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 invention discloses a multi-pile bearing platform foundation based connecting structure between a fan tower drum and a pile foundation, comprising the fan tower drum, the pile foundation and a reinforced concrete bearing platform arranged at the top part of the pile foundation, wherein the bottom of the fan tower drum is embedded in the reinforced concrete bearing platform, the fan tower drumis also connected with the pile foundation through a connecting piece, and the connecting piece is in a steel structure and is provided with an I-shape cross section. In the invention, the connectingpiece is used for directly connecting the fan tower drum and the pile foundation, thereby greatly enhancing the reliability among the fan tower drum, the reinforced concrete bearing platform and the pile foundation, and the structural integrity is strengthened. The I-shape cross section connecting piece has full strength and rigidity and can entirely or partly transfer loading acting on the fan tower drum onto the pile foundation, thereby enabling loading transfer to be more direct, improving the stress condition of the reinforced concrete bearing platform and lowering the design and construction difficulties of the reinforced concrete bearing platform.

A circuit board assembly inspection method includes the following steps: measuring a geometrical characteristic value of a solder layer before soldering an electronic component to a circuit board and comparing the geometric characteristic value with a predetermined value and defining the grad of the solder layer according to a comparing result of the comparing step and performing a defective product process to the circuit board having an extremely bad solder layer, measuring a quality characteristic value of a solder joint layer after soldering the electronic component to the circuit board and comparing the quality characteristic value with a predetermined quality parameter value and then defining the grade of the solder joint layer according to a comparing result of the comparing step, manually inspecting the circuit board assembly having both an medium-grade solder layer a the poor solder joint layer.

The invention discloses a driving device. The driving device comprises a driving plate with a curved guide groove and a power device (5) driving the driving plate to move. The driving device is characterized in that the driving plate comprises a horizontal openable plate (1) and a vertical lifting plate (2), the horizontal openable plate (1) is provided with a pair of openable curved guide grooves (3) spread from the plate center to one end, the vertical lifting plate (2) is fixed below the middle of the horizontal openable plate (1) and is provided with at least one lifting curve guide groove (4) moving in the vertical direction, the openable curved guide grooves (3) are connected to a mechanism needing horizontal displacement, and the lifting curve guide grooves (4) are connected to a mechanism needing vertical displacement. The driving device can enable the mechanisms to move in the horizontal direction and the vertical direction synchronously through the power device, the number of the transmission steps of force is small, transmission is direct, delay and dis-coordination are avoided, and the efficiency is high.

The invention relates to a shedding device comprising at least one electric rotary actuator having an output shaft ( 11 ) that is designed to rotate a pinion ( 21 ) which is engaged with a rack ( 22 ), said rack being connected to a control heald ( 3 ) of a warp end ( 4 ) by means of a load transfer element ( 24 ).

The invention discloses an alcohol boiler which comprises a base and a bottle. A projecting heating cylinder for placing at least one bottle is arranged on the base panel; a heating disc is made in seal at the bottom of the heating cylinder and is connected with a temperature controller and a micro-switch. A temperature recognizing layer which can change colors along with temperature changes is made on the surface of the bottle. The temperature controller is arranged in match on the bottom surface of the heating disc and the micro-switch is fixed on the base. The bottom surface of the base is provided in match with a base cover. Liquid water which is adopted to be a heat transfer carrier is mild in temperature rising and even in heating. A heating plate is directly arranged in match at the bottom of the heating cylinder on the base, helping reduce energy consumption. A safety switch is arranged to ensure the boiler to run normally with high operation safety. The temperature recognizing layer made on the surface of the bottle can change colors along with temperature changes; therefore the temperature of an object being heated can be observed at any time and be displayed in lively effect. A sheet metal is sealed in the bottom surface of the bottle, helping improve the high efficiency of heat transfer and facilitate cleaning operations in the cavity of the bottle.

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.
