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
20090260624LIQUID 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
20100006094INHALER - 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
20100024812INHALER - 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
