Abstract: An insulation system (10) is placed in ceilings or walls of buildings which are typically exposed on one side thereof to relatively large temperature changes and on the other side to relatively small temperature changes. The insulation system (10) includes a first thicker layer of insulative material (18) and a second thinner layer of insulative material (19), with an intermediate layer of phase change material (20) sandwiched therebetween. The phase change material undergoes a change of phase between solid state and liquid state during the course of a typical day due to the outside temperature ranging higher and lower than the phase change temperature.

Abstract: In a magneto-optic disk, a protective coating is applied to the magnetic recording layer made from a composite comprising minute particles of an inorganic compound, a lubricant and a radical-polymerizable resin. The surfaces of the minute particles of the first type are coated with a surface coating agent which has a lyophilic property with the radical-polymerized resin and this surface coating prevents the minute particles from forming aggregates in the protective coating.

The surfaces of the minute particles of the first type are coated with a surface coating agent, while those of the second type remain not coated. Thus, the minute particles of the first kind are not liable to form aggregates in the protective coating, whereas those of the other kind may form aggregates.
