IPC: G01N27/20
Filed: 1989-04-21
Abstract: PURPOSE:To monitor the deterioration on ageing of the structural material in an atomic reactor by using a mechanism with the strain increasing in accordance with the operating time of the reactor in the loading system of a test piece container. CONSTITUTION:The pellets 2a-2f obtained by sintering a mixture of Al2O3 and B4C are enclosed in the test piece container 1 made of stainless steel, and a current from a DC power source 6 is intermittently switched by a current polarity switching device and supplied to the feeder terminals 8a and 8b of the container 1 through a lead wire 7. The measuring terminals 3 connected to a multiplexer through a lead wire 4 are switched by the potential difference, and the potential difference is measured by micropotentiometers 5a-5f. When the internal stress in the container 1 is gradually increased by the cubic expansion of the pellets of the mixed powder of Al2O3 and B4C in the container 1 in the atomic reactor and generation of gaseous H2, the material of the container 1 is progressively deteriorated in the process of operation by the thermal stress. Consequently, the state can be measured and monitored with the lapse of time.

Title: Dust-proof net for heat exchanger
Inventor: KIKUCHI KOICHIRO
IPC: F24F13/28
Filed: 1994-04-13
Abstract: PURPOSE:To make a uniform air flow passing in a heat exchanger by a method wherein a main body of a net is divided into a central region and a peripheral region, a region having a large amount of aeration has a fine mesh and another region having a small amount of aeration has a rough mesh. CONSTITUTION:This net is divided into a central region 4 arranged in a rectangular form at a central part of a main body 3 of the net and a first, a second and a third peripheral regions 5, 6 and 7 arranged in annular form in a rectangular shape at the outer periphery of the central region. The central region 4 has the finest mesh, but the net has a larger mesh size as the mesh goes from the central region toward its far peripheral region. This is due to the fact that an average aeration amount per unit area in a normal vehicle is high as it approaches its central region. A size of each of the mesh is set in such a way that an aeration amount per unit area at each of the component parts of a heat exchanger. With such an arrangement as above, it is possible to get a heat exchanging performance at each of the components of the heat exchanger as much as possible. That is, the mesh size of the dust-proof net 2 is determined such that it may show the best matching with the heat exchanger.

IPC: C23C4/06
Filed: 1982-06-11
Abstract: PURPOSE:To improve rust preventive performance, by coating a special primer on the metallized surface of a ferrous metal and forming the paint film of a thermosetting or thermoplastic resin. CONSTITUTION:A pretreatment such as degreasing or rinsing is first applied on the surface of a ferrous metal, whereafter a hard metallic layer of zinc, aluminum or the like is formed by metallization on said surface. When a primer layer of a high temp. curable resin is coated thereon in a state of soln., the resin infilters the inside of the pinhole in the metallized surface and cures after the evaporation of solvent, thereby forming a film.
