Disclosed is a saw blade capable of rapid cutting for various objects, such as jewelry, ferrite materials, stone, metallic materials, or ceramic tiles. The shape of the saw blade is modified such that performance and life time of the saw blade are improved. And also the manufacturing process for the saw blade is simplified, thereby reducing the manufacturing cost for the saw blade. The cutting tip is formed at upper and lower surfaces thereof with a mesh pattern, thereby enhancing the cutting performance by 30% as compared with that of a conventional cutting tip. The cutting tip represents superior cooling efficiency so that body of the saw blade is not broken during the cutting process, thereby ensuring safety of a worker and expanding the life time of the saw blade. The life time of the cutting tip is controlled by adjusting the content of diamond powder contained in the segment on the basis of hardness of a metal bond, regardless of the chemical composition and composition ratio of the metal bond contained in the segment. The cutting tip is suitable for various objects to be cut and the saw blade having the cutting tip is easily fabricated according to applications thereof, so that the manufacturing process for the saw bladeis simplified and the manufacturing cost for the saw blade is significantly reduced.

An electrical plug connector (1) in the form of a socket contact with a contact inner part (3) for making electrical contact with a pin (2), and with an outer spring (4) which surrounds the contact inner part (3), the contact inner part (3) is, according to the invention, formed from nickel silver.

The invention relates to a bottle lifting device for a filling machine. The bottle lifting device comprises a false cup, a bottle clamping plate, and a cylinder which is arranged above a filling valve; a roller seat on which a roller is arranged is arranged on a telescopic part of the cylinder; guide rods are respectively arranged at two sides of the roller seat; one end of each guide rod, far away from the roller seat, is connected with the false cup; the bottom end of the false cup is connected with the bottle clamping plate; the false cup is positioned below an opening of the filling valve; axes of the cylinder and the filling valve and a longitudinal center line of the roller are overlapped. According to the bottle lifting device for the filling machine, the roller, the false cup, the bottle clamping plate, the filling valve and the cylinder are connected as a whole structure; the cost is small; when in filling, the cylinder upwards moves under the effect of compacted air, and the bottle clamping plate is driven by the roller seat together with the guide rods to move upwards, so as to prop a bottle opening to the opening of the valve for filling; after the filling, the roller downwards moves, and the bottle clamping plate is driven by the guide rods to downwards move, so as to enable a bottle to be separated from the opening of the valve; the force applied during lifting or lowering is concentrated in the direction of the axis of the filling valve, so that the filling precision can be effectively increased.

The invention provides a Class 1E control cable for a third-generation passive nuclear power plant and a production method thereof. The third-generation passive nuclear power plant mild environment 1E level control cable includes a conductor, the outer wall of the conductor is extruded with an inner insulation layer and an outer insulation layer and wrapped with a tape to form a core, and multiple cores are placed in the filler and stranded to form a cable core. The cable core is sequentially provided with a tape layer, a composite shielding layer, a wrapping layer and a sheath layer from the inside to the outside. The production method of the 1E-class control cable includes the following steps: including conductor stranding; inner insulation layer and outer insulation layer extrusion; inner insulation layer and outer insulation layer irradiation cross-linking treatment; insulation wrapping; cabling? Extrusion of filling layer? Shielding? Extrusion of sheath layer? Radiation cross-linking treatment of sheath layer.
