Publication number: 20080214961Abstract: In a process of varying pressure of a pressure container (24) accommodating a forearm (22) of a subject (20) in a pressure range including negative pressure, a diameter (cross-sectional shape value) (D) of an artery 44 in the forearm (22) accommodated in the pressure container (24) is measured non-invasively by a vascular diameter calculating unit (76). In addition, a display controller (display controlling means) (80) operates to display on a displaying device (16) a variation of an internal pressure (Pc) in the pressure container (24) and a variation of the diameter (D) of the artery (44) varying depending thereon. Based on the diameter (D) of the artery (44) obtained in the high pressure region, the variation of the internal pressure Pc in the pressure container 24 and the variation of the diameter (D) of the artery 44 varying depending thereon i.e. mechanical properties of the artery (44) are displayed on the displaying device (16).Type: ApplicationFiled: February 27, 2008Publication date: September 4, 2008Applicant: UNEX CORPORATIONInventors: Takeo Matsumoto, Kazuaki Nagayama, Kenji Takezawa, Hiroshi Masuda

Patent number: 7152444Abstract: A press forming machine comprising driving shafts for pressing three or more respective pressure points and displacement measuring means for measuring a displacement close to the pressure point. A central driving shaft among the driving shafts has a gap (the slack) larger than those of other driving shafts between each of the driving shafts and a pressure plate. During press formation at a trial stage, a positional displacement close to each pressure point is measured by the displacement measuring means and control data is supplied to each driving source for driving a driving shaft to drive the pressure plate. Then, production press-formation is performed in accordance with the above result. Therefore, the central driving source can avoid overload by the slack of the driving shaft with the pressure plate.Type: GrantFiled: March 23, 2004Date of Patent: December 26, 2006Assignee: Hoden Seimitsu Kako Kenkyusho Co., Ltd.Inventors: Takeo Matsumoto, Shoji Futamura
