Patent number: 7230366Abstract: In a vibration wave linear motor, a vibrator stably operates with a simple and small configuration. Both ends of a movable guide member are held by shaft bearing long holes to freely oscillate, and an angle of an inclination ? occurs according to the move of the vibrator. An inner wall of an erecting part of a supporting part also serves as a stopper, and regulates the move of the vibrator in a position where the inclination of the movable guide member becomes ?>? at the maximum. As a result, the inclination of the movable guide member is always kept to be within the range of ?>?. A problem that the inclining movable guide member contacts a portion other than a driving contacting part is prevented.Type: GrantFiled: September 28, 2004Date of Patent: June 12, 2007Assignee: Olympus CorporationInventors: Yasuo Sasaki, Heiji Ogino, Toshihiro Nakao

Patent number: 7205703Abstract: In an ultrasonic vibrator in which ultrasonic elliptical vibration is caused at a friction-projection by the simultaneous generation of a first vibration mode and a second vibration mode in a piezoelectric element, the friction-projection is formed by burning so as to be integrated with the piezoelectric element.Type: GrantFiled: September 15, 2004Date of Patent: April 17, 2007Assignee: Olympus CorporationInventors: Tomoki Funakubo, Heiji Ogino

Patent number: 7157832Abstract: A vibration wave linear motor comprises a vibrator unit having two driving contacting parts which are respectively formed on top and bottom surfaces of the vibrator unit, two guide members guiding the running of the vibrator unit by sandwiching the vibrator unit in parallel with the running direction. The upper guide member is fixed to the supporting member. The lower guide member is held in shaft bearing long holes, pressed upward by coil springs within hollow convex parts. The vibrator unit self-runs and moves forward and backward between the two guide members with an ultrasonic vibration. A linking pin fixed on the side surface of the vibrator unit engages with the member to be driven, so that moving force is transmitted.Type: GrantFiled: July 29, 2004Date of Patent: January 2, 2007Assignee: Olympus CorporationInventors: Yasuo Sasaki, Toshihiro Nakao, Heiji Ogino

Patent number: 7053525Abstract: An ultrasonic linear motor according to the present invention has a configuration wherein driving elements are glued at portions on faces of an ultrasonic transducer, facing one another, where rotational directions of elliptic vibrations generated on the faces are reverse one to another, a pair of guides are provided for being pressed into against the driving elements so as to hold the ultrasonic transducer therebetween, and leaf springs serving as pressing part are provided so as to narrow a spacing between the one pair of guides, whereby the ultrasonic transducer is configured as an self-moving ultrasonic linear motor which can drive by itself. Thus, driving properties of the ultrasonic transducer itself is improved, and also the size of the ultrasonic linear motor can be reduced.Type: GrantFiled: March 31, 2003Date of Patent: May 30, 2006Assignee: Olympus CorporationInventors: Tomoki Funakubo, Yasuo Sasaki, Kiyoshi Tosaka, Heiji Ogino, Takashi Kawashima, Toshihiro Nakao

Patent number: 4264184Abstract: An ozone removing device for electrographic apparatus comprising a photosensitive screen and a corona discharge device for producing a harmful ozone is disclosed. The device comprises a casing substantially hermetically surrounding said photosensitive screen, an air circulating device for circulating an air stream through said corona discharge device in said casing and a catalyst device arranged in said air circulating device and for decomposing ozone produced from said corona discharge device, whereby said ozone is sucked into the outside of said casing by means of said air circulating device and decomposed and then flowed back into said casing again.Type: GrantFiled: June 25, 1979Date of Patent: April 28, 1981Assignee: Olympus Optical Co., Ltd.Inventors: Masaji Nishikawa, Hiroshi Furuhashi, Heiji Ogino
