18.2: A 2.15 inch QCIF Reflective Color TFT‐LCD with Digital memory on Glass (DMOG)

We have developed a 2.15 inch diagonal, QCIF(144×RGB×176) reflective color TFT-LCD with a new integration technology called DMOG (digital memory on glass), using low-temperature polysilicon (poly-Si) technology. This panel is able to display 4bit × RGB (4096-colors) images and 1bit × RGB (8-colors) still image in power save mode (still mode). We have achieved low power consumption up to 1.3mW in still mode using DMOG.

Radioactive Rare Gas Separation Using a Separation Cell with Two Kinds of Membrane Differing in Gas Permeability Tendency

A separation cell embodying two kinds of membrane—porous and nonporous, i.e. differing in gas permeability—has a separation factor higher than possible with a conventional separation cell with a single kind of membrane. The performance of such separation cells and of cascades constituted thereof are analyzed theoretically and measured experimentally for different conditions of operation, to determine the applicability of the concept to the separation of rare gases from gaseous waste out of nuclear plants. Theoretical considerations indicate that, in a cascade composed of symmetric separation cells, the separation performance can be improved by recycling part of the effluent from a cell back through the same cell (recycling cascade). It is shown that its performance is better than with the arrangement of diverting another effluent several stages upstream. With the recycling cascade, the symmetric separation recycling rate is determined by the depletion separation and enrichment separation factors relevant ...
