IPC: F21V3/04
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a shading sheet for a night light which enables to properly adjust the embedded thickness of a cut sheet constituting a shadow picture by a process, sequentially superposing paper layers to laminate after papermaking by paper layer, and to properly select the contour and the tinting degree of the shadow picture formed by the shading sheet during light floodlight. SOLUTION: A shading sheet can be manufactured with two units of inner paper layer and five units of outer paper layer, thereby enabling mass production and resulting in cost reduction. Cut sheets 3 are placed on an inner paper layer 2 formed beforehand. An outer layer 5 formed similar to the inner layer taking account of the thickness of the inner layer using another mold is placed on the cut sheets for papermaking. The thickness and the pattern of the outer layer 5 can be changed properly, according to the inner layer 2 to form a shadow picture having taste.

Title: Method for selecting and seprating rare metal component from waste fluorescent material
Inventor: SAITO FUMIYOSHI
IPC: H01J9/50
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To further facilitate the separation and recovery of rare metal components from disposed waste fluorescent lamps containing various kinds of rare metals. SOLUTION: Waste fluorescent materials containing rare metal components are subjected to the mechano-chemical treatment of low degree to elude Y and Eu components in a weak acid, and then subjected to the mechano-chemical treatment of high degree to elude La, Ce and Tb components in a weak acid to selectively separate the rare metal components. The degree of the mechano- chemical treatment includes the rotational speed and the treatment time by a ball mill, and in a specific example, the combination of the rotational speed of 700 rpm for two treatment hours by the ball mill is of high degree, while the combination of the rotational speed of 400 rpm for 20 minutes is of low degree. Hydrochloric acid or sulfonic acid of <=1N is suitable for the weak acid.  Since the rare metal components can be extracted by the kind in two parts, the final separation of each component is easy to enable the cyclic use of rare resources.
