摘要： PURPOSE:To recover separated, evaporated metal by liquid carrier metal and continuously take it out by letting liquid carrier metal flow uniformly from the high level side to the low level side on the liquid carrier metal holding part under an inclined evaporated metal recovering plate. CONSTITUTION:A metal 29 to be evaporated in an evaporation crucible 2 is heated and evaporated by irradiating electron rays from an electron gun 3 in a vacuum container 1. After passing a focusing device 4, a laser beam 5 of a specific frequency is projected on this evaporated metal and metal to be separated is ionized selectively. Then, electrolytic metal is adsorbed by a recovering plate 7, separated and recovered. Neutral evaporating metal is brought into contact with the lower surface of a neutral metal recovering plate 8 which is inclined by a prescribed angle. The lower surface of this recovering plate 8 is covered with stretched wire, etc., as a liquid carrier metal holding structure and liquid carrier metal is poured uniformly from the high level side to the low level side in a storing tank 16. Said neutral evaporated metal is recovered by this carrier metal, flows and is taken out outside the vacuum container 1 through a recovering through 19, a recovering tank 20, a duct 21 and separated recovered by a neutral metal separating and refining device 22 from the carrier metal.

摘要： PROBLEM TO BE SOLVED: To provide a liquid-leak detecting body by which the leak of a liquid can be detected immediately. SOLUTION: In this liquid-leak detecting body, a sheet material 9 which is arranged in the lower part of a transfer tube 2 is provided, and a thin foillike conductive passage 10 which is arranged on the sheet material 9 is provided. The sheet material 9 is formed of a polyethylene resin which has an electric insulating property and which can be melted when a high-temperature liquid 1 such as a molten salt or the like is brought into contact. The conductive passage 10 is formed by transferring or vapor-depositing a metal. When the high-temperature liquid 1 which is leaked in the coupling part or the like of the transfer tube 2 is dropped onto the sheet material 9, the sheet material 9 is fused, the conductive passage 10 is broken down, and the electrification of a current for detection is cut off.

摘要： PURPOSE:To enhance the brazing strength, increase the locating accuracy of a rib body, and enhance the easiness in provisional fixing operations by suppressing generation of eddy current in a small wall thickness part, ensuring the strength against the vacuum with a large wall thickness part and number of ribs, and furnishing the rib body with a reinforcement part. CONSTITUTION:A number of ribs 3 are furnished on the outside of a chamber body 2. The wall thickness of the chamber body is varied along the circumference, wherein the part close to a magnet M and easy to generate an eddy current is embodied as a small wall thickness part 2a and the other parts are formed as a large wall thickness part 2b. To manufacture such a vacuum chamber 1, a rib body 30 isinstalled on the outside of a tubing 20 having a uniform thickness, and a brazing takes place to make them consolidated. The rib body is provided with a through hole 31 to admit insertion of the tubing and a reinforcement part 32 which is consolidated with the tubing to form a large wall thickness part. It is recommended that a brazing sheet consisting in a laminate of a parent material plate 30a and brazing substance 30b is used as material to the rib body.

摘要： PURPOSE:To simplify structure to facilitate manufacturing of a calorimeter by laminating a plurality of radiation absorbing plate members, formed into nearly the same length, in the direction along a particle orbit to constitute a unit block. CONSTITUTION:Lead plates 24 as radiation absorbing plate members are laminated in arrangement per unit angle DELTAeta in the radial direction from a center position 22 so as to constitute a whole body of a calorimeter 21. A unit block 42 is formed of a plurality of the laminated lead plates 24, and multiple unit blocks 42 are sequentially stacked along a eta angle. In the unit block 42, a plurality of the lead plates 24 of nearly the same length are laminated in a rectangular shape via specified intervals in the direction along an axis (eta=90 deg.), plates are applied to the top and underside thereof, support rods are made to penerate them in the up and down direction and fastened from both sides by means of nuts. Since the lead plates 24 of the same length are used in order to facilitate manufacturing, corner parts of the unit block 42 are protruding or retreating from the unit angle DELTAeta, however, no problem is involved in measurement as long as a height of the unit block 42 is not made excessively high.
