  • Method and apparatus for detecting a lower level software reusable product in generating an upper level software product from a lower level software product and changing the upper level software product
    Patent number: 5590270
    Abstract: A reverse engineering method for supporting software reuse in generating an upper level software product from a lower level software product allowing the reuse of some software product's among multi-level software products ranging from an upper level data flow to a lower level job flow. The method includes the steps of: generating an upper level software product using a lower level software product; generating relational information between the lower and upper level software products; inputting a request for changing the upper level software product via an input/output interface; changing the upper level software product in response to the change request; and detecting a reusable field of the lower level software product which is not to be changed, in response to a change of the upper level software product.

  • Dentifrice composition
    Patent number: 4594242
    Abstract: A dentifrice composition comprising calcium hydrogenphosphate anhydride whose crystallite has an average size of 300 to 3,500 angstroms as measured by X-ray diffractometry and an aluminum oxide having an average particle size of 0.5 to 10 .mu.m is disclosed. The composition have an excellent cleaning ability and mild abrading property not causing damage of tooth enamel and gives good luster to teeth.
