Abstract: An insulator according to an embodiment includes a teeth cover portion and a crossover-wire guide portion. The crossover-wire guide portion includes a plurality of guide walls, a drawing groove, a drawing path, and a crossover-wire support portion. The plurality of the guide walls separate the crossover-wire portions of the coils and are capable of guiding the crossover-wire portions in the core circumferential direction. The drawing groove penetrates through all of the plurality of the guide walls in the core radial direction. The drawing path is disposed at a position away from the drawing groove in the core circumferential direction. The crossover-wire support portion changes a direction of the crossover-wire portion of the coil drawn out from the drawing groove, to be directed to the drawing path, and supports the crossover-wire portion.

Abstract: A sensor system includes a LiDAR and a dirt determination unit. The LiDAR includes a light emitting unit configured to emit light to a detection range via a transmissive part configured to transmit light, a light receiving unit configured to receive light emitted from the light emitting unit and reflected by hitting at an object, and a point group information output unit configured to output point group information comprising position information on the object and distance information to the object, based on the light received by the light receiving unit. The dirt determination unit is configured to detect dirt attached to the transmissive part, based on the point group information. The detection range to which the light emitting unit emits light is divided into a plurality of regions including a first region and a second region different from the first region.

Abstract: An improved electrolytic cell of simple construction capable of satisfactorily producing periodates comprises a plurality of cathodes mounted vertically in parallel to the long sides of a cell body and spaced at equal intervals from each other, a plurality of open anodic compartment boxes with plate separators adapted to maintain the equal intervals, one or more anodes inserted in the compartment boxes, a plurality of PVC diaphragms mounted on both sides of the anodic compartment boxes in parallel to the cathodes, an anolyte inlet mounted in the lower part of the anodic compartment boxes and an anolyte outlet mounted in the upper part of the opposite side of the anodic compartment boxes, a cell cover provided with air intake holes and cell gas exhaust pipes, and perforated PVC lids for the cathodic compartments positioned between the cell cover and the upper level of the catholyte.
