Title: Immobilization of substance having enzymatic activity
Inventor: HIJIKATA KENJI
IPC: C12N11/04
Filed: 1981-04-08
Abstract: PURPOSE: To prepare immobilized enzyme having high enzymatic activity and stable for a long period, by using a specific blocked isocyanate compound hardenable with water at normal temperature, as the gel substrate.  
     CONSTITUTION: A urethane prepolymer obtained by the reaction of a polyisocyanate with a hydrophilic polyol prepolymer having a molecular weight of 1,000W20,000 is made to react with an isocyanate blocking agent selected from a heterocyclic compound having the skeleton of formula in the molecule, e.g. imidazole, sym-triazole, etc., hydroxypyridine, hydroxyquinoline, and substituted phenol having a pKa of 5W9.5. The equivalent ratio of the OH group and/or the NH group of the blocking agent to the NCO group of the urethane prepolymer is 0.2W2. The cold-curing blocked isocyanate compound thus obtained is mixed with a substance having enzymatic activity, and the aqueous mixture is gelatinized to obtain the immobilized enzyme.

Title: Sensitive press activating device and its operation
Inventor: TAKAHASHI IWASHIGE
IPC: F16P3/14
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To carry out a formed article and to carry in the materials simultaneously with the bottom dead center of a slide by invalidating the emergency stop through the shielding of the optical axis of an optical type safety device when the slide is in the rising stroke, on the basis of the detection signal of a crank angle sensor, and accepting the break of light shielding and passing for automatic actuation. SOLUTION: When actuated from the top dead center with an operating button, the slide 4 descends, performs machining, and moves to the rising stroke. The acceptance of the break starts concurrently with the passing of the slide near the bottom dead center, when an operator's hands enter the working area, shielding the light of an optical type safety device 7 and taking out a finished product; and, upon the detection of the recovery of the light transmission through the optical curtain, a first break is accepted. When the light is again shielded of the optical type safety device 7, with a material set on the lower die 3 and with the hand withdrawn, a second break is accepted upon the detection of the recovery of the light transmission through the optical curtain.  The slide 4 is stopped at the top dead center and also checked; if normal, it is operated for the next one stroke; and if abnormal, it is left stopped at the top dead center.

Inventor: AMITANI KOJI
IPC: H04N5/32
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To enhance the S/N of an X-ray image signal. SOLUTION: The X-ray image pickup panel 12 onto which an X-ray transmitted through an object such as a human body is projected is provided with 1st and 2nd X-ray image pickup sections 13, 13' respectively having photoconductive layers 62, 62'.

Title: Creep preventer for car fitted with automatic transmission
Inventor: NISHIKAWA MASAO
IPC: F16H61/04
Filed: 1983-03-28
Abstract: PURPOSE:To apply an engine brake with certainty even in case should trouble happen, by selecting a starting fluid passage carrying a throttle from or to an engine brake fluid passage paralleled in a way of interlocking with select motion of a manual select device, while interconnecting them to a working fluid passage selectively. CONSTITUTION:In the case where a creep preventing valve Vc is left opened intact, when an engine brake is applied, a manual valve Vm is shifted to an engine brake position, namely, a first speed holding position I whereby a starting fluid passage 111 is intercepted from a working fluid passage 41a, and an engine brake fluid passage 126 being interconnected to a hydraulic pump P is interconnected to the hydraulic fluid passage 41a. Therefore, high pump discharge pressure is directly led into the working fluid passage 41a in consequence, so that such engaging pressure as being required for engaging a low-speed step clutch C1 is led into a hydraulic cylinder 40a. Accordingly, a low-speed step gear train G1 is set up on a firm basis and thereby the engine brake can be applied, though the creep preventing valve Vc is left opened intact.

Abstract: PURPOSE:To obtain a digital display type balance by composing a capacitor of metallic flat plates hung vertically through an arm lever stuck to the longitudinal lever of a Roberval's parallel motion mechanism, and a metallic flat plate fixedly stood at the corresponding position. CONSTITUTION:Through an arm lever 17 stuck at an adequate position of the longitudinal lever 3 of a Roberval's parallel motion mechanism B, a hung lever 14 to which a couple of metallic flat plates 13 are stuck at the lower end is hung vertically. A metallic flat plate 18 is stood upright on a base A'' at small  intervals and in parallel at a corresponding position where the metallic flat  plates 13 are hung, and the metallic flat plates 13 and 18 constitute a parallal  flat plate capacitor 8A. When a body 6 is placed on a dish 5, the Roberval's  parallel motion mechaism 7 operates to lower the hung lever 14 vertically, and  consequently the counter area between the metallic flat plates 13 and 18 of the  capacitor 8a varies.

Title: Overhead projector
Inventor: KAJIYAMA KOUSUKE
IPC: G03B21/132
Filed: 1983-03-29
Abstract: PURPOSE:To utilize light effectively and hold the illuminance on a screen the same or more even with less electric power by using a secondary curved surface reflecting mirror and an annular prism and allowing light emitted from a light source in a circumferential direction to contribute to projection. CONSTITUTION:Light emitted forward from the light source 11 is made incident to the center part 16a of a Fresnel lens 16 through a condenser 13 and light emitted backward is reflected by a spherical reflecting mirror 12 and incident to the Fresnel lens 16 through the condenser 13 as well as the light emitted forward. Further, light emitted from the light source 11 in a circumferential direction is reflected by an approximately parabolic reflecting mirror 14 and refracted by the annular prism 15 to enter the circumferential part 16b of the Fresnel lens 16. Thus, the light in the circumferential direction which does not contribute to projection conventionally at all contributes to the projection and this light has a large value almost a half as large as that of the whole luminous flux emitted from the light source 11, so a projection image on the screen 19 is 1.5-2 times as bright as before.

Title: Cap opener for cap of small diameter
Inventor: TAKAHASHI SHIGEYA
IPC: B67B7/15
Filed: 1995-02-06
Abstract: PURPOSE: To enable a light wrenching force to cut open a cap of small diameter easily and safely in contradistinction to the fact that people often have trouble cutting open such a cap on a PET bottle, bottle of tonic, or the like by wrenching. CONSTITUTION: A cap opener consists of a cap-caulking part 1 and a grip 2 in one piece. In gripping a cap, the grip 2 is turned while a finger is pressed against a finger hold 3 at the tip of the caulking part 1, causing tension to act on the caulking part 1; then the frictional force and elasticity of the material in use work to increase the wrenching force of the caulking part 1. By turning the grip 2 further the moment of rotation is amplified. Thus a cap of small diameter, hence being one of small moment of rotation, can be cut open easily by wrenching it lightly.
