Title: Unidirectional variable magnification duplicating method
Inventor: IKOMA AKIRA
IPC: G03B27/34
Filed: 1979-09-21
Abstract: PURPOSE:To equalize the moving speed of an image in a slit exposure part to the speed of slit exposure, by increasing or decreasing sine ratio of the angle of exposure luminous flux to an original surface to that to a photoreceptor from 1 by a value that corresponds to the rate of magnification variation. CONSTITUTION:This method, when the copying magnification is denoted as (m) (>=1 or <1), varies the copying magnification only in longitudinal direction (alpha) parallel to the slit exposure direction or perpendicular lateral direction (beta) to m+ or -DELTAm. For magnification variation in longitudinal direction (alpha), the optical exposure system consisting of reflex mirrors 21, 22 and 24 is applied with the arrangement for duplication of (m) in copying magnification, the slit exposure speed of a photoreceptor is set for copying magnification m+ or -DELTAm, and the sine rate of the angle of exposure light flux to the original surface to that to the photoreceptor is increased or decreased from 1 by a value that corresponds to the rate + or -DELTAm of magnification variation, thereby equalizing the moving speed of an image in the slit exposure part to that of slit exposure. For magnification variation in lateral direction (beta), duplication is carried out similarly.

IPC: C22C5/06
Filed: 1992-04-15
Abstract: PURPOSE:To provide the method for manufacturing a silver thin sheet used as an electrical contact material or the like. CONSTITUTION:A silver ingot constituted of 20 to 100ppm Cu, and the balance Ag with inevitable impurities is prepd. This silver ingot is subjected to cold rolling to manufacture a silver thin sheet. At this time, the silver ingot or silver sheet in the process of the cold rolling is heated to 550 to 900 deg.C. The heated silver ingot or silver sheet is cooled by water. In particular, the draft in the cold rolling is preferably regulated to 50 to 95%. Even if the silver thin sheet immediately after the manufacture or after being allowed to stand for a long term is exposed to a high temp. of about >=2800 deg.C, the coarsening of the crystalline grains in the silver thin sheet is hard to generate. Thus, by using this silver thin sheet, the effects that cracks on the silver thin sheet are difficult to generate and roughening on its surface is hard to generate even if being exposed to a high temp. are given. Furthermore, the effects that the softening of the silver thin sheet is difficult to generate and the deterioration in its quality is small even if being allowed to stand for a long term after the manufacture are obtained.
