Title: Hydrous gel base agent
Inventor: IWAMA YOSHINORI
IPC: C08B37/00
Filed: 1995-04-21
Abstract: PURPOSE: To obtain a stable hydrous gel base agent hard to generate collapse in shape even in a weak acidic region by adding locust bean gum to glucomannan to adapt the same to the water retention and cold reservation of an object. CONSTITUTION: A hydrous gel base agent contains glucomannan and locust bean gum as effective components. At this time, locust bean gum functions as a water separation preventing agent and makes the collapse in shape of glucomannan hard to generate even in a weak acidic region to stably keep glucomannan. When the content of locust bean gum is below about 0.1wt.%, the keeping of shape retention is hardly developed and, when the content of locust bean gum exceeds about 5.0wt.%, the hydrous gel base agent becomes too hard and does not become a gel state. The hydrous gel base agent may contain glucomannan and carrageenan. The content of carrageenan and the property of an addition product are the same as those of locust bean gum.

Abstract: PURPOSE:To simplify measuring operations, by alternative and speedy switching into high and low stages of a gauge voltage supplied to a bridge circuit and from its corresponding strain wave forms, induced noise is practically removed by sampling provided by shifting time between concave and convex parts. CONSTITUTION:When a pulse 101a caused from a clock pulse generating circuit 101 is supplied to a voltage switching circuit 102, high-gauge voltage VH and low-gauge voltage VL are supplied alternatingly to a bridge circuit 103, causing thus an output wave of the circuit 103 to assume a shape of 104a. On the other hand, an output of an output switching command circuit 105 is read out, a delay is given by a point adjusting circuit 106 by the specified length of time, sampling of each point voltage value on the wave 104 a is performed with 108 in an alternated manner and the pulse 101a is held during a period of one cycle. A subtracting calculation (110) of the output value is performed by giving an input of thus held wave shape into a microtime holding circuit 109 and by amplifying-smoothing (111, 112) of the wave shape, induction noise is removed virtually and a required strain wave shape can be obtained. Thus, significant simplification of measuring operations becomes available.
