Abstract: A control apparatus includes: a determiner configured to determine, for each indicator of a plurality of indicators, whether an event relevant to a change in the respective indicator has occurred, the plurality of indicators relating to an environment in which crops are grown, each indicator of the plurality of indicators being detected by one or more sensors of a plurality of sensors; an identifier configured to identify, based on a result of a determination executed by the determiner, a plurality of target sensors from among the plurality of sensors, a number of the plurality of target sensors being less than a number of the plurality of sensors; and a transmission instructor configured to instruct each target sensor of the plurality of target sensors to transmit a respective detection result.

Abstract: A terminal includes: a control section that generates Capability information including UE Capability for a Power Class; and a transmission section that transmits the Capability information. The Power Class is specified by four items of Max Total Radiated Power (TRP), Max peak Equivalent Isotropic Radiated Power (EIRP), Min peak EIRP, and Spherical coverage EIRP, and an Inter-band-Carrier-Aggregation (CA) specified value of at least one of the Max peak EIRP and the Min peak EIRP for Inter-band CA in which a plurality of bands are used is defined by a method different from a method for a non-Inter-band-CA specified value.

Abstract: A friction stir welding device includes a pair of workpiece surface plates between which a gap extending along a welding line between workpieces is formed; a welding device body including a rotatable friction stir welding tool protruding upward from the gap; and a linear guide mechanism and a moving device for the welding device body. The moving device has a configuration in which a pair of pin racks extending in a direction along the gap are disposed at symmetrical positions on both sides in a width direction with a position immediately below a tool movement path of the friction stir welding tool as a symmetrical axis, and pin gears that individually mesh therewith are provided in the welding device body so as to be rotatably driven. Respective sets of a pin rack and a pin gear are alternately brought into a strong meshing state during the movement of the welding device body by causing the locations of pins and teeth thereof to deviate from each other by a half pitch.
