Abstract: A flange 37b of a cap case 37 is provided with protrusions 37c that, before being swaging, project upward from the flange 37b. When the flange 37b is swaged along an upper surface of the cap 3, the protrusion 37c projects along the upper surface of the cap 3 from the flange 37b toward a center of the cap 3. The cap case 37 is welded to the cap 3 by friction stir welding at a welding portion 37d located at a substantially center of the protrusion 37c. The protrusions 37c are formed approximately in a letter-T shape that is symmetric left and right, and width W2 of a connecting portion 37r in a cap circumferential direction is smaller than the maximum width W1. The rigidity of the connecting portion 37r against deformation is reduced by forming a portion with small width W1 at the connecting portion 37r.

Abstract: A circuit design technology which can facilitate timing adjustment for a circuit whose layout has been designed. The circuit design method including the steps of entering design data for a circuit including a variable delay cell inserted in advance at a part where delay adjustment is expected necessary in terms of a circuit characteristic during an initial layout, analyzing timing of the entered design data, and correcting the delay in the variable delay cell when an error occurs as a result of the timing analysis.

Abstract: A circuit modification portion modifies circuit information of an integrated circuit depending on a result of a timing test at a timing test portion to presume delay information at a delay presumption portion by modeling the circuit relating to its modified circuit information. Thereafter updating the circuit information and delay information of the integrated circuit at an information update portion to re-test the timing. This allows to carry out a timing analysis/test of the modified circuit without designing layout with the modified circuit information, which is required in a conventional design method. As a result, the number of designing the layout in the integrated circuit design is reduced to shorten time required for the layout design, which allows to shorten time required for the layout design process (layout design, timing analysis/test, and timing adjustment).
