Title: Magneto-optical disk
Inventor: YAMADA TAKASHI
IPC: G11B11/105
Filed: 1987-08-28
Abstract: PURPOSE:To prevent the hygroscopic expansion of a substrate while maintaining good recording sensitivity by forming a protective layer of a specific film thickness consisting of the acid nitride of silicon on the surface of a resin substrate on the side opposite to the surface formed with a recording layer. CONSTITUTION:The protective layer which consists of the acid nitride of the silicone and satisfies the equation d>=100 and d<=1,000-2,000 deg..(n1-n0) (where n1>n0, d is the layer thickness of the protective layer; n1 is the refractive index of the acid nitride of the silicon; n0 is the refractive index of the resin substrate) is formed on the surface of the resin substrate on the side opposite to the surface formed with the recording layer. The dense protective layer consisting of the silicon acid nitride having >=100Angstrom thickness is thus formed. The thickness of the protective layer is limited to the range of 1,000-2,000(n1-n0) (where n1>n0) or below and is set to about the extent at which the light absorption by the protective layer is increased and the recording density is not affected. The good recording density is thereby maintained and the hygroscopic expansion of the substrate is prevented.

Title: Preparation of thermal recording material
Inventor: HIBINO TAKESHI
IPC: B41M5/28
Filed: 1990-08-16
Abstract: PURPOSE:To hold high recording density without losing the surface smoothness of a protective layer by heat-treating the roll of a thermal material whose protective layer is set to a specific value or more in smoothness tightly wound so as to bring the degree of repulsion thereof to a specific value or more at specific temp. for a predetermined time. CONSTITUTION:In a thermal recording material wherein a thermal color forming layer containing a basic dye and a developer is provided on a support and a protective layer containing a water-soluble polymer and a crosslinking agent is provided thereon, the Bekk smoothness of the protective layer is set to 300 sec or more and the roll of the thermal recording material tightly wound so that the degree of repulsion due to a Schmidt paper roll test hammer becomes 15 or more is treated at 30-50 deg.C for 24hr or more. When the degree of repulsion is 15 or less, the surface smoothness of the protective layer is lowered with the acceleration of crosslinking reaction by heat treatment and color forming sensitivity is damaged. When treatment temp. is lower than 30 deg.C, the crosslinking reaction of the water-soluble polymer and the crosslinking agent is insufficient and water resistance is deteriorated and, when the treatment temp. is higher than 50 deg.C, the thermal color forming layer develops a color to lower whiteness. When the treatment time is shorter than 24hr, crosslinking reaction becomes insufficient.

Filed: 1988-08-30
Abstract: PURPOSE:To attain a long range transmission without being affected from noise by generating a spread spectrum wave corresponding to a level '0' or '1' and taking the correlation between the spread spectrum wave and a reference wave. CONSTITUTION:Spread spectrum waves, e.g., chirp waves C1, C2 are selected and assigned to levels '0' or '1' of transmission signals respectively and the chirp waves C1, C2 are sent according to the transmission signals.

In this case, the noise component in the received wave is almost a '0' level by taking the correlation and the signal component is emphasized because it is equivalent to autocorrelation. Thus, the long distance communication is attained without being affected by noise and without incorporating any battery.
