An ignition device includes: an axially extending chamber with an opening portion to be open to a cylinder and a bottom surface facing the opening portion; an outer electrode provided around the opening portion; and a center electrode that forms the bottom surface. When a voltage is applied between the center electrode and the outer electrode, a plasma is produced in the chamber and a plasma jet is injected through the opening portion. The ignition device includes: a metal housing formed integrally with or separately from the outer electrode; an insulating member that supports the center electrode while insulating the center electrode from the housing and the outer electrode; and a screw thread formed on a periphery of the housing by which the ignition device is screwed into a cylinder head of the internal combustion engine. A gasket is disposed in a side closer to the inside of the cylinder. A peripheral wall of the chamber is formed by the insulating member.

The present invention relates to a kind of natural style jujube wood floor board and its production process. The natural style jujube wood floor board is produced with jujube wood possessing special texture including faults and through artificial treatment. It is natural, primitive, native and especially suitable for matching with ancient furniture.

The invention relates to a pair of split gloves for a touch screen. Each glove comprises a body half cover and five finger part covers; the opening parts of the finger part covers are connected with the finger root of the half cover; two or more finger part covers are made of a conductive cloth material; an annular ring wraps each end part, where a finger extends, of the finger root end part of the body half cover; an annular constraining strap is designed at the opening part of each finger part cover. The annular constraining straps are made of an elastic material and can be used for automatically constraining and connecting the annular rings when being sleeved on the annular rings. According to the gloves, an operator can directly operate the touch screen without taking off the gloves, the finger part covers of the spilt gloves for the touch screen can be independently replaced when being damaged, and the finger part covers can adopt different colorful patterns to be matched with the body half cover for use.

The invention discloses a method for manufacturing electronic matrix excitation-type image-text fireworks. The method comprises an image-text firework carrier and an electronic matrix excitation-type method; the image-text firework carrier is equipped with a carrier casing and a lattice structure body; firework units are mounted in the lattice structure body, and are connected with an electric control main board through a matrix dot excitation circuit board; a signal receiving sensor is arranged on the electric control main board; the electronic matrix excitation-type method comprises the following steps: designing image-text sample, compiling the image-text sample into electric signal, storing the electric signal into the electric main control board, setting off the image-text firework, receiving signal by the signal receiving sensor after the image-text firework is set off; and driving the matrix dot excitation circuit board by the electric main control board to excite the firework units according to rules. The product provided by the invention is compatible with each other, the shape is not limited, the method is suitable for production in large scale, the signal can be stored just before setting off, the display regulation is controllable, the image-text is various, and the emotion is expressed directly.

The invention belongs to the field of sport equipment, and particularly discloses a wide-angle table tennis intelligent ball serving machine. The machine comprises a base frame, a ball driving circular plate, a ball serving ring, a ball serving motor, a ball distributing mechanism, a ball delivering part and a controller. The ball driving circular plate is internally provided with a ball inlet, aball sliding passage and a ball driving part which are used for table tennis balls to slide to a side portion from the ball inlet to be served; the ball serving ring is internally provided with sliding grooves matching with the ball driving part, and a ball serving pipe is arranged on the edge. The ball distributing mechanism is arranged in the ball driving circular plate and used for distributingand blocking the table tennis balls. The ball driving circular plate is arranged in the ball serving ring and fixed through a bearing through a shaft connecting part and two supporting frames of thebase frame, and the ball driving circular plate is rotated relative to the ball serving ring. The ball delivering pipeline of the ball delivering part is communicated with the shaft connecting part and used for delivering the table tennis balls into the ball inlet through the shaft connecting part. The controller is used for controlling the ball serving machine to adjust the serving angles and serving speed of the table tennis balls in the longitudinal and transverse directions. According to the ball serving machine, the serving angles of the table tennis balls are wide, the ball serving manner is complicated, the training difficulty is high, and therefore training demands of different users of different levels are met.
