摘要： An ink jet recording head includes ejection electrodes arranged along ink paths that each have an ink outlet at one end and communicate with an ink chamber at the other end. The ejection electrodes are arranged in electrode sets, each set consisting of a number of ejection electrodes. The electrode sets have their corresponding ejection electrodes short-circuited, and are provided with control electrodes that are each common to respective ejection electrodes of a corresponding electrode set, and that are rearwardly offset from front ends of the ejection electrodes in an ink discharge direction. A voltage driver selectively imposes a voltage to groups of electrodes to provide a discharge biasing function, and selectively imposes a lower potential than a potential of the ejection electrodes to the control electrodes to provide a discharge restricting function.

摘要： An electrostatic ink jet recording head of a drop-on-demand type has a head body defining an ink chamber for receiving liquid ink containing charged toner particles, a set of electrodes for migrating the liquid ink by electrophoresis and ejecting the liquid ink from an ejecting slit of the ink chamber, and an ink reservoir, disposed above the ink chamber, for circulating the liquid ink by gravity between the ink reservoir and the ink chamber. A flow resistance against the liquid ink in the flow path from the outlet port of the ink chamber to the ink reservoir is smaller than a meniscus force generated by meniscuses formed at the ejecting slit to effectively eject the liquid ink without a pump and without an ink leakage.

摘要： An electrostatic ink jet recording apparatus has a head body having an ink chamber in which ink charged to a specified polarity is stored, a plurality of ink ejection ports and a plurality of ejection electrodes. An ejection electrode drive circuit generates an ejection voltage to drive the plurality of ejection electrodes according to a time division method so that the ejection voltage is not simultaneously supplied to the adjacent ejection electrodes. A plurality of opposite electrodes are opposed to the plurality of ejection electrodes via recording paper. They are separated into first opposite electrodes corresponding to those ejection electrodes which are selectively being driven according to the time division method and second opposite electrodes corresponding to those ejection electrodes which are not being driven according to the time division method. An opposite potential setting circuit sets a first potential for the first opposite electrodes and a second potential for the second opposite electrodes. The first potential is set at such a value as to cause ink ejected from the ink ejection ports to be electrically attracted to the first opposite electrodes more strongly than to the second opposite electrodes.

摘要： The invention relates to an ink-jet printer which uses an ink containing fine solid particles of a pigment suspended in a carrier liquid. The print head of the printer has an ink ejection orifice at one end of an ink chamber, and the ink chamber is provided with a first electrode to which a first DC voltage is applied for concentrating the pigment particles in the vicinity of the orifice by electrophoresis and a second electrode to which a second DC voltage in pulse form is applied for ejecting an agglomeration of the pigment particles together with a small amount of carrier liquid from the orifice. In the printer, the length of waiting time, which elapses from the decay of a pulse of the second voltage, is checked. When the waiting time is relatively long, the polarity of the first voltage is inverted to prevent excessive concentration of pigment particles in or in the vicinity of the orifice, and/or the second voltage is modified to promote movement of pigment particles in the vicinity of the second electrode toward the tip of the second electrode.

摘要： An ink jet type head has a plurality of ink ejection electrodes in a form of parallel strips formed on a base. The ink ejection electrodes include first ejection electrode and second ejection electrodes provided adjacent to two sides of the first ejection electrode. There is provided a voltage driving unit for applying an ejection voltage for ink ejection to the first ejection electrode. In the voltage driving unit, the ejection voltage to cause the ink to be ejected is applied to the first ejection electrode and an auxiliary voltage ineffective to cause the ink to be ejected is applied to the second ejection electrodes. This enables the reduction of potential differences between the first and second ejection electrodes, thus suppressing movement of color particles of the ink between them.

A cell holding member has a plurality of cells formed therein, one of which is placed at a predetermined detection position so that the solution flows through that cell. A concentration of the solute is detected based on the intensity of light that has passed through the cell placed at the predetermined detection position. A cell changer replaces the cell with another cell by moving the cell holding member when a detected concentration has not changed as expected.
