Abstract: Ultrasonic flaw detection uses a phased-array ultrasonic-flaw-detection probe. The flaw detection probe is placed such that the center of curvature of the flaw detection probe coincides with a reference center of curvature of a subject. The flaw detection probe is translated along a scan direction. The flaw detection probe emits an ultrasonic beam such that the position upon which the ultrasonic beam converges coincides with the center of curvature of the curve of the outline of the cross section of the subject at the scan position, receives the resulting reflected beam, and estimates the length of a flaw in the circumferential direction of the subject. In addition, the estimated length of the flaw is corrected using a correction coefficient corresponding to the distance between the center of curvature of the reference scan position and the center of curvature of the scan position in the thickness direction of the subject.

Abstract: An imaging system includes a housing, a developer roller that transfers developer to an image carrier at a development region, a developer regulator to limit a thickness of the developer carried on the developer roller, and an air passage that extends outside a development chamber. The air passage has an inlet to draw an airflow, and an outlet located between the developer regulator and the development region. The air passage has a cross section orthogonal to a direction of the airflow from the inlet to the outlet. In the cross section taken at the narrowest position where the air passage is the narrowest, a width in a width direction parallel to a rotational axis of the developer roller is greater than a thickness that is perpendicular to the width direction.

Abstract: Provided is a single-axis hinge with a damper mechanism and a catch mechanism for allowing either one of a first member and a second member to be attached to a portion having a small attachment space. The single-axis hinge (2) includes the first member (11) attached to the main body, and the second member (12) which is attached to the door and can rotate with respect to the first member (11) around a shaft (13) facing a vertical direction. The catch mechanism (6) has a spring (8) and gives rotational force in a closing direction to the door in the vicinity of a closed position. The damper mechanism (7) has a linear damper (9) and damps rotation of the door when the door is closed. The catch mechanism (6) and the damper mechanism (7) are disposed on either one of the first member (11) and the second member (12).

Abstract: Two or more target points different in amplitude in a natural mode, which exist in a housing of an object to be damped such as an engine, a gearbox, motors, or the like are located. Among these target points, an arm is fixed at a position relatively small in amplitude, and a vibration absorber provided at the free end of the arm is pressed against a position (relatively large in amplitude. When vibrations occur in the object, the vibration absorber holds the target point relatively large in amplitude while the arm is following the vibrations of the target.

Abstract: A developing device includes a developer roller to rotate in a rotation direction, a photosensitive body adjacent the developer roller, and an air flow passage extending through a non-image forming region at a longitudinal end of the developer roller. A closest position is defined where the developer roller and a photosensitive body are closest to one another. The air flow passage extends from inside the developing device and forms an air flow directed toward an upstream side of the closest position, relative to the rotation direction of the developer roller.
