Patent EP-0444407-A2 (EP)
Inventor: CHAPPELL BARBARA A
IPC: H03K19/20
Filed: 1991-01-18
Abstract: An AND gate includes first and second opposite-type field effect transistors (50, 56) , each including first and second conduction path terminals (52, 54; 58, 60) and a control electrode. The gate's output terminal (68) is connected, in common, to the second conduction path terminals (54, 60) of the transistors. A first logic input (ADR 1) is connected to the first conduction path terminal (52) of the first transistor (50) and a second logic input (ADR 2) is connected in common to the control electrode of the first transistor (50) and to the first conduction path terminal (58) of the second transistor (56). A third logic input (ADR 1N) is applied to the control electrode of the second transistor (56). In a standby state prior to the application of logic signals all three logic inputs are in the same state. This assures no conduction of logic signals, while conditioning the gate for rapid selection when logic signals are applied. Subsequently, logic signals are applied to the inputs with the third input being the complement level of the logic signal on the first input. As a result, the circuit's output terminal only provides a high state output if the first and second inputs are in the high state. An erroneous output is avoided in the event of a skew of the inputs due to a clamping action exerted on the gate's output by the first transistor. A logical decoding circuit using the above described AND circuit enables a one-out-of-32 decode to occur in three stages including a self-contained reset for fast cycle operation.

Abstract: A system provides convective transfer from a workpiece (10) to a flowing fluid. A gap (16) is formed between the workpiece (10) and a facesheet (12) containing fluid supply nozzles (18) and fluid return nozzles (20). The fluid is fed to the supply nozzles (18), travels a short distance within the gap (16) adjacent to the facesheet (12), and exits via return nozzles (20). The flow cross section and flow density facilitate heat transfer at a moderate flow rate and low fluid pressure. The system is also applicable for chemical transfer such as plating or etching printed circuit boards and for transfer through a semi-permeable membrane.

Abstract: A method of tuning a radio frequency coil for use in MR imaging applications uses reactive shunts having a reactance in parallel with a switch to connect sections of the coil to ground thereby constraining the resonant mode of the coil to a known orientation. A plurality of measurements of the frequency of the resonances along different such constrained orientations is used to deduce the frequencies of the two unconstrained orthogonal resonant modes of the coil and its orientation. The shunts may also be used to tune the coil according to the deduced frequencies of the unconstrained resonance and the desired frequency and orientation by adjusting the reactance of the shunts. A shunt having a variable reactance and a switch for shorting the RF coil as required uses a PIN diode in combination with a variable reactance.

Abstract: A transparent substrate of an optical memory is produced by injection molding using a stamper. Grooves and lands are alternately arranged on the optical memory, for tracking of light converged on the optical memory. The groove width is set in the range of 0.3 µm to 0.4 µm and the groove depth is set in the range of 80 nm to 100 nm. A decrease in the width of a land at each edge is restrained to 0.2 µm in maximum. With such dimensions, even when the track pitch is set to about 1.4 µm, it is possible to obtain a track crossing signal with intensity sufficient for performing an access operation to a target track. Moreover, since the dimensions bring about an improved reflectance at a land, the optical memory achieves an improved C/N and recording density.

Abstract: A mechanism prioritizes cross interrogate requests between multiple requestors in a multi-processor system where the delay due to cable length interconnecting requestors results in requests not being received within one machine cycle. Local and remote cross interrogate (XI) requests are latched up in storage control element (SCE) temporary registers before being prioritized. The local request is staged in a local delay register. The local request is selected from the local delay register by synchronization control logic, instead of the temporary register, when the remote request is issued one cycle earlier than the local request, or when both local and remote requests are issued at the same time, but the remote requests is from a master SCE. The staging of the local requests can be extended to multiple cycles, corresponding to the length of the cables between SCEs.

Abstract: A franking machine is disclosed in which the accounting memories are implemented by memory devices (15,16) in which each storage location comprises a volatile and a non-volatile cell. During normal operation data is written to the volatile cells of the storage locations and in the event of a power down the data is transferred from the volatile to non-volatile cells. The volatile cells preferably are semi-conductor and the non-volatile cells are ferreoectric capacitative devices which retain their polarisation without supply of power. The memory devices (15,16) may provide storage for accounting data and other data processed by a micro-controller (10) of the franking machine. In addition the memory device (15,16) may be utilised to store other data which is not to be processed by the micro-controller (10). Such data includes program data. In order to prevent such data being erased or over-written gating circuits (32) are provided to prevent write accesses by the micro-controller (10) to areas of memory utilised for storing data which is not to be changed.

Abstract: A neural network development utility assists a developer in generating one or more filters for data to be input to or output from a neural network. A filter is a device which translates data in accordance with a data transformation definition contained in a translate template. Source data for the neural network may be expressed in any arbitrary combination of symbolic or numeric fields in a data base. The developer selects those fields to be used from an interactive menu (602). The utility scans the selected field entries in the source data base to identify the logical type of each field (604), and creates a default translate template based on this scan (605). Numeric data is automatically scaled. The developer may use the default template, or edit it from an interactive editor (606). When editing the template (607), the developer may select from a menu of commonly used neural network data formats, and from a menu of commonly used primitive mathematical operations. The developer may interactively define additional filters to perform data transformations in series, thus achieving more complex mathematical operations on the data. Templates may be edited at any time during the development process. If a network does not appear to be giving satisfactory results, the developer may easily alter the template to present inputs in some other format.

Abstract: A laminar thermal imaging medium is prepared from a first element comprising a first sheet transparent to image-forming radiation and having at least a surface zone or layer of polymeric material heat-activatable upon subjection of the thermal imaging medium to brief and intense radiation, the first element carrying a layer of porous or particulate image-forming substance having cohesivity in excess of its adhesivity for the polymeric heat-activatable layer, and, on the opposed side of the layer of porous or particulate image-forming substance from the surface zone or layer, a first layer of adhesive, and a second element comprising a second sheet carrying a second layer of adhesive. One of the first and second layers of adhesive comprises a polymeric hardenable adhesive comprising a macromolecular organic binder having amino or substituted amino groups, and a photopolymerizable monomer. The first and second elements are laminated together with the first and second layers of adhesive in contact with one another, so forming a unitary laminar medium in which the hardenable adhesive remains in its unhardened condition and serves to reduce the tendency for the unitary laminar medium to delaminate on application of stresses to the medium. Only a short lag time, typically about 30 seconds, is required between lamination and curing of the hardenable adhesive in order to provide a strong bond between the two elements following curing.
