The invention discloses a large flexible printed circuit (FPC) and belongs to the technical field of flexible printed circuit manufacture. The FPC comprises a plurality of FPC units arranged on the FPC and the plurality of FPC units are arranged in a staggered mode on the large FPC page. The invention further discloses a typeset method of manufacturing the FPC. The plurality of FPC units are arranged in the staggered mode on the large FPC page. According to staggered arrangement of the FPC units, stress generated is dispersed so that stress intensity is lessened, a bending ratio is reduced and yield in the process of the large FPC manufacturing and large FPC blanking is improved. The typeset method of manufacturing the FPC can be used in the manufacturing process of the FPC.

The invention discloses a method of reducing land occupation of a reactive compensation device layout. Reactive compensation devices are arranged in power distribution intervals of a transformer substation. Each active compensation device comprises a capacitor bank and a reactor group. At least one power distribution interval of one group of main transformers of the transformer substation is designed to be an interchange interval where not only the capacitor bank but also the reactor group can be arranged. During the operation process of the transformer substation, according to operation requirements, the capacitor bank and the reactor group are interchanged in the interchange interval. The method has the advantages that each group of main transformers can save an interval occupation of one low-voltage power distribution unit and reactive compensation equipment, occupation of four intervals can be saved if the number of groups of main transformers of the transformer substation is four, each group of main transformers can save one interval of switch equipment investment, and four intervals of switch equipment investment can be saved if the transformer substation is provided with four groups of main transformers.

A fuel cell stack includes a stack body formed by stacking a plurality of power generation cells. At opposite ends of the stack body in a stacking direction, end plates are provided. A second power collecting terminal protrudes outwardly from the end plate. One end of a bus bar is electrically connected to the second power collecting terminal such that the bus bar extends along an end plate surface intersecting the second power collecting terminal. A high voltage cable is connected to the other end of the bus bar. The high voltage cable is drawn toward the end plate.

One end of the shuttle plate is installed in the guide groove, and the other end is equipped with a mold head. Positioning pins are installed on the clamping mold. The invention has a simple, compact and reasonable structure; it can adapt to the simultaneous molding of honeycomb paperboards and paper cores of various specifications, and can be made into multi-layer honeycomb paper cores after cutting; it occupies a small area, has low manufacturing cost, no pollution, no noise, and can One person operates multiple paper core forming machines.

The robot controller is connected with the industrial robot by connecting cables. The robot controller has a case for storing the actuator controller. One side of the box has a stepped portion. The stepped portion has a connection portion, and the connection cable is extended along the one side surface in a state where the connection cable is arranged on the one side surface. A connection cable is connected to the connection part. Therefore, the robot controller can save space.

The invention provides a unipolar current cross-connected three-level sub-module, and belongs to the field of a power electronic technology and power transmission and distribution. The sub-module comprises a first DC capacitor, a second DC capacitor, a first fully-controlled power electronic switch device, a second fully-controlled power electronic switch device, a fully-controlled power electronic switch unit, a first diode, a second diode and a diode unit; and two structures of the unipolar current cross-connected three-level sub-module with forward current outflow and the unipolar current cross-connected three-level sub-module with forward current inflow are provided according to different forward current directions. According to the unipolar current cross-connected three-level sub-module provided by the invention, the quantity of output levels of the sub-module can be improved when DC fault ride-through of a modular multilevel converter is achieved; the power density of the sub-module is improved; the cost is reduced; and auxiliary drive equipment and the spatial volume are saved.

The invention discloses a box-type transformer facilitating maintenance of an internal device. The box-type transformer comprises a box, a servo motor, a transformer body and a cooling fan, wherein aside plate is arranged on one side face of the box, a first sealing door is installed at one end of a motor shaft, a lower corner of a second sealing door is connected with the side plate through a movable shaft, the other end of the motor shaft is sleeved with a first gear, a second gear is connected with a third gear through a chain, a connecting shaft penetrates through the third gear, the outer side of the connecting shaft is sleeved with a sleeve block, a fixed cylinder is fixed to the top of the transformer body, the top of a connecting rod is connected with a line storage box through aconnecting block, and a fixed rod is fixed to one side of the line storage box. Through the box-type transformer facilitating maintenance of the internal device, the transformer body in the box can beautomatically driven to slide out, the situation that a large amount of manpower needs to be consumed in a maintenance process is avoided, and the open sealing doors cannot occupy outside space.

An object of the present invention is to provide a refrigerator capable of suppressing an unnecessary space waste. The refrigerator of the present invention comprises: an operation panel (20) having afront surface member (21); a control substrate (31) provided on the back side of the front surface member (21); a substrate housing portion (41) for housing the control substrate (31) and fixing thefront surface member (21); and a heat insulating box (10) provided with a foam heat insulating material and a vacuum heat insulating material (50) between an outer case (11) and an inner case (12) forconfiguring the operation panel (20) on a side wall (12a) of the inner case (12), wherein there is no foam heat insulating material present at least near the center in the gap between the vacuum heatinsulating material (50) or the outer case (11) and the bottom of the substrate housing portion (41).

An underbody panel for a motor vehicle is composed of a lightweight sandwich material and is configured as a single part with at least one continuous folding connection (12) that extends in a transverse direction of the underbody panel and is arranged between first and second portions of the underbody panel (14).
