Abstract: An object is to provide a data collection device and the like capable of reducing a load on an IoT terminal in metadata transmission and power consumption associated with the metadata transmission. In the present invention, a controller is provided on a data collection side that collects metadata, the metadata transmitted from an IoT terminal is grasped, and the IoT terminal is instructed to reduce the transmission frequency of metadata that does not need high real-time property according to a sensor, the type of the IoT terminal, or the like. The IoT terminal transmits the metadata only at a window time (transmission timing, data size, metadata type, or the like) permitted by the metadata controller. As a result, the IoT terminal transmits the metadata only at a limited timing, and thus can reduce a transmission load and power consumption.

Abstract: A quartz glass provides an opaque quartz glass having high light-shielding property, excellent mechanical strength and excellent cleaning resistance against hydrofluoric acid. By setting the maximum width of the amorphous bubbles existing in the opaque quartz glass to an average of 3 to 15 ?m and the density to 2.15 g/cm3 or more, the mechanical strength after baking and the cleaning resistance by hydrofluoric acid are improved. The opaque quartz glass has a whiteness at a thickness of 10 mm of 75 to 90%, the reflectance of light with a wavelength of 0.24 to 2.6 ?m at a thickness of 4 mm is 60 to 85%, and the bending strength after baking is 95 MPa. In addition, a foaming agent may be mixed in the opaque quartz glass. An opaque quartz glass having cleaning resistance against acid can be obtained.

Abstract: An object is to closely observe, by means of images of a camera having high performance specifications, changes in a structure due to heating or cooling of the structure to a temperature beyond a service temperature limit of the camera having high performance specifications and returning from that temperature to room temperature. A structure observation device includes: a camera case of a rectangular three-dimensional shape, having a glass window of heat-resistant and/or cold-resistant glass on at least one side of the three-dimensional shape; heat insulating walls covering the camera case except for the glass window; a fluid supply port and a fluid discharge port through which a cooling or warming fluid is circulated into; and a camera that is disposed inside the camera case and captures a still image or a moving image through the glass window and externally outputs or internally stores data of the captured image.

Abstract: The purpose of the present invention is to provide a method for synthesizing ammonia and an apparatus for the method. The method for synthesizing ammonia according to the present invention comprises: a step of melting a metal containing at least an alkali metal; and a step of supplying a hydrogen gas and a nitrogen gas to the molten metal.

Abstract: The server apparatus is applied to a game system which has a storage unit storing gaming dynamic images different from each other in association with a stream ID for identifying each gaming dynamic image. The game system acquires a playing dynamic image photographed by a portable phone and a stream ID of the playing dynamic image via a network. Base on the acquisition result, the game system determines the gaming dynamic image whose stream ID corresponds to the stream ID of the playing dynamic image acquired as a target gaming dynamic image, and provides a dynamic-image delivery service so that a delivery screen is displayed at each personal computer, the delivery screen including a composite dynamic image where the playing dynamic image and the target gaming dynamic image are synthesized.

Abstract: A management server issues a game link identifier associated with friend network identification information corresponding to an inviting game and sends the game link identifier to a terminal apparatus corresponding to the friend network identification information. In the terminal apparatus, the game link identifier is passed from the inviting game to an invited game, and the program of the invited game sends the passed game link identifier and identification information of an inviting user, corresponding to the invited game, to the management server. The management server searches already issued game link identifiers, and, when a game link identifier that matches the received game link identifier is found, associates friend network identification information corresponding to the invited game associated with the received game link identifier, with the friend network identification information corresponding to the inviting game associated with the issued game link identifier.

Abstract: A terminal apparatus includes an inquiry unit that sends an inquiry, from a game used in the terminal apparatus among at least two games provided by an application system, about an invitation to another game, to an invitation information management unit of a management apparatus; an invitation information receiving unit that receives invitation information corresponding to the inquiry; and a display control unit that displays, on a display unit, details of the invitation according to the invitation information.

Abstract: A management server issues a token associated with friend network identification information identifying a user of a game provided by an application server, to the application server; receives the token passed from the game to another game on the basis of an operation of the user in a terminal apparatus where the game and the other game are available, from an application server that provides the other game; and manages, in association with each other, the friend network identification information related to the game and friend network identification information related to the other game for which the issued token matches the received token.
