Abstract: A biochemical detection device is revealed. The biochemical detection device includes a cap and a base arranged at two ends of a test tube correspondingly and a driving member disposed on the base. A sample-mounting slot and a test-paper-mounting slot separated from each other are formed in the test tube. After sampling, a sample obtained is placed into the sample-mounting slot and mixed with an extraction solution therein. A thin-film on the sample-mounting slot is penetrated by the driving member to allow the extraction solution mixed with the sample flowing into a cavity of the test tube to react with a test strip in the test-paper-mounting slot. The test cost is reduced and the detection efficiency is improved due to simple structure and easy operation. Moreover, the sample and the extraction solution are sealed in the test tube to prevent environmental pollution caused by spread of viruses.

Abstract: A continual manufacturing process includes steps of preparing a combined band consisting of two-layers of material sheets and plural swab sticks having their heads sandwiched orderly between the two layers of material sheets, a step of placing the combined sheet together with the sticks and moved on the table by a conveying roller to pass between a roller-type knife mold and a supersonic vibrating head to let the roller-type knife mold press a part of the two layers at the head of each stick, and a step of cutting the part of the material sheets at the head of each stick by means of punch knives of the roller-type knife mold and of being heated by the roller-type knife mold to soften and to be adhered to the head of each stick to make finished swabs.

Abstract: A method and system for retrieving images using a coupled knowledge-base/database is provided, the method comprising the steps of modeling structural knowledge by identifying classes and attributes of classes, determining relationships among the classes, operations for each classes; modeling heuristic and general procedural knowledge by acquiring heuristic rules for each class dependent on the application domain, specifying data processing procedures required by the heuristic rules acquired; modeling control knowledge by specifying intra-class-hierarchy searching paths, specifying intra-class-hierarchy searching paths, and representing the specified search paths in triggers for each class; and deriving a schema for the coupled database from the structural knowledge.
