摘要： According to one embodiment, an illumination device includes a light guide plate and a plurality of light sources. The light guide plate includes a light emitting surface. The plurality of light sources whose light emission luminance can be controlled individually, the light sources being configured to supply light from an edge portion of the light guide plate into the light guide plate. A luminance distribution of light injected from the light sources into the light guide plate and emitted from the light emitting surface is obtained by a function such that relative intensity relative to a DC component in a spatial frequency region is less than or equal to a first threshold in a spatial frequency region having a value of one or more. Source-to-source distance of the light sources is optimized by the luminance distribution of the light.

摘要： An automotive display system includes an image projection unit and an angle information acquisition unit. The image projection unit projects a light flux including an image including a display object toward one eye of an image viewer. The angle information acquisition unit acquires at least one of vehicle angle information and external environment angle information. The vehicle angle information relates to an angle of at least one of an attitude and a heading of a vehicle carrying the image viewer. The external environment angle information relates to an angle of a background object at a target position of the display object in a background of an external environment of the vehicle. The image projection unit changes an angle of the display object in the image based on at least one of the vehicle angle information and the external environment angle information acquired by the angle information acquisition unit.

摘要： An outer case has an opening portion and a power generation element is held in the outer case and has a positive electrode and negative electrode with a separator interposed. A cover member is joined to the opening portion and the cover member is welded to the outer case with a laser beam. An injection port is formed in the cover member. After an electrolyte has been injected via the injection port into the outer case, a sealing member is pressed in a hermetical way into the injection port and then blocked by a sealing cover welded to the cover member using the laser beam. Furthermore, a pressing member is provided between the power generation element and the inner surface of the cover member wherein one end of the pressing member is receded a predetermined dimension from the injection port.
