Abstract: An electronic apparatus includes an operation member that is rotationally operable, a rotation detection substrate provided with a rotation detector configured to detect rotation of the operation member, a capacitance detector provided inside the operation member and configured to output a detection signal in accordance with capacitance, a signal transfer unit configured to transfer the detection signal to the rotation detection substrate, and a touch operation detector to which the detection signal is input through the rotation detection substrate, the touch operation detector being configured to detect a tap operation and a slide operation as a touch operation onto an outer surface of the operation member based on change in the detection signal due to the touch operation.

Abstract: An electronic apparatus includes an operation member that is rotationally operable, a rotational operation detector configured to detect a rotational operation onto the operation member, a touch operation detector configured to detect a touch operation onto the operation member, a state detector configured to detect a state of the electronic apparatus, and a processor configured to execute the instructions to execute a function in accordance with the rotational operation and the touch operation, and change setting about the rotational operation and the touch operation in accordance with the state.

Abstract: A turbocharger includes a turbine housing configured to accommodate a turbine wheel provided at one end of a rotation shaft, a bearing housing joined to the turbine housing and in which a bearing for supporting the rotation shaft is provided; and a variable nozzle unit that is disposed between the turbine housing and the bearing housing. The variable nozzle unit includes a nozzle ring disposed around a rotation axis of the rotation shaft and a support ring provided adjacent to the nozzle ring that includes an outer peripheral portion partially in contact with the turbine housing. One or more non-contact portions are formed in the outer peripheral portion of the support ring and do not contact the turbine housing.
