摘要： In a planetary bearing structure equipped with a slide bearing mounted to a shaft hole of a planetary gear, the planetary gear rotating about the outer periphery of a planetary pin fixed to a carrier via the slide bearing, one or a plurality of oil supply grooves are formed in the outer peripheral surface of the planetary pin so as to extend in the axial direction. An oil supply port of a lubricant oil channel opens in the oil supply groove so as to forcedly supply lubricant oil. Furthermore, a discharge groove for trapping foreign matter, which is shallower than the oil supply groove, communicates from the oil supply groove to the wake flow side in the rotating direction of the planetary gear.

摘要： In the ink jet head unit of the present invention, an ink jet head for emitting ink in a form of droplets from nozzles formed in a nozzle face and a driving circuit for driving the ink jet head are mounted on the same surface side of the base board. A groove section is formed in the surface, extending from the nozzle face of the ink jet head to the driving circuit. In the ink jet head, a temperature measuring section is positioned in the groove section. Furthermore, there is provided a sealing member in the groove section, to prevent the flow of ink emitted from the nozzles, into the driving circuit. The sealing member is partly formed of an elastic body. Therefore, since the elastic body can restrain a change in the volume of the sealing member likely to be caused by a temperature change, it is possible to prevent the temperature change from impairing the ink jet head, consequently realizing ink projection stability.

摘要： In such a manner that ink in each of a plurality of pressure chambers for holding the ink therein is brought to a positive pressure state of being ejected from respective nozzles respectively communicating with the respective chambers to the outside of each of the pressure chambers, a cleaning member abutted against a nozzle plate formed with a plurality of nozzles is moved along the nozzles in a state in which pressure is applied to all of the pressure chambers, to thereby extrude foreign particles outside the pressure chambers by the ink ejected from the respective nozzles to the outside of the pressure chambers, thereby making it possible to recover the ink, whereby the occurrence of a delivery failure due to the foreign particles around the nozzles being absorbed into the pressure chambers, can be prevented, and the foreign particles contained in the ink can be purged without consuming much ink needlessly.
