摘要:
Nonlinear, optical thin-films comprising a plurality of island structures of semiconductor ultra-fine particles and a plurality of continuous films of an optically transparent material, said island structures and said continuous films being applied alternately on a substrate. A method for manufacturing nonlinear, optical thin-films comprising the steps of: (a) providing a substrate; (b) depositing an island structure of semiconductor ultra-fine particles on the substrate or a continuous film; and (c) depositing the continuous film of optically transparent substance on the island structure; (d) the steps (b) and (c) of depositing an island structure and the continuous film being performed alternately.

摘要:
A polymer composition containing a physiologically active substance which can be released at a controlled rate is prepared by contacting one or more polymerizable monomers with the physiologically active substance, making the monomers into a specific shape and then irradiating the shaped article with light or an ionizing radiation at a low temperature below room temperature to polymerize the polymerizable monomers.
摘要:
In an electronic timepiece equipped with both an analog display section having time indicating hands and a digital display section, a time correction system is provided whereby correction of both the analog and digital time displays can be performed by rotation of a crown, with the directions of rotation of the crown for time data incrementation and decrementation being identical both for analog and digital display correction. Selection of either analog time correction or digital time correction is performed simply by pulling the crown out to either of two axial positions. Correction of both analog and digital time display information is thereby simplified and made more rapid, while the number of external operating members is reduced.
摘要:
A polymer composition containing a physiologically active substance and being capable of releasing it at a controlled rate can be prepared by contacting 10 parts, by weight, of one or more polymerizable monomers and 0.1 to 30 parts, by weight, of one or more physiologically active substances and irradiating them with light or an ionizing radiation while maintaining the system in an anhydrous condition and in airless state.
摘要:
Enzymes and/or bacteria cells are immobilized by forming an aqueous mixture of enzymes and/or bacteria cells and a hydrophobic, vitrifiable monomer in an amount of at least 76% by weight of all monomers present, and irradiating the mixture by means of ionizing radiation at a temperature less than -10.degree. C. to polymerize the monomer.
摘要:
Enzymes are adsorbed on an adsorbent powder in an aqueous medium and a water-miscible monomer is added thereto, and said monomer is polymerized to form a porous gel lump through which a substrate solution can freely pass. The thus formed enzyme composition has long-lasting activity and thus the enzymes can be easily separated from the reaction system and can be used repeatedly.
摘要:
A process for producing a composition containing insolubilized enzyme and/or insolubilized bacterial cells which comprises (i) the step of mixing (a) an aqueous solution of enzyme and/or an aqueous dispersion of bacterial cells, (b) at least one porous adsorbent and (c) at least one vitrifiable monomer.
摘要:
Trioxane can advantageously be polymerized in the presence of a thiocyanate (an ester of thiocyanic acid), to obtain an oxymethylene polymer having thermal stability. The polymerization is further promoted by means of an ionizing radiation or an ultraviolet light.
