The power consumption of a control device or a data processing system is reduced. Safety is enhanced. An electronic device is operated in a simple way. A control device includes an arithmetic circuit, an input unit, and a power management unit. The input unit includes a sensor element. The power management unit has a function of controlling supply and shutdown of power to the arithmetic circuit. The power management unit has a function of supplying power to the arithmetic circuit in response to a detection signal output from the sensor element. The sensor element includes one or more selected from an acceleration sensor, an angular velocity sensor, and a magnetic sensor. The arithmetic circuit includes a register. The register includes a first circuit and a second circuit. The register has a function of storing, in the second circuit, first data stored in the first circuit in a period during which the power management unit supplies power to the arithmetic circuit and retaining the first data, in a period during which the power management unit stops power supply to the arithmetic circuit. The arithmetic circuit has a function of generating second data with use of signal data output from the sensor element and the first data.

An angle adjustment device capable of being kept at a desired angle is provided. The angle adjustment device can fix and keep the relative positions of the first base component and the second base component, and a support with a combination of the angle adjustment device and components such as a flat plate can keep the entire body in a shape opened on a plane, a folded shape, a shape kept at a desired angle, or the like. In addition, the angle adjustment device can make a bending movement in one direction, which prevents bending in a reverse direction. Therefore, it is possible to prevent an accidental bending movement of an apparatus including the angle adjustment device to prevent breakage or the like of the apparatus.

A turbine rotor in an embodiment is configured by joining a rotor component member and a rotor component member together by bolt fastening with an abutting end surface of the rotor component member and an abutting end surface of the rotor component member abutting on each other. The turbine rotor includes: a cylindrical recessed portion that is formed at the abutting end surface and is recessed in an axial direction; an axial passage bored from a bottom surface of the cylindrical recessed portion in the axial direction; an introduction passage introducing the cooling medium into the axial passage; a discharge passage discharging the cooling medium from the axial passage; and a sealing member that is arranged in the cylindrical recessed portion and seals one end of the axial passage.
