A cooling system that cools hot rolled long steel bar, provided with a plurality of chambers that are arranged along the longitudinal direction of the rolled steel bar. Each of the plurality of chambers is provided with a blow outlet that, facing from the chamber to the rolled steel bar, blows out compressed air for cooling that is introduced to the chamber from a gas inlet that is connected to the chamber; a nozzle plate having a plurality of nozzle holes that is provided at this blow outlet so as to face the rolled steel bar; a cooling water supply nozzle that supplies cooling water into the chamber; and a rectifying plate that is provided between the gas inlet and the cooling water supply nozzle, and that prevents the compressed gas for cooling that is introduced from the gas inlet from directly striking the nozzle plate. The cooling system of the present invention sprays a cooling medium that is produced by mixing the cooling water that is supplied from the cooling water supply nozzle and the compressed gas for cooling that is introduced from the gas inlet and rectified by the rectifying plate toward the rolled steel bar through the nozzle holes of the nozzle plate, and performs uniform cooling of the surfaces of the rolled steel bar.

A method of manufacturing a semiconductor integrated circuit wherein a patterned wafer polishing machine for uniformly polishing a surface by chemical mechanical polishing is utilized which is provided with a head for holding a wafer and rubbing it on an abrasive surface. A pressure plate provided with vents is held by the head body which is provided with a gas inlet and an elastic film for sealing vents is provided on the end face on the side reverse to the gas inlet side of the pressure plate. A patterned wafer is held by the head as the wafer, pressed by action of the pressure of air from the gas inlet via the elastic film is pressed mechanically by the pressure plate. The polishing surface which is a principal plane on the patterned side of the wafer is mechanochemically polished by the abrasive surface.

An electro-rheological (ER) fluid damper control system employs fuzzy logic to attain real time control in a highly responsive manner. The ER fluid damper is interposed in a vehicle between its sprung mass (vehicle body) and unsprung mass (suspension). Signals corresponding to the velocity of the sprung mass and the relative velocity between the sprung and unsprung masses are generated by pairs of accelerometers and electronic integrators. A fuzzy rule, taking into account weighted values of these input signals, is applied to the signals to determine an output value which, in turn, establishes a control signal for application to the electrodes of the ER fluid damper. As the velocity signals change, the voltage applied to the electrodes also changes, thus adjusting the fluid viscosity and mechanical responsiveness of the ER fluid damper.

An organic film removing method uses an organic film removing apparatus comprising a processing vessel defining a processing chamber, a wafer support for supporting a semiconductor wafer within the processing chamber, and a mixed gas supplier for supplying a mixed gas consisting of an alcohol or alcohols, and ozone gas or an ozone-containing gas into the processing chamber so that the mixed gas acts on an organic film pattern on the surface of the supported semiconductor wafer. The apparatus continuously supplies the mixed gas into the processing chamber at least in a period between a time immediately before mounting the semiconductor wafer on the wafer support and a time when the organic film is removed completely; conveys the semiconductor wafer into the processing chamber; supports the semiconductor wafer within the processing chamber; and heats the patterned organic film on the surface of the supported semiconductor wafer at a temperature in a range below a temperature at which substantial defects will be formed in the elements of a semiconductor device to be formed on the semiconductor wafer. This method is capable of ashing the organic film at an ashing rate equal to or higher than an ashing rate at which a known organic film removing method employing a steam-containing ozone gas ashes the organic film, and of reducing water marks as compared with the known method employing the steam-containing ozone gas.
