Abstract: Exemplary communication system 1 includes game devices 10, communication terminals 20, and game support server 30. Game devices 10 enable users to perform a multi-play activity. Each of communication terminals 20 runs an application associated with corresponding game device 10. Game support server 30 divides communication terminals 20 into separate communication groups in accordance with a situation of the multi-play activity performed by game devices 10 so that communication terminals 20 belonging to a same communication group can communicate with each other.

Abstract: A radiation thermometer 100 includes two infrared detectors 1 and 1? and a temperature calculator 2. The infrared detectors 1 and 1? each have a predetermined measurement visual field and detect the amount of infrared rays incident from the measurement visual field. The temperature calculator 2 calculates the temperature of a measurement target region Xa based on the amounts of infrared rays detected by the respective infrared detectors 1 and 1?. The measurement target region Xa is included in the measurement visual fields of the respective infrared detectors 1 and 1?, and the sizes of the respective measurement visual fields are set to be different frm each other with respect to the measurement target region Xa.

Abstract: In order that a temperature of a measurement object whose non-transmission wavelength range is narrow, such as isopropyl alcohol can be measured highly accurately without increasing the size of a radiation thermometer, the radiation thermometer includes an infrared detection element to detect infrared ray emitted from the measurement object. The radiation thermometer is designed to measure the temperature of the measurement object on the basis of intensity of infrared ray detected by the infrared detection element. The radiation thermometer further includes a filter group made up of a plurality of infrared filters arranged on an optical path of infrared ray introduced into the infrared detection element. The filter group permits transmission of at least infrared ray in each of a first wavelength range and a second wavelength range which are not overlapped with each other.

Abstract: A radiation thermometer includes a barrel, an infrared sensor, a first aperture, an infrared absorption structure, and a reflection structure. The barrel includes an infrared inlet port formed on a front end thereof. The infrared sensor is disposed on a base end side so as to be opposite to the infrared inlet port in the barrel. The first aperture divides between the infrared inlet port and the infrared sensor in the barrel. The infrared absorption structure is disposed on at least a part of an inner end surface on the base end side in the barrel or of an outer surface of the infrared sensor. The reflection structure is disposed on at least a part of an inner peripheral surface on the base end side relative to the first aperture in the barrel or at least a part of the first aperture which is located toward the infrared sensor.

Abstract: In order to provide a radiation thermometer with which a temperature of a measurement object disposed in a chamber configured to form plasma therein can be accurately measured in a noncontact manner from outside of the chamber, the radiation thermometer includes an infrared sensor and a window temperature compensation part. The infrared sensor is disposed outside the chamber configured to form plasma therein, and is configured to detect infrared ray emitted from the measurement object in the chamber through a transmission window provided in the chamber. The infrared sensor is configured to output an output signal according to energy of detected infrared ray. The window temperature compensation part is configured to compensate for a pre-compensation temperature of the measurement object being indicated by the output signal of the infrared sensor, on the basis of a temperature of the transmission window.
