  • Publication number: 20110090271
    Abstract: In order to stabilize a performance of a pump employed for processing in an inkjet printing apparatus such as sucking ink from a printing head with a low cost configuration and without the need of using any specific detecting unit, the following configuration is employed. Namely, a tube pump having a member with a curved surface aligned with a flexible tube for supporting the tube and a roller which moves while pressing (squeezing) the flexible tube is driven with a DC motor. To keep revolutions always constant, a current PWM control is employed for changing a power applied to the motor according to load fluctuations, and a phase of the roller is determined based on the current PWM value to manage a pressure generated by the pump and a discharge rate.

  • Patent number: 7926905
    Abstract: Even in the case where preliminary ejection is performed by a recording head having an array of pigment ink ejection outlets and an array of dye ink ejection outlets in which a length of the pigment ink ejection outlet array is longer than a length of the dye ink ejection outlet array, deposition of preliminarily ejected pigment ink at a preliminary ejection receiving portion is effectively prevented by providing an inclined surface at the preliminary ejection receiving portion so that ink from the dye ink ejection outlets is received at an upstream position of the inclined surface and ink from the pigment ink ejection outlets is received at a downstream position of the inclined surface in a direction of gravity.

  • Patent number: 7926895
    Abstract: This invention relates to a printing apparatus and a conveyance control method capable of allowing even an arrangement having a plurality of conveyance rollers in a printing medium conveyance path to accurately control conveyance of a printing medium. A pattern having a predetermined uniform density is printed on a printing medium a plurality of number of times by using a printhead while conveying the printing medium and changing the conveyance amount by a small amount. A conveyance correction amount obtained on the basis of the conveyance amount upon printing a pattern selected from a plurality of printed pattern is stored in a storage medium. Conveyance of the printing medium is controlled while correcting the conveyance amount of the printing medium by the conveyance means on the basis of the conveyance correction amount stored in the storage means.

  • Patent number: 7925377
    Abstract: Embodiments generally provide an apparatus and method for processing substrates using a multi-chamber processing system (e.g., a cluster tool) that has an increased system throughput, increased system reliability, substrates processed in the cluster tool have a more repeatable wafer history, and also the cluster tool has a smaller system footprint. In one embodiment of the cluster tool, grouping substrates together, and transferring and processing the substrates in groups of two or more, improves system throughput, and reduces the number of moves a robot has to make to transfer a batch of substrates between the processing chambers, thus reducing wear on the robot and increasing system reliability. Embodiments also provide for a method and apparatus that are used to increase the reliability of the substrate transfer process to reduce system down time.

  • Publication number: 20110063383
    Abstract: A fail-safe capability is realized that not only forestalls the execution by the user of the head replacement operation in an erroneous sequence while the printing apparatus is in operation but also prevents the splashing of ink even if the user attempts to inadvertently replace the print head. For this purpose, the ink supply and the opening and closing of the print head replacement cover are performed by a predetermined rotation of one drive source.

  • Publication number: 20110012109
    Abstract: A method of depositing a high quality low defect single crystalline Group III-Nitride film. A patterned substrate having a plurality of features with inclined sidewalls separated by spaces is provided. A Group III-Nitride film is deposited by a hydride vapor phase epitaxy (HVPE) process over the patterned substrate. The HVPE deposition process forms a Group III-Nitride film having a first crystal orientation in the spaces between features and a second different crystal orientation on the inclined sidewalls. The first crystal orientation in the spaces subsequently overgrows the second crystal orientation on the sidewalls and in the process turns over and terminates treading dislocations formed in the first crystal orientation.

The buffer layer, which may be a transition layer, may incorporate more than one group III metal, and may be deposited with amorphous or crystalline morphology. An amorphous layer may be partially or fully recrystallized by thermal treatment. Instead of a layer, a plurality of discrete nucleation sites may be formed, whose size, density, and distribution may be controlled.
