IPC: G02F1/13
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To realize a highly accurate measurement by forming a transmission preventive structure on the boundary of a glass plate and a liquid crystal on the surface side of a liquid crystal cell of a sample by doping a coloring matter thereby extracting information based on the anchoring energy efficiently. SOLUTION: A sample having a transmission preventive structure in the boundary region of a glass plate 20 and a liquid crystal 22 on the surface side of a liquid crystal cell is employed. The transmission preventive structure is formed by doping the liquid crystal 22 with a coloring matter. When a light of specified wavelength impinges on the glass plate 20 on the surface side at a specified incident angle, a part thereof is reflected on the glass plate 20 on the surface side and another part thereof is passed through the glass plate 20 and reflected on the boundary face of the glass plate 20 and the liquid crystal 22 before leaving the surface of the glass plate 20. The light advancing through the liquid crystal 22 is absorbed by coloring matter.  More specifically, the majority of outgoing light is reflected from liquid crystal molecules subjected to anchoring effect in the vicinity of the interface between the liquid crystal 22 and the glass plate 20 and the anchoring energy of the liquid crystal 22 is measured by receiving the reflected light.

IPC: B41M5/382
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To obtain a high grade and high quality recorded image having high sensitivity without staining, yield a fine transfer receiving property of ink, reproducibility, a fixing property, degradation, and vividness, and have an adaptability for office implements such as writing and printing properties by allowing a receptor layer on the sheet carrier to contain a specific organic pigment as a pigment component. SOLUTION: A high absorptive organic pigment is used as a pigment. The average particle size of the organic pigment is 0.1-10μm in usual and, preferably, 0.1-7μm and, more preferably, 0.1-1.2μm. As the average particle size is 0.1μm or less, an absorptive property of ink becomes short, and as it exceeds 10μm, a transfer property of ink lowers. The organic pigment is preferable to be 100-500ml/100g and, more preferably, to be 100-300ml/100g in its oil absorption quantity. As the oil absorption quantity is 100ml/100g or less, a receiving property of ink becomes short, and as its exceeds 500ml/100g, an adhesive agent is consumed larger than being required affecting bad influences to adhesive forces or paint physical properties. The oil absorption quantity is obtained from the JIS K 5101.
