Patent number: 7703274Abstract: To provide a simple structured and low cost pintle injector capable of uniformly atomizing and mixing fuel and oxidizer, and further improving the combustion efficiency of the combustion reaction in the combustion chamber. A pintle injector part having a first propellant channel forms a first injector flow path as a regenerative cooling path along the pintle external wall that projects into a combustion chamber, and high temperature fuel gas is injected from the first pintle injector port. On the other hand, an axial injector part is located upstream of the first pintle injector port, and injects comparatively low temperature liquid or gas fuel from an axial injector port via a third propellant channel and a third injector flow path. Oxidizer is injected from a second pintle injector port via a second propellant channel and a second injector flow path, and is atomized and mixed while being impinged on either by the high temperature fuel gas and the comparatively low temperature liquid or gas fuel.Type: GrantFiled: April 14, 2006Date of Patent: April 27, 2010Assignee: Japan Aerospace Exploration AgencyInventors: Keiichi Hasegawa, Shinichi Moriya

Patent number: 7191044Abstract: Systems and methods for controlling the sensing of an occupant in a seating area are provided. The occupant is characterized as one of an adult, child or other category. One characterization change parameter, such as a hysteresis time period or thresholds for characterization, is applied for a first time period. After that time period, the characterization change parameter is changed. For example, if the characterization stays the same for ten seconds, the hysteresis is changed from five to ten seconds. As another example, if the characterization stays the same for one minute, the thresholds associated with that characterization are broadened to decrease the likelihood of a change in characterization. In some systems and methods, a confidence parameter or probability associated with the characterization is used to control the changes to the characterization change parameter.Type: GrantFiled: June 15, 2004Date of Patent: March 13, 2007Assignee: Elesys North America Inc.Inventors: Gregory T. Thompson, Shiuh-An Shieh, Keiichi Hasegawa, Svetoslav G. Stoyanov

Patent number: 7173724Abstract: A display section of a scanner is connected to a printer controller of a printer via a bus line, so that detailed information regarding the scanner the printer and so on is controlled by the printer controller. Both display contents respectively regarding the printer or the scanner are stored in a VRAM of the printer controller. Because of this, the detailed information regarding the printer is displayed on the display section of the scanner, which is a large LCD. This provides an image forming system, which notifies a user of the detailed information of the printer in a such manner that the user can easily understand the detailed information, when the scanner and the printer, each of which can be used independently, are combined as a system.Type: GrantFiled: December 20, 2001Date of Patent: February 6, 2007Assignee: Sharp Kabushiki KaishaInventors: Tatsuo Nomura, Yuhji Okamoto, Syoichiro Yoshiura, Kohki Fukuda, Keiichi Hasegawa, Seiji Takeda
