Title: Display device
Inventor: NAKAJIMA HIRONORI
IPC: G02F1/17
Filed: 1989-04-07
Abstract: PURPOSE:To suppress the decrease of display contrast by absorbing the light of arbitrary intensity other than a light source with a light absorbing filter constituted of a photochromics, etc., responding to its light intensity. CONSTITUTION:Among light 21 emitted from the light source 2 by a light source driving circuit 21, unidirectional light 22 is transmitted by a first light deflecting filter 3; the light 22 is deflected to light 23 in a prescribed direction by a light deflecting element 4; among the rays of light 23, unidirectional light 24 is transmitted by a second light deflecting filter 2. At this time, the light 8 other than the light source is absorbed by the light absorbing filter 6 constituted of the photochromics, etc., responding to its light intensity. Therefore, light 25 can be obtained without apparently decreasing the intensity of the light 24. Thus, the display contrast can be suppressed from decreasing.

Title: Measuring method and apparatus for evaluating uniformity of material structure at molecule level
Inventor: SOUMA HIROTOSHI
IPC: G01N21/65
Filed: 1983-05-20
Abstract: PURPOSE:To establish technology which can measure uniformity of a material at a molecule level, by comparing the spectrum of the second laser light, which is transmitted through a diagnostic sample, with the spectrum of nonlinear light generated by the nonlinear optical effect caused by the first laser light and the second laser light. CONSTITUTION:Laser light b', which is transmitted through a diagnostc sample 3, is observed in the vicinity of frequency omega1 as observed in the ordinary spectroscopic method. The light intensity obtained by a spectroscope 4 is processed by a computer and inverted. The width of a spectrum alpha obtained from the laser light b' indicates ununiform width reflecting the ununiformity of the structure of the sample 3. When the frequency of laser light (b) is changed, nonlinear light (c) is detected as a sharp spectrum beta when the frequency of the laser light becomes omega2=omega1. The width of the spectrum beta indicates the case when molecules are ideally arranged, i.e., the uniform width of the energy of the sample 3. Processing is performed by the computer so that the peak value of the spectrum and the peak value of the spectrum beta become the same, and the spectrums alpha and beta are compared. Then the uniformity of the molecule structure can be quantitatively measured.

Title: Settlement work of marine structure
Inventor: TAKAGI MUTSUMI
IPC: E02B17/00
Filed: 1983-05-20
Abstract: PURPOSE:To easily settle a marine structure by a method in which a closed cellular molding is housed in the inside space of the marine structure, the structure is settled by introducing sea water into the structure while discharging air from the inside space, and the closed cellular molding is removed. CONSTITUTION:A large number of closed cellular moldings 8 are housed in the inside space 7 of a platform 1, whereupon the platform 1 begins to settle. When sea water is introduced from inside and outside through holes 5 and 5' into the space 7, air in the space 7 is discharged through a hatch 6 to the outside. After the completion of the settlement, when a recovery tube 9 is connected to an opening 3 to open the hatch 6, the closed cellular moldings 8 float up in the recovery tube 9 and are discharged to the outside. Since no deformation of the wall of the structure occurs even when the thickness is small, the weight and material cost of the structure can be minimized, load to be required for the settlement can be reduced, and the need for control on compressed air can be eliminated.
