Abstract: HIGH PERFORMANCE BIPOLAR DEVICE AND METHOD FOR MAKING SAME         Abstract A method for manufacturing a high performance bipolar device and the resulting structure which has a very small emitter-base spacing is described.  The small emitter-base spacing, reduces the base resistance compared to earlier device spacing and thereby improves the performance of the bipolar device.  The method involves providing a silicon semiconductor body having regions of monocrystalline silicon isolated from one another by isolation regions and a buried subcollector therein.  A base region is formed in the isolated monocrystalline silicon.  A mask is formed on the surface of the silicon body covering those regions designated to be the emitter and collector reach-through regions.  A doped polycrystalline silicon layer is then formed through the mask covering the base region and making ohmic contact thereto. An insulatinq layer is formed over the polysilicon layer.  The mask is removed from those regions designated to be the emitter and collector reach-through regions.  The emitter junction is then formed in the base region and the collector reach-through formed to contact the buried subcollector.  Electrical contacts are made to the emitter and collector.  The doped polycrystal-line silicon layer is the electrical contact to the base regions.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of constructing an impermeable wall in the ground having no joints is disclosed.  The method overcomes the problems of forming an impermeable joint between a series of individually dug slots.  The improvement includes excavating at least one portion of trench in the ground at a width and depth required for the wall, replacing excavated material from the trench with bentonite-water slurry, and after completing the excavation, replacing a predetermined amount of the bentonite-water slurry with cement.  The cement is mixed with the remaining bentonite-water slurry in the one portion of trench to produce an evenly mixed cement-bentonite-water slurry.  After this slurry has gelled, the above steps are repeated on adjacent portions of trench, and the completed trench then allowed to harden and form a single impermeable wall.

Title: Method and an arrangement for the manufacture  of casings
Inventor: PUPP HERWIG
IPC: B29C61/10
Filed: 1978-12-21
Granted: 1982-05-11
Abstract: ABSTRACT          In the packaging field certain types of packages are manufactured from pre-shaped, cylindrical casings made from a heat-shrinkable laminate. The casings are formed by winding a material sheet around a mandrel and subse-quent sealing together of the overlapping ends of the sheet. However, because of the stiffness of the material the leading end of the sheet protrudes tangentially from the mandrel during the winding and prevents an! accurate adaptation of the material sheet to the surface of the mandrel.         According to the method and arrangement of this invention this disadvantage is avoided in that the lead-ing end of the sheet is pre-heated on the side facing the mandrel to such a degree, that the shrinking is initialled. The shrinking of one side only results in that the leading end of the material sheet is given a curved shape with a radius that coincides with the radius of the mandrel, and consequently the leading end is no longer an obstacle to the winding.

In order to form a first-come first-served queue in an information transmission system employing a common transmission channel when several transmitters of the system try to gain access to the channel when it is already occupied, without employing a further transmission channel to a point at which an account is kept of the order in which the various transmitters request access, each trans-mitter which tries to gain access in these circumstances is caused to delay after the channel subsequently free before it actually accesses the channel, this delay being inversely proportional to the time the corresponding trans-mitter has waited. Thus the transmitter which has waited the longest gains the channel first and causes the other waiting transmitters to continue to wait.
