The invention relates to a special-shaped wire strand cable conductor and a production method of the special-shaped wire strand cable conductor and relates to a wire and cable special-shaped wire strand round conductor with the nominal cross section ranging from 25 mm<2> to 630 mm<2>. The cable conductor comprises a single round wire and special-shaped wires with all the strand layers designed in the tile-shaped structure according to the specifications of cables. The production method includes the steps that first, according to the designed special-shaped wire structure, the single round wire in the center is manufactured in a drawing mode through a drawbench, and then the special-shaped wires of various specifications of strand layer structures are manufactured on a water tank type or sliding type or fractional motor type drawbench in a drawing mode through a special-shaped high-speed wire drawing die; the round line in the center is placed on a payoff rack of a wire stranding machine, and all the stranding layer special-shaped wires are placed on a frame winch or fork winch and manufactured into the special-shaped wire strand cable conductor through stranding. The outer surface of the cable conductor is smooth and free of burrs, the gap between single wires is small, the filling coefficient is larger than 0.98, and the strand cable conductor is stable in structure. The production method is high in technology universality, and updating and upgrading of the products can be achieved in small and medium-sized enterprises through the technology.

The invention discloses a camera rotation control method applied to a mobile terminal and the mobile terminal. The mobile terminal comprises a terminal body and a camera device. The camera device can rotate relative to the terminal body and comprises a magnet. The position, corresponding to the camera device, of the terminal body is provided with a digital Hall sensor. The camera rotation control method includes: receiving an instruction to rotate the camera, in which a target angle is carried; detecting a value of the digital Hall sensor; according to the detected value of the digital Hall sensor as well as a table of correspondence between the value of the digital Hall sensor and an angle of the camera device, determining a current angle of the camera device; calculating an angle to be finished; rotating the camera device to the angle to be finished, through a motor. The camera rotation control method and the mobile terminal according to the technical scheme have the advantages that optionally angular rotation is allowed for the camera, and the service life of the motor used for controlling rotation of the camera is prolonged.

The invention is applicable to the technical field of control, and provides a method and device for controlling the rotation of a camera with gestures and an infrared gesture sensor. The method includes: acquiring infrared intensity value change information collected by an infrared gesture sensor; obtaining the hand's swipe direction according to the infrared intensity value change information, and obtaining the hand's swipe direction from a preset mapping relationship according to the hand's swipe direction A camera control instruction corresponding to the swipe direction; controlling the camera to rotate to a position corresponding to the control instruction according to the control instruction. The above method uses the infrared gesture sensor to sense the swipe direction of the hand, realizes the gesture control camera to rotate to the front or rear position, and improves the control accuracy, and solves the problem that the existing technology of controlling the camera rotation is prone to motor idling The problem.

The invention belongs to the field of control technologies, and provides a method and device for controlling rotation of a mobile terminal camera and a mobile terminal. The mobile terminal comprises a digital Hall sensor. The method includes the steps that control information of the camera is obtained, wherein the control information of the camera includes the rotating direction of the camera; according to the control information, the camera is controlled to rotate in the rotation direction; in the rotation process of the camera, the output value of the digital Hall sensor is obtained, and the angle, corresponding to the output value, of the camera is obtained according to the output value; when the angle of the camera reaches a preset threshold value, a preset angle corresponding to the preset threshold value is obtained, and the camera is controlled to rotate by the preset angle in the rotation direction from the current position. By the adoption of the method, the camera is controlled to accurately rotate to a target angle from any initial angle, motor idling does not exist, and the problems that through an existing mode, because a motor idles, power is consumed, and heat is generated are solved.

The invention relates to the technical field of amino resin production, provides a method capable of preparing full-water-soluble high-imino partial-methylated amino resin which cannot be saturated when the resin is dissolved in water in order to solve the problem that a saturation phenomenon can be produced when the water-soluble resin is dissolved in water, provides equipment which is used for preparing the full-water-soluble high-imino partial-methylated amino resin, has a wide reversing range and good shock insulation effect and can change height of stirring blades according to height change of a material in a container, and solves the problems that a bend is required to be manufactured for reversing under the condition that a direction of a reaction kettle at a feed port and a trend of a feed pipe cannot be adjusted to the same, efficient material stirring and avoidance of a stirring blade idling phenomenon cannot be realized simultaneously during the height change of the material and the shock insulation effect is poor. The preparation equipment comprises the container and a stirrer, wherein the container is provided with shock insulation legs and the feed port adjustable in the feeding direction, the height of each stirring blade of the stirrer is adjustable, and a motor is provided with a terminal.

The invention discloses a self force augmentation type bidirectional wrench and an operating method thereof. The self force augmentation type bidirectional wrench comprises a handle, a force-augmentation reversing part, a reversing switch, a shifting lever and a sleeve. The force-augmentation reversing part comprises an input shaft, an intermediate shaft, a reversing shaft, an output shaft, an input gear, a transmission gear, a forward gear, a reverse gear, an output gear, a spring and a steel ball. The output gear can be selected to be engaged with the forward gear or the reverse gear through the reversing switch so that the output shaft and the sleeve can rotate in the same direction as the handle or rotate in the direction opposite to the rotating direction of the handle, and the force moment of the handle can be amplified through two-stage gear transmission. The self force augmentation type bidirectional wrench is simple in structure, convenient to operate, capable of screwing and unscrewing screws in two directions, and capable of saving strength.

A needle blade roll (12) for forming short fibers from a material capable of formation of artificial cotton in an artificial cotton fabricating apparatus is disclosed which is made up of a roll main body (13) and a large number of needle blades (14) implanted into a peripheral surface of the roll main body (13). In the needle blade roll (12), each needle blade (14) is arranged at a sloping angle relative to a radial line of the roll main body (13) so that its leading end lies ahead of the radial line with respect to the rotational direction of the roll main body (13). This makes it possible to form short fibers the length of which is longer than conventional, thereby fabricating artificial cotton made of such short fibers which are fully intertwined with one another.
