Abstract: A catheter tube is composed of a main portion 22 and a tip portion 23. The main portion 22 of the catheter tube is of such a structure that an inner tube 4 and an outer tube 6 are joined via a reinforcing material layer 5, but the tip portion 23 is of such a structure that only the inner tube 4 and the outer tube 6 are joined without intervening the reinforcing material layer 5 between the two tubes. The reinforcing material layer 5 is formed by arranging a filamentous element (e.g., stainless steel wire) 51 around the inner tube in a lattice manner. The inclination angles ϑ1, ϑ2 and ϑ3 of the filamentous element 51 with respect to the axis of the catheter tube at the first, second and third regions 221, 222 and 223, respectively are determined so as to establish the relationship as ϑ1 < ϑ2 < ϑ3. Therefore, the rigidity of the catheter 2 can be increased in accordance with the decrease of the inclination angle of the filamentous element 51. According to the catheter tube, excellent pushing, torque transmission, follow-up to a guide wire, and kink-resistant characteristics can be attained, simultaneously and respectively.

Abstract: The contact opening through an insulating layer is formed having a straight sidewall portion and a bowl shaped sidewall portion. The bowl shaped sidewall portion is near the top of the insulation layer to provide an enlarged diameter of the contact opening at the top relative to the bottom. A conductive material is then formed in the contact opening in electrical contact with a lower conductive layer. The conductive material forms a plug having an enlarged head, such as a nail head or a flat heat screw shape. The enlarged head protects the silicon and a barrier layer, if present, within the contact from being etched by any subsequent anisotropic etches. Thus, when an electrical interconnection layer such as aluminum is formed overlying the contact plug, the plug acts as an etch stop to prevent etching of a barrier layer of the barrier layer within the contact opening.

Abstract: A CMOS driver/receiver pair is provided which includes a non-inverting buffer in the input path to a differential receiver circuit. The non-inverting buffer allows a plurality of different voltages, and corresponding voltage swings, to be possible. This allows the differential receiver to compare the input voltage received from the transmission line with the output from its associated driver. Therefore, the receiver is capable of determining the voltage level (and the corresponding logic level) input from the transmission at the same time its associated driver is outputting a logic signal to another driver/receiver pair, via the transmission line. A single voltage source is utilized to provide multiple positive voltages to the differential receivers, such that differences in voltage levels which correspond to different logical combinations of "1" and "0" can be determined by the receiver.

Filed: 1990-07-30
Abstract: A highly efficient genetic cloning system is disclosed which is particularly useful for cloning cDNA copies of eukaryotic mRNAS and can direct the orientation of inserts in plasmid composite vectors with large cloning capacities. Cleavage of such vector DNA, by the restriction enzyme SfiI, for example, creates two different non-symmetrical 3' extensions at the ends of vector DNA. Using a linker-primer and an adaptor, cDNA is prepared to have two different sticky ends which can be ligated to those of the vector. When the cDNA fragments and the vector DNAs are mixed, both the molecules can assemble without self-circularization due to base-pairing specificity. This system provides (1) high cloning efficiency (10 7 -10 8  clones/g poly (A) +  RNA), (2) low background (more than 90% of the clones contain inserts), (3) directional insertion of cDNA fragments into the vectors, (4) presence of a single insert in each clone, (5) accommodation of long inserts (up to 10kb), (6) a mechanism for rescue of the plasmid part from a λ genome, and (7) a straightforward protocol for library preparation.
