Abstract: Lateral Device Structures Using Self-Aligned Fabrication Techniques Abstract Submicron lateral device structures, such as bipolar transistors, Schottky Barrier diodes and resistors, are made using self-aligned fabrication techniques and conventional photolithograph.  The devices are made using individual submicron silicon protrusions which extend outwardly from and are integral with a silicon pedestal therefor.  Both PNP and NPN transistors may be made by diffusing appro-priate dopant material into opposing vertical walls of a protrusion so as to form the emitter and collec-tor regions.  The protrusions themselves are formed by anisotropically etching the silicon using sub-micron insulating studs as a mask.  The studs are formed using sidewall technology where a vertical sidewall section of a layer of insulating material is residual to a reactive ion etching process employed to remove the layer of insulating material.

Abstract: Abstract of the Disclosure This invention relates to the formation of tubular objects by spirally winding and seaming a relatively rigid strip of plastics material.   In the prior  form of this rigid plastic strip,  it was difficult to control and change the diameter of the resulting the due to the forces required to overcome the extreme frictional engagement between the interlocking portions of  that prior  art  strip.   This invention provides a sealing flap (15, 215) along one longitudinal edge (5, 25) of the strip, and an engaging surface (16, 216) along the other edge (11, 211) positioned close to but separate from the interlocking portions  (8  and  12,  28,  212)  of  these  longitudinal  edges.    The provision of these  sealing flaps and engaging surfaces permit the interlocking portions at the edges to be designed independent of the ability of the these interlocking portions to create a fluid seal. This results in optimum operation of these interlocking portions to, for example, permit relatively rapid changes in the diameter of the tube as it is formed, as well as subsequent to its formation.

Abstract: ABSTRACT         An atrial-ventricular demand pacemaker having improved atrial pulse artifact rejection includes a blanking circuit connected in the signal path from the ventricular output terminal to the sensing amplifier to blank the signal during an atrial pulse.  A holding circuit including a low-pass filter and a switching element stores a prior signal value at the sensing amplifier input during the blanking interval, and delays return to normal operation until after the blanking circuit has returned to normal.  Artifact rejection is also improved by limiting atrial pulse output circuit recharge time and by limiting polarization current driven into the ventricular output circuitry by an atrial output pulse.

Abstract: ABSTRACT OF THE DISCLOSURE The apparatus for enveloping and packaging widely varying articles has a conveyor bet, to whose starting area are preferably supplied two foil webs, between which are located the articles to be packaged. Both between the articles and laterally, welds are produced by welding members, which are arranged on a three-dimensional frame, which can be moved up and down by means of a first crank drive (eccentric disk), in order to bring about the actual welding, which not only ensures the formation of a joint, but also constitutes a separation weld. The welding members are connected to the three-dimensional frame by a slide, which can be moved backwards and forwards in the feed direction and, in opposition to the feed direction of the conveyor belt on the frame, by a second crank drive (essentially) formed by a crank web, a link and a connecting rod). This ensures a synchronous movement of the welding members with the foils and articles, during the welding process. The two crank drives are jointly driven, the conveyor belt moves somewhat faster than the speed at which the foils are supplied, in order to further increase the separation of the individual packs produced by the separation weld. The apparatus operates continuously, i.e. without interruption, there being no stopping of the conveyor belt during welding.      (Fig 1).
