Abstract: PURPOSE:To facilitate taking out of a solidified sample and to prevent the generation of cavities and pinholes in the solidified sample by forming a reducing path consisting of a cylindrical boss made of a nonmetallic material having small thermal conductivity to a partition wall between an inflow chamber and a sampling chamber. CONSTITUTION:A container 3 has the inflow chamber 6 facing an inflow port 4 opened to a side part and the sampling chamber 8 communicated with the chamber 6 via the reducing path 7 disposed below the inflow chamber. A barrier part 9 is projected to the molten metal flow passage from the inflow port 4 to the sampling chamber 8. The reducing path 7 is formed of the cylindrical boss 11 provided on the partition wall 10 which partitions the inflow chamber 6 and the sampling chamber 8. The tip of the boss 11 is positioned upper than the inside base of the port wall of a nozzle member 4a forming the inflow part 4. The excess molten metal in the inflow chamber 6 flows out of the inflow port 4 and the excess molten metal does not remain in the inflow chamber 6 if the container is pulled up after the molten metal is sampled. The molten metal is filled into the sampling chamber 8 and the reducing path 7 while said metal is slowly cooled if the boss 11 is formed of the nonmetallic material having the small thermal conductivity. The generation of the cavities and pinholes in the solidified sample is thus obviated.

Title: Fiber type wavelength conversion element
Inventor: CHIKUMA KIYOBUMI
IPC: G02F1/37
Filed: 1990-07-17
Abstract: PURPOSE:To improve the output level of a second harmonic wave by selecting one of the induction main axes of a core material and further adopting the crystal orientation to rotate the other two induction main axes around the selected one induction main axis, thereby making the refractive index to the second harmonic wave smaller than the refractive index to linear light. CONSTITUTION:This element consists of the circular cylindrical core 10 constituted of a nonlinear optical crystal and a cylindrical clad layer 20 concentrically enclosing the core 10. The linear light which is the linearly polarized light of a frequency omega entering and propagating in the central axis direction of the core 10 is converted to the refractive index of a frequency 2omega having the oscillation plane perpendicular to the oscillation plane of the linear light. The element consists of the nonlinear optical crystal satisfying n<omega>>=n<2omega> when the refractive index to the linear light is designated as n<omega> and the refractive index to the second harmonic wave as n<2omega>. The induction main axes are suitably selected and further the selected induction main axes are rotated in the direction of central axis of the core 10, by which overlap integration of the electric fields of the linear light and the quadratic light is increased. The second harmonic wave is generated with higher efficiency in this way.
