摘要:
A silicone emulsion composition is disclosed which comprises specific amounts of (A) a colloidal silica-silicone core/shell material comprising (a) from 80 to 5 wt % colloidal-silica cores and (b) from 20 to 95 wt % shells comprising a specific polyorganosiloxane containing ethylenically unsaturated groups, (B) a specific polyorganohydrogensiloxane, (C) a curing catalyst, (D) an emulsifying agent, and (E) water. Also disclosed is a process for producing a silicone powder which comprises bringing the silicone emulsion composition into contact with a liquid or a gas while heating the composition at a temperature of 25.degree. C. or a higher and keeping the same in a dispersed state to thereby cure the silicone in the form of a powder. The silicone emulsion composition can give an elastomer having excellent mechanical properties upon the removal of the volatile components by heating. The particulate silicone obtained by the process from the emulsion composition has excellent mechanical strength, a small particle diameter, good uniformity in shape, and excellent dispersibility.

An absorbent member and a method for making such an absorbent member. The absorbent member includes a modified water absorbent resin having good production efficiency, absorbency against pressure, absorption speed, gel strength, and liquid permeability. The modified water absorbent resin may be made by mixing a water absorbent resin, water, and a water-soluble radical polymerization initiator without addition of an ethylenically unsaturated monomer to obtain a water absorbent resin composition, and irradiating the water absorbent resin composition with active energy rays. During irradiation, the surface water content of the water absorbent resin is at least 3.0 wt %.
摘要:
A packing package includes a gusseted container formed from laminated films and having opposite side walls and gussets extending between the opposite side walls, and a spout attached to an opening in the gusseted container. The laminated film forming either the two opposite side walls or the gussets is provided with a heat insulating barrier. The laminated film forming the gussets is not provided with any heat insulating barrier when the two opposite side walls are formed from the laminated film provided with a heat insulating barrier. The laminated film forming the two opposite side walls is not provided with any heat insulating barrier when the gussets are formed from the laminated film provided with a heat insulating barrier.

The present invention provides a pseudorandom number generating system, an encryption system, and a decryption system. The pseudorandom number generating system of the present invention repeatedly performs simple transformation of a non-secure pseudorandom number sequence that may be generated quickly, and thus may quickly generate a highly secure pseudorandom number sequence having a long period. In addition, the encryption system and the decryption system of the present invention do not generate a large encryption function difficult to be deciphered based on a shared key 122, but prepare multiple functions 126, which perform fast, different types of transformation, and select a combination of functions determined based on information of the shared key 122, and make the selected functions transform a text multiple times, thereby encrypt the text. Each of the functions is basically fast, and thus transformation by the entire combination is also fast. Furthermore, since the combination of functions and repetitive count for them can be changed, future improvement in specification is easy. Moreover, security is high since which functions are applied in what order is unknown.
