Abstract: ABSTRACT OF THE DISCLOSURE         A method for manufacturing a CMOS circuit wherein a process sequence matched to an n-tub manufacture is carried out.          Short-channel properties of n-channel transistors are improved by performing double boron implantations of the channel regions.      A shared channel implantation is executed for both transistor types.  Compared to traditional CMOS processes in n-tub structure, this eliminates involved masking steps.  Also, the polysilicon gate is shielded from the boron ion implantation by means of a masking re-oxidation step and the under-diffusion given n-channel an p-channel transistors is greatly reduced by means of pull-back of the boron source/drain implantation.          This contributes significantly to a symmetrical UT behavior of the transistors and to the attainment of high switching speeds.          The method is used in the manufacture of VLSI CMOS circuits in VLSI technology.

Abstract: ABSTRACT OF THE DISCLOSURE             An  automatic  water-sprinkling  controller  has  a  special main-valve   connected   with   water   supply   for   controlling   a water-sprinkling  system,  which  includes  sprinklers,  hose  or  pipes connected between said main-valve and said sprinklers, and a pilot tube for operating said main-valve.   In the automatic controller, when the shortage  of  water of  the  ground  is  sensed  by  a  moisture  sensor comprising  a ribbon which expands  and  contracts  with  humidity,  a microswitch is turned on by the contraction of the ribbon to feed an electric current to an electronic circuit and to start a timer circuit. The electric current is instantly fed to a solenoid, which is mounted in a microvalve unit, to open this unit, through the electronic circuit. When the microvalve is opened, pilot water in the pilot tube, which is connected between the microvalve and the main-valve, starts to flow, and the  main-valve  is  opened.    These  open  states  are  held  for  a predetermined time period so that the  sprinkler  of  the  system can automatically perform  its  water-sprinkling  operation  for  that  time period.

Abstract: ABSTRACT OF THE DISCLOSURE                 The present invention provides an improved process for molding thermotropic liquid crystalline polymer, and the apparatus for such process.  The process comprises the steps of providing a molten stream of the polymer to be molded; injecting said molten stream into the cavity of the mold; allowing a portion of the melt to flow out of the cavity so as to substantially preserve the laminar flow pattern of the melt in the cavity; and solidifying the molten polymer into a molded article.  The resulting articles have mechanical properties superior to conventionally molded articles.

Abstract: A FLUID LEVEL CONTROL SYSTEM  Abstract of the Disclosure A fluid level control system is disclosed which uses pressurized air from a turbocharged engine to regulate the level of fluid in an axle assembly and for returning excess fluid from the axle assembly to a transmission case.  The system includes a fluid supply line and a fluid return line connecting the transmission case to the axle assembly.  A pump is positioned across the fluid supply line to supply pressurized fluid to a hydraulic actuator which is located within the axle assembly. The hydraulic actuator, such as a clutch for a differential, is susceptible to leaking fluid which can raise the fluid level in the axle assembly. A standpipe is positioned within the axle assembly and has a first end connected to the return line and a second open end located approximately even with a predetermined static fluid level.  The system also includes an air intake line connecting the turbocharger to the axle assembly and has an orifice positioned thereacross for limiting the rate of flow of pressurized air which is directed therethrough.  The orifice also assures that the efficient performance of the turbocharger is not detrimentally affected.  In order to assure that any excess fluid within the axle assembly is routed to the transmission case, the pressurized air must be of sufficient value to overcome any head difference present between the fluid level at the second end of the standpipe and the outlet of the return line.  There should also be sufficient air pressure to overcome any restrictions which may exist in or across the return line.

Abstract: ABSTRACT         The method of this invention yields a two phase liquid aqueous system which replicates the two phase heterogeneous physicochemical system of naturally occurring whole human blood.  The method produces a composition of matter which comprises a whole blood substitute when polymerized hemoglobin ox pyridoxylated-polymerized hemoglobin, and preferably, other specific additives are incorporated.  When said blood substitute is processed further, a microencapsulated composition with time release characteristics that can transport oxygen is produced.  The invention overcomes the obstacles that have prevented the use of modified hemoglobins like pyridoxylated-polymerized hemoglobin in the preparation of oxygen transport systems.

Abstract: ABSTRACT     An outside air supply control apparatus for a fireplace comprising a first cylindrical pipe for connection to an outside air supply, the pipe containing at least one aperture in its wall.  A second cylindrical pipe having an inside diameter slightly larger than the outside diameter of the first pipe, and having a closed end, is disposed coaxially over the end of the first pipe.  The second pipe has an aperture in its wall which can overlap the aperture in the wall of the first pipe when rotated to a first position, and has an unapertured portion which can completely block the aperture in the wall of the first pipe when rotated to a second position.  Preferably the apparatus includes a closed end cylindrical cap having an inside diameter which is much greater than the outside diameter of the second pipe, disposed concave down over, and being fixed to the second pipe, whereby the second pipe can be rotated upon rotation of the cap and whereby outside air passing through coincident apertures in the pipes is deflected downwardly.  Thus the cap both deflects the air and stops any ash or burning debris from passing through the coincident apertures.  Yet the amount of air supplied to the fire can be controlled to a very fine degree by rotating the cap.
