Abstract: An input buffer circuit having a latching function controlled by a transition detection circuit is disclosed. The input stage of the input buffer is connected to a delay stage, and to a transition detection circuit. The output of the delay stage is connected to a pass gate, which is controlled by the output of the transition detection circuit; a latch is connected to the other side of the pass gate. The transition detection circuit produces a pulse responsive to a transition, and the pass gate is turned off during the length of the pulse, with the latch maintaining and presenting the state of the input prior to the transition. After the pulse is complete, the new value of the input signal is latched and presented to the circuit. Since the pass gate is turned off during the transition detection pulse, a short and spurious transition at the input terminal is isolated from the latch by the pass gate (with the transition detection pulse lengthened), and does not appear at the output of the input buffer circuit.

Abstract: Polycarbonate is prepared according to the invention by the two-phase interface process, in which, in a first reaction step, gaseous phosgene is combined continuously with from 25 to 30% strength sodium bisphenolate solution, initially without an excess of sodium hydroxide solution, using a special mixing system in a tubular reactor without dissipation of heat of reaction. The aqueous solution is prewarmed to at least 45 DEG C. After a residence time of at least 10 seconds, optionally still in the tubular reactor, sodium hydroxide solution is metered in. In the second reaction step, the heat of reaction in a stirred reactor is dissipated and the polymer chain is built up with addition of triethylamine. These measures are optionally supplemented by splitting the bisphenolate metering in the tubular reactor. Suitable organic solvents are methylene chloride and chlorobenzene. The process according to the invention gives a high yield of phosgene.

Abstract: This multiprocessor circuit has interruption restriction circuits (21-24) connected between the interruption line (1) for inputting interruption signals and each of CPUs (11-14) connected in parallel with the interruption line (1) to restrict the input of interruption signals to each CPU under certain conditions. This interruption restriction circuit (21-24) counts the number of interruption signals received by each CPU during a specified period set at the timer using a counter means (32). When the count for a CPU exceeds the predetermined value, the multiprocessor circuit causes the input disabling means (33,34,40) to disable the input of interruption signals to that CPU for a certain period of time and thereby distributes the interruption signals to a plurality of CPUs almost equally.

Abstract: A torque-restraint mounting system for connecting an aircraft engine (30) to a structure (36) including at least two hydraulic mountings and at least one other resilient mounting (34). At least two of the hydraulic mountings (38,40) are fluidicly interconnected via a fluid filled conduit. This allows for the torque to be reacted between the aircraft engine and the structure by placing the fluid in compression. The relative torque-induced displacement occurring between the aircraft engine and the structure for any specific operating condition is counteracted by tuning the amount or volume of fluid within the torque-restraint system, or by tuning the coefficient of thermal expansion of the fluid. Thus, as the torque-restraint mounting system heats up, the aircraft engine will change rotational position such that its room temperature untorqued orientation can be maintained. This can have significant benefits in terms of increasing service life of the engine mounting system.

Abstract: A sharps collector (10) comprising a container for holding, storing, and disposing syringes. The sharps collector includes a disposable receptacle (12) and a decorative cover (14). The receptacle preferably has two elongate apertures (40) and chutes (54) associated wit each aperture (40) and chutes (54) associated with each aperture (40). The chutes (54) are designed to guide syringes into the receptacle (12) once the syringes pass through an aperture (40). The chutes (54) also obstruct syringes which are already contained in the receptacle (12) from protruding or re-emerging out of the receptacle (12). The decorative cover (14) is reusable and fits over and attaches to the receptacle (12). When the cover (14) is attached to the receptacle (12), it conceals the apertures (40) and chutes (54) of the receptacle (12). The cover (14) includes an elongate aperture through which a shuttle is accessed. The shuttle (16) directs syringes to the concealed apertures (40) and chutes (54) of the receptacle (12). The syringes to be disposed are placed in the shuttle (16) and the shuttle (12) is manually shifted such that a syringe is pushed towards an aperture (40) and chute (54). The syringe then falls through the aperture (40), is guided by the chute (54), and ultimately falls into the receptacle (12) and is contained within the collector (10). The cover (14) can be detached from a receptacle (12) when that receptacle (12) is ready to be discarded.

Abstract: The light beam in an obstruction detector is coded into packets of pulses by a transmitter. When the light beam is received, the receiver recovers the code signal and supplies it to a code detection circuit. To detect the code, the circuit supplies the code signal and a delayed version of the code signal to an "exclusive or" gate. If the code is present, the gate produces a pulsed output resulting in a "safe" signal being sent to a door opener control circuit. If no code is present, the gate produces a relatively constant output resulting in an "unsafe" signal being sent to the door opener circuit. The "unsafe" signal is produced not only in response to obstructions, but also, in response to errors and malfunctions in the wiring to the transmitter and receiver and in the transmitter and receiver themselves.

Abstract: A method and system of communicating between moving participants such that each participant is provided with a first time slice and a respective priority listing containing the name of each participant once only, each participant thus having the top priority for one first time slice only. Also allocated to each participant is a second time slice during which he must transmit his identity as well as the identities of all his near neighbors within a radius( R ) thereof. For each participant ( A ) there is stored the identity of all near neighbors ( B ( A ))and all far neighbors ( C ( A )) being within a radius( R )of his near neighbors( B ( A ))and who are not also near neighbors ( B ( A ))of (A). During each first time slice, any participant having a higher priority for the respective first time slice than all of his near and far neighbors may transmit data including the identities of at least those of his near neighbors who became near neighbors since his previous transmission. During each second time slice, non-transmitting participants update their respective list of near neighbors in respect of a transmitting participant according to whether his transmission is, or is not, received by them.

Abstract: Improved catalyst-downcomer-tray assemblies for vapor liquid contact towers. Downcomers are constructed for receipt of bundles of catalyst media used to promote chemical reactions therein. Raised, perforated regions of the underlying trays are then disposed therebeneath for improving mass transfer efficiency. The raised regions reduce fluid pressure to vent excess vapor from downcomers and trays therebeneath. The vapor generated within the downcomers from the catalytic reaction may then be selectively directed into the liquid discharged from the downcomer disposed on the tray above and imparted with a horizontal flow characteristic. In this manner the catalytic reaction vapors can be effectively released to facilitate a stabilized vapor-liquid flow configuration with improved chemical reaction occurring in the downcomer of the process tower.

Abstract: Automatic print rate-controlling and pen-servicing method and apparatus are described for power management and for determining appropriate servicing intervals for plural-pen ink-jet printers. The preferred method involves counting the number of drops (12) of ink that are fired from each of plural pens in the printer's printhead carriage (14) and optionally calculating (20) the pen firing rate such that printer throughput can be controlled to limit time-averaged power and such that pen servicing frequency can be based upon the need for such servicing. The counts are maintained in memory connected, for example, with the printer's microcontroller (20), as are parameters that the microcontroller (20) uses to determine appropriate drop count-based print rate controlling or pen servicing that reduce printer throughput only to the extent necessary. The preferred apparatus includes a drop counter (12), a service station (16) for wiping and spitting plural pens within a printhead carriage (14) and a controller (18) responsive to the drop counter (12) to control the printing rate and to move the printhead carriage (14) into operative association with the service station (16) based upon drop count, firing rate, time-averaged power capability, printhead location and other predetermined criteria.

Abstract: A time-division multiplex switch (100) switches a hierarchy of data rates. It sets up higher-rate connections not as a plurality of individual lowest-rate connections but as one or more time slots in each one of a plurality of sequential frames (40, 50) that correspond to that higher rate in each superframe (30). A time-slot- interchange switching element (131, 141) of the switch utilizes a plurality of physically or logically distinct double-buffered data memories (301,302, 303) each corresponding to a different one of the superframe and different-size ones of the frames. Reading and writing of each of the data memories' buffers alternates with the corresponding one of the superframe and different-size frames ; reading of a data memory's buffer immediately follows writing of that buffer. Information from all incoming time slots is written into each one of the data memories, but only information corresponding to the data rate of an individual data memory's corresponding frame size is read from that data memory into outgoing time slots. A control memory (305) maps memory locations of the data memories to output time slots. A corresponding control architecture in a switching element (1700) of a time-multiplexed switch (120) uses a control memory (1701) that maps input ports to time slots of an output port.

Abstract: It provides a process to form on a certain conductive type semiconductor substrate 1 insulation layer 9 having openings 11, which regions will become source and drain; a process to form diffusion layer 8 of the same conductive type as semiconductor substrate 1 in to-be-drain space, with insulation layer 9 and photoresist 10 as masks; a process to form side wall layer 13 alongside openings of insulation layer 9; a process to form diffusion layers 4 and 5, conductive type of which layers is opposite to that of semiconductor substrate 1, in to-be-source and to-be-drain regions, with insulation layer 9 and side wall layer 13 as masks; a process to remove insulation layer 9 and side wall layer 13; and a process to form insulation layer 2 on semiconductor substrate in channel region distinguished by, and including part of, diffusion layers 4 and 5, and to form floating-gate electrode 3 on insulation layer 2, and control-gate electrode 7 on floating-gate electrode 3 with insulation layer 6 in between. The manufacturing method according to this invention forms drain and high density P-type diffusion layer by making use of side wall layer.

Abstract: A method and system for dynamically generating object connections is provided. In a preferred embodiment, a connection can be generated between a source object and a sink object using a connection point object. A source object has connection point objects where each connection point object corresponds to a particular interface. A sink object implements one or more notification interfaces for connecting to a source object. A connection point object of a source object can connect to multiple notification interfaces, which belong to one or more sink objects. A connection point object keeps track of pointers to the notification interfaces to which it has been connected. In order to generate a connection, a sink object requests from a source object a connection point object corresponding to a particular interface. The source object determines whether it supports such a connection point object, and if so returns a pointer to the connection point interface of the determined connection point object. The sink object then requests to be connected to the connection point object using the returned connection point interface pointer and passes a reference to a notification interface of the sink object corresponding to the particular interface. The connection point object then stores the reference to the notification interface of the sink object, creating a connection between the sink object and the source object. At some later time, the source object can utilize the connection to notify the sink object through the connected notification interfaces.
