摘要： An electric vehicle includes a device which determines, on the basis of the gradient of a road surface, a target acceleration of the vehicle in the case where the operational states of an accelerator (gas) pedal and a brake pedal of the vehicle are an OFF state when the vehicle is traveling on a down-slope road, a device which determines the correction amount of a regenerative torque for bringing the actual acceleration of the vehicle close to the target acceleration, a device which determines a basic target torque of an electric motor, which becomes a regenerative torque when the operational state of the accelerator (gas) pedal is the OFF state, on the basis of the operational state of the accelerator (gas) pedal, and a device which determines a target torque by correcting the basic target torque on the basis of at least the aforesaid correction amount. The output torque of the electric motor is controlled to the determined target torque. Thus, when the electric vehicle travels on the down-slope road, the regenerative operation of the electric motor is accomplished such that an acceleration suited to the gradient of the road surface can be generated in the vehicle while minimizing the influences of disturbance factors.

摘要： An apparatus for precisely and adequately filling each of upper and lower flask bodies with molding sand equipped with upper and lower compressed air jet mechanisms (which fluidize molding sand at side and lower parts in a substantially horizontal part of each of upper and lower blow heads) and upper and lower guide members (which guide molding sand so as to disperse it toward the entire area of end openings of the blow heads after the molding sand in each blow head has first been focused on the blow head's central part) projectingly provided in the upper and lower blow heads, and a blow head for use in such an apparatus. Thus, the molding sand in the upper and lower blow heads is almost entirely fluidized by jetting compressed air from the upper and lower jet mechanisms when molding sand is blow-squeezed into upper and lower flask bodies. As a result, the molding sand is blown into the upper and lower flask bodies while it is dispersed toward the entire area of the end openings of the upper and lower blow heads.
