20100156988 | LIQUID EJECTION HEAD AND PRINTING APPARATUS - A print head of which influence on an ink to be ejected from an ejection port subsequently by an air flow generated by an ink to be ejected from the ejection port is suppressed evenly for respective ejection ports in the print head is provided. A print head has an ejection port for ejecting ink. On an ejection port forming face formed with the ejection port, a projection projecting from the ejection port forming face is formed. The projection is arranged at a position where the distance from a center of the ejection port is within the maximum of a diameter of a vortex core of a vortex that is formed when liquid droplets are ejected in the case without a projection. | 06-24-2010 |
20100201746 | LIQUID EJECTION HEAD - A print head is provided by which a temperature change depending on each region in the substrate can be suppressed. The print head has an ink chamber communicating with an ink supply port. Furthermore, the print head has: a plurality of nozzle groups each of which is formed as one unit by combining a plurality of: communication ports that are provided in the ink chamber and that communicate with the ink supply port; pressure chambers including heat generating elements, ink supply ports, and ejection ports. A plurality of nozzle groups are formed in the same substrate and form a plurality of nozzle group arrays that are formed by the nozzle groups and that extend in the same direction. The plurality of nozzle group arrays are formed to be offset from one another in the direction along which the nozzle group array extend. | 08-12-2010 |
20140313259 | LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS - The present invention provides a liquid ejecting head provided with a suction port capable of avoiding the return of mists, which have once sucked through a suction port, to the suction port. In view of this, the inner diameter L of a suction tube for allowing liquid mists taken in through the suction port to pass is designed such that a meniscus is formed before a liquid droplet adhering to the inside of the suction tube grows enough to move toward the suction port. | 10-23-2014 |
20150085014 | LIQUID EJECTION APPARATUS, MIST COLLECTING MECHANISM AND MIST COLLECTION METHOD - There are provided a mist collecting mechanism capable of efficiently sucking and collecting an air blown out from a blow-out unit and a liquid ejection apparatus including the mist collecting mechanism. The mist collecting mechanism includes a suction port configured to suck an air containing mists. Moreover, the mist collecting mechanism includes a first blow-out port that blows out an air in order to guide the air containing mists to the suction port. Moreover, the mist collecting mechanism includes a second blow-out port that blows out an air in order to adjust a position, toward which the air blown out from the first blow-out port flows, so that the air blown out from the first blow-out port is appropriately sucked by the suction port. | 03-26-2015 |
20150085015 | PRINTING APPARATUS - Air blown out from one blowing-out opening of a pinch roller which is within a predetermined angle range forms an air flow of a flow rate Fc which heads for a region between a suction mechanism and a print medium. This makes it possible to efficiently guide the air blown out from the blowing-out opening into the region, and as a result, ink mist can be collected satisfactorily even in a case where the amount of air blown from the pinch roller is relatively small. Further, in this case, the flow rate Fe of a flow blown from the pinch roller is appropriately determined, whereby the suction mechanism can collect substantially 100% of air and ink mist flowing into the region. | 03-26-2015 |

20140147254 | VARIABLE DISPLACEMENT EXHAUST TURBOCHARGER EQUIPPED WITH VARIABLE NOZZLE MECHANISM - A variable displacement exhaust turbocharger is provided with a plurality of nozzle vanes that are rotatably supported by a nozzle mount, a drive ring that is interlocked with an actuator and fits to a guide part of the nozzle mount, a lever plate having one end coupled to the drive ring and the other end coupled to the nozzle vane, and a variable nozzle mechanism that varies the vane angle of the nozzle vane by rotating the drive ring. A bulge suppressing portion is provided for absorbing bulging occurring on an outer peripheral surface of the guide part, the bulging being caused by the press-fitting of a nail pin into a press-fitting hole in a direction slightly toward the rotational axis with respect to the guide section and following the axial direction of the nozzle mount. | 05-29-2014 |
20140161595 | VARIABLE DISPLACEMENT TURBOCHARGER AND ASSEMBLY METHOD OF VARIABLE NOZZLE MECHANISM - It is provided with: a variable nozzle mechanism for regulating a flow of exhaust gas to a turbine rotor; a link mechanism for converting reciprocal displacement from an actuator that operates a variable nozzle mechanism into rotational displacement and transmitting the rotational displacement to an inner section of a bearing housing; and an engaging part for engaging an output section of the link mechanism and an input section of the variable nozzle mechanism, and the engaging part is constituted by a pin and a pin insertion slot where the pin is inserted, and a smooth surface is formed around an insertion position of the pin so as to guide a tip of the pin to the insertion position. | 06-12-2014 |
20140169947 | VARIABLE DISPLACEMENT EXHAUST TURBOCHARGER EQUIPPED WITH VARIABLE NOZZLE MECHANISM - It is intended to achieve weight reduction and production reduction of a nozzle mount for pivotably supporting a drive ring constituting a variable nozzle mechanism, and is characterized by: providing on an end face of a guide part | 06-19-2014 |
20140169949 | STOPPER STRUCTURE FOR REGULATING OPENING DEGREE OF NOZZLE VANE IN TURBOCHARGER | 06-19-2014 |
