A protecting block is located at the opening of casing or inside the cover. The protecting block is made by a PU material, and is provided with a plurality of emplacing holes which are passed through thereon, for inserting an end of billiard cue, such that the protecting block can protect the billiard cues from being damaged or deformed.
Abstract:
A hand tool having an adjustable head with a joint lock mechanism. The joint lock mechanism comprises a first engaging device, a push button, a second engaging device, a first elastic device and a second elastic device. The push button is formed with a through hole and a first engaging portion. The second engaging device passes through the through hole and is disposed with a second engaging portion. When the first engaging portion engages the second engaging portion, the front end of the first engaging portion abuts the front end of the second engaging portion such that the second engaging device engages the first engaging device and is prevented from moving.

Abstract:
A sensing device including a base, a pillar, an arm, a sensing element and a driving module is provided. The base has a supporting surface suitable for supporting the object. The pillar is disposed on the supporting surface. The arm has two ends and a pivot portion between the two ends. The pivot position is pivoted to the pillar along an axis substantially parallel to the supporting surface. The sensing element is disposed on the arm and located between an end and the pivot portion. The sensing element is located between the base and the object. The driving module is disposed between the arm and the base. The driving module drives the arm to pivot relatively to the pillar along the axis, and the sensing element moves toward or away from the object as the arm is pivoted.
Abstract:
The present invention discloses a multi-level output signal converter, which is connected to an audio amplifier. The audio amplifier comprises a comparing/measuring device, an encoder and an output unit. The multi-level output signal converter comprises a timing processing unit and a multi-level converter. The timing processing unit is connected to the comparing/measuring device and the encoder. The timing processing unit includes a plurality of flip-flops and a timing summing element. The flip-flop receives a first signal from the comparing/measuring device and outputs the first signal to the timing summing element. The encoder converts the first signal into a second signal. The multi-level converter is connected to the encoder and the output unit. The encoder transmits the second signal to the multi-level converter, and the multi-level converter thus outputs a third signal to the output unit.
Abstract:
An exemplary liquid crystal display includes a first substrate; a second substrate opposite the first substrate; a liquid crystal layer interposed between the first and second substrates; a plurality of pixel electrodes disposed at the second substrate; a plurality of parallel first data lines alternately disposed at the second substrate; a plurality of parallel second data lines alternately disposed at the second substrate. Each of the first data lines is disposed upon and insulative to a corresponding second data line, and each of the first and second data lines provides signals to a corresponding pixel electrode.
Abstract:
An easily disassembling cooling apparatus is assembled onto a circuit board. The circuit board has an electronic element. The cooling apparatus includes a pair of fastening blocks, one or two heat conducting blocks, a heat pipe, a fastening plate, and a plurality of locking elements. The fastening blocks are fastened onto the circuit board and each has a track slot. The heat conducting block is installed between the fastening blocks and contacts the electronic element. One end of the heat pipe is installed with the heat conducting block. The fastening plate is installed in the track slots of the fastening blocks, and has a flexible arm that flexibly presses onto the heat pipe. Each of the locking elements respectively is combined with the fastening block. Thereby, the welding process is not required in the assembling process. The electronic element is reliably cooled, and the assembling time is reduced.
