Abstract: A testing method for testing a liquid flowmeter, the method including introducing a test liquid and a sealant having a specific gravity smaller than that of the test liquid into a weighing tank until an outlet of a pipe is submerged in the test liquid; causing the test liquid to pass through the pipe; acquiring readings of a weighing scale configured to measure a weight of the weighing tank at multiple time points, and time information representing the time points; acquiring readings of the liquid flowmeter; calculating a standard flow rate of the test liquid based on the readings of the weighing scale at the multiple time points and the time information; and calculating an instrumental error between a measured flow rate based on the readings of the liquid flowmeter and the standard flow rate.

Abstract: A swab testing device comprises a container (1) containing a diluent (7), a cap (10, 20) detachably mounted on an opening of the container, an elongating stick (4) secured to or integral with the cap, and a cotton swab (5) connected to a leading end of the stick and immersed in the diluent when the container opening is closed with the cap. The cap provides a communicating channel (12, 14, 27, 31) communicatable with the interior (6) of the container and also communicatable with the atmosphere by an aperture (23a) formed on the cap. The cap also includes a lid (15, 25) by which the aperture may be opened and closed. Any liquid in the container may be discharged through the communicating channel and the aperture, when the lid is opened to communicate the channel with the atmosphere through the aperture, even when the container opening remains closed with the cap.

Abstract: An injection molding apparatus includes a vessel, mold, pusher, and thrust providing section. The vessel stores a molding material and has a nozzle hole which is formed in the bottom portion to inject the molding material and a first seal surface formed around the nozzle hole. The mold is made up of stacked members stacked on the lower side of the vessel and is filled with the molding material injected from the vessel. The mold has a sprue communicating with the nozzle hole and a second seal surface formed around the sprue. The stacked members respectively have third seal surfaces at portions where the members are in contact with each other. The pusher pressurizes the molding material in the vessel. The thrust providing section provides a thrust to the pusher to pressurize one of the pusher and the mold through the molding material in the vessel.

Abstract: A filter bag (1) comprises a first thin plastic film (22); a second thin plastic film (21) having substantially the same size with the first plastic film and sealed to the first plastic film at a first side-peripheral edge (2a), a second side-peripheral edge (2b) opposite to the first side-peripheral edge and a bottom peripheral edge (2d) thereof to provide an open-top interior, and a filter sheet (5) having a length substantially equal to the first and second plastic films and a width smaller than the first and second plastic films. The filter sheet has a first longitudinal edge (5a) interposed and sealed together between the first side-peripheral edges of the first and second plastic films and a second longitudinal edge (5b), opposite to the first longitudinal edge, sealed to the inside of the first plastic film at an intermediate position in width of the filter bag.
