Abstract: A server includes a control unit configured to extract, among facilities different from a power controller configured to execute power control including at least one of charging and discharging of an electrified vehicle, the facility that is available, during a reservation period for use of the power controller, to a user who uses the power controller during the reservation period and a communication unit configured to transmit information on the extracted facility to at least one of the electrified vehicle and an information device that are associated with the user.

Abstract: A server includes a control unit configured to extract from a plurality of items of the maintenance check those item(s) that can be performed within a reservation period reserved by a user of an electrified vehicle for power control including either or both of charging and discharging of a battery of the electrified vehicle, based on a length of the reservation period. The server further includes a communication unit configured to send information on the extracted item(s) to at least one device out of the electrified vehicle and a first information device of the user.

Abstract: A method of managing electric power supply and demand with a computer includes sending, from the computer, a message for making a request of an electrified vehicle with a driver and a passenger to participate in a demand response for adjusting supply or demand of electric power in a power grid, acquiring, by the computer, passenger information on at least one of an attribute and a preference of the passenger, and setting, by the computer, a first incentive for prompting the passenger to participate in the demand response based on the passenger information.

Abstract: A laser beam recording method and apparatus are constituted for recording an image by obtaining a laser beam whose optical intensity is modulated by controlling a drive current for a semiconductor laser on the basis of a light emission level instructing signal corresponding to an image signal, and scanning the laser beam on a photosensitive material. The optical output is stabilized by detecting the optical intensity of the laser beam and feeding back a feedback signal corresponding to the detected optical intensity to the light emission level instructing signal. A filter circuit formed so that the gain gradually increases from near to a cutoff frequency of a circuit for the optical output stabilization toward a higher frequency side is disposed in a stage prior to the circuit for the optical output stabilization.

Abstract: A sheet feed mechanism in a light scanning apparatus includes two pairs of rollers for gripping and feeding a sheet-like medium such as a stimulable phosphor sheet or a photographic film in a subscanning direction. The two pairs of rollers are spaced a distance smaller than the length of the sheet-like medium in the subscanning direction. While the sheet-like medium is being fed by the sheet feed mechanism in the subscanning direction, the sheet-like medium is scanned by a light beam deflected in a main scanning direction substantially normal to the subscanning direction, for thereby two-dimensionally scanning the sheet-like medium.

Abstract: A signal representing the period between adjacent positive-going edges and the period between adjacent negative-going edges of a pulse train generated by a rotary encoder coupled coaxially to a motor is compared with a reference period signal for the motor to produce a deviation signal. The rotation of the motor is controlled by the deviation signal.

Abstract: A brushless motor includes a plurality of stator armature windings having winding frames with spaces defined therein, respectively, a rotor mounted on a rotatable shaft and having field poles rotatable with respect to the armature windings, and a plurality of rotor position detectors such as Hall-effect devices disposed in the spaces, respectively, and having output terminals connected respectively to the input terminals of other armature windings, for continuously varying the currents flowing through the other armature windings dependent on signals indicative of the magnetic fluxes from the field poles as detected by the rotor position detectors.
