Abstract: An optical waveguide coupler comprises two optical waveguides in the form of optical fibres (1,2) closely spaced apart to allow light propagating in one optical waveguide to couple into the other. The fibres 1 and 2 have cores (3,4) made of materials having different refractive indices, respectively. This stabilizes the splitting ratio against a large change due to a slight change in coupling length, whereby the control of the coupling ratio during manufacture becomes easy, and deviations in splitting ratio can be greatly reduced.

Abstract: Forming hollow, box-section, frame members which include localized reinforcement. The frame members are produced by fitting a sleeve (11) about a tube (10), deforming the tube (10) and sleeve (11) to avoid the occurrence of pinching on closing of die sections about the deformed tube and sleeve in a sectional die, and then expanding the tube and sleeve in the die to form the hollow, box-section, frame member in which the sleeve (11) is mechanically locked on an inwardly offset intermediate portion (14) of the tube (10). The expansion is achieved by application of an internal pressure within the tube.

Abstract: The invention incorporates an intermediate foil layer for joining machine parts at risk of fretting corrosion. This intermediate foil layer comprises at least two foils situated one on top of another and whose mutual contact surfaces have a lower friction coefficient and are more resistant to wear than their outer surfaces. It is achieved as a result that in the event of vibrational loading relative movement between the machine parts to be joined is transmitted onto the contact surfaces of the foils, which slide well and are resistant to wear, and this increases the service life of the machine parts and prevents damage due to fretting corrosion.

Abstract: A gas-lubricated mechanical seal, the slide ring (20) of which rests with its slide surface (22) on the slide surface (21) of a counter-ring (19), said slide ring being held, on a wall (4) to be sealed off, fixedly in terms of rotation and displaceably in the axial direction against springs (35). The counter-ring (19) is attached non-movably and in a sealing manner to an intermediate sleeve (10) which, in turn, is mounted rotatably, on the shaft (2) to be sealed off, by means of roller bearings (16) and is sealed off against the shaft by means of a dynamic sealing device (15). Arranged furthermore between the shaft (2) and the intermediate sleeve (10) is a free-wheel (17) which couples the shaft to the intermediate sleeve (10) when it rotates in its normal direction of rotation (1'), by which means the counter-ring (19) is driven and conveying grooves (24) arranged in its slide surface (21) pump gas out of the chamber (6) to be sealed off between the two slide surfaces (21, 22), which gas forms pressure cushions effecting their separation. In the opposite direction of rotation (2"), the free-wheel (17) is decoupled, by which means the slide surfaces (21, 22) are prevented from executing a relative movement taking place in reverse to that executed in the case of the normal direction of rotation (1'), in which relative movement gas would be extracted from between the slide surfaces and the slide surfaces would quickly be destroyed by the greatly increased friction. …<IMAGE>…

Abstract: A liquid crystal display unit is provided wherein address lines (13) for two mutually adjacent odd and even rows of pixels (11) arrayed in a matrix are in common, and two vertical pixels on each column can be displayed simultaneously to enable display of an image corresponding to one frame. Capacitor forming electrode wires (14) are supplied with a fixed potential are disposed between omitted rows of address lines eliminated due to the common use thereof, whereby the storage capacitors (Cs) are of a sufficiently high value, even with a high resolution display, to enhance the image quality of the liquid crystal display unit. Since a fixed potential is applied to the capacitor forming electrode wire which forms the storage capacitor, the capacitor does not apply a load to the address line and thereby consistently insures a fast operation. As a result, improvements can be achieved relating to large image area and high resolution. Furthermore, each pixel includes a switching transistor (Tr) which is composed of a thin film transistor having a high carrier mobility and is formed under a single line so that even when the on-resistance of the transistor is lowered, the aperture ratio of the pixel is still enhanced to obtain a high resolution.

Abstract: A digital-to-analog converter (DAC) ladder segment is disclosed in which diode networks are introduced into the ladder step circuits. Each diode network includes a control diode which controls the flow of current through the network in accordance with a signal from an associated actuating circuit, which in turn is controlled by an input digital signal. In one embodiment, the control diodes are connected in series with resistors, with the diodes and resistors scaled so that their respective bit circuits conduct desired current levels. In another embodiment, the control diodes have equal scalings and are connected in series with respective resistors and second diodes which are scaled so that their step circuits conduct the desired currents. In a third embodiment, current sources are provided which supply currents to the second diodes in amounts that permit the second diode and the resis­tors for the various step circuits to have substantially equal scalings. The different embodiments can also be combined to obtain the advantages of each. Current errors associated with metallization resistances are substantially reduced by imple­menting the control diodes as bipolar transistors, having their bases and collectors connected together at a location remote from the diodes by means of metallic base and collector leads that are electrically isolated from each other in the vicinity of the diodes.

Abstract: In computer image generation (CIG) systems, image data for defining pixel modulation values and for supporting a display having a predetermined resolution are determined for defining a scene. For some applications, such as for representing background and/or peripheral areas, it may be acceptable to use data having a lower resolution than the predetermined resolution. Method and apparatus for taking a portion of the image data obtain derived data by a predetermined combination of the portion of image data. Lines of composed data supplied to a display device include a sequence of pixel modulation values selected from the portion of image data and the derived data. In one embodiment the number of lines supported by the image data is doubled with each line containing 50% image data and 50% derived data. Pixel modulation values may be oversampled between adjacent lines of the display for obtaining derived data. Respective composed data for a plurality of display devices may be obtained from a respective plurality of portions of the image data, thus obviating the need to provide additional video processing channels along with associated hardware.

Abstract: An ostomy coupling has two co-operating coupling elements (20, 40). One (40) is for attachment to a medical grade adhesive and the other (20) is for attachment to an ostomy pouch. Each element (20, 40) is of close loop form and includes a tapering member (28, 48) extending around a stomal orifice (18). Each such member (28, 48) tapers in a radially outward direction and has a flat surface (27, 47) located in a plane at right angles to the coupling axis. The coupling also has a means of clamping (60) which can be tightened onto the tapering members (28, 48) to hold them together. When held their respective flat surfaces (27, 47) are in face-to-­face arrangement. Hence, two coupling elements (20, 40) can be held together and released without the application of any axial pressure forces or pulling forces to the wearer of the ostomy appliance.

Abstract: Where short TR MRI imaging sequences are required (e.g., for contrast media imaging), NMR signal strength losses are reduced by including an extra preparatory nutation pulse at an interval TR prior to the usual nutation sequence used to elicit an NMR RF response. The "dead time" during such a TR interval for one slice is utilized for eliciting and receiving NMR RF responses from at least one other slice and sending the extra preparatory nutation pulse into yet another slice thus effecting a multi-slice procedure with an effective TR less than the actual time between repetitions of a complete multi-slice projection sequence while yet retaining high signal strength.
