Title: Apparatus for manufacturing information recording disc
Inventor: HIRANO SHIZUO
IPC: B29K101/10
Filed: 1983-12-06
Abstract: PURPOSE:To secure the transfer of signals onto a resin layer from a stamper by reducing pressure down to a specified vacuum between a base and a transparent substrate placed on the stamper through a liquid radiation hardening resin to press the transparent substrate on the stamper depending on a atm. difference. CONSTITUTION:As a photopolymer 2P is filled between a stamper 15 and substrate 43, a circular seal 47 lowers together with a vacuum pad 38 to the outer rim of the substrate 43 while maintaining the airtightness of a circular groove 33a along the outermost circumference of the stamper 15. Then, as the circular grooves 33a and 33b are reduced in pressure through communicating paths 34a and 34b, a photopolymer resin layer becomes vacuum to have the substrate 43 pressed on the stamper 15 at the atmospheric pressure. Thus, bubbles forced into the resin layer are pushed toward the inner and outer circumference of the substrate 43 and removed. At the same time, the thickness of the resin layer can be kept evenly below about 10mum to ensure the transfer.

CONSTITUTION: A sample injector 2 supplies a constant amt. of a dye soln. to a column 1 from one end (a) thereof and a solvent supply pump 3 supplies a solvent to the column 1 at constant supply speed from one end (a) thereof. An absorptiometer 5 measures the concn. of the soln. continuously flowing out of the other end (b) of the column 1.

The calibration curve can be easily calculated from several kinds of samples with known concns. By this constitution, operation becomes easy and rapid and this measuring method becomes suitable for automation.
