Patent JP-H0312913-A (JP)
Title: Light source device for exposure and alignment of optical axis in exposure device
Inventor: ISHIBASHI YORIYUKI
IPC: H01L21/027
Filed: 1989-06-09
Abstract: PURPOSE:To obtain stable alignment of optical axes with high accuracy on the occasion of performing optical alignment with respective optical system elements that are incorporated into an exposure device by providing the 1st light source which outputs invisible ray beams for exposure and the 2nd light source which outputs visible ray laser beams having the same optical axes as those of the invisible ray beams. CONSTITUTION:Visible ray laser beams 14 which are outputted from a visible ray laser light source 12 are outputted after passing through the same axes as those 15 of excimer laser beams 13 which are outputted from an excimer laser light source 11. When the alignment operations of positions and optical axes between a light source device 10 and other optical system are performed, the above operations are achieved by operating only visible ray laser light source 12 and are performed by using the visible ray laser beams 14 that are outputted from the above light source. Highly accurate alignment of the positions and optical axes are thus performed without using invisible rays; besides, the excimer laser beams 13, i. e., ultraviolet rays that are harmful to eyes.

Title: Displacement correcting method for nc machine tool
Inventor: TSUTSUI KATSUNORI
IPC: B23Q15/18
Filed: 1992-05-16
Abstract: PURPOSE:To enhance the processing efficiency of an NC machine tool by performing measuring conforming to the measuring movement command with a proper frequency. CONSTITUTION:The number of times (requisite) of measuring movement commands which is required to perform measuring actually in response to the measuring movement command is set so as to enlarge each time measuring takes place. The number of times of measuring movement commands is counted each time the measuring movement command is issued (Step 106), and judgement is made whether the obtained number is the abovementioned requisite number (Step 110), and if yes, measuring is executed actually (Step 108). The number of times of commands required to make measuring movement is so set as enlarging with actual conduction of the measuring movement, and the next measuring movement must have a greater number of times of commands. Therefore, the frequency where the measurement is actually executed in response to the measuring movement command becomes lower with proceeding of measurements.

In normal motor operation, both bidirectional rectifying elements FLS1 and FLS2 are conducted and the current is caused to flow to a main winding 11, a capacitor 13 for operation and an auxiliary winding 12. Then, revolution is obtained. At the time of braking, the both bidirectional rectifying elements FLS1 and FLS2 are caused to be not-conductive and a rectifying element TH1 is conducted. Then, in a condition that the capacitor 13 for operation and auxiliary winding 12 are separated from the main winding 11, the pulsating current to be half rectified by the rectifying element TH1 is caused to flow to the main winding 11. Then, a brake torque characteristic is obtained. Since there is no torque generation in a regular direction, the electro-magnetic brake can be loaded regardless of brake timing.
