Abstract: An oven observing equipment capable of observing the inside of an oven turned to a high temperature precisely includes: a housing 13 having an intake part for cooling air, and a discharging part for discharging the cooling air after being used for cooling; and an imaging device 20 contained in this housing 13 near the discharge part. This imaging device 20 is composed of integrated combination of an image sensor 16; plate-like thermoelectric cooling elements 18a to 18d arranged in a state that their heat-absorbing faces surround the periphery of a body of the image sensor; thermoconductive blocks 17a to 17d embedded in the gaps between the image sensor body and the thermoelectric cooling elements 18a to 18d; and cooling fins 19a to 19d formed on the heat-radiating faces of the thermoelectric cooling elements 18a to 18d are integrated with each other.

Abstract: In a gas refining method using a PSA method, a cleaning step is divided into a preparatory cleaning step and a substantial cleaning step, and an exhaust gas (particularly a high concentration gas obtained in the latter half is effective) obtained in the substantial cleaning step is used as a gas to be admitted into an adsorption column in the preparatory cleaning step. This method is employed, for example, to refine carbon monoxide from a material gas containing carbon monoxide. Accordingly, the gas refining method using the PSA method can ensure a specified amount of collected gas product without resulting in an increase in the amount of adsorbent even if a low concentration material gas is used.
