Abstract: FIELD EFFECT TRANSISTOR HAVING  IMPROVED THRESHOLD STABILITY     Abstract of the Disclosure An improved field effect transistor device in a monocrystalline semiconductor body provided with source and drain regions and a gate electrode disposed over the channel between the source and drain regions wherein at least the drain region is formed of a first region where the impurity concentration increases with depth with the peak concentration being spaced inwardly from the major surface, and a second region located within the first region having a peak impurity concentration at the major surface.  The drain region structure in operation promotes the current flow between the source and drain to flow deeper in the channel region and spaced from the gate dielectric layer.         In the method for forming the field effect transistor, an impurity is introduced into the semi.-conductor body underlying at least the ultimate drain region, an epitaxial semiconductor layer deposited, and a second impurity region formed over the first region to form the drain contact.         In an alternate embodiment of the method for forming a field effect transistor, a first ion implanta-tion is formed in the drain region, such that the peak impurity concentration is located well within the body spaced from the surface thereof, and a second ion implantation, or diffusion, performed forming the source and also the ohmic contact for the drain which is located over the first region and within the first implanted region.

Abstract: Abstract of the Disclosure There is disclosed a method for the disposal of sewage from a plurality of household connections.  A specific volume of sewage, for example 5 to 30 litres, is first collected from each house and then suctioned off by vacuum.  Air is then released into the vacuum pipe in an amount of 2 to 15 times the volume of the sewage.  This system permits operation of sewage removal against gravity in locations with unfavourable natural incline.  The relatively large volume of air used compared to the small increments of sewage disposed enables improved conveyance capacity even with comparatively narrow pipes.

Abstract: ABSTRACT OF THE DISCLOSURE          An acoustic lens for marine doppler sonar apparatus of the type in which acoustic energy is radiated and received along a beam directed at an angle with respect to a ship's axis is fabricated so as to have an external surface substantially flush with the ship's hull and an internal surface angularly disposed with respect to the external surface.  Electro-acoustic transformation elements are mounted on the internal surface.  The lens material is selected to have an acoustic propagation velocity greater than that of water so that acoustic signals are refracted in passing across the lens-water interface.  The lens prevents spurious acoustic signals that would ordinarily be reflected from the aerated water close to the ship's hull from reaching the electro-acoustic transformation elements.

Abstract: ABSTRACT:              A method of manufacturing a dispenser cathode in which a porous sintered molding of refractory metal impregnated with electron emissive material is embedded in a holder.  The method consists of placing the molding in contact with a flat metal foil having a thickness of 10 to 100 microns and mechanically forming the metal foil into a holder surrounding the sides and the rear of the molding while leaving the front surface of the molding exposed by pressing the molding through an apertured die by means of a pressing tool.  The molding acts as a plunger to draw the metal foil over the molding such that any gap between the molding and the sidewall of the holder is less than 10 microns wide.
