20150107348 | METHOD AND APPARATUS FOR INSPECTING A FLUIDIC DEVICE - A curing degree of a bonding layer is checked when a hollow microchannel is produced by bonding a plurality of plates through intermediation of the bonding layer. Provided is a method of inspecting a fluidic device including: one substrate and another substrate, at least one of the substrates having a minute groove formed therein; and a hollow channel formed by bonding the substrates to each other through intermediation of an adhesive layer having a contact angle that changes depending on a curing degree by irradiation of light. The method includes measuring a flow rate at which a solution flows through the channel with a capillary force when no liquid is present after the irradiation of light. | 04-23-2015 |
20150314287 | FLOW CHANNEL DEVICE, METHOD FOR MANUFACTURING FLOW CHANNEL DEVICE, AND METHOD FOR INSPECTING FLOW CHANNEL DEVICE - A device and a method for reducing man-hours for the inspection of a bonding in a flow channel device including a hollow flow channel disposed therein by bonding a plurality of substrates together. A flow channel device includes a plurality of hollow flow channels established by bonding substrates together in an overlapping manner, with at least one of the substrates including a plurality of grooves on a surface of the substrate, wherein a depressed shape at which bonding quality can be determined is provided at a position different from positions of the flow channels on at least one of the surfaces of the bonded substrates. | 11-05-2015 |
20150346079 | TESTING DEVICE AND METHODS FOR TESTING TAPE SEAL STRENGTH - A testing device for testing adhesion seal strength of a tape to a substrate. The testing device includes a body defining a chamber having a first port in fluid communication with the chamber, a platform sealingly attached to the chamber and having an elongate opening or a plurality of openings therethrough as a second port of the chamber. The testing device further includes a frame removably mounted to the platform. The frame defines a perimeter that surrounds the second port and, when mounted to the platform, secures a test substrate thereunder against the platform with a fluid-tight seal. Methods for preparing a test sample and methods of operating the testing device are also disclosed. | 12-03-2015 |
20160018315 | NON-DESTRUCTIVE ADHESION TESTING OF COATING TO ENGINE CYLINDER BORE - Adhesion testing of coatings to the cylinder bore of an engine block. An adhesion testing fluid is dispensed from a nozzle that simultaneously rotates so that the fluid impinges about a substantial inner periphery defined by the coated cylinder bore. The performance of a referee coated engine block is used to provide parameters for one or more production-oriented engine blocks. This allows for rapid evaluation of a sizable sample of such production-oriented engine blocks. The fluid-dispensing nozzle is configured to simultaneously provide complete circumferential coverage of the cylinder bore with high-pressure/high-velocity fluid through rotational movement of the nozzle within the bore. By keeping the production-oriented engine blocks stationary during the test further improves testing efficiency. | 01-21-2016 |
20160047736 | CROSS-CUT TESTER - A cross-cut tester includes a handle with a receiving cavity, and a plurality of blades received in the receiving cavity. One end of the handle defines an opening. The cross-cut tester further includes a plurality of gaskets received in the receiving cavity. The gaskets and the blades are positioned one-by-one, and are detachably fixed in the receiving cavity. The cross-cut tester of the present disclosure can effectively improve the efficiency of drawing lines and reduce the cost. | 02-18-2016 |
