A drive system includes a plurality of electric power devices, a drive case having a plurality of case segments which are connected to each other, each of the electric power devices being contained in one of the case segments, and a plurality of inverters, one for each of the electric power devices. The inverters are collectively attached to one of the case segments, and a flow path of a coolant for cooling the inverters is positioned between the case segment to which the inverters are attached and the inverters. Accordingly, a cooling unit which performs heat insulation and cooling between the drive system and the inverters is positioned only on the outer surface of one of the case segments and does not extend across the connection interfaces between the case segments. Therefore, the risk of leakage of the coolant into the drive case can be substantially eliminated.

A layered pad comprising a bottom impervious layer, a top layer of a fibrous high loft non woven capable of entrapping fine or coarse particles and preventing their scatter, optionally combined with a middle layer of fibers and super absorbent agent, wherein liquids pass through the top layer, become absorbed by the middle layer, and evaporate. As particles from an animal litter box or cage, shoes, metal cutting, wood shavings, and copy machines are generated, they immediately encounter the high loft non-woven top layer, which immediately immobilizes and then entraps them, preventing them from scattering. The filament count of the non-woven can be varied to design the pads to be more effective in trapping smaller or larger particles. In addition, a film of oily substance can be applied to the fibers to make them more sensitive to absorbing and entrapping extremely small particles. If absorbency is required under the high loft fibrous non-woven, a layer of absorbent material is added between the two layers. The layered pad is optionally treated with super absorbent polymer, deodorants, antibacterial agents, anti-fungal agents, and other substances depending on the use of pad.
