Abstract: In six different measuring configurations, a pulse voltage is impressed on the wires of the subscriber line while the other wire is respectively earthed and the respective pulse response is measured or these wires are again discharged to earth and the discharge voltages measured at discrete times. In each case prior to analog-digital conversion, which precedes the digital measured value evaluation, a value of the difference between the initial voltage value occurring at the start of the discharging process and the respective measured value occurring at a discrete measuring time is formed and subjected to amplification in order to obtain from the measured values an appropriate pattern in the discharge curve, even in the case of lines with a large time constant, from which the line parameters are then calculated. <IMAGE>

Abstract: A method for adjusting conditions comprises the steps of, when a radiation image of a specific object is recorded and read out, investigating whether recording and read-out operations were or were not carried out in the past for the same object as the specific object. When recording and read-out operations were carried out in the past for the same object as the specific object, image recording conditions for the specific object are adjusted such that they coincide with those under which the recording operation was carried out for the same object as the specific object. Also, instead of read-out conditions for a final readout, which is to be carried out for the specific object, being adjusted on the basis of a preliminary read-out image signal representing the radiation image of the specific object, the read-out conditions for the final readout to be carried out for the specific object are adjusted such that they coincide with those under which the final readout was carried out from the radiation image of the same object as the specific object. Recording and read-out operations for the specific object are carried out under the conditions, which have thus been adjusted.

Abstract: Disclosed here are D-type flipflops cascaded in a semicustom LSI such as a standard cell or a gate array. Clock signals supplied to each of the flipflops have phases different from each other due to clock skew. A signal indicative of a data signal holding in the flipflop in one stage is applied to the flipflop in the preceding stage. The flipflop in the preceding stage is responsive to the applied signal for allowing a data signal held in a master latch to be transmitted to a slave latch. As a result, the passing through of data which might be possibly caused by the clock skew can be prevented. In other words, the passing of a data signal through two flipflops during one clock cycle can be prevented.

Abstract: Miniature high pressure arc lamps containing a substantial pressure of xenon, in addition to metal halide and mercury, can provide instant light at turn-on and are suitable for automotive headlamps. The xenon aggravates convection which causes arc-bowing and overheating of the envelope above the arc. By operating the lamps on unidirectional current upon which a frequency-modulated high frequency ripple has been imposed, acoustic resonance is used to straighten out the arc. The use of unidirectional current permits a reduction in cost and size of the ballast control circuits operated from auto storage battery. Frequency modulation of the ripple broadens the band allowing acoustic straightening of the arc. Additional control of the arc plus reduction of cataphoresis may be achieved through a horizontal magnetic field at the arc, transverse to current flow.

Abstract: Disclosed is a method for fabricating complementary heterojunction bipolar transistors on a common substrate. The method comprises the steps of depositing a PNP profile (14) by molecular beam epitaxy on an appropriate substrate (12) and then depositing a layer of silicon nitride (16) on the PNP profile just deposited. The substrate is then heated in a vacuum in order to densify the silicon nitride. A mask (20) and resist layer (18) are used to produce the desired PNP profile patterns. The NPN profile (22) is deposited on the area of the substrate (12) etched away as well as on the silicon nitride layer (16) protecting the already deposited PNP layers. The NPN profile (22) is then patterned using a resist (24) and masking process. The polycrystalline NPN area on top of the silicon nitride layer and the remaining silicon nitride layer are etched away forming two adjacent complementary NPN and PNP profiles on a common substrate. In the fabrication of the heterojunction bipolar transistor circuits, the P-ohmic contacts on both the NPN and PNP materials is evaporated at the appropriate locations simultaneously. All of the N-ohmic contacts are also deposited simultaneously. By this, the complementary dual heterojunction bipolar transistor device can be effectively fabricated with excellent DC and microwave capabilities.

Abstract: A surgical stapling instrument (50) for performing a circular anastomosis stapling operation is provided. The surgical instrument includes a stapling head assembly (60) mounted by a curved shaft (70) to an actuator handle assembly (80) and incorporates an improved actuator mechanism for transmitting the required operating forces and movements from the actuator handle assembly through the curved shaft to an anvil (100) and staple driver (62) of the stapling head assembly. The stapling head assembly includes a longitudinally movable trocar (73) detachably secured by one or more retainer clips (110) on a hollow shaft of the anvil. When the trocar is retracted, the anvil shaft slides into a central support tube (66) which aligns the anvil axially and circumferentially with a staple holder on the stapling head assembly. The retainer clips are locked against the trocar by the support tube and transmit tension from the trocar to the anvil with no tension load on the anvil shaft. The actuator mechanism permits adjustment of the anvil gap to produce a desired staple height and precludes actuation of the staple head assembly if the anvil gap is set outside of a predetermined range. Also, the actuator mechanism is adapted to both advance and retract the staple driver relative to the staple holder in the stapling head assembly. Further, an improved arrangement for attaching the support shaft to the stapling head assembly and to the actuator handle assembly is provided.

Abstract: Offset between a pair of images is determined using parallel processing techniques in a general-purpose digital serial processor. For each image, a patch of pixels is selected and convolved with a Laplacian kernel. The result is convolved with a Gaussian kernel in each of the x- and y- directions to produce a registration image. The registration images are binarized, bit-packed, and correlated to one another by performing an EXOR operation for each pixel location at each of a plurality of relative offsets of the images. The results of the EXOR operation are summed to produce an image-correlation value for each relative offset. The image-correlation indicating highest correlation determines relative offset of the images. The determined offset can be used for a variety of purposes in automating control of E-beam and FIB systems, to register images to one another or to identify a location in one image which corresponds to a selected location of the other image.

The new socket structure is created for every endpoint. All the protocols which could potentially be used to send or receive data is sent a request to create a protocol control block at the time the new socket is created. A selection process determines which of the protocols could be used by the endpoint. The new socket then contains information on each selected protocol. At the time a connection is established, any of the selected protocols could be used. The choice of which protocol to use can be based on user preferences, which protocols are available, the name of the service unit.
