Abstract: A system includes a plurality of main body apparatuses and a plurality of controllers removably attachable to the main body apparatuses. The system includes a receiver that receives from a first main body apparatus, first data corresponding to an appearance of a first controller attached to the first main body apparatus, a generator that generates a third image including a first image that depicts an appearance of the main body apparatus and a second image that depicts the appearance of the first controller based on the first data, and a representation control unit that causes second main body apparatus different from the first main body apparatus to show the third image.

Abstract: A bolt axial force monitoring system is disclosed, enabling detection of bolt loosening from a remote location using a simple structure. The system includes a bolt 1 with a display 2 that changes color based on axial force variation. A sensor (e.g., RGB sensor 4) detects this color change. A first communication unit 51 transmits the sensor data, supported by a power supply. At a remote site, a second communication unit 52 receives the data. A determination unit 10 evaluates the change in axial force from the received data, and an output unit such as a display 11 and storage 12 outputs the evaluated information.

Abstract: A method for producing an optical element having a multi-layered antireflection film formed on a synthetic resin substrate, in which the antireflection film formed has good heat resistance, and its heat resistance lowers little with time. At least one high-refraction layer of the multi-layered anti-reflection film contains niobium oxide, zirconium oxide, yttrium oxide, and optionally aluminum oxide. High-refraction layers can be formed within a shorter period of time while not detracting from the good physical properties intrinsic to the layers.

Abstract: A method for producing a composition for vapor deposition comprising sintering a vapor source mixture prepared by mixing vapor sources that contain titanium dioxide and niobium pentoxide. The method is capable of forming a high-refraction layer even in low-temperature vapor deposition on a substrate. An antireflection film is formed having good scratch resistance, good chemical resistance and good heat resistance, of which the heat resistance decreases little with time, that is useful in a variety of optical elements.
