Title: Signal amplification of immunoassay by adjustment of enzyme catalytic action
Inventor: PATORITSUKU DEII MAIZU
IPC: C07F9/12
Filed: 1987-11-19
Abstract: A method for enzyme immunoassay for a ligand suspected to be present in a liquid sample includes signal amplification by use of at least two enzymes and a blocked modulator for one of the enzymes. Ligand present in the liquid binds to an antiligand and an enzyme-labeled tracer. The resulting bound fraction is separated and the enzyme in the tracer removes the blocking group from the blocked modulator. The modulator activates or inhibits a second enzyme which catalyzes the conversion of a substrate to a product. The presence or absence of the ligand in the liquid is indicated by a signal, such as a color change or a rate of color change, associated with the product. The invention includes a new class of enzyme inhibitors and blocked inhibitors and a kit of materials useful for performing the method of the invention.

Abstract: PURPOSE:To avoid the collision between a cable crane bucket and a cart and to stop the cart with the shortest safety distance from the bucket, by using a computer to calculate accurately the distance from a start point. CONSTITUTION:A cart 1 is driven automatically between a batcher plant 31 and a point S.

While the cart 1 receives the deceleration signal from the computer at an instant when it passes through a set deceleration start point alpha and starts its deceleration. Then the cart 1 stops by sensing the stop signal sent from the computer at an instant when the cart 1 reaches the point beta. The cart 1 detects the arrival of a bucket 32 hanged down from a cable crane and then starts again at a low speed to approach slowly to the bucket 32. Then the cart 1 stops at an instant when it touches the bucket 32 and discharges the concrete.
