  • Patent number: 12466746
    Abstract: A producing device includes an electrolytic bath having chambers partitioned via a cathode side diaphragm and an anode side diaphragm; and a diaphragm protecting structure for preventing damage to the cathode side diaphragm and/or the anode side diaphragm. The electrolytic bath includes a pair of cover members each including a concave portion by which the cathode chamber and the anode chamber are compartmentalized from each other; a partition wall having an opening by which the intermediate chamber is compartmentalized, the partition wall being sandwiched between the cover members via a cathode, an anode, the cathode side diaphragm, and the anode side diaphragm; and seal members, each watertightly closing a gap between the cover member and the partition wall. The diaphragm protecting structure includes protrusions formed to protrude from the seal members into the chambers beyond an edge of the concave portion or an edge of the opening.

  • Publication number: 20250145505
    Abstract: There is provided a producing device that can easily individually obtain acidic electrolyzed water, alkaline electrolyzed water, and mixed water while saving a space. A producing device includes: an electrolytic bath configured to produce acidic electrolyzed water and alkaline electrolyzed water; an adjuster configured to adjust discharge and merging of the acidic electrolyzed water and the alkaline electrolyzed water produced in the electrolytic bath; a flow rate adjuster configured to adjust flow rates of the acidic electrolyzed water and the alkaline electrolyzed water merged by the adjuster; and discharge portions capable of separately discharging the acidic electrolyzed water, the alkaline electrolyzed water, and the mixed water produced by merging the acidic electrolyzed water and the alkaline electrolyzed water.

  • Publication number: 20040001944
    Abstract: The display sheet comprises: a sheet-like member, which comprises a support, such as a sheet of paper and a plastic film, and a 30 to 500 micron thick flexible microporous suction sheet which is disposed on a back surface side of the support and in which an infinite number of fine and flexible depression pores 5 to 300 microns in diameter are formed; and a release film, which releasably covers a surface of the microporous suction sheet to protect the microporous suction sheet, is 10 to 100 micron thick and has a smooth surface.

  • Patent number: 5644549
    Abstract: An apparatus for accessing an extended data output dynamic random access memory (EDO DRAM) is disclosed. A conventional fast page mode (FPM) DRAM is converted by the present invention to conform to an EDO DRAM. The present invention comprises a conventional FPM DRAM, a read-cycle generating circuit for generating a signal that defines a read cycle, a flip-flop for latching data signals from the FPM DRAM, an output control circuit for generating a control signal to control a data switch that will pass the latched data signals. The data signals come directly from the FPM DRAM and the latched data signals come from the data switch are combined to form extended data signals coupled to a system data bus.

  • Patent number: 5640353
    Abstract: An apparatus and method for bit defect compensation is disclosed which comprises a tag address means for storing addresses of defective bits of a DRAM; a compensation data means for storing replacing bits utilized to replace the defective bits; a control circuit that provides logic and timing controls for compensation actions; and a comparator that provides comparison function between DRAM access address and addresses stored in the tag address means, and generates a compensation address to access the replacing bits in the compensation data means when necessary. The present invention provides an improved apparatus and method for compensating for the problem of bit defect, and improving the traditional fail bit memory scheme.
