A method of manufacturing a spiral-wound PTFE gasket includes winding a laminated PTFE tape (300) around a shaft (305) that has an outer diameter that coincides with the gasket inner diameter to create a PTFE cylinder (315) having an outer diameter that coincides with the gasket outer diameter; sintering the PTFE cylinder (315); and removing a radial segment of the PTFE cylinder (315) to form the gasket (100), the radial segment having a thickness that coincides with the gasket thickness.

A spiral unit includes a base tube extended along a longitudinal axis and made of a first thermoplastic resin, and a fin disposed on an outer peripheral surface of the base tube along a fin axis spirally extended around the longitudinal axis and made of a second thermoplastic resin. The fin includes a strip portion provided in a state of being bonded to the outer peripheral surface of the base tube and spirally extended along the fin axis. The second resin being mixed with a magnetic material in the strip portion.

A high-pressure tank configured to store a fluid includes: a liner; and a fiber-reinforced resin layer configured to include a fiber and to cover surface of the liner. The liner includes: a cylindrical liner portion in a cylindrical shape; and dome liner portions in a dome shape connected with respective sides of the cylindrical liner portion, each dome liner portion being connected with the cylindrical liner portion, such that an outer surface of the dome liner portion is inclined at a predetermined angle to an outer surface of the cylindrical liner portion. The fiber-reinforced resin layer includes a hoop layer formed on the outer surface of the cylindrical liner portion to cover the outer surface of the cylindrical liner portion and provided by hoop winding that winds the fiber substantially perpendicularly to a central axis of the cylindrical liner portion. The hoop layer is formed, such that an outer surface of the hoop layer has a smaller angle than the predetermined angle to the outer surface of the dome liner portion at a boundary between the hoop layer and the dome liner portion.

A method for manufacturing an imprint mold which can prevent accumulation of the transferring resin onto the transferring roll is provided. According to the present invention, a method for manufacturing an imprint mold, including: a resin coating step to coat a photo-curing resin composition or a thermosetting resin composition onto a pattern transferring mold having a fine concave-convex pattern; and a transferring step to transfer the resin composition throughout the entire circumference of a cylindrical transferring roll and cure the resin composition so that a reverse pattern of the concave-convex pattern is formed throughout the entire circumference of the cylindrical transferring roll., is provided.

A method of manufacturing a fan case with a liner includes the steps of providing a preform having a circular cross-section with a cut and a first diameter, flexing the preform to reduce the first diameter to a second diameter, and adhering the preform to an inner surface of a fan case. A fan case for a gas turbine engine includes a fan case body having an inner surface. A preform is adhered to the inner surface and has a cut providing a gap.
