  • Publication number: 20180085082
    Abstract: An X-ray imaging apparatus comprises a distance detector 23, a distance calculation element 37 and a visible light source control element 33. The distance calculation element 37 calculates the distance from the visible light lamp 19 to the body surface of the subject based on the distance measured by the distance detector 23. The visible light source control element 33 controls a light intensity of a visible light emitted from the visible light source based on the calculated distance by the distance calculation element 37. The operator visually recognizes a brightness of the exposure field of the visual light, and can easily confirm that the visible light lamp has shifted to a suitable position for the X-ray imaging.

  • Publication number: 20170285534
    Abstract: An image forming apparatus includes an image forming unit, a transfer unit, and a controller. The transfer unit transfers a developer image formed by the image forming unit onto a transfer object. The controller controls each of the image forming unit and the transfer unit on a basis of printing data. The controller performs a printing control to cause a first printing operation and a second printing operation to be executed. The first printing operation forms a first developer image directed to an entire pixel region of a print image and transfers the first developer image onto the transfer object. The second printing operation forms a second developer image directed selectively to a high-gradation pixel region and transfers the second developer image onto the transfer object. The high-gradation pixel region is a pixel region, having a gradation value equal to or greater than a threshold, of the print image.

  • Patent number: 9592015
    Abstract: The disclosure provides a radiographic apparatus that allows suppression of needles radiation exposure to a subject. Specifically, the disclosure includes an X-ray tube, a collimator, and a visible light source. The spread of visible light beams through the collimator opening too largely may not possibly conform to the spread of radiation. Such a situation may occur when the apparatus is provided with the X-ray tube that emits narrow radiation. In order to avoid such a situation, the disclosure sets an upper limit of a degree of opening as an upper limit of a degree of opening of the collimator. With a construction of the disclosure, there is no need to perform further radiography. This achieves the radiographic apparatus that allows suppression of needless radiation exposure to a subject.

  • Patent number: 9411297
    Abstract: An image formation apparatus includes development devices placed in stations and configured to sequentially start development in an order according to the arrangement order of the stations, and a power supply unit. Each development device includes a development unit, a supply unit to supply a developer to the development unit, and a regulation member to regulate an amount of the developer on the development unit. The power supply unit applies voltages to each regulation member and each supply unit such that a first development device has a greater differential voltage when the first development device is placed in a first station than when placed in a second station in which the development is started earlier than in the first station, where the differential voltage denotes a voltage obtained by subtracting the absolute value of the supply unit's voltage from the absolute value of the regulation member's voltage.

  • Patent number: 8517839
    Abstract: An example game apparatus stores a state of a game during execution as execution state information in a memory, and stores a captured image of the game screen by bringing it into correspondence with the execution state information in the memory. Furthermore, during execution of the game, the captured image is displayed on a lower LCD while the game screen is displayed on an upper LCD. In a state that the game screen and the captured image are thus displayed, a selecting operation from a user is accepted. Then, by using the execution state information which is brought into correspondence with the captured image selected in response to a selecting operation, the state of the game is restored.

  • Patent number: 8515315
    Abstract: A developing device includes a developer bearing body, a first developer supply member, a second developer supply member, and a compression member. The developer bearing body bears a developer. The first developer supply member supplies the developer to the developer bearing body. The second developer supply member moves the developer in the vicinity of the first developer supply member to the first developer supply member. The compression member opposes, and is out of contact with, the first developer supply member. The compression member also directs the developer moved by the second developer supply member to the first developer supply member, and compresses the developer between the first developer supply member and the compression member.
