摘要:
The invention relates to an arrangement of contact areas and test areas on patterned semiconductor chips. The contact areas and the test areas are electrically connected to one another via a conduction web. Whereas the contact areas are arranged in a first region, which has no components of an integrated circuit, the test areas lie in a second region of the top side of the semiconductor chip, which region has components of an integrated circuit.

A description is given of a heat-sensitive recording material comprising: a sheetlike carrier; a thermoreactive layer on at least one side of the sheetlike carrier; and an interlayer, formed between the sheetlike carrier and the respective thermoreactive layer, which comprises hollow-sphere pigments embedded in a binder; and also, if appropriate, comprising top layers and/or further layers. This recording material is characterized in that the hollow-sphere pigments take the form of a composite pigment, with nanoscale pigment particles attached to the surface of an organic hollow-sphere pigment. This material can be produced inexpensively at high operating speed. The interlayers that are proposed in accordance with the invention exhibit optimum insulation capacity. They also have the effect of reducing or preventing the unwanted phenomenon of the text showing through, particularly when the thermoreactive layers are formed on both sides of the sheetlike carrier. The recording material exhibits a high optical density, runs very well in the thermal printer, in particular without depositing on or sticking to the thermal printing head in application, and the thermal print exhibits a homogeneous appearance.
摘要:
A spray nozzle assembly for atomizing a medium through a nozzle channel, comprising a first channel portion which is tapered by two lateral surfaces facing each other to form an elongate narrow cross-sectioned surface, a passage orifice disposed in the narrow cross-sectioned surface the cross-sectional area of which is smaller than is the narrow cross-sectioned surface, and a second channel portion adjoining the passage orifice in the direction of medium flow which has two opposed lateral surfaces separating from each other with an increase in distance from the passage orifice, whose edges facing the passage orifice extend crosswise to the longitudinal direction of the narrow cross-sectioned surface, characterized in that the nozzle channel having the two channel portions and the passage orifice are configured inside an integrally formed plastic component.

The present invention relates to the coating of tubes, and more particularly to a system and method for renovating deteriorated or pitted tubes to extend tube life and enhance performance. Using this system and method a thin coating is applied to the interior of a tube such that the coating is uniform in thickness, spans existing erosion elements or cracks within the inner surface of the tube and covers all regions of the tube.

A feeding valve having a hose coupling in the form of an expansion bellows which unfolds automatically into the wearer's field of vision when the sealing cap of the feeding valve is opened, thereby enables a wearer to easily insert the straw of a food or beverage bottle even when wearing protective gloves.
摘要:
A composition comprising at least one organofluorine-functional silane and/or siloxane, at least one mineral acid and at least one metal salt of aluminum(III), tin(II), tin(IV), iron(III) or titanium(III); a process for preparing said composition and to its use; and surface-modified substrates obtainable by coating with said composition.
摘要:
Fluoroalkyl organosilicon compounds are prepared by reacting fluoroolefins with organosilicon compounds that contain at least one H-Si group, in the presence of a Pt(0) complex catalyst. Further, fluoroalkylalkoxy organosilicon compounds are prepared by esterifying fluoroalkyl organosilicon compounds. The process proceeds uniformly under mild conditions with high yields and selectivities.
摘要:
The present invention relates to a stable composition of water-soluble organosiloxanes obtained by reacting a) a water-soluble amino-functional alkoxysilane with at least one water-insoluble alkenyl-functional alkoxysilane b) by adding water to form a mixture, and c) removing the alcohol formed during step b) from the mixture, where the amino-functional alkoxysilane and the water are used in the reaction at least in amounts such that substantially all of the alkoxy groups of the water-insoluble silane can react and such that when a resulting composition is diluted with water, essentially no alcohol is liberated by hydrolysis, and the composition, during an/or after the reaction, has a pH of from 2 to 6, the pH being preferably adjusted by adding an organic or inorganic, optionally aqueous, acid. In addition, the present invention discloses a process for the preparation of such a composition and also its use.
