Patent number: 9925070Abstract: This invention relates to a technique for hermetically sealing an artificial leg including a cylinder device. A rod member of the cylinder device extends from the inside to the outside of a shell structure of the cylinder device. The rod member is hermetically sealed at the periphery thereof by a bellows packing member. The bellows packing member comprises an inner bead, an outer bead which concentrically surrounds the outside of the inner bead, and a bellows packing body part which connects the inner and outer beads. The bellows packing body part includes corrugations, and each corrugation is less curved than an imaginary circle which is concentric with the inner bead and the outer bead. Both ends of each of the plurality of corrugations extend to the outer bead or are located at positions closer to the outer bead than the inner bead.Type: GrantFiled: August 30, 2012Date of Patent: March 27, 2018Assignee: NABTESCO CORPORATIONInventors: Yoshiaki Nakaya, Taishiro Misao, Hiroaki Hashimoto, Nobuyuki Nakamura, Yoshihiro Tada

Publication number: 20160367385Abstract: A prosthetic knee joint includes a knee portion coupled to the socket, a cylinder that is coupled to the knee portion and limits or aids operation of the knee portion, a knee angle sensor that directly or indirectly detects a knee angle value, and a control unit that controls driving of the cylinder. The control unit may calculate a knee angular velocity value based on the knee angle value detected by the knee angle sensor. The control unit determines whether the knee portion is in a knee still state based on the knee angular velocity value and automatically restricts contraction of the cylinder based on a time duration in which the knee portion is in the knee still state.Type: ApplicationFiled: June 15, 2016Publication date: December 22, 2016Inventors: Hiroaki HASHIMOTO, Yoshiaki NAKAYA, Masakazu SAITO, Yoshihiro TADA, Taishiro MISAO, Masahiko OKUDA

Publication number: 20150250622Abstract: This invention relates to a technique for hermetically sealing an artificial leg including a cylinder device. A shell structure surrounds the outside of the cylinder device. The cylinder device is not entirely received within the shell structure, but a rod member extends to the outside of the shell structure from the cylinder body within the shell structure and a part of the rod member is located outside the shell structure.

Patent number: 6646905Abstract: A ferroelectric storage device having 2Tr-2C cell structure or 1Tr-1C cell structure, which can be assessed by a screening test. In the test, a regulated reference voltage is supplied from an external reference voltage input terminal to one end of a sense amplifier. The bit line voltage of the memory cell is input to the other terminal of the sense amplifier. Characteristics of the ferroelectric capacitor are determined quantitatively by measuring the bit line voltages by changing the reference voltage. Deviations in characteristics and degrees of defect/degradation of ferroelectric capacitors can be assessed by such measurement to improve the reliability of the ferroelectric storage device.Type: GrantFiled: January 8, 2002Date of Patent: November 11, 2003Assignee: Rohm Co., Ltd.Inventor: Yoshihiro Tada
