Abstract: Starting from a mixture of at least a hydrophobic polymer and a hydrophilic polymer, these polymers are first dissoved in a suitable solvent or mixture of solvents and subsequently coagulated in a coagulation bath. According to the invention a more or less hydrophilic membrane is prepared by removing the membrane so obtained from the coagulation bath and subsequently by leaching at least a part of the hydrophilic polymer from the matrix, alternatively followed by hydrophobisation. Said leaching of the hydrophilic polymer occurs by treatment of the membrane with an oxidising/hydrolising agent. The invention furthermore comprises microporous membranes, flat or tubular or in the form of hollow fibers, having a good chemical resistance and good mechanical strength.

Abstract: PURPOSE:To remove stain produced at the time of mounting and avoid shortcircuiting, by providing a processed layer having high etching speed on the surface of an element prior to the mounting of a composite semiconductor element on a stem by means of waxing, and operating etching after the mounting. CONSTITUTION:Si pellets 1, in which PN junction is formed, are laminated by using wax 2, and thereby composite semiconductor element 3 is formed. Next, the exposed surface of element 3, after being etched, is fixed to Au-plated stem 4, which is to become a lower electrode, by using Au-Si eutectic metallic wax 5. On its upper part is fitted upper electrode 6 by using wax 5 again. When this is done, the PN junction may likely be shortcircuited by a flow of wax 5 as the wetting with respect to wax 5 on the element surface has increased due to the etching before the mounting. For this reason, layer 7, such as a processed or diffused layer, having high etching speed, is provided on the surface of element 3 before the mounting, and after the mounting, layer 7, together with unwanted wax 5, is removed, and thereby the surface is cleaned.

Abstract: PURPOSE:To strengthen the junction between a lead frame and an Al wire, and to reduce secular degradation by forming an electric Ni plated film having not more than 0.5mum roughness onto the lead frame. CONSTITUTION:When an Al wire is joined onto an Ni plated film, difference is generated in shearing strength according to the difference of the roughness of the Ni plated film, and the more the surface is rough, the more a junction rate lowers. With the electrically plated Ni film, roughness is far smaller than a chemically plated film and approximately 0.1-0.3mum, and scatter is small. The rate of phosphorus and a brightener in the plated film is increased, and the roughness of the surface of the film is decreased and made 0.5mum or less. According to this constitution, the Al wire junction with a strong joined section is obtained while the secular degradation is also reduced, and the reliability of the device is improved.

Abstract: In a vertical MOSFET, an inactive ion species is ion-implanted into a J-FET portion, a surface channel layer, and/or a base region. The inactive ion species fill intrinsic carbon vacancies or interact with interstitial Si atoms, which are possible origin or responsible for B-diffusion from the base region. Accordingly, the B-diffusion caused by the intrinsic carbon vacancies when the base region is formed is suppressed. The width of the J-FET portion is prevented from being decreased, thereby preventing an increase in resistance of the J-FET portion. Also, the conductive type of the surface channel layer is prevented from being inverted by diffused impurities.

Abstract: The ratio of silane-to-ammonia in a reaction designed to deposit a silicon nitride thin film affects the refractive index as well as the absorption coefficient of the film. By controlling the influx of these gases such that an essentially small ratio of silane-to-ammonia exists in a reaction chamber, a silicon nitride film (9) is deposited which is transparent to ultraviolet radiation 4. The exact ratio needed is dependent upon the geometry and operating parameters of the reaction chamber system employed in the deposition process. Ultraviolet light transparent silicon nitride film provides a superior passivation layer (9) for erasable programmable read only memory integrated devices (2).

Abstract: A method for producing a leno or cross weaving texture in which, alternatingly with successive weft insertions, a first warp thread, also said "crossing-thread" (4), gets crossed with at least one second warp thread on the one side and on the other one side relatively to said at least one second warp thread, also said "stationary-thread" (7), with said crossing-thread being moved both transversely and perpendicularly to the weaving plane (C), and said stationary-thread being only moved perpendicularly to the weaving plane.

Abstract: A method and apparatus (10) for selectively sintering a layer of powder to produce a part comprising a plurality of sintered layers. The apparatus includes a computer (40) controlling a laser (12) to direct the laser energy onto the powder to produce a sintered mass. The computer either determines or is programmed with the boundaries of the desired cross-sectional regions of the part. For each cross-section, the aim of the laser beam is scanned over a layer of powder and the beam is switched on to sinter only the powder within the boundaries of the cross-section. Powder is applied and successive layers sintered until a completed part is formed. The powder may consist of a plastic, metal, ceramic, or polymer substance. In the preferred embodiment, the aim of the laser is directed in a continuous raster scan and the laser turned on when the beam is aimed within the boundaries of the particular cross-section being formed. Preferably, the powder dispensing mechanism includes a drum which is moved horizontally across the target area and counter-rotated to smooth and distribute the powder in an even layer across the target area. A downdraft system provides controlled temperature air flow through the target area to moderate powder temperature during sintering. <IMAGE>
