Title: Amplifying device
Inventor: UTSUNOMIYA MASAAKI
IPC: H03F3/68
Filed: 1981-09-03
Abstract: PURPOSE:To reduce greatly the output distortion component, by extracting the distortion component through a comparison between a signal containing the distortion component to be fed back of an amplifying means containing a negative feedback circuit and an input signal and then synthesizing the signal containing the amplified distortion component and the output of the amplifying means. CONSTITUTION:An amplifier 12 produces a distortion component N at its output with bare gain A1 and receives a shallow feedback with feedback factor beta1 from a feedback circuit 13. As a result, the apparent distortion of the amplifier 12 is reduced and approximately equal to N/(1+beta1A1). The signal sent back through the circuit 13 contains a distortion equivalent to beta1-fold value as much as the output. Thus the difference is obtained between an input signal and a feedback signal through a differential amplifier 14, and the distortion component of an opposite phase is amplified to be added with the output of the amplifier 12. Thus the distortion component is eliminated.

IPC: H05K1/11
Filed: 1986-06-18
Abstract: A self-heating and self-soldering bus bar for use in many applications. The pins of the bus bar are quickly and directly heated to a predetermined autoregulated temperature without significantly raising the temperature of the body of the bus. Thusly a bus bar may be mounted while maintaining thermal balance and mechanical integrity of all wotk pieces. The present invention avoids the problems normally associated with excess thermal expansion experienced when a bus bar is heated incidental to the heating of its contact points. A majority of this incidental heating is eliminated by direct quick heating of the mounting pins.
