  • Patent number: 7777734
    Abstract: A liquid crystal displayer for preventing the generation of moisture includes a front cover, a touch panel, a nameplate, a partitioning plate and a liquid crystal displayer module. With the partitioning plate dividing a region between the touch panel and the liquid crystal displayer module into a first space and a second space, the first space is smaller, whereas the second space is larger. After the liquid crystal displayer module is supplied with electricity, the hot air staying in the first space is less. Further, the heat-obstructing effect of the partitioning plate causes the hot air not to condense in the second space, and thus it is not easy to generate a temperature difference from the external environment, thereby preventing the generation of mist.

  • Patent number: 6816748
    Abstract: The present invention proposes a smart automatic recording system and method for monitoring wafer fragmentation, which system comprises a plurality of photographing devices, a multiple-image transmitter, a multiple-image receiver, and a PC. The photographing devices are used to monitor the circumstances when wafers are polished. The photographed images are then transferred to the multiple-image receiver by the multiple-image transmitter. After the multiple-image receiver receives the image signals, it merges the images captured at the same time into the same image frame. Next, the multiple-image receiver transfers the image signal to the input terminal of an image-capturing card in the PC. The PC also receives the wafer-entry and wafer-exit signals and the signal of wafer fragmentation transferred from the port of the polishing apparatus. The present invention can be exploited to facilitate judgement, diagnosis, genuine factor verification, or engineering improvement and management for associated technicians.
