Title: Pressure variable adsorption separation
Inventor: HORII YUJI
IPC: B01D53/04
Filed: 1991-10-08
Abstract: PURPOSE:To effectively decrease the quantity of cleaning gas required in a cleaning process by changing the pressure of cleaning gas flowing from a product gas storage tank to an adsorber on a cleaning process by the operation of a valve on the outlet side of the adsorber. CONSTITUTION:A valve 11 is opened with a valve 15 located on the outlet side of cleaning gas of an adsorber 3a being closed (gas feed operation). Thereby gaseous CO with high pressure and high concentration in a product gas storage tank 5 flows into the adsorption tower 3a under about the atmospheric conditions to increase the pressure in the adsorption tower 3a. In a state where this pressure is equal to that in the product storage tank 5, the flow of the gaseous CO is stopped. When the gas flow is stopped, the valve 11 is opened and the valve 15 is closed this time (gas discharge operation). Thereby gas accumulated in the adsorption tower 3a is discharged from it to an adsorption tower 3b to decompress the adsorption tower 3a. When the pressure of the adsorption tower 3a is about atmospheric one, gas discharge is stopped. At this time, the above gas feed operation is performed again.

Title: Power supply apparatus
Inventor: MURATA NORITAKA
IPC: H02M3/28
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To obtain a power supply apparatus whose power conversion efficiency can be enhanced by a method wherein a control circuit sets a pulse voltage level on the basis of the output voltage of a voltage adjusting circuit. SOLUTION: When pulses at a constant frequency are supplied to the gate of a MOSFET Q1 at a power-supply apparatus, a drain current becomes the product of a transfer conductance multiplied by a driving voltage. Then, a delay circuit 12 in a load-current detection circuit 10 delays a load-current signal indicating the magnitude of a current on the basis of a drain current to be input from a load-current-signal input terminal 11 so that a driving voltage by which the drain current becomes a minimum current is given to the MOSFET Q1. Then, a comparison circuit 13 compares a load-current signal with the delayed load-current signal.  A voltage adjusting circuit 20 adjusts an output voltage so as to become low on the basis of a comparison result when the level of a present load-current signal is lower than the level of the delayed load-current signal, and it adjusts the output voltage so as to become high when the level is high. As a result, the power conversion efficiency of the power- supply apparatus can be enhanced.
