摘要： One object of the invention is to provide a plug cap that more reliably prevents the leakage of current by suppressing the ingress of water from a gap between a terminal body and a rubber member.A plug cap 1 includes an electrical connection portion 5 that electrically connects a spark plug to a plug cord, a terminal body 2 that is provided on the outer periphery of the electrical connection portion 5, and a cylindrical rubber member 3 which is mounted on at least one of one end portion and the other end portion of the terminal body 2 and into which the spark plug or the like is inserted. The terminal body 2 includes a one end-side insertion portion 41 which is formed at one end of the terminal body and into which the spark plug is inserted and the other end-side insertion portion 42 which is formed at the other end of the terminal body and into which the plug cord is inserted. The rubber member 3 includes an inner cylindrical portion 31 that is inserted into the one end-side insertion portion 41 or the other end-side insertion portion 42, and a cylindrical outer cylindrical portion 32 that is positioned close to the outer periphery of the inner cylindrical portion 31. The inner cylindrical portion 31 includes annular protrusions 35 that come into contact with the inner peripheral surface of the terminal body 2.

摘要： The new structure of a ferrite core for the use of a power transformer and/or a choke coil has been found. The core is assembled by a pair of identical core halves, and each of core half comprises (a) a circular center boss(12), (b) a pair of outer walls(14,16) positioned at both the sides of said boss(12) so that a fan-shaped empty space is provided between the circular boss(12) and a pair of outer walls(14,16) for mounting a coil, (c) a pair of base plates(18,20) coupling said boss(12) with said outer walls(14,16) at the extreme end of those members so that those members conform substantially with the E-shaped structure, (d) the other extreme end of said boss(12), the outer walls(14,16) and the base plates(18,20) residing on a single plane, (e) each of said outer walls(14,16) being essentially rectangular with the external linear wall and the inner curved wall which is coaxial with the circular boss(12), and the width(d.sub.2) of said external linear wall is larger than the diameter(d.sub.3) of the circular boss(12), (f) each of said base plates(18,20) being essentially in the sector shaped having a pair of tapers which are gradually opened towards the outer walls(14,16), (g) the area(S.sub.3) coupling the base plates(18,20) with the outer walls(14,16) being larger than the half of the cross sectional area(1/4.pi.d.sub.3.sup.2) of the boss(12), (h) the area(S.sub.2) coupling the boss(12) with the base plates(18,20) being substantially the same as half of the cross sectional area(1/4.pi.d.sub.3.sup.2) of the boss(12), and (i) the area(S.sub.1) of the cross section of each of the outer walls(14,16) being essentially the same as half of the cross sectional area(1/4.pi.d.sub.3.sup.2) of the boss(12).
