    Abstract: An ion beam apparatus comprises a source of ions (1), an evacuatable chamber (11), first and second electrodes (3,5) disposed within the chamber for forming an ion beam from ions from the ion source, the first electrode being electrically insulated from the second electrode. First and second supports for (17,19) supporting said first and second electrodes, respectively, are provided. The apparatus is arranged to allow said electrodes to be moved independently of one another relative to said chamber from outside said chamber.

    Abstract: A liquid ejection method includes preparing a head comprising an ejection outlet for ejecting the liquid, a bubble generation region for generating the bubble in the liquid, a movable member disposed faced to the bubble generation region and displaceable between a first position and a second position further from the bubble generation region than the first position; displacing the movable member from the first position to the second position by pressure produced by the generation of the bubble in the bubble generating portion to permit expansion of the bubble more in a downstream side closer to the ejection outlet than in an upstream side; supplying, to a heat generating element for applying thermal energy to the bubble generating region, a driving pulse divided into a first pulse and an adjacent second pulse with interval time therebetween; pre-heating the liquid by the first pulse to an extent not enough to eject the liquid through the ejection outlet; generating a bubble by heating the liquid by the second pulse to eject the liquid through the ejection outlet; controlling a degree of pre-heating of the liquid by changing at least one of a pulse width of the first pulse or the interval time.

    Abstract: A tone gradation recording method, comprising: providing a liquid ejection outlet; providing a first liquid flow path for first liquid in fluid communication with said liquid ejection outlet; providing a second liquid flow path for second liquid, adjacent to said first liquid flow path; providing a separation wall having a movable member between said first liquid flow path and said second liquid flow path; and ejecting, by displacement of said movable member toward said first liquid flow path, liquid which is a mixture of the first liquid and an amount of the second liquid on the basis of the amount of said first liquid, wherein the amount is controlled in accordance with the tone level to be recorded.
