Abstract: A pressure-sensitive adhesive layer 3 is formed on a release treated surface of a release liner 4, and gas from holes 40 in the release liner 4 is made to move to the outside of the pressure-sensitive adhesive layer 3, thus forming through holes 31 in the pressure-sensitive adhesive layer 3. The pressure-sensitive adhesive layer 3 and a base material 2 having provided therein gas-passing channels that communicate to the outside of the pressure-sensitive adhesive sheet are then laminated together such that the gas-passing channels in the base material 2 and the through holes 31 in the pressure-sensitive adhesive layer 3 communicate with one another, thus obtaining a pressure-sensitive adhesive sheet 1. According to the pressure-sensitive adhesive sheet 1, air entrapment and blistering can be prevented or eliminated while securing adequate adhesive strength and with no marring of the appearance.

Abstract: A filtration device for use in filtering air used to purge a vapor storage canister used in connection with a fuel vapor recovery system of an automobile. The device includes a housing. In some instances, the housing may be integral to another component. The housing has a chamber having an arcuate inner surface. Air flowing into the chamber through an inlet port strikes the arcuate interior surface and is redirected such that the air rotates in said chamber. The centrifugal force of the rotating air filters out any contaminants of sufficient mass contained therein. The filtered air is removed via an outlet port positioned near the longitudinal-axis of the chamber. Contaminants removed from the air fall due to gravity or a secondary air flow pattern into a collection portion of the housing.

Abstract: Oleophobic and hydrophobic filters for filter venting applications are made by forming a polydimethylsiloxane coating on the surface of a filtration substrate. The filters have high water penetration pressures and high air permeabilities. The coatings are formed by polymerizing vinyl terminated siloxane with a crosslinker such as hydrosilicone in the presence of a catalyst. Alternatively, the coatings can be formed by heat curing after exposing the substrate to methyl silicone and crosslinking at high temperature.

Abstract: Carpeted panels comprising a thermoplastic substrate and a synthetic fiber carpet are produced by bonding the respective pads to one another using a vibration welding apparatus for causing the generation of frictional heat at the interface between the substrate and the carpet. One of the platen of the welding apparatus confronting the carpet is provided with a pattern of closely spaced pins engaging the carpet and urging the carpet into forced engagement with the substrate. On account of the closely spaced pins and the relatively low amplitude of the reciprocating motion, a bond is achieved substantially over the entire interface between the carpet and the substrate.

Abstract: A carriage for carrying a labeller, bundler or similar tool for working on sheet material spread on a supporting table is moveable vertically and transversely relative to such table by an associated lifting and transport cart allowing the carriage to be lifted from one table and transported to another table at which it is lowered onto the new table to bring it into working relationship therewith. The carriage may be engaged by the cart from the side or end of the table. Accordingly, the carriage may be moved from one table to another even in cases where the carriage can not be easily moved onto or off of the end of a table because of such table end being inaccessible. Means hold the carriage against vertical and lateral movement relative to the table while the carriage is in working relationship therewith, and these means are moveable to disengaged positions to free the carriage for vertical movement relative to the table when removing the carriage from or placing it onto the table.

Abstract: In the manufacture of a semiconductor device, e.g. a bipolar or MOS transistor, a narrow beam (4) of ions is deflected across a major surface of a semiconductor device body (1,2) to implant ions, e.g. a boron, into a region (3) of the body. In accordance with the invention a resist mask (5a) is obtained autoregistered with the implanted region (3) by effecting the implantation through a layer (5) of ion-sensitive resist thus exposed by the ion beam (4) in the area (5a) overlying the implanted region (3) at the same time as the implantation occurs into the body region (3). The non-exposed area of the layer (3) is afterwards removed by developing the resist, and the ion-exposed area (5a) is then used as a mask during a subsequent processing step, e.g. an etching or doping step, in the device manufacture. The implanted region (3) may be, e.g., a peripheral base region portion of a bipolar transistor or a parasitic-channel stopper below a field insulating layer (2) of an MOS integrated circuit.
