Abstract: There is provided a recording apparatus including: a recording part configured to perform, with a recording material, a recording of an image with respect to a recording medium; and a controller configured to control the recording part in a plurality of modes. The plurality of modes includes a first mode and a second mode. The controller is configured to adjust an amount of the recording material to be used at a time of the recording in the second mode. An adjustment width in a direction of decreasing the amount of the recording material in the first mode is smaller than an adjustment width in the direction of decreasing the amount of the recording material in the second mode.

Abstract: There is provided a recording apparatus including: a recording part configured to perform a recording of an image onto a recording medium with a recording material; and a controller configured to adjust, based on an adjustment value, an amount of the recording material which is to be used at a time of the recording. The controller is configured to execute, based on an index value regarding dirtiness, a changing processing of changing at least one of the adjustment value and a value regarding the adjustment value, in a direction of decreasing the amount of the recording material.

Abstract: In a rotating machine control device which controls an alternating current voltage command which is transmitted to an electric power converter, the alternating current voltage command is generated so that 1f component of the phase current may follow a current command. However, when the rotor position information by a position detecting element which detects the position of the rotor of a rotating machine has an error, an offset component is produced in the phase current. A controller includes an offset compensation part which calculates an offset compensation amount, from a detection result of the detection current so that the offset component of the detection current of the current detecting element may be decreased, and performs an addition or subtraction operation of an offset compensation command to the alternating current voltage command which a voltage command generation part outputs.

Abstract: This motor control device controls a motor having a first stator winding, a second stator winding, and a field winding whose response to a current command is slower than those of the first stator winding and the second stator winding, and includes: a parameter acquisition unit which acquires motor state data and a motor parameter corresponding to the motor state data; and a current command calculation unit which calculates current commands for the windings on the basis of a torque command for the motor and the motor parameter. The current command calculation unit includes a response delay reproduction unit which reproduces response delay of field winding current in a field winding current command, and calculates a first stator winding current command and a second stator winding current command, using the field winding current command in which the response delay is reproduced.
