A mechanical seal device which is reduced in friction when seal surfaces slide on each other, prevented from abrasion on seal surfaces, is prevented from abnormal abrasion on the seal surface of a sealing ring and joining split surfaces, is prevented from seizure or squeal phenomena on seal surfaces when seal surfaces are abrasion-rotated and kept in a dry-friction state, is simplified in structure thereof, and is easier to assemble and disassemble. The mechanical seal device is a split type mechanical seal device that seals fluid to be sealed by being mounted to a surface outside a machine between a hole in a housing and a rotary shaft inserted into the hole, and comprises a split stationary sealing ring mounted and fixed to the rotary shaft by embracing it from the opposite sides, and a split rotating sealing ring fixed to the rotary shaft by embracing it from the opposite sides, wherein a clearance through which to permit fluid to be sealed to flow is provided between the inner peripheral surface of the split stationary sealing ring and the rotary shaft, and a rubber or resin sealing layer is provided on at least one of the seal surface of the split stationary sealing ring and the opposing seal surface of the split rotating sealing ring.

The invention discloses a noble metal-coated copper wire for ball bonding, with a wire diameter between 10 [mu]m or more, and 25 [mu]m or less, the noble metal-coated copper wire including a core material having a copper alloy having a copper purity of 98 mass % or higher, and a noble metal-coating layer formed on the core material. The noble metal-coating layer includes a palladium cavitating layer containing palladium; at least one element selected from the group consisting of Group 13 to 16 elements or an oxygen element, finely dispersed in the palladium; and a diffusion layer formed of copper diffused into the palladium. According to the invention, the noble metal-coated copper wire for ball bonding can enable a palladium enriching layer to be evenly dispersed on the entire surface of the fusion copper ball of the core material and the palladium does not flow into a solidified copper ball, such that cavities do not form. The noble metal-coated copper wire here is suitable for mass production.

The invention provides a safety evaluation test device. The safety evaluation test device of the present invention is constituted such that gas containing explosive components, etc. generated when the safety evaluation test is performed on the Li-ion battery module (2) is connected with the gas supply mechanism (10), etc., and the auxiliary gas supply mechanism (30). ), etc. are discharged through the pipe (40) together, so the generated gas containing explosive components will not have a bad influence on the next test.

The present invention is applicable to the technical field of storage devices, and provides a storage box for sampling equipment for geological resource exploration, including a box body. A mounting plate is fixedly installed near the bottom of the box body, and the mounting plate is annular and uniform. In addition, a plurality of fixed components for placing drill pipes are installed at intervals, and a plurality of cleaning components are installed on the inner wall of the box, and a chute is provided on the mounting plate, and the brushing component is slid in the chute, The bottom of the box body is fixedly installed with a driving assembly for driving the fixed assembly to rotate; the present invention adopts the above technical solution, which can effectively increase the storage time of the drill pipe, and during the storage process, the drill pipe can be cleaned and maintained, directly Increase the service life of the drill pipe, reduce the replacement frequency of the drill pipe, and reduce the cost of use.

The invention discloses an automatic temperature-rising power transmission line system comprising a lead wire part, a temperature rising part and a ventilation part, wherein the inner part of the lead wire part is a hollow cavity; the hollow cavity is communicated with the ventilation part; the temperature rising part is fixedly arranged on the lead wire part; the temperature rising part comprises a heating body and two magnetizers which are mutually symmetrical; the heating body is provided with a through hole; the upper ends of the two magnetizers are hinged; convex magnetism-conducting strips are respectively arranged in the middles of the two magnetizers; after the two magnetizers are mutually contacted, a closed loop is formed by the convex magnetism-conducting strips and the two magnetizers; one of the magnetism-conducting strips is wound by a coil; one end of the coil is connected with a first double-metal sheet; and the other end of the coil is connected with the heating body. With the adoption of the structure, a condition of adhering ice and snow on a power transmission line can be prevented and the condition that the pressing force borne by the power transmission line is too large so that the power transmission line shakes and even is cracked can be avoided; and therefore, the normal work of the power transmission line is guaranteed.

In the conventional substrate processing method, it is not possible to designate the size of the tip shape for fabrication, and it is not possible to obtain a substrate having a desired arbitrary diameter. In addition, impurities may adhere to the substrate. Using the relationship between the diameter of the front end of the substrate and the applied voltage or the enclosed time when the front end of the substrate is being processed, the applied voltage to obtain the desired front end diameter is controlled to process the substrate. Thereby, a substrate having a desired arbitrary diameter can be produced within a range in which the tip diameter of the sharpened tungsten single crystal filament is in the range of 0.1 μm to 2.0 μm.

The invention provides a copper alloy bonding wire, the copper alloy crystal grains per unit cross-sectional area are 50-250, the maximum grain size is less than 1 / 3 of the diameter of the bonding wire, and the specific direction is less than 40%. of no directionality.

The invention provides antibacterial and moldproof polymer modified spray asphalt waterproof paint and an application method thereof. The paint is composed of a component A and a component B. The component A is prepared from, by weight, 90-120 parts of anionic emulsified asphalt, 40-90 parts of polymer emulsion, 0.5-5 parts of a thickening agent and 10-60 parts of filler. The component B is prepared from, by weight, 100 parts of water, 5-15 parts of a curing agent and 0.5-5 parts of an antibacterial agent. The invention further provides the application method of the antibacterial and moldproof polymer modified spray asphalt waterproof paint. The antibacterial and moldproof polymer modified spray asphalt waterproof paint has high ductility, high resilience and high adhering strength, is antibacterial and moldproof, excellent in low-temperature performance and high in construction speed and can be closely connected with a basic layer, and influences of deformation of the basic layer on the waterproof performance of a material can be effectively resisted; meanwhile, the situation that bacteria are bred on the surface of a coating film, and the coating function of a waterproof layer is damaged can be effectively prevented, and the possibility that an antibacterial agent has secondary pollution on water is reduced.

Provided is a web cutting device capable of preventing dust generated when cutting a web from being attached on the surface of the web. When the web is cut in a width direction while a prior web (W1) and a new web (W2) overlap up and down, a cutting space (98, 99) where a cutter (58) moves is formed by an upper moving groove part (28) and a lower moving groove part (96). The generated dust is absorbed by a dust absorbing unit (102) while cutting the prior web (W1) and the new web (W2) by the cutter (58).
