Abstract: A communications device includes a processor configured to detect a wirelessly communicating base station, using a given interval; determine whether identification information of the detected base station matches identification information of a base station detected last time; and set the given interval to a second interval upon determining that the identification information of the detected base station and the identification information of the base station detected last time match. The second interval is longer than a first interval that is set upon determining that the identification information of the detected base station and the identification information of the base station detected last time do not match.

Abstract: A communication apparatus includes a display configured to display an image; a processor configured to control the display; and a storage configured to store information processed by the processor. The processor, in each communication area of a base station that is communicable with the communication apparatus, upon connection to an access point enabling communication with the base station by a different communication method, correlates and stores to the storage as connection history information, a connection history of connection to the connected access point and the communication area, and when the display is caused to transition from a non-displaying state to a displaying state, scans the access point corresponding to the communication area, based on the connection history information.

Abstract: A coherent light source apparatus includes a coherent light source, a first optical system, a light deflection unit, a second optical system and a light mixing unit disposed in that order. The coherent light source forms a first light emission region, and light projected therefrom forms a second light emission region near the light deflection unit, which deflects light flux from the second light emission region.

The light deflection unit is configured to continuously changing a direction in which the light flux is deflected, thereby reducing speckling in light emitted from the light mixing unit.

Abstract: A command rotation speed is set to an initial rotation speed, and a forced commutation mode is started. In the forced commutation mode, a rotation speed is increased by a predetermined increase amount each time and forced commutation is executed until the rotation speed reaches a set rotation speed. Then, a switchover to the sensorless control mode is made when the rotation speed reaches the set rotation speed (S4) and a rotor position becomes detectable.

Abstract: When a forced commutation mode ends, a switchover to a sensorless control mode is made. The sensorless control mode immediately after the switchover to the sensorless control mode is executed with a power source current maximum value set at a value higher than a rated current value of a motor. The sensorless control mode immediately after the switchover is executed only over a predetermined period of time, and, after a lapse of the predetermined period of time, a steady sensorless control mode is executed. In the steady sensorless control mode, the power source current maximum value is set at a value equal to the rated current value of the motor.
