Patent number: 10291154Abstract: A driving device that causes a movable body to move stably with minimal backward movement. The driving device includes a plate-shaped driving unit with an elastic body and a piezoelectric element joined to a main surface of the elastic body. Moreover, the movable body is disposed into a cavity of the elastic body and is moved by being pitch fed when the driving unit is driven. The driving unit vibrates with flexural vibration and one more other vibration modes or with vibration of a coupled mode in which the flexural vibration and the other vibration mode are coupled with each other.Type: GrantFiled: May 25, 2016Date of Patent: May 14, 2019Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Seishiro Goto, Megumi Otsuka, Junichi Nomura, Koichi Hayashi

Patent number: 6495050Abstract: A treating method and apparatus for treating a manganese containing water by crystalizing and removing a soluble manganese in a water to be treated containing carbonic acid ions by passing the water to be treated as an upward flow through a fluidized bed reaction tower having no support bed and containing manganese sand as a fluidized bed material and by adjusting a pH value of the water to be treated in said fluidized bed. A suspended manganese is also removed together with said soluble manganese in the water to be treated by forming a suspended solid in the water to be treated into a layer on said manganese sand fluidized bed by removing said layer of suspended solid. Further, a desired quantity of the treated water is introduced into the water to be treated for circulatory use.Type: GrantFiled: December 18, 2000Date of Patent: December 17, 2002Assignee: Ebara CorporationInventors: Junichi Nomura, Shinichiro Egawa

Patent number: 4110138Abstract: A backing material for handcraft yarn arts comprises a foundation fabric having plural thermo plastic pile threads extending from one surface thereon in substantially upright direction with the free ends deformed by melting to assume enlarged, deformed configurations in a random and irregular pattern. Yarn of a generally soft or porous nature is placed in a desired pattern on the upstanding threads and loosely retained thereon while being readily removed to alter the pattern. When a final pattern is achieved, heat and pressure is applied, urging the yarn fully into and within the pile threads and further deforming the free ends into enlarged deformations for securely anchoring the yarn and providing a substantially permanent yarn part handcraft product.Type: GrantFiled: March 17, 1977Date of Patent: August 29, 1978Inventors: Junichi Nomura, Masashi Kanai
