Title: Inspecting instrument for through-hole
Inventor: MITA KIKUO
IPC: G01N21/88
Filed: 1986-06-19
Abstract: PURPOSE:To improve the detection performance for a defect by using two optical systems which form images on a photodetector and effectively detecting only light leaking from a defect generated in a through-hole to be inspected. CONSTITUTION:A light shield material 11 is interposed between the through-hole 11 to be inspected and optical systems 2 and 13 almost in parallel to a board 1 and provided so that transmitted light from the through-hole 10 is not incident on the optical system 13. Further, a slit 15 is made in the light material so that only leaking light from the hole 11 is passed. Then if there is leaking light caused by a plating defect part 9 from the hole 11, the light reaches the optical system 13 through the slit 15. At this time, even if an adjacent through- hole is present and there is transmitted light from it, it is cut off 14 and never reaches the optical system 2. The shield material 14 is so arranged that light incident on the optical system 2 from the adjacent through-hole is not cut off. Thus, only the leaking light from the hole 11 reaches the optical system 13, so a dark level is accurately obtained and the detection performance for the defect is improved.

Title: Refractory-covered long size body
Inventor: YUKIMI NOBUO
IPC: F27D1/00
Filed: 1988-06-10
Abstract: PURPOSE:To provide a castable refractory comparable to a metallic fiber-loaded refractory by providing a refractory comprising bamboo fibers added in a specified amount to a refractory material having one of various compositions, on the outer periphery of a pipe-shaped core material. CONSTITUTION:A fiber-loaded castable refractory used for a lance is higher in bending strength at high temperatures though poorer in compressive strength and bending strength at normal temperature, as compared with a stainless steel fiber-loaded refractory. The refractory used for the lance has a lower thermal conductivity and, therefore, higher heat insulating properties. The amount of the bamboo fibers is preferably 0.2-3.0% based on the total weight of the refractory. A refractory loaded jointly with 0.2-3.0% of bamboo fibers and 1-4% of stainless steel fibers shows enhanced strength at normal temperature while maintaining the merits confirmed for the refractory loaded solely with the bamboo fibers, namely, the favorable heat insulating properties and high-temperature strength.
