  • Patent number: 8093811
    Abstract: A technique for improving impact resistance performance of a panel is provided in a module or display apparatus with a flat display panel. In a PDP module, a filter is bonded onto a front surface side of a PDP, and a base chassis is bonded to a rear surface side with a two-sided tape. In an attaching portion for the base chassis and a casing, a spring structure portion having a sloped portion and a space is provided in an area of the base chassis so as to correspond to a connecting part of the casing. Impact to glass of the PDP is buffered to an impact force in a direction vertical to a surface of the PDP due to a spring property of the spring structure portion.
    Type: Grant

  • Patent number: 3954756
    Abstract: 2-Alkyl-4-amino-5-formylaminomethylpyrimidine is produced in a higher yield and using less process steps than the known methods by subjecting .beta.-aminopropionitrile to formylation in the presence of metal alcoholate, subjecting the resulting metal salt of .alpha.-formyl-.beta.-formylaminopropionitrile to alkylation or acylation, followed by allowing the thus produced .alpha.-alkoxy (or acyloxy)-methylene-.beta.-formylaminopropionitrile to react with an amidine.
