摘要:
A placement position of a sketched image into a three-dimensional space and viewing point direction are determined using the angle method or the three-point method, and the cross-section lines of a door cross-section line and center cross-section line of a vehicle depicted in the sketched image is determined and, based on the obtained cross-section line and center cross-section line, a spatial curved surface of the vehicle in the three-dimensional space is determined, distortion is corrected, and a curved surface is created.
摘要:
A three-dimensional shape data creating method associates characteristic points and characteristic axes on an image of a sketch drawn by a designer, or the like, with given points and given axes in a vehicle specs box, and determines the placement position and viewpoint direction of the sketch in a three-dimensional space by selecting combinations (point and point, axis and axis, and point and axis) having the minimum error in correspondence. Then, complex surfaces of given regions depicted in the sketch are created at a time in the three-dimensional space, by forming each cross-section line in a given region depicted in the sketch from a basic line and a fillet joint line, and a fillet joint surface is created between adjacent ones of the created complex surfaces of the given regions so as to join the complex surfaces.

A color graphic display device for providing a color image of an object, including three data memories, a device for preparing display data according to the data stored in the memories, and a color graphic display for providing or displaying the color image of the object according to the display data. The first data memory stores profile data associated with a profile of the object, and the second data memory stores incident-radiation data associated with a spectral distribution of a radiation to be incident upon a surface of the object. The third data memory stores reflection-characteristic data associated with spectral reflection characteristics of the surface of the object.

A method of producing clad steel plate comprises the steps of preparing an assembly slab by superposing a stainless-steel or nickel alloy cladding material onto base metal consisting essentially of, by weight, 0.020 to 0.06% carbon, 0.5% or less silicon, 1.0 to 1.8% manganese, 0.03% or less phosphorus, 0.005% or less sulfur, 0.08 to 0.15% niobium, 0.005 to 0.03% titanium, 0.05% or less aluminum, 0.002 to 0.006% nitrogen, and one or two elements selected from among a group consisting of 0.05 to 1.0% nickel, 0.05 to 1.0% copper, 0.05 to 0.5% chromium, 0.05 to 0.3% molybdenum and 0.001 to 0.005% calcium, with the balance being iron and unavoidable impurities, and welding its periphery; heating the slab to 1100.degree. to 1250.degree. C.; rolling the slab at a reduction ratio of 5 or more and a rolling finish temperature of 900.degree. to 1050.degree. C.; air cooling for 60 to 200 seconds; cooling the slab from a temperature of at least 750.degree. C. to 555.degree. C. or below at a cooling rate of 5.degree. to 40.degree. C./sec, and following this by air cooling.

A wire for gas metal arc welding containing 0.01 to 0.06 wt % of C, 0.10 to 0.60 wt % of Si, 0.9 to 3.1 wt % of Mn, 0.7 to 2.0 wt % of Cr, 0.005 to 0.06% of Ti, not greater than 0.08 wt % of Al and if necessary, 0.05 to 0.30 wt % of Cu, and the balance of Fe and unavoidable impurities. This wire improves the selective corrosion resistance and the low temperature toughness of the resulting weld metal, and is particularly suitable for circumferential welding of line pipes for transporting CO.sub.2 -containing petroleum, natural gases or CO.sub.2.

A bus bar for power supply is comprised of a pipe-shaped outer conductor and at least one inner conductor inserted therein. The inner conductor is also formed in a pipe shape and serves as a coolant flow passage. Insulation is interposed between the outer conductor and the inner conductor to electrically isolate them from each other.
