Abstract: Disclosed is an injection port assembly for subcutaneous delivery of medication. A single moulded body (11) has a soft flexible cannula (14) extending downwardly from a generally flat bottom surface and a self-sealing septum (22) mounted at the centre of a top surface which is generally of a concave shape sloping downward towards its outer perimeter at which point the single body is very thin. The single body (11) also has a tubular extension (12) which is directed outward parallel to the skin's surface. A metal needle (8) which penetrates through the septum and through the lumen of the soft cannula is used for inserting the cannula through the skin. The distal section of the needle has an external shoulder which engages an internal shoulder in the cannula so that the cannula will be in tension during insertion thereby preventing an accordion-like compressional failure of the cannula. A quick-release connector on the proximal end of the tubular extension or mounted directly on the injection port assembly allows the tubing connecting the injection port assembly to a portable medication pump to be disconnected when the patient showers or performs some similar activity.

Abstract: At least one certain primary or secondary color is established that receives special treatment for at least one printing medium. Such treatment may include (1) using more than two drops of primaries per pixel for binary printing of a particular secondary; or (2) binary-printing the chromatic primary or secondary -- but not other hues -- after rendition, by use of a "superpixel"; or (3) application of, in effect, a nonintegral number, greater than one, of ink drops per pixel; or (4) combinations of these treatments. As an example of the first of these treatments -- using inks optimized for plain paper at one drop of ink for primaries and two (one of each of two primaries) for secondaries -- red is printed on transparency film as one drop of yellow ink and two of magenta in each pixel. As to the second treatment, the superpixel is preferably a group of pixels ( e. g. , a two-by-two array) including the target pixel, in which group each pixel is inked and at least one pixel receives at least two drops of ink. In particular -- still assuming inks optimized for plain paper as described above -- to print red on so-called "glossy media" (meaning nontransparent glossy media), one drop each of yellow and magenta is used in each of two opposite corners, and one drop of yellow and  two  drops of magenta are used in each of the remaining corners. Analogously, to print green on transparency film, one drop each of yellow and cyan is used in each of two opposite corners, and one drop of yellow and  two  drops of cyan are used in each of the remaining corners; and to print blue on transparency film one drop each of magenta and cyan is used in two opposite corners, and one of magenta and  two  of cyan are used in remaining corners.

Abstract: An IDC termination machine (20) comprises opposed spring loaded gripper pads (62,54) for clamping and a wire to be terminated in alignment with a corresponding IDC section of a connector (2). One of the gripper pads (62) is connected to an arm (64) having a camming protrusion (70) that cooperates with a stuffer member (74). During pulling of the wire between the gripper pads (54,62), the gripper pads (54,62) are biased apart such that the wire can be brought without resistance as close as possible to the connector. Termination is then actuated, and advance movement of the stuffer (46) cams the protrusion (70) into a recess (100) of the camming plate (74). The gripper pad (62) thus clamps the wire against opposing gripper pad (54) just prior to cutting and termination.

Abstract: Modified chimaeric antibodies, and antibody heavy and light chains, which comprise variable domains derived from a first mammalian species, usually mouse, and constant domains from a second mammalian species, usually human. Modification concerns the variable domains, in particular the framework regions of the variable domains. The modifications are made only in T-cell antigenic structures present in framework regions, and do not cover canonical structures or Vernier zone. The modifications adapt the amino acid sequences concerned to those occurring in corresponding antibodies derived from said second mammalian species. Thus, the modified chimaeric antibodies retain the original antigen recognition and binding properties but become less immunogenic to said second mammalian species, which improves their therapeutical utility with said second mammalian species. Recombinant DNA technology may be used to construct and produce the modified chimaeric antibodies.

Abstract: In a microprocessor, an apparatus is included for coordinating the use of physical registers in the microprocessor. Upon receiving an instruction, the coordination apparatus extracts source and destination logical registers from the instruction. For the destination logical register, the apparatus assigns a physical address to correspond to the logical register. In so doing, the apparatus stores the former relationship between the logical register and another physical register. Storing this former relationship allows the apparatus to backstep to a particular instruction when an execution exception is encountered. Also, the apparatus checks the instruction to determine whether it is a speculative branch instruction. If so, then the apparatus creates a checkpoint by storing selected state information. This checkpoint provides a reference point to which the processor may later backup if it is determined that a speculated branch was incorrectly predicted. Overall, the apparatus coordinates the use of physical registers in the processor in such a way that: (1) logical/physical register relationships are easily changeable; and (2) backup and backstep procedures are accommodated.

Abstract: An emission layer (5) for a light source device is formed to have a multi-layer structure, doped with an acceptor and a donor impurity. The multi-layer structure may include a quantum well (QW) structure or a multi quantum well (MQW) structure (50). With such a structure, a peak wavelength of the light source can be controlled, because the distances between atoms of the acceptor and the donor impurities are widened. Several arrangements can be made by, e.g., altering the thickness of each composite layer of the multi-layer structure, altering their composition ratio, forming undoped layer 5 between the impurity doped layers, and so forth. Further, luminous intensity of ultra violet color can be improved, because doping the donor impurity and the acceptor impurity realizes a donor-acceptor emission mechanism and abundant carriers. Several arrangements can be made by, e.g. optimizing the materials of the composite layers, optimizing their composition ratios, optimizing their lattice constants, and so forth to further enhance the luminous intensity of the light source.

Abstract: A semiconductor device having a concavity formed by LOCOS technique, in which defects induced due to the LOCOS oxidation step or a following heat-treatment step are suppressed, is disclosed. An n +  type region (31), the impurity concentration of which is caused to be 1 x 10 19  cm -3  or more, is formed in an n -  type semiconductor layer (2). By means of this, defects (61, 62) occur within the n +  type region (31) or in a proximity of the boundary of the n +  type region (31) and the n -  type semiconductor layer (2). The defects (61) and (62) trap contaminant impurities taken into the wafer during the manufacturing steps, and cause contaminant impurities existing in the proximity of a concavity of the semiconductor layer (2) surface to be reduced. As a result thereof, defect occurrence in the proximity of the concavity can be suppressed, and occurrence of leakage and degradation in breakdown voltage between drain and source accompanying defect occurrence in a channel region can be suppressed.
