Abstract: In a GaAs semiconductor device, a portion of the drain region (22b) just under the drain electrode (25b) is shallower than the portion of the source region (22a) just under the source electrode (25a). With this improvement, the leak drain current creeping into the substrate is reduced while satisfactorily suppressing the short channel effect, which is inevitable in the prior art FET.

Abstract: A multi-cyclone (3) or the like type of separator is combined with a fast fall - slow rise circulation type crystallizer (2) in a manner which permits continous purification wherein a crystallizable substance is extracted by seeding the liquid and circulating the mixture in the crystallizer and any crystals which may overflow with the crystallizer effluent are removed by the cyclone arrangement. The system can be conditioned for batch processing wherein when the source fluid (1) is exhausted or limited in quantity, the content of the crystallizer can be drained and passed through the cyclone arrangement. Under these circumstances the crystal containing fraction which is released from the multi-cyclone separator is fed to a second separator (29) for separation into a clear liquid and a fraction which is concentrated in crystalline solid. The latter mentioned fraction is collected in vessels (25, 26) wherein a seeding suspension is prepared.

Abstract: Flame retardancy of polyphenylene ether resins is increased by blending with the resin a flame retarding amount of a halogenated polyester which is the reaction product of a halogenated phthalic acid or phthalic anhydride with an epoxide or hydroxy compound containing at least two hydroxyl groups. The polyphenylene ether resin may include homopolymers or copolymers of polyphenylene ethers or blends of polyphenylene ethers with vinyl aromatic resins such as styrene polymers and copolymers. The flame retarding polyesters are also effective as processing aids in improving the flowability and moldatility of the polyphenylene ether resins during melt processing.

Abstract: The invention relates to an inclined lift comprising several telescopic elements, the individual telescopic elements consisting of guide rails which are connected like a ladder and are guided on one another. The essential feature of the invention consists in the fact that, in addition to the guide rails guided on one another, a further guide rail is arranged in particular in the top area of the inclined lift, i.e. on the last telescopic guide rail. The further guide rail is arranged as a narrow track between the external guide rails of the last (top) telescopic element and is guided in a sliding manner on the latter. The load-lifting member (slide) is provided with additional roller equipment for guidance on the narrow track. The narrow track forms a so-called integrated ridge bend piece on which the slide is positively guided in the ridge area and on the opposite side of the roof. <IMAGE>

Abstract: A method and apparatus for selecting a particular node from a plurality of nodes connected to a common bus to allow the node to use the bus. The nodes have a pre­determined priority. After initially enabling the nodes, the bus is monitored for a bus idle condition. It is then determined which of the nodes are enabled message nodes, which are enabled nodes that have a message to send on the bus. There is then arbitration between the enabled message nodes after the bus is in the bus idle condition for a first period of time, such that the enabled message node having the highest pre-determined priority among the enabled message nodes is disabled for arbitration purposes, and also at the same time selects a target and performs a transfer. This procedure is repeated until all the enabled message nodes have been disabled. Thereafter, all of the nodes on the bus are enabled when the bus is in the bus idle condition for a second period of time, which is longer than the first period of time.

Abstract: A power steering system includes a bypass valve (40) for bypassing fluid from a main fluid conduit (34) connected between an engine-driven, power steering pump (26) and an actuatable, open-center, steering control valve (12) which is actuated upon turning of a vehicle steering wheel. When the steering control valve is actuated, the demand for fluid through the steering control valve to a power steering motor increases. The fluid pressure in the main conduit (34) varies as a function of the demand for fluid to the steering control valve. The bypass valve (40) is urged toward an open condition by a fluid pressure signal. The bypass valve is urged toward a closed condition by a spring and by a fluid pressure (74) which varies as a function of the demand for fluid to the steering control valve and as a function of vehicle operating parameter, such as vehicle speed. The fluid pressure which urges the bypass valve toward a closed condition is controlled by (i) a pressure responsive pilot valve (50) which is responsive to the fluid pressure in the main conduit and (ii) a solenoid operated valve (250) which is responsive to vehicle speed.

Abstract: The invention is based on the object of arranging a large number of splice modules (10) in a space saving fashion in such a way that each splice module (10) is freely accessible. 
<??>The object is achieved when the splice modules (10) are arranged on a carrier (21), each splice module (10) individually being swivellably connected to the carrier (21) in such a way that the swivel axis (14) passes through the interior of the splice module (10), to be precise parallel to the direction of the introduction of the optical waveguide bundle into the splice module (10), and the swivel axes (14) of several splice modules extending parallel to one another. Each splice module (10) is provided with hollow cylinders (25), which are mounted in U-sections (22). Optical waveguides are fed to each splice module through the hollow cylinders (25). Since the hollow cylinders (25) remain fixed upon swivelling of a splice module (10), there is no need for excess length in the optical waveguides (11), in order to be able to swivel the splice module (10). By swivelling the splice modules (10), the latter can be "leafed through" like a book. Each individual splice module can be rendered accessible in this way, so that the optical waveguide splices located on it can be renewed or repaired.

Abstract: A voltage reference circuit is described which is capable of providing either an internally generated voltage having a trimming capability, or an externally generated voltage, with the use of only two pins (2,4). The internal voltage is connect­ed through an interrupt circuit (T2,T3,R4,R5,R7) to an input/­output terminal (2), which can also receive an externally gene­rated voltage. A trimming terminal (4) is used to apply trimming voltage signals to adjust the internally generated voltage. To convert from the internal (8,A1) to the external voltage source (20), an interrupt voltage is applied to the trimming terminal (4) which is outside of the normal trimming voltage range. This interrupt voltage actuates an interrupt circuit (T2,T3,R4,R5,R7) to interrupt the connection (T1) between the internal voltage source (8,A1) and input/output terminal (2), leaving the output terminal (2) available for the external voltage source (20).

Abstract: A single international standard integrated services digital network (ISDN), basic rate interface (BRI) is arranged so that either a data terminal and two voice terminals, three voice terminals, or four voice terminals can be operated simultaneously through the interface. Code converters (65,66), associated with the voice terminals (24-29) and with a central office switch (30), convert eight-bit voice sample code from either the voice terminals or the central office switch to four-bit voice sample code in the interface to enable the bit streams of two voice terminals to be merged for transmission through a single B-channel at the interface. When two voice terminals are operated simultaneously through one B-channel, each of those terminals positions four-bit coded voice samples in a different sub B-channel of the B-channel and stuffs four bits in the other sub B-channel. Four-bit coded voice samples from the sub B-channels are converted to voice samples in the voice terminals and to eight-bit codes voice samples in the central office switch.
