Abstract: An equipment control system includes a disaster notification apparatus configured to transmit a disaster notification, and a wireless communication apparatus provided in a building. The wireless communication apparatus receives the disaster notification, and determines whether a user of a portable terminal is present in the building, based on a communication situation between the wireless communication apparatus and one or more portable terminals. Upon receiving the disaster notification, the wireless communication apparatus controls one or more pieces of equipment installed within the building, differently depending on whether the user of the portable terminal is present in the building.

Abstract: A control device includes: a memory; and a processor coupled to the memory and configured to: acquire congestion information indicating a congestion state of communication of wireless local area networks (LANs) which are connection destination candidates of a mobile terminal configured to switch a state thereof between a first state and a second state, in the first state the mobile terminal being wirelessly connected to a radio base station of a mobile communication network and not performing a detection operation of a wireless LAN among the wireless LANs, and in the second state the mobile terminal performing the detection operation and being wirelessly connected to a detected wireless LAN, and perform switching control for switching a state of the mobile terminal from the first state to the second state when the congestion information satisfies a given condition.

Abstract: There is provided a low loss slow wave transmission line that can be miniaturized. A slow wave transmission line of the present invention has a configuration which includes a repeated arrangement of a low impedance line and a high impedance line and in which the high impedance line is longer than the low impedance line in terms of a line length.

Abstract: A brazing filler metal is composed of gold, silver, copper, and an additive element including at least one kind of element out of aluminum, bismuth, gallium, germanium, indium, antimony, silicon, tin, lead, tellurium, and thallium, as main constituents thereof, wherein a total composition ratio of the additive element is in a range of more than 1 wt. % to less than 36 wt. %, and a composition ratio of the gold is less than 80 wt. %, and a composition ratio of the silver is less than 42 wt. %, so that the brazing filler metal joins metals for use as members of which decorativeness in external appearance is required, such as stainless steel and so on, at a low temperature which does not cause the crystal structure thereof to be coarsened, while securing excellent corrosion resistance and sufficient joining strength.
