Title: Anisotropic conductive film detector
Inventor: TAKAKUWA SHOICHI
IPC: G01M11/00
Filed: 1995-03-27
Abstract: PURPOSE: To surely detect the anisotropic conductive films on comb-shaped electrodes by using a photoelectric sensor of a reflection type. CONSTITUTION: The comb-shaped electrodes 5 are formed by forming a metallic film on a base 6 and etching this metallic film to a comb shape. The photoelectric sensor 41 of the reflection type projects sensor light S1 from the pitch direction of the comb-shaped electrodes 5 and a diagonal direction. The sensor light S1 is reflected by the respective electrode side surfaces of the etched comb-shaped electrodes 5 when there are no anisotropic conductive films 7. This reflected light is photodetected by the photoelectric sensor 41. The sensor light S1 is reflected in the direction opposite to the photoelectric sensor 41 on the surfaces of the anisotropic conductive films 7 when there are the anisotropic conductive films 7. The reflected sensor light is not photodetected by the photoelectric sensor 41.  The presence or absence of the anisotropic conductive films 7 is detected according to whether the photoelectric sensor 41 photodetects the reflected light or not.

Abstract: PROBLEM TO BE SOLVED: To easily and precisely measure an insoluble inorganic powder quantity on the surface of a fertilizer by bringing the fertilizer having the insoluble inorganic power on the surface into contact with a solvent, filtering the solvent to collect the insoluble inorganic powder on a filter element, and measuring the filter cake quantity. SOLUTION: A solvent (alcohol such as methanol, ethanol or the like; ketone such as acetone or the like) is added to a fertilizer having an inorganic powder (diatomaceous earth, talc, kaolin or the like) insoluble to water or organic solvents on the surface, shaken by use of a solvent extracting shaker to bring the solvent into contact with the fertilizer, and the insoluble inorganic powder is separated from the fertilizer surface into the solvent. This solvent is filtered by a filter element such as filter paper or membrane filter, and the insoluble inorganic powder is collected on the filter element as filter cake.  The quantity of the collected insoluble inorganic powder is determined by subtracting the preliminarily measured weight of the filter element from the weight of the filter element and filter cake after drying, or determined from the residual quantity by putting the filter element and the filter cake in a crucible, and perfectly burning and incinerating the filter element at a high temperature.
