Four magnetic layers consisting of upper and lower magnetic layers and intermediate magnetic layers are laminated to form a laminated unit. Two signal lines are disposed side by side between the intermediate magnetic layers, and two ground electrodes sandwich the intermediate magnetic layers therebetween so as to form a transmission line. A dielectric member is disposed between the two signal lines. With this configuration, a common-mode signal is attenuated by utilizing magnetic loss in the magnetic layers. In contrast, by providing the dielectric member, a normal-mode signal is allowed to propagate by reducing the effective relative magnetic permeability while preventing the occurrence of blunt waves.

The invention relates to an air-conditioner air inlet, which comprises a rectangular air inlet frame, wherein the inner side of the frame is provided with rhombic blades; the quantity of the rhombic blades is set according to actual demand; the inner side of the air inlet frame is provided with supporting beams parallel to short sides; the quantity of the supporting beams is set according to the actual demand, and can be one or more; the supporting beams are provided with through holes with the same quantity as that of the rhombic blades; all the rhombic blades pass through the through holes and can flexibly rotate by 360 DEG in the through holes; and the length of the single rhombic air inlet can be unlimitedly prolonged due to the adoption of the supporting beams; the single rhombic air inlet can be adjusted through 360 DEG rotation; and the middle of each blade cannot droop caused by action of gravity.

The invention provides an air inlet system of small gasoline engine classes. The air inlet system is composed of an inlet pipe flange, an inlet pipe, an air storage bag, a carburetor, a carburetor support, an air filter and a negative pressure pipe. The air inlet pipe flange is arranged on the air inlet pipe and is fixedly connected with an air inlet of an engine cylinder, the other end of the air inlet pipe is connected with the carburetor which is fixedly connected with a gearbox through the carburetor support, and the air filter and the carburetor are arranged side by side and is away from the engine cylinder. The air inlet system has the advantages that since the length dimension of the air inlet pipe is increased and the mounting position and direction of the air filter and the carburetor are changed, the air filter and the carburetor are away from the engine cylinder, heat of air inflow to power is reduced, the temperature of gasoline is always controlled within a distillation range point, fuel consumption, power and rotation speed of the engine can be effectively regulated and controlled, and the like.

The invention discloses a frame structure and a crane, relates to the field of engineering machinery, and is used for optimizing a structure of a traditional frame body. The frame structure comprises a frame body and support leg structures; the support leg structures are arranged at the end parts of the length direction of the frame body, and are rotationally or slidingly connected with the frame body; the support leg structures are located in an extending state; and the length directions of the support leg structures form acute angles with the length direction and the width direction of the frame body, so that the total length of the frame structure is larger than the length of the frame body, and the total width of the frame structure is larger than the width of the frame body. Under the precondition of not changing the size of the frame body, the length and the width sizes of the frame structure can be synchronously increased, so that the span of the crane is increased; and the weights of the support leg structures are far lower than the weight of the frame body in the prior art corresponding to the same span, so that the lifting weight can be increased when the span is increased.

The invention discloses a method for improving oil temperature at an outlet of an oil well and a corresponding oil well structure. The method for improving the oil temperature at the outlet of the oil well and the corresponding oil well structure are characterized in that a plurality of gravity-type sleeve-shaped heat pipes are connected into a whole and used as oil pipes so that crude oil passes through the centers of the gravity-type sleeve-shaped heat pipes and are pumped out of the oil well. Airtight spaces between pipe walls of the gravity-type sleeve-shaped heat pipes are filled with working media and are vacuumized. The lower portion of each gravity-type sleeve-shaped heat pipe is a heat pipe evaporation segment, and the upper portion of each gravity-type sleeve-shaped heat pipe is a heat pipe condensation segment. Heat passing through the bottom ends of the gravity-type sleeve-shaped heat pipes is uploaded step by step, and then the crude oil passing through the centers of the gravity-type sleeve-shaped heat pipes continuously carries out heat exchange with pipe walls so that the viscosity of the crude oil can be reduced and the crude oil can not become thick. Consequently, the temperature of the crude oil in the gravity-type sleeve-shaped heat pipes nearest to oil outlets can meet the requirement for the thickening-preventing oil outlet temperature. The method for improving the oil temperature at the outlet of the oil well and the corresponding oil well structure have the advantages of being energy-saving, simple, easy to realize and capable of substantially reducing oil extraction cost.

The invention relates to the technical field of article placing assemblies, and provides a placing shelf and a retail cabinet comprising the placing shelf. The placing shelf is provided with a plurality of rows of placing plates from the front to the back, the height of the placing plate in the rear row is larger than that of the placing plate in the front row for every two adjacent placing plates, and the included angle between the placing plate in the rear row and the horizontal plane is smaller than the included angle between the placing plate in the front row and the horizontal plane. Since one layer of the placing shelf is provided with a plurality of rows of placing plates from the front to the back, while the space utilization rate is increased, the articles can be conveniently arranged classifiedly, so that the articles are placed neatly to bring a good experience and visual effect to a user. Since the height of the placing plate in the rear row is larger than that of the placing plate in the front row for every two adjacent placing plates, goods on the placing plate in the front row do not block the goods on the placing plate in the rear row, so that the observation of thegoods on the placing shelf is facilitated. In addition, the included angle between the placing plate in the rear row and the horizontal plane is smaller than the included angle between the placing plate in the front row and the horizontal plane, so that space occupied by the placing shelf can be controlled to further improve the space utilization of the placing shelf while the pick and place of the goods is facilitated.
