Abstract: An information processing apparatus (1) included in a welding training system includes a transmittance adjuster (14) capable of adjusting a transmittance of a window of a welding helmet in virtual space in multiple grades, and a display controller (17) configured to cause a display of an HMD (2) to display a situation of a welding operation in the virtual space at an illuminance corresponding to the adjusted transmittance. The transmittance adjuster (14) adjusts the transmittance based on a skill level of a trainee determined by a skill level determination unit (13).

Abstract: The present invention provides a reagent comprising an antibody from which part of CH3 or CH2 in the Fc region is deleted.

Abstract: Long carbonaceous moldings and long carbonaceous products as well as methods of production thereof are provided by which carbonaceous products can be obtained without allowing twisting or curving and with less frequent occurrence of cracking etc., even when subjected to heat treatment, and which are excellent in mass productivity. The long carbonaceous moldings have an aspect ratio of 3 to 20 and show fluctuations in the density thereof of not more than 0.05 Mg/m3 throughout the whole moldings.

Abstract: The object of the present invention is to provide: high-reliability and long-life CO2 refrigerant compressor-use bearings that uses bearing materials high in wear resistance and in baking resistance, and; such a compressor, air conditioner, refrigerator, and hot-water supply machine that each employ these bearings.

Abstract: The present invention provides an arthroplasty supporting information calculation method for supporting diagnoses of a patient with knee disordered and total joint replacement to a total knee component, and an arthroplasty supporting information calculation program, and an arthroplasty supporting information calculation system. In an arthroplasty supporting terminal of the present invention, photographed X-ray images are acquired using X-ray irradiation mechanisms and a dedicated cassette base, Approximate three-dimensional data of a patient's bones is then created by transforming a display image of three-dimensional data of CT of the patient and/or sample bones to match the X-ray image in which the patient's bones are photographed. Three-dimensional coordinate values are then determined for this approximate three-dimensional data of the patient's bones. From these three-dimensional coordinate values, parameters are determined for evaluating positional relationships between at least two bones.

Abstract: An oxidation resistant carbon material including a composite material is provided. The composite material is obtained by impregnating a carbon material with a boron oxide and/or a hydrate compound thereof, and baking such carbon material under pressure by inert gas at a temperature of not lower than 1500.degree. C.

Abstract: There is provided according to the invention a method for producing a composite material mainly composed of a carbon and boron comprising the steps of impregnating a carbon material with a boron oxide and/or a hydrate compound thereof, and baking such carbon material under pressure by inert gas at a temperature of not lower than 1500.degree. C. A neutron absorbent and an oxidation resistant carbon material both including the composite material are also provided.

Abstract: There is provided a method for producing a carbon material coated with carbon film comprising the steps of dissolving an aromatic polyamide imide resin in an organic solvent to obtain a solution, applying this solution to a carbon material or impregnating the carbon material with the solution, curing the material at 300 to 400%, and carbonizing and/or graphitizing the material by baking under non-oxidizing atmosphere. There is also provided a carbon material coated with an amorphous carbon film which is a product of thermal decomposition of aromatic polyamide imide.
