Publication number: 20240089344Abstract: A transmitting terminal can transmit a content held by itself to a specific receiving terminal having no email software as if using a mailer. The transmitting terminal (10) and the receiving terminal (20) are connected to a delivery server (30) via a network (4). The delivery server (30) comprises: a database (36) for registering the device ID that specifies the receiving terminal (20); a content storage (39) for temporarily storing a content transmitted from the transmitting terminal (10); and table (33, 37) for managing contents separately on a per device ID basis of the receiving terminal. The delivery server (30), when receiving a request from the receiving terminal (20), refers to the tables (33, 27) and transmits to the receiving terminal (20) a content, the transmission destination of which corresponds to the device ID of the receiving terminal (20).Type: ApplicationFiled: November 17, 2023Publication date: March 14, 2024Inventors: Hiroki Mizosoe, Junji Shiokawa, Kazuto Yoneyama, Kunihiro Nomura, Masaaki Hiramatsu, Yasuhisa Mori, Takashi Yoshimaru, Kazuaki Aoyama, Tomomu Ishikawa, Yo Miyamoto

Publication number: 20090300843Abstract: A postural change device used to allow imaging a plurality of postures while changing the posture of a portion to be examined of an object by means of a medical image diagnostic apparatus. The postural change device comprises a head-use balloon and a trunk-use balloon dispersedly arranged in a bag-form mat, and a compressor and a valve body carrying out parallel actions on the two balloons, that is, maximum expansion?medium expansion?complete contraction on the head-use balloon, and complete contraction?medium expansion?maximum expansion on the trunk-use balloon, whereby it is possible to sequentially change the cervical spine of the object from an anteversion posture to a neutral posture to a retroflexed posture.Type: ApplicationFiled: July 4, 2006Publication date: December 10, 2009Inventors: Taisuke Matsushita, Yutaka Sato, Kazuaki Hiramatsu, Makoto Konami, Shoujirou Asai

Patent number: 7413554Abstract: Provided is a wearable joint driving device in which a plurality of frame members are attached to a wearing body so as to be in contact with the outer surface of the wearing body. Between the frame members, there is mounted a fluid pressure type actuator. The fluid pressure type actuator has an expansion/contraction member and a net-like covering member covering the outer periphery of the expansion/contraction member. The fluid pressure type actuator undergoes a reduction in length through expansion of the expansion/contraction member to thereby generate a driving force. The frame members have a predetermined level of rigidity.Type: GrantFiled: March 18, 2004Date of Patent: August 19, 2008Assignees: Hitachi Medical Corporation, Tokyo University of ScienceInventors: Hiroshi Kobayashi, Yutaka Sato, Kazuaki Hiramatsu, Makoto Konami, Taisuke Matsushita, Masaaki Muromachi, Akitaka Uchimura
