A gas distributor plate provided in a fluidized bed polymerization vessel which effects the gas phase polymerization of olefins, the gas distributor plate exhibiting excellent action for uniformly diffusing the gas flow in the fluidized bed zone. A gas distributor plate has a number of gas passage holes and is provided in a fluidized bed polymerization vessel which effects the gas phase polymerization of olefins, wherein when the inner radius of the straight drum portion of the polymerization vessel is denoted by 1, the holes perforated in the outer peripheral portion of the distributor plate at 0.7 to 1.0 from the center of the straight drum portion have an average diameter which is larger than the average diameter of the holes perforated in the inner peripheral portion of the distributor plate at smaller than 0.7 from said center. This makes it possible to uniformly and stably diffuse the gas flow in the fluidized bed zone in the polymerization vessel, to effectively prevent the formation of a dead zone, as well as to effectively prevent the polymer from adhering onto the wall surfaces of the polymerization vessel.

A semiconductor device includes: a semiconductor substrate in which a SiGe layer having a first width in a channel direction is embedded in a channel forming region; gate insulating film formed on the channel forming region; a gate electrode formed on the gate insulating film and having a region protruding from a forming region of the SiGe layer with a second width wider than the first width; and source/drain regions having extension regions formed on the semiconductor substrate which sandwiches the channel forming region, thereby forming a field effect transistor, wherein the extension region is apart from the SiGe layer so that a depletion layer extending from a junction surface between the extension region and the semiconductor substrate does not reach the SiGe layer.

During an operation of an engine, an input limit Swin and an output limit Swout of a battery are set to a power demand-based input limit Wp*, which depends on a power demand P*, and to an accelerator opening-based output limit Wacc, which depends on an accelerator opening Acc (steps S400 to S420). This control technique effectively prevents the battery from being frequently charged or discharged to a relatively high level of electric power within an allowable electric power range defined by the reference input limit Bwin and the reference output limit Bwout, thus restraining premature deterioration of the battery.

An ECU calculates an evaluation value decrease amount D(−) in response to a reduction of unevenness of lithium ion concentration caused by diffusion of lithium ions resulting from a lapse of one cycle time ΔT, calculates an evaluation value increase amount D(+) in response to an increase of the unevenness of the lithium ion concentration caused by discharging during a lapse of one cycle time ΔT, and calculates a present value D(N) of a battery deterioration evaluation value D due to high-rate discharging, as a previous value D(N−1)−evaluation value decrease amount D(−)+evaluation value increase amount D(+). If battery deterioration evaluation value D exceeds a predetermined target value E, the ECU sets a discharging power limit value WOUT that is a limit value of electric power to be discharged from a battery, to a value lower than a maximum value W(MAX).
