    • PROBLEM TO BE SOLVED: To efficiently produce a lifting plan by providing a means to unify a plurality of members based on body three-dimensional data and a means to effect lifting check by a tower crane based on the center of gravity of a unit. SOLUTION: A computer effects selection of an abbreviated name and a kind, input of a name, display and setting of a symbol, setting of a widening angle during display of a circular arc, selection of a kind and the length of a jig, input of a reference point and a coordinate of a direction point, and input of the distance of each crane. Unifying of lifting members is set. Further, the center of gravity of the unit is displayed on a screen. The working order of the units is set. A disassembling unit is picked up from a structure and displayed on a screen. Further, when a unit to be lifted is selected on a screen, the center of gravity of the unit is displayed and the weight of the unit and the maximum load of a crane are displayed and it is decided whether the unit is lifted. This constitution produces efficient lifting plant.

    • PROBLEM TO BE SOLVED: To obtain a grounding method which prevents the operation of an electronic apparatus from becoming unstable and which prevents a noise from being mixed with the output of the electronic apparatus, by a method wherein the grounding terminal of the electronic apparatus is connected to an electromagnetic shielding material in an electromagnetic shielding space whose circumference is covered. SOLUTION: An electromagnetic shielding material 2 is a conductive material, which is used to cover the circumference of a space in order to constitute an electromagnetic shielding room in a building 1. For example, in a studio or a computer room, the electromagnetic shielding room in constituted of the electromagnetic shielding material 2, in order to prevent radio waves from creeping from the outside and to prevent the radio waves from leaking to the outside. An electronic apparatus 3 is an AV apparatus, an information apparatus or the like installed inside the electromagnetic shielding room and its grounding terminal is connected to the electromagnetic shielding material 2 inside the electromagnetic shielding room. A dedicated grounding wire 4 is a cable, with which the grounding terminal of an installed apparatus whose grounding is required, is connected to an underground buried ground 5. It constitutes a dedicated grounding system installed in a general building.
