Title: Production of welding material of low weld crack sensitivity
Inventor: SERIO NAOYUKI
IPC: B23K9/23
Filed: 1978-09-20
Abstract: PURPOSE: To obtain the weld zone which does not produce any cracking even under ordinary temperature by welding the steel materials containing a slight amount of the specific elements with a coated electrode of considerably reduced hydrogen source.  
     CONSTITUTION: One or more kinds of REMs (rare earth elements) are added at 0.002W0.30% to ordinary mild steel or high tension steel or Ca st 0.001W0.02% or both are added to provide base metals. When these are welded by using such an extra low hydrogen type coated electrode that the diffusible hydrogen amount of deposited metal becomes 1ppm or under, then the hydrogen penetrated from the deposited metal into the base metals is absorbed by the REMs and Ca and therefore the crack sensitivity of the weld heat affected zone is considerably reduced.

Title: Casting device
Inventor: MOTOYAMA KENJI
IPC: B22C9/00
Filed: 1995-05-15
Abstract: PURPOSE: To improve the quality and the precision of a cast product and to reduce the cost required for deburring work by closing the upper part of a reduced pressure flask with a film and communicating a lower chamber with an evacuation source. CONSTITUTION: The upper opening part 3d of the reduced pressure flask 3 is closed with the film 5, and in the lower chamber 3b, gas exhaust hole 3c is arranged and communicated with the evacuation source P. When the pressure in the lower chamber 3b of the reduced pressure flask 3 is reduced with the evacuation source P, the pressure of an upper chamber 3a is reduced through a filter 4, and since the opening part 3d is closed with the film 5, the atmospheric pressure exerts on the film 5, but the pressure of the chamber 3a is equalized with that of the chamber 3b through the dry sand 6 and the negative pressure is uniformly applied to the whole surfaces of a cope 1 and a drag 2. At the time of pouring molten metal into a sprue 7, the gas generated in the cope 1 and the drag 2 is quickly diffused into the flask 3.  By this method, the development of a gap of the joining surface between the cope and the drag is restrained by the uniformity of pressure applied to the molds together with the effect of rapid diffusion of the gas, and the development of burr is prevented.

Title: Laser interferometer
Inventor: KENESU JIEI UEIN
IPC: G01B9/02
Filed: 1989-05-09
Abstract: PURPOSE: To improve the detection capability of interference fringes due to measurement beams by an interferometer by providing a small aperture diaphragm and inserting it into the front of a light receiving lens. CONSTITUTION: A small aperture 30 is provided immediately before a focusing lens 23 of a detector. The aperture 30 becomes the path of a part within the section of the aperture 30 out of recombination beams 22. Then, the lens 23 focuses a part 31 of the beams 22 that pass the aperture 30, and only that portion is detected and is sent to a high-gain light receiver 32. In this case, only a desired region of reflection light is passed by the aperture 30 and remaining reflection beams are not passed. Also, the large part of the beams 22 is not allowed to reach a light receiver 32. Since the aperture 30 attenuates beams 22, an interference pattern decreases also the section of beams being averaged by the light receiver 32.  When the section of interference fringes generated by wavefront distortion noise is larger than the area of the aperture 30, signal quality decreases and the contrast between fringes increases. It means that an S/N ratio increases.
