    摘要: A three-dimensional image is produced using an imaging medium having a lenticular screen, the lenticles of the screen dividing the opposed surface of the imaging medium into a plurality of elongate image areas, the imaging medium having on the opposed side thereof a radiation-sensitive layer, the radiation-sensitive layer comprising a color-forming composition adapted to undergo a change of color upon increase in the temperature of the radiation-sensitive layer above a color-forming temperature for a color-forming time. The radiation-sensitive layer is imagewise exposed to actinic radiation which does not pass through the lenticular screen, thereby causing the color-forming composition to undergo its change in color in exposed areas and to form in the radiation-sensitive layer a composite image, the composite image comprising, in each of the image areas, a plurality of image strips extending lengthwise along the image area, each of the image strips containing information from a view of the object, each of the plurality of image strips in one image area containing information from a different view of the object thereby forming a copy of the composite image in the radiation-sensitive layer, so that a three-dimensional orthoscopic image of the object will appear to an observer seeing the composite image in the radiation-sensitive layer through the lenticular screen.

    摘要: A centrifugal impact atomization process for producing zinc or zinc alloy powder from molten zinc. A stream of molten zinc is injected onto the surface of a spinning disk contained within an atomization chamber. The disk has a cup shaped cavity having an open end, opposing closed end and integral side walls. The disk may have baffles protruding into the open cavity core within the disk. The baffles may have straight or curved side surfaces. The disk is rotated at high speeds between about 10,000 and 15,000 rpm (revolutions per minute). The oxygen content in the chamber is preferably between about 1 and 6 vol %. Zinc powder is produced having more smaller size particles. Zinc alkaline cells utilizing such zinc product as anode active material show improved performance, especially as power source in high discharge services such as digital cameras.

    摘要: An imaging medium capable of being imaged to form a transparency comprises a substantially transparent support having a thickness of at least about 20 .mu.m, a color-forming layer superposed on the support and comprising a color-forming composition adapted to undergo a change of color upon increase in the temperature of the color-forming layer above a color-forming temperature for a color-forming time; and a bubble-suppressant layer superposed on the color-forming layer and having a thickness of at least about 10 .mu.m. Upon imagewise increase in the temperature of the color-forming layer above the color-forming temperature for the color-forming time, in heated regions the color-forming layer undergoes its change of color but remains essentially free from bubbles, thereby providing an image in which the colored regions are not blackened when viewed in transmission.
