Publication number: 20240053053Abstract: An air purifier includes a housing having an air inlet, an air outlet, and a cavity portion connecting the air inlet and the air outlet, two blowers disposed in the cavity portion and each including a fan rotatable to generate a flow of air, and a filter disposed in the cavity portion. During rotation of the fan, the two blowers each suck in air from outside of the housing through the air inlet into the cavity portion, and blow the air having passed through the filter from the air outlet to the outside of the housing. A direction in which the air inlet is open crosses a direction in which the air outlet is open. An opening area of the air outlet is smaller than an opening area of the air inlet.Type: ApplicationFiled: October 26, 2023Publication date: February 15, 2024Inventors: Naokatsu Osawa, Ryuta Iijima, Keisuke Omori, Masashi Ichihashi, Junji Yamano

Publication number: 20230233973Abstract: An air purifier includes a housing, a first blower, a second blower, and a filter. The housing has a cavity inside, an inlet and an outlet. The first blower has a first fan in the housing. The second blower has a second fan in the housing. The second blower faces the first blower in an opposing direction. The inlet is located between the first blower and the second blower in the opposing direction. The inlet opens in a direction intersecting the opposing direction. The first fan of the first blower and the second fan of the second blower generate airflow such that air flows into the cavity through the inlet, and flows from the cavity through the filter to the outlet.Type: ApplicationFiled: March 29, 2023Publication date: July 27, 2023Inventors: Naokatsu Osawa, Koki Furukawa, Hiroki Sugamata, Masashi Ichihashi, Junji Yamano, Keisuke Omori, Ryuta Iijima

Publication number: 20210045733Abstract: A suturing device includes first and second holding members, a plurality of needles, a needle moving mechanism, and a suture hook. The first and second holding members are configured to move toward and away from each other to sandwich therebetween edges of a cut. The needles are disposed at the first holding member and aligned in a needle arrangement direction with their points pointing to the second holding member. The needles are configured to hold a suture at tips thereof. The needle moving mechanism is configured to move the plurality of needles toward the second holding member. The suture hook is disposed at the second holding member and configured to move along the needle arrangement direction to catch the suture that has reached the second holding member via the edges of the cut by movement of the needles toward the second holding member by the needle moving mechanism.Type: ApplicationFiled: October 30, 2020Publication date: February 18, 2021Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventors: Naokatsu OSAWA, Ryuta IIJIMA, Masashi ICHIHASHI, Kohei TERADA

Patent number: 9240710Abstract: A vibration-powered generator (100) has a vibrating element (10) and a coil (40) arranged therearound, and is configured to obtain electromotive force by moving the vibrating element (10) relatively to the coil (40). The vibrating element (10) has a plurality of magnets (20a to 20d) arranged so as to oppose the pole-faces of the same polarity; end supporting portions (12, 13) which support the plurality of magnets from both ends in the direction of arrangement; and a cushioning (16). The cushioning (16) is held between the end supporting portion (12) and the magnet (20c), while being compressed under a stress exceeding the repelling force between the pole-faces of the magnets, so as to keep the magnets (20a to 20d) in a row without leaving a gap in between, overcoming the repelling force.Type: GrantFiled: March 21, 2012Date of Patent: January 19, 2016Assignee: SUMIDA CORPORATIONInventors: Mitsugu Kawarai, Takayuki Yamaguchi, Ryuta Iijima, Ryoya Takahashi, Keisuke Nishihara

Patent number: 8618702Abstract: A vibration energy generator includes a case, a coil, a permanent magnet, and a shield magnet. The case is elongated in one direction and is made from a nonmagnetic material. The coil surrounds around an outer surface of the case. The permanent magnet reciprocates inside the case along the one direction. The permanent magnet is magnetized with a polarity oriented in the one direction. The shield magnet is disposed in one end portion of the permanent magnet in the one direction. Each of a surface of the one end portion and a surface of the shield magnet facing the surface of the one end portion has the same magnetic polarity. The length of the shield magnet in the one direction is less than the length of the permanent magnet in the one direction.Type: GrantFiled: March 28, 2012Date of Patent: December 31, 2013Assignee: Brother Kogyo Kabushiki KaishaInventor: Ryuta Iijima

Patent number: 6374024Abstract: An image sensor that is more compact than a contact type image sensor using a rod-lens array and has a depth of field of the same level as a contraction type image sensor using a set of mirrors. The sensor includes an array of a specified pixel-corresponding quantity of micro-lenses arranged for forming an image light reflected from an original document, an array of the specified pixel-corresponding quantity of optical fibers arranged for transmitting an image formed by the micro-lens array as respective optical signals of pixels and an array of light-receiving elements for converting optical signals incident thereon from the optical fiber array into electric signals, wherein the optical fiber array has core-end-faces each having a size smaller than that of an image formed by the micro-lenses and located on the micro-lens-side position from the image forming plane when the original document is placed at a specified base position.Type: GrantFiled: September 22, 1999Date of Patent: April 16, 2002Assignee: Sharp Kabushiki KaishaInventor: Ryuta Iijima
