摘要： An axial end portion of a dielectric sheet, which is wound around a central core of an ignition coil, includes an axially projecting portion, which projects from an axial end surface of the central core positioned radially inward of primary and secondary coils in a case. An inner peripheral side axial end corner and an outer peripheral side axial end corner in the axially projecting portion are respectively formed into a blunt smooth round shape. Dielectric resin is filled in spaces in the case. Alternatively, the axially projecting portion may have a folded end portion, which includes a plurality of generally arcuate segments folded one after another on one circumferential side thereof.

摘要： In a stick coil, there is disclosed an ignition coil for an internal combustion engine which can prevent a crack (a collar leak) from being generated due to a thermal stress. In this ignition coil, the structure is made such that a size (L) of a portion which is in parallel to an axial direction of a primary spool (121) in a projection portion (121b) is larger than a size (T) of a portion which is in parallel to an orthogonal direction to the axial direction of the primary spool (121). Accordingly, a frontal projected area of the projection portion (121b) as seen from a flowing direction of a resin becomes small, a resin flow is hard to get out of order at a time when the resin flows through a portion corresponding to the projection portion (121b) at the forming time, and a convoluted void and a weld are hard to be generated. Accordingly, since it is possible to prevent a mechanical strength in a root portion of the projection portion (121b) from being reduced, it is possible to previously prevent a crack from being generated in the root portion of the projection portion (the collar portion) (121b) due to a thermal stress so as to reduce an insulating property.
摘要翻译：在棒状线圈中，公开了一种用于内燃机的点火线圈，其可以防止由于热应力而产生裂纹（轴环泄漏）。在该点火线圈中，该结构被制成使得与突起部分（121b）中的初级线轴（121）的轴向方向平行的部分的尺寸（L）大于与主卷轴（121）的轴向的正交方向平行的部分。因此，从树脂的流动方向看，突出部分（121b）的正面投影面积变小，在树脂流过与突起部分相对应的部分时，树脂流动难以变得不顺利（121b），并且难以产生卷积的空隙和焊缝。因此，由于可以防止突起部（121b）的根部的机械强度降低，所以能够防止在突起部（轴环部）的根部产生裂纹，（121b）由于热应力而降低绝缘性能。

摘要： To provide a method for producing a ceramic porous material which has a high strength, though it has a high porosity, and which is excellent in permeability without dust generation. In a ceramic porous material having a three-dimensional mesh-like skeleton structure with a large number of substantially spherical adjacent cells communicating with each other via communication holes, the crystal particle size at the rim of each communication hole in the skeleton structure is provided substantially equal to the crystal particle size in the other parts.
