摘要:
A metal-impregnated refractory product of this invention has high slag attack, gas attack, and spalling resistances and is used in various types of molten metal treatment vessels. A material of refractory particles mainly consisting of MgO or Al.sub.2 O.sub.3 is formed and heated by a suitable method to obtain a porous material body containing at least 4 vol % of open pores. A metal or an alloy mainly consisting of at least one type of a metal selected from the group consisting of iron, chromium, and nickel is impregnated in the porous material body at a ratio of 25 vol % or more of the open pores. The metal is filled in pores present in a region from the surface to at least a predetermined depth. The metal-impregnated refractory product can withstand various high-temperature damages and can be stably used over a long time period.

A power steering system makes use of an electric motor to produce an auxiliary torque added to the torque which is applied to the steering wheel of a vehicle by the driver. The system includes a motor driver for driving the motor and a motor braking circuit for braking the motor. When the torque manually applied to the steering shaft of the vehicle is greater than a predetermined reference torque, an electronic control apparatus causes the motor driver to energize the motor according to the difference between these two torques. When the former torque is less than the reference torque, the control apparatus causes the motor braking circuit to brake the motor. In this way, the torque that the driver of the vehicle must apply to steer the vehicle is maintained equal to the reference torque, irrespective of the vehicle velocity. The reference torque is set by means of a variable-resistor.
