    摘要： The present invention relates to a BOD analyzer comprising a microbe sensor containing an oxygen electrode and a microbe membrane. The microbe membrane is made by immobilizing microorganisms belonging to the genus Klebsiella in membrane. Specifically, the present invention relates to a BOD analyzer comprising flow cell equipped with a microbe sensor containing an oxygen electrode and a microbe membrane; and a liquid passage which is connected with the entrance of the flow cell and which is equipped with an outlet. The microbe membrane is made by immobilizing microorganisms belonging to Klebsiella oxytoca 12092 strain in a porous hydrophilic membrane having an average pore size of 0.65-3 .mu.m in diameter by using at least one gelating agent selected from the group consisting of alginic acid or salts thereof, agar, gellan gum, xanthane gum, gelatine, carageenan, locust bean gum, methylcellulose, pectin, and pullulan. The present invention also relates to improved methods of analyzing BOD by using the BOD analyzer.

    摘要： A novel foodstuff is produced by reacting a milk-coagulating enzyme which is produced by a milk-coagulating enzyme-producing microorganism belonging to genus Aspergillus, genus Mucor, or genus Rhizopus and which exhibits a milk-coagulating activity (A) and a protease activity (B) such that the ratio of (A)/(B) is larger than 0.1, with soymilk thereby inducing coagulation, and collecting a resulting coagulated material. The novel foodstuffs produced have the benefit of lacking the bitterness and astringency common to soybean, abounds in emulsifying activity, exhibit a high water-retention property, and are smoothly agreeable to the taste. Thus, they have extensive utility as substitutes for raw materials in conventional processed foods. They are especially suitable for use as raw materials for emulsifiable foods.

    摘要： In a sulfur dioxide detector using SO.sub.2 -oxidant microbes, a bio-membrane is located at one end of an oxygen concentration sensor, the bio-membrane containing the SO.sub.2 -oxidant microbes between an immobilized membrane and a gas permeable membrane. The sensor has an electrode in contact with the immobilized membrane. A dish-shaped or frusto-conical cell has an open end which is in contact with the gas permeable membrane so that SO.sub.2 -laden solution supplied to the cell causes sulfurous acid to oxidize to sulfuric acid as the SO.sub.2 permeates through the bio-membrane so as to change an output from the sensor. An inlet and outlet hole are formed on a sidewall of the cell. The outlet hole is located to be always directly above the inlet hole so as to drain foam formed when the SO.sub.2 -laden solution is supplied to the cell through the inlet hole and drained from the outlet hole.

    摘要： A switching power supply device includes a transformer for voltage conversion, a synchronous rectification MOS transistor, and a secondary side control circuit. The synchronous rectification MOS transistor is connected in series to a secondary side coil of the transformer. The secondary side control circuit performs on/off control of the synchronous rectification MOS transistor based on a drain voltage of the synchronous rectification MOS transistor. The secondary side control circuit includes a peak period detection circuit and a determination reference voltage generation circuit. The peak period detection circuit detects a peak period of the drain voltage. The determination reference voltage generation circuit generates a reference voltage to be used as a reference for determining the peak period based on a voltage in the peak period. The peak period detection circuit detects the peak period based on the drain voltage and on the reference voltage.
