Title: Muffling device
Inventor: FUKUI SEIJI
IPC: G10K11/16
Filed: 1988-12-19
Abstract: PURPOSE:To reduce a noise using a phenomenon that a noise from a noise source and an opposite phase sound from an opposite phase sounding means are offset with each other by arranging the opposite phase sounding means in the neighborhood of the noise source. CONSTITUTION:The sound generated from a sound source data part is passed through a phase adjusting means and a level adjusting means, made into the sound having the opposite phase to the phase of the noise from the noise source, and sent from the sounding means. At this time, plural sound receiving mean detect the noise from the noise source and a synthetic sound from the sounding means and send a sound pressure level through a sound pressure deciding means to a control means. The control mean controls the phase adjusting means and the level adjusting means so that the sound pressure level from the sound pressure deciding means can be the minimum. Thus, when the noise to be generated from a heat exchanger 2, a fan 3, a wind tunnel 4, etc., and the opposite phase sound to be generated from the sounding means 5 are heard at the inside of a room, the noise and the opposite phase sound are offset with each other, and the level is widely reduced.

Title: Low consumed power device
Inventor: SUZUKI TAKAHIRO
IPC: G06F1/32
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To lower the power consumed in a device which is operated by limited electric power from a battery, etc. SOLUTION: Devices 101 are divided into circuit blocks 102-1 to 102-n by operation functions, and the operation of a circuit block which wasting electric power by performing unnecessary operation is stopped by connecting and disconnecting the electric power or synchronizing signal placing the circuit blocks 102-1 to 102-n in operation, block by block, to reduce the consumed power in the whole device.  Further, when a transmitted frame is received, a device for transmission compares its station address with address information on the received frame and actuates a controller such as a microcomputer only when the received frame is addressed to its station to enter a reception state, but automatically cancels the frame without actuating the controller such as the microcomputer if the received frame is a transmitted frame addressed to another station, so that the consumed power in the whole system is reduced as a result.
