Title: Information recording medium, optical disk and reproducing device
Inventor: ITO TAMOTSU
IPC: G11B7/24012
Filed: 1994-04-01
Abstract: PURPOSE:To form a visual pattern, of which regular shape is lost when it is copied, on a CD-ROM. CONSTITUTION:An area for forming a character/graphic pattern is provided on a CD-ROM 4. The character/graphic pattern 14 is formed by recording data for generating two kinds of pit patterns making a visual difference between them in average reflectance on the CD-ROM 4 in the internal part and the external part of the textural/graphic pattern respectively. By this method, unless a copy version CD-ROM is produced by copying the original version CD-ROM with extremely high accuracy, the character/graphic pattern is out of shape by deviating the disposition of the pit patterns from the original version, thus, its vidual recognition is impossible.

Filed: 1985-03-29
Abstract: PURPOSE:To easily confirm an erasing extent on an original, by displaying that whether the inside or outside of a designated erasing extent is to be erased by switching by using a lighting or flickering spot light source. CONSTITUTION:By operating operation keys 30a-30d, a spot light is moved to points S1 and S2 on an original G and, by depressing erasing extent designating keys 30f and 30g, a rectangular area with the points S1 and S2 at its diagonal points or the outside of the rectangular area is designated as an erasing extent. When a check key 30h is designated, the spot light is turned on and moves from the coordinate position S1 to the point S1 through coordinates (x1, y2), S2, and (x2, y1) and indicates that the inside of the rectangular area is the erasing extent, if the inside of the desinated coordinates is the erasing extent.

Title: Predicting method of fatigue damage
Inventor: AOKI HISAO
IPC: G01M99/00
Filed: 1984-04-03
Abstract: PURPOSE:To predict the fatigue damage of a structure which has excellent precision and detection performance by fitting a prediction piece with a cut to the structure, and detecting its cracking. CONSTITUTION:The prediction piece 2 made of the same material with the structure 1 is fitted to a fatigue cracking dangerous position of the structure 1. Fatigue cracking starts at the position of the cut 3 earlier in the piece with the cut 3 than in the structure 1. The cracking starting at the cut 3 stops at a hole 4. The hole 4 has a smooth internal-diameter surface, so notch effect is small and the growth of the cracking to the structure body 1 is impeded. For the purpose, the generation of cracking in the piece 2 is detected to know the fatigue damage of the structure 1 before harmful cracking is generated in the structure 1.

Title: Optical recording medium
Inventor: KAWAKAMI HARUO
IPC: G11B7/24
Filed: 1988-03-18
Abstract: PURPOSE:To lower light power for recording and erasing and to improve the life of the above recording medium by providing a light absorptive layer consisting of specific compds. and a diffusion preventive layer between a medium layer and the light absorptive layer. CONSTITUTION:This optical recording medium is constituted by successively laminating a protective layer 2, the medium layer 3, the diffusion preventive layer 7, the light absorptive layer 6, and a protective film 4 on a substrate 1. The light absorptive layer 6 consists of at least one kind of PbSe and PbTe. Polycarbonate is unsable as the substrate 1, SiO2 as the protective layer 2, InTe as the medium layer 3, AlN as the diffusion preventive layer 7 and SiO2 as the protective layer 4. The initial state is formed by projecting laser light to the medium layer 3 to crystallize said layer. The absorption coefft. of the PbSe or PbTe of the absorptive layer 6 is larger than the absorption coefft. of the InTe of the medium layer 3 and has a high m.p. The light energy is thus efficiently absorbed by the absorptive layer 6 and is converted to heat which is transmitted to the medium layer 3.

A column is cut out from the central part of the obtained quartz glass lump to produce a cylindrical, silica matrix containing the bubbles of the oxygen. Subsequently, a highly pure transparent synthetic quartz glass optical member is set in the matrix containing the oxygen bubbles and treated with heat. The oxygen can thereby be supplied to the synthetic quartz glass optical member even under the atmosphere of an inert gas to efficiently modify the synthetic quartz glass optical member.
