IPC: G02B5/28
Filed: 1996-05-07
Abstract: PURPOSE: To suppress the occurrence of color lines, color stripes, brightness and darkness stripes, and the like by laminating high refractive index layers and low refractive index layers alternately on the surface of a reflector so as to constitute a light interference film, and thickening the film thickness thereof as the incident angle of the light from a light source becomes large. CONSTITUTION: High ref reactive index layers and low refractive index layers are alternately laminated on the inside surface of the curved base body 3 of a reflector so as to constitute a light interference film 4. In the light interference film 4, the film thickness thereof is made to be thick as the incident angle of the light from a light source 1 becomes large, that is, as approaching to the opening portion of the reflector. Thereby, the wavelength area of the penetrating-in or reflecting-on light becomes uniform on the whole surface of the light interference film 4 so that the occurrence of color lines, color stripes, and brightness and darkness stripes are suppressed.

Title: Automatic plotting machine
Inventor: TAKEUCHI SHINICHI
IPC: B43L13/20
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To realize the proper drawing of figures on a small paper by holding the paper with a scale through magnets arranged on the scale by comprising a pen arm, which is shiftable to XY-directions to the surface of a paper, and the scale, which indicates drawing positions, and, at the same time, arranging the magnets on the scale. SOLUTION: When a small paper H is plotted, the paper is placed on a steel desk so as to put a scale 16 on the paper H by seating a main body 11 onto the desk. Since magnets 21 are provided on the scale 16, the scale 16 holds the paper 11 down by means of the attracting force caused between each magnet 21 and the desk. Thus, the paper H is prevented from being moved through the movements of a pen arm 30 is XY-directions, resulting in realizing the proper plotting even on the small paper H. Further, since the magnets 21 are provided at the four corners of the scale 16, the paper H can be surely held with the scale 16. In addition, the stronger holder-down of the paper H can be realized by providing magnets on the under surface of the main body 11.
