  • Publication number: 20110001277
    Abstract: There is provided a method of manufacturing a hollow structural member suitable for precisely manufacturing a hollow structural member whose pitch space of the hollows is below 30 ?m. The method of manufacturing a hollow structural member of this invention is to encapsulate, by using a gas-permeable material in part of a material that constitutes the substrate (5) for manufacturing the hollow structural member, a high-pressure gas by injection in advance, under high-pressure conditions, into the gas-permeable material; to form a plastic deformation film (10) on a surface under reduced-pressure conditions; and to expand and draw the plastic deformation film (10), while preventing the plastic deformation material from entering the recesses (5b), by discharging the high-pressure gas that is encapsulated in the gas-permeable material into each of the recesses (5b), whereby the hollow structural member is manufactured.

  • Publication number: 20090051735
    Abstract: A liquid droplet flight device is provided that moves an ink or the like using a comparatively low voltage and stably causes flight of even a high viscosity ink or the like. When causing droplets of a liquid inside a liquid retaining section to fly onto a medium transported between liquid droplet discharge means and an opposing electrode in the liquid droplet flight device, a high voltage is applied to the flight electrode from a bias power source to generate an electric field between the flight electrode and the opposing electrode. On/off control of flight control means is performed in this state to apply a drive voltage of a low voltage to an EW drive electrode from a drive power source such that the liquid inside a slit moves to a leading end portion of the flight electrode due to an electrowetting phenomenon, and the liquid that has moved to the leading end portion of the flight electrode flies toward the opposing electrode through the electric field such that a liquid droplet lands on the medium.

  • Patent number: 6791771
    Abstract: A composite optical component and its manufacturing method are disclosed. A holding member or an optical functional device is subjected to elastic deformation, with both of them fixed together, and the optical functional device is subjected to plastic deformation by heating to reduce stress between two components in such a way that the holding member and optical functional device will be slide-fitted with each other; sliding resistance between the optical functional device and enclosure per “b” in longitudinal direction of the optical component will be F≦a/b×S×E; or the optical functional device and holding member will be slide-fit by formation of one integral body in the mold, thereby preventing thermal distortion and distortion of the optical functional device due to recovery of elastic deformation of a reinforcing member, with the result that manufacturing costs can be reduced while a high degree of straightness and high surface precision are maintained.
