| 20090251026 | Piezo Electric Linear Motor - The present invention relates to a piezoelectric linear motor that can make relatively low abrasion and accurate linear movement since stationary AC voltages are applied to two piezoelectric elements with a phase difference. The present invention provides a piezoelectric linear motor, comprising: a piezoelectric substrate having a first piezoelectric element and a second piezoelectric element, wherein AC voltages are applied to the first and second piezoelectric elements with a phase difference; a metallic elastic body having first and second elastic bodies coupled to the piezoelectric elements and a central protrusion protruded at the central portion connecting the first and second elastic bodies, wherein the central protrusion oscillates elliptically during an application of the voltage; and a mover brought into contact with the central protrusion of the metallic elastic body for a linear movement, and wherein the movement of the mover is orthogonal to the central protrusion. | 10-08-2009 |

| 20090140626 | VACUUM CHANNEL TRANSISTOR AND MANUFACTURING METHOD THEREOF - Disclosed are a vacuum channel transistor including a planar cathode layer formed of a material having a low work function or a planar cathode layer including a heat resistant layer formed of a material having a low work function, and a manufacturing method of the same. In the vacuum channel transistor, electrons can be emitted even when a low voltage is applied to a gate layer, a voltage of an anode layer has a small influence on electron emission of a cathode layer, and instability of emission current is obviated. Accordingly, high efficiency and a long lifespan can be achieved, and thus operational stability is secured. | 06-04-2009 |

| 20110255848 | APPARATUS AND METHOD FOR CONTROLLING HEATING LAMP OF RAPID HEAT TREATMENT EQUIPMENT - The method of the present invention for controlling a heating lamp of rapid heat treatment equipment comprises: a step wherein a heating lamp group is divided into a plurality of subgroups to determine graphical data regarding input voltage versus the reference input current that is applied to the subgroups uniformly; a step wherein actual input current respectively applied to each group is measured to obtain graphical data regarding input voltage versus actual input current; a step wherein a difference value for calibration of each subgroup is obtained from the difference between the reference input current and the actual input current; and a step wherein the difference value for calibration is reflected to apply a voltage to said subgroup individually. According to the present invention, substrate heating takes place uniformly because differences of calibration are reflected in actual input current to apply a voltage to a subgroup. | 10-20-2011 |
