Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To provide an ignition coil which can generate a desired high voltage and can be assembled easily, by suppressing the occurrence of cracks in a resin insulating material near the inner peripheral corners of both end sections of an outer peripheral core in the axial direction, without enlarging the physical body of the coil in the radial direction. SOLUTION: In an ignition coil, an outer peripheral core 25 is not in direct contact with an epoxy resin 26, because the inner peripheral corner of the end section of the core 25 positioned on the higher voltage side of a secondary coil 21 is covered with a corner member 50, and the inner peripheral corner of the end section of the core 25 on the lower voltage side is covered with another corner member 55. Each corner member 50 (55) is composed of a rubber ring 51 (56) and a metallic ring 52 (57). Therefore, the ignition coil can generate a desired high voltage by preventing the occurrence of cracks in the epoxy resin 36 near the inner peripheral corners of both end sections of the core 25. In addition, the corner member 50 (55) can be assembled easily, by the reinforcement of the metallic ring 52 (57) to the member 50 (55), because the member 50 (57) is not deformed.

Abstract: PURPOSE:To make the projected and recessed parts produced when pressed on the surface of a multilayer printed wiring board very small as compared with those formed when an aluminum plate is used by using a film formed of a synthetic resin having a softening point higher than a specific temperature as an intermediate plate. CONSTITUTION:During press molding performed for manufacturing a multilayer printed wiring board, an intermediate plate formed of synthetic resin film 5 having a softening point of >=150 deg.C is used. Since the film 5 does not soften in the pressing temperature range of >=150 deg.C, the projected and recessed parts formed on the surface of the wiring board become very small as compared with those formed when an aluminum plate is used when a pressure is applied at the time of press forming. A void-less multilayer printed circuit board having surface roughness of 20mum can be obtained, for example, by constituting laminated boards 2 respectively covered with copper foil on one sides on both sides of an internal layer 3 with a patterned circuit with prepreg 1 in between and alternately stacking up films 5 of polyether sulfone and the four-layer boards 4 thus constituted between the upper and lower hot plates in a press, and then, forming the alternately stacked up films 5 and boards 4 for 90 minutes under a condition of 170 deg.C in temperature and 20kg/cm<2> in pressure.
