Abstract: A bicycle lining wear indication system includes a lining and a display device. The lining includes a back pate, a friction portion and a detection device. The detection device includes a detecting unit, an operation unit and a transmitting unit. The detecting unit detects a wear state of the friction portion after the friction portion contacts and rubs the disk of a wheel to produce a friction coefficient characteristic. The operation unit proceeds an operation on the friction coefficient characteristic to convert the friction coefficient characteristic into a digital value. The transmitting unit transmits the digital value to the display device to remind a rider of a wear extent of the friction portion. Thus, the detection device monitors and detects the wear extent of the friction portion so that the rider can replace the lining when the friction portion is worn out.

Abstract: A mechanical disk brake is disclosed, including a cylinder body, a brake pad, a piston, a cam disc and balls, where the structure design is as follows: cylinder body being provided with positioning gouges, the cam disc having a multi-section trench, and the balls being located between the positioning gouges and the multi-section trench, which enables the cam disc to be controlled for rotation which abuts against the piston and in turn to press against the brake pad for engaging a brake. The ball moves in the multi-section trench, which enables the cam disc to feature multiple axial displacements, thus to provide multiple sectional braking effect. This invention not only avoids the prior deadlock of the brake, but offers multiple segments of gradual braking effect, which offers the user multiple segments of tactual sensation.

Abstract: A base structure for a heat sink comprises: a heat conducting plate, a positioning piece, a plurality of legs and fasteners. The heat conducting plate is assembled together with the heat conducting plate to form two opposite guiding channels. The legs are positioned in the guiding channel by the fasteners. The fasteners are movable along the guiding channel along with the legs, and the legs are rotatable around the corresponding fastener, so that the positions of the legs are adjustable. Furthermore, the guiding channels is formed by the concave portion of the heat conducting plate and the groove of the positioning piece, and the heat conducting plate and the positioning piece can be produced separately, thus making it easier to produce the guiding channel.
