Materials and Methods are provided for fabricating microfluidic devices. The materials include low surface energy fluoropolymer compositions having multiple cure functional groups. The materials can include multiple photocurable and/or thermal-curable functional groups such that laminate devices can be fabricated. The materials also substantially do not swell in the presence of hydrocarbon solvents.

A vacuum transfer apparatus including an auxiliary vacuum chamber and a main vacuum chamber is used for transferring an uneven pattern to a disk substrate with a stamper. The auxiliary vacuum chamber is vacuumized or opened to air because the disk substrate is conveyed to and from the vacuum transfer apparatus through the auxiliary vacuum chamber. The disk substrate conveyed to the auxiliary vacuum chamber and then to the main vacuum chamber after the auxiliary vacuum chamber is vacuumized. In the main vacuum chamber, transferring of the uneven pattern with the stamper, curing of UV-curable resin, and removal of the stamper are performed to provide a disk substrate with the uneven pattern. Then, the disk substrate is conveyed from the vacuum transfer apparatus through the auxiliary vacuum chamber. An operation at the auxiliary-vacuum-chamber side and an operation at the main-vacuum-chamber side are performed in parallel.

A disk structure is disposed in an optical tweezers device including a light source for producing incident laser light. The disk structure includes a first substrate, a second substrate and a reflective layer. The second substrate is disposed with respect to the first substrate. One of the first substrate and the second substrate has at least one flow path. The reflective layer, which is adhered to the second substrate, is disposed between the first substrate and the second substrate. After the incident laser light passes through the first substrate and then reaches the reflective layer, the incident laser light is reflected back as reflective laser light by the reflective layer to form reflective laser light. A tweezers light field is formed in the flow path by both the reflective laser light and the incident laser light.

In an optical disc, an information signal area on which an information signal can be recorded and/or reproduced is formed on a major surface of a disc substrate thereof; a light transmitting layer which can transmit a laser beam used in a process for recording and/or reproducing the information signal is formed on a side on which the information signal area is present; and a clamp reference plane is arranged on a major surface of the light transmitting layer in a clamp region. If the optical disc is clamped by a chucking unit of a drive, it is clamped by making the clamp reference plane on the major surface of the light transmitting layer contact with a mounting surface of a table for mounting the disc, and making a magnetic metal plate contact with the major surface of the disc substrate, and then sandwiching the optical disc between.

A compact disk (DVD) manufacturing machine is used to laminate first and second DVD substrates to produce a DVD, and mainly includes a glue applicator for applying a glue ring on a laminating surface of each DVD substrate; a DVD laminator for turning the first DVD substrate to the second one at predetermined speeds, allowing the glue rings to contact with each other before the two DVD substrates are slowly laminated; and a rotating element below a fixed sucker of the DVD laminator for rotating the laminated DVD substrates and ensuring even spread of the glue between the two substrates without producing blisters. Since the gluing and the laminating are synchronously performed at two different positions on a turntable of the machine, an increased productivity may be obtained.

An optical information recording medium is manufactured by bonding a first substrate having a first central bore and a second substrate having a second central bore to each other with radiation cure resin. The radiation cure resin is coated on the first substrate. The first and second substrates are brought into close contact with each other so as to form the first and second substrates integrally with the radiation cure resin. A neighborhood of the first and second central bores is radiated. A whole of at least one of opposite outer faces of the integral first and second substrates is irradiated with radiation so as to wholly cure the radiation cure resin.

There is provided an optical recording medium, in which a light transmitting layer is formed on a disc substrate, having less deflection and being excellent in recording/reproducing properties. In an optical disc, an information signal area on which an information signal can be recorded and/or reproduced is formed on a major surface of a disc substrate thereof; a light transmitting layer which can transmit a laser beam used in a process for recording and/or reproducing the information signal is formed on a side on which the information signal area is present; and a clamp reference plane is arranged on a major surface of the light transmitting layer in a clamp region. If the optical disc is clamped by a chucking unit of a drive, it is clamped by making the clamp reference plane on the major surface of the light transmitting layer contact with a mounting surface of a table for mounting the disc, and making a magnetic metal plate contact with the major surface of the disc substrate, and then sandwiching the optical disc between.

A process for manufacturing optical analysis discs with microfluidic structures and a disc made according thereto. The process includes the steps of providing a lens disc, patterning an intermediate adhesive layer with a pattern corresponding to predetermined microfluidic structures, providing a cover disc having molded microfluidic structures, and applying the cover disc onto the intermediate adhesive layer to match the molded microfluidic structures to the pattern to bond the cover disc onto the lens disc.

Adhering apparatus for plate shaped matter includes absorbing-and-holding means 10, 20 serving also as electrodes for absorbing and holding respectively first optical disc substrate 1 and second optical disc substrate 2, optical disc substrate moving means 40 for moving second optical disc substrate 2 to be approached to first optical disc substrate, distance detecting means 50 for detecting the distance between optical disc substrates, velocity controlling means 60 for controlling a relative velocity of the second plate shaped matter to the first plate shaped matter and controlling the plate shaped matter moving means in such a manner that the relative velocity immediately after and at a time point at which the adhesive applied onto the first plate shaped matter is brought in contact with the second plate shaped matter is slower than that immediately before the adhesive applied onto the first plate shaped matter is brought in contact with the second plate shaped matter; and voltage application means 71 for applying voltage between the first plate shaped matter and the second plate shaped matter before the adhesive applied onto the first plate shaped matter is brought in contact with the second plate shaped matter.
摘要:
An adhesive agent is applied to both single plates, upper and lower, in which case the formation of bubbles is minimized by using a specified application manner. A method of laminating optical disks (D) comprising the steps of placing a lower disk single sheet (D1) on a turntable (1), applying an adhesive agent (R1) in doughnut form to the lower disk single sheet (D1), placing an upper disk single sheet (D2) on another turntable (2), applying an adhesive agent (R2) in doughnut form to the upper disk single sheet (D2), placing the upper disk single sheet (D2) on the lower disk single sheet (D1), and spreading the adhesive agent (% 2) between the two disk single sheets by rotating the turntables. Since bubbles hardly enter the adhesive agent, the bubble content of the adhesive agent after spreading is very small, and even after the curing subsequent to ultraviolet ray radiation, the air content of the optical disk can be minimized, the quality being high.
