Abstract: A catheter adapted to perform electrophysiological procedures comprises a body member (11), a manipulation handle (20) attached to the proximal end of the body member for applying torque to the body member, the handle having a control knob (43) adapted for control movements in a first plane (62) and in a second plane (66) simultaneously. A deflection control line is attached at its distal end to the distal portion of the catheter and its proximal end attached to the control device of the handle so that tension applied to the control line by sliding the control knob causes deflection of the distal portion of the catheter. A stiffening member (31) is disposed within the body member of the catheter and is slidable, said stiffening member providing increased rigidity to the portion of the body member in which the stiffening member is located. Rotation of the control knob controls the position of the stiffening member in the body member. In a further aspect, a stiffening member in accordance with one embodiment includes a tapered distal end section with a ball formed on the distal tip, the tapered section terminating at the ball. In accordance with another aspect, the torsional rigidity of the catheter body is increased by use of a layer of aramid fibers mixed with an epoxy. In yet another feature, the handle and rotatable sliding element are symmetrically shaped to facilitate complete single-handed operation of the handle by the physician of all position control aspects of the catheter.

Abstract: For the injection-moulding from thermoplastic material of articles 10 which enclose a hollow space 15 by their walls 13, 14, a process is proposed in which a mould cavity 23, pre-limited in its volume, of a mould 20 is initially fully injected with the polymer melt 31 and then enlarged in its volume and is subjected to a fluidic pressure medium in order that the polymer melt 31 is distributed along and applied to the walls of the enlarged mould cavity volume, thereby forming the hollow space. In order that the desired or required hollow spaces 15 can be moulded in the articles 10 exactly reproducibly, the fluidic pressure medium is injected into the polymer melt 31 completely filling the pre-limited mould cavity volume - if appropriate after the elapse of an interval or rest period following after the polymer melt injection operation - and the volume of the mould cavity 23 is not deliberately enlarged until during or with the injection of the said pressure medium and/or in a manner dependent on this injection of the fluidic pressure medium into the polymer melt 31. <IMAGE>

Abstract: The invention relates to the structure of a field emitter device, to the method of fabricating a field emitter device and to the use of the field emitter device in the technical field of flat panel displays. 
     The field emission device comprises an array (1) of widely-spaced tips (2) for emitting electrons and a perforated extracting electrode (3) facing the array of tips. An individual series resistor is formed by each of said tips itself. The widely-spaced tips are not surrounded by a layer of electrically insulating material. 
     The tips are not surrounded by an insulating layer and the tip end is not surrounded by a gate or extraction electrode. This avoids failures like shorts between the cathode electrode and the gate or extraction electrode which could occur due to inaccurate coating or etching processes and enhances the reliability and the life-time of the array of tips. 
     To fabricate the field emission device a micromechanically manufactured array (1) of widely-spaced tips (2) and a micromechanically manufactured perforated extracting electrode (3) are provided. The outer sides of the perforated extracting electrode are bonded to the array in a way that the perforated extracting electrode is facing the array. 
     With the array of widely-spaced tips and the perforated extracting electrode being fabricated separately and bonded together subsequently, both the number of process steps required for each of the two parts and the manufacturing process costs are reduced.

Abstract: Split sprocket wheels having interlocking tabs for forming a sprocket wheel assembly that is easy to install on and remove from a drive or idler shaft of a belt or chain conveyor. The invention provides thin, durable sprocket wheels (20) split into at least two sectorial sections along seams (32) extending from a central bore to an outer engagement surface (30). Mating tabs (24,26) and receptacles at the edges of adjacent sectorial sections interlock the adjacent sections radially and circumferentially. Holes (23) in the vicinity of the mating tabs and receptacles of adjacent interlocked sections admit locking means for holding the sectorial sections together in axial compression. The sprocket wheels can be ganged together at selected positions along a shaft with their bores in coaxial alignment by means of spacers interconnecting consecutive sprocket wheels along the shaft. Sprocket wheels can be disengaged for removal from the shaft by loosening the locking means and sliding one section axially with respect to the other section by a distance as little as the thickness of the thin sprocket wheel. Then each section can be removed from the shaft without the need for dismounting the shaft from the conveyor system.
