Abstract:
There is provided an optical system for measurement of optical constant capable of measuring the absolute reflectance and the absolute transmittance for determining the optical constant of a substance with excellent accuracy without replacing the optical system during the measurement by using a different system for measuring the absolute reflectance and the absolute transmittance of the sample, comprising an incoming side beam switching mirror for selectively switching the direction of the light from a light source to a first or second converged light reflecting means side, first and second converged light reflecting means for projecting the light from the beam switching mirror so as to be converged in an intersecting manner at the position of a sample holder, the sample bolder capable of selectively positioning a sample fitting hole or a through hole at the converging position by the converged light reflecting means by advancing/retracting the sample fitting hole or the through hole, first and second received light reflecting means which are disposed on the optical path of the light reflected by or transmitted through a sample set in the sample fitting hole on the sample holder or the through hole, and direct the light toward a single exiting side beam switching mirror, and the exiting side beam switching mirror capable of switching the direction of the light projected via the received light reflecting means toward a single detector, and the absolute reflectance and the absolute transmittance for the face side incidence and the back side incidence of the sample.

Abstract:
A method for producing a lactam by using an organic solvent as a substrate solution, which makes it possible to introduce a high-concentration oxime into flowing high-temperature and high-pressure water, thereby allowing the high-concentration lactam to be synthesized with a high efficiency. With this method, the lactam is continuously synthesized at a high rate from the oxime under high-temperature and high-pressure water mixture conditions within a temperature range of no less than 250null C. and a pressure range of no less than 15 MPa.

A method for inspecting multilayer masks to detect any defects includes illuminating a pixel region on a mask to be inspected, using illuminating light having a peak wavelength that is close to that of light reflected by the mask. The illuminating light specularly reflected by the mask is blocked Scattered reflected illuminating light is collected and used to form an enlarged image. An image detector having a large plurality of pixels is used to observe the enlarged image to detect whether there are defects on the mask. The method is implemented using an mask inspection apparatus including a plasma light source for generating radiant rays, an illuminating light collecting optical system that collects radiated light from the light source for enlarged image formation illumination of a subject inspection region, a Schwarzschild optical system including convex and concave mirrors for collecting scattered light from the subject inspection region and forming an enlarged image of the inspection region, an image detector having a large plurality of pixels for recording the enlarged image that is obtained, and an analyzer that analyzes the images obtained to determine whether there is a defect.
Abstract:
A semiconductor device is manufactured using a SiC substrate. On a semiconductor region a region formed of SiC having an (11-20) face orientation is formed. A gate insulation layer is a gate oxidation layer. The surface of the semiconductor region is cleaned, and the gate insulation layer is formed in an atmosphere containing hydrogen or water vapor After the gate insulation layer has been formed, the substrate is heat-treated in an atmosphere containing hydrogen or water vapor. This reduces the interface-trap and the semiconductor region.
Abstract:
The polygon-type semiconductor detector for use in a high-speed X-ray CT according to the present invention enables a high resolution, and allows the time and cost for manufacturing to be significantly reduced, by virtue of the detection pixel group thereof having mutually homogeneous characteristics. First, X-ray modules are each constructed by arranging a plurality of X-ray detection pixels (4) formed by means of photolithography in a line on a single planar semiconductor substrate constituted of CdTe. Then, by polygonally arranging a plurality of these X-ray modules on the circumference of a measuring section around a measuring area, this polygon-type semiconductor detector is formed. Thereby, when a multiphase fluid having mutually different densities flows in the measuring area (10), this polygon-type semiconductor detector can acquire the projection data of internal density distributions at a high speed.

This invention provides a method of suspending and resuming software execution that enables a software execution state to be saved and, as required, transferred to another computer and execution resumed. This is done by including a step of running a second computer program in a real or virtual computer system that emulates functions of a real or virtual computer configured using a first computer program that can save a snapshot of a computer system operation state at a specified time; a step of saving a snapshot of the virtual computer system, or a transmission step; a step of loading the saved or transmitted snapshot on a computer system that substantially corresponds to the real or virtual computer system; and a step of starting operations on a computer system that substantially corresponds to the real or virtual computer system.

A thermometer calibration method and fixed-point temperature realizing apparatus uses a fixed-point cell including a crucible of carbon and a fixed-point material enclosed in the crucible. The fixed-point material is a eutectic structure of carbide and carbon. The fixed-point cell is placed in a furnace for increasing and decreasing the environmental temperature of the cell. A thermometer to be calibrated is used to measure temperature variations in the cell and calibrated based on the temperature variations thus measured.
