Abstract: METHOD FOR IMPROVING DIELECTRIC BREAKDOWN STRENGTH OF INSULATING-GLASSY-MATERIAL LAYER OF A DEVICE INCLUDING                  ION IMPLATATION THEREIN                 Abstract of the Disclosure It has been discovered for the practice of this disclosure that a particular ion radiation treatment of amorphous SiO2 thin film, with a subsequent annealing procedure, improves the dielectric break-down property of the film.  The treated SiO2 film is found to be sub-stantially more dense than a comparable untreated SiO2 film.  It is theorized for the practice of this disclosure that the physical mechan-ism which produces the densification of the SiO2 film may be respon-sible for the enhanced dielectric properties of the film.  Such an im-proved film is especially useful as the gate insulator layer in an in-sulated-gate electrode field-effect transistor device, and as an insula-ting layer for electrically separating two metallic films in a thin film integrated circuit.  Such SiO2 thin films are useful in integrated circuit technology because the electrical insulation property thereof is considerably improved, e.g., in metal-oxide-semiconductor field ef-fect devices in which the gate insulation is relatively thin, e.g. less than 500.ANG., and in metallic magnetic-bubble devices in which a thin SiO2 layer is used to separate the sense element from the conductive magnetic film.

Abstract: Abstract of the Disclosure An analog signal representative of the condition of a process variable and an analog set point signal representative of the desired value of the process variable are compared to provide an analog error signal.  In response to the analog error signal the controller generates a sign signal and a pulse rate signal which can be utilized to increase or decrease the digital value stored in a counter from which a process control signal is generated.  In a preferred embodiment the process controller of the invention is utilized as a backup controller for a direct digital control system and utilizes the same digital output, digital to analog conversion, and analog output components as the associated direct digital controller.

Abstract: Abstract of the Disclosure An incoming diphase signal is decoded by an apparatus which includes a circuit for generating a clock control signal derived from the diphase signal and related to the clock which initially generated the diphase signal.  A controlled oscillator, the frequency of which is determined by the control signal, advances a counter having a plurality of distinct states.  A circuit is included, responsive to selected states of the counter, which serves to decode data information from the diphase signal.  The decoding circuit includes a first sampler for sampling the level of the diphase signal during a first preselected counter state and further includes a comparator for comparing the sampled diphase signal level with a subsequent diphase signal level.  This apparatus is particularly adapted to carry out the process which includes the steps of locking an oscillator to the clock frequency of the diphase signal and sampling the level of the diphase signal during the first half of each diphase base-bit interval.  The process further includes the steps of comparing the sampled base-bit level with the level of the diphase signal during the last half of the same diphase base bit interval and storing the comparison level.

Abstract: ABSTRACT OF THE DISCLOSURE      Tobacco smoke filters and methods and means for making same wherein the products have an elongated annular intermediate member overwrapped with a conventional plug wrap, with discrete inner plugs of a length shorter than the intermediate member and offering at least as much resistance to passage of smoke as the intermediate member, being secured within the intermediate member against axial displacement.  The inner member may be formed of a filtra-tion material, as is the intermediate member, or the inner member may be formed of a material which is non-permeable to smoke.  Portions of the intermediate member may be crimped to embed them into the inner member thereby is-proving the engagement between these members.  The inner member may be centrally positioned within the intermediate member to form cavities at each end of the filter or, alternatively, the inner member may be secured at one end of the intermediate member to provide only a single inner cavity.  The smooth outer surface of the intermediate member enables the attachment of a conventional plug wrap without the need for an internal glue line.  Means are dis-closed for cutting an inner rod to form a multiplicity of inner plug members, and then axially spacing the inner members from each other by injecting jets of air or the like between adjacent inner members.

Abstract: ABSTRACT OF THE DISCLOSURE      Thin-walled beryllium structures are prepared by plasma spraying a mixture of beryllium powder and about 2500 to 4000 ppm silicon powder onto a suitable substrate, removing the plasma-sprayed body from the substrate and placing it in a sizing die having a coefficient of thermal expansion similar to that of the beryllium, exposing the plasma-sprayed body to a moist atmosphere, outgassing the plasma-sprayed body, and then sintering the plasma-sprayed body in an inert atmosphere to form a dense, low-porosity beryllium structure of the desired thin-wall configuration.  The addition of the silicon and the exposure of the plasma-sprayed body to the moist atmosphere greatly facilitate the preparation of the beryllium structure while minimizing the heretofore dele-terious problems due to grain growth and grain orientation.
