Abstract: PURPOSE:To easily impart a shape and to provide sufficient strength by mixing tricalcium phosphate, acid, polysaccharides and water and curing the resulting mixture. CONSTITUTION:An alpha-type tricalcium phosphate powder, glycolic acid being one of org. acids metabolized in a living body as an acid, dextran actually applied to a living body as a blood substitute preparation from a clinical aspect as one of water soluble polysaccharides, distilled water and granular or powdery hydroxyapatite are mixed as raw materials in a proper mixing ratio to be solidified and cured within several min. In actual mixing, glycolic acid and distilled water are mixed at first and dextran is added to the obtained mixture. The mixing ratio of these components is 6:25: 1 on a wt. basis. When the alpha-type tricalcium phosphate powder is added to the mixed acidic aqueous solution of polysaccharide 2, hydration/coagulation reaction is generated and the mixture becomes a solid cured material. When tricalcium phosphate 3 and hydroxyapatite 1 are mixed at this time to perform reaction, hydroxyapatite 1 is mixed in the coagulated cured material and the cured material becomes harder to be brought to a state hard to absorb.

Title: Information recording medium
Inventor: SAWANO MITSURU
IPC: G11B7/24
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To make it possible to stably maintain an adhesive state without allowing the peeling of a protective layer for a long time by forming a protective layer to the outer peripheral edge of a substrate, which protective layer completely covers a recording layer and a reflection layer. SOLUTION: Pregrooves 12 are formed to the outer peripheral edge of the substrate of the region exclusive of an inner peripheral side substrate region 14. The recording layer 13 is also disposed up to the outer peripheral edge of the substrate. The reflection layer 16 is formed to the outer peripheral edge on the recording layer, i.e., the substrate. Since the reflection layer is formed to the outer peripheral edge of the substrate, there is no need for using a mask and the problems, such as pickup of dust and generation of flaws, do not arise. The protective layer 17 to be formed on the surface of the reflection layer 16 is formed not only the reflection layer 16 but on the end face on the outer peripheral side of the substrate as well. The respective outer peripheral edges of the recording layer and the recording layer are thereby completely covered by the protective layer and, therefore, the peeling from the outer peripheral edge end (more specifically the boundary between the reflection layer and the recording layer or between the substrate and the recording layer) of the reflection layer when the medium is preserved for a long time or used for a long time is prevented.

Filed: 1993-07-16
Abstract: PURPOSE:To obtain a filler which can give a photocurable resin composition having a low viscosity and lowered flow and being curable within a short time by compounding at least two kinds of spherical silica particles having specified particle diameters. CONSTITUTION:The filler prepared by compounding at least two kinds of spherical silica particles having mean particle diameters of 0.25-15mum and maximum particle diameters of 60mum or below is provided.

This filler has the effect of making a photocurable silicone resin curable at a high speed when added thereto an therefore enabling an in-line sealing process. Because the filler is made of quartz and can well transmit UV, it can be cured to a higher depth.

Title: Method for correcting positional deviation between monitor tv camera and density measuring scanner
Inventor: SUZUKI KENJI
IPC: G03B27/72
Filed: 1986-07-29
Abstract: PURPOSE:To eliminate the influence of deviation between the optical axes of both measuring systems by using a positioning sheet to measure the position of an optical mark on a density measuring scanner and that of a monitor CRT and calculating the extent of deviation and performing correction with this extent of positional deviation at the time of designating a principal picture. CONSTITUTION:A positioning sheet 75 is prepared by providing a black optical mark 76 at an approximate center of a transparent film; and a color scanner 35 scans the positioning sheet 75 to measure three-color components of each picture element and generates their respective color signals. These color signals are subjected to digital and logarithmic conversions and are separately written in frame memory parts 45a-45c of RAM 45 with every color. A CPU 44 selects an optional color, for example, red and successively reads out red density of individual picture elements from the frame memory part 45a for red to detect a minimum value. This minimum density value corresponds to the optical mark 76 on the positioning sheet 75, and the address of the memory cell where the minimum value is obtained is written in the RAM 45, and the coordinate of this picture elements is defined as the address of the memory cell. Thus, the positional deviation between two measuring systems is easily corrected.
