Abstract: MULTILUMEN CATHETER                      Abstract A multilumen catheter having passages for the flow of gas, the enclosure of electrical leads, and the transmission of fluids for injection and sampling.  The gas transmitting lumen also carries the electrical leads which extend to an electrical element disposed within a passage-providing plug located at a point spaced from the catheter's distal end.  The plug blocks the entry of fluids into the catheter without at the same time interfering with the flow of gas therethrough.  In one embodiment, the passage-providing plug is at least partially pre-formed and is fitted into the space other-wise occupied by sections of a pair of adjacent lumens, thereby allowing a relatively large electrical element to be mounted within such space; in a second embodiment the element is mounted in a passage-providing plug disposed within a single lumen; and in a third embodiment the element is embedded in a passage-providing plug which is formed in place.  Methods for making such catheters are also disclosed.

Abstract: GO/NO GO MARGIN TEST CIRCUIT FOR SEMICONDUCTOR MEMORY     ABSTRACT     A semiconductor memory circuit (140) includes a plurality of memory cells each having an access transistor (154, 158) and a storage capacitor (162, 166).  The memory cells are connected to digit lines (142, 144) each of which is split into halves each connected to one input of a sense amplifier (146, 148).  The sense amplifiers (146, 148) operate to pull one of the half digit lines connected thereto to ground while a pull up circuit (220) operates to elevate the other half digit line to the supply voltage.  A margin test circuit receives through a control pin (236) an externally supplied test command which generates a test signal (318) to generate marginal low and marginal high voltage states to be written into the memory cells.  The marginal low voltage state is generated by a voltage divider (288).  The marginal high voltage state is generated by disabling the pull up circuit (220).  To prevent loss of the marginal low state the sense amplifiers (146, 148 and 248) are disabled by the internally generated test signal.  While the externally supplied test command is applied to the semiconductor memory circuit (140) marginal voltage states are applied to memory cells in accordance with externally supplied address and operational commands.  The marginal voltage states are utilized to simplify testing of the circuit.

Abstract: A PACKAGE FOR A SEMICONDUCTOR CHIP            Abstract A package for a semiconductor chip includes as an integral part thereof a frame-shaped multilayer ceramic capacitor.  The chip is mounted within the capacitor structure.  Conductive portions of the capacitor serve as the terminals and plates of the capacitor and as planar power and ground members for interconnecting an external power supply to the chip.  By means of these planar members, power is distributed to the chip in a low-impedance, substantially transient-free manner without utilizing any of the multiple signal leads emanating from the package.  Moreover, the signal leads are separated from the ground plane by a low-dielectric-constant material.  As a result, the signal leads are minimally loaded and are characterized by a relatively constant impedance selected to optimize signal transfer to and from the chip.
