摘要:
Receiving paper (7) discharged from a facsimile receiver (2) is taken into the sealing device (1) by means of feed mechanism (8) and is transported, e.g. between plates (28, 29) and belts (22, 23), to first folding means (35, 36, 42,46) where it is folded in double and stacked in folded condition on a tray (43). The stacked paper is then folded again, along with envelope paper (52), by means of second folding means (56, 58, 59) which also seal the folded receiving paper (7) inside the folded envelope paper (52) by adhering the edges of the envelope paper.
摘要:
A highly active powder catalyst with a high concentration of platinum group elements is prepared from an amorphous alloy consisting of at least one of the valve metals, at least one of the platinum group elements and at least one element selected from Ni and Co by immersion in hydrofluoric acid. A highly active electrode is prepared by mixing the above-mentioned powder catalyst with carbon black and a hydrophobic fluorocarbon polymer, coating the mixture onto a conductive substrate and baking same.
