Abstract: A polarimetric directional field sensor comprises an emitter and receiver (1) of measurement signals, connected by optical fibres (2, 2a, 2b) to a portable probe (3). The probe (3) comprises an optical element (11, 13) sensitive to the field to be measured and means (9, 20) for polarizing the measurement signal. The optically sensitive element (11,13) is in the form of a birefringent crystal having a crystalline structure which provides at least one plane in which the induced birefringence is modified by a single component of the field to be measured. The crystal is cut and oriented in the probe so that the direction of propagation of the optical measurement signal inside the crystal is normal to this plane, the polarizing means (9, 20) being oriented at 45° to the orthogonal axes in which the crystal's refractive indices are modified by the desired component of the field.

Abstract: The magnetic material of the Sm-Fe-N system contains a crystalline, magnetically hard phase having the Th2Zn17 crystal structure with N atoms incorporated in its crystal lattice. According to the invention, this magnetic material is to be prepared by first preparing a precursor containing the two-component Sm2Fe17 phase by mechanical alloying and heat treatment. The precursor is to have a predetermined microstructure. The precursor is then heated in a nitrogen-containing atmosphere, and in this process the magnetically hard phase is formed. The precursor with the predetermined microstructure can also be obtained by means of a quenching technique. <IMAGE>

Abstract: A method and apparatus for cleaning filter elements (68) that are vertically positioned within a filter vessel (52) that has a tube sheet (66) dividing the filter vessel (52) into a lower filter compartment (62) and an upper plenum compartment (64). A fixed volume of backwash liquid is rapidly directed from the plenum compartment (64) above the tube sheet (66) through the filter elements (68) into the filter compartment (62) that has been drained of liquid. The rapid movement of the backwash liquid is a result of a pressure differential between the plenum compartment (64) and the filter compartment (62). The volume of backwash liquid is maintained above the tube sheet (66) by a pressurized condition in the filter compartment (62), which volume may be changed by adjusting the pressure in the filter compartment (62).

Abstract: A production system (10) for garments or other products includes a plurality of work stations (12) for performing a series of work operations in which parts of a garment or other product are progressively manufactured. A conveyorized transport system (14 to 24) extends between the various stations (12) and the flow of work between the various stations (12) is regulated by assigning class codes to each operation required for a garment and each operation available at the various work stations (12). The class codes for a given garment order are read sequentially from a data memory and as a requirement for each code or work operation arises in the course of producing the garment, the scheduler searches a second data memory to locate the work stations which offer the work operations corresponding to the class code sought. The scheduler then determines from among the available work stations (12) the specific work station to which the garment pieces are sent for performing the required work operation.

Abstract: A technique for use in a direct digital color proofing (DDCP) system (500) for printing a "modelling" color(s) in a halftone color proof image such that the modelling color simulates a ("special") color that does not lie within a gamut of colors reproducible through only primary color (e.g. cyan, magenta, yellow and black) halftone printing. Specifically, a wide range of such modelling colors can be produced by independently and appropriately setting dot size, particularly in combination with solid area density, for the halftone dots (110, 120, 130, 140) produced for different primary colors and then printing the resulting dots on an overlaid dot-on-dot basis with proper registration. Appropriate dot gain and density look-up tables (230, 720; 240, 940) are respectively used to transform continuous tone separation values and bit-mapped data to vary dot size and solid area density of these halftone dots for each such primary color prior to printing these dots using a proofing engine. A unique set of tables is used to produce each different modelling color.

Abstract: Disclosed is a process of preparing a catalyst supporting highly metal particles comprising, in the presence of carbon monoxide in a solution containing a metal-containing ion and a support on which metal particles produced by reduction of the metal-containing ion are supported, reducing by means of a reductant the metal-containing ion to the corresponding metal particles which are then supported on the support. According to the process of the present invention, because of the presence of the carbon monoxide which is supposed to have a function of depressing the deposition of a new metal particle present around the metal particles supported on the support, that is, the growth of the metal particles and another function of preventing the agglomeration among the metal particles supported, the catalyst of excellent properties having the metal particles supported and monodispersed on the support with the narrow particle size distiibution can be prepared of which an average particle size is not more than 20 Å. After the preparation of the catalyst, the carbon monoxide can be easily taken out from the system so that no harmful effects are produced by the employment of the carbon monoxide.

Abstract: A RISC processor is arranged to reduce a code size, make the hardware less complicated, execute a plurality of operations for one machine cycle, and enhance the performance. The processor is capable of executing N instruction each having a short word length for indicating a single operation or an instruction having a long word length for indicating M (N<M) operations. When the number of operations to be executed in parallel is large, the long-word instruction is used. When it is small, the short-word instruction is used. A competition between the long-word instructions is detected by hardware and a competition between the short-word instructions only is detected by software. The simplification of the hardware brings about improvement of a machine cycle, improvement of a code cache hit ratio caused by the reduction of a code size and increase of the number of operations to be executed in parallel for the purpose of enhancing the performance.
