Abstract: A radio communication apparatus includes a plurality of antennas, a radio transmission unit configured to execute radio transmission processing on data to be transmitted from the plurality of antennas, and a processor connected to the radio transmission unit. The processor executes a process including acquiring beam group specification information that specifies a beam group that is capable of being formed when the data to be transmitted is transmitted, forming at least one beam included in the beam group, and correcting an envelope of a beam group using correction factors, the beam group including the at least one beam formed, the correction factors corresponding to the beam group specification information.

Abstract: An imaging apparatus, which can be mounted with an interchangeable lens and operates with power from a battery, includes: a connection detachably connected to the interchangeable lens; a controller that controls a lower-limit voltage indicating a lower limit for supplying power from the battery; and a selector that selects one operation mode from a plurality of operation modes for operating the imaging apparatus with power from the battery, wherein the controller switches the lower-limit voltage among a plurality of set values respectively corresponding to combinations of types of the interchangeable lens and the plurality of operation modes on a basis of the interchangeable lens connected to the connection and the operation mode selected by the selector.

Abstract: An imaging apparatus which can be mounted with a first battery and a second battery includes: a load circuit configured to operate the imaging apparatus; and a control circuit configured to control power supply to the load circuit based on a first battery voltage in the first battery and a second battery voltage in the second battery. In a high-load mode, the control circuit selects any one of the first battery, the second battery, and a combination of the first and second batteries in accordance with the first and second battery voltages, to supply power to the load circuit. In a low-load mode, the control circuit selects either one of the first battery and the second battery in accordance with the first and second battery voltages without selecting the combination of the first and second batteries, to supply power to the load circuit.

Abstract: An optical transmission module includes a receptacle-type optical part, a holder part, and a cover part. The receptacle-type optical part includes a resin molding and a device part. The resin molding is provided with a ferrule insertion hole extending in a first direction and a first fitting part in a surface perpendicular to the first direction. The holder part contains resin and includes a back surface plate provided with a second fitting part fitted to the first fitting part and an upper surface plate provided with a third fitting part provided in parallel to the first direction. The cover part is inserted along the first direction between the holder and receptacle-type optical part. The cover part includes an upper surface plate provided with a fourth fitting part capable of fitting to the third fitting part. The cover part is extractable along the first direction from a housed position.

Abstract: A sensor device includes: a casing provided with an opening; a cover member covering the opening; a gasket interposed between the cover member and the casing; and a fixing cover which fixes both the gasket and the cover member to the casing. A plurality of welded portions bonding the casing and the fixing cover together are provided in a region outside the cover member such that the welded portions are distant from each other.

Abstract: An optical electronic device comprises: a casing having an external surface provided with an opening; a cable inserted through the opening; a bush attached to the cable; and a resin sealing portion. The bush is brought into close contact with the cable and the casing to seal a gap between the cable and the casing. The resin sealing portion is provided locally inside the casing to cover an internal surface of a portion of the casing surrounding the opening and a surface of a portion of the cable drawn from the opening into the casing.
