Abstract: A method for manufacturing an optical disc and a method for transporting a multi-layered optical disc are provided. When adhering the sheet and the disc substrate, after the adhesive is supplied to the outer side of the groove on the disc substrate, the sheet is loaded on the disc substrate. The adhesive is pressed to extend to the groove. At this timer, because the surplus adhesive is blocked when flowing into the groove, the surplus adhesive does not overflow easily toward the inner side of the groove. In addition, even if the adhesive overflows toward the inner side of the groove the adhesive is kept between the non-adhered portion of the sheet and the disc substrate, preventing the adhesive from moving to the disc surface. The non-adhered portion is cut by the cutting blade after the adhesive is completely cured, and then removed from the disc substrate.

Removal of bubbles is efficiently performed since semi-hardening and degassing are simultaneously performed. Further, no defective product is produced even if a working process is stopped since no process for semi-hardening a discharged adhesive exists.

Abstract: A filter device made of less expensive material than comparable filter devices heretofore has basic filter components plus some unique design aspects and an additional ring component. The ring provides an interface inside the filter which enables the potting compound to adhere to the filter and create a seal between a first and second fluid compartment within the filter. An embedded region of the ring possesses a detailed geometry which helps ensure that a delamination would be localized and unable to propagate from the first to the second compartment, maintaining the structural integrity of the filter device. To ensure that the sealing interface remains intact and free from delamination, the ring is subjected to a surface treatment, which modifies the surface energy of the ring. This modified surface energy of the ring allows the hydrophilic potting compound to more effectively bond to the modified hydrophobic ring.
