  • Patent number: 7881626
    Abstract: An image formation apparatus has a waste toner accommodation unit including a toner transporting rotation member covered with a fixed pipe. As the member rotates, waste toner in the pipe is transported downstream A fin involved in detecting an amount of toner moves upward and downward with a predetermined amplitude as the member rotates. The pipe has a projection secured by an elastic member to a bottom of the waste toner accommodation unit, and when waste toner reaches the level of the pipe, the waste toner is compressed in the pipe downstream and thus increases in density, and together with the waste toner the pipe starts to rotate. As a result, the projection rotates to a position allowing it to interfere with the fin, and the fin decreases in amplitude. Such variation in amplitude is detected by a sensor and a state full of toner is thus detected.

  • Patent number: 7660541
    Abstract: An image formation apparatus has a waste toner accommodation unit including a toner transporting rotation member covered with a fixed pipe. As the member rotates, waste toner in the pipe is transported downstream. The toner transporting rotation member has an upstream portion with a recessed portion having a small diameter. As the toner transporting rotation member rotates, a detection plate located external to the waste toner accommodation unit repetitively moves and thus repetitively passes across a photo sensor. When the waste toner has reached the level of the pipe the waste toner is compressed in the pipe downstream and thus increases in density. This increases a load torque of the toner transporting rotation member and hence ruptures the recessed portion, and thus stops rotation. The photo sensor detects that the detection plate no longer passes across it, and thus detects a state full of toner.

  • Patent number: 7207660
    Abstract: An electrostatic ink jet head has a head substrate, an insulating substrate having at least one through hole, an ink guide, ink supply means, a control electrode, and meniscus control means. An ink passage is formed between the head substrate and the insulating substrate. The meniscus control means controls fixing of an edge portion of an ink meniscus formed in proximity to the through hole or within the through hole. With the meniscus control means, it becomes possible to maintain the position and shape of the ink meniscus with stability, thereby allowing ejection and flying of liquid droplets, such as ink droplets, with stability and formation of an image of high quality on a liquid droplets reception member such as a recording medium.

  • Patent number: 7118200
    Abstract: The inkjet printer head includes heating elements and ejection nozzles. Each of the heating elements has a heating resistor which is energized by application of an electric current so that a part of ink which is located in proximity to the heating resistor is boiled to form a bubble. The expansion of the formed bubble causes the ink to be ejected as a droplet through each of the ejection nozzles. Each of said heating elements has no protective film disposed between the heating resistor and the ink in which the bubble is to be formed. A thickness of said heating resistor is in a range of from 2 ?m to 5 ?m.

  • Patent number: 7108584
    Abstract: The method and apparatus manufacture a liquid drop ejecting head. The method and apparatus blast particles on a substrate having on an upper layer a patterned mask layer made of an organic material and on a lower layer a driver circuit for ejecting a liquid drop to thereby perform an etching process on parts of the substrate exposed from the mask layer. The etching process is performed in an ionic atmosphere ionized with a polarity opposite to a charged polarity generated in the substrate when the substrate is subjected to etching.

  • Patent number: 7070262
    Abstract: The droplet ejecting head includes heating elements each of which has a thermal energy applying surface which imparts energy to a viscous fluid with a viscosity of at least 20 mPa┬Ěsec so as to evolve a bubble, fluid supply channels each of which has the heating element on a wall and supplies the fluid toward the heating element and ejection nozzles through each of which the fluid is ejected as a droplet and each of which is in a position opposite the energy applying surface of the heating element across the supply channel. A distance between the energy applying surface and a foremost end of the ejection nozzle from which the droplet is ejected is in a range of from 2 ?m to 8 ?m or the distance is smaller than a growth height of the bubble that has evolved in the fluid by means of the heating element and which has been left to expand by itself until its internal pressure once exceeding one atmosphere decreases to a point below one atmosphere.
