Abstract: A multi-functional exercise device includes an upper part and a lower part. The upper part has a base. The base includes two side walls extending from two sides thereof, a grip member mounted between the two side walls, and an elastic engaging hook beneath the base. The lower part includes a support disc having a central engaging hole for the elastic engaging hook to be engaged therein, at least one mounting portion at a lower end of the support disc, and at least one rolling element mounted to the mounting portion. The elastic engaging hook of the upper part is engaged with the engaging hole of the lower part so that the upper part and the lower part are connected together. The upper part is applied with a force to drive the lower part to move along the direction of the applied force for the user to do exercises.

Abstract: A method for manufacturing a massage wear-resistant treadmill deck and a finished product thereof are provided. The method includes step 1: providing a mold, the mold having a plurality of cavities thereon, a wear-resistant material being injected into the cavities of the mold; step 2: placing a deck in the mold so that the wear-resistant material is bonded to a surface of the deck to form a plurality of massage protrusions on the deck; and step 3: demoulding the deck from the mold, the surface of the deck being formed with the massage protrusions to form the massage wear-resistant treadmill deck. A wear-resistant layer having the massage protrusions is first formed in the mold, and then the deck is placed into the mold to bond with the wear-resistant layer to form the massage wear-resistant treadmill deck. The manufacturing cost is reduced and the manufacturing mobility is improved.

Abstract: A treadmill having a curved treadmill deck is provided. Two curved side frames are disposed at two sides of the treadmill frame. Front and rear end ends of each curved side frame are higher than a middle section thereof. Inner sides of the two curved side frames are provided with a plurality of fixing seats, respectively. The fixing seats have fixing holes, respectively. An elastic deck is composed of a plurality of sheets connected side by side. The sheets each have perforations corresponding in position to the fixing holes of the respective fixing seats. A plurality of fixing pins are inserted in the perforations of the sheets of the elastic deck and secured to the fixing holes of the fixing seats. The elastic deck is forcibly fastened by the fixing pins and slightly deformed according to the curvature of the curved side frames to form the curved treadmill deck.

Abstract: A horse riding exercise machine is not only compact in structure but also easy to be assembled and disassembled. When in use, a second N-shaped connecting rod and/or a return member are provided to achieve a labor-saving effect for exercise. Through a compact structure and the detachable connection of a bolt, when the horse riding exercise machine is not used, the bolt can be loosened so that a rear support base can be pushed toward a front support base to close up, thereby reducing the storage space to facilitate the storage.

Abstract: In a method for creating a via in an IC manufacturing process, a substrate is provided and a circuitry structure is formed over the substrate. Then, a dielectric layer is formed over the circuitry structure; a hard mask is formed on and a trench is created through the dielectric layer; a coating layer is formed on the hard mask, filling the trench; an etch opening is defined in the coating layer by performing a pattern transfer process, wherein a width of the etch opening is greater than a width of the trench; and the bottom of the trench exposed from the etch opening is etched off with the hard mask, thereby creating a via for conductors.
