Abstract: PURPOSE:To obtain a food additive consisting of phytoproteins of high nutritive value, proteins containing essential amino acids such as lysine in good balance, and virtually free from allergen proteins. CONSTITUTION:5-10 pts.wt. of an organic solvent (e.g. hexane) is added to i pt.wt. of buckwheat seed flour followed by agitation, and the resultant precipitate is gathered through filtration and air-dried to obtain defatted buckwheat seed flour, which is, in turn, subjected to extraction using an aqueous solution of an inorganic salt at concentrations of 0.5-3wt.% (e.g. an aqueous solution of sodium chloride) to obtain an aqueous solution containing both globulin and albumin components. From this aqueous solution, the globulin component alone is precipitated by such isoelectric point precipitation method that this aqueous solution is adjusted to 3.8-5 in the pH value at 0-20 deg.C, and separated through e.g. filtration and then dried at reduced pressures, thus affording the aimed food addituve.

IPC: G11B7/26
Filed: 1990-11-20
Abstract: PURPOSE:To achieve a long life and improve reliability by a method wherein, after SiO2 system sol is applied to the reading surface of a glass plate, a protective film is formed by baking. CONSTITUTION:Ultraviolet-curing resin 2 is applied lightly and uniformly to a stamper 1 and a glass plate 3 on which an SiO2 thin film which is a protective film is formed is made to adhere closely to the resin 2. At that time, the surface of the glass plate 3 on which the Si02 thin film is not formed is made to adhere closely to the ultraviolet-curing resin 2. After an ultraviolet radiation is applied through the glass plate 3 to cure the resin 2, the resin sticking to the optical disc plate is peeled off from the stamper 1. Thus, an optical disc substrate is manufactured and a recording layer 4 is formed on the resin to which the uneven pattern of the optical disc substrate is transcribed to manufacture an optical disc. With this constitution, a long life and highly reliability optical disc substrate can be obtained.

Title: Horizontally confronting type flying press
Inventor: MASUDA BUNPEI
IPC: B21B1/02
Filed: 1989-12-05
Abstract: PURPOSE:To prevent a slab from the generation of the abnormal deformation of buckling or torsion, etc., and roller marks by performing edging forming by clamping the slab from the direction of thickness with press rolls which are arranged in the vicinity of dies and of which full length is larger than the width dimension of slab. CONSTITUTION:In a horizontally confronting type flying press with a pair of dies 6, 6 which are confronted each other on both sides of the transfer line S of slab and which are made to be approachable and separable in the width direction of slab, the slab 1 is clamped from the direction of thickness with the upper and lower press rolls 5a, 5b which are arranged on the upstream side and in the vicinity of a pair of the dies 6, 6. Therefore, in the case that the slab 1 is edging formed, buckling or torsion isn't generated on the slab 1 and transfer to the ensuing stage isn't gotten into difficulty due to the abnormal deformation of the slab 1. And, since the full length of the upper and lower press rolls 5a, 5b are made larger than the width dimension of the slab 1, the quality of products can be improved without generating roller marks on the surface or the rear of the slab 1 when edging forming.

IPC: C23C14/20
Filed: 1990-11-22
Abstract: PURPOSE:To easily obtain a conductive-surface polymeric film having excellent conductivity and transparency by converting the metal layer formed on the polymeric film surface into a sulfide layer. CONSTITUTION:A metal is deposited on the surface of a polymeric film to form a thin-film layer excellent in adhesion, which is then treated with gaseous hydrogen sulfide. Consequently, the metal is converted into its sulfide without the adhesion and homogeneity being damaged, and a polymeric film having excellent transparency and surface conductivity is obtained. Since the thickness of the deposited metal is freely controlled by this method, the resistance of the sulfide thin film layer is freely changed, and a conductive-surface polymeric film having desired performance is obtained.
