开发新型专利并在不同技术项目中运用这些专利的方向可通过下列方式进行分析:绘图处理专利统计资料;绘制《技术方案目标一实现方法》表;从数量上评定发明对技术项目所达到的技术水平产生的影响,以及其他方法。通过对世界工业发达国家在特铸领域开发的新型专利的汇总,进行了专利统计研究。1988年,从所有生产铸件的方法(其中包括砂型生产铸件)来看,这些国家共公布了4015项新型专利。
The direction of the development of new patents and the use of these patents in different technology projects can be analyzed in the following ways: Graphing and processing of patent statistics; Mapping the table of methods for achieving the objectives of a technical solution; Formulating a quantitative assessment of the technology The impact of levels, and other ways. Through the compilation of new patents developed by the industrialized countries in the world in the field of special casting, a patent statistics study was conducted. In 1988, from all the methods of producing castings, including the production of sand castings, a total of 4,015 new patents were announced in these countries.
