Title: Oxygen enriching method
Inventor: GERUHARUTO RAISU
IPC: C01B13/02
Filed: 1992-02-29
Abstract: PURPOSE: To improve the efficiency of enrichment of air with oxygen by cooling a portion of an gas or a production gas and re-pressurizing adsorbers by using the gas after cooled in an adsorptive alternating pressure process for the enrichment of air with oxygen using a molecular sieve zeolite in the adsorbers. CONSTITUTION: Air is made to flow into the adsorber A by being passed through a valve 11A and a product O2 is taken out via a valve 14A and a blower R. Further, the adsorber B is deaerated by the operation of a pump V via a valve 12B, and simultaneously, the adsorber C is filled with the product O2 via valves 15, 13C. Subsequently, the enrichment of air with oxygen is executed by successively proceeding to a deaerating process and a filling process for the adsorber A, the filling process and an oxygen producing process for the adsorber B and the oxygen producing process and the deaerating process for the adsorber C.  In such a process for the enrichment of air with oxygen, a piping L14 between the blower R and the valve 15 is provided with a cooling unit device C, thereby cooling a fixed quantity of O2 flowing into the adsorber deaerated through the piping L14, thus efficiency is improved.

Abstract: PURPOSE:To ensure good recording without increasing the output of a light source and at the same time to improve the S/N of reproduced light, by providing a beam splitter having different values of transmissivity to the P and S polarizations of the recording/reproducing light to an optical system. CONSTITUTION:A beam splitter 14 is set between a laser diode 1 functioning as a laser light source for recording/reproducing and a recording medium 6. When a laser beam receives P polarization, the transmissivity is set at <=50% for the P polarization component. While the transmissivity of the S polarization component is set at 100%. As a result, the >=50% laser beam is made incident to the medium 6 to ensure the satisfactory writing of information. Furthermore, the polarization component, i.e., the signal component which is turned by a Kerr effect can be led nearly 100% toward a photodetector 11. This process improves the S/N of the reproduced light.
