  • Patent number: 6802567
    Abstract: The invention is a chair having a removable surface (a “skin”), attachments, and a frame with a pair of opposing side members with channels to accept the attachments. The skin comprises cords incorporated into a material that has sufficient resiliency to bear the load of the chair user. The attachments have at least one portion, whereby a portion of the attachments connects to the cords of the skin and a portion of the attachments connects to a side member. The opposing side members have a hollow or grooved channel to accept a portion of the attachment used to connect the attachment to the side member. The skin attaches to the frame through the use of the attachments by, for each side of the skin, sliding the portion of the attachments used to connect the attachment to the side member into the channel of the side member. Replacement of the skin is relatively easy and can be accomplished by unskilled persons by sliding the attachments out of the opposing side members.

  • Patent number: 6802570
    Abstract: A boat trailer roller wheel mounting system for carrying an insignia in a predetermined orientation is provided. Included is a closed-ended wheel bushing which carries indexing for mating with an indexed wheel support arm in a predetermined, rotational orientation. The roller wheel turns on and is held by the indexed bushing. A quick release retainer ring fixes the bushing to the support arm and acts as an inboard longitudinal movement stop for the wheel. The bushing indexing on the support arm transfers the rotational thrust created on bushing, due to the rotation of the wheel under a load, directly to the support arm and therefore eliminates this rotational thrust from acting upon the retainer ring. An end cap is formed at the closed outer end of the bushing and has an annular projection surface extending beyond the bushing surface to provide a longitudinal thrust surface against which the wheel hub can operate.

  • Patent number: 6802571
    Abstract: A brake release unit is provided between a transmission control unit for controlling a transmission and a clutch device. Pressure oil supplied from a hydraulic pressure source to the clutch device is also guided to an accumulator of the brake release unit. When the engine is stopped, pressure oil from the clutch device is collected in a reservoir, and the transmission operates as a parking brake. Pressure oil accumulated in the accumulator is kept as it is. If a solenoid switching valve of the brake release unit is driven as a result of operation of a switch in the operator's cabin, pressure oil accumulated in the accumulator is supplied to the clutch device. As a result, it is possible to easily release the parking brake.

  • Patent number: 6802573
    Abstract: A parking brake control circuit engages the parking brake of a vehicle when the transmission of the vehicle is in the “park” position and the engine of the vehicle is turned off, without requiring the constant application of electrical power. The parking brake control circuit utilizes latching solenoid technology that eliminates the need for a constant voltage source. A time-delay relay is used to change the state of the latching solenoid. The time-delay relay is preferably activated through a circuit containing an engine oil pressure switch, a transmission park switch and a vehicle speed switch. Activation of the relay latches the solenoid in a position that allows the parking brake to be applied, without requiring the application of a constant voltage to the solenoid. Accordingly, the possibility of inadvertent brake application due to electrical failure is avoided.

    Abstract: The liquid-jetting apparatus has a liquid-jetting head with nozzle openings through which liquid particles are jetted. The liquid-jetting head performs a flushing operation to remove the thickened liquid from the nozzle openings to recover its normal liquid-jetting ability. The flushing operation jets liquid particles having a weight of 10 ng or below successively through the nozzle openings at a jetting speed of 8 m/s or above. The liquid-jetting apparatus is capable of achieving a satisfactory flushing operation to ensure a satisfactory liquid-jetting characteristic by recovering from a thickened state in a liquid in the nozzle openings even if the liquid is un-uniformly thickened in the nozzle openings.

  • Patent number: 6802593
    Abstract: The present invention provides a method and device for the acoustic ejection of fluid droplets from each of a plurality of fluid-containing reservoirs. The droplets are ejected toward sites on a substrate surface for deposition thereon. The device is comprised of: a plurality of reservoirs each adapted to contain a fluid; an ejector comprising a means for generating acoustic radiation and a means for focusing the generated acoustic radiation so as to eject fluid droplets from the reservoir fluids; and a means for positioning the ejector in acoustically coupled relationship to each of the reservoirs. The invention is useful in a number of contexts, particularly in the preparation of biomolecular arrays.

  • Patent number: 6802594
    Abstract: In a printing system, printhead modules with fiducials are used to misalign mounting of the modules to a support beam by a distance calculated from: the difference in coefficient of thermal expansion between the support beam and the modules; the spacing of the modules along the beam; and the difference between production temperature and operating temperature. The beam is composed of a silicon core, an outer metal shell and an elastomeric layer therebetween. The system ensures alignment of the modules at the operating temperature.

  • Patent number: 6802595
    Abstract: A flexible-film wire substrate is bent at first, second and third bent portions. Wires of a flexible wire pattern are deflected at least between the second bent portion and the third bent portion so that a pitch increases from the second bent portion toward the third bent portion. By bending the first, second and third bent portions so that the wires are substantially orthogonal to each bending line, the flexible-film wire substrate can be excellently bent without influencing the flexible wire pattern on the flexible-film wire substrate.

  • Patent number: 6802599
    Abstract: A droplet generator for a continuous stream ink jet print head includes an elongate cavity for containing the ink and nozzle orifices in a wall of the cavity for passing ink from the cavity to form jets. The nozzle orifices extend along the length of the cavity. An actuator is disposed on the opposite side of the cavity to the wall for vibrating the ink in the cavity such that each jet breaks up into ink droplets. In operation of the generator, a standing wave is present in the ink in the cavity. The cross-sectional area of the cavity varies along its length in a manner so as to tailor the form of the standing wave in the cavity such that each jet breaks up into the ink droplets at a respective predetermined distance from the wall of the cavity.
