摘要:
The invention is directed to a keyboard where the keys are raised up from a retracted position upon the initialization of usage of the keyboard. An embedded airbag mechanism is self-inflatable to raise keys to the normal operating heights. The keys will be retracted when the airbag is deflated. The rising and retracting of the keys can also be controlled by hinge-like structure. The close and open of the cover of a laptop computer will activate the mechanism to raise and retract the keys on the keyboard.

A microwave applicator that provides a substantially uniform microwave field distribution over a large area, includes an elongated chamber, preferably operating in the length independent mode. A microwave source generates a microwave field at an output frequency. A waveguide or coaxial cable directs the microwave field from the microwave source into the elongated chamber, either through a side launch, end launch or multi launch. A frequency of the microwave field in the elongated chamber and the output frequency of the microwave source are matched through the use of controlled feedback of critical material and process parameters.
摘要:
A microwave applicator including a cylindrical elongated chamber used to process materials therein; a microwave power source capable of producing microwave power having an electric field; a waveguide connected to the chamber couples microwave power into the microwave chamber. The applicator provides microwave energy having a substantially uniform field distribution over a large area for processing materials such as a web or sheet-like product. The uniformity of the applicator is enhanced by the use of matching devices within the applicator to match the regions of the applicator with no load to regions where the load is present in a continuous manner.

The present invention related to an improved structure of an optically transparent element that can be used in optical scanners, supermarket scanners, lenses for eyeglasses, etc. The application of oxynitride PECVD films provide good hardness and optical transparency. Such films displaying these physical properties are extremely useful as a scratch resistant coatings in lenses and systems in which an article contacts a transparent surface, such as in scanners and in environments in which intermittent, environmental contact occurs such as in displays for computers and suchlike and in liquid crystal displays, touch displays and compact disks.

A control system for a blind microwave radiation tool a workpiece is described. The controlled system automatically tunes the cavity containing the workpiece. The control system automatically controls the temperature of the workpiece according to a predetermined temperature versus time schedule. Control system automatically determines when the workpiece has reached a particular predetermined physical condition. To achieve these results the control system automatically monitors applied power, reflected power or current temperature and automatically controls the microwave cavity volume and shape and launch structure including antennae location, cavity short location, cavity diameter, coupling loop position, etc. in order to maintain the cavity in resonance and to determine when to exit without operator intervention. Control system can run on a small computer or an embedded controller and is useful for automatically curing polyamic acid to polyimide to a predetermined percent cure, processing preimpregnated glass cloth in a continuous manner which can be used in circuit boards and drying and partial curing of web-like materials automatically without operator intervention.
摘要:
A microwave applicator includes an elongated chamber, preferably having a cylindrical shape, for processing materials therein. A waveguide, connected to the elongated chamber, couples microwave power into the elongated chamber. The cross-sectional area of the elongated chamber can be mechanically adjusted to control and maintain the microwave field uniformity and resonant mode, preferably the length independent mode TM.sub.010, during the processing of the material. The applicator can thus provide microwave energy having a substantially uniform field distribution over a large area for processing materials, for example, a web or sheet like product, plywood and pre-impregnated cloth, in a continuous manner.
摘要:
A continuous process for the fabrication of metal clad, laminated core structures, such as circuit board cores, wherein the copper layers on the laminate are used to form a waveguide which propagates microwave or RF radiation in TEM mode down the length of the structure for heating the core layers while the necessary pressure is applied. The TEM mode offers substantial advantages in the uniformity and control of processing in this environment. In particular, the system may be made tunable using the positioning or two pinch points, produced by rollers applying pressure to consolidate the layered material, which points create end chokes defining a heating and pressure region wherein the radiation is reflected. Alternatively, the metal layers may also be used as capacitor-like plates for applying RF energy across the layered material.
