  • Publication number: 20100148390
    Abstract: The nonwoven fabric sheet of the present invention is characterized by a porosity in the range of 0.3 to 0.7 and an average pore size in the range of 0.5 ?m to 5.0 ?m. The nonwoven fabric sheet of the present invention preferably has a maximum pore size (?m)/average pore size (?m) ratio of 1.30 or lower. The nonwoven fabric sheet of the present invention is obtained by press-molding a nonwoven fabric at a temperature lower than the melting point of the thermoplastic resin which constitutes the nonwoven fabric sheet. According to the present invention, there is provided a nonwoven fabric sheet that has a high porosity, small uniform pore sizes and excellent productivity, which can suitably be used in various applications such as filters, light diffusing material, liquid absorber and heat insulating materials; and a method for producing the nonwoven fabric sheet.

  • Publication number: 20070210040
    Abstract: A laser welding apparatus and method reduce the effect of the fume resulting from a weld. An air injecting nozzle is installed at a laser processing head. The injecting direction of air from the air injecting nozzle is set such that the air flows across a laser beam irradiated from the laser processing head while the air flow avoids direct contact with the laser irradiating point on the work piece.

  • Patent number: 7150912
    Abstract: An inter-labium product capable of disintegration in water, fitted to the inter-labium part; and a surface-side sheet for inter-labium product that simultaneously realizes comfortability at wearing of the inter-labium product and capability of water disintegration such that the inter-labium product is disintegrated when thrown in flush water of water closet after use. The surface-side sheet for use in an inter-labium product fitted to the inter-labium part is comprised of hydrophilic fibers composed of single fibers and fibril fibers having fuzzes branched from the surface thereof, wherein at least some of the branched fuzzes link the single fibers and the fibril fibers to each other. Thus, not only can the wet tensile strength be increased but also inter-fibrous bonds are slowly decomposed in the presence of a large amount of water to thereby enable disposal of the inter-labium product in a flush toilet.

  • Patent number: 7019227
    Abstract: In a case where a left-hand push-button switch is ON, a second relay RL2 is electrically de-energized to open a normally close contact RL2-1 of the second relay RL2 so that a relay contact circuit RC is opened. If, in this state, a right-hand push-button switch is shifted to a second OFF state, a normally close contact R3-1 of the right-hand push-button switch is opened. Thus, a third relay RL3 is not electrically de-energized and a first and a second circuits are in cutoff until both the right-hand and the left-hand push-button switches are returned to a first OFF state.
