摘要： An apparatus for igniting a combustible mixture. In one example, the apparatus can include a coaxial cavity resonator assembly in a combustion environment. The apparatus can also include an operational feedback system and a controller. The operational feedback system can measure at least one of a voltage value and a current value of the coaxial cavity resonator assembly in the combustion environment. The controller can be configured to determine a condition of the coaxial cavity resonator assembly and modulate operation of the coaxial cavity resonator assembly based at least in part on the determined condition.

摘要： [Object] To prevent a sealant from intruding between a flange and a stepped portion during manufacture of a spark plug and to prevent cracking of an insulator during use of the spark plug.
[Solution] A spark plug includes a center electrode including a flange, an insulator having a through-hole extending in an axial-line direction and holding the center electrode, and a sealant filled in the through-hole to fix the flange and the insulator to each other. The insulator includes a stepped portion in which the through-hole reduces a diameter toward a front end side and that supports the flange, and a small-diameter portion that is continuous with a front end side of the stepped portion and in which the diameter of the through-hole is smaller than in the stepped portion. An angle θ1 formed by the stepped portion and a plane perpendicular to the axial line and an angle θ2 formed by the plane perpendicular to the axial line and an opposing surface of the flange opposing the stepped portion satisfies θ1−θ2≥6°. In a cross section including the axial line, a maximum diameter D1 of the flange and a diameter D2 of the through-hole at a rear end of the small-diameter portion in the axial-line direction satisfy 0.15 mm≤(D1−D2)/2.

摘要： An electric discharge device according to the present disclosure includes a discharge electrode, a counter electrode, a voltage application circuit, and a liquid supply unit. The discharge electrode is a columnar electrode. The counter electrode faces the discharge electrode. The voltage application circuit applies an application voltage between the discharge electrode and the counter electrode. The liquid supply unit supplies liquid to the discharge electrode. The liquid extends and contracts along a central axis of the discharge electrode by discharge. The counter electrode includes a peripheral electrode part and a projecting electrode part. In a direction along the central axis of the discharge electrode, a tip of the liquid in a state in which the liquid extends is located at the same position as an outer peripheral edge of the peripheral electrode part or located closer to the discharge electrode than the outer peripheral edge.

摘要： The spark plug includes a cylindrical insulator, a center electrode provided in the insulator, and a cylindrical metal shell provided around the insulator. A ledge portion of the metal shell has a frontward facing surface facing a front side, a rearward facing surface facing a rear side, and a connection surface connecting the rearward facing surface and the frontward facing surface. The rearward facing surface engages with a step portion of the insulator. The metal shell includes a front cylindrical portion connected to the front side of the ledge portion. The inner circumferential surface of the front cylindrical portion is connected to the frontward facing surface of the ledge portion via a chamfered surface or a rounded surface. A corner at which the connection surface and the frontward facing surface are connected is located on the front side with respect to a front end of the insulator.

摘要： A method of producing a cylindrical insulator for a spark plug includes a molding step of forming ceramic powder filled in a cavity defined by a mold and a molding pin into a compact. In a first removal step of removing the compact from the mold, the compact has at least one protrusion formed in at least one recess of the molding pin formed in an outer cylindrical surface of the molding pin, and the at least one protrusion is locked in the at least one recess, thereby allowing the compact to be removed with the molding pin from the mold. In a second removal step of removing the molding pin from the compact, the molding pin is turned or rotated in the circumferential direction about the compact, causing the at least one recess to cut the at least one protrusion from the compact, and thereafter the molding pin is removed from the compact.

摘要： A spark plug includes a tubular metal shell; an insulator including a locking portion locked onto the metal shell; and a cap disposed at a front end side of the metal shell, the cap having a plurality of orifices. The plurality of orifices include orifices with different cross-sectional areas. A sum of the number of one or more largest orifices and the number of one or more large orifices that have a cross-sectional area of larger than or equal to 90% of the one or more largest orifices is smaller than the number of orifices that are other than the one or more largest orifices and the one or more large orifices. A length of the front end portion in an axial direction between a front end of the insulator and a front end of the locking portion is smaller than or equal to 12 mm.

摘要： A spark plug housing. The spark plug housing includes an inner side, an outer side, and a longitudinal axis, which extends from an end of the spark plug housing facing toward the combustion chamber up to an end of the spark plug housing facing away from the combustion chamber. The spark plug housing includes a circumferential shoulder on its inner side, which is designed so that a spark plug insulator rests thereon, and a corrosion protection layer on its inner side, which is formed on a section of the inner side of the spark plug housing, the section extending from the end of the spark plug housing facing toward the combustion chamber to at least over the shoulder and along the inner circumference of the spark plug housing.

摘要： A safety guard for an ammunition cartridge (cartridge) of a conductive energy weapon (CEW) includes a body having a first electrical contact on a first side of the body and a second electrical contact on a second side of the body opposite the first side of the body. The first and second electrical contacts are in electrical communication with each other through the body. The first and second electrical contacts are configured to contact a first electrode of the cartridge and a second electrode of the cartridge, respectively, when the body is placed over the cartridge. The safety guard is configured to prevent the cartridge from firing when a firing input, such as a trigger pull, is received by the CEW from a user. In implementations the body includes at least one clip having a projection configured to be inserted in a corresponding depression of the cartridge of the CEW.
