IPC: G16H10/60
Filed: 1993-09-10
Abstract: PURPOSE:To decide easily and quickly on whether correct or wrong with respect to a measured value on the medical information system and to improve efficiency in diagnosing patients by judging whether the measured value is significant or not from the correlation coefficient between the measured value and time and, when judged not significant, whether to reject a hypothesis or not, upon operating a t-test. CONSTITUTION:In the step Q1, the correlation coefficient between a measured value and time is found and in the step Q2, a judgment whether the measured value is significant or not is made. When the measured value is judged to be significant, the measurement is decided to be made correctly (step Q6). On the other hand, when the value is judged to be not significant, a t-test is operated (step Q3) to judge whether to reject a hypothesis or not (step Q4). The t-test is called a reject test, by which a decision is made whether to reject a measured value, if any, which is alone far apart from the other measured values, or not. Through such process, a decision on whether correct or wrong with respect to a measured value on the medical information system is made extremely easily and quickly and efficiency in diagnosing patients is improved.

IPC: G02F1/13357
Filed: 1993-09-10
Abstract: PURPOSE:To provide a polarization converting optical system constituted so that the luminance of a picture projected by a projection type liquid crystal display device is improved. CONSTITUTION:Aspherical reflecting mirrors 2 are adjacently arranged to two polarizing beam splitters(PBS) 1 whose polarization and separation surfaces are mutually orthogonally crossed. When light is made incident on the PBS 1 from a light source 4, (p) polarized light is transmitted and (s) polarized light is reflected. The aspherical surfaces of the mirrors 2 are formed so that the reflected light out of the (s) polarized light reflected, whose optical path after reflection on the mirror 2 is at a position near to the PBS 1, becomes almost in parallel with the transmitted light of the PBS 1 and the reflected light whose optical path is at a position distant from the PBS 1 becomes focusing light with respect to the transmitted light of the PBS 1. By such constitution, a focusing beam by the polarized light is obtained with respect to the reflected light among luminous fluxes at the central part of the light source 4 on the polarization and separation surfaces at the position near the PBS 1 without allowing the PBS 1 to obstruct the optical path.

Title: Method for ultrasonic flaw detection of hexagon socket head bolt
Inventor: SUYAMA SHOJI
IPC: G01N29/04
Filed: 1985-11-08
Abstract: PURPOSE:To attain to enhance flaw detection capacity, by allowing ultrasonic beam to be incident on the doughnut like elongated part of the flat part of the head part of a hexagon head bolt while converging the ultrasonic beam. CONSTITUTION:A hexagon socket head bolt 11 is set in water 16 and a converging type probe 18 having an acoustic lens 17 mounted thereon is arranged in the vicinity of the surface of the water. The probe 18 is arranged so that the converging range of the ultrasonic beam 19 emitted therefrom is set to the plane part 15 of the head part 12 of the bolt 11. Because the bolt head part 12 has an elongated doughnut shape, the shape of said beam is set so as not to exceed the width of said head part 12. Next, the probe 18 is arranged so as to be inclined with respect to the plane part 15 of the bolt 11 and a longitudinal wave is incident on the probe 18 from underwater and a transversal wave generated by mode conversion is allowed to be incident to the bolt head part 12 and the incident transversal wave is once reflected from the outer peripheral surface of the bolt head part 12 to be allowed to reach a neck throat part 21. If a flaw is present in the throat part 21, the reflected wave therefrom propagates through a reverse route to be received as a flaw echo by the probe 18. by By this method, high flaw detection capacity is obtained.
