    • A compact dielectric band elimination filter, which is composed of fewer components and can be produced in fewer production steps, uses a resonator apparatus having a dielectric block with a plurality of throughholes each containing an inner conductor and serving as a resonator. Capacitor electrodes are formed on a main surface of the block such that series-connected resonant capacitors are provided with the inner conductors inside the throughholes. The resonator apparatus is mounted on a substrate of a layered structure having an inductor thereon. Each trap frequency of the filter associated with one of the resonators can be adjusted by making adjustments on the associated resonator without affecting the characteristics of the adjacent resonators, by forming a larger-diameter part and a smaller-diameter part separated by a step inside each throughhole or by using a dielectric block having a wider part and a narrower part through which throughholes with a uniform inner diameter are formed, such that the even-mode input impedance and odd-mode input impedance of each resonator will be equal to zero at the trap frequency associated therewith.

    • A plasma ignition system includes an ignition plug attached to an engine and having a center electrode, a ground electrode, and a discharge space, a discharge power source circuit, a plasma generation power source circuit, a resistance element between the discharge power source circuit and the center electrode, a rectifying device between the plasma generation power source circuit and the center electrode, and an element receiving portion in a periphery of the center electrode. The plug puts gas in the discharge space into a plasma state to ignite a fuel/air mixture in the engine, as a result of application of high voltage to the plug by the discharge power source circuit and supply of high current to the plug by the plasma generation power source circuit. The resistance element and the rectifying device are placed in the receiving portion.

    • A plasma type ignition plug for igniting an internal combustion engine is disclosed having a negative electrode, a positive electrode, and a discharging distance fixing member, which includes an electrically conductive material replenishing section, made of an electrically conductive material available to melt when subjected to a heat of gas in plasma state, and an electrically conductive material replenished section to which the electrically conductive material is replenished. The discharging distance fixing member is covered on a surface of the negative electrode for initiating the spark discharge between a surface of the discharging distance fixing member and the positive electrode so as to avoid a fluctuation in a spark discharge distance caused by a wear of the negative electrode due to a collision of gas in the plasma state.
