Abstract: A capacitor suitable for use with a DRAM memory cell is composed of multiple layers of polycrystalline silicon. The storage node is formed from a polycrystalline silicon layer sandwiched between two polysilicon ground plate layers. First the bottom polycrystalline silicon plate layer (26)is fabricated, followed by an isolation step and fabrication of the storage node polycrystalline silicon layer(30,50). Following another isolation step, the polycrystalline silicon top plate layer(62)is then formed and connected to the bottom plate layer. The storage electrode employs a buffer polysilicon layer (30) and contacts the active region via an etched hole using sidespacer insulation(48). Sidespacers (60) are also used to isolate the outer edges of the storage electrode.

Abstract: A plasma etching process is provided which etches n-­type, p-type, and intrinsic polysilicon on the same wafer at substantially the same rate. Native oxide is first re­moved by etching in a conventional oxide etchant, such as SiCl₄/Cl₂, BCl₃/Cl₂, CCl₄, other mixtures of fluorinated or chlorinated gases, and mixtures of Freon-based gases. The polysilicon is then etched in an etchant comprising at least about 75% hydrogen and the balance a halogen-contain­ing fluid, such as chlorine. The silicon etchant etches at a rate of about 300 to 500 Å for a batch of 10 wafers, de­pending on hydrogen concentration, power, flow rate of gas mixture, and gas pressure.

Abstract: The storage tanks found in oil terminals for retaining, in the form of a liquid phase (20) below a vapour phase (30), large quantities of product with a vapour pressure greater than 50 kilopascals at the storage temperature present a problem during filling when high injection flow rates of the product must be guaranteed. In order to overcome this problem economically and flexibly, the present invention proposes, while the product is injected into the storage tank (6) in liquid form, evacuating the vapour from the vapour phase (30) of this storage tank (6), condensing it and returning it to the storage tank (6) by means of an ejector-condenser (10) in which at least a portion of the injected liquid product flows. <IMAGE>

Title: Improved radionuclide generator system and method for its preparation and use.
Inventor: VANDERHEYDEN JEAN-LUC E
IPC: A61K51/12
Filed: 1990-08-31
Abstract: Improved radionuclide generators include a substantially insoluble salt of a parent radionuclide precursor which may be directly irradiated and then packed in a column for subsequent elution of the daughter radionuclide without the production of counter ion isotopic contaminants. The parent radionuclide precursor is provided in the form of an insoluble salt of the parent element whose counter ion, preferably aluminum, forms a relatively soluble salt with the desired daughter radionuclide. The improved generators may be prepared by reacting a parent radionuclide precursor with aluminum to obtain an aluminum salt of the precursor having low solubility in water, irradiating the aluminum salt to obtain an irradiated aluminum salt of the parent radionuclide, and then disposing the irradiated parent radionuclide in an elutable container. Useful parent radionuclide precursors include molybdenum-98 in the form of molybdate for the production of daughter 99mTc, as soluble pertechnetate, and tungsten-186 in the form of tungstate for the production of daughter 188Re as soluble perrhenate. The daughter 99mTc or 188Re may be eluting the generator matrix, e.g., with a saline solution.

Abstract: The cryptographic system is comprised of two stations A and B in which a respective string S A  and S B  of digits is stored. In station A an error-control information string C is generated from string S A  and transmitted to station B over an error-free public channel CH1. In station B a particular string D and a decision bit F are generated. String D maximizes a predetermined reliability function of a string combination (S B ,C,D). Decision bit F is assigned the value 1 if and only if a maximum value taken on by the reliability function is greater than a predetermined threshold. Decision bit F is transmitted to station A over an error-free public channel CH2. In both stations A and B, the respective strings S A  and S B  are tagged as accepted when said decision bit F has the value 1. The above sequence is repeated, resulting in a plurality of tagged strings which are concatenated at stations A and B to result in a random cipher key shared by the stations A and B. 
     The predetermined reliability function can be defined as a conditional probability P-(S A  = D| B  = S B ,= = C) that a random variable S A  corresponding to string S A  is equal to string D, given the conditions that a random variable  B  corresponding to string S B  is equal to that latter string S B  and a random variable C corresponding to the error-control information string C is equal to that latter string C.

Abstract: 2.1 A known radiotelephone network has fixed radio stations (10, 11) with spatially limited coverage zones (12, 13) at a distance from one another. Mobile radio stations (24) which are located outside the coverage areas (12, 13) cannot establish a radio connection with a fixed radio station (11). It is therefore desirable to provide these mobile radio stations also with the facility of a radio connection with a fixed radio station. 2.2 For this purpose, fixed radio stations (20, 30) are set up outside the coverage areas (12, 13). Each radio station has two antennas (21, 22). One antenna (21) is directed towards a fixed radio station (11) with favourable reception characteristics and the other antenna (22) is directed towards a mobile radio station (24) located at the radio station. 3. The drawing shows a block diagram of a radio telephone network according to the invention. <IMAGE>

Abstract: The push-pull amplifier (1) has two inputs (5,6) with 180  phase difference between them. With no signal at the inputs a small idling current is established in the current mirrors (Tr7, Tr11, Tr9, Tr12) to eliminate crossover distortion. With a positive signal at input 6 [and thus a negative signal at input (5)] the current mirror transistor (Tr9) becomes OFF and Tr12 acts as a normal amplifier for the signal from Tr3. For reverse input signals the operation reverses.

Abstract: A system for maintaining a predetermined tension of a wire (22) has a rotatable wire supply spool (24), a motor-driven wire take-up spool (12), a motor- drive wire feed spool (26). the wire (22) is wound around the supply spool (24) and is also attached to the take-up spool (12). The wire (22) also passes partially around the feed spool (26) and a pulley (32) or guide which is attached to a pivot arm (34). The pivot arm (34) is positioned between the take-up spool and the supply spool. A frictional layer is disposed around the outer circumferential surface of the feed spool (26), to prevent the wire from sliding across the frictional layer of the feed spool. 
     The elongated pivot arm (34) has its free end (32) positioned agains the wire. The pivot arm (34) pivots in response to the differences in speed between the supply and take-up spools (24,12). A motion sensor (40,62,64) detects motion of the pivot arm and generates a control signal in response. The control signal is electrically conducted to a stepper motor (74). The stepper motor is electrically connected in turn to the feed spool to establish the speed of rotation of the feed spool and thereby match the supply spool speed with the take-up spool speed. The pivot arm can be weighted and oriented at an angle different from its rest position angle to establish the desired tension on the wire.
