Abstract: A reflecting warp-knit slide fastener tape is knitted with several kinds of knitting patterns. A marginal portion onto which fastener elements are attached extends along one longitudinal edge of the tape. The marginal portion is formed by tricot-stitch yarns, weft-inlaid yarns, and chain-stitch yarns which prevent the marginal portion from stretching. In the web portion, in addition to the tricot-stitch yarns and the weft-inlaid yarns one or more reflective members, which is in the form of a strip of retroreflective or light-reserve reflective film, are knitted in between wales contiguous to the marginal portion. The reflective members are sandwiched between the weft-inlaid and tricot-stitch yarns. The tricot-stitch yarns are transparent synthetic fiber yarns in order not to obstruct the reflecting feature of the reflective members.

Abstract: The present invention relates to a recording material for the inkjet method with aqueous inks, having at least one temporary substrate material and a porous ink absorption layer which is applied thereon, can be converted into a film and comprises from 60% by weight to 95% by weight of thermoplastic particles having a mean particle size between 1 &mgr;m and 40 &mgr;m, preferably from 5 to 20 &mgr;m, and 5-40% by weight of film-forming binder and, if required, conventional assistants and additives. After conversion of the recording layer into a self-supporting cohesive film by the action of heat and, if required, pressure, said film can be removed from the temporary substrate material at room temperature with a separation force of 10 cN/50 mm strip width to 800 cN/55 mm. In the case of further intermediate layers, the least adhesion of the laminated layers between one another in the laminate is that between temporary substrate material and adjacent layer.

Abstract: Processed plant fine fibers such as those from the mesocarp of a coconut together are blended with a biodegradable plastic to produce a biodegradable plastic product that can be further made into other items. Plastics thus made from coconut husk fine fiber powder will return to the environment after disposal much more rapidly than those without coconut husk fine fiber powder. In the process, a dry compressed plant fine fiber powder is created from fine fibers of the coconut mesocarp. An example product created from this raw material is composed of 10 to 40% by weight of dry coconut husk powder mixed with environmentally degradable plastic. Environmentally non-degradable plastic may be added to the dry powder as a biodegradation rate modulator to create a modified raw material with a modified biodegradation rate. Plastic additives, standard in the industry, can be added to achieve additional desired properties.

The overcoating layer is formed from a mixture of a water-insoluble polyvinyl acetal resin, fine particles of an acrylic resin and a polyvinyl pyrrolidone.

Abstract: A high speed data transmission cable comprises a pair of primary cables positioned adjacent to each other along their lengths with each primary cable including a pair of generally parallel conductors coupled together and surrounded by insulation. A shield layer surrounds each primary cable along its length to isolate the primary cables from each other. The primary cables and corresponding shield layers are twisted together around a center axis and form a double helical structure, thereby providing improved transmission characteristics in the high speed data transmission cable.

Abstract: A color changeable device that has been partially activated. The device comprises a flexible substrate with a first major surface and a second major surface and an interference color generating laminate on the first major surface. The color generating laminate comprises a first layer and a second layer in intimate contact. When the first and second layers are in intimate contact, the laminate generates an interference color. When the first and second layers are not in intimate contact, the laminate does not generate the interference color. The substrate and laminate include a first permanent deformation causing separation of the first and second layers at a first portion of the device while retaining the first and second layers in intimate contact at a second portion of the device. The device is particularly useful for confirming the authenticity of an article without having to remove the color change device from the article.

The aluminum-containing layer is disposed below a photoresist mask having a pattern thereon. The method includes providing a plasma processing chamber and positioning the substrate having thereon the layer stack, including the aluminum containing layer and the photoresist mask, within the plasma processing chamber. The method further includes flowing an etchant source gas that comprises HCl, a chlorine-containing source gas, and an oxygen-containing source gas into the plasma processing chamber. The flow rate of the oxygen-containing source gas is less than about 20 percent of a total flow rate of the etchant source gas. There is also included striking a plasma out of the etchant source gas, wherein the plasma is employed to etch at least partially through the aluminum-containing layer.

Abstract: There is provided an integrated semiconductor processing apparatus which produces less dust. The apparatus comprises a reaction chamber, a boat means, a motor, and a sealing mechanism. The sealing mechanism includes a movable sealing means which serves as a non-contact seal when a wafer is being rotated and which serves as a contact seal when the wafer is static. The movable sealing means is an expandable elastic seal comprising an expandable elastic member. By increasing the pressure inside the expandable elastic seal, the surface of the elastic seal is put in contact with a rotating shaft to achieve perfect sealing. The internal pressure of the expandable elastic seal can be adjusted to control the contact and non-contact state of the seal. The apparatus according to the invention suppresses generation of dust in all steps of etching to improve production yield.

Abstract: Multiple sheets spiral bound together as a unit by a continuous filament. The sheets have a plurality of closely spaced perforations aligned along an edge thereof. The filament is an elongated rod-like member having an outer surface and a centrally-located longitudinal axis. The filament is flexible and is disposed in spiral configuration through the perforations. The filament additionally comprises an inner surface defined by an internal elongate passage extending therethrough. The internal opening facilitates crimping of the inventive filament after it has been spiraled into a plurality of closely spaced perforations aligned along an edge of a stack of sheets. The internal opening in the filament also provides improved control over the outer dimension of the filament during manufacture.
