  • Patent number: 7315110
    Abstract: A spark plug according to the invention has a length and an outer side surface. The outer side surface includes a plurality of closed band-shaped regions arranged in the lengthwise direction of the spark plug, within each of which a plurality of identical marks, which represent the same piece of information concerning the spark plug, are formed at predetermined intervals in a circumferential direction of the spark plug. Further, the marks within each of the regions represent the piece of information different from that represented by the marks within any other one of the regions, and each of the marks within each of the regions is aligned in the lengthwise direction of the spark plug with one of the marks within any other one of the regions. With such formation of marks, the spark plug can be accurately identified without rotating it to a specific position during the identification process.

  • Publication number: 20070216278
    Abstract: A spark plug is disclosed as having a metal shell, a porcelain insulator fixedly secured to the metal shell, a center electrode and a ground electrode providing a spark discharge gap with the center electrode. The porcelain insulator has a through-bore partially exposed from an end face of the ground electrode in a surface area S1, as viewed from a distal end of the spark plug, and having a total surface area S2 falling in the relationship S1/S2?0.3. The center electrode protrudes from the porcelain insulator with a protruding length L under the relationship L?0.6 mm. A minimal value Hmin and a maximal value Hmax in distance between the ground electrode and the end face of the porcelain insulator lies in the relationship Hmax/Hmin?1.3. Wall thickness T between the through-bore and an outer periphery of the porcelain insulator lies in the relationship T?0.7 mm.

  • Publication number: 20070194681
    Abstract: A spark plug for an internal combustion engine is provided which is equipped with a ground electrode and a center electrode. The spark plug also has a ground electrode noble metal chip joined to the ground electrode and a center electrode noble metal chip joined to the center electrode to define a spark gap between itself and the ground electrode. At least one of the ground electrode chip and the center electrode chip is made from material containing a main component of Rh (Rhodium) and an additive of 0.3% to 2.5% by weight of one or more selected from earth rare elements, IVA elements, and VA elements. This results in enhanced resistances of the one of the center electrode and ground electrode chips to wear arising from exposure to sparks and oxidation in high-temperature environments.

  • Patent number: 7054132
    Abstract: A variable capacitance element includes a movable element provided above a substrate using supporting portions and support beams so as to be displaced from the substrate. An insulating film and a movable electrode are provided on a conductor facing surface of the movable element. A driving electrode is arranged to displace the movable element, between a signal cutoff position and a signal passage position, whereby a high frequency signal transmitted through a transmission line is cut off or allowed to pass. The insulating film uses compressive stress to warp the movable element and the movable electrode in a direction of warping in a convex form toward the transmission line, and maintains this warping direction.
