  • Patent number: 10478774
    Abstract: A denitrator removes nitrogen oxide in a flue gas generated from a combustion furnace by injecting a reducing agent into the flue gas. The denitrator includes a housing disposed above the combustion furnace. The housing includes a discharge port for the flue gas at one end of the housing. A cross-sectional area of flow of the flue gas gradually increases toward the discharge port. The housing gathers and guides the flue gas to the discharge port. The denitrator injects the reducing agent in another end of the housing.

  • Patent number: 10418615
    Abstract: A battery terminal includes a fastening portion (11) that is partially open in a circumferential direction and a flange (42) projects radially out from the fastening portion (11). Two facing portions (14) project radially out from open ends (13) of the fastening portion (11) and face each other in the circumferential direction. The fastening portion (11) is reduced in diameter and fastened to a battery post P by having the facing portions (14) approach each other. The flange (42) of the fastening portion (11) has cuts (20) for partially reducing a thickness of the fastening portion (11) in a radial direction.

  • Patent number: 9354708
    Abstract: While an information display device is initially placed at a standstill, a CPU stores acceleration responsive to gravitational force acquired by an acceleration sensor into a RAM. The CPU acquires acceleration in compliance with fixed timing acquired by the acceleration sensor and resulting from motion on the information display device. The CPU accumulates the acceleration acquired in compliance with the fixed timing within each prescribed period. Then, the CPU makes the accumulated acceleration agree with acceleration responsive to gravitational force stored in the RAM, thereby correcting a posture parameter. Based on the corrected posture parameter, the CPU determines whether a temporal image is to be displayed on a display unit.

  • Patent number: 9336626
    Abstract: An imaging apparatus generates a 3D model using a photographed image of a subject and generates a 3D image based on the 3D model. When a corresponding point corresponding to a point forming the 3D model does not form a 3D model generated using a photographed image photographed at a different photographing position, the imaging apparatus determines that the point is noise, and removes the point determined as noise from the 3D model. The imaging apparatus generates a 3D image based on the 3D model from which the point determined as noise is removed.

  • Patent number: 9201498
    Abstract: The matching processor acquires the key information such as position information and/or the like by the key information acquirer, and notifies to an external apparatus via the communicator. The matching processor stores the acquired key information in the storer corresponding to the identification information which is acquired from the external apparatus. When the acquired identification information does not exist in a AR data management table, the matching processor acquires the AR data by notifying the identification information to the external apparatus. When there is no empty record in a key information management table, key information of which usage date and time is old is considered as a deletion target. Moreover, when there is no empty record in the AR data management table, the AR data of which usage date and time is old is considered as the deletion target.

  • Patent number: 9058686
    Abstract: The utility of a service using AR is improved. The information display apparatus which applies an information display according to augmented reality (AR) acquires a reference image for matching with a subject in a captured image and scale information which shows a scale of the subject in the reference image from an information provision apparatus. Then, an inputter-outputter of the information display apparatus displays the captured image as well as a distribution of the reference images by a scale of the subject. On this distribution display, a guide display according to the scale of the subject in the captured image is performed. This guide display moves on the distribution display corresponding to a change of an angle of view. Accordingly, it is easily set the angle of view by which the matching using the acquired reference image can be performed appropriately, and the convenience improves.
