Abstract: On the outer periphery of a holder (121) having an elastic flange part (121a), a head arm member (107) for supporting a magnetic head (106) and a thin-plate circuit connecting plate (122) are fitted. Concurrently, the head arm members (107) are fastened to the holder (121) by the pressure exerted by the holder (121) in a radial direction, and the circuit connecting plate (122) is fastened to the holder (121) by the elastic force exerted by the flange part (121a) between the head arm member (107) and the flange part (121a). Thereby, while high alignment accuracy is maintained, the circuit connecting plate can be manufactured at a low cost without the requirement of any strict machining accuracy.

Abstract: A multicast switch fabric is described wherein blocking of desired signal paths is handled by storing a cell to be transmitted through the fabric at a buffer at an input port to the fabric and attempting to retransmit the cell through the fabric until the cell is successfully transmitted, or a maximum number of retries at transmission is reached. Each switch element in the fabric has a block register which stores information as to whether or not a request path including that element is blocked, the block signals being fed back to the input port to indicate whether or not cell transmission has been successful. A 2 x 2 switch element is described wherein header information from the cell is decoded in two subfields, one field determining the number of copies to be replicated in the switch and a second field determining if the cell is to be fully replicated at each subsequent stage of the fabric.

Abstract: Method and apparatus useful for eight-level halftone thermal ink jet printing by printing with droplets of ink with volumes weighted in a binary sequence. Three binary-weighted drop generators (50, 52, 54) which are fired in sequence are useful in an eight-level, three color printing process and additionally may be employed with a clear ink vehicle drop generator (60) in order to reduce optical density of single small dots in a given pixel area to thereby reduce grainyness. This method and apparatus are also adapted for three color number printing with a chosen number of rows and columns of binary-weighted drop generators, (84, 86, 88) including untoned vehicle if desired, in order to achieve color printing of pixels having desired color and optical density.

Abstract: A device for measuring the displacement of a movable object includes a stationary light source (10) that produces an incident light beam. A target feature (17), attached to, or integral with, the object, reflects the incident light beam and forms a first image of the light source in close proximity of the target feature. An imaging lens (26) receives the reflected light beam and reforms the first image of the light source as a second image on the photodetector (20). The photodetector, spaced from the object, receives the reflected light beam and produces an electric signal having a characteristic which is proportional to a received location on the photodetector of the second image and which represents a position of the object. The target feature includes a curved surface that reflects the light beam such that a small, point-like or line-like first image of the light source is formed and reformed as a second image on the photodetector.

Abstract: In a coded orthogonal frequency division multiplex (COFDM) system n-bit data words are encoded as 2 -symbol code words (binary, quaternary, octary, etc.). The code words are selected for desired low peak-to-mean envelope power ratio (PMEPR) characteristics of transmissions over a COFDM channel, from a set of cosets of a linear subcode of a code having a specified generator matrix. The code words thus identified by the procedure described can, even for values of m in excess of 3, simultaneously limit the PMEPR to 3 dB, provide specified error control characteristics, be implemented in a feasible manner using analytical circuit techniques (e.g. with combinatorial logic), and include sufficiently many different code words to enable data to be transferred at useful rates. Other selections of code words can be made, enabling a higher maximum PMEPR or a reduced error detection capability to be accepted in order to obtain a higher code rate.

Abstract: A complex computing system has a plurality of nodes interconnected by channels through which data messages are exchanged. The underlying principle is that after arrival at a node of a message, delivery of that message is delayed until after delivery and consequences of all more senior messages which affect the node. The messages are progressively timestamped at each node so that each time stamp contains generation by generation indicators of the origin of the associated message. The seniority of that message is uniquely determined thereby and total ordering of the messages can be achieved. When comparing timestamps for such ordering, comparison of respective generation indicators is necessary only until there is a distinction.

Abstract: A method and apparatus for increasing the operational bandwidth of a multimode optical fibre communications system is provided. The method comprises launching optical radiation into the core of the multimode fibre away from the centre of the core so as to strongly excite mid order modes of the multimode fibre, but to only weakly excite low order and high order modes of the multimode fibre. The mid order modes excited are predominately within a small number of mode groups and thus have similar propagation constants. This leads to a reduction in modal dispersion and thus to a significant increase in bandwidth compared to an overfilled launch. The offset launch of the invention is tolerant both to the launch conditions and to any imperfections in the fibre refractive index profile. Modal noise performance is also enhanced. Embodiments of the invention employ a singlemode fibre, a multimode fibre or a lens to illuminate an end face of a multimode fibre with a small spot offset from the optical axis of the fibre.

Abstract: A discriminant function is defined by conventional learning discriminant analysis (22) and a value of the discriminant function is calculated (23) for all the training patterns in the in-category pattern set of each category and for all the training patterns in the rival pattern set of the category. The in-category pattern set is composed of all the training patterns defined as belonging to the category. The rival pattern set is composed of the training patterns that belong to other categories and that are incorrectly recognized as belonging to the category. An in-category pattern subset and a rival pattern subset are then formed (24) for each category. The in-category pattern subset for the category is formed by selecting a predetermined number of the training patterns that belong to the in-category pattern set and that, among the training patterns that belong to the in-category pattern set, have the largest values of the discriminant function. The rival pattern subset for the category is formed by selecting a predetermined number of the training patterns that belong to the rival pattern set of the category and that, among the training patterns that belong to the rival pattern set, have the smallest values of the discriminant function. A linear discriminant analysis operation is then performed (25) on the in-category pattern subset and the rival pattern subset to obtain parameters defining a new discriminant function. The reference vector and weighting vector stored in the recognition dictionary for the category are then modified using the parameters defining the new discriminant function.

Abstract: The invention relates to an apparatus for forming liquid droplets, such as a micro nebulizer, useful for preparing samples for subsequent analysis via MS, AA, ICP, CE/MS, and similar analytical systems. The apparatus has a mechanically stabilized inner microtube (12), thereby ensuring controllably uniform droplet size. The mechanical stabilization is provided by securing the inner microtube (12), such as by narrowing the inner diameter of the outer microtube (14) or otherwise narrowing the annular intermediate space between the inner and outer microtubes (12, 14) for a predetermined length. Thus the inner microtube (12) is secured in a centered or otherwise predetermined fixed radial position, with minimum perturbation of the flow. Further, a tip (22) when coupled with the exit end of outer microtube (14), provides a region in which the sheath fluid flow in the outer microtube (14) stabilizes prior to both exiting the tip (22) and colliding with the liquid analyte exiting the inner microtube (12).
