Abstract: ABSTRACT           An electromagnetic actuator comprising a housing of magnetizable material defining a stationary pole, a bobbin supported by the housing and having an interior bore, an armature comprising a permanent magnet provided with a pair of magnetic poles and movably supported by the bobbin, a pair of coils circumposing the armature and having wire end portions and means securing the wire end portions to the bobbin.  The bobbin comprises a pair of bobbin sections and means connecting the bobbin sections,  each bobbin section having an inner and an outer rim and supporting one of the coils between the rims.  A collar section integrally connects each of the bobbin sections and comprises a keeper for securing the wire end portions and a radially extending vent bore.  The collar section associates each bobbin section with coil with one of the magnetic poles, receives wire securement forces from the keeper and permits the wall thickness of each bobbin section to be minimized, thereby minimizing separation between the poles and maximizing magnetic flux constrained to pass between the poles.  Ener-gization of the coils exerts a force on the coils with respect to the armature resulting in linear motion of the armature.

Abstract: TCOM                         DATA COMMUNICATIONS TERMINAL            ABSTRACT OF THE DISCLOSURE A data communications terminal is provided for interfacing with a central data processing system to handle a variety of data acquisition and control functions including the minitoring and control of security devices and pay television receivers. The terminal includes a microcomputer unit for receiving and processing  data from the central processing system and from remote units which generate data signals in response to abnormal conditions. A data reception and transmission unit include a radio frequency modem for converting data to and from a frequency modulated format and a data converter for changing the serial bit data to parallel word data. An identification unit provides data to the microcomputer regarding the identifi-cation of the terminal which can be compared to the address portion of the incoming data from the central processing system. Data generating means are provided for generating and transmitting response data to the microcomputer for transmission to the central processing system. An address decode unit identifies and actuates the various element in this system. The remote data terminal functions in an "interrupt" mode with relation to the central data system so that it communicates with the central data system only when abnormal conditions are detected. Otherwise, the terminal handles its own internal monitoring and control functions. Transmission of data to and from the terminal is preferably along coaxial cable. When used in conjunction with a television receiver, the same coaxial cable may be used for the transmission of television signals to the receiver. In this mode, the terminal includes a television port unit which is activiated by the microcomputer to enable access by the receiver to the cable television network in response to appropriate authorization data from the microcomputer.

Abstract: FABRICATION OF MICROMIMINATURE DEVICES USING       PLASMA ETCHING OF SILICON AND      RESULTANT PRODUCTS          Abstract of the Disclosure This invention relates to fabrication of microminiature devices, such as integrated circuit utilizing the delination of fine-line patterns in such devices by dry etching processes.  By utilizing a fluorine-containing gaseous compound in a plasma etching process, isotropic etching of doped or undoped monocrystalline silicon and polycrystalline silicon is achieved.  The etching processes are substantially free of any proximity effects and are characterized by a high etching rate at relatively low power levels, high selectivity (with respect to, for example, silicon dioxide) and excellent uniformity.  By mixing other gases (for example, chlorine) with the fluorine-containing gas, the amount of undercutting achieved during the etching process can be selectively controlled.
