A hybrid metal melting furnace uses a furnace lid to hold molten metal, while inhibiting reduction in the service life of burners of the furnace lid caused by long periods of exposure to high heat. This hybrid metal melting furnace includes a crucible for accommodating metal to be melted; and an induction coil causing induced current to flow through and heat the metal. A furnace lid which closes an opening in the crucible includes: a first furnace lid having burners for injecting flames into the crucible; and a second furnace lid which does not have the burners. When melting the metal, the first furnace lid is disposed in a position in which the opening is closed. When holding the molten metal in the crucible, the first furnace lid is removed from the opening, and the second furnace lid is disposed in the position in which the opening is closed.

Hybrid metal melting furnace

The purpose of the present invention is to provide a melting material supply apparatus which is capable of contributing to improvements in the working environment and the melting efficiency of a metal melting furnace, and which is also capable of making melting work more efficient. This melting material supply apparatus for supplying a melting material to a crucible is provided with: a melting material supply unit for supplying the melting material to the crucible; and a furnace lid for closing an opening provided in the upper part of the crucible. The furnace lid is supported in a horizontal state by a furnace lid-supporter, and is capable of being moved between a position in which the opening is closed, and a standby position located above a hood. When the furnace lid is in the standby position, the opening is open, and the melting material can be supplied into the crucible therefrom.

A motor-driven steering controller for controlling a steering wheel of a vehicle. The controller includes a steering torque controlling unit, a braking force estimating unit, a right and left braking force difference estimating unit and an assist steering torque providing unit. The steering torque controlling unit controls a steering torque on the steering wheel depending on a steering operation. The braking force estimating unit estimates braking forces to be imposed on wheels of the vehicle. The right and left braking force difference estimating unit estimates difference between the braking forces to be imposed on the right and left wheels each estimated by the braking forces estimating unit. The assist steering torque providing unit provides an assist steering torque for the steering torque controlling unit on the basis of the difference in braking force between right and left wheels estimated by the right and left braking force difference estimating unit.

An apparatus for cast-product production line includes a kneader for kneading casting sand for making mold; a mold maker for making a sand casting mold from the casting sand for making mold, the sand casting mold being provided with a molding cavity for forming a singular cast product or plural products; a molten-metal pourer for pouring molten metal into said molding cavity of the sand casting mold; and a mold disassembler for disassembling the sand casting mold having undergone molten-metal pouring. Upon disassembling the sand casting mold by the mold disassembler, the sand casting mold is disassembled in such a state that the cast product is supported by means of a cast-product supporter element.

Apparatus for cast-product production line

A vehicle steering apparatusincludes a variable gear ratio actuator, an IFS ECU, which controls the actuator, an EPS actuator, and an EPS ECU, which controls the EPS actuator. The variable gear ratio actuatorvaries the transmission ratio between a steering wheel and steered wheels. The EPS actuatorapplies an assist force that assists a steering operation. A microcomputerof the EPS actuatorincreases an inertia compensation current command Iti* (Iti**), which is a compensation component based on the differential value of a steering torque, during actuation of the variable gear ratio actuator, that is, when an ACT angle &#x3b8;ta is changed.

A control ON/OFF determination unit determines that oversteer control should be started in the case where a slip angle differential value is equal to or greater than a predetermined threshold value, the sign of the slip angle differential value is identical with the sign of a yaw rate, the sign of a steering wheel turning angle is identical with the sign of a steering wheel turning speed, and a vehicle speed is equal to or greater than a predetermined threshold value.

In an electrical powered vehicle including a control device for generating an input/output power command value for a power storage device and a control device for controlling a power conversion device and a rotating electric machine, provided separately, when there is a sudden change in the rotational speed of a rotating electric machine, the input/output power command value of a power storage device intrinsically set by an HV-ECU is corrected corresponding to the change in the rotational speed of the rotating electric machine by a control device MG-ECU detecting the rotational speed of the rotating electric machine, without having to wait for modification of the input/output power command value from the HV-ECU. Accordingly, there can be prevented excessive charging and excessive discharging of a power storage device induced by delay in modifying the input/output power command value caused by transmission delay between control devices when the rotational speed of the rotating electric machine suddenly changes.

An IFS torque compensation unit includes an oversteer IFS torque compensation gain calculation unit, which obtains a larger IFS torque compensation gain as a control target element increases during oversteer control.
