Title: Surface treating method for aluminum foil
Inventor: TAMURA TOORU
IPC: C23C22/00
Filed: 1978-01-31
Abstract: PURPOSE:To remarkably reduce the leakage current of the anode foil of an Al electrolytic capacitor by heat treating an Al foil of low purity at a specific temp., followed by dipping in an aq. soln. of phosphoric acid and an aq. soln. of nitric acid in succession, washing and chemical treatment. CONSTITUTION:An Al foil of such a purity that obtd. by rolling primary electrolytic Al is heat treated at 400-600 deg.C for 10-60 min to precipitate impurity Fe on the Al grain boundaries. The foil is then cooled to room temp., dipped in a 2-20% aq. soln. of phosphoric acid at room temp.-70 deg.C for 5-10 min, further dipped in a 2-20% aq. soln. of nitric acid at room temp.-70 deg.C for 2-10 min to remove Fe, Fe-Al cpd. and insol. Al phosphate as impurities, washed with water, and chemically treated to form an oxide film on the foil surface. Thus, a chemical film having a leakage current about equal to that of an Al foil of 99.99% purity can be obtd. from a foil of primary electrolytic Al of about 99% purity.

Inventor: ARAI KUNIO
IPC: F25C1/24
Filed: 1994-02-01
Abstract: PURPOSE:To reduce irregularity of a water supply amount to an icemaking tray by preventing water from remaining in a feed water pipe. CONSTITUTION:Water supplied from a feed water tank 17 to a water supply chamber 15a is fed to a constant volume chamber 15b through an orifice 16a of a partition wall 16. The water fed to the chamber 15a is pumped out by a feed water pump 19, and then supplied to an icemaking tray 13 through a feed water pipe 20. In this case, when water entrained with the air is pumped out by the pump 19, the pump 19 is stopped, and then the water is separated into a water receiving tray side oblique part 20a and an icemaking tray side oblique part 20b. However, since the atmospheric air is sucked into the pipe 20 through a trap 21 and a suction hole 20d, the waters in the parts 20a and 20b are returned to the chamber 15b and the tray 13.
