Inventor: MIMURA SHOJI
IPC: C30B15/00
Filed: 1990-03-23
Abstract: PURPOSE:To obtain single crystal which is free from cracks and little in coloring and high in transparence by specifying the purity of titanium dioxide and barium carbonate which is a starting raw material and specifying the concn. of oxygen in the atmosphere for growing crystal. CONSTITUTION:The mixed powder of titanium dioxide having >=99.99% purity and barium carbonate having >=99.95% purity is utilized as a starting raw material. This mixed powder is heated at 1300-1450 deg.C and melted. Single crystal is grown on the surface of seed crystal of barium titanate by bringing this seed crystal into contact with this melt and lowering the temp. of the melt. In this case, the concn. of oxygen in the atmosphere for growing single crystal is regulated to >=20.1vol.%. When the purity of titanium dioxide or barium carbonate is lower than the above-mentioned value, the obtained barium titanate single crystal shows deep brown by the impurities in the raw materials. On the other hand, when the concn. of oxygen in the atmosphere for growing crystal is lower than the value, a crack is generated in crystal.

Title: Multicolor transparent soap and production thereof
Inventor: HARA MASAYUKI
IPC: C11D17/00
Filed: 1988-03-28
Abstract: PURPOSE:To obtain a multicolor transparent soap having a laminate structure of clearly colored layers and a beautiful appearance, by separating a transparent soap stock in a molten state into a plurality of portions, coloring the individual portions in different colors and providing them with different specific gravities, followed by simultaneous cooling and solidification. CONSTITUTION:After the completion of saponification, a transparent soap stock in a molten state is separated into a plurality of portions and the individual portions are colored in different colors. At the same time, the compsn. of each of the individual portions is changed so as to have a different specific gravity. Then, these portions are simultaneously cooled and solidified in the same container to prepare the desired soap. In the production of the transparent soap, the specific gravities of the individual stock portions are rendered different so that layers can be formed by simultaneous cooling in the same container. As a result, the whole of the individual layers can be dried under identical conditions. Accordingly, it is possible to prevent a gap from being formed at the boundary lines of the layers and to clarify color boundaries. Moreover, the transparent soap is free from a drawback such that peeling occurs at the boundary faces during use.

The passbook A is correctively bent a projecting curve to a recessed curve in a backward direction by the action of reversely bent protrusions 21,22 and rubber rollers 12, 12. Consequently, the resistance due to separation friction generating on the inner paper (a) increases. If the drive rollers 5, 7 are driven by rotation in an arrow direction, the first inner sheet (a) of the passbook A is separated from the second inner sheet by the rubber roller 12.
