Abstract: When an electrode (29) such as a grid applied with a negative voltage is installed in front of an objective lens (23), low energy electrons among secondary electrons (25) generated from a sample (24) by an electron beam or the like is reflected by the electrode to come into a detector (22) installed in the sample (24) side, while electrons of higher energy are not detected, since they are not reflected by the electrode. Accordingly, since only the electrons of lower energy of the secondary electrons can be detected by discriminating the secondary electrons by the energy, it is possible to obtain a detection signal, e.g., rich in the information on the surface state of the sample.

Abstract: 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).

Abstract: A pretreatment method for element analysis of metal samples removes contaminants on the surface of the metal sample by sputtering while at least one electrode for sputtering is cooled. A pretreatment apparatus for element analysis of metal samples for performing the method includes a cathode for holding the metal sample, anodes arranged to counter the cathode for sputtering, and a pretreatment chamber to store the cathode, anodes and metal sample under an inert gas atmosphere. The apparatus includes a cooling device for cooling at least one of the electrodes. The cathode and the anodes may be interchanged in the apparatus.

Abstract: 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.

Abstract: 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.

Abstract: 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.
