  • Publication number: 20200233296
    Abstract: A projection video display apparatus includes: a video projection screen, having a front and a rear surface, arranged in an indoor space. The video projection screen transmits video light from behind the rear surface or in front of the front surface to display video on the front surface. The front surface functions as a video display surface. A video projecting apparatus, arranged in a side of the rear surface or the front surface, enlarges and projects the video light from the rear or front surface. The video projecting apparatus is configured by an optical scanning video projecting apparatus that forms the video by scanning video light composed of coherent light on the video projection screen. The video projection screen guides the video light from the video projecting apparatus toward a direction to the front surface, and causes part of the light in the indoor space to be transmitted therethrough.

  • Patent number: 10556297
    Abstract: The present invention relates to a welded section examining device. In order to examine whether welding is good or bad of a welded section joining tip portions of electrical conductors projecting from slots of a stator core, a welded section examining device includes a camera, a discriminating unit, a wavelength-converting sheet, and a masking member. The camera images the welded section. The discriminating unit performs discrimination of whether welding is good or bad based on an outline of the welded section recognized from an image of the welded section imaged by the camera. The wavelength-converting sheet irradiates the welded section with a light, from a rear surface side of an imaging target surface. The masking member is interposed between the wavelength-converting sheet and the rear surface of the welded section, such that the outline of the welded section is imaged in the camera in an emphasized state.

  • Publication number: 20190334354
    Abstract: [Object] To achieve both prevention of overcharging of the battery and convenience of the user. [Solution] An information processing device includes: a charged capacity detection unit configured to detect a charged capacity of a battery; a charging control unit configured to control a charging circuit; and a specification unit configured to specify when discharge of the battery starts. The charging control unit performs charging suppression control on the charging circuit such that the battery is charged to a preparatorily charged capacity that is lower than a fully charged capacity of the battery, on the basis of the charged capacity detected by the charged capacity detection unit, the charging of the battery stops when the charged capacity of the battery reaches the preparatorily charged capacity, and the charging of the battery restarts from the preparatorily charged capacity before discharge of the battery starts.
