Title: Aluminum tube with zinc coating
Inventor: YANAGAWA YUTAKA
IPC: F28F19/06
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To provide an aluminum tube capable of preventing a peeling off of fins and having an excellent pitting corrosion resistance. SOLUTION: A zinc coated aluminum tube 10 has a zinc coating amounting to less than 7g/m<2> at portions where fins 20 are brazed and not less than 7g/m<2> and not more than 25g/m<2> at remaining portions other than the brazed portions 20. In this manner, since the portions of the aluminum tube 10 where the fins 20 are brazed are provided with a small amount of zinc coating, brazing filler metal becomes a base material as a result of diffusion of a large amount of zinc and corrodes preferentially so that a peeling off of the fins 20 can be prevented. Namely, a small amount of zinc coating is compensated by the preferential corrosion effect of the fins. Since the remaining portions of the aluminum tube 10 where fins are not brazed have a large amount of zinc coating, pitting corrosion does not occur on these portions.

Filed: 1990-01-31
Abstract: PURPOSE:To prevent needlelike protrusions from being generated during the cutting process of a pole plate and also prevent an active material from falling off a core of an electrode by providing long holes in the portion around the core. CONSTITUTION:In a portion extending along a cutting line A-A' long holes 3 are punched with their longitudinal axes extended in the direction perpendicular to the cutting line and circular holes 4 are punched in a portion other then the cutting line portion. A paste 1 composed mainly of CdO is applied to a core 2 comprising a punching metal plate thus punched and the core is formed into a strip pole plate after drying and chemical conversion processes etc. During the cutting process of the strip pole plate, each long hole 3 is cut using a guide for positioning which is wider than the band pole plate by 1 to 2mm, so that an electrode is completed. Thereby the angle of the end of each needlelike protrusion is more than 30 deg. with respect to the long side of the portion around the core and thus each protrusion is prevented from passing through a separator so as to reduce the rate of imperfect insulation of the wound electrode.

Filed: 1989-01-31
Abstract: PURPOSE:To expand the setting range of wave length sensitivity by providing a photo sensitive layer composed of semiconductor which receives light and generates carrier, and a channel composed of semiconductor whose recombination current amount is controlled by field effect. CONSTITUTION:When light hnu enters a photo sensitive layer 4, carrier generates in the photo sensitive layer 4, and electric field E is formed by electric charge concentrated on the I-side of a channel 1.

Water 8 overflowing the undulating weir 2 flows down over the flexible film 1, and thereby the effluent has a gentle drop slope to enable the reduction in noise produced due to dropping of the effluent. Additionally, the flexible film 1 may be eliminated.
