Abstract: The electro-migration of electrode metal takes place under an elevated temperature condition in amorphous silicon devices having conventional PI-type, NI-type, or PIN-type hydrogenated amorphous silicon layered structures, which substantially degrades the electrical characteristics of the device. This problem is solved by forming a chemically inactive layer consisting mainly of amorphous silicon oxide on the surface of amorphous silicon layer by washing and drying process, to establish electrical contacts through the chemically inactive layer between the hydrogenated amorphous silicon layer and either a collector electrode or a transparent electrode. This structure not only prevents such electromigration of electrode metal, but it also allows a greater freedom for choosing a material for the collector electrode.

Abstract: A method for making a composite poppet valve, and a poppet valve fabricated using that method. A composite slug (22) is formed of a cylindrical core (15) of a light weight metal such as titanium to which is fixed as by friction welding a disc or cup shaped element of a wear resistant cladding material such as steel (16). The composite slug is first extruded, wear resistant material first, through an extrusion die to form a blank followed by a restriking process to form the head portion of the valve into its final shape. The configurations and proportions of the core and cladding material are controlled to produce a poppet valve having a light weight core and a wear resistant cladding which varies in extent from defining the tip (18) of the valve with cladding extending part way up the stem to a configuration wherein the cladding material completely encapsulates the core material.

Abstract: Congestion control is implemented at the resources that actually suffer from congestion and, moreover the congestion control is performed within the network as well as at its access points. In a particular embodiment, congestion control is continuously performed at each resource. Use of each resource is controlled according to a head-of-the-line weighted round-robin service discipline thereby assuring fairness and full use of bandwidth for all active channels. Also, in order to control conditions of congestion, the queue of data elements waiting for service at each resource is regulated by a global congestion indicator for the entire queue. The data elements of each channel that are waiting for service are further regulated in response to specific local congestion indicators that are individualized for each channel. The global and local congestion indicators are used to guarantee predetermined levels of service for each channel. The values employed for the head-of-the-line weighted round-robin service discipline are developed as a function of at least the contracted-for bandwidth for each channel. The developed values are replicated for each resource subject to congestion control.

Abstract: The present invention relates to a system for variable-length-coding and variable-length-decoding digital data (e.g. video and/or audio data) divided into block units of a predetermined size. The system, in operation, comprises the steps for variable-length-coding each block data according to various scanning patterns, accumulating the various lengths of variable-length-coded data, selecting a scanning pattern corresponding to a minimum accumulated length, transmitting the variable-length-coded data according to the selected scanning pattern and scanning the transmitted data according to the same scanning pattern as applied to the variable-length-coding process, whereby the scanned data is variable-length-decoded. As a result, data compression can be improved efficiently by means of utilizing an optimized scanning pattern for variable-length-coding and variable-length-decoding of the block data.

Abstract: A transmitter and a receiver element (2, 3) are arranged closely adjacent in such a manner that they have access to the same optical waveguide interface (4). This permits, in particular, the construction of a greatly simplified optical serial multimaster bus system with an optical star coupler and single-guide optical waveguide connections, on which standard autobus protocols can be implemented. On a substrate carrier (5), in particular a stamped metal systems carrier, there are closely arranged next to one another a luminescent diode (LED) (2) as transmitter element and a photodiode (3) as receiver element. The two diodes (2) and (3) are closely adjacent such that they have access to the same optical waveguide interface (4). All suitable electrooptical transducers can, in principle, be used as transmitter and receiver elements, a luminescent diode being, however, considerably more advantageous for the transmitter element than a laser diode, as otherwise the laser light incident on the other transmitter diodes can produce interference. In Figure 1, there are illustrated as further components arranged on the substrate carrier (5) an integrated circuit (6) and a discrete component, for example a capacitor (7), which are electrically connected to the transmitter and receiver elements (2) and (3) and form in conjunction therewith an evaluation circuit. The entire arrangement is provided with a housing (8) and forms a T/R module (1) into which the optical waveguide interface (4) is also integrated. <IMAGE>
