Title: Production of aqueous chitosan solution and aqueous chitosan gel
Inventor: BAATOHORUTO NIISU
IPC: C08J3/03
Filed: 1994-10-27
Abstract: The invention relates to a process for the preparation of aqueous solutions and gels of chitosan in which chitosan and an acidic chelating agent are dissolved in water. Such solutions can be drastically increased in viscosity or converted into highly viscous gels by adding salts of polyvalent metals and acids in which chitosan is only moderately soluble or is insoluble. From such solutions, salt-like chitosan/chelating agent adducts can be obtained by removing water or by precipitation using an organic solvent.

Title: Hydrolysis of protein and preparation of seasoning utilizing the same
Inventor: HAYASHI RIKIMARU
IPC: A23L27/21
Filed: 1988-10-19
Abstract: PURPOSE:To shorten the hydrolysis reaction time in the preparation of a seasoning by hydrolyzing a protein with an acid or alkali under a pressure of as high as >=500 atm and neutralizing the hydrolyzed product. CONSTITUTION:An animal protein (e.g. protein of fish, shellfish, livestock, etc.) or a vegetable protein (e.g. soybean protein) is hydrolyzed with an acid or alkali and the hydrolyzed product is neutralized to obtain a seasoning. The acid used in the above hydrolysis is an inorganic acid (e.g. hydrochloric acid) or an organic acid (e.g. acetic acid or citric acid) and the alkali is e.g. sodium hydroxide. The other reaction conditions can be made milder than those of conventional hydrolysis process and the amount of the acid and alkali can be reduced by the hydrolysis under the above condition. The hydrolysis time can be shortened by this process.

Title: Ultrasonic transducer
Inventor: SATO YUKIO
IPC: A61B8/00
Filed: 1992-09-08
Abstract: PURPOSE:To obtain an ultrasonic transducer having high sensitivity and high resolution by setting the curvature of the convex face side of a vibrator so as to be made smaller than the curvature of the concave face side. CONSTITUTION:An ultrasonic transducer 10 has a cylindrical case 1 at the tip part of which a vibrator 2 is arranged. A matching layer 5 and a packing layer 6 are arranged on the radial face side and the back face side of the vibrator 2, respectively, and sound wave is converged by applying curvatures to the vibrator 2 and the matching layer 5. In this case, the radial face side becomes a concave face and the back face side becomes a convex face. At this point of time, the curvature of the concave face side of the vibrator 2 becomes 40mm and the curvature of the convex face side becomes 36mm, for instance, and the curvature of the convex face side is set so as to be smaller than the curvature of the concave face side at a range of 15% and less. Thus, when the ultrasonic transducer 10 is evaluated, a wider banding is performed and the lowering of the sensitivity can be suppressed.

Title: Fuel injection device
Inventor: SAKAGAMI EIJI
IPC: F02M67/12
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To eliminate the adhesion of fuel to the interior of a fuel injection device after measuring by forming longitudinally extended slits between a rod and the inner periphery of a fuel injection nozzle at a part where a rod insert- through hole is formed. SOLUTION: When a second coil 14 is excited by current application, a second movable core 34 is lifted against a coil spring 33, and a needle valve 35 is separated from a valve seat 37, so that fuel flows out to the first movable coil 22 side through a small hole 36. This fuel is led to a mixing chamber 26 through a communicating hole 24 and a communicating passage 25 of a rod 20 by compressed air fed from an air port 38. When a first coil 12 is excited in this state, an injection valve 21 is separated from a nozzle seat 18a through the rod 20 to inject fuel. In this case, slits 27a-27d are formed at the outer periphery of the rod 20 upstream of the mixing chamber 26 so as to prevent fuel from adhering to the outer side wall of the mixing chamber 26 by the flow of the compressed air.
