Title: Apparatus for removing inclusion in molten steel
Inventor: TAKAHASHI MASAMITSU
IPC: B22D11/10
Filed: 1988-02-26
Abstract: PURPOSE:To restrain clogging-up and to remove inclusion at high efficiency by arranging refractory-made filter between one pair of weirs. CONSTITUTION:Molten metal 1 passes through a first weir 4, filter 5 and a second weir 6 in order and flows in a vessel. The molten steel 1 is filtered with the filter 5 between them to remove the inclusion. In this case, as one pair of weirs are arranged in the vessel, flowing force or impact force of the molten steel 1 are received with the weir. Therefore, the impact force of the molten metal is not impressed to the filter 5 arranged between these weirs 4, 6 and further even if the flowing force of the molten steel 1 is received, the filter 5 is supported with the second weir 6 and the deformation or the breakage is not developed. Further, as some gap exists between the first weir 4 and the filter 5, the molten steel passed through the first weir 4 is spread to the whole face of the filter 5 and the molten steel passing-through area of the filter is wide and the clogging-up of the filter is restrained.

Abstract: PURPOSE:To make construction simple, low loss and inexpensive by changing over optical path by using curved optical fibers. CONSTITUTION:The photo switch is constituted by input fibers 21a-21d, output fibers 22a-22d and bypass fiber 23. The bypass fiber 23 is opposed to the end faces of the fibers 21a and 22a. A member 24 is formed by epoxy resin or the like by way of the thin film elastic material 25 having the same refractive index as that of the core of the optical fiber. Further, the member 24 is connected to a step motor 26 whose center of rotation aligns to the center of where each fiber is arrayed.

Then a TiN film 18 is formed on the Ti film 17 by performing sputtering using a Ti target so that the substrate 11 cannot be exposed to plasma in an inert gas atmosphere containing nitrogen. Thereafter, a TiSi, film 19 is formed at the part where the Ti film 17 is in direct contact with the substrate 11 by heating the laminated film of the films 17 and 18. Therefore, the resistance of the laminated film can be sufficiently lowered even when the thickness of the Ti compound film is reduced to 50nm.
