IPC: B23K26/32
Filed: 1992-12-25
Abstract: PURPOSE:To obtain stable penetration and besides, to obtain a weld zone without failure by using a wire having specified content of Si, Mn, Fe and Al at the time of subjecting the copper structure to laser beam welding. CONSTITUTION:When a lap part, etc., of a copper pipe 2 and a copper mesh fin 1 are subjected to laser beam welding, the wire 8 having the content of Si, Mn, Fe, Al and Ni >=0.4% in total and having the composition consisting of each content of Si, Mn, Fe and Al <=15% is supplied.

IPC: H01G13/00
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a quality determining method, whereby the quality state of a capacitor can be determined in a short time. SOLUTION: This determining method makes a quality determination on a capacitor by using a charging property for applying dc voltage to a capacitor. A standard selection current value I0 of a dielectric polarization component is determined in advance regarding the capacitor, and an evaluation function n(t) is computed by a logarithmic value of the difference between a measurement current value m(t) of the measured capacitor and the standard selection current value I0, or the difference between the respective logarithmic values. Then a quadric curve approximation is made on the evaluation function n(t). Subsequently, when the secondary coefficient of a quadric curve approximate expression is positive, the capacitor is determined as being defective, and when the coefficient is negative, the capacitor is determined as being non-detective.
