  • Publication number: 20050051023
    Abstract: The present invention relates to a compress and position apparatus with positioning, orientating functions and providing more uniform pressing force compliantly. The compress and position apparatus comprises a guiding column, a base, a housing, a seat, a annular portion and a pressing plate. The base has a cylinder, a plurality of locating pins and a convex portion. The annular portion has a through hole and a plurality of locating holes. The guiding column and the cylinder are disposed in the housing provided with an opening for the guiding column passing therethrough. The housing is mounted on the base and passed through a through hole of the annular portion and disposed in a cavity of the seat. A plane on the housing abuts a plane on the cavity to prevent the rotation of the housing. The guiding column is combined with the seat. The locating pin is inserted into the locating hole. The pressing plate engages the annular portion. Thus the guiding column is moved up and down by the gas supply device.

  • Publication number: 20040203530
    Abstract: An energy saving type vibration device for cellular phone comprises a vibration member, a magnetic actuator, elastic means activated by the vibration member, and an electric coil. In response to an incoming call, a magnetic force of the electric coil is generated. The actuator is continuously attracted and repelled for moving back and forth respectively by the magnetic force of the electric coil as cyclic actions of charge and discharge of capacitors. The vibration member is thus capable of generating a resonance for causing the cellular phone to vibrate continuously, thereby informing a user of the incoming call.
