A new solution for splay‐to‐bend transition in OCB mode with a twisted area

Abstract— Quick, stable transition from splay‐to‐bend alignment in optically compensated bend (OCB) mode is crucial for practical use. This has been achieved by surface treating part of a pixel with a chiral dopant to induce a twist alignment while controlling the twist direction. The effectiveness of this new method was confirmed in a prototype TFT‐LCD panel.     

The spontaneous formation of a J-like aggregate in Langmuir-Blodgett films of a squarylium dye

The physical properties of chalcogenide-containing squarylium (SQ) dyes with long alkyl chains were examined. The SQ dyes were deposited as Y-type films. The SQ dye of a 6-methylselenazole derivative spontaneously forms a J-like aggregate in Langmuir-Blodgett films at ambient conditions.     

Inelastic behaviour of steel under plasticity-creep interaction condition: An interim report of the Bench Mark project by the subcommittee on inelastic analysis and life prediction of high temperature materials, JSMS

Some of the interim results of the Bench Mark Project by the Subcommittee on the Inelastic Analysis and Life Prediction of High Temperature Materials, JSMS, is presented. The purpose of the present bench mark study is to review and evaluate the inelastic constitutive models relevant to material response under the plasticity-creep interaction.By specifying normalized and tempered steel at 600°C, sixteen bench mark problems of four categories are first established: (I) tensile stress-strain relations and creep curves, (II) material response under mixed modes of plastic and creep loading, (III) ratcheting and deformation under program loads, and (IV) cyclic deformation behaviour under the combination of different strain rates. Then, the outline of seventeen inelastic constitutive models of nine types discussed in this project is presented. Finally, the interim results of these bench mark tests are compared with the corresponding predictions of the constitutive models to evaluate their accuracy in simulating the actual behaviour of the material.     

Evaluation of the Parallel Conductor Theory for Measuring Human Limb Blood Flow by Electrical Admittance Plethysmography

We devised a compensation technique that measures the admittance change of a limb submerged in an electrolyte solution in a cylinder. Using this technique, we evaluated the accuracy of admittance plethysmography and the validity of the parallel-conductor model on which the theory of blood flow measurement by electrical admittance (or impedance) plethysmography is based. From a theoretical point of view, if a limb is regarded as a parallel-conductor model, the admittance change due to blood pooling following venous occlusion should disappear when the resistivity of the solution is equal to that of the blood.     

Synthesis and properties of polymeric latex particles and their conjugates with human immunoglobulin G

Polymeric latex particles of uniform size in the range of 750 to 10 000 Å in diameter were prepared by emulsion copolymerization of methyl methacrylate, methacrylic acid, 2-hydroxyethyl methacrylate and ethylene glycol dimethacrylate, using sodium dodecylbenzene sulphonate as an emulsifier and ammonium persulphate as an initiator. With a fixed composition of monomers the carboxyl groups on the latex particles ranged from 5 × 10³ to 180 × 10³ per particle, but the average number per unit surface area remained within a limited variation. Human immunoglobulin G (IgG) was covalently bonded to the latex particles by either the carbodiimide or the cyanogen bromide method, taking advantage of carboxyl and hydroxyl groups, respectively. The resulting conjugates exhibited a specific agglutination with rabbit anti-human IgG and sera from rheumatoid arthritis (RA) patients. The immunolatex particles were found to be superior to those derived from nylon-6, which had been used in our previous work, and are expected to offer useful means in various immunological studies.
