IPC: D03D15/00
Filed: 1990-07-28
Abstract: PURPOSE:To obtain a multi-colored weft woven total KASURI (cloth with splashed pattern) fabric having diamond-design KASURI mark by preparing a color master- drawing having a size nearly equal to the product to be woven, extending the drawing in longitudinal direction to form a color master-drawing for the manufacture of a printing stencil, printing wefts wound on a thin plate and weaving the yarn after matching the KASURI pattern. CONSTITUTION:A color master-drawing having a size nearly equal to the product to be woven and having a colored complete pattern is manufactured and extended exclusively in longitudinal direction to obtain a longitudinally extended color master- drawing. Printing stencils (color master-drawing for producing the stencils) for individual colors are produced from the longitudinally extended color master-drawing. A printing stencil for a crossed warp and weft KASURI such as diamond-design or cross-design KASURI is also produced by the similar manner. Wefts wound on a thin plate are printed by a conventional printing technique using the plural number of the printing stencils. The objective multi-colored total KASURI fabric having diamond-design KASURI mark can be produced by weaving the KASURI wefts, the KASURI wefts for crossed KASURI and warps after matching the KASURI pattern.

IPC: F24F5/00
Filed: 1994-08-24
Abstract: PURPOSE: To obtain a separate type air conditioner being excellent in an operation efficiency and durability and capable of reducing/moisture under the floor of a house. CONSTITUTION: In a separate type air conditioner 1 separated into an indoor machine 3 and an outdoor machine 5, the outdoor machine 5 is disposed in a space 26 under the floor of a house.

Abstract: PURPOSE:To eliminate measuring errors associated with spectroscopic measurement starting position accuracy, by making light to be measured and a source light for correction alternately into a spectrosope to measure the source light for correction in the course of a single continuous measurement of spectrum. CONSTITUTION:A source light light 32 for correction and a light 31 to be measured are recorded from the same spectroscopic measurement starting position.

When the number of waves swept with a spectroscope reaches 43 (515cm<-1>), the Ne tube 36 is removed and the light 31 being measured is introduced into the spectroscope. When the wave number is corrected using the reference of the spectrum with the wavelength corresponding to a Raman's shift 513cm<-1> among lights emitted from the Ne tube 36, the accuracy of DELTAlambda 0.1cm<-1> is obtained in the relative wavelength of the light 31 being measured from the spectrum peak 44 of the Si (100) face and thus the wavelength lambda2 of the light being measured is found at a high accuracy from lambda2=lambda1+DELTAlambda.
