  • Patent number: 6722738
    Abstract: A reclining device has leg portions formed in opposed end portions of each of slide pawls. Basically, a rotating cam bears the slide pawl at a middle bearing portion formed in a middle portion between the leg portions. Furthermore, the rotating cam bears the slide pawl also at the leg portions. Such a three-point supporting structure prevents the middle portion of a slide pawl body from deflecting radially inwardly even in the event of application of a turning force from an annular ratchet. Thus, the slide pawls are stably maintained in mesh with the ratchet.

  • Patent number: 6722745
    Abstract: The adaptive brake application and initial skid detection system allows rapid brake application and prevents deep initial skids. Brake torque is compared with a predetermined threshold brake torque. Wheel velocity error signals are also generated to indicated the difference between the wheel velocity and a reference velocity signal. A torque bias modulator integrator responsive to brake torque signals adjusts the wheel velocity error signals to provide an anti-skid control signal. The torque bias modulator integrator can also be initialized to the value of the measured brake torque when the wheel velocity error signals indicate the beginning of a skid. Brake torque difference signals are generated to indicate the difference between brake torque and a commanded brake torque, and an adjusted brake torque error signal is generated in response to the brake torque difference signals.

  • Patent number: 6722754
    Abstract: There is provided a method for monitoring paper or other jams of a carriage in a printer by monitoring the current waveshape in a first winding of a stepper motor at or near the time when a second winding of the stepper motor commutates. The current waveshape is received from a low-value sensing resistor, typically within an integrated circuit stepper motor driver device. Changes in the current waveshape during this time window may be interpreted and accurate deductions may be made concerning the loading of the stepper motor. In the case where the stepper motor is the drive motor for a printer carriage, the loading information may be used to detect a paper jam or similar problem in the printer carriage.

The capping member is displaceable into and out of abutment with the printhead for capping and uncapping the printhead respectively. A torsion bar arrangement acts on the capping member for displacing the capping member. A mechanical displaceable element co-operates with the torsion bar arrangement such that, when the element is in a parked position, the element engages the torsion bar arrangement to cause the capping member to be displaced into abutment with the printhead to cap the printhead. When the displaceable element is out of its parked position, the capping member is urged by the torsion bar arrangement out of abutment with the printhead.

  • Patent number: 6722759
    Abstract: An ink jet printhead includes a printhead substrate having a plurality of thin film layers and four side by side columnar arrays of drop generators formed in the printhead substrate and extending along a longitudinal extent. Each columnar array has drop generators that are separated by a drop generator pitch P. The drop generators produce ink drops having a drop volume that enables single pass printing of a resolution that is 1/(4P) dpi along a print axis parallel to the longitudinal extent. Four columnar arrays of FET drive circuits formed in the printhead substrate are employed to energize corresponding columnar arrays of drop generators.

  • Patent number: 6722760
    Abstract: A cliché of a gravure offset printing device is fabricated such that an organic layer and a photoresist layer are formed on a substrate. The photoresist layer is developed to form a photoresist pattern, and in a state that the organic layer is blocked with the photoresist pattern, the organic layer is etched to form a groove. The organic layer allows a fine process, so that a gravure offset printing device adopting the cliché can form a fine ink pattern. This fine pattern produces a resolution that is applicable to the production of semiconductors and liquid crystal display devices.

  • Patent number: 6722761
    Abstract: An inkjet recording device including a tank incorporated inside an inkjet recording head and divided into a large-capacity main chamber and first and second vertically-arranged needle-receiving chambers. Each needle-receiving chamber includes a connecting hole for communication with the main chamber and an opening for receiving a needle. First and second needles that pass through corresponding first and second resilient joints that seal the opening are inserted into the corresponding first and second needle-receiving chambers. The upper first needle is connected to a pump for discharging air through a first tube, and the lower second needle is connected to a main tank for supplying ink through a second tube. In each needle-receiving chamber, the connecting hole is positioned above the opening, and/or the connecting hole is made small. When the connecting hole is above the opening, the inkjet recording device reduces the tendency of ink to solidify near holes of the needles used to supply ink.

  • Patent number: 6722763
    Abstract: An inkjet pen and a pressure control device thereof. The inkjet pen comprises a body, a bag, a pressure plate, an abutting member, and a rib. The body includes a bubble generator. The bag is disposed inside the body, and communicates with the external environment so as to expand inside the body. The pressure plate, disposed inside the body and located adjacent to the bag so as to move inside the body, includes a first portion and a second portion. The first portion is located near the bubble generator. The abutting member is disposed in the body, and seals the bubble generator. The rib is disposed in the body and located near the second portion of the pressure plate. The second portion of the pressure plate is maintained at a predetermined position by the rib when the pressure plate is moved by the bag. Thus, the abutting member is properly moved by the first portion of the pressure plate when the pressure plate is moved by the bag.

    Abstract: An ink stick for use in a solid ink feed system of a phase change ink jet printer includes a three dimensional ink stick body that has a lateral center of gravity, a substantially horizontal perimeter, and opposed end surfaces. An ink stick guide element is formed in the bottom of the ink stick body, and the ink stick is adapted to travel through the feed channel along a feed channel guide rail. A portion of the ink stick perimeter forms a visually recognizable symbol, and a portion of the ink stick perimeter that is transverse to the feed direction of the channel has an insertion key element. Nesting elements are formed in the leading and trailing end surfaces of the ink stick body to nest with one another when ink sticks abut in the feed channel.

  • Patent number: 6722766
    Abstract: The self-cleaning eyeglasses are an invention that provides an efficient and convenient means for cleaning the surface of lenses without removing the eyeglasses from the face of the wearer. In order to accomplish this the present invention includes a novel design for a housing shaped to seat a watch battery and formed within the frame of the eyeglasses. Also introduced by the present invention is a dual motor design wherein each motor is housed in the frames of the eyeglasses above the lenses of the eyeglasses. The motors rotate a shaft over a fixed acute angle. Attached to the shafts of the motors are wiper arms held flush to the surface of the lenses. Also housed within the frames is an On\Off switch. When the switch is activated the watch battery will supply current to the motors which will drive the shaft to sweep the wiper arms over the lenses.

  • Patent number: 6722767
    Abstract: There is now provided a method for determining vision defects and for collecting data for correcting vision defects of the eye. The method comprises projecting an image into the eye of the patient with an adaptive optical system having adaptive optical elements. The optical characteristics of the optical elements can be individually changed by an electrical signal. The presence of distortions of the image as perceived by the patient is determined by interaction of the patient with the examiner. By way of an electronic control system the optical characteristics of the adaptive optical elements are changed through outputting of an electrical signal to obtain a modified image with minimized distortions in the eye of the patient. The optical characteristics of the adaptive optical elements, as modified, are determined and vision correcting data for the eye being examined are computed from the optical characteristics of the adaptive optical elements, as modified.
