Publication number: 20110169890Abstract: When a negative pressure is introduced into a closed space formed by a cap abutting to an ejecting head, the cap abuts to the ejecting head with a greater pressing force than that in a case where the negative pressure is not introduced into the closed space. Therefore, the cap can abut to the ejecting head with a weak pressing force during the time when the negative pressure is not introduced, it can be avoided that the cap abuts to the ejecting head with a significant pressing force over a long time, and collapse of the cap can be significantly suppressed.Type: ApplicationFiled: January 10, 2011Publication date: July 14, 2011Applicant: SEIKO EPSON CORPORATIONInventor: Keiji Hara

Patent number: 7690051Abstract: A harness type safety belt absorbs dropping shocks to a user who accidentally falls from an elevated position. If the user fails to apply a rope hook to a life line and falls from the elevated position, an air bag in a mounting body inflates to absorb the dropping shock to reduce the dropping impact applied to the user. If the user falls with the rope hook connected to the life line, the rope suspends the user. The body of the user is supported by a waist belt, shoulder belts and thigh belts. Therefore a tension applied by the rope to the body of the user is dispersed to each of the belts so the body of the user is stably supported.Type: GrantFiled: March 11, 2005Date of Patent: April 6, 2010Assignee: Prop Co., Ltd.Inventors: Mitsuya Uchida, Satoshi Teranishi, Keiji Hara, Tsuyoshi Kageyama

Publication number: 20090019623Abstract: The present invention provides a harness type safety belt capable of absorbing a dropping shock to a user even if the user accidentally falls from an elevated position. According to the present invention, in such a case that a user A fails to apply a hook of a rope to a life line and the user A falls from an elevated position, an air bag 2 provided in a mounting body 1 is inflated. Therefore, the air bag 2 can absorb a dropping shock and the dropping impact applied to the user A can be reduced. In addition, in the case where the user A falls with the hook of the rope being connected to the life line, the user A is suspended by the rope. The body of the user A is supported by not only a waist part belt 1b but also shoulder part belts 1a and thigh part belts 1c. Therefore a tension applied from the rope to the body of the user can be dispersed to each of the belts 1a, 1b and 1c and the body of the user can be stably supported.Type: ApplicationFiled: March 11, 2005Publication date: January 22, 2009Inventors: Mitsuya Uchida, Satoshi Teranishi, Keiji Hara, Tsuyoshi Kageyama

Patent number: 7357719Abstract: When a character is lent from a first game device to a second game device, clocks of those two game devices are synchronized, a shared lending/borrowing expiration time is set, the use of the character is temporarily disabled in the first game device, and the use of the character is temporarily enabled in the second game device. Then, a character return timing is determined, based on a time of the clock and the lending/borrowing expiration time, in the respective game devices. In accordance with the determined timing, the use of the character is enabled in the first game device, and the use of the character is disabled in the second game device. Thus, it is possible to lend/borrow a character as an item in the real world without generating a copy thereof, and the lent character is sure to be returned at the expiration of a predetermined lending/borrowing period.Type: GrantFiled: September 5, 2003Date of Patent: April 15, 2008Assignee: Nintendo Co., Ltd.Inventors: Satoshi Yamato, Nobuhito Koganezawa, Daisuke Tsujimura, Masanobu Suzui, Hirotaka Watanabe, Mitsuru Shinohara, Keiji Hara
