Title: Optical encoder
Inventor: NAKAYAMA HIROSHI
IPC: G01D5/30
Filed: 1992-03-04
Abstract: PURPOSE:To make a compact encoder without the need of strict alignment of optical elements by using a reflecting-type code plate and arranging a diffusion surface and a detecting surface of a light source on the same plane. CONSTITUTION:A diffusing plate 2 turns the light from a light emitting source 1 to diffused light. A window part of a mask 3 assumes the shape obtained by folding the half cycle of the sine wave or the waveform approximate to the sine wave up and down. A code plate 4' is a reflecting type, in which reflecting parts 4a' for regularly reflecting the light and non-reflecting parts 4b' for transmitting or absorbing the light are arranged alternately. A photodetecting array 5 is set on the same plane S as the diffusing plate 2. The diffused light spatially weighted by the mask 3 is reflected at the reflecting parts 4a' and therefore illuminates the photodetecting array 5. As a result, the illuminance distribution of the sine wave is generated on the photodetecting surface. The rotation or displacement of the code plate 4' is measured by detecting the phase of the illuminance distribution. The distance between the code plate 4' and the diffusion plate 2 is equal to that of the code plate 4' and the photodetecting array 5. Therefore, it is not necessary to align the elements.

Title: Formation of inorganic coating film
Inventor: NAKADATE SOU
IPC: B05D7/24
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To form an inorg. coating film with narrow surface creaks by applying an aq. soln. of an water-soluble alkali metal silicate on the surface of a substrate, drying the soln., bringing the dried soln. into contact with a dealkalizing soln., washing the substrate with water and drying the substrate. SOLUTION: An aq. soln. of an ammonium salt, a phosphate or an oxalate is used as a dealkalizing soln., and the soln. is bright into contact with a first treating soln. at pH3.5 to 5.5 and then with a second treating soln,. at pH6 to 8.5. Accordingly, since the substrate is treated with the first treating soln. at relatively low pH3.5 to 5.5 and then treated with the second treating soln. at relatively high pH6 to 8.5, the elution of the alkali metal ion in a coating material is promoted, and further the width of the crack is decreased. The generation of cracks which lower contamination resistance is suppressed, the strength of even a substrate low in acid resistance is not lowered, and a good inorg. coating film is formed in a short time.

Abstract: PURPOSE:To eliminate dispersion of aperture diameters or the like, and improve fringe contour performance, even if a metal material plate for shadow mask having surface irregularity, by forming a covering coat suppressing irregular reflection on the metal material plate surface for shadow mask. CONSTITUTION:On the surface of a degreased metal material plate 1 for a shadow mask a covering coat 6 suppressing irregular reflection and a resist applied coat 2 are formed, and a master pattern 3 is placed thereon. Thereby, even if ultraviolet rays or near ultraviolet rays 4 are radiated from above the pattern 3 so as to expose, no irregular reflection is allowed, since the coat 6 is formed so as to suppress the irregular reflection of the rays 4 irradiating to the irregularity 8 of the plate 1.
