Title: Indirect solid phase antibody method
Inventor: IKEDA MASAYUKI
IPC: G01N33/543
Filed: 1990-05-02
Abstract: PURPOSE:To easily and exactly determine the antigen-antibody reaction in a soln. state by bringing a known quantity of antibodies and antigens into reaction in a soln., then diluting the soln. and determining the antibodies which doe not react with the antigens by the solid phase antibody method. CONSTITUTION:The ratio of the antibody quantity and the antigen quantity is set equal to or large than antibody valence. The antigens and the antibodies are brought into reaction in the soln.lcontg. ATP and DNA in the case of use of a soln. in which the factors to change antigenicity exist, for example, recA protein antigens. The reaction liquid is then diluted by a diluent, such as PBS, which does not dissociate the antigen-antibody conjugation to stop the antigen-antiboby reaction and to decrease the materials exclusive of the antibodies to the detection threshold of the solid phase antibody method or below. The antibody quantity in the diluted reaction liquid is measured by the various solid phase antibody methods, among which the enzyme antibody method is more preferable. The antibodies which do not react with the antigens are determined by this solid phase antibody method and, therefore, the antigen- antibody reaction is determined by subtracting this value from the antibody quantity before the antigen-antibody reaction.

Title: Joint for culvert
Inventor: ASANUMA YOSHINORI
IPC: E03F3/04
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To reduce the number of part items by providing a flexible sealing member of an S shape in cross section which is formed continuously with a swelling part which comprises a cylindrical flexible member and swells on the inner peripheral side and a swelling part which swells on the outer peripheral side, and installing each end part of the flexible sealing member to a mounting plate at different positions in the radial direction. SOLUTION: A flexible sealing member 9 is formed into an S-shape in cross section which is formed continuously with a swelling part 9a swelled on the inner peripheral side and a swelling part 9b swelled on the outer peripheral side. By this, when an internal water pressure is applied, an inner peripheral side swelling part 9a is reversed and the flexible sealing member 9 swells to the outer peripheral side as a whole and, to the contrary, when an external water pressure is applied, an outer peripheral side swelling part 9b is reversed and the flexible sealing member 9 swells to the inner peripheral side as a whole. Therefore, even when any of the inner and outer pressures is applied to the flexible sealing member 9, it can distribute it uniformly.  Thus, because only one flexible sealing member is used and no withstanding member is used, a joint has such advantages that the number of part items is small, production cost is low, weight is low, and handling is easy.

Title: Removal of dissolved oxygen using hydrogen activated in plasmatic state
Inventor: KAWASAKI HIRONOBU
IPC: C02F1/58
Filed: 1995-04-05
Abstract: PURPOSE: To prevent foods from being qualitatively degraded and piping from being corroded by removal of dissolved oxygen by introducing hydrogen gas into a plasma generation device to activate the hydrogen gas in the form of plasma, then blowing this activated hydrogen into an aqueous solution, and causing it to chemically react with hydrogen dissolved in the aqueous solution. CONSTITUTION: Hydrogen gas originating from a hydrogen gas storage device 2 is introduced into a plasma generation device 1 and is activated in the form of plasma. Next, this plasmatic activated hydrogen gas is blown into an aqueous solution 3 from a gas blower 4. Consequently, the dissolved oxygen in the aqueous solution 3 is removed as water by a chemical reaction with the plasmatic hydrogen gas. Thus, it is possible to prevent oxidation and qualitative change by dissolved oxygen from occurring and at the same time, to remove active oxygen such as ozone or hydrogen peroxide. If this method is applied to an aqueous solution such as beer, fruit/vegetable juices, tea or milk, it can be preserved freshly for a long time. In addition, if the method is applied to tap water, a harmless active oxygen-free water can be prepared.  Further, the method is beneficial to the production of a circulating water which inhibits the corrosion of a metal part exposed to a boiler steam.

Title: Method for gloss processing of planographic printed matter
Inventor: OSHIMA KUNIYOSHI
IPC: B41M7/00
Filed: 1990-05-08
Abstract: PURPOSE:To obtain a clear film excellent in gloss, the adhesiveness to a cellophane sticking tape and secondary processing properties such as bending properties, sizing aptitude or abrasion resistance by adding an alkyd resin to an ultraviolet curable resin composition. CONSTITUTION:The use amount of the alkyd resin in an ultraviolet curable resin composition is usually 2 - 50wt.%, pref., 5 - 40wt.%. When the use amount of the alkyd resin exceeds 50wt.%, ultraviolet curing properties markedly become inferior and no pref. effect is obtained because there is a tendency to cause strike-through at the time of printing. When the use amount of the alkyd resin is below 2wt.%, a tendency to become difficult in the balance control of gloss, the adhesiveness to a substrate and secondary processing properties is generated when the substrate is oily ink. The ultraviolet curable resin composition may contain a radial polymerizable monomer and a photopolymerization initiator other than the alkyd resin and may further contain a radical polymerizable oligomer if necessary.
