Abstract: ABSTRACT OF THE DISCLOSURE          Complementary MOS field effect transistor circuits are produced in silicon gate technology, with the method steps up to the structuring of the gate electrode being executed in a known manner.          Both source/drain implantations occur with only one mask.  This mask, which is composed of silicon nitride, is utilized for the source/drain implantation 8 of the n-channel transistors.  The source/drain implant-ation for the p-channel transistors occurs without a mask and the oxide layer thickness, d6, over the source/drain regions of the n-chan-nel transistors functions as a masking layer.  An advantage of this process sequence is that switched capacitor structures can be simul-taneously produced whereby the oxide layer thickness, d4, over the polysilicon-1 level determines the thickness of the insulating layer, dcox, of the capacitor structures.  This technique is useful for manufacturing VLSI CMOS circuits in VLSI technology with and without switched capacitors.

Abstract: METHOD AND  APPARATUS FOR CONTINUOUSLY ATTACHING ELASTIC STRANDS TO DISPOSABLE           ABSORBENT PRODUCTS                             ABSTRACT      In this invention, a continuous elastic ribbon is fed to a diaper assembly station in a stretched condition while, at the same time, an adhesive is continuously applied to the elastic ribbon.  Simultaneously, absorbent batts, as well as webs of moisture-impervious backsheet material and moisture-pervious top-sheet material are fed to the diaper assembly station.          Further, and simultaneously, while the webs are traveling to the  assembly station, a release medium is applied to one of the said webs in selected areas thereof in a manner so as to overlie pre-determined, isolated portions of said stretched, elastic ribbon.  At the assembly station, the stretched elastic ribbon is adhered to the moisture-impervious backsheet web along por-tions of the elastic ribbon which intervene the selected areas of the web where the release medium is located.  After the ad-hesive has set up, the stretched elastic ribbon adheres to the moisture impervious backsheet between the release medium, and the elastic is severed in its unadhered areas, whereupon the unadhered portions become relaxed and inactive without af-fecting the functionality of the adhered portions in the ultimate assemblage.

Abstract: Abstract:   A two-level alternate mark inversion signal trans-mission system converts binary pulses of "1" and "0" into a pulse signal in which one has its polarity inverted at a period T and the other at a period ?.  The converted signal is then transmitted.  In order to facilitate an automatic gain control and the extraction of a timing signal in the receiver, even when the zero binary pulses have successively arisen, on a transmitting side, the alternate mark inversion signal is converted in the transmitter into a specified code (zero substitution), while in the receiver, the received signal is subjected to duobinary shaping whereby the zero substitution part of the signal is detected for removal by utilizing the rules of the zero substitution and the alternate mark inversion signal.

Abstract: Abstract:    A heat exchanger for transferring heat from stale air evacuated from a building to incoming fresh air employs a core made of a stack of spaced aluminum sheets that are joined along opposite edges in an alternate arrangement to define two separate sets of air passages for the respective outgoing and incoming flows, while providing good thermal contact between the two flows.  This contact is improved by generating a measure of turbulence in the air flows by forming the sheets with surface nodules.  The core is mounted in a frame that can be readily slid into a housing containing fans for generating the air flows.  In an alternative construction, each air flow can be caused to travel in series through two parts of each set of air passages, rather than in parallel.  This series arrange-ment has the advantage of reducing the temperature drop across any one part of the core below the total temperature difference between the inside and outside of the building. A machine is also disclosed for manufacturing such a core. It employs sliding tools for quickly forming lap joints between adjacent sheets to space them apart and form the sides of the air passages.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention is a green-emitting phosphor and a low pressure mercury vapor discharge lamp using this phosphor.  This phosphor has a monoclinic monazite-type crystal structure and comprises a phosphate of cerium, terbium, and possibly lanthanum.  It is significantly different from green-emitting phosphors of the prior art in that it further comprises at least one element selected from the alkali metals, fluorine, indium, and boron.  Because of the addition of these elements, the decrease in powder brightness of the present phosphor after heating in air at 600 °C (the temperature at which phosphors are heated during the baking step of lamp manufacture) is much less than for conventional green-emitting phosphors.  The decrease in brightness of the present phosphor after irradiation by ultraviolet light at 185 nm is also much less than for conventional phosphors.  It is accordingly most appropriate for use in discharge lamps.  The low pressure mercury vapor discharge lamp using the present phosphor is of high efficiency and has high color rendition.
