| 20090067888 | TONER CONTAINER HAVING TONER AGITATING FUNCTION - A toner container is mounted to an image forming apparatus in a state of containing toners. The toner container includes: a container body for containing toners; and an agitating unit provided in the container body for agitating the toners. The agitating unit includes: a cylindrical member having a cylindrical peripheral wall and rotating about an axis of cylinder; an opening formed in the cylindrical peripheral wall for allowing the toners to pass through; and a conveying section for conveying the toners in a direction of the axis of the cylindrical member. | 03-12-2009 |
| 20100254740 | SHEET REVERSING DEVICE AND IMAGE FORMING APPARATUS - A sheet reversing device has a vertical first conveyance path, a horizontal second conveyance path into which a sheet is carried via the first conveyance path and a horizontally third conveyance path into which the switched-back sheet is carried from the second conveyance path. A curved guide plate is disposed between the first and second conveyance paths and includes a curved guide surface for guiding the sheet to the second conveyance path, and a pivotal guide pivotably supported with a part thereof projecting from the curved guide surface. The pivotal guide pivots to retract into the inner side of the curved guide by being pushed by the sheet moving from the first conveyance path toward the second conveyance path while guiding the sheet switched back and carried out from the second conveyance path toward the third conveyance path with the part thereof projecting from the curved guide surface. | 10-07-2010 |

| 20080218030 | ULTRASONIC TRANSDUCER - An ultrasonic transducer includes a cylindrical cap member having a bottom. A piezoelectric element is bonded to the inner side of a bottom portion of the cap member using a conductive adhesive or other suitable adhesive. An inner frame made of a material having an acoustic impedance greater than that of the cap member is fitted into the cap member so as to be in contact with a side portion, including the end portion, of the cap member. Through-holes are provided in the side portion of the inner frame. Lead wires are connected to the piezoelectric element and the inner frame, respectively. A sound absorber and a damper are inserted into the inner frame. The damper is in direct contact with the side portion of the cap member via the through-holes of the inner frame. | 09-11-2008 |
| 20090195123 | ULTRASONIC SENSOR - An ultrasonic sensor includes a cylindrical outer case with a bottom and a piezoelectric element fixed to the inner side of the bottom portion of the outer case. A ring-shaped inner case having a central hole extending in the axial direction in the central portion thereof is disposed inside the sidewall portion of the outer case. A flat or substantially flat portion is provided around the central hole of the inner case, and a viscoelastic filler is arranged so as to extend from the central hole to the flat or substantially flat portion of the inner case. A tabular member is disposed on the flat or substantially flat portion so as to face the flat or substantially flat portion with the filler interposed therebetween. When the inner case vibrates, shear deformation occurs in the filler interposed between the flat or substantially flat portion and the tabular member since the tabular member is not substantially deformed, and the vibration is reduced by the viscoelastic damping effect. | 08-06-2009 |

| 20080279268 | Method for measuring noise, apparatus for measuring noise, and program for measuring noise - The frequency of signals under test is stabilized and the noise components of the signals under test whose frequency has been stabilized is measured. When the noise of the object under test is related to frequency or phase, the measured noise components are corrected based on the properties of frequency stabilization. | 11-13-2008 |
