Abstract: ABSTRACT The invention relates to a method of making collagen gel suitable for use in the manufacture of thin collagen film articles having superior mechanical properties comprising:  providing clean animal tendon at room tem-perature containing at least 30% collagen essentially free of ligamentous tissue; comminuting said tendon and processing it once through a microcutter in the presence of about 65% water by weight to form a collagen slurry; treating said slurry with about 0.1 - 0.5% by weight Rhozyme - 41 based on collagen solids content of said slurry to digest elastin and other non-collagenous matter while leaving the collagen structure substantially intact; acid-swelling the slurry with an acid selected from the group consisting of lactic acid, maleic acid, succinic acid, malic acid, oxalic acid and tartaric acid to form a swollen collagen suspension; homogenizing and deaerating said suspension to form a collagen gel.  The invention further relates to the collagen gel so obtained, film articles made therefrom and a method of making the film articles. The collagen gel so obtained is more homogeneous and imparts improved thinness, smoothness and strength to articles made therefrom.

Abstract: LIGHT REFLECTING THREE-DIMENSIONAL DISPLAY SYSTEM     ABSTRACT OF THE DISCLOSURE A display system (10) receives from a light source (12) a sequence of images, each representing a different depth plane of a subject, and selectively reflects each image from its corresponding one of plural light direction modulators (16 and 18) to synthesize a three-dimensional image of the subject.  Each modulator is positioned along an axis (20) at a location that corresponds to a different depth plane.  Each modulator reflects the first image incident to it and transmits the succeeding images in the sequence.  In a display system having N+l depth plane images, each of N modulators comprises a variable optical retarder (34) and a liquid crystal chiral cell (36).  The N modulators reflect left-circularly polarized light and transmit right-circularly polarized light.  An N+l modulator preferably comprises a liquid crystal chiral cell and reflects light incident to it.  An alternative embodiment (50) develops full color images.

Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a semiconductor device of over-voltage self-protection type which is safely turned on in response to application of an overvoltage exceeding a breakdown voltage.  When, after formation of a pre-determined pn junction in a semiconductor substrate, an etched region is formed in a cathode-side base layer from the side of a cathode emitter layer, the breakdown voltage is variable depending on not only the depth but also the diameter of the etched region.  Noting the above fact, a circular overvoltage self-protection region having a depth d and a diameter D is provided together with a slot-like turn-on current limiting region having the same depth d but a width smaller than the diameter D of the circular region.  The turn-on current limiting region is disposed between the overvoltage self-prevention region and the cathode emitter layer.
