Filed: 1981-01-16
Abstract: PURPOSE: To obtain a filter suited to the portrait photography, by forming a filter that satisfies a specific condition and vignetting only the green light region in the wavelength region of visible rays.  
     CONSTITUTION: The phase parts 11 are distributed at random on a filter substrate to cause the difference of phase to the wave surface that transmitted through a filter. A phase difference δ is caused between the wave surface that transmitted through the part 11 and that transmitted through other part 12. The filter is formed so as to satisfy equationIby the difference δ, where m is an integer and λ 0  is a prescribed wavelength of a green light region. Thus the green color region is selectively vignetted to assure the sharp formation of images for the light of the ambient blue and red color regions. Accordingly a soft tone is given to the human skin, and a sharp tone is given to the clothing, etc. In such way, a filter suited to the portrait photography is obtained.

Title: Centrifugal compressor
Inventor: NAKAGAWA KOUJI
IPC: F04D29/46
Filed: 1982-01-20
Abstract: PURPOSE:To prevent occurrence of surging at the time of low flow-rate operation of a centrifugal compressor, by arranging annular cascades in two stages so that fluid is passed through an inner cascade or both of the inner and the outer cascades. CONSTITUTION:Since an inner, annular cascade 20 is designed to suit the low flow-rate operation of a centrifugal compressor, it is operated normally as a diffuser when the flow rate of fluid is low. On the other hand, an outer, annular cascade 23 does not always operate normally as a diffuser under the state that the flow rate of fluid is low. However, since the inner cascade 20 always operates normally as a diffuser, there is no fear of the compressor to cause surging.
