Filed: 1994-08-02
Abstract: PURPOSE: To display a transparent medium in transmitted light with sufficient contrast by arranging phase difference generating elements, which image the transparent medium as a phase body having amplitude contrast, in two observation optical paths. CONSTITUTION: Power switching means 2a and 2b are arranged behind a common objective 1. On a secondary light source image plane, the phase difference generating elements 4a and 4b shown in outline are fixed and arranged.

IPC: E06B9/26
Filed: 1994-08-24
Abstract: PURPOSE: To improve an indoor environment by arranging a plurality of openable louvers made of magnetic shielding material opposite to a window, closing the window with the louvers held close together by a magnet provided on a sash frame, and allowing daylight in through the slits of the louvers. CONSTITUTION: Louvers 5 overlap one another when closed.
