Title: Process to de-compose the radioactivity of metal parts
Inventor: BERTHOLDT HORST-OTTO
IPC: G21F9/00
Filed: 1999-04-23
Granted: 2001-01-11
Abstract: This invention relates to a process for de-composing the radioactivity of metal parts. Thus at first an oxide layer of metal part is removed with a decontaminating solution. It is so designed that afterwards the oxidizing effective material still remaining in the de-contaminating solution is removed, hence a layer of the metal is taken away. Since the radio-nuclides exits only near the surface layer of said metal parts, the remaining metal will be disposed in the usual scrap treatment process.

Title: Reflection type liquid crystal display device using liquid crystal cell for controlling light in scattered or transparent state
Inventor: ONO TOSHIOMI
IPC: G02F1/1334
Filed: 1999-08-30
Granted: 2002-09-01
Abstract: A liquid crystal display device includes a scattering/transparent liquid crystal cell having a liquid crystal layer for controlling incident light in a scattered or transparent state in accordance with an applied electric field, and a reflector having reflecting characteristics to cause light, which has come incident on a front surface of the liquid crystal cell within a range of a viewing angle, to emerge in a direction outside the range of a viewing angle. The reflector causes light, passing through the liquid crystal cell, to emerge in a direction outside the range of a viewing angle with which the liquid crystal cell can be observed. In this liquid crystal cell device, either a scattered or transparent state is selected for light that has passed through the liquid crystal layer upon application of an electric field, and causes this light to come incident on the reflector. According to the characteristic feature of the reflector, light coming incident on the front surface of the liquid crystal cell within the range of a viewing angle emerges in a direction outside the range of a viewing angle, so the light is not observed by the observer. When light passing through the liquid crystal cell is in the scattered state, the scattered light can emerge in directions including one within the range of a viewing angle. When light passing through the liquid crystal cell is set in the scattered state, bright white display can be obtained. When light passing through the liquid crystal cell is transmitted, dark black display can be obtained.
