Abstract: A blower produces in the space (44) in front of the screen (41) an air pressure and thus an airflow through the opening (43) into the mixing chamber (23). At the same time, gas flows out of the annular gas outlet (49) to the periphery of the airflow and out of the outlet openings (25) into the centre of the airflow. After practically noiseless ignition by the electrodes (45) in the mixing chamber (23), a short and stable flame is produced at the end of the mixing head (11). With a relatively strong air supply, the air pressure at the gas outlet openings (25) throttles the central gas emission in favour of the peripheral gas emission from the gas outlet (49). This contributes to the stability of the flame. The annular space (19) serves for recirculation of hot combustion gases to the inlet (13). <IMAGE>

Abstract: A bipolar transistor having a silicon oxide film (19) having a stoichiometric composition ratio of silicon to oxygen controlled to 1 to 2 formed at the boundary between a monocrystalline layer (17) and a polycrystalline layer (20). In fabrication, a natural oxidized film (204) formed on the surface of an intrinsic base region (17) of a single-crystal is removed in an ultrahigh-vacuum chamber (101). Subsequently, oxygen ions are supplied to the surface of the base region (17) at room temperature to form a silicon oxide film (19). Further, silicon molecular beams are suppled in the same chamber (101) to form the polycrystalline silicon layer (20). The current gain factor h FE  of the bipolar transistor thus formed can be greatly improved.

Abstract: Polymers containing glutarimide units are useful in compatibilizing blends of two or more polymers to improve physical properties, especially modulus and heat distortion values. The polyglutarimides are especially useful when the polymers to be blended are incompatible with each other, but separately compatible with the polyglutarimide. Compatibilization with the polyglutarimide may be enhanced in some cases by a grafting reaction between the polyglutarimide, if it also contains acid or anhydride functionality, and one or more of the polymers to be blended.

Abstract: A method of detecting the presence of substances in tissue from a subject comprises non-invasively removing tissue particulates from the exterior of the subject, eg. by vacuum collection of desquamated skin particles. The tissue particulates are then collected on a collection medium, for example filter paper, and subsequently analyzed to detect the presence of substances of interest. Such substances can be narcotics, explosives, etc. The substances sought may be detected by releasing them from the filter, for example by heating in an oven (4) to volatilize them, the vapour then being detected by means such as an ion mobility spectrometer (5).

The annular metal transition sleeve has one end placed at the jacket outlet, the opposite end at the positioning and signal transfer assembly. A first insulated electrical conductor in electrical connection with the cap electrode extends through the retainer access channel and through the annular metal jacket to the jacket outlet. Finally, the positioning and signal transfer assembly is associated with the transition sleeve outlet for providing fit-up for said sleeve and for conveying electrical signals from said conductor. The elongated annular metal transition sleeve is interposed between said jacket and said positioning and signal transfer assembly.

Abstract: An article (40), such as a piece of manufacturing tooling, is modified prior to use by treating a portion of its surface to be worn so that the treated surface (44, 46) worn more than a preselected amount has a different appearence than the treated surface (42) worn less than the preselected amount, using a treatment process in which the treated surface is at least as wear resistant as the untreated surface. In one approach, the surface is treated by implanting ions to a preselected depth. The ions are chosen so that the article substrate has a different colour at depth less than the preselected depth than does the substrate at depth greater than the preselected depth. After wear, the treated surface is visually inspected for colour variations that indicate wear to more than the preselected depth. The surface treatment can also be accomplished by ion implanting or ion beam mixing a previously deposited surface coating.

Abstract: The method and device are applied to a parallel computer which carries out parallel processing by transmitting and receiving messages among a plurality of processors. 
     In a memorizing step (50), various pieces of information are memorized such as an execution starting time, standby starting time for waiting for reception of the message, message number on reception of the message, processor number of the processor, the message and time when the message is received, message number on transmitting the message and message execution ending time. In a step of obtaining the maximum delay path, a last ending processor is identified in which execution was last ended, and the standby starting time for waiting reception of the message in the last ending processor, the message number of the last ending processor, the transmitting processor number and the message transmitting processor corresponding to the transmitting processor number are all searched for among the memorized information. 
     These searches are repeated from the last ending processor to a starting processor where execution of the parallel processing was started. Thus, the maximum delay path can be obtained, allowing recognition of where increased data transmission speed is needed.

Abstract: The stereochemistry of sialylation of an acceptor saccharide to obtain an α (2-3) or α (2-6) linkage is controlled to favor the α anomer by use of an aromatic ester of the sialyl reagent. The resulting intermediate α (2-3) and α (2-6) sialylated intermediate disaccharide blocks are useful in the synthesis of antigenic substances which can be used to raise antibodies useful in diagnosis and therapy, and can themselves be used as reagents in various applications. The preparation of the tetrasaccharide antigens corresponding to the 19-9 and sialyl-X antigens characteristic of malignant tissue illustrates the application of this method.
