摘要： An ignition coil 100 includes a coil section 10―which in turn includes a coil case 15, a primary coil 12 and a secondary coil 14 accommodated within the coil case 15, and an insulating molded layer 16 filling the coil case 15―and a coil core C including a center core section 20 and a yoke section 30. The ignition coil 100 is mounted on an engine body EB such that the coil core C is insulated from the engine body EB, by means of a mounting section 70. The mounting section 70, together with an insulating filling section 60 filling at least partially a gap S formed between the coil section 10 and the coil core C, which face each other, is integrally formed of a polymeric material through integral injection molding. That is, the ignition coil 100 is mounted on the engine body EB by means of the mounting section 70, which, together with the insulating filling section 60 filling the gap S formed between the coil section 10 and the coil core C, which face each other, is integrally formed of a polymeric material through integral injection molding.
Consequently there is disclosed an ignition coil of excellent durability and reliability that is capable of suppressing occurrence of leakage between a secondary coil and a coil core and suppressing generation of corona discharge across a gap between a coil section and the coil core to thereby suppress erosion of, for example, a coil case, which accommodates the primary and secondary coils, even when the maximum-voltage generation capability of the secondary coil is enhanced as a result of, for example, increase in discharge voltage of a spark plug, and the ignition coil is operated continuously for a long period of time, as well as to provide an ignition unit using the ignition coil.摘要翻译： 点火线圈100包括线圈部分10，该线圈部分10又包括容纳在线圈壳体15内的线圈壳体15，初级线圈12和次级线圈14以及填充线圈壳体15的绝缘模制层16和线圈 包括中心芯部分20和磁轭部分30的磁芯C.点火线圈100安装在发动机主体EB上，使得线圈芯C通过安装部分70与发动机主体EB绝缘。安装部分 70与绝缘填充部分60一起填充至少部分地形成在彼此面对的线圈部分10和线圈芯C之间的间隙S，通过一体注射成型由聚合物材料整体形成。 也就是说，点火线圈100通过安装部分70安装在发动机主体EB上，安装部分70与绝缘填充部分60一起填充形成在线圈部分10和线圈芯体C之间的间隙S， 另一个，通过整体注射成型由聚合物材料整体形成。 因此，公开了具有优异的耐久性和可靠性的点火线圈，其能够抑制次级线圈和线圈芯之间的泄漏的发生，并且抑制线圈部分和线圈芯之间的间隙的电晕放电的产生， 从而抑制例如容纳初级线圈和次级线圈的线圈壳体的侵蚀，即使当由于例如火花塞的放电电压的增加而使次级线圈的最大电压产生能力增强时 并且点火线圈长时间连续运转，并且提供使用点火线圈的点火单元。

摘要： The present invention provides an apparatus for measuring the concentration of a constituent to be detected in exhaust gas, which apparatus is capable of detecting with a high accuracy the concentration of the constituent to be detected in exhaust gas even though oxygen concentration in the exhaust gas varies. In an exhaust gas sensor 1 for use in the measuring apparatus, exhaust gas is introduced into spaces 15, 16 on both sides of an oxygen concentration cell element 4, and the oxidation catalyst activities of first to third electrodes 11 to 13 are adjusted so that there occurs a difference between the space 15 and the space 16 in the consumption of the constituent to be detected, which consumption is caused by the oxidation of the constituent. Thus a concentration cell electromotive force is generated in the oxygen concentration cell element 4, and an oxygen pump element 3 pumps oxygen into or out of the space 15 so that the electromotive force is held at an target value EC not more than 10 mV. The pump current at this time is taken as the detection output on the constituent to be detected. The strengths of the oxygen concentration cell element 4 and of the oxygen pump element 3 can be increased by the provision of an integrated sintered body in which the elements 4 and 3 are laminated together with the space 15 formed between the first electrode 11 and the second electrode 12. Besides, the accuracy of detecting the constituent to be detected can be improved by the control over the temperature of the oxygen concentration cell element 4 and by the temperature compensation to the pump current.
