Abstract: An internal thread hole closing plug for closing an internal thread hole in a weld nut and a hole in a body panel includes a flange, column and elastic latching pieces and that extend from the column toward the flange and away from the column. The tips of the elastic latching pieces engage the thread flanks of the internal thread hole in correspondence with the lead angle of the threads thereof to align the axis of the column with the axis of the internal thread hole. The pair of lower elastic latching pieces extend in one radial direction, centered on the column, and the pair of upper elastic latching pieces extend in a radial direction that crosses the lower elastic latching pieces. This causes the axis of the column to be aligned with the axis of the internal thread hole when the column is passed through the internal thread hole.

Abstract: The present invention provides toner supplying devices, toner supplying processes, and the like that control bulk density of a mixture of toner and gas efficiently thereby enhancing the fluidity of the mixture, and maintaining the high fluidity for a long period. The invention includes a toner supplying device that has a toner containing portion configured to store a toner, a toner outlet configured to discharge the toner from the toner containing portion, a conveying pipe configured to convey the toner, and a gas feeding unit configured to feed a gas. The toner supplying device supplies the toner from the toner containing portion to an image forming unit of an image forming apparatus. A porous member is disposed near the toner outlet, and the gas is fed into the toner containing portion through the porous member.

Abstract: The object of the present invention is to provide toner supplying devices, toner supplying processes, and the like that control the bulk density of the mixture of toner and gas more efficiently thereby the fluidity of the mixture is enhanced, and the high fluidity may be maintained for a long period. The object is attained by a toner supplying device that comprises a toner containing portion configured to store a toner, a toner outlet configured to discharge the toner from the toner containing portion, a conveying pipe configured to convey the toner, and a gas feeding unit configured to feed a gas, wherein the toner supplying device supplies the toner from the toner containing portion to an image forming unit of an image forming apparatus, a porous member is disposed near the toner outlet, and the gas is fed into the toner containing portion through the porous member.

Abstract: A biaxially oriented laminate film comprising a wholly aromatic polyamide layer A and a wholly aromatic polyamide layer B containing an inert fine particles and laminated on one surface of the wholly aromatic polyamide layer A.The surface not in contact with the wholly aromatic polyamide layer B of the wholly aromatic polyamide layer A has projections having an average height of 2 to 85 nm and an average width of 20 to 500 .mu.m at a density of 4 to 2,500/mm.sup.2 and the surface, not in contact with the wholly aromatic polyamide layer A, of the wholly aromatic polyamide layer B is rougher than the surface, not in contact with the wholly aromatic polyamide layer B, of the wholly aromatic polyamide layer A.
