held between a ball operation surface of a rotation plate supported to the valve case and each of the poppet valves. Each of the poppet valves is moved close to or apart from the corresponding port via each of the balls in accordance with a rotating operation of the rotation plate.

摘要： The disk drive, which is used for performing at least a reproducing operation for a disk-shaped recording medium having a PEP region where information relating to the at least a reproducing operation is recorded, includes: a rotator for rotating the recording medium; a pickup for reading a signal from the recording medium; processing circuits for thresholding a length of a period in which the level of the signal remains unchanged; a demodulating circuit for receiving the thresholding result and for demodulating the signal to reproduce the information based on the thresholding result; a detector for detecting the rotation speed of the recording medium and for outputting a rotation speed signal indicative of it; correcting circuits for receiving the rotation speed signal, and for supplying a discrimination value in accordance with the rotation speed of the recording medium. The discrimination value is used for thresholding the length of the period. In the disk drive of the present invention, the signals are demodulated based on the thresholding result obtained using the discrimination value, whereby allowing the information to be reproduced correctly while the rotation speed of the recording medium changes.
