  • Coated steel sheet and method for manufacturing the same
    Patent number: 6610422
    Abstract: The method for manufacturing coated steel sheet has the steps of: immersing a steel sheet in a hot-dip coating bath to form an Al—Zn base coating layer containing 20 to 95 mass % Al on the steel sheet, forming a passivated layer on the coating layer; and applying thermal history to the coating layer. The thermal history is applied immediately after the steel sheet left the hot-dip coating bath or in a temperature range of from T(° C.) between 130° C. and 300° C. to 100° C.

  • Electric double-layer capacitor and method of making a separator therefor
    Patent number: 6190501
    Abstract: An electric double-layer capacitor includes a casing, a pair of porous electrodes disposed within the casing, a permeable separator sandwiched between both the porous electrodes, and an electrolytic liquid formed of an organic solvent, injected into the casing and permeating the porous electrodes and the separator. The separator is formed from an aggregate of cellulose fiber having a surface modified by an organic solvent thereby. A method of making a separator for an electric double-layer capacitor includes producing a cellulose fiber aggregate, forming a sheet of the cellulose fiber aggregate, modifying a surface of the cellulose fiber aggregate sheet by immersing the sheet in an organic solvent for a predetermined time period, drying the modified sheet, and cutting the dried sheets to form the separator of a desired size and shape. The cellulose fiber aggregate sheet may also be pretreated by immersing the sheet in an amphipathic solvent.

  • Method of controlling proliferation of aerobe
    Patent number: 6127167
    Abstract: Disclosed herein is a method of controlling the proliferation of an aerobe, in which in the continuous culture of the aerobe by supplying a substrate and oxygen to a culture tank of the aerobe to cause the aerobe to decompose the substrate, the proliferation of the aerobe is inhibited while retaining the substrate-decomposing activity inherent in the aerobe. An oxidation-reduction substance which is reduced by electrons donated by an electron transport system of the aerobe and oxidized by oxygen supplied to the culture tank is caused to coexist with the aerobe in the culture tank.
