Publication number: 20130032032Abstract: A filter device for filtering dust from air includes a housing, a dust collecting module, a spraying module, and an exhaust. The housing defines an air inlet near a bottom of the housing and an air outlet near a top of the housing. The dust collecting module is installed in the housing between the air inlet and the air outlet. The spraying module is placed in the housing between the dust collecting module and the air outlet. The exhaust is connected to the housing for generating air pressure difference between near the air outlet and near the air inlet, thereby drawing and introducing air containing dust from the bottom of the housing toward the top of the housing via the air inlet.Type: ApplicationFiled: December 5, 2011Publication date: February 7, 2013Applicant: FOXCONN TECHNOLOGY CO., LTD.Inventors: CHUN-CHUNG CHANG, WEN-HSIUNG CHANG, PING-NENG CHANG, RUN-CHENG LIN

Publication number: 20040090154Abstract: A parallelepiped lifting device mounted under a computer desk in a storage position is disclosed. Prior to using a computer, the device is activated by starting a motor in a clockwise rotation to lift an LCD of the computer from under the desk by means of a mechanism comprising chains, sprockets, and a bar. A lowering of the device into the desk is performed by starting the motor in a counterclockwise rotation by means of the same mechanism. The invention can save desk space for other purposes in the storage position.Type: ApplicationFiled: November 13, 2002Publication date: May 13, 2004Inventor: Chun-Chung Chang
