Abstract: There are provided a first step of bending adjacent portions of first and second metal members in the same direction and forming a flange overlapping part where respective flange portions of the first and second metal members are overlapped and contact each other, a second step of starting to perform arc welding from a tip of the flange overlapping part, and a third step of continuing to perform the arc welding until molten metal of a core wire and a base material reaches an opposite-side face of the flange overlapping part and zinc gas generated is emitted from a side opposite to an arc-welding performance side of the flange overlapping part.

Abstract: A system for editing sheet metal components using a computer, comprising a sheet metal object having graphic element data defining the graphic elements of a sheet metal and connection data defining face data comprising graphic elements and linkage of the faces, wherein the sheet metal object includes a sheet metal edition object corresponding to editing of a sheet metal, e.g., editing of butting or lapping of sheets, and the burden is lessened by automating reformation at the butting or lapping part of the sheet metals.

Abstract: Data for a 3D sheet metal part model is stored in a file. The stored data includes features of the part and manufacturing information. When different manufacturing processes are used, different geometry can be created. The file can store multiple processes for manufacturing the part and the geometry associated with each process. Thus, when manufacturing the part, the user can view information for multiple stored processes because all of the information is stored together. In addition, both 2D and 3D data is stored for the part.

Abstract: Analysis is performed on sheet metal products to determine characteristics (or feature vectors) of the sheet metal products. Multiple feature vectors can be obtained for each sheet metal product. Exemplary analyses include a first order moment and a second order moment. The characteristics can be compared with characteristics of other sheet metal part shapes to determine how similar the shapes are.

Abstract: A method of editing an assembly with CAD includes selecting, through navigation, a first element of a first part among parts displayed on a CAD screen, the parts being made of sheet metal and being assembled into the assembly, the navigation automatically selecting an element of a part under a cursor as the cursor is moved on the CAD screen, dragging the first part including the first element with the cursor in one of horizontal and perpendicular directions relative to the first element, selecting, through navigation, a second element of a second part among the parts displayed on the CAD screen, and attaching the first element of the first part to the second element of the second part.

Abstract: An automatic programming apparatus wherein respective planes constituting a solid input from a two-dimensional three-side view drawing are displayed on a screen. When a reference plane and a butting plane are specified within the respective planes, a temporary development diagram is generated in which the butting plane is butted to the reference plane. A solid figure is generated by bending the temporary development diagram based on a bending condition and displayed interlockingly in a region different from a region where the temporary development diagram is displayed. A development diagram obtained by extracting external frame loop and bending lines of the temporary development diagram is transmitted to CAM on a preceding stage.

Abstract: A sheet metal working graphic data generation method includes displaying respective planes constituting a solid input based on two-dimensional three side views on a screen. The method also includes obtaining and displaying a temporary development diagram obtained by butting a butting plane with a reference plane when the reference plane and the butting plane are selectively specified from the respective planes. The method further includes generating a solid figure by bending the temporary development diagram according to the bending condition; and displaying a perspective view based on the solid figure interlockingly in a region different from the temporary development diagram on the screen.

Abstract: A liquid crystal display apparatus includes an active matrix substrate and a counter substrate opposing the active matrix substrate via a liquid crystal layer. The active matrix substrate includes: a display portion having a plurality of source lines, a plurality of gate lines crossing the plurality of source lines, a plurality of pixel electrodes arranged in a matrix in regions surrounded by the plurality of source lines and the plurality of gate lines, and switching elements for connecting the pixel electrodes to the source lines and the gate lines; and a first electrode provided along the source lines outside of the display portion, wherein the first electrode serves to produce a reference signal by changing a surface potential distribution of the substrate, and the positions of the plurality of pixel electrodes are determined based on the reference signal.

Abstract: In a pressure-controlling apparatus employed in a pre-chamber of an environmental testing chamber for a self-propelled vehicle, in which testing chamber various tests are conducted under a subatmospheric pressure, which testing chamber is provided with the pre-chamber for permitting an opertor's getting in/out of the testing chamber, the improvement resides in that: operational switch means provided in the pre-chamber permit the operator to open/close a first and a second opening/closing valves, which first opening/closing valve is provided in a first air-duct which opens into open air at one end and into said pre-chamber at the other end for recovering an air-pressure of the pre-chamber, which second opening/closing valve is provided in a second air-duct which opens into the testing chamber at one end and into the pre-chamber at the other end for reducing the air-pressure of the pre-chamber.

Abstract: A salt damage environmental testing chamber for self-propelled vehicles which is provided with a salt water spraying system, is disclosed. According to the present invention, a protective cover that may be opened and closed by a cover opening and closing device is provided in the vicinity of a humidty sensor provided in turn in the test chamber. The cover opening and closing device is actuated at the time of spraying of salt water into the test chamber to close the protective cover so that the humdity sensor is covered by the protective cover.
