Title: Production of corrosion resistant silver alloy decorative parts
Inventor: SATOU ATSUSHI
IPC: C23C10/28
Filed: 1983-06-14
Abstract: PURPOSE:To produce silver alloy decorative parts having excellent corrosion resistance by coating silver on the surface of the silver alloy parts contg. a specific amt. of copper, subjecting said parts to a thermal diffusion treatment then to a heating and quick cooling treatment and a mechanical surface removing treatment thereby forming the inside phase and the outside phase into the specific two-phase state. CONSTITUTION:Silver is stuck by electroplating, etc. on silver alloy parts solutionized therein with 2-8wt% copper and the silver alloy parts are maintained at the temp. in the alpha phase region of said alloy and the region where the stuck silver and the alloy diffuse thermally, thereby providing certain gradient to the concn. of the copper from the surface. The alloy is then maintained at the lower temp. at which the alloy beta phase deposits. After the beta phase is deposited, the alloy is cooled quickly to obtain the alloy having the single phase in which the copper changes with a positive concn. gradient down to certain depth from the surface and the two phases of (alpha+beta) in the part deeper than the same. Such surface is removed by polishing, etc., by which the decorative parts consisting of the alpha single phase solutionized therein with >=0.5wt% copper on the outermost surface and the two phases of the hardened (alpha+beta) phase in the inside are obtd.

Title: Original feeding/sending device
Inventor: KIMURA YOSHIYUKI
IPC: B65H3/44
Filed: 1991-04-11
Abstract: PURPOSE:To feed/send an original by using a simple mechanism and with high productivity and reliability by moving a plurality of original placing tables, with the guiding direction changed in a space between an original feeding/sending position and a shunting position. CONSTITUTION:A plurality of bins 201 for originals are guided from a lower bin guide passage 221 toward the upper side, being held by a notch of a Geneva wheel 207, which is driven in its rotation by a wheel motor 231. After the bins 201 are detached form the lower bin guide passage 221, the direction of rotation of the wheel motor 231 is switched, and the bins 201 are moved to the position, which faces an original feeding/sending position, as each bin is held by the notch. At the original feeding/sending position, the originals are separated by a separation roller 215 from each other, one by one and are fed/sent to a copier side. When the prescribed feeding/ sending work is completed, the wheel motor 231 rotated in the reverse direction in order to rotate the Geneva wheel 207 in the opposite direction. Thus, the bin 201 for the original is guided toward an upper bin guide passage 220, so that the bin 201 can be forced to retreat in a shunt position. Next, the wheel motor 231 rotates in the reverse direction in order to make the notch of the Geneva wheel 207 face the lower bin guide passage 221, so that a next bin 201 for the original may be picked up. The similar operation continues thereafter.
