Title: Amorphous casting refractory for vessel lining used for melted metal and its cast product
Inventor: OSHIMA AKIHIRO
IPC: C04B35/66
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To obtain an amorphous casting refractory excellent in thermal spalling resistance and weather resistance by specifying the purity, granule diameter and compounding amount of electrically melted magnesia clinker as an aggregate. SOLUTION: This amorphous casting refractory for vessel linings used for a melted metal is compounded with 30-60wt.% of electrically melted magnesia clinker having a purity of <=98wt.% and a granule diameter of 5-15mm as an aggregate. The amorphous casting refractory can give an extremely dense amorphous refractory cast product having an apparent porosity of <=13%, after dried. When the granule diameter of the used electrically melted magnesia clinker is smaller than 5mm, effective voids contributing to the inhibition of the progress of cracks are sufficiently not generated, and the magnesia clinker is occasionally sintered with surrounding fine powder. When the granule diameter of the electrically melted clinker is larger than 15mm, the generated voids are too large, cause the weakening of tissues, and further cause a problem on the uniform dispersibility of the granules.

Filed: 1988-05-02
Abstract: PURPOSE:To improve the color deviation on the light emitting surface side of the title lens by making the shape of, at least, either one of the incident-side and emission-side curved lens surfaces of each lens unit element asymmetrical with respect to the optical axis of the lens unit element. CONSTITUTION:The lens unit element 15 formed on this lenticular lens sheet has an elliptic-cylindrical surface on the incident-side surface 11 and circular- cylindrical surface which is asymmetrical with respect to the optical axis P of the element 5 on the emission side surface 12. Namely, the emission-side surface 12 is composed of a circular-cylindrical surface 12m formed around a point O1 on the optical axis P and another circular-cylindrical surface 12n formed around another point O2 on the optical axis P and the apex 12a at which the optical axis P intersects the surface 12 lies in the vicinity of the right-side focal point of the ellipse of the incident surface 11. Therefore, optical compensation can be performed against colored light rays made incident to the lens sheet not only to the difference in incident angle, but also to the variation of the refractive index. Thus a colored picture can be observed without color deviation within a prescribed visual angle.
