A one way gate primarily for pigs is located between a pair of parallel panels to be mounted in a fence line and includes two gate portions each defined by a transverse rail across the passage between the panels at a height above the passage and a plurality of fingers hanging from the rail separately pivotal in one direction only to the animal to pass and prevented from rotation in the opposite direction. The distance between the gate portions is less than 3.0 feet so as to be less than the length of the animal to prevent an animal being located between the rails and greater than 0.5 feet such that an animal attempting to lift the second fingers cannot simultaneously lift the first fingers.

The purpose of the present invention is to propose a structure of the longitudinal beam wheel housing area of ​​the automobile, the structure of the longitudinal beam wheel housing area of ​​the automobile of the present invention comprises the front longitudinal beam and the rear part assembly of the front wheel housing side reinforcing beam, the key is, also It includes a connecting member, the connecting member is formed by fixedly connecting the reinforcing beam and the front assembly of the front wheelhouse side reinforcing beam, the reinforcing beam is embedded in the front end of the front longitudinal beam, and is fixedly connected with the front longitudinal beam, the The front wheelhouse side reinforcement beam front assembly and the front wheelhouse side reinforcement beam rear assembly are located on the same straight line along the vehicle body length direction and are fixedly connected. Connecting the front part of the front longitudinal beam to the rear assembly of the front wheel house side reinforcement beam through the connecting member can make the front wheel house side reinforcement beam participate in the front collision process, and the connection member can effectively transmit the front collision force to the wheel house area For the side reinforcement beam, the rear assembly of the side reinforcement beam of the front wheel house is used as the transmission and energy absorption path of the front impact force, so as to reduce the intrusion of the baffle and reduce the degree of occupant injury.

The invention belongs to the field of organic functional materials, and in particular relates to a single-borinine heterocycle organic electron transportation material and a preparation method thereof. The electron transportation material provided by the invention structurally comprises double-naphthyl, a single-borinine six-membered heterocycle and substituent aryl, and has the advantages that due to the existence of a B element in a molecular structure of the electron transportation material, electrons can be directly transported in conjugated aryl, the B element and an organic light emitting electronic device along a short path, so that the electron transportation material is high in electron transportation efficiency. The single-borinine heterocycle organic electron transportation material is prepared by taking 6-chlorine-6,13-dihydrodinaphtho[2,3-b:2',3'-e]borinine, aryl lithium and palladium acetate as initial raw materials through using a one-step method. A preparation process is simple.
