The method additionally includes pushing a proximal end of a mandrel into the opening formed in the wall of the catheter and rounding the sharp external edge of the opening formed in the wall of the catheter with a distal end of the mandrel. The method further includes maintaining the sharp internal edge formed between the opening and the internal surface of the catheter.

The surrounding walls (23) are provided with first and second pressing surfaces (28, 29) to be pressed by ejector pins (83).
Abstract: A vulcanization apparatus provided with a vulcanization vessel for vulcanizing a green tire and a suction line for sucking out gas from inside the vulcanization vessel after the vulcanization vessel has been opened. Accordingly, oily smoke generated when vulcanized rubber has been removed from a bladder and an inner wall of a mold can be more efficiently discharged than in cases in which gas inside a vulcanization vessel is sucked out and additional air is introduced into the vulcanization vessel only prior to opening the vulcanization vessel.
Abstract: A pattern forming method includes determining an amount of curable resin to be formed on a substrate, the curable resin having volatility, the amount of the curable resin being determined by a calculation considering volatile loss of the curable resin, the calculation being performed for each of a plurality of regions of the substrate, forming the curable resin having the determined amount on the substrate, the forming the curable resin being performed for each of the plurality of regions of the substrate, contacting the curable resin formed on the substrate with a template, the template including a pattern to be filled with the curable resin by the contacting, and curing the curable resin under a condition where the curable resin is in contact with the template.

Abstract: A bladder monitoring apparatus and method for monitoring an inflatable bladder during curing of composite material in an autoclave. The bladder may be wrapped with composite material and have an impermeable membrane sealed around the composite material. The method may include the steps of fluidly coupling a vacuum port of the impermeable membrane with a vacuum source and fluidly coupling a vent of the bladder with a first port of a flow meter located outward of the autoclave. A second port of the flow meter may also be fluidly coupled with atmosphere within the autoclave. The method may then include evacuating air from within the impermeable membrane. If a flow above a threshold flow is detected by the flow meter, the leak in the bladder may be located and repaired or a valve of the flow meter between the first and second ports may be closed.
