Abstract: The clutch cover assembly comprises a clutch cover, a pressure plate, a washer-type spring and a lever member. The clutch cover is fixed to a flywheel. The pressure plate is located within said clutch cover and is fashioned with a pressing surface for clamping facings against the flywheel. The washer-type spring engages the pressure plate to the flywheel. The lever member, supported by the clutch cover, is for engaging the pressure plate in combination with the washer-type spring to the flywheel and for releasing engaging loads of the washer-type spring from the pressure plate.

Abstract: A method of recording an optical disk, by irradiating a laser light onto a predetermined track of the optical disc to record information pits corresponding to an input composite signal including data signal and synchronization signal, includes the steps of: detecting a record timing of the synchronization signal to be recorded; and reducing at least one of a recording power and a recording duty of the laser light when the information pit corresponding to the synchronization signal is recorded by the laser light, according to the detected record timing.

Abstract: Disclosed is an information recording/reproducing apparatus using an optical recording medium, which can reproduce information from a recording medium designed to have a high linear recording density, by a method of performing signal separation/extraction by one threshold level in a level detecting process at the time of information reproduction from an optical recording medium with a high linear recording density.

Abstract: An apparatus for reproducing data from a recording medium on which data including phase adjustment pattern data are recorded, the phase adjustment pattern data including a plurality of solitary waves, the apparatus including: unit for reproducing the recorded data from the recording medium in synchronism with a read clock and producing a reproduced signal; unit for extracting the phase adjustment pattern data from the reproduced signal and producing the solitary wave signal; unit for detecting a phase shift between the reproduced signal and the read clock on the basis of the solitary wave signal; and unit for adjusting phases of the read clock and the reproduced signal to be in phase with each other on the basis of detected phase shift.

Abstract: A reservoir, provided with a device for warning when the level of an operation fluid to be supplied to a fluid pressure master cylinder drops below a given level, comprises a fluid tank for storage of the operation fluid and a float chamber with an upper wall provided on the side portion of the fluid tank. A reed switch for the fluid level drop warning device is provided at the lower portion of the float chamber, and a float having a magnet is retained in the float chamber. A partition for restricting the movement of the float is detachably mounted at the communicating section between the fluid tank and float chamber. This arrangement facilitates the mounting and replacement of the float and reed switch.

Abstract: A coal - water slurry at high concentration which has a low viscosity and favorable flowing property is prepared by using a surface active substance prepared by sulfonating and oxidizing at least one of the starting materials selected from distilled petroleum oils, petroleum pitches, asphalts, distilled coal oils, coal pitches or coals, applying condensation as required and then neutralizing the thus obtained product with alkalis.

Abstract: A cassette for accommodating a magnetic recording medium which includes a pressing member adjacent a head window pressing the recording/reproducing surface of a magnetic recording medium thereby flattening its surface. Spacing loss between the magnetic disc and the magnetic head and track deviation error are prevented thereby permitting precise recording and reproducing operations.
