Abstract: Provided is a method of producing a catalyst or adsorbent carrier and a catalyst or adsorbent carrier which can enhance a catalyst or adsorbent function, and prevent fall-off of catalyst particles or adsorbent particles. The surface of a metal base material made of aluminum or an aluminum alloy is subjected to an etching process using an etchant containing iron chloride and an oxide to convert the surface to an uneven and rough surface. The uneven and rough surface of the metal base material is subjected to an anodizing process to form a porous coating along the uneven and rough surface. A large number of catalyst or adsorbent particles are thus carried on the surface of the metal base material on which the porous coating is formed along the uneven and rough surface.

Abstract: In order to restrain generation of a peak in the measured flow rate, a fluid control unit measures a flow rate of a fluid in a channel and outputs a signal indicating a valve operation amount of a fluid control valve obtained based on a deviation between a preset flow rate and a measured flow rate and a control coefficient, and the control coefficient for a stable state and the control coefficient for a transitional state are so set to moderate fluctuation of the valve operation amount to the deviation more in the transitional state than in the stable state. At or shortly after a timing when the stable state is switched to the transitional state, a signal is output that indicates an operation amount for a switching time calculated based on each of the operation amounts output at a plurality of timings in the stable state.
