Title: Method of cutting blade inspection
Inventor: IMATA TSUTOMU
IPC: B23Q17/20
Filed: 1978-02-17
Abstract: PURPOSE:To detect automatically a damage to a blade, by electrically treating the condition of light reflection on a cut surface. CONSTITUTION:Under a normal cut condition, a cutting line is normally formed and this cutting line becomes a shadow, and the light reflected on the projection surface at this time becomes weak. Consequently, the electric signal level obtained by means of magnifying glass 7, hole 10 on slit plate 6 and photo-diode array 8 becomes low. For this reason, the rotation drive circuit of blade 3 maintains normal operation and cutting operation is continued. In case blade 3 is bent or partly damaged, no cutting line is formed on the surface of semiconductor wafer 2, and hence, almost all of the projection lights from lamps 4 and 5 are reflected and the electric signal exceeds a certain fixed level. As a result, the operation of the rotation drive circuit of blade 3 stops, the rotation of blade 3 stops and any damage to blade 3 is detected.

Abstract: PURPOSE:To make the beam diameter conversion system short and also reduce its size by decreasing the diameter of a laser beam by a 1st convex lens and a concave lens and further varying the diameter to a desired value by a 2nd concave lens and a convex lens. CONSTITUTION:The laser beam from a laser light source 1 is converged by the 1st convex lens 2 and the converged luminous flux is collimated by the 1st concave lens 11 into parallel light, which is made incident on an image data AOM4 where the light is modulated with image data.

Abstract: PURPOSE:To enable a person who has fingers without characteristic fingerprint or fingers hard to fingerprint identification due to an injury, etc. to register by another finger, and enable the person to improve ability of individual identification by providing a characteristic parameter extracting section and a characteristic parameter memory. CONSTITUTION:In fingerprint registration, video signals inputted by a person who registers his fingerprints through fingerprint preparing sections 1-5 are A/D converted in a picture processing section 7 and inputted to a characteristic parameter extracting section 8 as data. The section 8 converts the data to characteristic parameter of the registered person and outputs.

Title: Method for detecting demyelinating disease
Inventor: KIYOUGASHIMA MAMORU
IPC: G01N33/53
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To early diagnose demyelinating disease such as multiple sclerosis, acute polynesic encephalomyelitis, etc., by measuring a level of a thrombin- antithrombin III complex in a body humor. SOLUTION: A level of a thrombin-antithrombin III complex (TAT) in a test body such as blood or the like rises prior to the manifestation of a clinical symptom of demyelinating disease, and therefore the demyelinating disease can be diagnosed early by measuring the level of the TAT in the test body. A usable body humor is blood, blood plasma and blood serum fractioned from the blood, cerebrospinal fluid, etc., but not limited to these. The level of the TAT in blood to be measured can be measured in place of a level of thrombin quickly disappearing in blood and is usable as an index of thrombin formation activity, i.e., blood coagulation activity, thrombus formation tendency or the like. Although a measurement method for the TAT is not particularly specified, generally, an immunological measurement method utilizing an antigen antibody reaction is preferred.
