  • Publication number: 20220160320
    Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an X-ray tube, an X-ray variable diaphragm, an X-ray detector, and processing circuitry. The X-ray tube irradiates X-rays. The X-ray variable diaphragm limits an irradiation region of the X-rays. The X-ray detector detects the X-rays that have passed through an object. The processing circuitry controls a movement of the X-ray tube, the X-ray detector, and an aperture of the X-ray variable diaphragm such that, when the irradiation region on the X-ray detector moves within an imaging range, a movement velocity of the irradiation region relative to the imaging range is maintained constant.

  • Patent number: 9195204
    Abstract: An image forming apparatus includes an image carrier, a toner-image forming unit, a transfer unit, a cleaner, a plurality of cylindrical transport path forming members, a falling transport path forming member, and a discharge port. The falling transport path forming member has through holes in a side wall thereof. A second end of each of the transport path forming members is inserted into a corresponding one of the through holes. The falling transport path forming member forms a falling transport path that causes toner ejected from an ejection port disposed in the second end to fall. The discharge port is disposed in a lower part of the falling transport path forming member to discharge the toner to a discharge destination. The second ends of the transport path forming members are disposed offset from each other in a horizontal direction on the side wall of the falling transport path forming member.

  • Patent number: 8913923
    Abstract: An image forming apparatus including an image bearing member, a charger, an irradiator, a developing device, a transfer device, a neutralizer, and a varying device is provided. The neutralizer is adapted to neutralize the image bearing member by emitting neutralization light thereto, after a toner image formed on the image bearing member is transferred therefrom. The varying device is adapted to vary an amount of the neutralization light to be emitted to the image bearing member by pulse-width modulation of a voltage to be supplied to the neutralizer. The image forming apparatus satisfies the following formula: f/V>5 wherein f (Hz) represents a frequency of the pulse-width modulation and V (mm/s) represents a linear speed of the image bearing member.
