Abstract: The purpose of the present invention is to make it possible to shorten the time required for a burr removal step and make it difficult for the burrs to detach from a sheet member in a step for removing the burrs together with the sheet member. For removal, by making the burrs to adhere to a pliable sheet member such as paper or nonwoven fabric that has been incorporated beforehand in the molding die and stripping the sheet member from the molding die, the burrs are removed together with the sheet member. The present invention is characterized in that in order to make it difficult for the burrs to detach from the sheet member during the stripping, a radiused shape with an arc-shaped cross-section is formed by the molding die on the areas surrounding the sections where the burrs adhere to the sheet member.

Abstract: A seal includes an annular mounting portion having an axial leg extending axially from the annular mounting portion toward the air side. A radial leg portion extends radially inward from an end of the axial leg. A lay down sealing lip extends radially inward and axially toward the oil side from an end of the radial leg portion. A dust lip extends from the end of the radial leg portion in a direction opposite the lay down sealing lip. When the oil side is under negative pressure and when the lay down sealing lip begins to lift radially off the shaft, there is a counterbalance force applied to the axial leg that is designed to be flexible enough that the oil side vacuum “rocks” the seal bringing the dust lip into contact with the shaft and blocking airflow.

Abstract: Disclosed is a method for producing a hollow fiber carbon membrane using a hollow fiber carbon membrane-forming material by means of a dry method or dry-wet method comprising a spinning step, a drying step, an infusibilization step, and a carbonization step as basic steps; wherein in the infusibilization step, heat treatment is performed at least two times at different temperatures, with the second temperature being higher than the first temperature. It is preferable that the second heat treatment is performed directly after the first treatment is performed, without once cooling to room temperature. The obtained hollow fiber carbon membrane has improved permeability, without reducing its separation coefficient.

The metal gasket is provided with a planate outer peripheral portion and a bead portion which is formed by rising up from an inner peripheral end portion of the outer peripheral portion, and is arranged so that the bead portion comes into contact with the one casing, and the outer peripheral portion comes into contact with the other casing. The bead portion elastically deforms so as to reduce its height and the outer peripheral portion elastically deforms on the basis of the elastic deformation of the bead portion, when the metal gasket is pinched by the pair of casings, and a leading end of the outer peripheral portion comes into contact with one casing at this time, whereby any gap in which salt water stays is not formed between one casing and the metal gasket.
