  • Publication number: 20160349909
    Abstract: A portable electronic device includes a first body and a second body. The second body includes a processing unit, and a first touch panel, a second touch panel, a keyboard and at least one detecting module electrically connected to the processing unit, respectively. The keyboard is slidably disposed above the second touch panel, and the detecting module is adapted to detect a position of the keyboard. When the keyboard is located at a first position, the keyboard module covers the second touch panel, and the detecting module transmits a first signal to the processing unit so that the first touch panel is turned on. When the keyboard is located at a second position, the keyboard exposes the second touch panel, and the detecting module transmits a second signal to the processing unit so that the first touch panel is turned off. A touch panel controlling method of the portable electronic device is further provided.

  • Publication number: 20160272755
    Abstract: A polyester polymer and a method for manufacturing the same are revealed. Sulfonate groups (—SO3) are used for modification of polyethylene terephthalate (PET) and chemical extrusion technique is used in modification processes. The physiochemical properties of PET sulfonate obtained including moisture absorption, secondary transition temperature, melting point etc. are improved significantly. Thus the dyeing process can be carried out at lower temperature and the dyeing depth is improved. The purpose of energy saving and reduced carbon dioxide emission are further achieved.

  • Publication number: 20150075426
    Abstract: The present invention relates to a pulsed laser deposition system, and particularly relates to a pulsed laser deposition system capable of using several different targets. In the pulsed laser deposition system, a beam-splitting device is provided to split a UV laser beam into several UV laser beams and to introduce these UV laser beams to different targets simultaneously. Therefore, the pulsed laser deposition system can use several different targets and can be used to form doped epitaxial layer (III-V semiconductor film) and ternary or quaternary epitaxial layer (III-V semiconductor film).
