Title: Pattern displaying method for ornament
Inventor: OGISU YASUHIKO
IPC: G09F3/00
Filed: 1990-02-22
Abstract: PURPOSE:To enable a pattern to be displayed so that it can be seen as two kinds of different metallic brightness in the daytime, while at night light penetrates and the pattern can be seen as if it were floated up, by irradiating a laser beam onto a transparent resin base material in which metallic powdery particles are dispersed, and by changing in quality the metallic powdery particles in the portion irradiated by the laser beam for displaying a pattern. CONSTITUTION:When a laser beam L irradiates a transparent resin base material 2 in which metallic powdery particles 5 are dispersed, the laser beam penetrates through the base material 2 to irradiate the powdery particles 5. As a result, the portion in the powdery particles 5 irradiated by the laser beam L is heated and changed in quality. The state of the surface of the portion changed in quality differs from that of the other portion. Accordingly, when light is incident on an ornament thus formed to hit the powdery particles 5, the angle of reflection of the light differs in the portions. Consequently, the portion changed in quality has brightness different from the other portion, and it can be seen as a pattern 6 when viewed from the outside of the base material 1.

Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To make it possible to use a space effectively by connecting continuously a plurality of face plates, placing a shutter main body flush with the elevation of a ceiling and foldingly housing the main body, placing it in the attic and lifting it up and down with an expansion guide which extends in the floor surface side. SOLUTION: A shutter main body 11 is housed in a flat state in the elevation of a ceiling, thereby forming regularly a ceiling space as a part of a ceiling material. In this case, the shutter main body 11 drops from the ceiling side by extending an expansion guide damper. When the shutter main body 11 reaches a floor surface 10, a space under the ceiling is partitioned. Furthermore, the shutter main body 11 is supported on the expansion guide damper grounded, thereby eliminating the need for a shutter rail which is hitherto required. This construction makes it possible to minimize the connection between building equipment and a building space and use effectively the space by setting up a living room and a corridor and so forth in the space.
