Patent EP-0278854-A2 (EP)
Inventor: INOUE YOSHIO
IPC: C08L101/02
Filed: 1988-02-01
Abstract: The curable and foamable organopolysiloxane composition comprises three different organopolysiloxanes, of which (A) the first is an α,ω-divinyl dimethyl polysiloxane, (B) the second is an organopolysiloxane having, in a molecule, at least three silicon-­bonded hydroxy groups and (C) the third is an organohydrogen­polysiloxane having, in a molecule, at least two silicon-bonded hy­drogen atoms, along with a platinum catalyst. The platinum-cata­lyzed curing and foaming reactions proceed in two ways of, one, the hydrosilation between the vinyl groups in (A) and the silicon-bond­ed hydrogen atoms in (C) and, the other, by the dehydrogenation between the silanol groups in (B) and the silicon-bonded hydrogen atoms in (C). The composition gives a cured and foamed silicone rubber body having excellent mechanical properties with a good cell structure by standing at room temperature or by heating up to 70°C.

Abstract: A photosensitive resin composition for producing a relief printing plate is disclosed, which comprises a poly­mer selected from the group consisting of a prepolymer, a binder polymer and a mixture thereof, an ethylenically unsaturated monomer, a specific hindered amine and a photo­polymerization initiator. Even when the photosensitive resin composition is excessively irradiated with strong actinic rays in order to cure the resin composition to its inner portion sufficiently, the surface of the resin com­position does not undergo photodeterioration by virtue of the hindered amine contained therein, thereby imparting excellent toughness to the photocured resin composition throughout the entire thickness thereof. Thus, a relief printing plate having excellent printing resistance can be produced.

Abstract: The present invention relates to a method for making shaped parts or objects for motor vehicles, in which method a web of polymer melt emerging from a slot-die extruder or a similar plasticising device is used for the female forming process. In this method, the surface of the web of polymer melt facing away from the deep-drawing mould is subjected to a precooling, so that a self-supporting melt skin already forms on the surface facing away from the deep-drawing mould immediately after discharge from the extruder. A temperature difference of more than 30 K is set between the temperature of the web of polymer melt and the colder deep-drawing mould, and the web of polymer melt is passed through an at least two-part mould, is clamped, held and/or sealed off and separated as well as being moulded using the deep-drawing mould and a pressure difference, the web of melt taking on the microporous, grained, textured, shaped and/or surface-decorated form of the deep-drawing mould and immediately cooled or shock-cooled by more than 70 K.

Abstract: A TFT is fabricated by providing on a substrate (10), and over a gate (12), a sequentially formed multi-layer structure consisting of a gate insulator layer (14), an intrinsic semiconductor, e.g. a-Si or polysilicon, layer (16) for the channel, a doped semiconductor, e.g. n type a-Si or polysilicon, layer (18) for source and drain contact regions and a passivating layer (20). The layer (18) extends completely over and covers the channel region of the layer (16). Thereafter, the portion (30) of layer (18) overlying the channel region is converted by a compensating doping implant to a highly resistive form separating the source and drain contact regions, and windows (22, 24) are defined in the passivating layer (20) into which source and drain contacts (26, 28) are deposited. In this way critical interfaces are protected from contamination. 
     The TFT is suitable for use as a switching element in active matrix display devices, e.g. LC-TVs.

Abstract: A light source (140) is responsive to an input electrical signal (172) to increase or decrease its output depending upon whether the input electrical signal (172) corresponds to a higher light output level than the source (140) is currently providing or a lower light output level than the source (140) is currently providing, respectively. The output control comprises a light detector (146) for monitoring the light output and for producing a signal related thereto, a voltage source (156, 157) for establishing a maximum desired light output, a voltage source (158, 159) for establishing a minimum desired light output, and a window comparator (152, 154) for comparing the detected signal to the maximum and minimum desired light outputs. The light detector (146) and voltage sources (156, 157, 158, 159) are coupled to the window comparator (152, 154). A binary counter (162) selectively generates a periodic signal. An OR gate (160) couples the window comparator (152, 154) to the binary counter (162). A D/A converter (170) and light source driver (172) couple the binary counter (162) to the light source (140). The binary counter (162) provides the periodic signal as the input electrical signal to the light source (140) in response to the window comparator (152, 154) determining that the light detector (146) signal is not related to a light output between the maximum desired light output and the minimum desired light output.

Abstract: A machine for automatically filling plastic bags with liquid or particulate material moves a continuous web (13) of such bags through a number of serially positioned work stations. The bags (13) are completely sealed when they enter the machine. As each bag (13) passes through a slitting work station (71), a specially shaped opening is cut into the bag near an end of it which will become its top. When the bag proceeds to a filling work station, it is held vertically and a specially shaped fill nozzle (95) is moved downward and rotated for entry into the bag through the slit opening (145, 147, 149). A valve (117) is provided within the fill nozzle for controlling entry of the material into the bag. The valve and fill nozzle are cooperatively controlled by a single mechanism. The bags are transported through the various work stations by a positive toothed belt drive that preferably holds the bags flat until the filling station, wherein the belts are then moveable toward and away from each other in order to allow filling of the bag. After filling, the bag opening is then sealed. The various techniques are especially useful for aseptic packaging of foods, such as milk and wine. Fitments (67) for later use in removing material can also be added to the bag (13) in another work station (63). The bags and fitments are structured and carried in a way to cooperate with the machine.

Abstract: A hydraulic controller for an automatic transmission, having a band brake (B1) having a large stopping force based on a self-boosting effect against rotation in a self-binding direction and having a comparatively small stopping force against rotation in the unbinding direction, a modulator valve (30) for producing a modulator pressure by reducing a line pressure, a band brake hydraulic servo having a brake engaging hydraulic chamber (31) and a brake releasing hydraulic chamber (35). A line pressure is supplied to the band brake hydraulic servo to stop rotation in the self binding direction when a predetermined transmission speed is selected. The line pressure is also supplied the band brake hydraulic servo to stop rotation in the unbinding direction when another transmission speed is selected. A modulator pressure is supplied to the brake engaging hydraulic chamber to stop the rotation in the self-binding direction of the band brake and to allow the rotation in the unbinding direction when an intermediate speed is selected. The risk of any shift from the predetermined speed to another speed via the intermediate speed is eliminated, thereby enabling the transmission to be shifted always correctly while reducing shift shocks.

Abstract: The closed-­channeled, multi-passaged nozzles have gas-permeable refractory walls (20), allowing the escape of gases that may be dissolved in the molten metal and become expelled or liberated from it while the molten metal (25) is flowing through the passageways (27) in the nozzle. Gaseous voids in the continuously cast product are thereby avoided, notably in aluminum casting as shown by experimental results to date. The nozzles are made from gas-permeable refrac­tory material having interconnected porosity -- that is, inter­connected void interstices -- extending through the nozzle walls (32). The interconnected void interstices are of sufficient size for allowing the passage of hydrogen gas through the walls, while being sufficiently small for preventing the leakage of molten metal. The gas-permeable refractory material is relatively non-wettable by the molten metal. For example, the nozzles are made of fibrous sintered refractory material -- for instance, fibers of alumina or silica intertwined and cohered within a major volume-percentage of interstitial voids, which provide the interconnected porosity. Such fibrous material displays high resistance to thermal shock. It is relatively compliant to nozzle clamps, with consequent resistance to breakage, while the coefficients of thermal conductivity and thermal expansion of such fibrous refractory material are advantageously low.
