The present invention relates to technology for manufacturing electrical steel sheets having excellent magnetic properties through the control of a hot-rolled texture using the phase transformation of steel. More particularly, it relates to a non-oriented electrical steel sheet that has reduced iron loss and increased magnetic flux density by controlling alloy component elements and optimizing hot-rolling conditions, even though hot-rolled sheet annealing is not carried out, as well as a manufacturing method thereof. More specifically, the invention provides a non-oriented electrical steel sheet which has excellent magnetic properties while hot-rolled sheet annealing can be omitted, the steel sheet being comprised of 0.005 wt % or less of C, 1.0-3.0 w % of Si, 0.1-2.0 wt % of Mn, 0.1 wt % or less of P, 0.1-1.5 wt % of Al, and a remainder of Fe and other inevitable impurities, in which the relationship between the elements Mn and Al satisfies an equation of −0.2

A cleaning robot having an exhaust air feedback function can utilize the vacuum suction force generated by a suction motor as well as spray exhaust air onto the surface to be cleaned by circulating the air using the suction motor, thereby improving foreign material removal efficiency. The cleaning robot includes a suction unit, a suction motor for drawing in foreign materials from the surface to be cleaned, along with air, through the suction unit, a dust collector for capturing the foreign materials, so that the air is exhausted through the suction motor, and an exhaust air feedback unit for feeding the air. The cleaning robot also includes a spray nozzle unit inserted into the suction unit and placed on the leading end of the suction unit, the spray nozzle unit spraying the air fed by the exhaust air feedback unit, to the surface to be cleaned.

Disclosed is a method of forming a pattern in a semiconductor device. A first mask pattern to form dense lines and a second mask pattern to form spaces (parts where ends of lines are opposite to each other) are used when double patterning is applied to a photolithography process to form a line and space pattern on a semiconductor substrate. Therefore, when the line and space pattern is formed, a fine pattern may be formed without generating a bridge at parts where ends of lines are opposite to each other.

The system for performing wafer processing comprises an in-line system comprising a stepper for performing alignment and photo-exposure of a wafer and a spinner, in-line connected to the stepper, for performing coating and development of the wafer, and an overlay measurement device, in-line connected to the spinner, for automatically measuring an overlay accuracy of the wafer after wafer development is completed by the spinner.
摘要:
An exemplary power supply provides low power dissipation in standby mode by disabling the start-up circuit and by implementing variable frequency operation independent of the feedback signal. A standby mode detection circuit automatically implements the variable frequency operation, and an under voltage lockout signal implements the start-up circuit disable. Once the start time expires or when feedback control enables, the start-up circuit is disabled so that it dissipates negligible power. A voltage controlled oscillator responsive to the rectified DC line voltage provides for variable frequency operation in standby mode. The frequency output of the VCO is inversely proportional to the line voltage—as line voltage increases the switching frequency decreases, which decreases the output power.
