Title: Reflection type screen and its manufacture
Inventor: NAKAJIMA MASAO
IPC: G03B21/60
Filed: 1990-01-12
Abstract: PURPOSE:To obtain a screen having the wide half-angle (angle of visibility) by providing an optical reflection layer formed of an ink layer containing pearl pigment as filler on a plastic film or a sheet and also forming a transparent beads layer having light converging ability on the surface of the reflection layer. CONSTITUTION:The ink layer containing pearl pigment scales which are obtained by coating mica with titanium dioxide as the filler is disposed on the plastic film or the sheet as the optical reflection layer. And a transfer sheet provided with the transparent beads layer is heated and is made to press- bond on the base material of the ink layer through an adhesive layer so as to form the transparent beads layer on the surface of the optical reflection layer. By coping with the troubles such as the insufficiently of the half-angle of a screen having the optical reflection layer formed of only the pearl pigment ink and the insufficiency of recurrence in such a way, and also by performing beads processing, the screen having the wide half-angle can be obtained.

Abstract: PURPOSE:To display the signal of an object so as to be capable of easily discriminating the same from other signals, by a method wherein a timewise phase difference signal is converted to a phase difference signal to frequency and discriminating the phase difference signal to frequency equal to or less than predetermined frequency and equal to or more than a predetermined level from the other signal as the signal of the object. CONSTITUTION:The signal received by a first receiver 1 and the signal received by a second receiver 2 are sent to a correlation device 3 and receive correlation processing to calculate a phase difference signal phi. This phase difference signal phi is the function of the incident angle phi of a plane wave and sent to a memory 4 to be temporarily stored therein as a time series signal. In the memory 4, a time width T is made constant while a delivery range is timewise shifted by T and repeatedly sent to a Fourier transformer 5 which in turn performs frequency analysis at every time series signal of the time width T. The frequency spectrum 105 of the output of the Fourier transformer 5 is sent, to a threshold value judge device 6. The threshold value judging device 6 judges whether the sent signal frequency spectrum has a value equal to or less than certain frequency and equal to or more than a predetermined level and outputs said spectrum.
