There is provided with a method for manufacturing an isoxazole derivative at a high yield and without discharging waste products, and a novel isoxazole derivative. An isoxazole derivative expressed by Formula (8) is produced by reacting a 1-alkyne compound expressed by Formula (7) with iron(III) nitrate in the presence of acetone or acetophenone: (where R1 is an alkyl, cycloalkyl, phenyl, or other such group); and (where R2 is a methyl or a phenyl).

In a sludge treatment tank, members made of a glass long-fiber reinforced foamed plastic composite material are used as formworks in construction and then left as an inside wall member. The composite material functions as formworks in a construction method as well as applies an insulating property and a corrosion resistant property to the sludge treatment tank and further realizes labor saving in a field of construction works, the provision of a good working environment and the reduction of a period of construction work.

There is disclosed a rotation axis fine adjustment apparatus for finely adjusting rotation of a mounting portion rotatably mounted on a rotation axis with respect to a base portion through a fastening frame by suitably fastening and finely adjusting the rotation axis. It comprising an outer tube inserted in and fixed to the mounting portion with its end portion projecting outward; an intermediate hollow axial body formed at its outer peripheral surface with a flange portion and at its inner peripheral portion with a female thread portion, and inserted into inside of the outer tube and concentrically secured to the outer tube by screw means with the flange portion abutted against the end portion and other outer tubes kept being spaced apart from the outer tube; a fastening intermediate hollow axial body rotatably attached to an inner side of the outer tube at outside of the intermediate hollow axial body, and fixed at its one end with a fastening control handle; and a fine adjustment axial body formed with a male thread portion for being in threaded engagement with the female thread portion and reciprocally movably attached to an inner side of the intermediate hollow axial body in order to finely rotate the mounting portion, and coaxially fixed at its one end with a fine adjustment control handle with respect to the fastening control handle.

A nail remover according to the present invention includes a tool head having a guide bore extending linearly through the head in a longitudinal direction, a push-rod slidably mounted in the guide bore of the head between a retracted position at which a free end of the push-rod is located in the guide bore and an extended position at which the free end of the push-rod protrudes from the guide bore, a driving device for advancing the push-rod from the retracted position to the extended position, and an actuator for activating the driving device. At least a portion of the peripheral wall defining an outlet of the guide bore is tapered toward an outboard edge of the wall so as to make it easy to introduce a nail into the guide bore. In operation, the guide bore receives the portion of a nail protruding from a plate such as a piece of plywood. Then the nail is straightened by aligning the guide bore with the axis of the nail and, thereafter, the push-rod is driven towards the extended position so as to drive the nail out of the plate.

[Object] The present invention provides an X-ray irradiation device capable of adjusting the energy of X-rays in a wide range, and an analysis device equipped with the X-ray irradiation device.[Solving Means] An X-ray irradiation device according to an embodiment of the present invention focuses X-rays emitted from an X-ray generation mechanism to a predetermined focal position by a focusing mechanism. The X-ray generation mechanism has a structure which generates a plurality of X-rays having different wavelengths. The focusing mechanism has a structure in which the plurality of X-rays are focused to the same focal position by focusing elements having diffraction characteristics suitable for the wavelengths of the respective X-rays generated by the X-ray generation mechanism.

The present invention provides a pre-treatment apparatus for an analytical metal sample, the apparatus including (1) a treatment chamber having a sample charging port which can be opened and closed and provided at the top of the chamber, a sample discharging port which can be opened and closed and provided at the bottom of the chamber, and a gas inlet and gas outlet, (2) a sample carrying bar joined to a sample holder also used as a sputtering electrode, and provided to pass through at least one side wall of the treatment chamber so as to be substantially horizontally movable and axially rotatable, and (3) a sputtering counter electrode at least having portions arranged opposite to each other in a region not inhibiting the charge and discharge of an analytical metal sample so that the sample holder can be arranged in the counter electrode. The present invention also provides a pre-treatment method capable of simply cleaning the surface of the analytical metal sample by using the pre-treatment apparatus and preventing re-contamination of the cleaned sample by exposure to the air or the like. Furthermore, the present invention provides an analysis apparatus provided with the pre-treatment apparatus to permit high-accuracy quantitative determination of trace elements of metals.

A base board device for detachably mounting a measuring instrument such as a transit. The base board device has a centering telescope for locating the base board directly above a point on the ground. The centering telescope has a mark in the eyepiece which defines a viewing axis directed vertically downwardly. In order to determine whether or not the viewing axis as defined by the mark is directed accurately downwardly, the centering telescope is used. To facilitate that use, the base board is formed at the center thereof with an aperture so as to make it possible to observe the vertically downward point through the centering telescope.
