A liquid crystal alignment agent having polyamic acid or polyimide prepared using the amine compound of the present invention enables a liquid crystal alignment film and a liquid crystal display device having an excellent thermal stability even after forming the liquid crystal alignment film, and expressing high alignment and stability even after an ultraviolet ray irradiation.

The invention discloses a flowerpot and flower and plant matrix separating device and belongs to the field of automatic equipment for facility agriculture. The flowerpot and flower and plant matrix separating device comprises an equal-separation-distance conveyor, a potted flower conveyor, a rodless air cylinder, a potted flower pushing plate, a potted flower rubbing channel and potted flowers. The potted flowers are conveyed to working positions through a conveyor and are moved to the equal-separation-distance conveyor through the potted flower rubbing channel under the pushing of the potted flower pushing plate, the potted flower pushing plate is driven by the rodless air cylinder, two sides of the potted flower rubbing channel have a certain radian, flowerpots and the matrixes in the flowerpots are extruded in the potted flower passing process to weaken the bonding force between the flowerpots and the matrix, and accordingly the flowerpot and matrix separating process is achieved. The flowerpot and flower and plant matrix separating device is one important portion of an automatic transplanting production line, flowerpot and matrix separation can be achieved in a rubbing-extruding mode, and it can be ensured that the flowerpots and the matrixes are complete after separation and the matrixes can be smoothly taken out of the flowerpots for transplanting operation.

The invention relates to a mechanism for checking out unqualified products from circular annular parts. The mechanism is characterized by comprising a bottom plate, a bracket, an air cylinder, a rack, a gear, an overturn plate and a rotating shaft; the bracket is fixed on the bottom plate; an unqualified product dropping channel is arranged on the bottom plate; the rotating shaft is supported on the bracket; one end of the rotating shaft is in keyed joint with the overturn plate, and the other end of the rotating shaft is connected with the gear; the gear is meshed with the rack; one end of the rack is connected with a piston rod of the air cylinder. The mechanism has the benefit effects: the mechanism can be used in coordination with an automatic detecting production line to detect external diameters, internal diameters, thicknesses and weights item by item, and then checks out the unqualified products automatically. The automatic detecting production line is further completed, and automatic movement, arrangement and item-by-item detection on the external diameters, the internal diameters, the thicknesses and the weights are realized. The mechanism is driven by pneumatic elements, automatic movement and inspection are achieved, the degree of automation is high, the detection precision is high, and automatic screening and arrangement are achieved.

The invention discloses a communication device applied to an intelligent network charge interactive terminal. The communication device comprises an upper interface, a lower interface, an own data storage unit, a sub-node data storage unit and a node register, and further comprises an index information register, wherein the node register is used for collecting the data in the data storage units corresponding to this communication device and all lower communication devices therebelow; or the node register can collect the index information of the data through the internal index information register; the internal structures of the communication devices are consistent when the communication devices communicate with the upper or the lower, the data content corresponding to the node register is uploaded through the upper interface, and the transmission can be performed according to the required order of the upper communication device in the uploading. Therefore, an operation of independently performing master-slave configuration on each node according to a hierarchical relation between the nodes is unnecessary, the workload of the networking configuration is greatly reduced, and the communication device can be high-flexibly applied to various distribution automation fields.
