Title:
CONTINUOUS MEASUREMENT OF CONCENTRATION OF SUBSTRATE IN FLUID
Document Type and Number:
Japanese Patent JPS622150
Kind Code:
A
Abstract:

PURPOSE: To miniaturize a passage pattern while facilitating the manufacture, by arranging a sensor at a bend of a curved passage combining two planar members each with the inner surface made convex and concave skewly by making the two abut against each other.

CONSTITUTION: Two Si single crystal substrate sheets are made with one thereof as passage upper die 1 an the other as passage lower die 2 and the worked surfaces thereof are bonded as opposed to form a curved passage. When a fluid of the passage runs toward the upper die passage 4' from the lower die passage 3', the passage is bent so that is contacts the top surface of the upper die passage at more than 50° and a window is opened at the wall part which the fluid contacts as being bent and a glucose sensor 6 is fixed from the back. This enables the miniaturization of the passage pattern while facilitating the manufacture.
