Abstract: A fixture for welding fabrication of a golf club head features a golf club head's hitting surface facing up and placed on a platform for a welding process so that a reverse side opposite to the welded hitting surface of the golf club head is held in a V-shaped groove on a fifth clamping part and the golf club head's peripheral surface contacts a first clamping part and a second clamping part; the golf club head can be held among the first clamping part, the second clamping part, a third clamping part driven by a first stroke unit to move toward the first clamping part, and a fourth clamping part driven by a second stroke unit to move toward the second clamping part; the hitting surface can be welded because of the golf club head free from movement toward the reverse side, which is opposite to the welded hitting surface, by means of the fifth clamping part.

Abstract: A roller microcontact printing device and a printing method of the device are revealed. The roller microcontact printing device includes a transfer module with a transfer roller and a supply module. The supply module provides an isolating solution and a thin film material to the transfer module to form an isolation layer and a thin film layer in turn on the surface of the transfer roller. Then the thin film is transferred to a substrate by the transfer roller. The microcontact print device and method are used in a roll-to-roll printing process. Thus the production efficiency of the thin film layer on the substrate is improved and the cost is reduced.

Abstract: A thickness adjustment device for thin-film coating is revealed. The thickness adjustment device for thin-film coating includes a coating device, a support set, and a thickness adjustment unit. The coating device consists of a work piece conveyor that delivers a work piece, and a material supply unit that carries a coating material onto a surface of the work piece to form a film. The support set is connected to the coating device while the thickness adjustment unit is inserted through and mounted on the support set. The thickness adjustment unit includes a scrape part disposed correspondingly to the work piece and used for applying coating material to form the film. The thickness of the film is adjusted according to a controlling force or torque of the thickness adjustment unit that presses downward. Thus the film is coated on the work piece evenly and the film coating quality is increased.

Abstract: This invention discloses a fabrication method of organic thin-film transistors (OTFTs) using the micro-contact printing. The OTFT can be of the bottom-gate or top-gate configuration. The micro-contact printing operation of this fabrication method does not require clean-room environment and high processing temperature, and does not have the problem of 2D shrinkage of the printed patterns either. Furthermore, the pre-wetting technique employed in the micro-contact printing results in improved fidelity in the pattern transfer and solves the problems of pairing and cross-talking between neighboring patterns.
