Abstract: Semiconductor devices are described which are made by a process involving the use of certain types of glass layers. These glass layers have high silica content, small amounts of boron oxide and optionally small amounts of aluminum oxide. The glass layers are put down by e-beam deposition procedure using a glass target made from restructured glass. Commercial availability of such glass makes the procedure very convenient. Such glass layers are advantageously used as barrier layers in annealing procedures used when semiconductors are doped (e.g., ion implantation in semiconductors) and as encapsulating layers in finished devices.

Abstract: An arrangement and method for compiling telecommunication traffic analysis data includes the steps of collecting call data for a plurality of calls to a single customer from a signaling circuit that commonly carries the signaling for calls to a plurality of customers. The call data is transmitted to and stored in a call data processor which processes the call data to compile a summary of traffic data for the plurality of calls to the customer. Further processing of the summary of traffic data results in a change of a parameter in the customer's call processing logic and a reduction of call blocking for subsequent calls.

Abstract: An article for the sustained release of an insecticide into the ambient air comprises an elastomeric matrix, with the insecticide dissolved in the matrix. The matrix material has a modulus between about 10.sup.4 Pa and about 10.sup.8 Pa at 23.degree. C., and a glass transition temperature less than 0.degree. C. The matrix comprises polyurethane formed by reacting hydroxyl-terminated polybutadiene or polyisoprene and 4,4' diphenylmethane diisocyanate, and the insecticide is 2,2' dichlorovinyl dimethyl phosphate. The insecticide-containing matrix is contained in a plastic bottle, and typically protected against inadvertent skin contact by means of a dermal barrier. The article also comprises means for activating the article such that, prior to activation, release of insecticide into the ambient air is prevented, whereas such release can take place after activation. Exemplary activation means comprise a metal foil seal of the plastic bottle. The article is effective in controlling insect infestation (e.g.

Abstract: A nonaqueous, lithium cell is described which exhibits excellent safety characteristics when exposed to abusive testing, as well as high energy density, good charge and discharge rates, and long recycle life. Particularly unique is the composition of the electrolyte which contains such substances as ethylene carbonate, propylene carbonate and one or more polyethylene glycol dialkyl ethers.

Abstract: Methods and arrangements for properly associating an alerting message from an ISDN user terminal with the control process associated with the message are disclosed. Each call, in a disclosed switching network, is associated with a call control process and data structure. When an external request for a call is received, a data structure including a predetermined broadcast Terminal Endpoint Identifier (TEI) and a call reference value selected by the network, is created. Further, a message including the broadcast TEI and the selected call reference value is sent to a user terminal. The user terminal responds with an alerting message including the selected call reference value and a TEI unique to that terminal (not the broadcast TEI). The switching network searches the data structures until a data structure is located which includes the call reference value of the received message and the broadcast TEI.

Abstract: Photosensitive bodies that are sensitive to ultraviolet radiation and that exhibit excellent contrast are formed from base soluble polymers such as poly(methyl methacrylate-co-methacrylic acid) physically mixed with base insoluble materials such as o,o'-dinitrobenzyl esters. The base insoluble esters decompose upon irradiation to form base soluble entities in the irradiated regions. These irradiated portions are then soluble in basic solutions that are used to develop the desired image.

Abstract: Crystals of potassium titanyl phosphate suitable for device applications are grown by a hydrothermal process. By maintaining the growth temperature substantially below conventional levels, the crystal growth rate is maintained, and noble metal-lined vessels are employable.

Abstract: A low temperature procedure for depositing III-V semiconductor materials that offers the possibility of higher deposition rates together with abrupt junction formation has been found. This process involves the irradiation at a deposition substrate with a high power density radiation source of deposition gases such as organometallic materials, e.g., trimethyl gallium and trimethyl indium. By utilizing a sufficiently high power density, multiphoton processes are induced in the deposition gas that, in turn, lead to advantageous deposited materials.

Abstract: Supported intermetallic compounds are produced by a two-step process. In the first step, a supported metal is formed, for example, by solvating a metallic salt such as nickel nitrate and applying it to a support medium. The treated support body is then heated in the presence of a reducing agent to produce elemental metal. The supported metal is then treated with a reactive organometallic or metal hydride compound to yield a supported intermetallic compound. For example, supported elemental nickel is treated with hexamethyldisilane to produce supported nickel silicide.

Abstract: An integrated circuit chip with a preferred ground structure and including only pull-down transistors (on-chip) is operated by means of an off-chip pull-up transistor arrangement for precharging the data bus to logic high. The arrangement exhibits relatively low noise characteristics allowing relatively high frequency operation without generating noise voltages which exceed FET threshold voltages.

Abstract: Disclosed is a high resolution optical scanning method and apparatus. Light from a source, such as a laser, is focused onto a flat, rotating mirror. The reflected light is made incident upon a stationary elliptical mirror such that the real or virtual source is at one focus of the ellipse and the points on the line to be scanned are at the other focus along the lateral dimension of the mirror. A large useful angle of rotation is thereby achieved for each line scan.

Abstract: An arrangement comprising a host switching system and a number of remote switching modules which are selectively interconnected by a time-multiplexed switch such that voice and data traffic as well as control information is conveyed between modules without being routed through the host system network. The arrangement allows the integrated stand-alone operation of the remote switching modules and advantageously reduces traffic through the host system during normal operation.

Abstract: Two input stages (10,12) are interconnected so that their input common mode voltage ranges to one side of signal ground are combined to provide a common mode voltage range substantially equal to the supply voltage. One stage has N-channel differential input transistors (N1,N2), while the other stage has P-channel differential input transistors (P3,P4). The input current branches of the stages are interconnected by current mirror transistors (N6,N7) so that signal current is shared. The output (22) is taken from one branch of the N-type stage (10) and coupled to an output stage (24) with frequency compensation (C,R).

Abstract: A large scale sequential integrated circuit is made amenable to scan design testing by the inclusion of special multiplexing and storage circuits which respond to a pair of test control pulses to reconfigure the circuit to include one or more shift registers and to step the scan test data through the shift registers. In particular, the pair of test control pulses are applied to the two terminals to which, in normal operation, are applied the clock pulses which are used to control the storage elements and which, in such operation, are never both simultaneously high. To initiate the scan test operation, these test control pulses are made simultaneously high and the circuitry responds to such conditions.

Abstract: The pyrolysis of aromatic compounds with fused rings in the aromatic system which form free radicals on the peri position, for example, by eliminating a stable inorganic gas produces desirable products. These products include electrically conductive inert films. Further, with the addition of suitable inorganic compounds to the reactant, superconducting materials are obtainable. The addition of sulfur to the pyrolysis reactant also is possible and allows production of compounds useful as donors for the production of organic electrically conducting compositions.
