Abstract: An image forming apparatus to which a cartridge including a cartridge substrate is attachable includes a main body electrical substrate, a main body ground terminal connected to the main body electrical substrate and configured to take a ground voltage, a first main body terminal connected to the main body electrical substrate and configured to transmit one of a power supply voltage, a data signal that indicates information, and a synchronization signal, a second main body terminal connected to the main body electrical substrate and configured to transmit remaining two of the power supply voltage, the data signal, and the synchronization signal. The cartridge substrate includes a cartridge ground terminal connected to the main body ground terminal, a first cartridge terminal connected to the first main body terminal, and a second cartridge terminal connected to the second main body terminal.

Abstract: A game management system that retrieves a delay time of each of a plurality of user devices playing a game; stores the delay times retrieved from each of the plurality of user devices; and transmits an instruction to synchronize game progress to each of the user devices, the instruction including an offset time determined based on a maximum value of the stored delay times.

Abstract: A brushless D.C. motor wherein one of projected stator poles positioned to be mutually equally spaced in mechanical angle is made sufficiently smaller than the other as partly cut off at circumferentially expanding pole tooth part, the stator poles being respectively polarized depending on controllably varied direction of direct current to coils on the poles by means of a rotor position detecting Hall element which detects the polarity at a predetermined position of the rotor, for allowing the rotor to self-start constantly in one direction with a remarkably increased starting torque.
