| 20090057227 | LIQUID DELIVERY DEVICE, LIQUID CHROMATOGRAPH, AND METHOD FOR OPERATION OF LIQUID DELIVERY DEVICE - The present invention provides a liquid delivery device for liquid chromatographs which, by performing liquid delivery at an accurate flow rate with limited pulsation, gives accurate results of analyses. The present invention, with a view to preventing erroneous operation due to errors in measurements at the time of judgment of completion of compression of liquid, establishes the judgment point before the pressure measured by a cylinder pressure detector agrees with the pressure measured by a discharge pressure detector and also calculates the point of completion of compression. Control in this manner prevents pressure fluctuation. It also calculates for control the point of completion of compression from the history of compression performed previously. | 03-05-2009 |
| 20090090173 | LIQUID CHROMATOGRAPHY APPARATUS AND LIQUID CHROMATOGRAPHY ANALYSIS METHOD - An object of the present invention is to improve the accuracy in analysis repeatability of a liquid chromatography apparatus that feeds different eluent by use of a plurality of pumps and achieves the mixture of eluent. | 04-09-2009 |
| 20090193879 | SOLVENT DELIVERY DEVICE AND ANALYTICAL SYSTEM - Disclosed herein is a stable solvent delivery device capable of delivering solvent both at high pressure and at constant flow rate. | 08-06-2009 |

| 20090126722 | LIQUID EJECTION DEVICE AND EJECTION METHOD - A liquid ejection device, includes: a plurality of storing parts for storing liquids; a plurality of liquid-feeding parts connected to the respective storing parts; a ejection part for ejecting a liquid; a plurality of flow paths connected to the plurality of liquid-feeding parts, respectively; and a connection part for joining the plurality of flow paths and connecting them as a single flow path to the ejection part. The plurality of liquid-feeding parts are actuated to mix the liquids from the plurality of storing parts in the single flow path joined at the connection part and feed a mixture of the liquids to the ejection part to eject the mixture from the ejection part. According to the ejection device of the present invention, the ejection amount or the mixing ratio can be easily changed in a comparatively precise manner. | 05-21-2009 |
| 20090260624 | LIQUID EJECTION HEAD AND LIQUID EJECTION HEAD CARTRIDGE - A liquid ejection head to be used for an inhaler ejecting a liquid and making a user inhale the liquid includes: an ejection element having a liquid feeding opening, electrothermal transducer rows that are arrayed on both sides thereof respectively so as to sandwich the liquid feeding opening and are formed of a plurality of electrothermal transducers, and ejection nozzles for ejecting the liquid being provided on parts opposing to the electrothermal transducers respectively; and an external connecting terminal member for applying an electrical signal to the plurality of the electrothermal transducers, wherein, the external connecting terminal member is arranged so that a width direction in one end of its longitudinal direction matches with a direction of the electrothermal transducer rows and has a region for external connecting terminal on the other end of the longitudinal direction. | 10-22-2009 |
| 20100006094 | INHALER - An inhaler includes an inhaler body having an ejection head and an airflow duct forming member for forming an airflow duct on the inhaler body. In an inhalation standby status, the airflow duct forming member is driven to slide so as to be placed at rest on the inhaler body to partly cover the top part of the latter by means of a slide mechanism and make the airflow duct disappear. At this time, the top wall of the airflow duct forming member covers the ejection head to shield it from external air. In an inhalation status, the airflow duct forming member is driven to slide up and produce an airflow duct on the inhaler body. Thus, a compact inhaler that can be switched from an inhalation status to an inhalation standby status and vice versa with ease is realized. | 01-14-2010 |
| 20100024812 | INHALER - A cartridge having an ejection head for ejecting medicine and a reservoir as integral parts thereof is provided with an electric connection section on a lower surface of a junction forming section thereof to be brought into contact with an inhaler body. As the cartridge is put into the inhaler body and secured to the latter by means of a cartridge fixing member, the electric connection section of the cartridge is brought into contact with an electric connection section arranged on a top surface of a cartridge mounting section of the inhaler body to establish electric connection between the cartridge and the inhaler body. | 02-04-2010 |
| 20100186738 | LIQUID CARTRIDGE - A liquid cartridge of the present invention has a liquid ejection portion | 07-29-2010 |
| 20100288270 | LIQUID EJECTING HEAD - A liquid ejecting head includes an energy generating element for generating energy utilized for ejecting liquid containing a medicine, and a plurality of ejection outlets, provided for said energy generating element, for ejecting the liquid. Each of the ejection outlets has a rotationally asymmetrical cross-section in a plane parallel to the energy generating element. | 11-18-2010 |
