IPC: G02B6/35
Filed: 1980-03-31
Abstract: PURPOSE:To improve reproducibility of optical path changing by rotating and moving a spherical mirror or a cylindrical mirror surface and putting the same into and out from the optical path. CONSTITUTION:This switch is so constituted that a spherical mirror 12 is rotated and moved around a rotating shaft 18 and is thereby put into and out from the optical path.

IPC: C11D3/04
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To easily remove stains on the surface of sanitary earthenware by running water or the like by adding an Na component in the glaze layer of the sanitary earthenware. SOLUTION: Main adhering stains brought to the surface of sanitary earthenware are oily stains containing a carboxyl end group and water scales. When the oily stains containing a carboxyl end group are brought to the surface of the sanitary earthenware, if an Na component exists, the Na component adsorbs preferentially the oil stains due to the substitution reaction, improving the affinity of the stains to water, and if the stains are monomeric, the stains become water soluble (saponify), increasing the affinity of the stains to water than the surface of the earthenware and making the stains to be removed by flushing. Furthermore, the Na component must represent 2.6 wt.% or more, preferably 3 wt.% or more of all metal components in the glaze layer in terms of oxides, thereby improving significantly the self-cleaning function against adhering stains.
