Abstract: PURPOSE:To manufacture high-purity nitrogen gas and liquid nitrogen efficiently by a method wherein low-temperature liquefied gas in a fractionating tower is introduced from the upper part of the tower into an adsorbing tower to take out one portion of the liquefied gas, from which impurities are removed, to the outside of a system while the balance of the liquefied gas is extracted out of the system after liquefying it by heat exchange between liquefied air, refined in the fractionating tower. CONSTITUTION:Compressed and cooled stock air gas is introduced into the lower part of a fractionating tower 1 and ascending gas is liquefied by a heat exchanger 2 to obtain circulating liquid while the circulating liquid is contacted with the ascending gas in tray steps 3 whereby nitrogan is separated and refined in the upper part of the fractionating tower 1. The nitrogen gas is introduced into an adsorbing tower 22 through a conduit 200. The conduit 200 and the adsorbing tower 22 are cooled to a low temperature previously and, therefore, the minute amount of impurities is adsorbed to and removed by an adsorbent whereby the nitrogen gas, higher in purity, is obtained and is introduced out of the adsorbing tower 22 through another conduit 201. Further, fine dust is removed by a filter 23 and, thereafter, the nitrogen gas is introduced into the heat exchanger 2 through the other conduit 202. The refined high-purity nitrogen gas is extracted out of a system through the other conduit 202 while the high-purity liquid nitrogen is extracted out of the system through the other conduit 104.

Abstract: PURPOSE:To obtain a read picture with a prescribed density at each reader by connecting a signal circuit side of a capacitor interconnecting an image sensor and the signal circuit once to ground to bring a picture signal level at that point of time to a zero level and reading a picture signal of an original picture. CONSTITUTION:When a voltage of a picture signal Vc is a voltage vd and a pulse of a DC recovery control signal D is outputted, a switch circuit 3 is closed. Thus, a side of a capacitor C at a differential amplifier circuit 2 connects to ground and the voltage vd is stored in the capacitor C. When the picture signal Vc of the original picture is outputted at a voltage vr, the picture signal Vc is inputted to a noninverting input of the differential amplifier circuit 2 via the capacitor C. Thus, the voltage vd of the picture signal Vc is shifted to a dark level to recover the DC level. Thus, a picture signal Vc' subject to DC recovery is amplified by the differential amplifier circuit 2 and inputted to an A/D converter circuit 5 and a peak hold circuit 4.
