Abstract: A rotor includes a first resin portion formed the periphery of a main shaft; a first core disposed the outer circumferential portion of the first resin portion; a magnet attached to the radial outside of the first core; and a second core disposed the radially outside end face of the magnet, wherein a plurality of structures in each of which the magnet is sandwiched between the first and second cores are disposed circumferentially around the main shaft, and a second resin portion is formed between the circumferential end faces of adjacent second cores and between the circumferential end faces of adjacent magnets, wherein the first core has a division surface on which the circumferential end faces of itself and an adjacent first core are in surface contact with each other, and wherein the second core is not in contact with an adjacent second core.

Abstract: A pack battery charging method is a charging method for connecting pack battery to charger and charging pack battery at a constant voltage and a constant current. Pack battery detects a degree of deterioration of battery and a supply voltage at which charger charges pack battery, and specifies a charging termination current from both the supply voltage of charger and the degree of deterioration of battery to perform charging.

Abstract: A display control apparatus includes a memory and a processor coupled to the memory. The processor is configured to perform first executing first display control with respect to a screen, corresponding to a moving quantity of a first operation on a sensor, changing an operation mode with respect to the screen when detecting a second operation different from the first operation on the sensor, and second executing second display control with respect to the screen, corresponding to the moving quantity of the first operation on the screen, after changing the operation mode.

Abstract: A display device includes an input unit that receives input of two-dimensional information, a display that displays a screen and a control unit. When determining that one of a plurality of blocks into which the screen is two-dimensionally divided is selected based on a one-dimensional component of the information received by the input unit, the control unit magnifies and displays the selected block on the display with a first magnification factor which allows visual recognition of remaining blocks none of which has been selected. When detecting decision to magnify the selected block, the control unit magnifies and displays the selected block on the display with a second magnification factor larger than the first magnification factor.

Abstract: The power source apparatus enables each battery pack to be charged with power supplied from an external charging power supply, and allows power stored in each battery pack to be output externally. Each battery pack is provided with battery pack fault output terminals to send battery pack error signals to other battery packs or to the protection unit when a malfunction occurs. The protection unit is provided with protection unit input-output terminals to connect with battery pack fault output terminals, and a protection circuit capable of cutting-off battery pack current. When a battery pack malfunction occurs, a battery pack error signal is output from the battery pack fault output terminals to the protection unit input-output terminals. When the protection unit detects a battery pack error signal, the protection circuit cuts-off current.

Abstract: The DJ controller 10 has a load operation member 82 that loads audio signals to each channel, a synchronization button 84 that realizes a beat synchronization function, and a channel fader 85 that reproduces the loaded audio signals by the fader start function corresponding to each channel.

Abstract: In a rack-mount power supply device, a plurality of battery packs are removably placed in a rack main body. In each battery pack, a battery including a plurality of unit cells is housed in an outer case, and positive and negative output terminals are provided so as to come out on a back surface of the outer case. The rack main body includes a plurality of housing spaces housing the battery packs, respectively, and includes input terminals on a facing surface which is an inner surface of each housing space and which faces output terminals, the output terminals being to be electrically connected to the input terminals in a fitting state. In the rack main body, the input terminals are wired in a predetermined connection state on the back sides of the respective facing surfaces.

Abstract: A program information acquisition apparatus includes a program information acquisition unit, a program information accumulation unit, and a program information acquisition determining unit. In this configuration, a start of an acquisition operation by the program information acquisition unit is determined based on an information accumulation status of the program information accumulation unit. Thus, program information distributed from a desired reception target can be accumulated as the latest information as much as possible. Since unneeded program information is not acquired, program information acquisition with high energy saving effects is made possible.
