  • Publication number: 20120212550
    Abstract: An outgoing path port and a returning path port of a circulation path are at a position that is lower than a printing head. The outgoing path port and a discharge port of a discharge path are at a position that is lower than the returning path port. When ink droplets are ejected from the printing head, ink is pumped from a main tank to a sub tank using a supply pump, and ink is pumped from the outgoing path port to the printing head using a circulation pump with an opening and closing valve open and an opening and closing valve closed. In a case where discharge of ink in the sub tank and a circulation path is instructed before replacing of an ink unit, ink is pumped from the outgoing path port to a junction side using the circulation pump with both of the valves open.

  • Publication number: 20110175118
    Abstract: A method and optical component prevent external light reflection and increase light extraction efficiency. In one example embodiment, an optical component is provided on a light extraction side of a light-emitting panel. After a shielding film shaped like a lattice or a mesh is formed on a transparent substrate, a resist film is formed, the resist film is irradiated with ultraviolet light UV from the back side of the substrate by using the shielding film as a mask, and development is carried out, so that an optical functional element is formed. The planar shape of the undersurface of the optical functional element is the same as the planar shape of the lattice or the mesh of the shielding film, and a positioning error between the optical functional element and the shielding film becomes extremely small.

  • Patent number: 7913998
    Abstract: In a recording material guiding device, a second guide member is comprised of a hopper swinging surface, an edge guide member including a second side end guide member, and a liftup preventing guide. The hopper swinging surface is engaged in an opening provided in a side surface of a reference end guide serving as a first guide member. The second guide member can be slid in a main scanning direction with respect to the reference end guide (first guide member). During recording, a gap can be formed between the second side end guide member and a side end of the recording paper by sliding the second side end guide member from a first position to a second position, so that frictional contact can be prevented at the side end of the recording paper on the second side end guide member side.

  • Publication number: 20090262500
    Abstract: There are provided a cooling device and a heat sink that can effectively radiate heat generated by a heat source while reducing the volume of discharged gas to avoid noise, and an electronic apparatus in which the cooling device and the heat sink are mounted. A heat sink 3 includes cutouts 24a and 24b through which air serving as gas can be taken in from the outside and which are provided on a side where air discharged from first and second nozzles 6 and 7 serving as openings of a jet generating mechanism 2 is received. Therefore, the pressure near the cutouts is decreased by air flow discharged from the first and second nozzles 6 and 7, and outside air is taken in through the cutouts 24a and 24b. Consequently, more gas than gas discharged from the first and second nozzles 6 and 7 is discharged from an outlet of the heat sink. This can minimize the volume of jetted gas to avoid noise, and effectively radiate heat generated by a heat source.

  • Patent number: 7215630
    Abstract: The hinge (13) should preferably be formed to have a higher resistance than ever against the pivoting of the mirror body (12) to effectively prevent the hinge (13) from being damaged. By adopting a suitable one of a variety of production steps as necessary, the hinge (13) can be formed more finely and with a higher precision and thus the micro mirror unit can be produced more easily in a shorter time. To this end, the hinge (13) is formed from a different material, such as SiNx, from the mirror substrate material from which the frame (11) and mirror body (12) are formed.
