Abstract: ABSTRACT   An avalanche photodiode has a light absorbing semiconductor layer and an avalanche gain semiconductor layer having a bandgap greater than that of the light absorbing semiconductor layer.  A first p-n junction having a substantially p+-n junction is selectively provided in the avalanche gain semiconductor layer.  A second p-n junction having a substantially graded p-n junction surrounds the periphery of the first p-n junction.  A third p-n junction having a substantially graded p-n junction surrounds the periphery of the second p-n junction.  A specific feature of the invention is that the second p-n junction is positioned deeper from the upper surface than the first p-n junction and the third p-n junction is positioned closer to the upper surface than the second p-n junction.  The photodiode of the invention is capable of achieving sufficient and uniform avalanche gain in a stepwise p-n junction region corresponding to its light receiving region before a voltage breakdown occurs in its guard ring.

Abstract: ABSTRACT OF THE DISCLOSURE A CRT display unit comprises a line mode detecting circuit for determining a standard mode or a high-resolution mode dependent on the output of a counter counting a horizontal synchronizing signal. When the high-resolution mode is determined, a switching circuit enables a horizontal oscillator and a horizontal deflecting circuit to operate corresponding to the high-resolution mode. In other words, the switching circuit selects time constants so as to increase a horizontal oscillating frequency of the horizontal oscillator. To a collector of a horizontal deflecting transistor, two capacitors are connected so that a horizontal flyback period may be shortened. An end of a horizontal deflecting coil is connected to a step-down transformer so as to increase a horizontal amplitude. Thus, the horizontal oscillating frequency, the horizontal amplitude and the horizontal flyback period can be automatically set according to each mode.

Abstract: TITLE      Differential Pressure Capillary Viscometer for Measuring Viscosity Independent of Flow Rate and Temperature Fluctuations ABSTRACT OF THE DISCLOSURE          A means for measuring either the intrinsic or inherent viscosity of a solute in solution with a solvent which is independent of flow rate and temperature fluctuations.  The solution is passed through one capillary tube and the solvent through a second capillary, and the pressure drop across each is measured.  Signals corresponding to each pressure drop measurement are fed to an amplification means such as a logarithmic amplifier where they are processed to determine either the intrinsic or inherent viscosity of the solute independent of flow rate and temperature fluctuations.  The viscosity measuring means may also be used together with size exclusion chromatrography to determine the molecular weight distribution of polymer materials.  It may also be used to measure the relative viscosity of a sample liquid and a reference liquid, and to determine the viscosity of the sample liquid independent of flow rate and temperature fluctuations.

Abstract: PIPELINE,  METHOD OF PIPELINE LAYING, AND A MACHINE FOR LAYING THE PIPELINE                       Abstract The proposed pipeline is made up of pipe sections connected in succession by elastic outer coupling elements brought into intimate contact by the entire surface thereof with pipe section joints. Provided at the ends of the pipe sections are recesses for accommodating joint elements therein. The method for laying the above pipeline involves successive joining of its pipe sections by means of con-tinuously placing several layers of a binder-impregnated tape onto the joints. The pipeline is lowered into trench before the binder sets. The machine for carrying out the method includes a self-propelled carriage with a frame on which there is mounted a mechanism for connecting, pressure--sealing, and insulating pipe sections of the pipeline.          This mechanism is arranged at an angle to the path of travel of the carriage to be capable of reciprocating and rotating relative to the pipe sections being joined into a pipeline.

Abstract: FLUID BED HOG FUEL DRYER                 ABSTRACT OF THE DISCLOSURE       A fluidized bed process and apparatus for uniformly drying particulized wet wood material or waste, commonly called hog fuel, from in excess of 50% moisture content to a 30% level suitable for burning as boiler fuel without generating "blue haze" air pollution typical of conventional rotary dryers. The fluidized bed of this invention is divided into treatment zones by a baffle arrangement. The hog fuel flows substantially horizontally along a circuitous path through the treatment zones. Hot flue gases fluidize the bed of hog fuel and provide necessary drying heat. Fines portions from each zone are entrained by the drying gases and blown out of the vessel just as they achieve the desired level of dryness and before significant blue haze is generated. A cyclone recovers these fines as product. Gas pressure to each treatment zone is adjusted so that only the desired amount of hog fuel is blown from the bed with the balance proceeding to subsequent zones.          Regulation of zone gas velocities is achieved by dividing the gas inlet plenum into compartments which coincide with zones requiring adjusted velocities. The dryer may use flue gas from a hog fuel boiler, and in turn dry the hog fuel being burned in that boiler, or it may use the hot gas from an independent combustion source. A particularly attractive arrangement is to mount the fluid bed dryer above a fluid bed combustor burning waste wood in a single vessel.

Abstract: ABSTRACT           A machine for transferring metered quantities of viscous materials from a source of such materials into successive receptacles has a tubular housing with inlets and outlets disposed diametrically opposite each other.  The housing confines a rotary metering device having an axially extending chamber and an opening which communicates with the inlet in one angular position and with the outlet in another angular position of the metering device.  A piston in the metering device draws flowable material from the source into the chamber in the first angular position and expels such material from the chamber into a receptacle in the second angular position of the metering device.  The housing and the metering device have adjacent frustoconical surfaces and the metering device is movable axially to establish between such surfaces a frustoconical clearance for admission of a liquid or gaseous cleaning fluid while the metering device remains in the interior of the housing.  Additional cleaning fluid can be admitted into the metering device in the region of its opening as well as into the inlet of the housing.                             -?-

Under the pressures and temperatures described, the organotin  compounds  become  pentacoordinated  and linked through the electronegative bridges, forming polymers within the light hydrocarbon flooding media to render them highly viscous.  Under ambient conditions, the viscosity control agents will not readily be produced from the formation with either crude oil or water, since they arc insoluble in the former and only sparingly soluble in the latter.
