Title:
METAL THIN FILM FOR METAL CATALYST CARRIER AND METAL CATALYST CONVERTER EMPLOYING THE METAL THIN FILM
Document Type and Number:
WIPO Patent Application WO/1999/008789
Kind Code:
A1
Abstract:
A plurality of the peak parts (5a) and a plurality of the valley parts (5b) of a corrugated metal thin film (5) are alternately provided in a waveform propagating direction (61). In the metal thin film (5), a plurality of shelf parts (5f), a plurality of cutout valley parts (5d) and a plurality of cutout peak parts (5e) are respectively provided. The shelf part (5f) is placed between the peak part (5a) and the valley part (5b), is extended in a folding direction (60) and in the waveform propagating direction (61) and connects the adjacent peak part (5a) and valley part (5b) to each other. The cutout valley part (5d) is formed by bending a part of the peak part (5a) which is defined by two cut lines provided separately in the folding direction (60) along the border lines between the peak part (5a) and the shelf parts (5f), so as to protrude partially in the same direction as the valley part (5b). The cutout peak part (5e) is formed by bending a part of the valley part (5b) which is defined by two cut lines provided separately in the folding direction (60) along the border lines between the valley part (5b) and the shelf parts (5f), so as to protrude partially in the same direction as the peak part (5a).
