Abstract: A rotor constituting a rotating electric machine includes a rotating shaft and a permanent magnet. A sleeve covering the outer surface of the permanent magnet is attached to the rotating shaft. A resin coating layer is formed on an outer circumferential wall of the sleeve. The resin coating layer includes a base portion and a plurality of ridges formed on the outer circumferential wall of the base portion. A riblet recessed relative to the plurality of ridges is formed between the plurality of ridges.

Abstract: A rotor constituting a rotating electric machine includes a rotating shaft and a permanent magnet. A sleeve covering the outer surface of the permanent magnet is attached to the rotating shaft. The sleeve is made of a carbon fiber reinforced polymer. A resin film is joined to an outer circumferential wall of the sleeve via a joining material. A plurality of ridges are formed on the outer circumferential wall of the resin film. A riblet recessed relatively to the plurality of ridges is formed between the plurality of ridges.

Abstract: An information terminal system includes a mobile terminal having a display and a glasses-type wearable terminal being communicably connected to each other. The glasses-type wearable terminal includes a display unit configured to display an operable extended screen by projecting the extended screen in a view of a user based on display information of the extended screen received from the mobile terminal, a first detection unit configured to detect a user operation, and a first transmission unit configured to transmit information indicating the user operation to the mobile terminal. The mobile terminal includes a second transmission unit configured to transmit the display information of the extended screen to the glasses-type wearable terminal, and a processing unit configured to execute processing corresponding to the user operation based on the received information indicating the user operation.
