Abstract: A system for rapidly producing an integrated circuit on a substrate using a curable liquid capable of solidification to form a photo-resist pattern corresponding to an artwork representation of interconnections when subjected to ultra-violet light energy operates with a processor and computer aided design software. The system includes an x-y table, an electronically erasable mask, a drawing device and a projecting system. The substrate is disposed on the x-y table. The curable liquid lies in a solidification plane on the substrate. The electronically erasable mask is an ultra-violet wavelength isolating image buffer and is electrically coupled to the processor. The drawing device may be a back lighted liquid crystal display or a high resolution cathode ray tube or an infrared diode laser raster scanner and electronically draws an image of the artwork representation for the interconnections onto the electronically erasable mask.

Abstract: A liquid stabilizing system stabilizes an internal mirror/internal resonator gas discharge laser tube assembly which has a hermetically sealed gas laser tube which includes a gas, a capillary tube, an anode, an anode end assembly, a cathode, a cathode end bell, a cathode end assembly with electrical feed-throughs for the cathode, which are coaxially disposed with a central axis, and laser mirrors, which are sealably mounted to each end of the hermetically sealed gas laser tube. The liquid stabilizing system includes a cylindrical plastic jacket and a cooling liquid. The plastic jacket has a cooling liquid inlet and a cooling liquid outlet and surrounds the hermetically sealed gas laser tube. The cylindrical cooling jacket is sealed to the hermetically sealed laser tube by O-rings which are held in place by plastic retainers. An annulus is formed between the hermetically sealed laser tube and the plastic jacket.
