Abstract: A laminated optical component, including a transparent substrate, a transparent adhesive layer superposed on the transparent substrate, the transparent adhesive layer including both a first type of crosslinking and a second type of crosslinking of (meta)acrylic polymer, the first type of crosslinking being formed of a first reaction site selected from a first group consisting of: a hydroxyl group, a carboxyl group, and an amino group, and a second reaction site selected from a second group consisting of: an isocyanate group, an epoxy group, and a metal atom, and the second type of crosslinking being formed by addition polymerization of unsaturated double bond, and a transparent film superposed on the transparent adhesive layer, wherein the transparent substrate, the transparent adhesive layer, and the transparent film form a flush-ended laminate having an end surface.

Abstract: A method for producing an at least partially transparent optical component including a laminate including fabricating a precursor laminate by bonding a transparent substrate and a transparent film to each other with a transparent photocurable adhesive layer interposed therebetween; curing the transparent photocurable adhesive layer by applying light thereto to change the precursor laminate into the laminate thereby, such that a shear modulus G? of the transparent photocurable adhesive layer of the laminate measured under a condition of a temperature of 25° C. and a frequency of 1 Hz reaches a value within a range of 3×105 Pa?G??3×107 Pa; and forming a flush and surface of the laminate by cutting the laminate in a thickness direction, such that the flush end surface includes respective cut surfaces of the transparent film, the transparent photocurable adhesive layer, and the transparent substrate.

Abstract: An electrophoretic medium best suited as a separation medium is composed of a gel solution and contains a water-soluble polymer and permits great improvement of the enzymic protein recovery character. A gel holder is provided with stopper members and thus can hold even a soft or slippery while maintaining a fixed shape thereof, thus permitting reliable separation and purification of an intended substance without possibility of denaturing of the substance. A slab type electrophoretic apparatus permits automatic detection of the electrophoretic state of a sample and automatic completion of the electrophoresis under optimum conditions without setting measurement condition, permits continuous measurement of the buffer solution temperature, which is important for obtaining an electrophoretic condition for maintaining the enzymic function, and permits separation and purification of a large quantity of an enzyme or like physiologically active substance in a very simple operation.
