According to one embodiment, a semiconductor memory device includes a substrate, a stacked body, a plurality of insulative separating films, a channel body, and a memory film. The stacked body includes a plurality of electrode layers and a plurality of insulating layers. The plurality of insulative separating films separates the stacked body into a plurality. The channel body extends in the stacking direction between the plurality of insulative separating films. A width of the electrode layer of a lower layer side between the insulative separating film and the memory film is greater than a width of the electrode layer of an upper layer side between the insulative separating film and the memory film. An electrical resistivity of the electrode layer is higher for the electrode layer of the lower layer side having the greater width than for the electrode layer of the upper layer side having the lesser width.

A stave cooling device includes a double drawn steel tube cast-mounted in a castable metal main body, and the double tube includes an inner tube which serves as a passage for a coolant. The inner tube of the double tube contains 0.20 to 0.38% of equivalent carbon and an outer tube of the double tube contains 0.15 to 0.25% of equivalent carbon. The outer tube has on its outer surface an alumina coating of 0.08 to 0.25 mm thick, and the main body is formed by casting a spheroidal graphite cast iron. The double tube is cast-mounted in the main body such that the double tube and the main body are not welded together.

A positioning pin is knocked onto a crankshaft of an engine and a key way is formed in a boss of a first flywheel. When an outer rotor type generator is connected with the engine, the boss of the first flywheel is fitted over the crankshaft so as to adjust the positioning pin to the key way. When an inner rotor type generator is connected with the engine, a rotor shaft on which a rotor of a generator is mounted is fitted to a second flywheel so as to adjust the positioning pin to a key way formed in the second flywheel. The ignition angle of the engine is determined by fitting the positioning pin to the key way.

In each of the soundproofed engine generators, the position at which the power generator body is coupled to the crank shaft is located at the end part on the crank shaft. In the soundproofed engine generator of the inverter type, the inverter unit is opposed to the power generator body at a position just upstream of the power generator body. Accordingly, when the inverter unit and the power generator body are removed, a continuous, long and large space for receiving the power generator body can be secured within the soundproof cover.
