    Abstract: A pharmaceutical composition containing an extract from inflammatory tissue inoculated with vaccinia virus may be used to suppress the death of cells caused by endotoxin, and suppress excessive production of nitrogen monoxide induced by endotoxin. The extract may also be used to relieve hypotension induced by endotoxin. In sepsis and other serious bacterial infectious diseases, endotoxin (an intracellular toxin) is produced and a shock symptom is induced by its action. The extract, having an excellent inhibitory action toward endotoxin-induced toxicity, is quite useful for the treatment or the prevention of endotoxin-induced shock symptoms, sepsis and various symptoms accompanied thereby. In addition, the extract has an inhibitory action towards abnormal nitrogen monoxide production during the diseased state and, therefore, it is also useful as a therapeutic and preventive agent for diseases wherein an excessive nitrogen monoxide production occurs, such as acute hypotension.

  • Patent number: 4721992
    Abstract: In an assembly tape to be used in the tape automated bonding of semiconductor devices a single layer or two or three layer tape is described. The arrays of finger patterns created in the tape are isolated by forming transverse slots across the tape. These slots act to mechanically isolate adjacent finger patterns and improve tape flexibility. When the tape is passed under the guide shoe in an inner lead bonding machine the metal fingers will not be distorted as the tape flexes. After the semiconductor device is bonded to the tape the increased tape stiffness does not cause the tape to be deflected from its desired location with respect to the guide shoe. The slots desirably span the space between tape locator holes. If desired, the slots can be extended on the finger side of the tape to span the locator holes to form slot extension regions of reduced tape thickness. Alternatively, a slot can be formed from a plurality of shorter slots that in the aggregate perform the same function.

  • Patent number: 4710062
    Abstract: A rolled metal strip for use in stabilized earth structures has at periodic intervals along its length thickened reinforcement regions formed during the rolling operation. The strip is cut into required lengths such that each strip length has an end reinforced region through which an aperture is then formed to receive a bolt passing through a bracket of a facing. The strip may include transverse ribs at intervals on both faces of the strip to assist engagement with the surrounding soil.

  • Patent number: 4701363
    Abstract: A process for step etching a metal tape adapted for use in tape automated bonding comprises forming an etch resist pattern on the tape having a first portion defining a pattern of leads and a second portion within the first portion defining steps in the leads. The metal tape is etched in the regions not covered by the resist at a desired rate and etched in the regions for forming the step at a reduced rate as compared to the desired rate, thereby forming the tape having a plurality of leads corresponding to the resist pattern with each of the leads having a step therein generated by the second portion of the resist pattern. The metal tape formed by the process has a unique structure wherein the web between bumps formed at the end of the leads and the remainder of the leads has a unique channel beam cross section for stiffening the web which is relatively thin as compared to the leads or the bump.

  • Patent number: 4597146
    Abstract: An improved method of making lead or tin based alloy badges or emblems having brilliantly colored closely spaced cloisonned areas into which the desired colors can be introduced. The cloisonned areas separate the differently colored sections from each other by the formation of slight ridges or low fences into which the differently colored paints can be introduced. After the differently colored paints or other colorings have been introduced into the cloisonned areas and dried, the badge or emblem is polished to expose the ridges or fences separating the cloisonned areas and any other raised areas which it is desired to emphasize. The badge or emblem is then plated with an appropriate plating to cover the raised cloisonned areas and any other raised areas which it is desired to highlight. The resulting badges or emblems have clearly defined brilliantly colored sections and embody remarkable detailed structures.

  • Patent number: 4456500
    Abstract: In a method of making a polishing element a photoresist film 2 is first deposited on a surface of metal stock 1. A photomask 3 is then used to selectively cover portions of the deposited photoresist film 2. Thereafter, portions of the photoresist film 2 which are not covered by the photomask 3 are removed in order to leave exposed patterned portions 5 of the metal stock surface. Gulf-shaped recesses 6 are then etched into the exposed portions of the metal stock surface. The formation of gulf-shaped recesses 6 results from the application of a etchant while the metal stock 1 and the etchant are in physical motion relative to one another. After etching, remaining portions of the photoresist film 2 are removed from the metal stock. A polishing element 10 comprising cutting teeth 11 having acute cutting action angles results.

  • Patent number: 4404264
    Abstract: An improved method and apparatus for the production of multi-gauge strip is disclosed wherein the multi-gauge strip comprises a first strip of metal having a first thickness and extending longitudinally for a given length. A second strip of metal has a second thickness, is narrower in width than the first strip, and coextends longitudinally with the first strip of metal. The first and second strips of metal are intimately bonded in direct metal-to-metal contact without the use of a welding or brazing material. The multi-gauge strip has a first portion extending the given length with a third thickness substantially equal to the sum of the first and second thicknesses and a second portion of substantially constant width extending the given length having a fourth thickness substantially equal to the first thickness.
