Title: Supplying method of gas for excimer laser device
Inventor: ISHIHARA TAKANOBU
IPC: H01S3/225
Filed: 1993-12-24
Abstract: PURPOSE:To obtain a stable laser output even when a laser is stopped for a long period, by calculating the amount of injection of a mixed gas of a noble gas and a buffer gas on the basis of a calculated oscillation stop time and by injecting the mixed gas by the calculated amount of injection before oscillation of the laser. CONSTITUTION:When an oscillation stop time T exceeds a lower-limit time Tt for output correction, a Kr-Ne mixed gas is injected to compensate lowering of a laser output. A controller checks the presence or absence of a gas replacement request signal first, and when a request for replacement is present, it compares a power lock charging voltage Vp with a Kr-Ne mixed gas injection charging voltage Vc. When this comparison shows that Vp<=Vc, gas replacement is executed with the same gas composition as that in the previous gas replacement. When Vp>Vc, however, the gas replacement is executed with the gas composition obtained by changing a filling pressure of the Kr-Ne mixed gas in accordance with DELTAV (Vp-Vc). In other words, the gas replacement is executed with the filling pressure of the Kr-Ne mixed gas increased as the value of DELTAV increases.

Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To facilitate the attachment to and detachment from a form and prevent a product from being damaged by a method wherein a positioning mechanism, which is arranged normal to a partitioning plate, consists of a downward groove slidably fitting to guide pins vertically arranged in a row longitudinally on the top surface of the reinforcing member of a form and a biforked positioning block, which can pivot to the groove and is formed at the low end part under the condition that the interval between the forks is broader than the outer diameter of the guide pin. SOLUTION: After the reduction of the width between partitioning plates 2 and the formation of a square box-like space by closing a groove 8a through the pivoting of the lever 10c of the block 10 in a guide part 8, the partitioning plate 2 are conveyed with a crane to the desired spots of a form 1. By lowering the partitioning plates 2, a guide pin 1b fits to a space formed by the side walls of the groove 8a of a positioning mechanism and a pair of projecting parts 10b and 10b of the block 10, resulting in inserting the tip of a fixing bolt 9 in the recessed part 1c of the form 1 so as to be clampingly fixed. By actuating a cylinder backwards, a packing is brought into close contact with the inner surface of the form 1 so as to fill up a gap between the bottom plate and the side plate of the form in order to pour stock slurry in the form for forming and setting the slurry. Thus, the easy positioning and fixing of the partitioning plate can be realized, a semiplastic body is prevented from being damaged and the stock slurry can be prevented from leaking.
