Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To suppress a temp. rise with a simple structure by forming an upper surface of a rotary drum in an overall opened shape and providing notched parts for disturbing air in the rotary drum on an inner periphery. SOLUTION: The upper surface of the rotary drum 3 is formed in the overall opened shape, and many notched parts 17 are provided on the upper end inner peripheral part of the rotary drum 3. The notched parts 17 are formed on 18 places at even intervals, and its shape is a semicircular recessed shape, and are engraved in the direction intersecting with the rotational direction of the drum. Since the upper surface side of the rotary drum 3 is opened overall, the drum isn't filled with the heat caused by ICs 11 for a recording amplifier. When the rotary drum 3 is rotated, the air in the drum is disturbed by air resistance in the recessed parts 17, and since the matter that the drum is filled with the heat caused by the ICs 11 for the recording amplifier is prevented effectively, the temp. rise in the vicinity of the ICs 11 is suppressed, and the temp. of the ICs 11 is made appropriate.

Title: Nuclear waste storage module
Inventor: JIYOSEFU MOORISU MAAKOOBUITSUT
IPC: G21F9/36
Filed: 1990-03-30
Abstract: PURPOSE: To realize shielding action effectively by a structure wherein one waste enclosure is contained in the inner cavity and an air gap defined by the waste enclosure and a module is partially filled with a granular filler. CONSTITUTION: An air gap is formed between a waste enclosure or a package 26 and the side part of a vessel 12 in a cylindrical inner space 20 and filled with a granular filler 36. The granular filler 36 is compacted around the waste enclosure or a package 26 which is thereby substantially immovable in a module 10 and prevented from being shifted in the module 10 during transportation or processing. In this regard, the granular filler 36 makes the waste enclosure package 26 immovable in the storage module thus providing advantages which can not be obtained through the use of a hardening material such as cement.
