Abstract: A melt cutter includes a case, an electricity-connecting portion, a heating device, a working portion, a controlling portion, and a heat-dissipating device. The case has a heat-dissipating zone. The electricity-connecting portion is disposed in the case for connecting with an electricity source. The working portion is disposed in the case and has a gap with changeable size for clamping an object. The controlling portion alternatively triggers the heating device to heat and to transmit heat to the working portion, and it also reduces the size of the gap for melting and cutting the object. The heat-dissipating device is disposed at the heat-dissipating zone and is electrically connected with the electricity-connecting portion. Thereby, the heat-dissipating device helps air communication between interior and exterior of the case.

Abstract: A structure of valve stem and frame lining includes a frame lining, a valve body, and a stem. At least two ribs are formed on one face of the frame lining, and the other opposite face of the frame lining is engaged with a base portion of the valve body by molding. The stem is disposed in an air channel of the valve body to control availability of air through the air channel. More particularly, when being disposed on a wheel frame, the frame lining has a width which enables the frame lining to overlap an outer cover engaged with the wheel frame to provide good sealing performance. Besides, the ribs help the frame lining be positioned on the wheel frame.

Abstract: A cable sheath of the present invention includes several adapter tubes which can be joined to one another. Each of the adapter tubes has a metal outer tube and a plastic inner tube. The plastic inner tube which is inserted into the metal outer tube abuts against the metal outer tube, so that the plastic inner tube of each of the adapter tubes can be used for receiving a metal cable therein. Thereby, said invention can receive a brake cable or the like without a plastic tube of the cable, so that said invention can prevent the cable from being wound by a remaining interior stress from the plastic tube.

Abstract: The present invention provides a heat dissipation plate which includes a heat dissipator and two elastic plates. The heat dissipation plate is adapted to be disposed in a bicycle disc brake. The elastic plates are fixed to the heat dissipator, and the elastic plates are disposed in the bicycle disc brake so as to fix the back panels of the brake linings in the disc brake. Thereby, the elastic plates of the present invention can conduct the heat, which is generated when braking, to the heat dissipator, so that it can prevent the brake linings from overheating when braking. The overheated brake linings may make the disc brake fail to stop the bicycle; therefore, the present invention can enhance the safety of the bicycle disc brake.

Abstract: The present invention is to provide a tube for cable sheath and the cable sheath using the same. The front end of each tube is connected to the rear end of another one. Two side plates are connected to another tube. A cable is received in the cable sheath. Thereby, when a brake cable is received in the cable sheath, the side plates are connected to another tube so as to restrict one of the bending direction degree of the cable that can avoid the cable sheath being bended in all direction. It is important that the side plates can protect the connecting point of each tube quite well and enhance the structure intensity of the whole cable sheath. After standardizing the specification of the present invention, it can be connected to many kinds of products. The present invention has abundant variability and achieves the best efficacy.

Abstract: The twisted cable is produced by entwisting plural surround wires together on a central wire. The surround wires have several different sizes. The surround wires are arranged in a particular arrangement so as to reduce elongation when stretch force is exerted on the twisted cable. In addition, the outer surround wires have smoothened outer surfaces, so that the twisted cable has smooth and satiny outer surface. Friction and abrasion caused by pulling the twisted cable is reduced.

Abstract: A brake cable sheath for bicycle of the present invention includes a plurality of tubes. The tubes can be serial arranged for a brake cable to be received therein. Each tube is formed with two fixation holes and two slots. Each slot communicates radially with one of the fixation holes, so that wires may be received in the fixation holes via the slots. As such, the tubes of the brake cable sheath can be assembled and engaged with wires. The brake cable sheath can be sustained stably to reduce shaking.
