Title: Flowmeter
Inventor: KAMEGAWA MASAYUKI
IPC: G01F1/68
Filed: 1987-06-22
Abstract: PURPOSE:To measure a flow rate accurately by determining the flow rate in a tubular body from a difference in an oscillation frequency between two oscillators using two capacitors in the tubular body as circuit elements respectively. CONSTITUTION:A heat of a heating body 3 is transferred to a fluid flowing through tubular body 1, and thereby a temperature difference is caused between capacitors 2a and 2b provided on the upstream and downstream sides respectively. Owing to the capacitive temperature characteristics of the capacitors 2a and 2b, a difference occurs in an oscillation frequency between oscillators 4a and 4b in accordance with said temperature difference. Since the temperature difference between the capacitors 2a and 2b is dependent on the flow rate of the fluid, the difference in the oscillation frequency between the oscillators 4a and 4b correlates with the flow rate of the fluid flowing through the tubular body 1, and thus a flow rate detection signal of a digital output can be obtained.

Title: Immobilized enzyme and its preparation
Inventor: KAWASAKI TAKASHI
IPC: C12N11/08
Filed: 1982-09-06
Abstract: PURPOSE:To prepare an immobilized enzyme capable of keeping the enzymatic activity for a long period, by immobilizing an enzyme to a water-dispersible polymer by physical adsorption, and reacting a polyamine with a dialdehyde in an aqueous dispersion of the particle of the polymer. CONSTITUTION:Enzyme is immobilized to a water-dispersible polymer particle by physical adsorption, and a polyamine is made to react with a dialdehyde in the aqueous dispersion of the polymer particles to deposit a polymer consisting of the Schiff's base of the polyamine and the dialdehyde on the surface of the polymer particle. The average particle diameter of the water-dispersible polymer is 0.03-2mu, preferably 0.07-1mu. When the particle is too small, the recovery of the immobilized enzyme supported on the particle from the aqueous dispersion after the enzymatic reaction becomes difficult, and when it is too large, the surface area of the particle per unit volume becomes small resulting in the reduction of the amount of the immobilized enzyme and the poor dispersibility of the particle in water.
