Abstract: PURPOSE: To efficiently form a fine pattern having fine line width and proper film thickness at high accuracy by forming a masking layer through a chromate treated surface on the surface of a substrate. CONSTITUTION: This master plate 1 for electrodeposition transfer consists of a substrate 2 at least the surface of which shows conductivity and a chromate- treated surface 4 formed into a specified pattern, and a masking layer 5 formed on the chromate-treated surface 4.

Moreover, when the masking layer 5 is formed on a recessed part, the contact area between the masking layer 5 and the substrate 2 is increased and the adhesion strength is further improved.  When the electrodeposition material precipitated in the area of the substrate 2 where the masking layer is not formed (the pattern for the conducting part) is transferred to a body to be processed, breaking of the masking layer 5 by an adhesive layer formed on the body to be processed or by other external force can be decreased.

Abstract: PURPOSE: To maintain the accuracy for pattern transfer by forming an adhesion improving layer for a conductivity film on an exposed part of the substrate surface of a stamper master 'disk. CONSTITUTION: A photosetting resin 2P not cured is dispensed on the surface of an original die and laminated with a glass substrate on which a replica material for pattern transfer and an adhesion improving layer 5 are formed. The laminated body is irradiated with UV rays to cure the resin 2P. Then the cured resin 2P on the substrate 1 is peeled from the original die to obtain the 2P replica 3 on the substrate 1.

Filed: 1986-10-29
Abstract: PURPOSE:To enable an ink sheet to be fed or taken up with a constant torque, by forming one of first and second friction members from a metallic material and forming the other from a fibrous material impregnated with an oil. CONSTITUTION:The feeding velocity and the tension of an ink sheet 1 are controlled by an ink sheet feeding reel 7a and the balance between a taking-up force of a take-up reel 7 and a load torque on a payout reel 2. A first friction plate 17 comprising a felt impregnated with an oil is provided on a side surface of a gear 16, whereas a second friction plate 18 made of stainless steel is provided on the periphery of a shaft 14. When motive power is transmitted from the gear 16 to an ink sheet roller 15 by the frictional resistance between the first and second friction plates 17, 18, the first friction plate 17 being flexible and elastic is brought into close contact with the second friction plate 18 in conformity with the shape of the plate 18, thereby stably transmitting the motive power from the gear 16. The oil in the felt functions as a lubricant, thereby securely causing slippage under a fixed torque and, therefore, preventing an excessive torque from being exerted on the roller 15.

Abstract: PURPOSE:To perform a stable focus control in the astigmatical method at the time of reproducing an FAD type SR disk. CONSTITUTION:The subject device is used for reproducing an optical disk (FAD type SR disk) formed of a material layer of lowering its reflectance when the temp. becomes more than a prescribed value on a transparent substrate forming phase pits. A main spot by 0th-order diffracted light L0 is formed on a read out track, while side spots by 1st-order diffracted light L1 on the adjacent tracks. The side spots have such light intensity that the reflectance in the side spots is not changed by a temp. change.

Reflected light of the side spots is incident upon a quadripartite detector 21 through a cylindrical lens 18, and from its output, an error signal Ef is generated to perform a focus servo by the astigmatical method. Because of no change of the reflectance in the side spots, the error signal Ef can stably be obtained, and hence the stable focus control can be carried out.

Filed: 1988-10-14
Abstract: PURPOSE:To improve processability for extrusion molding and mechanical strength by blending a resinous component including a copolymer of tetrafluoroethylene and alpha-olefine, and an ethylene-tetrafluoroethylene- fluoroolefine copolymer with an organic peroxide as well as a crosslinking assistant for a coating layer. CONSTITUTION:To form a coating layer, to 100 weight part of a resinous component including a copolymer of tetrafluoroethylene and alpha-olefin with 2 to 4 carbons, and an ethylene-tetrafluoroethylene-fluoroolefine copolymer, 0.01 to 0.5 weight part of an organic peroxide and a crosslinking assistant of 0.05 weight part or more are added. A crosslinked coating layer is also used. When the amount of the organic peroxide is less than 0.01 weight part, an extrusion characteristic is good, however, tensile strength and heat resistance are poor, and when it exceeds 0.5 weight part, crosslinking reaction is promoted for the poor extrusion characteristic. Extrusion molding is thus facilitated by the process, and an insulated wire covered with fluorine inclusive elastomer is obtained whose mechanical strength is improved to a great degree.
