Abstract: PURPOSE:To remove Sb and Cu from regenerated solder contg. Sb and Cu as impurities by melting the solder in the air, adding a specified Al-Mg alloy, melting it, and carrying out agitation. CONSTITUTION:Regenerated solder contg. Sb and Cu as impurities is melted in the air, and an Al-Mg alloy contg. 35-70wt% Mg and having 440-450 deg.C m.p. is added to the molten solder at 450 deg.C by a proper amount in accordance with the Sb and Cu contents of the solder. The alloy is melted, and agitation is carried out. Sb and Cu react preferentially with Mg and Al, respectively to form MgSb2 and CuAl2 as intermetallic compounds. The agitated solder bath is slowly cooled after the lapse of 30-60min. The intermetallic compounds rise to the surface of the bath at 250-300 deg.C by the difference in specific gravity, so they are removed. Excess Mg and Al in the bath are oxidized by blowing air, allowed to rise to the surface, and removed.

Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To decrease error signals included in a reproduced digital data signal by providing a device with control means, capable of respectively separately controlling optical make/break means for opening and closing the incidence of gate light, signal light and reference light on recording media. SOLUTION: When irradiation on a recording medium 10 with the gate light is shut off by closing a shutter (S8), a built-in timer starts clocking operation and a controller attains a standby state (S9). The charge carriers photoexcited thus far during daytime excitation level begin to gradually return to a base level, while the exposure of light interference patterns continues. After the gate light is shut off, the carriers in the crystal excited to an intermediate excitation state successively return to the base state, and when the time T3 required before information recording is no longer possible elapses, the exposure of the light interference patterns is ended. At this time, the charge carriers photoexcited at an intermediate excitation level do not possess energy of such size as to negate the space electric fields formed to include the information signals.

Abstract: PURPOSE:To prevent a wrong trip by connecting two auxiliary relays to be operated with the closing signal with time limits different from each other to an operating circuit of a leased breaker. CONSTITUTION:In the case that an A power capacitor bank leased breaker 52AC is operated for input during the stop of a B power capacitor leased breaker 52BC, when an operating switch 3-52AC of the breaker 52AC is operated for input, a holding relay 52ACX is excited to turn ON a usually open contact 52ACX-a. A time limit relay 52ACXT1 is thereby operated with a time limit to close the breaker 52AC, and the current flowing to the breaker 52AC becomes maximum at the initial time, and thereafter, it is reduced to be the mean rated current. At this stage, even if the current becomes maximum, an induction disc element 51AC-INDU of an overcurrent relay 51AC does not reach the operating condition, and even if a holding relay 52BCX-b connected to the element 51AC-INDU is turned ON, the breaker 52AC does not trip. But, an instantaneous element 51AC-INST is operated in response to the accident detecting current. A wrong trip can be thus prevented.
