In an MCM, an optical signal is conveyed by an optical waveguide disposed on a surface of a first substrate to a first optical coupler. This first optical coupler redirects the optical signal out of the plane of the optical waveguide. Then, an optical interposer guides the optical signal between the first optical coupler and a second optical coupler on a surface of a second substrate, thereby reducing spatial expansion of the optical signal between the optical couplers. Moreover, the second optical coupler redirects the optical signal into a plane of an optical waveguide disposed on a surface of the second substrate, which then conveys the optical signal.

The invention belongs to the coaling field of coke oven vehicles and especially relates to a coaling method for a 7.63m coke oven vehicle. A coal charger charges coal into a coke oven charring room through four helical coal charging devices with the same structures. The four helical coal charging devices are controlled by delay time, and coal charging time of each helical coal charging device is 85 s. First coal leveling is carried out when 85-95% of the pre-coaling amount undergoes coal charging in the coke oven charring room by the four helical coal charging devices; and second coal leveling is carried out when coal charging is completely finished. According to the invention, furnace-mouth gas and smoke leakage caused by too much pressure in the space of the furnace roof is avoided. Meanwhile, coal charging amount of a single coke oven charring room is increased, the space height of the furnace roof is reduced, the temperature of the furnace roof space is decreased, single-hole coke yield is increased, and coke output is raised.

A multi-layer hairpin type flat wire winding stator comprises a stator core and a hairpin flat wire wave winding. Stator slots are arranged in the stator core, and the hairpin flat wire wave winding is embedded in the stator slots. The hairpin flat wire wave winding comprises more than two branches. The stator slots where three-phase windings of the hairpin flat wire wave winding are located are arranged in a pairwise spaced mode and sequentially arranged. Any branch is changed to an equivalent slot of the adjacent stator slot after circling by half of layers on the circumference, and long-distance or short-distance connection is adopted when the branch is changed to the equivalent slot of the adjacent stator slot in a cross-layer mode, so that the head end and the tail end of any branch are located on the innermost layer and the outermost layer in the radial direction of the stator. Long-distance or short-distance connection occurs only when cross-layer transposition is performed to equivalent slots of adjacent stator slots, so that the head ends and the tail ends of the branches are located on the innermost layer and the outermost layer in the radial direction of an armature, and a single branch of each phase can pass through equivalent positions of all layers of all the stator slots of the phase where the single branch is located.
