  • Patent number: 7232699
    Abstract: A Method of Making a High Precision Microelectromechanical Capacitor with Programmable Voltage Source includes steps for forming a monolithic MEMS device having a capacitance actuator, a trim capacitor, and a high precision, programmable voltage source. The trim capacitor has a variable capacitance value, preferably for making fine adjustments in capacitance. The capacitance actuator is preferably mechanically coupled to and electrically isolated from the trim capacitor and is used to control the capacitance value of the trim capacitor. The capacitance adjustment of the trim capacitor is non-destructive and may be repeated indefinitely. The trim capacitor may be adjusted by mechanically changing the distance between its electrodes. The programmable voltage source provides a highly accurate and stable output voltage potential corresponding to control signals for controlling the capacitance actuator.

  • Patent number: 6692100
    Abstract: Cleaning apparatus and method of assembly therefor for cleaning an inkjet print head. The cleaning apparatus comprises a web supply for supplying a cleaning web therefrom and a web receiver for receiving the web. A web drive drives the web from the web supply to the web receiver. The web drive pulls the web from the web supply with a first tension force and also pulls the web onto the web receiver with a second tension force greater than the first tension force, so that the web is wrinkle-free while the web slidably engages an exterior surface of the print head to clean the print head. The web remains wrinkle-free to ensure that the surface of the web will contact the surface of the print head without gaps in contact coverage. This enhances cleaning effectiveness compared to a cleaning web having wrinkles.

  • Patent number: 6636332
    Abstract: System for reproducing images and method thereof. An image acquisition device belonging to the system acquires the image and converts the image into indicia, which is defined by a digitally encoded compressed representation of the image in the form of one or more data image files. The image files are downloaded to a first printer which prints the indicia onto a first recording medium. The indicia printed on the first recording medium may overlay the image without interfering with enjoyment of the image because the indicia is printed in an invisible dye. In order to produce a quality reproduction of the original image, a sensor, which is disposed in sensing relationship to the indicia on the first recording medium, senses the indicia and generates a digital output signal in response to the indicia sensed thereby.

  • Patent number: 6607259
    Abstract: A thermal ink jet printer having enhanced heat removal capability and method of assembling the printer. The thermal inkjet printer includes a thermal inkjet print bead adapted to hold an ink body therein. A heating element is adapted to be in fluid communication with the ink body for generating heat to heat the ink body. A vapor bubble forms in the ink body to eject an ink drop when the heating element causes the ink body to reach a predetermined temperature. Presence of the vapor bubble forces on ink drop out the printer to form an image on a recording medium. A conductive heat removal structure is in thermal communication with the heating element and is also in fluid communication with the ink body. Heat generated by the heating element is transferred from the heating element and into the heat removal structure. The heat removal structure then surrenders the heat to the ink body, which functions as an “infinite” heat sink.

  • Patent number: 6521513
    Abstract: A method for singulating a semiconductor silicon wafer (10) comprising a plurality of semiconductor dice (20) arranged along a multiplicity of intersecting streets (30). Initially, a layer of photoresist (15)is patterned on the backside of the wafer (10). The semiconductor silicon wafer (10) is then etched using dry etching methods. As such, slots (22) are etched through the silicon of the wafer (10) aligned to the streets (30) forming a perforation. Simultaneously, tethers (40) are formed between the slots (22) interconnecting the adjacent dice (20) in order to maintain the wafer (10) mechanically intact. Furthermore, a membrane comprising integrated circuitry on the silicon wafer (10) is formed. The dice (20) of the wafer (10) are then separated for various purposes along the perforations. This is accomplished by applying pressure, such as manual pressure, to the wafer (10) so as to sever the tethers (40) which interconnect the dice (20) at their region (50) of reduced dimension.

  • Patent number: 6520629
    Abstract: An asymmetric heat-type inkjet printer includes an inkjet printhead having at least one nozzle for continuously ejecting a stream of ink that forms a train of ink droplets, a heater disposed adjacent to the nozzle for selectively thermally deflecting the droplet forming stream of ink either toward a printing medium, or an ink gutter that captures and recirculates the ink. To increase the angle of deflection that the intermittently operated heater imposes on the droplet-forming stream of ink, a steering fluid assembly is provided in communication with the inkjet nozzle for co-extruding a thin film of fluid around the ink which has a higher volatility and a lower thermal diffusivity than the liquid forming the ink. When the ink is water based, the steering fluid may be, for example, polyethylene oxide based surfactant, or isopropanol.
