Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To improve the productivity of a sintering machine by regulating the fixed carbon concn. on a sucked air outlet side layer and compounding oxidizable iron-component contg. materials. SOLUTION: The fixed carbon concn. in the lower layer, i.e., the compounded raw material layer on the sucked air outlet side is specified to 0 to <=2wt.% and in turn, >=1 kinds of any among metal iron, FeO, Fe3 O4 which are the oxidizable iron-component contg. material are compounded as fuel in this method.

Title: Refractive index distribution measuring device for cross section of optical waveguide
Inventor: NIKORASU JIZAN
IPC: G01N21/41
Filed: 1991-04-19
Abstract: PURPOSE:To utilize projection light effectively by inclining an optical axis of a projection system to an end surface of an optical waveguide part in a refracted near field(RNF) method. CONSTITUTION:In a refractive index distribution measuring device in a refracted near field(RNF) method, an optical axis 13 of a projection system 12 is inclined toward a counter optical waveguide part 3 side with respect to an end surface of an optical waveguide substrate 1. The maximum incident angle thetamax thus becomes a value added with an inclination angle of the optical axis 13. A light receiving part, that is, at least a light receiving surface of a detector 5 is sufficiently large to the outer side of a leaking light flux 4, while an end edge 7 of the light receiving surface is disconnected for the center side, so that a part of the optical waveguide part side of the light flux 4 may not received so as to determine refraction factor distribution. Since most of projected light thus leaks from an optical waveguide part 3, the projected light can be utilized effectively, and the maximum incidental angle thetamax can be set large to increase received light quantity even when an aperture number of an objective lens 8 is small, and further an S/N ratio can be improved.
