Abstract: Complementary Transistor Structure and Method for Manufacture Abstract Complementary, vertical bipolar NPN and PNP transistors are fabricated on the same monolithic semiconductor substrate which have matched high performance characteristics.  A method for fabri-cating such complementary devices is also provided. In the method, a barrier region of a first conduc-tivity type is formed on the surface of the mono-crystalline semiconductor substrate doped with a second conductivity type.  After an annealing heat treatment to drive in the doping ions of the barrier region, a collector region for one of the comple-mentary transistors of a second conductivity type is formed within the barrier region.  It is convenient to simultaneously form isolation regions of a second conductivity type in the substrate while forming the collector region.  A collector region of a first conductivity type is then formed in the substrate for the other of the complementary transistors.  The collector region for the other complementary transis-tor is formed within at least one other isolation region.  An epitaxial layer of semiconductor material doped with ions of the first conductivity type is then formed on the surface of the substrate. To provide improved PNP transistor performance, the P-type emitter for the PNP transistor is formed prior to a last drive-in treatment by forming a polycrystalline silicon layer on the exposed surface of the base.  The polycrystalline silicon is doped with a P-type dopant.  Thereafter the transistor structure is subjected to conditions whereby the doping ions contained in the polycrystalline silicon layer are driven into the epitaxial layer to provide a shallow emitter region without effecting disloca-tions in the silicon lattice of the epitaxial layer.

Abstract: LIQUID DEVELOPER COMPOSITIONS     Abstract of the Disclosure Disclosed is a developer composition which in use exhi-bits improved depletion characteristics and produces copies of high image density.  The developer comprises an organic carrier containing a pigment system, a charge control agent, and a "gelatex" which acts as a fixitive and a dispersant.  The gelatex comprises a carrier-insoluble vinyl polymer and a multiply-branched, vinyl polymer which physically entraps or entangles the carrier-insoluble polymer and is on the borderline of solubility in the carrier.  The gelatex component is present in the carrier as a stable dispersion and is substantially uniformly depleted as multiple copies are produced, resulting in a significantly reduced rate of image density deterioration as multiple copies are produced.

Abstract: ABSTRACT       A fluid is filled in a space between a cover and an outer casing, to which a plurality of vanes are attached, and there is disposed in the aforementioned space a partition which is formed with two fluid inlet ports.  An inner casing is sandwitched between the partition and the outer casing thereby to form a reservoir between the cover and the parti-tion, an inner torque transmitting chamber between the partition and the inner casing, and an outer torque transmit-ting chamber between the inner casing and the outer casing. One of the fluid inlet ports of the partition is made to have communication with the inner torque transmitting chamber, whereas the other fluid inlet port is made to have communica-tion with the outer torque transmitting chamber.  The two fluid inlet ports are opened and closed by means of two valves, respectively, which are preset at different temperatures.       The temperature-sensitive fluid coupler thus constructed can suppress noise while still reducing the power consumption.

Abstract: ABSTRACT     For filling tracks worn in roadways, roadmaking material, preferably asphalt, is simultaneously laid in two adjacent tracks and in the intermediate strip of roadway, for which purpose the old material of the marginal regions of the tracks is replasticized as well as that of the intermediate strip; should the old surface of the intermediate strip be higher than the outer marginal regions of the two tracks, the replasticized material of the intermediate strip is removed to approximately the same level as the outer marginal regions of the two tracks, the removed material is laid in the tracks and, finally, the exposed surface of the intermediate strip is roughened before the new material is laid.  Two stripping-laying apparatuses which are arranged at a distance from one another laterally of the working direction serve to fill the tracks and are connected together by a stripping element whose lower stripping edge is level with the front ends of the lower stripping edges of the stripping-laying apparatuses.          Should the surface of the strip of roadway between two adjacent tracks be higher than the outer marginal regions of these two tracks, levelling and roughening devices for the strip of roadway lying between the two tracks are arranged in the working direction in front of the laying apparatuses connected by the stripping element.

Abstract: ABSTRACT An apparatus for decelerating the drive to a winding device for strip-material, having a length meter for the wound strip and a speed indicator for the strip to be wound, includes a computer which is adjustable to the nominal length of the strip of material and which brings the drive to a halt, at a predetermined rate of deceleration, as a function of the nominal length and of the instantaneous speed of the strip.  The rate of deceleration is determined by two different curves, one of which would produce less, and the other more, than the nominal length if one or the other of these curves were to be exclusively effective after commencement of deceleration.  The computer adjusts the rate of deceleration, in constant alternation, in accordance with the curves, changing over from one to the other as soon as it determines that the nominal length will be exceeded or not attained at the instantaneous pre-vailing rate of deceleration.
