IPC: G06T17/05
Filed: 2002-09-20
Abstract: <P>PROBLEM TO BE SOLVED: To generate a three-dimensional map which is as realistic as to be used for a city planning.  <P>SOLUTION: The virtual three-dimensional map generation system is composed of a generation server 100 and a client CL. The generation server 100 generates a three-dimensional map three-dimensionally expressing buildings or the like in a virtual space. The three-dimensional map is generated on the basis of a two-dimensional map data base which defines the ground frame in which a building or the like is built. Such generating conditions to be satisfied when a building is built as regulations on the basis of the Building Standard Law and the Fire Protection Law or the like are set at every ground frame. The generation server 100 generates the three-dimensional map by arranging a prepared three-dimensional basic model and generating a columnar model by giving a height in the two-dimensional building frame to satisfy the generated conditions. A realistic three-dimensional map based on such regulations as the Building Standard Law is easily generated by taking the generating conditions into consideration.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To remarkably improve the separation resistance of a segment piece by inhibiting the oil pressure generated on an outer peripheral part.  <P>SOLUTION: Three kinds of segment type friction materials 1 are prepared by changing a ratio of an outer peripheral opening part a and an inner peripheral opening part b by changing round shape 5 sizes of an outer peripheral corner and an inner peripheral corner. For example, a first one has a ratio a/b=2.1, a second one has a ratio a/b=1.6, and a third one has a ratio a/b=1.0. As a result of the test of separation resistance, the separation is soon found, that is, only ten cycles in the duration test, on the friction material of a/b=1.0. On the contrary, the separation resistance is remarkably improved, that is, 500 duration cycles, on the segment type friction material having the outer peripheral opening part a larger than the inner peripheral opening part b by 1.6 times. Further the separation resistance is further improved, that is, 2,500 duration cycles, on the segment type friction material having the outer peripheral opening part a larger than the inner peripheral opening part b by 2.1 times.  <P>COPYRIGHT: (C)2004,JPO
