Abstract: An automated demolding apparatus for reliably and repeatedly mechanically separating contact lens mold portions of a mold assembly without damaging the contact lens formed therebetween. The mold assembly includes a first front mold portion having a central mold section with a surrounding flange, and a corresponding second back mold portion also having a central mold section with a surrounding flange. A molded contact lens is formed between the front and back mold portions, and the flanges of the front and back mold portions are spaced apart and parallel to each other. The demolding apparatus includes restraining fingers positioned between and on opposite sides of the spaced flanges of the first and second mold portions and against the flange of the first mold portion. A separating fixture includes separating fingers positioned between and on opposite sides of the spaced flanges of the first and second mold portions and against the flange of the second mold portion. Before demolding, the second mold portion is irradiated by a laser beam, which is absorbed thereby to cause a substantial temperature gradient between the second mold portion and the contact lens being demolded. The temperature gradient causes a differential expansion and shifting of the surface of the heated second mold portion relative to the surface of the lens to lessen the adhesion therebetween to assist in separation of the mold portions, while leaving the lens in the first mold portion. During demolding, the separating fixture is rotated relative to the restraining fingers to progressively separate and peel the second mold portion from the first mold portion.

Abstract: The present invention discloses a biologically active basement membrane composition. When polymerized under physiological conditions, the composition forms gel-like structures whose ultrastructure resembles interconnected thin sheets of the lamina densa zone of basement membrane. The major components of the composition include laminin, type IV collagen, heparan sulfate proteoglycan, entactin and nidogen. These components polymerize in constant proportions when redissolved and allowed to reconstitute. Molecular sieve studies on the soluble extract demonstrate that laminin, entactin and nidogen are associated in a large but dissociable complex. The reconstituted matrix is biologically active and stimulates the growth and differentiation of a variety of cells, including epithelial cells, nerve cells, hair follicles and the like. The reconstituted matrix can also be used for determining metastatic potential of tumor cells and for isolating metastatic tumor cells.

Abstract: PURPOSE:To fix chip parts to a substrate in a highly precise manner by a method wherein the attached position of a chip part is corrected utilizing the balance of the spring force of the two elastic wires bonded between the chip part and the substrate. CONSTITUTION:A bonding agent 2 is painted on the prescribed place of a substrate 1, and a chip part 3 is fixed thereon temporarily. Then, two elastic wires 41 and 42 such as ribbon-like bonding wires and the like, for example, are bonded between the substrate and the chip part 3. At this time, the bonding position of the elastic wires 41 and 42 is set in the direction wherein the deviation (x) of the mounted position of the chip part is corrected. In the state wherein the bonding of the elastic wires 41 and 42 is finished, the unbalance of elastic force corresponding to the above-mentioned (x) is generated, but after a short time, the chip part 3 moves until the elastic force of the elastic wires 41 and 42 is brought into equilibrium as shown by the arrow (c) in the diagram. Then, the mounted position (b) of the chip part 3 is brought in coincidence with the true mounted position (a) with a very small error.
