Abstract: PROBLEM TO BE SOLVED: To appropriately remove dust at the time of manufacturing a disk cartridge. SOLUTION: In this manufacturing method of the disk cartridge for which a disk-like record medium and a cartridge case 2 at least partially composed of a thermoplastic material for rotatably housing the disk-like record medium are provided and the cartridge case 2 is formed by the ultrasonic welding connection of an upper half 2a and a lower half 2b, the dust is removed at the time of ultrasonic welding the upper and lower halves 2a and 2b.

Abstract: PURPOSE:To provide the unit for making the fibers flame-resistant or infusibilization which can increase the infusibilization rate without giving any physical damage to the precursor fibers. CONSTITUTION:In the infusibliization unit where two groups of outer rollers 12a through 12c and 13a through 13c are arranged on both sides of the infusibilization furnace 20 in the longitudinal direction so that the precursor fibers 101 can be passed through and returned several times, and solid thermal medium particles 30 piled up in the furnace 20 are fluidized with a heated oxidative gas to effect continuous heat treatment of the precursor fibers 101 in the fluidized thermal medium, at least one of a porous body 31 of wavy cross section is set between each stage of the yarn path. On the way the bubbles in the fluidized layer 4 go up, they collide to the porous body 31 to change their vectors and the bubbles burst into uniform fine bubbles.

Abstract: PROBLEM TO BE SOLVED: To prevent spring placement failure from occurring by providing a height difference between a member end face part for guiding a spring edge to a cutting entrance and a member end face part at the opposite side, and making the cutting end engageable. SOLUTION: In a cartridge 12, a slider 11 is engaged and a shutter is placed, and since a member end face part 11b is higher than a member end face part 11a, a spring edge 6a is abutted to the side surface of the member end face part 11b to be engaged, thus preventing the spring edge 6a from being pushed in further and jumping over the entrance of a cutting 12. Since the jumping over the entrance of the cutting 12 is prevented, a spring 6 is engaged in a specific state surely, thus preventing the spring 6 from being placed improperly.
