Title: Irradiation test device
Inventor: WADA TAKASHI
IPC: G21C23/00
Filed: 1991-02-05
Abstract: PURPOSE:To enable an irradiation test for an unknow fuel element to be safely made by sealing the lower sealing section of a specimen housing container with a first fusible alloy which is unsealed at furnace temperature before operations, and concurrently sealing its upper sealing section with another fusible alloy which is unsealed at temperature increased in response to excessively increased temperature within a furnace. CONSTITUTION:This device including a specimen housing container 4 is loaded in a furnace core. When an operation is started, temperature in sodium is raised, a first fusible alloy 13 at the lower section side starts melting in the halfway up to 370 deg.C, seal at the lower section side of a double tube is released. Concurrently, sodium starts penetrating into a gap 5 so as to push a gas layer. The sodium level can be adjusted by the pressure of sealing gas and a sealing position. When fuel, temperature becomes high by some reasons during irradiation, and when the temperature of coolant at the outlet is raised close to the melting point of a second fusible alloy 18 at the upper section side, a sealing port 22 communicated with a heat insulating layer is released, gas in the gap is emitted, and sodium 23 comes upward from the lower side, so that it fills up the gap 5. By this constitution, heat removing capacity is increased so as to allow the temperature of both fuel and coolant at the outlet to be quickly cooled, so that the test can thereby be safely made.

Inventor: KIKUCHI TOSHIHIRO
IPC: C25D5/36
Filed: 1995-01-31
Abstract: PURPOSE: To produce an Sn plated steel sheet excellent in high speed continuous weldability, for use in a welded can body prepared by means of lap resistance seam welding, by providing an Sn plating of specific coating weight onto a steel sheet containing specific amounts of C and Mn in a surface layer. CONSTITUTION: Lap resistance seam welding is applied to an Sn plated steel sheet by using a can body welding machine, by which a welded can body is obtained. In this Sn plated steel sheet, Sn coating weight is regulated to (0.25 to 23)g/m<2> . Further, the contents of C and Mn in the surface layer of the steel sheet to be the substrate for Sn plating are regulated to 0.001-0.18wt.% and 0.10-0.6%, respectively, on the average in the region between the outermost surface and a position at a depth of 20μm from the outermost surface. By this method, the dispersion of welding resistance can be reduced and welding operation can be made high efficiency, and high speed continuous welding is made possible.

Title: Interferometer
Inventor: KIMURA MITSUTERU
IPC: G01B9/02
Filed: 1979-02-14
Abstract: PURPOSE: To facilitate the discrimination of the manner of continuation of an interference fringe on the step of the surface of a sample, by irradiating the sample with two monochromatic light beams different in wavelength so that Fizeau's interference fringes are independently generated by the monochromatic light beams.  
     CONSTITUTION: Light from a light source is changed into a monochromatic light beam of λ 1  in wavelength by the first monochromatic light generator B and changed into the second monochromatic light beam of λ 2  in wavelength by the second monochromatic light generator C. Both the monochromatic light beams are made coincident in optical axis with each other and introduced into a reflection interference microscope D. When a measured sample 13 has a step d defined by a lower surface region I and an upper surface region II demarcated from each other by a plane X-Y, an interference fringe a shown by a full line is produced by the monochromatic light beam of λ 1  in wavelength and another interference fringe b shown by a dotted line is produced by the other monochromatic light beam of λ 2  in wavelength. In the parts α, β of the regions I, II, the fringe a α  is close to the other fringe b α . Since the interference fringes in the regions I, II continue from the part α to the other β, the depth d can be accurately determined by only the monochromatic light beam of λ 1  in wavelength as a shutter 8 is closed.

Abstract: PURPOSE:To reduce a packaging area onto a substrate as well as simplify arrangement design of a coil, etc. by a method wherein a plurality of open magnetic path coils are provided on a surface and a rear face of the substrate respectively so that leakage flux of each coil is passed through a magnetic sensor. CONSTITUTION:In a system for sensing a plurality of currents, a magnetic sensor 3 can be shared by supplying different currents to each of coils 2.

In a system for sensing one current, same current is flowed to each of the coils 2 so that the currents are allowed to flow in a direction that magnetic fields produced at the respective coils 2 intensify each other at the position of the sensor 3, thereby reducing size of the coil 2. In addition, since the coils 2 are provided on a surface and a rear face of a substrate 1, the substrate can be efficiently utilized. Further, since open magnetic path coils are employed, a unit 10 for sensing current can be compacted.
