Abstract: A low cost thermoplastic material having a low heat distortion (HDT) thermoplastic material forms the main structural component of a structural member. A relatively high cost high HDT thermoplastic material is attached to the low cost main structural component and is plated with a solderable metallic coating. The coating can be attached to other structures with relatively higher temperature molten solder with negligible distortion. The structural member may be, for example, an electrical shield to be soldered to a printed circuit board or a printed circuit board whose core is low HDT material and exterior is high HDT material.
Abstract: A transparent laminated window structure having high impact resistance is disclosed, wherein the window comprises a continuous inner layer of thermoplastic material, and an outer layer substantially parallel to the inner layer including at least a first course of discrete, mutually spaced glass segments, the spaces between adjacent segments containing an adhesive material. The window structure may further comprise a strip of elastomeric material compressed between the inner and outer layers so as to define a gas gap between the layers. A projectile contacting a particular glass segment in the outer layer will fracture that segment, but will not cause cracking in the adjacent, mutually spaced segments in the same course, and therefore, a high degree of visibility through the window structure will be retained after impact by the projectile.
Abstract: A printed wiring board comprising a plastic material is formed with a through opening for mounting electronic parts therein, and the end of the opening on the rear side of the board is closed by a metal sheet bonded to the area around the opening end on the rear of the board through an adhesive layer. The inside wall and bottom face of the opening in the board are coated with an integral plating film as are the rear surfaces of the board an metal sheet. According to this board structure, the heat generated from electronic parts mounted on the bottom of the opening is dispersed by the metal sheet, and also penetration of moisture into the opening through the plastic material and the adhesive layer, as occurs with conventional boards, is prevented by the plating film.

Abstract: Solid, transparent, non-vitreous, zirconia and zirconia-silica ceramic microspheres, useful as lens elements in retroreflective pavement markings. The microspheres are characterized by:(a) containing at least one additive metal oxide selected from alumina, magnesia, yttria and mixtures thereof;(b) an index of refraction greater than 1.6; and(c) being virtually free of cracks.These microspheres are formed by a sol-gel technique of extractive gelation (extracting carboxylic acid away from zirconyl carboxylate) of a sol in liquid medium such as hot peanut oil. The microspheres of this ceramic composition have been made with relatively large diameters, (e.g. 200-1000 micrometers) making them quite useful as lens elements in pavement marking sheet materials.

Abstract: A molded polyolefin container for hydrocarbons having improved barrier to permeation of fluid hydrocarbons through the walls of the container is disclosed. The container walls comprise from 0.1% to 2% by weight of aluminum powder in the polyolefin container walls. The aluminum powder is substantially uniformly distributed throughout the polyolefin container walls. The polyolefin may be polyprolylene or polyethylene. This type of container provides an economical packaging system for hydrocarbons compared to existing packages of metal or polyvinylchloride.
Abstract: Disclosed is a method of forming a hard, carbonaceous film on a substrate and the hard carbonaceous film formed thereby. The hard carbonaceous film is formed by decomposing a gaseous hydrocarbon having carbon atoms tetrahedrally coordinated to its nearest neighbors through carbon-carbon single bonds. The gaseous hydrocarbon is decomposed in a radio frequency maintained plasma and the plasma decomposition products are deposited on a cathodic substrate. Optionally, fluorocarbons may be present in a decomposition gas.
Abstract: An ink jet recording medium having at least one ink receptive layer containing synthetic silica of fine particle form as a main pigment, having a recording surface dried by pressing said recording surface against a heated mirror surface, and having ink receptive layer having an absorption capacity of at least 10 g/m.sup.2 is disclosed.That is, the present invention provides an ink jet recording medium which has a gloss without requiring any post-treatment for imparting the gloss, has a high ink absorbability and gives a high color reproducibility and a high color density in printing with a water-base ink, particularly a recording medium for full color ink jet recording having a gloss.
Abstract: Improved binders or binding seals are proposed which have a substrate of a flexible material. At one end of the substrate is provided an ordinary adhesive layer and at the other end is provided a peelable adhesive layer covered with an ordinary adhesive layer. The peelable adhesive layer allows the user to stick the end of the binder and peel it whenever desired. The binder may be formed with a hole or holes at one end to secure it to a file, and with a peelable adhesive layer at the other end so that a document can be stuck and peeled on and from it.
Abstract: For higher thermal conductivity, stronger adhesion strength, excellent insulating characteristics, and multilayer interconnection, an aluminium sintered body for circuit substrates comprises a novel conductive metallized layer on the surface of the sintered body. The metallized layer comprises at least one element selected from the first group of Mo, W and Ta and at least one element selected from the second group of IIa, III, IVa group elements, lanthanide elements, and actinide elements in the periodic table, as the conductive phase element. The first group element serves to improve the heat conductivity and resistance, while the second group serves to increase the wetness and adhesion strength between the insulating body and the metallized layer. Further, the plural insulating ceramic bodies and the plural metallized conductive layers can be sintered simultaneously being stacked one above the other to permit a multilayer interconnection.

Abstract: An article of manufacture includes a substrate carrying at least two coating layers, one layer being of approximately quarter wave optical thickness, the other layer of approximately two quarter wave optical thickness, with the layers alternating between a material such as a dielectric having a first index of refraction and a second material such as a dielectric having a second index of refraction lower than the first index of refraction. These layers form a filtering system which removes narrow bands of light such as laser wavelengths by efficient reflection while permitting the remainder of the light spectrum to pass through the article. The coating layers have optical thicknesses and indices of refraction appropriate to reflect more than 99% of incident light at one or more predetermined wavelengths of light in the range of about 300 to about 1,200 nanometers and to transmit a substantial amount of all other incident light in the range.
