Abstract: A known method of producing a defined thickness in an optical waveguide taper is to pass a diaphragm over the substrate with a certain nonuniform velocity. Only large-area tapers and only one taper per substrate can be produced by this process. The object is to provide a method with which a plurality of optical waveguide tapers can be produced on one substrate. For this purpose, a substrate is etched, eroded or coated in an irradiation processing step and the radiation density or exposure time per unit area is altered between two ends of each structure to be produced. This can be done, for example, with a diaphragm (2) which is passed at a constant velocity over the substrate (6) and with a stationary mask (4) which is mounted above the substrate and has openings (5) at points where optical waveguide tapers are to be produced. The diaphragm (2) is moved over or under the mask (4) in such a way that opposite ends of the substrate (6) visible through the openings (5) are subjected to a processing step for different lengths of time. The processing step may, for example, be a dry-etching step, but it may also be a step designed to apply or vapour-deposit a layer on the substrate (6). This produces etched wedge-shaped recesses (7), or vapour-deposited wedge-shaped structures (8) which also become etched wedge-shaped recesses (7) as a result of a subsequent etching step using a mask (4). <IMAGE>

Abstract: High frequency printing mechanism with an ink-jet ejection device which is capable of ejection of ink (including hot melt ink) at jet frequencies greater than 50,000 Hz. A cantilevered beam (12) is mounted at its base (14) to a piezoelectric element (18) which oscillates the base. The beam is shaped so that its moment of inertia is reduced toward its free end (16). The element (18) is activated by an oscillating electrical signal the frequency of which is equal to or close to a natural frequency of oscillation of the beam (12). At this frequency of oscillation of the beam, the tip (15) of the beam ocillates over an amplitude which is significantly greater than the oscillation amplitude of the base. The tip (15) of the beam is provided with an aperture which is preferably tapered in cross-section. One opening of the tapered aperture is in fluid communication with a reservoir (19) of ink and the other opening of the aperture is positioned at an appropriate distance from a printing paper towards which individual droplets of ink from the reservoir are to be propelled. When the tip amplitude is above a predetermined threshold, the solid-fluid interaction between the aperture and the ink causes a drop of ink to be accelerated through the aperture and be ejected upon each excursion of the tip of the beam toward the printing media.

Abstract: In order to detect impurities, especially foreign fibres, in threads light which is reflected on the thread is picked up using a sensor (S1) and produces a first measurement signal (FFMW) whose magnitude is dependent on the occurrence of an impurity and on the diameter of the thread. In order to eliminate the diameter-dependent component of the signal, a second measurement signal (MW) is picked up which is essentially dependent only on the diameter of the thread. By linking the two signals in a computer (3), the influence of the thread diameter on the first measurement signal is essentially compensated for. <IMAGE>

Abstract: A dot matrix impact print head device having a plurality of print units. In each of the print units, an end of a support leaf spring (24) supported on a print head body and an end of a drive leaf spring(25) whose another end is connected to a piezoelectric element (5) are joined parallel to each other by a rigid joint (26). The joint is fixed to a proximal end of an arm (22).When the support and drive leaf springs are resiliently deformed, the arm is angularly moved about a pivotal center axis (31) defined by these leaf springs. A line (32) interconnecting the axis (31) and the proximal end of the print wire (7a) extends substantially perpendicularly across the direction of back-and-forth movement of the print wire. When a piezo-electric element (5) is displaced in response to the application of a voltage, an arm (32) is angularly moved through the two leaf springs (25, 26) to move a print wire (7) mounted on the distal end of the arm (22) back and forth.

Abstract: A method for routing a packet of information between two hosts that are coupled to a network. Each of the hosts have a unique network address, and at least one of the hosts is a mobile host (10) that does not have a fixed network coupling location. The method includes a first step of (a) transmitting a packet from the mobile host to a second, destination host on the network through a wireless link that is established between the mobile host and a base access station (12) that serves a current physical location of the mobile host. The base access station is coupled to the network via a subnetwork (LAN) (14), and the packet includes a first Internet Protocol (IP) Loose Source Routing (LSR) option that includes a network address of the base access station. A second step (b) receives with the destination host the packet that includes the first IP LSR option. A third step (c) transmits a further, reply packet from the second host to the mobile host via the base access station in accordance with a path reversal technique wherein the reply packet includes a second IP LSR option that specifies as a first Routing address the network address of the base access station. As a result, the reply packet is directed through the network to the base access station that serves the current physical location of the mobile host, and an optimal, fast routing of the packet is achieved without involving intermediate gateways (16, 18).
