A cross-flow fan includes a plurality of fan blades. The fan blade has an inner edge portion arranged on an inner circumferential side and an outer edge portion arranged on an outer circumferential side. In the fan blade, a blade surface extending between the inner edge portion and the outer edge portion is formed. As the fan rotates, an air flow which flows between the inner edge portion and the outer edge portion is generated over the blade surface. The fan blade has such a blade cross-sectional shape that a recess is formed in the blade surface. The recess is arranged at a position closer to the outer edge portion than to the inner edge portion and formed to extend from one end to the other end of the fan blade in a direction of a rotation axis of the fan.

An endoscope apparatus includes a front end section which is rigid, and a flexible tube which has a bent portion. One end of a tube which can be bent is fixed to a lens barrel which holds an optical mechanism having a movable section. The tube is extended in a longitudinal direction of the flexible tube of the endoscope apparatus, and at least a part of a shape memory element is accommodated inside the tube. One end of the shape memory element is fixed to an end of the tube, which is not fixed to the lens barrel, and the other end of the shape memory element is mechanically connected to the movable section of the optical mechanism which includes the movable section. Due to expansion (elongation) and contraction of the shape memory element, relative positions of the movable section of the optical mechanism which includes the movable section, and one end of the tube fixed to the lens barrel are changed.

A parallel conductor comprising a bundle of a plurality of high temperature superconducting wire materials, ends of the wire materials being electrically connected to each other, wherein each of the high temperature wire materials has at least one short-circuited portion where the wire materials are connected by means of a non-superconducting conductive material, and portions other than the short-circuited portion being covered with an insulating material.
摘要:
A superconducting wire, a method of manufacturing the superconducting wire, an antenna coil and a NMR system are disclosed. At least a superconducting material, a paramagnetic material and a diamagnetic material are closely attached and integrated with each other to form a longitudinally continuous wire. The paramagnetic material and the diamagnetic material are arranged in such a manner that the magnetic properties of the paramagnetic material and the diamagnetic material substantially offset each other in the longitudinal and diametrical directions. A superconducting layer is exposed to a part or the whole of the outer periphery of the wire. A low-resistance material layer is formed inside the superconducting layer.
摘要:
An antenna coil is formed by a wire rod obtained by combining and integrating two or more kinds of materials having different magnetisms. The wire rod has a circular or polygonal cross sectional shape. The two or more kinds of materials having different magnetisms are combined so that the magnetisms of the combined materials are set off. The wire rod is wound around a bobbin so as to have a solenoid shape. Desirably, the low-magnetic wire rod is placed in an atmosphere whose temperature has been reduced to 10° K or less or superconductive filaments are formed in the outermost layer. Preferably, a part of the superconductive filaments are exposed.
摘要:
A sheet discharging device has a conveying weight for pressing a conveyed sheet to a caterpillar belt. The pressing force of the weight is increased both when the sheet is discharged from the caterpillar belt to a placement tray, and when the sheet is switched back and conveyed to the bottom of the caterpillar belt. The pressing force of the weight is increased concurrently with the driving of a paddle provided at an outlet of the placement tray. The pressing force is increased by a rubber piece provided on a paddle driving shaft that rotates out of phase with the paddle, so as to engage and press the conveying weight at a predetermined time. The device is capable of reliably conveying a wide variety of sheets onto a tray and transferring the conveyed sheets to a predetermined tray position.
