To provide a blood treatment filter device capable of efficiently utilizing a blood treatment filter. A blood treatment filter devicehas a filter sheetthrough which a specific component among components forming blood is harder to pass than other components and a spacer sheetthrough which the specific component is easier to pass than through the filter sheet. The filter sheethas filter through-holesdisposed at intervals. The filter sheetand the spacer sheetare spirally wound in an overlapped state. The filter devicehas sealssealing both end portions in the longitudinal direction of a wound bodyformed by the filter sheetand the spacer sheetwhich are spirally wound in a fluid-tight manner. The outer peripheral surface of the wound bodyis formed by the filter sheet

A medical tube clamp wherein first and second plate parts including, on opposing surfaces, compressive protrusions for closing a medical tube are provided with a pair of side walls on both sides projecting from one toward an other of the plate parts, and are also provided with a central guide protrusion projecting from the other toward the one of the plate parts. Both sides of a tip portion of the central guide protrusion make sloping guide surfaces projecting toward a center. When the plate parts are displaced relative to each other so as to become closer, lateral displacement of them is corrected by a slide of the pair of side walls and the sloping guide surfaces, and the central guide protrusion is inserted between the pair of side walls.

A defocus amount of an object is detected by a focus detection unit of a camera, whereby a defocus velocity is calculated according to the detected amount. An average velocity is calculated using a plurality of defocus velocities and then a smoothing velocity is calculated, whereby a reversed position of a velocity direction is detected using the data. An average velocity, a smoothing velocity, and the time of a velocity direction reversed are calculated, whereby a correction velocity is obtained according to the calculation. A driving amount of lens is calculated according to the calculated correction velocity, whereby the photographic lens is driven by the lens driving device so as to follow the moving of an object.

Automatic focusing device

An automatic focus adjusting apparatus of a camera calculates amount of defocus of an object, and repeatedly calculates the speed of the image plane of the object based on the amount of defocus. When releasing operation of the camera is started, image plane speed of the object at the time of exposure is estimated by using a secondary curve based on the speed of the image plane, and the lens is driven based on the data thereof. Since the image plane speed of the object is estimated by using the secondary curve equation, correction of the amount of defocus can be accurately done regardless of the speed of movement of the object.
