Patent JP-H01117781-A (JP)
Title: Chemically modified enzyme
Inventor: HAYASHI RYUZO
IPC: C12N9/04
Filed: 1987-10-31
Abstract: PURPOSE:To enable oxidation-reduction reaction even in a system having low dissolved oxygen concentration, by using an oxidase requiring flavin adenine dinucleotide as a coenzyme and bonding the oxidase with benzoquinones through covalent bond. CONSTITUTION:An oxidase requiring flavin adenine dinucleotide as a coenzyme (e.g., glucose oxidase) is dissolved in a buffer solution having a pH of about 8-9 (e.g., sodium phosphate buffer solution). Benzoquinones (e.g., p-benzoquinone or naphthoquinone) dissolved in a solvent (e.g., methanol) are added to the above solution and thoroughly mixed and reacted to bond the benzoquinones to the oxidase through covalent bond. Since the obtained chemically modified oxidase catalyzes oxidation-reduction reaction even in a system having low dissolved oxygen concentration, it can be suitably used as an analytic reagent for clinical diagnosis, a biosensor or a bioreactor.

Title: Color three-dimensional display device
Inventor: RONARUDO ESU GOORUDO
IPC: G02B30/25
Filed: 1991-09-30
Abstract: PURPOSE: To typically generate a full-color image by combining a delay device, a prism, a secondary coating, and a polarizing coating and allowing lights of colors having long and middle wavelengths to pass through an optical film but reflecting light of colors having short wavelengths by an optical film. CONSTITUTION: A beam 22 passes a side 19 of a prism 13 and is made incident on a quarter-wave delay device 30, and incident linearly polarized light is converted into a circularly polarized light. It is reflected from a dichroic layer 32, the direction of its circular polarization is inverted, and the beam 22 turns into a beam 26. The dichroic layer 32 allows red light and green light to pass through, and the beam 26 is made incident on an optical coating layer 20 from the delay device 30 through the side 19. It is reflected as a blue beam 28 by the coating layer 20 and is linearly polarized. A beam 34 consisting of red light and green light is converted into a circularly polarized light by a quarter- wave delay device 36, and the dichroic layer 32 allows red light and green light to pass through but reflects blue light.  This transmitted light becomes a linearly polarized light beam 40 and is reflected by the coating layer 20. Thus, blue is a component for right eye and red and green are three-dimensional components for left eye, and a full-color image is obtained.

Abstract: PROBLEM TO BE SOLVED: To surely and safely pull up a single crystal having a large diameter and a heavy weight in a chamber under reduced pressure while preventing the single crystal from falling. SOLUTION: A seed crystal 24a is immersed in an Si melt in a quartz crucible 14 and pulled up to form a neck part 1a of small diameter under the seed crystal 24a.

Abstract: PROBLEM TO BE SOLVED: To shorten whole tapping process time in a machine tool. SOLUTION: In a tapping method for a machine tool, a tap starts to be rotated while it is fed fast in the axial direction of tapping and is rotated at predetermined rotational speed. A fast feed speed is decreased and, when the feed speed reaches the feed speed which is synchronous with the predetermined rotational speed in a relation consistent with the lead of a screw, a tapping operation is started at the predetermined rotational speed and, in the middle of tapping operation, the rotational speed and the feed speed are synchronously decreased in a relation consistent with the lead of a screw and the tapping operation is completed.  A reverse rotational speed and a return speed are synchronously increased in a relation consistent with the lead of a screw to perform a return process and, after the reverse rotational speed reaches the predetermined rotational speed, the return process is continued while both speeds are kept.
