Title: Method of manufacturing noise suppressing laminated core and noise suppressing structure electromagnetic steel plate
Inventor: MATSUZAKI MAKOTO
IPC: H01F41/02
Filed: 2001-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a structure and a method of manufacturing the structure which can suppress core noise of an electric apparatus such as a transformer, an electromagnetic mixer, a reactor, etc. SOLUTION: Each one of electromagnetic plates of which the laminated core is composed has machined grooves which are in parallel with the width direction of the plates or inclined from the width direction and formed from end to end of the plate. The electromagnetic plates are layered so as not to stack the surfaces of the steel plates each other which are not machined, and adhesive resin is made to penetrate into the laminated core through the machined grooves by a capillary phenomenon to constitute an electromagnetic steel plate structure and to fix the laminated core by bonding. With such a constitution, the core is fixed as a whole by the adhesive resin, so that noise caused by magnetostriction, etc., can be reduced (several dB-scores dB) and hence the noise suppression can be achieved at a low cost.

Title: Monolithic adsl analog front end and its realizing method
Inventor: AGAH MICHAEL D
IPC: H04L27/00
Filed: 2001-09-05
Abstract: PROBLEM TO BE SOLVED: To provide a monolithic ADSL analog front end with less die area and power consumption. SOLUTION: Utilizing a synthesis impedance technology can remarkably reduce a gain of a transmitter line driver 506 and a gain of a receiver amplifier 508 so that analog transmitter and receiver filters 502, 504 are realized in a high voltage processing process. Since the signal gain of the transmitter line driver 506 and the signal gain of the receiver amplifier 508 are decreased and the analog filters 502, 504 are realized in the high voltage processing process, they are physically downsized so as to be adaptive to a higher noise source thereby reducing the die area and the power consumption being requirements in the ADSL analog front end.
