Abstract: The invention relates to a method of roughening glossy epoxy resin surfaces, particularly of circuit boards. In the more recent circuit board technology, circuit boards are coated with modified epoxy resin lacquers as a solder resist coating and as a protective coating. These coatings are mechanically very stable but result in high-gloss reflective surfaces. However, this light-reflecting surface interferes with the coating of such circuit boards. To this end, the invention provides for a process in which the circuit boards are fed through a spray module which sprays the circuit board on both sides with technically pure sulphuric acid. The method according to the invention is generally suitable for roughening glossy epoxy resin surfaces.

Abstract: In a device for releasing an odor-destroying substance into an air stream, such as for use with a kitchen exhaust hood, a refillable reservoir has an open side covered by a hood-shaped wall with flow openings through the wall. A cover disk extends over the hood-shaped wall on the opposite side from the reservoir for adjusting the flow openings, the hood-shaped wall affords a forced guidance of at least a part of the air stream past the open side of the reservoir.

Abstract: A bicycle seat according to the invention provides additional comfort for the rider. The seat (9) is made in two portions (10,11) which are mounted on a horizontal mounting member (15) so that they can be moved horizontally and will also have a limited rotational movement round the axis of the member (15). The shape of the top surface of the portions (10,11) is chosen to conform as much as possible to the shape of the human skeleton in the region of the ischium and upper femur. That of the top surface of the portion (11) is shown by graphs in Figures 8-10 of the drawings, and should not deviate by more than 20%. The shape of the portion (10) is a minor image of that of the portion (11).

Inventor: COCKRUM CHARLES A
IPC: H01L31/10
Filed: 1981-07-31
Abstract: Metallic contacts to compound semiconductor devices which employ a native oxide for passivation are provided. The metallic contacts of the invention comprise at least two metal layers: a first layer making non-rectifying contact with the semiconductor surface and providing a diffusion barrier and a second layer thereon comprising an easily oxidizable metal. A low resistivity metal layer may optionally be interposed between the two metal layers for improved conductivity. 
     The metallic contact is formed prior to passivation. The diffusion barrier layer prevents diffusion of potentially deleterious materials into the semiconductor, while exposed portions of the oxidizable metal form an insulating oxide during anodic passivation in an electrolyte. The insulating oxide prevents disruption of the electric field distribution in the electrolyte, thereby eliminating passivating oxide and device non-uniformities commonly encountered in the formation of prior art metallic contacts and providing more uniform semiconductor oxide thickness.

Abstract: In cathode ray tubes, less sharply limited, and irregularly distributed obstacles are fitted as inhomogeneities in or on the conical part of the wall of the tube. By this means, the development of an unavoidable implosion is influenced from the outset, in that crack formation is initiated at the inhomogeneities as a consequence of energy concentration in the case of the impact of shocks which endanger the tube. These cracks immediately propagate to the neck of the tube where they lead to a non-hazardous ventilation of the tube. <IMAGE>

Abstract: This invention relates to smoking articles having reduced free bum time, including cigarettes, cigars and little cigars. The smoking article comprises tobacco wrapped in a paper having at least one circumferential band printed between the ends of the smoking article; preferably at about the center of the smoking article. The band contains a substance which will cause the smoking article to extinguish in about 2-5 minutes under free bum conditions after the cone reaches the banded area if it is not puffed. The band is typically about 2-10 mm wide containing a substance which is a liquid in the temperature range of about 100°C to 200°C and which as the burning cone comes in contact with it provides a fluid film on the paper, without substantial penetrating through the surface of the paper, which film is substantially impervious to air and decomposes and/or distills endothermically from about 140°C to 300°C to yield gaseous decomposition products normally present in the smoke of smoking articles with the band. The amount of the substance used in the band should be sufficient to extinguish the smoking articles under free burn conditions within 2-5 minutes.

Abstract: The invention relates to a method and device for the manufacture of leaf springs made of fibre-reinforced material in the form of laminates, as well as leaf springs manufactured in such a manner. By means of the invention, the traditional production methods, which are protracted and complicated by the extensive manual tasks, are intended to be simplified. To this end, leaf springs (1a, 1b, 1c) are constructed of a plurality of at least partially hardened plates, forming individual laminate layers, e.g. laminate plates (2), between each of which is provided an adhesive layer (3, 2c, 2e). Thin, hardened laminate plates are preferably used as the plates; pre-preg layers as well as adhesive films can be used as the adhesive layers. Damping layers (4), e.g. of elastic-rubber material, can also be integrated in the layer arrangement. With a method according to the invention, leaf springs can be produced with good reproducibility in terms of their spring characteristics. <IMAGE>
