Publication number: 20110318824Abstract: An end portion of a head has a recess having an inner shape corresponding to a dome shape of a well when the well is in an expanded state. The radius of curvature of the recess is larger than the radius of curvature of the dome shape of the well. Moreover, the depth of the recess is smaller than the height of the dome shape of the well. Therefore, the head first contacts the apex of the well, and the contact area gradually expands toward the outer periphery. At this time, a gap is generated between the head and the cartridge around the well. Thus, the air between the head and the well is expelled from around the well as the head is pressed against the well.Type: ApplicationFiled: May 31, 2011Publication date: December 29, 2011Applicant: YOKOGAWA ELECTRIC CORPORATIONInventors: Takeo Tanaami, Hisao Katakura, Nobuyuki Kakuryu
