Abstract: The invention relates to an ISDN subscriber circuit with a network termination unit (1), which is coupled on the one hand with an exchange (2) and on the other hand with a connection of a main station or an extension, to which different terminal units (6 to 13) can be connected. An interface (3) is disposed between the network termination unit (1) and the terminal units (6 to 13). The interface can be coupled with a first group of terminal units (6 to 9) via a first internal link (4) to two user data channels and with at least a second group of terminal units (10 to 13) via a second internal link to two user data channels. The interface performs switching functions between the terminal units and between terminal units and/or an external subscriber. When a connection is requested by an internal or external subscriber, the interface transmits a connection request signal to all terminal units. <IMAGE>

Abstract: A method of heating molten material in a tundish employs a plasma torch. The plasma comprises a mixture of argon and one or more of nitrogen, hydrogen, neon and helium. A mixture of argon and helium including from 10 to 20% by volume of helium is useful for heating steel. For an arc of given length, a higher voltage is obtainable than when pure argon is used as the plasma gas. The torch is preferably engaged by a horizontal support arm which is pivotally mounted on an extensible support so as to facilitate location of the torch in a limited space above the tundish.

Abstract: A method for electrically connecting planar element substrates (12) to form an array (10) by forming conductive bridges (16) between metal pads (14) located on the surface of array elements (12). The conductive bridges (16) are formed to be nearly coplanar with the planar elements (12) and are made to connect the end faces (14b) of pads (14) which are fused to the planar substrate (12). Metal wire (16a), solder (16b-c), a conductive polymer (16d), or a suspension of conductive particles in paste (16e) are used to form the bridges. The bridges (16) have a low profile, occupy a very small area and reduce the need for highly accurate alignment of adjacent substrates (12) within the tiled array (10) before electrical connections are formed. These low profile bridges (16) are especially advantageous tn that they allow a protective plastics or similar cover sheet, or a liquid crystal laminate, to be surface mounted on the adjacent array (10) without causing detrimental surface blemishes or ridges. The small area of the bridges (16) greatly reduces the non-transmitting area of the visual display. The bridges (16), being substantially narrower than the pads (14) which they connect, are more likely to connect the intended pads (14) and less likely to "short" pads (14) which are not in accurate alignment.

Projector auxiliary parts (31, 32, 34) are arranged on the support rods (18) such that they can be displaced axially and can be adjusted in a lockable fashion. A light projector (10) suitable in particular for heavy projector auxiliary parts (31, 32, 34) is provided when the main housing part (16) forms a joining bridge which is rigidly and non-displaceably mounted on the two housing mounting points (17) between the two support rods (18). In this case, in addition to the tilt adjustment in the tilt axis (z) the two support rods (18) are also retained inside on the bracket limbs (12, 13) such that they can be displaced axially and can be adjusted in a lockable fashion. <IMAGE>

Abstract: An image forming apparatus comprises an image forming unit for forming and transferring an image of a document to a copy sheet, a fixing unit (19) including a fixing roller (191) for fixing the document image to the sheet while transporting the sheet, a heater (193) for the fixing roller, and a heater control unit (34) for turning the heater on and off at specified timings so as to establish and maintain the temperature of the fixing roller in a predetermined range whose upper limit is a fixing temperature. The copy sheet heated by the fixing roller has a temperature of about the predetermined fixing temperature while in transport, whereby the image transferred to the copy sheet is fixed thereto. A control unit (30) acts on the heater control unit (34) so that it controls the heater over the period during which a copying operation is completed. The heater control unit on-off controls the heater only during the copying operation. Accordingly, power consumed by the heater is reduced and an unwanted temperature increase within the apparatus can be avoided.

Abstract: A subband filtering method for a stereo audio signal comprises the steps of selecting the filter coefficients necessary in a stereo L- and R-channel filtering so as to be jointly shared and simultaneously filtering stereo L- and R-channel signals using the jointly shared filter coefficients. A filtering apparatus reads out the filter coefficients selected from the memory area by a memory controller and filters the audio signal of the stereo channel by parallel-processing. Thus, coefficient memory space is saved so as to achieve high hardware integration. More particularly, the simplification of a digital-signal-processing integration circuit can be achieved whenever time-division-multiplexing (TDM) processing is not practical or, in the event of TDM-processing, when power consumption becomes excessive.

Abstract: Ammeline-melamine-formaldehyde resins (AMFR) containing from 5-100% ammeline were synthesized by the polymerization of the sodium salt of ammeline, which must be made in advance, melamine, and formaldehyde in basic medium (pH = 9.2-10.0). In this copolymerization, it is possible to make uniform random AMFR resins with any mole ratio of ammeline salt to melamine. Preferably the AMFR resin will contain from 5-10% ammeline. As an "ionomer" or a "poly-electrolyte," both the solid and solution properties of these resins (such as melting temperature, solubility, solution stability, etc.) depended directly on the mole ratio of ammeline to melamine and formaldehyde, and/or on the pH value of the medium in which the AMFR resin was present. The pH value controlled the ammeline rings/ammeline's salt groups and also the ratio of unprotonated to protonated amino groups on both the melamine and ammeline rings. These polymers have different solubilities, cloud points and solution lifetimes (which depend on pH) than melamine-formaldehyde resins. AMFR systems containing from 5-10% ammeline are more flexible than MFR resins and exhibit different adhesion properties than MFR resins.

Abstract: An integrated circuit includes a clock alignment circuit (10) having a frequency synthesizer (12) for receiving a reference clock signal (CLKIN) at a lower frequency and for generating phases (CLK1, CLK2, CLK3, CLK4) of an oscillator clock signal at a higher frequency. The oscillator clock signal phases (CLK1, CLK2, CLK3, CLK4) drive a desired clock signal phase generating circuit 26 that generates various phases of the desired clock signal. The desired clock signal phases (CLK1, CLK2, CLK3, CLK4) are systematically compared to the reference clock signal (CLKIN). The phase of the desired clock signal that is determined to align with the reference clock signal (CLKIN) is provided as the desired clock signal output from the integrated circuit such that there is no apparent time delay through the integrated circuit. In an alternate embodiment, a single phase of the desired clock signal is selected and a phase locked loop adjusts the oscillator (20) in the frequency synthesizer (12) to align the selected phase of the desired clock signal with the reference clock signal (CLKIN).
