Abstract: A feeding apparatus includes a pressing plate movable up and down configured to allow recording media to be stacked thereon, a feeding roller configured to feed recording media stacked on the pressing plate, an urging unit configured to urge the pressing plate in a direction to come close to the feeding roller, and a moving-away unit configured to cause the pressing plate to move away from the feeding roller against an urging force from the urging unit. The moving-away unit causes the pressing plate to move so that a distance between the uppermost recording medium being stacked and the feeding roller becomes approximately constant regardless of an amount of recording media stacked on the pressing plate.

Abstract: A recording apparatus includes moving rollers and a feeding roller. The moving rollers move a set first sheet in a direction intersecting a conveying direction.

Abstract: The feeding device includes a storage unit, a feeding roller which rotates while contacting the uppermost sheet stored in the storage unit to move the uppermost sheet forward, a separation plate disposed forward in the movement direction of the uppermost sheet and provided with an inclined surface inclined with respect to the movement direction, and a separation auxiliary member is disposed along the inclined surface of the separation plate and operated by a force received when the uppermost sheet comes in contact. The separation auxiliary member includes a rotation shaft parallel with the inclined surface, and a first resistance part rotating about the rotation shaft as the center from an initial position projecting from the inclined surface to an embedded position embedded in the inclined surface as a friction coefficient of the first resistance part is higher than that of the inclined surface and the received force is increased.

Abstract: The cell observation using a conventional well plate takes much costs. Each well 3 being opened at a top plate 2a of the well plate 1 has a diameter reduced portion 32 which inner circumferential surface 32a is conically hollowed. At a lower portion of the diameter reduced portion 32 is formed an inserting hole 33. In a detecting portion 4, an outer circumferential surface of a round-bar reference electrode 41 is covered by an insulating portion 42. The detecting portion 4 has an upper end portion 4a and a lower end portion 4b which outer circumferential surface is exposed to an outside without being covered by an insulating portion 42. On an upper side above the lower end portion 4b is formed a diameter expanded portion 4c in which an outer circumferential surface of the insulating portion 42 is covered with a measuring electrode 43. The detecting portion 4 is fixed to a well 3 whose diameter expanded portion 4c is inserted into an inserting hole 33 and its upper end portion 4a is contained in the well 3.

Abstract: A fuel cell module, wherein slopes of a same angle ? relative to a bottom face are formed on both side faces to form a recessed groove in a tapered shape. Since the angle ? is provided to the side faces of the recessed groove, the exhaustion of gases from the accumulation of gasses to the outside can be assisted by the side faces with the angle ? more than in a case where the side faces of the recessed groove are formed in right angled shapes even if the accumulation of gases is produced between an adhesive agent and the inner surfaces of the recessed groove when first and second separators are joined to each other for modularization by covering the first separator on the second separator. Thus, the accumulation of the gases can be prevented from occurring.

Specifically, the pharmaceutical preparation to be dispersed before administration contains active granules containing a pharmaceutically active substance having an average particle diameter of 5 mm or less and a thickening agent, and can be administered through an NG tube by dispersing in water before administration.

Abstract: A sheet material feeding apparatus has a rotatable pressure plate for stacking sheet materials, a pickup roller for feeding the sheet material stacked on the pressure plate, a feed roller for feeding the sheet materials fed by the pickup roller and a separation roller contactable with the feed roller. A registration roller corrects oblique feeding of the sheet material by being abutted against the separated sheet material by the feeding roller and the separation roller, and after the registration roller rotates in synchronism with the pickup roller and the feed roller to start feeding the sheet material, pressure of the pressure plate against the pickup roller is released, and thereafter the feed roller and the separation roller are spaced apart from one another.

Abstract: A sheet supplying apparatus has a first stacking portion with a sheet, a second stacking portion movable relative to the first stacking portion, and a supplying roller used in common to the first and second stacking portions, for supplying the stacked sheets. The second stacking portion is movable between a retreat position where the second stacking portion retreats so that the sheet can be supplied from the first stacking portion, and, a supply position where the second stacking portion advances, so the sheet can be supplied from the second stacking portion.

Abstract: The invention relates to a fuel cell stack structure capable of suppressing a drop in voltage resulting from flooding or contamination at an end in a direction in which cells are laminated, particularly in a cell at a gas outlet/inlet end. In this fuel cell stack structure, a layer which is irrelevant to power generation and in which a gas flow channel is formed is provided at least at a gas outlet/inlet end of a laminated-cell body of a fuel cell such as a solid-polyelectrolyte fuel cell. The layer is constructed of a dummy cell having a gas flow channel but no MEA. In addition, according to this fuel cell stack structure, both a fuel gas flow channel and an oxidative gas flow channel are formed in one face of the layer which is irrelevant to power generation and in which the gas flow channels are formed.

Abstract: A tube pump reduced of the burden against pump driving caused by dragging of a tube by a pressurizing roller. Specifically, guide members are disposed in the respective introduction portions at between the guides. Namely, the guide members are arranged nearby the extensions of the circumference of the arcuate guides and radially with respect to the center of the circumference. Due to this, the pump tube, the roller is to drag, is sustained by the guide member, to prevent the tube from increasing its deformation due to dragging. Thus, the tube can be prevented from being dragged in a manner forming a resistance to the roller. As a result, the pump motor, etc. can be prevented from being burdened with an increasing load.
