Abstract: A head-up display device projects display light from a display including a backlight unit and a liquid crystal display element on a viewpoint area of a viewer via projection means and causes an image by the display light to be visually recognized. The backlight unit includes: a light source emitting light for illuminating the liquid crystal display element; a lens array including a plurality of lenses, and dividing the light from the light source and generating a plurality of images of the light source; and light gathering means which gather the light from the images of the light source such that the light corresponds to a display area of the liquid crystal display element, wherein the lens array is configured such that the light distribution angles of the lenses at the periphery thereof are different from the light distribution angles of the lenses at the center thereof.

Abstract: Provided are: a backlight unit that is capable of increasing the degree of freedom in design of a device on which the backlight unit is mounted; and a display device which is provided with this backlight unit. This backlight unit is provided with: a light source which emits light that illuminates a liquid crystal display element; a light collection means for focusing the light emitted from the light source on a display region (A) of the liquid crystal display element; and a reflective part which has a reflective surface that reflects the light emitted from the light source toward the liquid crystal display element. This backlight unit is configured such that the optical path for the light from the light source to the liquid crystal display element is replicated at the reflective part by having the reflective surface inclined to the optical axis (AX) of the light source.

Abstract: The present invention is compact and inexpensive, has good light efficiency, and enables a display image having a plurality of display distances to be displayed. A display emits projection light for displaying a display image at a predetermined position, and an image formation position adjusting mirror receives the projection light emitted from the display, performs conversion into a plurality of first projection light and second projection light that have different image formation distances by changing the image formation distance of the projection light that is at least part of the incident projection light, and reflects the first projection light and the second projection light to project the first projection light and the second projection light onto a first screen and a second screen.

Abstract: The purpose of the present invention is to efficiently orient image light toward an observer. A display device outputs projection light for displaying an image. A transmission type screen forms an image of the projection light and diffuses the same as image light. A projection lens enlarges projection light and forms the image on the transmission type screen. A light distribution adjustment means is disposed between the transmission type screen and the projection lens and adjusts the light distribution of the image light output by the transmission type screen for each region by refracting the projection light.

Abstract: In a canister, an activated charcoal layer is placed in a fluid passage by which an air intake port is connected to a charge port or purge port, and a chamber dividing the charcoal layer into sections so as to traverse the fuel passage is defined by a grid and a filter pad placed on the surface of the grid. The grid has apertures uniformly formed on the surface of the grid contacting with the filter pad, so as to communicate with the chamber. Formation of the apertures on the surface of the grid prevents the filter pad from coming into the mesh of the grid, thus maintaining flatness of the filter pad.

Abstract: There is prevented reduction in volume of a chamber, by which an activated charcoal layer for a canister is divided into sections. [MEANS TO SOLVE THE SUBJECT] In a canister, an activated charcoal layer is placed in a fluid passage by which an air intake port is connected to a charge port or purge port, and a chamber dividing the charcoal layer into sections so as to traverse the fuel passage is defined by a grid and a filter pad placed on the surface of the grid. The grid has apertures uniformly formed on the surface of the grid contacting with the filter pad, so as to communicate with the chamber. Formation of the apertures on the surface of the grid prevents the filter pad from coming into the mesh of the grid, thus maintaining flatness of the filter pad. The original volume of the chamber can be maintained, so as to enable the fuel from the fuel tank to be absorbed effectively by the first and second layers of the charcoal layer, thus preventing the fuel from being released into the air.

Abstract: A molten metal supply device capable of supplying molten metal with high precision to an injection sleeve of a die-casting machine, and capable of reducing molten metal leakage and damage to a molten metal conduit bridging between a holding furnace and the injection sleeve. The holding furnace is divided into a holding chamber and a supply chamber in fluid connection with the injection sleeve through the conduit. Both chambers can be selectively brought into and out of fluid connection by a stopper. First and second immersion bodies are immersibly provided to the chambers, respectively. The laser sensor detects a predetermined level of the molten metal. The first immersion body is immersed until the sensor detects the surface of the molten metal, whereupon the stopper blocks fluid communication between the chambers. By then lowering the second immersion body, molten metal is pushed out of the supply chamber and a predetermined amount of molten metal is supplied to the injection sleeve.
