摘要:
There is provided an optical recording medium-manufacturing apparatus that is capable of avoiding breakage of a substrate while avoiding formation of a central hole off-center with respect to the substrate. A control section causes the vertical movement section to move an ultrasonic horn in directions toward and away from the cutting edge of a punching blade section to thereby cause the ultrasonic horn to press the disk-shaped substrate and at the same cause an ultrasonic generator to perform ultrasonic vibration at least from a time point at which the disk-shaped substrate is brought into contact with the cutting edge of the punching blade section to a time point at which the punching of the central hole is completed.

An optical recording medium-manufacturing apparatus which is capable of reducing wear of a cut-forming blade section used for forming a cut in a resin layer, without increasing the component costs of the apparatus. An ultrasonic horn includes a hollow-cylindrical cut-forming blade section for being pushed into a resin layer formed on one side of a disk-shaped substrate, thereby forming a circular cut in the resin layer. A control section controls motion of the ultrasonic horn caused by a moving mechanism. The control section causes the ultrasonic horn to be pushed in to the resin layer while causing ultrasonic vibration thereof to thereby form the cut, and while maintaining a state of ultrasonic vibration of the abutment section and a pushed-in state of the cut-forming blade section, causes the punching blade section to be pushed into the disk-shaped substrate, to form the central hole.

There is provided an optical recording medium-manufacturing apparatus that is capable of accurately transferring a disk-shaped apparatus during a manufacturing process, and at the same time occupies a small installation area. A control section causes a cut-forming machine installed at a cut-forming location to form a cut in a resin layer of a disk-shaped substrate, then causes an indexing mechanism to rotate a transfer stage to thereby transfer the disk-shaped substrate formed with the cut to a central hole-forming location, and then causes a punching machine to punch a central hole.

An applied film forming apparatus that forms an applied film on one surface of a substrate includes a dripping unit that drips an energy beam-curing applied material onto the one surface of the substrate, a rotating unit that rotates the substrate, a curing processing unit that emits an energy beam onto the applied material to cure the applied material, an emission regulating unit that regulates emission of the energy beam onto the applied material on an outer circumferential edge part of the one surface of the substrate, and a control unit. After controlling the dripping unit to drip the applied material onto the one surface and controlling the rotating unit to rotate the substrate and spread the applied material, the control unit controls the rotating unit to rotate the substrate at a predetermined rotational velocity, controls the curing processing unit to emit the energy beam toward the one surface, and additionally controls the emission regulating unit to regulate the emission of the energy beam onto the applied material on the outer circumferential edge part of the one surface of the substrate.

When manufacturing an optical recording medium by forming a resin layer on a surface of a substrate and then forming a center hole that passes through the substrate and the resin layer, a method of manufacturing an optical recording medium according to the present invention forms the center hole by forming, in the resin layer, a circular cut with a larger diameter than the center hole so as to surround a formation position of the center hole and then pressing in a punching blade for forming the center hole from a rear surface side of the substrate. By doing so, detachment of the resin layer and the production of burrs at or near the center hole can be avoided while reducing the manufacturing cost.

An object is to stick an artificial fingerprint liquid on a test sample in a constant condition. An artificial fingerprint stamping apparatus 1 operates such that as an arm 10 lowers, the self weight of a stamp unit 3 causes an artificial fingerprint transfer member 9 at the lower end of a stamp pin 6 attached to the arm 10 via a ball bush 11 to be pressed against an artificial fingerprint liquid transfer disk D1 for a predefined period of time, and thus an artificial fingerprint liquid is transferred onto the lower end surface of the artificial fingerprint transfer member 9. Then, after the artificial fingerprint transfer member 9 is positioned above a test disc D1, the arm 10 is lowered so that the self weight of the stamp unit 3 causes the artificial fingerprint transfer member 9 to be pressed against the test disc D1 for a predefined period of time.

An electron beam irradiation apparatus and method capable of easily curing at least part of a surface layer and/or a resin layer composed of materials that are hard to be cured by irradiation of ultraviolet rays. A disc-shaped object manufacturing apparatus and method capable of efficiently forming, on the disc-shaped object, at least part of a surface layer and/or a resin layer such as light transmitting layer, etc, thereunder. An electron beam irradiation apparatus comprises a rotary driving unit for rotationally driving an object, a shield container rotatably accommodating the object, and an electron beam irradiation unit provided in the shield container so that the surface of the object is irradiated with electron beams from an irradiation window thereof, wherein the surface of the object is irritated with the electron beams during its rotation from the irradiation window of the election beam irradiation unit. The surface of the on-rotating object can be thereby irradiated with the electron beams having larger energy than the ultraviolet rays have.

An optical recording medium 10 comprises a disc body 11, a white ink layer 12 provided on the label side 11b of the disc body 11, and an ink receiving layer 13 provided on the surface 12a of the white ink layer 12. The mean roughness (Ra) of the surface 12a of the white ink layer 12 is set not greater than 0.2 μm. A step radially extended is left on the surface 13a of the ink receiving layer 13 and set not greater than 1.0 μm. As the mean roughness (Ra) of the surface 12a of the white ink layer 12 is not greater than 0.2 μm or as the step on the ink receiving layer 13 is not greater than 1.0 μm, high printing quality can be secured when printing is done with an ink-jet printer.
摘要:
The present invention makes it possible to strip off a stamper stuck on a resin layer for groove formation during the manufacture of an optical disc from the resin layer without imparting damage or the like to the stamper. The present invention achieves this object by having the steps of bringing about a state in which the stamper protrudes from a substrate by a predetermined width, rotating the substrate with the back surface of the disc-shaped substrate attracted and held, elevating rollers capable of rolling relative to a contacting surface contacting with the protruding portion simultaneously with the rotation, and continuously applying a force working in a direction to separate the protruding portion from the substrate in the circumferential direction of the stamper.
