Abstract: An internal rotor type nail drive device of electric nail gun, comprising a nailing rod and an internal rotor type rotary actuator that can output a specific rotation angle and can drive the nailing rod to move downward for nailing. Specifically, the rotary actuator comprises a stator and a rotor arranged inside the stator, even groups of electromagnetic mutual action components are configured in pairs between the stator and the rotor, to generate a tangential force to drive the rotor to rotate for a specific rotation angle, and to drive the nailing rod to move for a nailing stroke. The nailing stroke can be determined by a specific rotation angle. Thus, through the above configuration of the rotary actuator, the structure of the electric nail gun can be simplified, and the kinetic energy for nailing can be increased.

Abstract: A method for manufacturing a golf ball having a multi-layered pattern is provided. Firstly, a semi-finished product of the golf ball is provided and includes a ball-shaped body and a base layer covering an outer surface of the ball-shaped body. Then, the semi-finished product of the golf ball is rotated at a predetermined rotation speed, and a color paint is applied to the semi-finished product of the golf ball by spraying from each of an upper position, a middle position, and a lower position. The multi-layered pattern includes an upper-layer pattern area, a mid-layer pattern area, and a lower-layer pattern area that are different in color from each other.

Abstract: A handrail means for a bed frame includes a handrail frame, a shield, a handrail fixing frame, and a swinging assembly. When the swinging assembly acts, the shield does not act yet so as to avoid from interfering with the swinging assembly. When the swinging assembly is oriented horizontally, the shield can be folded toward the inside of the handrail frame. When the swinging assembly achieves a predetermined point, the shield has completed its action. Therefore, during the action, the shield avoids the handrail means from contacting the ground, thereby smoothing the folding of the handrail means of the bed frame.
