Title: Method for construction of pattern
Inventor: MORITA ISAO
IPC: G03F1/00
Filed: 1980-09-02
Abstract: PURPOSE:To obtain a photomask of good accuracy by constructing patterns for a photomask using photoresist in an inert atmosphere. CONSTITUTION:After the inside of a sealed vessel 10 is evacuated to a vacuum through a vacuum exhausting valve 11, gaseous N2 is sucked through an N2 purging valve 12, whereby an inert atmosphere is created therein. The cassette 7 on the supply side of an automatic carry-in and out device, a photomask 4 using the emulsion in this cassette 7, a passage 9 for the photomask 4, a movable stage 6, the photomask 4 on the stage 6, a cassette 8 on the receiving side, and the photomask 4 in this cassette 8 exist in the inert atmosphere, and therefore, the construction of patterns is accomplished in the inert atmosphere. Since the working atmosphere is an inert atmosphere, the reaction by which the sensitivity specks produced in exposure parts are changed to silver halide is suppressed, and the degradation in dimensional accuracy owing to insufficient density after development is obviated.

Title: Mist producting device
Inventor: IKEUCHI HIROSHI
IPC: B05B1/26
Filed: 1978-10-03
Abstract: PURPOSE: The device which is capable of producing a large volume of ultrafine particle mist with the use of a small amount of low pressure compressed air by letting the injected mixed bar flows of compressed air and liquid particles impinge vigorously at the concentrating axial point of nozzle chip axial lines thereby causing secondary fining of liquid drops.  
     CONSTITUTION: Compressed air passes through respective air conduit paths 8, 8' from air feed port 6 and enters the inside of nozzle chip mounting holes 11 and is injected from an injection hole 15. On the other hand, liquid passes through respective liquid conduit paths 10, 10' from a liquid feed port 5 and enters the central holes 13 of nozzle chips 4. Here, negative pressure is produced near the outlet of the liquid feed ports 14 owing to the foregoing injection and therefore the liquid of the central holes 13 receives shearing action by the compressed air while being sucked out and becomes small particles which are then injected to the outside through the injection hole 15. The injectd liquid bar flows from the respective nozzles impinge upon each other at the point 20 and the liquid drops are further fined by the shearing action of air by the impingement of the liquid fine particles with each other and the compressed air with each other, thus they become the mist flux of ultrafine mist and when they fly for a certain degree, they stall and suspend in air.
