Title: Brazing method for aluminum material
Inventor: FUJIYOSHI TATSUYA
IPC: B23K1/19
Filed: 1985-05-21
Abstract: PURPOSE:To suppress the evaporation rate of zinc and to prevent the decrease of a corrosion preventive effect by subjecting an Al material, etc. coated with zinc to a preliminary heating treatment for the prescribed time in the atm. prior to soldering of said material in a furnace. CONSTITUTION:A condenser core 1 is tentatively assembled of a core material and fins constituted of the Al or Al alloy material. The core is first put into a preheating furnace 2 and is preheated for 5-60min at 400-580 deg.C. The zinc of the surface layer of the tube is oxidized and an oxide film is formed thereon. The preheated condenser core 1 is fed into a brazing furnace 3 in which an inert gaseous atmosphere of gaseous nitrogen is maintained. The core is heated to the prescribed temp. and is brazed via a non-corrosive flux. The oxide film formed by the preheating decreases considerably the evaporation rate of zinc. The decrease of the corrosion preventive effect arising from the decrease in the quantity of zinc is thus prevented.

Abstract: PURPOSE:To prevent the occurrence of crossover distortion while the dynamic range is expanded by constituting a full feedback amplifier through the parallel connection of the 1st and 2nd differential amplifiers and through the series connection of output transistors (TR) of each differential amplifier. CONSTITUTION:The non-inverting inputs and the inverting inputs are connected mutually in the 1st and 2nd differential amplifiers 6A, 6B and the 1st output TR 14a of the 1st differential amplifier 6A and the 2nd output TR 14b of the 2nd differential amplifier 6B are connected in series. When an input signal VIN is positive, the 2nd output TR 14b is activated as a load of the 1st output TR 14a and when the input signal VIN is negative, the 1st output TR 14a is activated as a load of the 2nd output TR 14b and they are loads having a large drive capability. Thus, the dynamic range is expanded, the waveform distortion caused in a single buffer amplifier is compensated and a buffer output without waveform distortion is extracted.
