  • Patent number: 7503722
    Abstract: A positioning device for clipping apparatus includes a hollow body which has an open side on one side that holds a track portion and an anchor portion on another side. The body houses a sliding member having a clipping unit and a harness arm. The harness arm is connected to the track portion to form a displacement path of the sliding member. The clipping unit includes an upper clipping portion and a lower clipping portion. The upper clipping portion is driven by the sliding member to move close to the lower clipping portion. A linking means connects an elastic element to the anchor portion and the sliding member so that the elastic element can be stretched and retracted against the displacement path of the sliding member to provide a returning elastic force to the sliding member. Thereby the sliding member can be positioned rapidly on each displacement path.

  • Publication number: 20090026051
    Abstract: The present invention includes a wheel mounted onto an electronic device through a holding rack and turnable freely under an external force. The wheel has a click portion to generate signals that consists of concave and convex portions formed radially and equally spaced from one another. A signal generation means is provided including at least two legs and a conductive element located between the two legs having an elastic return force. The conductive element is moved to connect the two legs due to rotation of the click portion to generate instruction signals. A friction force is generated when the conductive element is connected to the click portion. A rotation resistant force is generated when the conductive element and the rotating click portion are connected. A composite force is formed by the force to generate rotation and the rotation resistant force. The composite force forms an inverse relationship with the weight of the wheel.

  • Publication number: 20090017214
    Abstract: A method for directly forming patterns on face membrane by vacuum absorption is to have foamed polyurethane (PU) injected on the surface of substratum cloth to form a face membrane. Then, the face membrane is heated at a preset temperature by a preheating box to be continuously kept in a softened condition before it is not thoroughly hardened. Subsequently, a roller having functions of vacuum absorption and cooling has its superficial patterns quickly pressed and absorbed on the heated face membrane by vacuum absorbing force, and simultaneously the patterns on the face membrane is quickly cooled off and fixed in shape by the roller, thus shortening a producing process, saving factory equipment, conforming to environmental conservation and economizing energy source.
