摘要： In a forging process analyzing method, many trace points are set in a workpiece. Lines connecting the trace points express fiber flow lines. The fiber flow lines may be imaginary ones that are irrelevant to real fiber flow lines. By applying a technique of a finite element method to the fiber flow lines, deformation calculation is performed. A new trace point is added between trace points when the distance therebetween is great. The velocity of each trace point cause by deformation is calculated, and the position of each trace point is updated. When any trace point in an element is left behind in a die, the left-behind phenomenon is prevented by converting the shape of the element while the crossing of fiber flow lines is prevented. A radius is set for each trace point. The radius of each trace point is adjusted so as to eliminate off-boundary extension and overlap of fiber flow lines.

摘要： A semiconductor device includes a plurality of real chip regions and dicing lines to separate the real chip regions on a semiconductor substrate. A dicing line includes a mark section and a mark forbidden region around the mark section. A dummy wiring pattern is formed to fill the dicing line or a portion of the real chip region to surround the mark section and the mark forbidden region. A dummy wiring pattern may be a single continuous wiring pattern or the single wiring pattern may be divided into segments. Alternatively, a dummy wiring pattern may be composed of a plurality of square portions arranged in a matrix fashion.

摘要： An automatic seam welding apparatus for fuel tanks comprises a jig for holding two workpieces disposed one above the other to form a fuel tank, a pair of roller electrodes vertically arranged for nipping and welding the overlapping peripheral flange portion of the workpieces, and a robot assembly rotatably supporting the jig and controlling the horizontal and vertical positions and the inclination of the jig held workpieces relative to the electrodes for welding peripheral flange portions that are irregular with high quality welds. The jig is easily detachable from the robot to permit many different shaped tanks to be welded by the same apparatus.

摘要： A catalytic converter includes a tubular casing within which is held a monolithic catalyst body which is generally of a columnar shape. The ends of the monolithic catalyst body are each engaged with a cushion ring, and each cushion ring is engaged with a retainer ring therefor, which is substantially axially fixed within the casing near to an end thereof. The monolithic catalyst body is supported within the casing by axial compressive force present between the retainer rings on the outside, the cushion rings between the retainer rings, and the monolithic catalyst body between the cushion rings. At least one of the retainer rings is formed with a break in a part of its circumference, the two free ends of the retainer ring on the two sides of the break being movable with distortion of the retainer ring through a certain distance, according to changes of temperature of the retainer ring, with respect to one another in the mutual relative direction which causes the overall circumference of the retainer ring to be diminished, so that expansion of the retainer ring when it heats up is absorbed, and the retainer ring is not subject to kinking or folding when the catalytic converter operates in the hot condition.
摘要翻译：催化转化器包括一个管状外壳，在该壳体中保持一般为柱状的整体式催化剂体。整体式催化剂体的端部均与缓冲环接合，并且每个缓冲环与其保持环接合，该保持环基本上轴向固定在壳体内靠近其端部。单体催化剂体通过存在于外部的保持环之间的轴向压力，保持环之间的缓冲环和缓冲环之间的整体式催化剂体而被支撑在壳体内。至少一个保持环在其圆周的一部分中形成有断裂，断裂两侧的保持环的两个自由端可随着保持环的变形而移动一定距离，根据变化保持环的温度相对于彼此相对的方向，导致保持环的整个周长减小，从而吸收保持环的膨胀，并且保持环不是当催化转化器在热的条件下工作时，会发生扭结或折叠。
