The present invention relates to a method for manufacturing a contact terminal including a contact portion that slides against a surface of a conductive contact plate. The manufacturing method includes forming a projection in a metal plate by performing a drawing process, wherein the projection projects in a thicknesswise direction of the metal plate and has a larger diameter than the contact portion. The manufacturing method further includes forming the contact portion from the projection by performing a contraction pressing process at least once on the projection so that the diameter of the projection gradually decreases, while the height of the projection remains the same or decreases in a stepwise manner.

The present invention provides a polyethylene-based resin composition for foamable laminated bodies which has excellent suitability for microwave ovens and from which foam cells (foamed layer) havinga sufficient height and an excellent appearance can be obtained at excellent productivity by heating. The present invention is a polyethylene-based resin composition for foamable laminated bodies which forms, on at least one surface of a paper base, a polyethylene-based resin layer (I) for foaming, the polyethylene-based resin composition for foamable laminated bodies containing a polyethylene-based resin (A) that satisfies: a feature (a-1) of having an MFR of not lower than 6 g / 10 min but lower than 20 g / 10 min; a feature (a-2) of having a density of 0.920-0.930 g / cm3; and a feature (a-3) inwhich the percentage of an eluted substance having an elution temperature of not lower than 70 DEG C is 47-83 wt% in an elution curve obtained by means of temperature rising elution fractionation (TREF) using ortho-dichlorobenzene.

The invention relates to the technical field of unmanned vehicles, and discloses a vehicle-mounted radar system for automatic driving of vehicles, which includes a vehicle roof and a laser ranging radar, and a hydraulic telescopic rod is fixedly installed on the upper surface of the vehicle roof. The vehicle-mounted radar system for automatic driving of the car is provided with a connecting chute on the side wall of the inner ring of the base, and fixedly installed on both sides of the connecting seat installed at the bottom of the laser ranging radar. Rotate in the connecting chute. When the rotation reaches the maximum angle, the laser ranging radar will fall into the vertical groove at the bottom of the connecting chute. At this time, the pressing block is pressed down by twisting the threaded rod, so that the pressing block is tightly pressed. Hold the clamping block to realize the fixing of the clamping block. This fixing method is simple and easy to operate, and this fixing method does not use any professional fixing tools. It is more convenient, quick and easy to operate when disassembling, maintaining or replacing the laser ranging radar. .

The invention relates to a combination key for rotor support and rotor iron core connection. A primary key groove for placing a major key and subsidiary keys is a composite keyway structure; gaps between the major key and the subsidiary keys, and gaps between the subsidiary keys and a rotor punching sheet can effectively isolate radial interference and tangential interference. The major key is rectangular, and is lower than the notch of the primary key groove; the groove bottom of the major key is provided with a rectangular secondary groove. Rectangular bulges are projected from the inner circle of the rotor punching sheet, and are slightly wider than a rectangular bulge of the major key, thereby guaranteeing contact between the rectangular bulges and the subsidiary keys in a radial direction through a interference fit mode, meanwhile guaranteeing a gap between the major key and the subsidiary keys in a tangential direction, and reducing rotor punching sheet groove bottom circular bead stress concentration and yoke part magnetic field density and loss. The subsidiary keys are sectional type combination sparring taper key structures to increase a contact area in a rotor iron core axial direction; the major key and the subsidiary keys are respectively responsible for radial direction and tangential interference. The combination key is suitable for a large torque motor, especially a three generation nuclear power station circulating water pump motor, and can be used for the industries of nuclear power, metallurgy, seawater desalination, etc.

A method for enclose-planting sea-buckthorn trees and planting pasture on desert grassland is realized by cultivation of enclose-planting sea-buckthorn seedlings, preparation of enclose-planting land and planting of gesture on an enclose-planting land and is characterized in that seedlings are cultivated in a hard-branch cuttage method; cuttings are soaked in indolebutyric acid solution and then soaked in clean water, thus survival rate of seedlings is improved; after age, height, ground diameter and main roots reach at the specified standards, seedlings with more fibrous roots serve as enclose-planting sea-buckthorn seedlings; the desert grassland is continuously arranged to be square lands which are connected according to the diagonal lines, thus each enclose-planting land has four triangular lands; the enclose-planting land is dug along the edge lines and the diagonal lines to form trenches of enclose-planting sea-buckthorn trees and then the sea-buckthorn seedlings are enclose-planted; after survival, the enclose-planted sea-buckthorn seedlings form interconnected triangular forest belts for prevention and stabilization of sand; hollow triangular lands are protected and serve as effective pasture planting lands. The invention creates a sustainable environmental target for recovering of vegetation, prevention and stabilization of sands, treatment of desertification, breeding pasture for desert grassland and animal husbandry production.
