Abstract: The stent has an expansive force 0.05 N/mm or less per unit length when it has a diameter equal to the lower limit diameter of the target blood vessel and is measured under the following conditions. A radial force testing system manufactured by Blockwise Engineering LLC is used as a tester. The test conditions include a temperature of 37° C.±2° C. in the chamber of the tester; a stent diameter of 0.5 mm for start of test, and a rate of increase of diameter of 0.5 mm/s in the tester. The test method includes radially compressing the stent disposed in the chamber; recording an expansive force while gradually increasing the diameter of the chamber at the rate of increase of diameter; and dividing the expansive force by the effective length of the stent to calculate an expansive force per unit length.

Abstract: A feeding device includes a loading portion, a lifting mechanism, a conveying unit, a sheet detector, a near-end detector, and process circuitry. The loading portion stacks a plurality of sheets. The lifting mechanism lifts the loading portion. The conveying unit conveys the sheets on the loading portion. The sheet detector detects presence or absence of the sheets on the loading portion at a specified height position. The sheet count detector detects a number of sheets conveyed by the conveying unit. The near-end detector detects a near-end state in which a stack height of the sheets on the loading portion is a specified value or less. The process circuitry controls the lifting mechanism based on a detection result of the sheet detector before the near-end state is detected, and controls the lifting mechanism based on a detection result of the sheet count detector after the near-end state is detected.

Abstract: A self-expandable stent has sufficient radial force, has good bending properties, and recovers the shape for the diameter thereof to return from a diameter in a contracted state to a diameter before contraction around a body temperature (37° C.). The self-expandable stent includes a crosslinked polymer containing a constitutional unit (A) obtained from a monomer that constitutes a rigid biodegradable polymer when homopolymerized and a constitutional unit (B) obtained from a crosslinking agent, in which a content of the constitutional unit (B) is 15% by weight to 35% by weight with respect to a content of the constitutional unit (A).

Abstract: A sheet-material supply device includes a lift, a sheet-material detector, and a sheet-material retaining conveyor. The lift elevates sheet materials in a stacked state. The sheet-material detector detects that an uppermost sheet material of the sheet materials in the stacked state has reached a predetermined height. The sheet-material retaining conveyor retains and conveys the uppermost sheet material that has reached the predetermined height. The sheet-material supply device stops elevation of the sheet materials in the stacked state when the sheet-material detector detects that the uppermost sheet material has reached the predetermined height. The sheet-material retaining conveyor is disposed to be movable in a direction in which the sheet materials in the stacked state elevate.

Abstract: A sheet-member separation device includes a first air blower, an attractor, a conveyor, a second air blower, and an adjuster. The first air blower blows air onto a front side of a stack of sheet members in a sheet-member conveyance direction. The attractor attracts an uppermost sheet member floated from the stack of sheet members by the air blown from the first air blower. The conveyor conveys, in the sheet-member conveyance direction, the sheet member attracted by the attractor. The second air blower blows air toward a lateral side of the sheet member. The adjuster moves the second air blower and the attractor together to adjust positions of the second air blower and the attractor in the sheet-member conveyance direction.

Abstract: A stacking apparatus includes a conveyance unit, a stacking unit, and a separation member supply unit. The conveyance unit conveys sheets for circuit board. The stacking unit stacks the sheets. The separation member supply unit supplies a separation member to separate the stacked sheets at any position. The separation member supply unit places the separation member on the sheet in being conveyed.

Abstract: A sheet conveyance apparatus includes: a placement part configured such that stacked sheets are disposed on the placement part; a housing including an open/close part and accommodating the placement part, at least a portion of the open/close part being configured to be opened and closed; and a suction unit connected with the housing, and configured to draw gas from an interior of the housing.
