    摘要: In an ignition coil for an internal combustion engine, a column section and a notched section are provided in a side wall section of a case section of the ignition coil. A ventilation opening is formed in an up/down direction in the column section. The ventilation opening communicates with a ventilation passage formed between a sealing rubber and the case section and is open in an upper end section. A cover surrounding the column section and covering the upper end section is provided in the side wall section. A sealing section sealing the notched section is provided in the cover. The ignition coil has a filler resin that fills a space within the case section being in continuous contact with the sealing section and the side wall section and fixing the cover to the side wall section.

    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: An ignition coil for an internal combustion engine has a first housing, a second housing, a holder, an insulating resin and a crack extension restrictor. The first housing encloses a center core, a primary coil and a secondary coil. The second housing has an install portion and a cylinder-shaped fitting portion fitted to a top cylindrical portion of the first housing. The holder is laid over top ends of the primary and secondary coils. The insulating resin is charged in an annular cavity defined at least by uppermost portions of the primary and secondary coils, the fitting portion and the holder and in contact with the fitting portion. The crack extension restrictor is formed by a part of the fitting portion and a part of the holder and disposed above the fitting faces of the fitting portion and the top end portion.

    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.
