Title: Laser oscillation device
Inventor: ISHIKAWA KEN
IPC: H01S3/042
Filed: 1978-12-25
Abstract: PURPOSE:To prevent the device body from vibrating even if a large power is impressed on excitation lamps by constructing a coolant path of a flow path which cools the laser rod and a flow path which cools in parallel and simultaneously a plurality of excitation lamps. CONSTITUTION:Cooling water which has flowed into device proper 1 from supply path 15 flows in No.1 flow path 16 and cools laser rod 10; and then it flows in two flow paths 18, 18 and the divided flows of water cool simultaneously and in parallel excitation lamps 11, 11 and then flow out of outlet 17. Since No.2 flow paths 18, 18 are connected in parallel after flow path 16 in this way, the total length of the flow paths is small and the resistance exerted on the cooling water is small. For this reason, practically no pulsation occurs in the cooling water inside the paths. Hence, even if the power to be impressed on lamps 11, 11 is increased, the cooling water is prevented from heated extremely and boiling explosively, so that device proper 1 is prevented from vibrating.

Abstract: PURPOSE:To shorten a processing time and to enable highly-precise measurement of an attitude by detecting a gradation density level on a line by a candidate point retrieving means, by connecting candidate points between lines by an attitude judging means and by detecting the gradation density level on the line thus formed. CONSTITUTION:Parallel lines Lc and Ld are set for image data on a semiconductor wafer, candidate points of a prescribed gradation density level on the lines Lc and Ld are retrieved, these candidate points are connected, and the attitude of the wafer is judged from a line between the candidate points whereon the gradation density level is invariable, out of lines between the candidate points. Accordingly, the amount of slippage can be determined in a short time irrespective of a rotational angle of the wafer. Even when a line L21 between candidate points is judged not to pass through a dicing street from noise, besides, the line passing through the dicing street can be detected from the line between candidate points which connect other candidate points c3 and d2. Accordingly, the attitude of the wafer can be measured with high precision without being affected by the noise. Moreover, a plurality of lines L21 and L23 between candidate points which pass the streets respectively are obtained from the same image data and thus the precision in the result of measurement of the attitude can be increased.
