Abstract: Provided is a sample collection and separation device comprising a sample collection unit having a sample collection portion that uses capillary action and an analyte storage unit having a housing into which the sample collection unit is inserted, whereby the sample collection unit containing the collected sample is integrated by means of insertion, so as to permit centrifugation and storage or transport of the sample, and the target sample can be recovered following centrifugation.

Abstract: An exemplary blood sampling tool/device can be provided with which, even when a small amount of sample is collected, such amount of sample can be collected in a state suitable for a later analysis. The exemplary blood sampling tool/device can comprise, e.g., a pipette tip-shaped blood sampler having openings at an upper part and a lower part having an interior space for aspirating and retaining blood by the capillary action. This exemplary tool/device can also comprise a blood container having a hydrophilically treated inner wall and bottom, and having a protrusion provided at the bottom that is able to accommodate the blood collected by the blood sampler. A sealing lid can also be provided for sealing the blood container.

Abstract: The purpose of the present invention is to provide a sealing device which has forward and reverse screw threads exhibiting a fluid-pumping action provided on a sliding portion of a seal lip, such that the pumping action is less susceptible to deterioration even with increasing wear on the screw threads and such that leakage of droplets from the screw threads is minimized. To achieve this, the forward and reverse screw threads which exhibit a pumping action on sealing fluid are arranged in a circle on the air-side lateral surface of the sliding portion of the seal lip. The forward and reverse screw threads each have a shape gradually increasing in thread height from the leading end of the lip to the air side. The forward screw threads and/or reverse screw threads are provided with seal protrusions for preventing leakage of droplets.

Abstract: A purpose of the present invention is to provide a device which enables to collect a very small amount of a sample in a state suitable for later examination, without using an absorbent or a chemical solution, even when a very small amount of a sample is collected. A further purpose is to provide a device which enables to collect blood suitable for later blood examination, even when the sample is a very small amount of peripheral blood instead of brachial vein blood. Yet a further purpose is to provide a very small sample collection and separation device for use in measuring a very small amount of peripheral blood sample with good accuracy using a conventional reagent and analytical apparatus.

Abstract: The invention provides a sealing device which can inhibit an external dust in an atmospheric side from intruding into a lip end, thereby inhibiting a sealing fluid leakage by trapped dust. In a sealing device inhibiting leakage of a sealing fluid in an inboard side to an atmospheric side, coming into contact with a shaft by a seal lip end and circumferentially having in an atmospheric side inclined surface of the seal lip with a plurality of screws exerting a pumping action to the sealing fluid, a three-dimensional shape for preventing the dust intrusion is provided between the screws so as to inhibit the external dust intrusion in the atmospheric side toward the lip end. The three-dimensional shape is constructed by a projection or a groove extending in a parallel direction to the lip end. The projection or the groove is connected to the screws longitudinally in both end portions.

Abstract: In an engine rear seal installed to an engine rear portion having an end plate arranged in a motor exterior side of a housing, and a flywheel arranged in a motor exterior side of the end plate, the engine rear seal has an oil seal and a muddy water preventing seal. The muddy water preventing seal integrally has an attaching portion, and a seal lip directed to a diametrically outer side from the attaching portion and slidably coming into close contact with an end surface in the motor exterior side of the end plate. The seal lip has an inclined lip end back surface portion, and is structured such that a lip end comes into contact with the end surface at the low-speed rotating time and the lip end moves away from the end plate on the basis of an action of a centrifugal force at the high-speed rotating time.
