  • Electromagnetic interference suppressing body having low electromagnetic transparency and reflection, and electronic device having the same
    Patent number: 6448491
    Abstract: An electromagnetic interference suppressing body is provided for suppressing electromagnetic interference by undesirable electromagnetic waves. The body includes a conductive support element and a non-conductive soft magnetic layer provided on at least one surface. The electromagnetic interference suppressing body may be used in an electronic equipment comprising a circuit board and an active element mounted on the circuit board, and is interposed between the circuit board and the active element so as to suppress the interference by an induction noise generated from the active element. The electromagnetic interference suppressing body may also be used in a hybrid integrated circuit element having an active element and a passive element mounted on a circuit board. The hybrid integrated circuit element is covered with and sealed by a non-conductive layer and the electromagnetic interference suppressing body overlying an outer surface of the non-conductive layer.

  • Device for replenishing fixing solution employed in automatic processor
    Patent number: 5150142
    Abstract: In a fixer replenishing device employed in an automatic processor, a hardening agent is diluted with water and then mixed with a fixing agent. Since the hardening agent is not directly mixed with the fixing agent, no crystals are deposited.
