| 20080217974 | Child Motion Device - A child motion device includes a frame that provides a structural support relative to a reference surface and that includes an arm pivotably coupled to the structural support. A child supporting device is coupled to the arm and spaced from the reference surface by the frame. A drive system is configured to move the arm such that the child supporting device reciprocates along a motion path at a frequency within a range from about 0.37 Hz to about 0.62 Hz. In some cases, a further drive system is configured to oscillate the child supporting device generally along the axis of rotation at a frequency in a range from about 2.85 Hz to about 3.15 Hz. | 09-11-2008 |
| 20080238163 | Seat Support Structure for a Child Motion Device - A child motion device has a frame assembly configured to rest on a floor surface, a drive system defining a generally vertical axis of rotation, and a support arm supported above the floor surface by the frame assembly. The support arm is cantilevered from near the axis of rotation and has a driven end coupled to the drive system, which pivotally reciprocates the support arm through a partial orbit around the axis of rotation, A seat holder is carried by the support arm spaced from the driven end and a seat is supported by the seat holder. The seat and seat holder are constructed to permit the seat to be removed from the seat holder. The seat is usable as a seat when removed from the seat holder and can be positioned on the seat holder in more than one optional seat facing orientation. | 10-02-2008 |
| 20090170618 | Child Motion Device - A child motion device has a frame assembly configured to rest on a floor surface. The device also has a drive system that defines a generally vertical axis of rotation. An arm extends from part of the device and is cantilevered from the axis of rotation. The arm is supported above the floor surface and has a driven end coupled to and movable by the drive system and a distal end opposite the driven end. The drive system is configured to pivotally reciprocate the arm through a partial orbit around the axis of rotation. A child seat is supported on the distal end of the support arm. | 07-02-2009 |

| 20100277523 | Liquid Ejection Apparatus And Head Maintenance Method - A liquid ejection apparatus includes: an inkjet head including a plurality of nozzles which eject liquid containing a water-soluble high-boiling-point organic solvent having an SP value of 30 or lower at a concentration of 10 weight percent or higher and 25 weight percent or lower, a plurality of liquid chambers connected to the plurality of nozzles respectively, and a plurality of supply flow channels to any of which each of the plurality of nozzles is connected and which supply the liquid to the plurality of nozzles via the plurality of liquid chambers; a capping device configured to simultaneously cap the nozzles connected to the same supply flow channel, from a liquid ejection surface side of the inkjet head; a pressure application device which applies pressure to the liquid inside the nozzles via the capping device; and a pressure control device which controls the pressure application device so as to repeat pressurization and depressurization with respect to the liquid inside the nozzles. | 11-04-2010 |
| 20110085012 | DROPLET EJECTION HEAD, DROPLET EJECTION APPARATUS, AND METHOD OF COLLECTING BUBBLES IN DROPLET EJECTION HEAD - The droplet ejection head includes: a plurality of droplet ejection units which include ejection ports through which droplets of liquid are ejected, pressure chambers which are connected to the ejection ports through connection channels, drive elements which apply pressure to the liquid in the pressure chambers, supply channels through which the liquid is supplied to the pressure chambers, and return channels through which the liquid is returned from the connection channels; a common supply channel through which the liquid is supplied to the supply channels; and a common return channel through which the liquid is returned from the return channels, the common return channel including a stagnant flow region having a bubble collection section where bubbles are collected, wherein pressure variation occurring in each pressure chamber when ejecting a droplet of the liquid propagates more readily in the common return channel than in the common supply channel. | 04-14-2011 |

| 20110234676 | METHOD OF PRINTING TEST PATTERN AND INKJET RECORDING APPARATUS - A test pattern is printed for ascertaining ejection characteristics of nozzles arranged in a recording head in an inkjet recording apparatus which forms and records a desired image on a recording medium by performing ejection of droplets of liquid from the nozzles and deposition of the droplets onto the recording medium. Ejection of droplets of the liquid from the recording head is performed by applying, to the recording head, a drive signal having a test waveform in which at least one of a voltage, a frequency and a waveform shape is altered with respect to a drive signal having a recording waveform which is applied to the recording head when the desired image is formed, to thereby perform the ejection with an increased ejection force compared with a case where the drive signal having the recording waveform is applied; and the test pattern is formed by the ejected droplets. | 09-29-2011 |
