Abstract: METHOD OF PRODUCING A SEMICONDUCTOR DEVICE                  ABSTRACT OF THE DISCLOSURE      A semiconductor device of transistors, each of which is surrounded with a field oxide film, uses a dielectric isolation structure of a groove filled with an insulating material instead of a PN junction isolation structure.  The field oxide film is formed by selectively oxidizing an epitaxial layer, then the groove extending through the epitaxial layer and a buried layer is formed.          After the surface of the groove is covered with an insulating film, e.g., a thermal oxide film by oxidizing the surface, the groove is filled with the filler material.

Abstract: Abstract A vibratory particle separation apparatus of the type having a two plateau conveying surface interrupted by a drop-out opening.  A composite mixture is conveyed by a vibrating action beyond the upper plateau and over the drop-out opening.  An air supply is directed angu-larly in relationship to the plane of the upper plateau and breaks apart the composite mixture and propels par-ticles of a predetermined density and/or dimension to the landing area on the second level.  In another aspect of the invention, the landing area is adjustable angularly with respect to the plane of the upper plateau of the conveying surface and is translatable to constrict or enlarge the dimensions of the drop-out opening. The par-ticles passing through the drop-out opening and not in-tercepted by the landing area exit the system.

Abstract: ABSTRACT OF THE DISCLOSURE    By reacting a phenol compound with an organic halide selected from the group consisting of a haloform, a carbon tetrahalide and a substituted or unsubstituted allyl halide in the presence of an alkali metal hydroxide, using as a catalyst a fixed cyclodextrin having hydroxyl groups crosslinked with a bivalent hydro-carbon group having free valences at its both ends, said hydrocarbon group having at least one hydrogen atom substituted or unsubstituted with a member selected from the group consisting of an alkyl group, a halogen atom and a hydroxyl group and containing or not containing at least one combination of two neighboring carbon atoms having therebetween at least one member selected from the group consisting of an oxygen atom, a sulfur atom and a phenylene, various useful para-substituted phenol derivatives can be advantageously obtained.  The fixed cyclodextrin which has been used as the catalyst can be extremely easily separated from the reaction system without any loss of the fixed cyclodextrin, and the recovered fixed cyclodextrin can be used repeatedly as a catalyst in the process of the present invention without lowering in yield of and selectivity for para-substituted phenol derivatives.

Abstract: Abstract of the Disclosure There is disclosed a composite label web and method of labeling.  The composite label web has a flexible, longitudinally extending carrier web with cuts to provide feed registration, flexible labels carried on the carrier web, non-tacky adhesive releasably adhering the labels at their undersides to the carrier web, a longitudinally extending line of weakening spaced between side edges of the labels and dividing the labels into detachably connected first and second label parts, pressure sensitive adhesive on the outer sides of the first label parts, and flexible masking material adhered to and masking off the pressure sensitive adhesive on the first label parts.  The disclosed method can be practiced using a hand-held labeler which effects printing on the second label parts, effects separation of the labels from the carrier web at its delaminator and dispenses the labels.  When the masking material is removed, the first label part can be adhered to the underside of a marginal side edge of a tag.

Abstract: GAS TURBINE ENGINE AUGMENTOR  ABSTRACT OF THE DISCLOSURE         A new and improved gas turbine engine augmentor including a liner having a film-coolable first portion joined to a convention-coolable second portion is disclosed.  A cooling gas, such as fan bypass air, is channeled to the liner for the film cooling the first portion and providing a residual cooling film to the second portion.  The second portion is also convention coolable by air passing over an outer surface thereof.  In a particular embodiment of the invention, the augmentor liner also includes a screech portion disposed at an upstream end of the first portion and downstream of a flameholder. The screech portion includes a substantially imperforate outer wall and an inner wall spaced therefrom which define a manifold therebetween.  The inner wall includes a plurality of apertures in flow communication with the combustion zone.  The manifold and apertures are effective for suppressing screech while substantially preventing the leakage of cooling air therethrough.
