  • Patent number: 7470847
    Abstract: An electronic percussion instrument pedal device uses a spring structure in a space between a bottom structure and a foot pedal board structure to regulate the movement of the foot pedal board structure. Even when the foot pedal board structure is not being moved, it is regulated by the above mentioned spring structure into a proper near horizontal position. If the foot board is stepped on, the coil spring will stretch and a load (stability) will become strong. As a result, when the foot board is in a position near the position in which it is not stepped on, the load is initially relatively light and then becomes heavier as the user continues to further step on the foot board. This is approximated to the action of an acoustic bass drum, and a good actuation feeling.

  • Patent number: 7215158
    Abstract: An operation switching circuit switches over two comparators, which receives communication data, in accordance with a normal mode and a standby mode of a microcomputer. A delay circuit delays a mode switching signal. The mode switching signal and the delayed signal are combined by an OR gate and an AND gate to two comparator control signals, which have different high level periods. The comparators are driven by the comparator control signals, while a multiplexer is driven by the delayed signal. When one comparator is switched from the inoperative state to the operative state, the other comparator is continued to be held operative for the delay period before being switched to the inoperative state.

  • Patent number: 7071671
    Abstract: A constant voltage supplying circuit including an output transistor is connected to a power source line and an output terminal. A base-emitter voltage of the output transistor is detected by a voltage detecting circuit composed of a transistor. A current-outputting circuit for supplying a current determined based on the voltage detected by the voltage detector to a reference voltage supplying circuit is used in the constant voltage supplying circuit. The reference voltage is supplied to a base of the output transistor to cancel a base-emitter voltage of the output transistor and to equalize the output voltage to a voltage generated in a reference voltage generating element included in the reference voltage supplying circuit. In this manner, the output voltage is kept constant notwithstanding variation of output current.
