  • Stator mechanism of linear motor
    Patent number: 7944096
    Abstract: A stator mechanism of linear motor. The stator mechanism includes multiple magnetic members. The magnetic members are sequentially arranged along a predetermined straight line with the magnetic poles of the same polarity adjacent to each other to repel each other. Each magnetic member includes at least two magnetic bodies, which are coaxially arranged with the magnetic poles of different polarities adjacent to each other to attract each other.

  • Disassembling tool for air hose
    Publication number: 20100224037
    Abstract: A disassembling tool for an air hose is proposed. The tool has two pivotally connoted members. When drawn together, the two members jointly provide at least one air-hose hole that allows the air hose to pass through. By using the tool to press upon a joint of an air compressor, the air hose assembled in the air hose can be easily disassembled from the joint.
