摘要: Microwave diffuser films are describe that provide a modified microwave energy field on one side of the diffuser film and on the other side. The films include an insulative substrate having a first side upon which is deposited a metallic coating capable of selectively reflecting a portion of incoming microwave energy. A coating is formed in a plurality of discrete areas having a predetermined reflectivity. The shape and spacing of the areas may be varied so that energy emission from noncoated surfaces of the substrate is spatially distributed in one or more ways; i.e. the energy emission more uniform than the energy impinging on the coated surface, the energy emission is focused on one or more particular location and/or the energy emission is shielded. A food packaging system for microwave cooking, which includes the microwave diffuser film of this invention, is also described.

摘要: A conductive structure for use in microwave food packaging which adapts itself to heat food articles in a safer, more uniform manner is disclosed. The structure includes a conductive layer disposed on a non-conductive substrate. Provision in the structure's conductive layer of fuse links and base areas causes microwave induced currents to be channeled through the fuse links, resulting in a controlled heating. When over-exposed to microwave energy, fuses break more readily than the conductive base areas resulting in less absorption of microwave energy in the area of fuse breaks than in other regions where fuses do not break. In this way the fused microwave conductive structure compensates for the uneven microwave field within a microwave oven and at the same time provides a safer conductive structure less likely to overheat. In addition, by varying the dimensions of the fuse links and base areas it is possible to design and fabricate different fused microwave conductive structures having a wide range of heating characteristics. Thus, a fused microwave conductive structure permits food heating temperatures to be tuned for food type.

摘要: Security devices which are difficult to reproduce include a grid screen metallization pattern. The grid screen metallization pattern may be laid down over a hologram or diffraction grating formed as a surface relief pattern on a substrate, to form a visually identifiable, semi-transparent security device. Additionally, the metallization pattern may include resonant structures in which information about the security device is encoded. In some embodiments of these security devices, the metallization pattern is disposed in accurate registration with the underlying hologram or diffraction grating. These security devices are made by methods which include printing an oil pattern on the substrate. Areas on which oil is deposited do not receive metal during a metallization step. Since these methods do not use caustics, metallization patterns including features which would otherwise trap and hold caustics are possible.

摘要: A radial position sensor includes four capacitive electrodes oriented about a shaft, arranged in two diametrically opposite pairs. Sensor circuitry generates an output signal in proportion to the capacitance between the electrodes and the shaft; the capacitance between an electrode and the shaft increases as the shaft approaches the electrode and decreases as the shaft recedes from the electrode. The sensor circuitry applies an alternating voltage to one electrode of a pair and a 180 degree out of phase alternating voltage to the other electrode of the pair. The electrical responses of the two electrodes to their respective input signals are summed to form a radial deviation signal which is relatively free from the alternating voltage and accurately represents the position of the shaft relative to the electrodes of the pair.

摘要: A method and apparatus for supplying ink to an array of ink jets is provided by two fluidically independent reservoirs, each reservoir supplying ink to a respective end of a manifold which communicates with the array of ink jets via their inlet restrictors. During normal operations involving an acceleration of the array along a scanning path, the ink levels in the two reservoirs will remain the same since any difference in their levels will create a pressure differential that drives a flow of ink through the manifold from the higher level reservoir until such time that their levels equalize.

摘要: A three-phase inverter for small, high speed motors such as a miniature centrifical compressor which has a low voltage, high current requirement. The inverter is supplied with DC power at 28 volts, and produces power of about 50 to 500 watts at about 15 volts, and at frequencies of about 5 to 9 kilohertz. Six D-type flip-flops with clock inputs produce twelve signals which are provided to six bridge drivers. Each bridge driver controls two MOSFET's in series. The MOSFET's are supplied with DC power. Outputs are fed to primaries of adjacent transformers in a circular array. The transformer secondaries are arranged in a star configuration to produce stepped voltage and saw-tooth current output wave forms approximating sinusoids in three phases.
