Inventor: ORUKAWA MASAHIRO
IPC: G11B11/10
Filed: 1994-07-21
Abstract: PURPOSE:To provide a magneto-optical recording medium reducing an edge shift by performing proper recording compensation ranging to the whole surface of a disk related to a recording method in magnetic field modulation recording. CONSTITUTION:This method is a recording system using a magneto-optical disk rotating at a constant angular velocity and switching a high power light pulse and a low power pulse according to a polarity of magnetic field for the magnetic field modulated positively/negatively. At this time, the delay amount deltat of the high power pulse is reduced according to going from the inner periphery of the disk to the outer periphery, or a power ratio between the low power pulse and the high power pulse is changed according to a recording diameter. Thus, the edge shift is reduced while securing a large overwrite power margin ranging to the whole recording area of the magneto-optical disk.

Abstract: PURPOSE:To tightly maintain a closed state of a cover for many years by providing a seat at the center of the lower part of a body, providing a caul in contact with the seat at the lower part of the cover, and providing a clamping screw for clamping the caul at the seat at the cover. CONSTITUTION:A seat 81 is provided at the center of the lower part of a body, and a caul 94 is provided at a position corresponding to the seat 81 at the lower part of a cover 2. Further, a clamping screw 101 is clamped to a fix a closed state of the cover 2. In this case, even if the screw 101 is tightly clamped, its clamping force is operated only to clamp the caul 94 to the seat 81. That is, since a caul surface 95 is already brought into contact with a supporting surface 84, a force to be applied from a clamping surface 104 by clamping to a pressure receiving surface 96 is operated only to press the surface 95 to the surface 84. Accordingly, since forces for deflecting the body and the cover do not act on them, waterproofness due to coalescing of peripheral edges of the body and the cover is effectively effected.

IPC: C23C16/00
Filed: 1992-06-29
Abstract: PURPOSE:To obtain a hard thin film of an organosilicon compd. excellent in transparency, corrosion resistance and environment shielding property by subjecting hexamethyldisiloxane or vinylmethoxysilane as a gaseous monomer to plasma polymn. at a specified oscillation frequency under a specified pressure of the gas. CONSTITUTION:At least one of hexamethyldisiloxane and vinylmethoxysilane is used as a gaseous monomer and subjected to plasma polymn. at 1-20kHz oscillation frequency under <=2X10<-1>Torr pressure of the gas to form a thin film. By this method, a colorless thin film requiring no succeeding process and having no wettability is obtd. in a clean environment. The reason why the monomer is used is that it has high vapor pressure, is easily introduced into a reactor and usually gives a hard thin film. When the oscillation frequency is below the lower limit, satisfactory plasma polymn. is not carried out. When it exceeds the upper limit, the formed thin film is damaged. When the pressure of the gas exceeds the above-mentioned value, a thin film is not obtd. and fine powder is formed.
