A liquid ejecting apparatus, including an electric potential control unit capable of switching between an identical electric potential state which sets a predetermined region of the liquid ejection unit side and a predetermined region of the ejecting medium support unit side to the identical electric potential and an electric potential difference generating state which generates the electric potential difference between both of them, wherein the liquid ejecting apparatus includes a configuration in which, when the ejecting medium passes through a liquid ejecting area to which the liquid is ejected by the liquid ejection unit, the electric potential control unit forms the identical electric potential state, and when the ejecting medium does not pass through the liquid ejecting area, the electric potential control unit forms the electric potential difference generating state for at least a proper period.

In the liquid ejecting apparatus, a potential controller that is capable of switching states between a same potential state where potentials at a predetermined portion at the side of the liquid ejecting unit and a predetermined portion at the side of the ejected medium supporting unit are the same and a potential difference generation state where a potential difference is generated between the predetermined portion at the side of the liquid ejecting unit and the predetermined portion at the side of the ejected medium supporting unit. The potential controller forms the same potential state while the ejected medium is transported by the ejected medium transportation unit, and the potential controller forms the potential difference generation state in at least appropriate period while the ejected medium is not transported by the ejected medium transportation unit.

A liquid ejecting apparatus includes: a transport unit that transports a recording medium; a liquid ejecting head that ejects a liquid onto the recording medium; a carriage that holds the liquid ejecting head; a charge amount detection unit that detects a charge amount on the recording medium; and a driving control unit. In the case where the charge amount detected by the charge amount detection unit has exceeded a predetermined value, the driving control unit performs at least one of the following: controls the transport unit so that the transport speed of the recording medium becomes relatively slower.

An object is to provide a fine forging method for forming partitions of recesses precisely and forming recess shapes for pressure generation chambers etc. with high accuracy as well as a liquid ejection head that is produced by using the fine forming method. A fine forging method for forming groove-shaped recesses that are arranged at a prescribed pitch. After groove-shaped recesses are formed tentatively in a material plate by a first punch in which tentative forming punches are arranged, finish forming is performed on the tentatively formed groove-shaped recesses by using a second punch in which finish forming punches are arranged. An end portion of a projection strip is formed with slant faces or a slant face, whereby an end portion of each groove-shaped recess is formed precisely. A liquid ejection head produced by the above method exhibits stable liquid ejection characteristics and its manufacturing cost can be reduced by virtue of simplified working of forging.

A grinding type vertical grain milling machine is capable of shortening a dimension of a machine body in the vertical direction and removing bran by evenly suctioning an entire bran removing chamber. The grinding type vertical grain milling machine includes a bran removing metallic mesh cylinder with a main shaft, an integral grinding type grain milling roll body, a bran removing chamber, and a bran discharge pipe that discharges bran to the outside of the machine. A fan-pulley is provided between the bran removing chamber and the bran discharge pipe. The fan-pulley rotationally drives the main shaft to which the grinding type grain milling roll is axially attached and generates a bran removing wind to convey bran produced by the grain milling action of the grinding type grain milling roll from the bran removing chamber toward the bran discharge pipe.

A bran removing wire-mesh tube includes: bran removing wire-mesh tube parts 28 divided in more than one in a circumferential direction in planar view; and a plurality of support pillars 33 erected at intervals in the circumferential direction to respectively fix both side edges of the divided bran removing wire-mesh tube parts 28. Each of the support pillars 33 is provided with an elongated resistor 34 that suppresses grains from moving in the circumferential direction along with rotation of grinding type grain cleaning rolls 26. The resistor 34 is urged by an elastic member 37 to a position at which the resistor 34 protrudes toward the inside of a grain cleaning chamber 30. Further, the resistor 34 is provided so as to be movable in a radial direction to a position farther from the grain cleaning chamber 30 due to resistance from the grains.
