  • Patent number: 7719689
    Abstract: There is provided a system always capable of detecting AE/ultrasound received by an FBG, even when the FBG receives a change in temperature or strain and the Bragg wavelength is fluctuated. In the AE/ultrasound detection system, the reflected light from the FBG is caused to enter a Fabry-Perot filter having an FSR equal to or greater than the reflection wavelength band of the FBG. A change in the intensity of the transmitted light corresponds to the AE/ultrasound received by the FBG. Alternatively, the reflected light from FBG is caused to enter two Fabry-Perot filters having an FSR equal to or greater than the reflection wavelength band of the FBG and having the filter-transmittance peak wavelengths different from each other by FSR/4. The intensity of the transmitted light from each of the two Fabry-Perot filters is converted into a voltage signal, and the individual signals are subjected to addition and subtraction processes.

  • Patent number: 6800227
    Abstract: Using a new molded foaming apparatus wherein chambers 13 and 14, independent from a cavity 4, are formed at the rear sides of a set of dies 2 and 3 for molding a molded foam product, so as to supply such utility fluid as air and steam to the cavity 4 through first openings 30 independently from the chambers 13 and 14, various problems created when forming vent holes are fundamentally solved, and at the same time dispersion of filling density to be caused by not forming vent holes is prevented by supplying the material beads to the cavity 4 while maintaining the pressure in the cavity 4 at a predetermined minus pressure with respect to the pressure in the material tank using the first openings 30.

  • Patent number: 6701727
    Abstract: A management apparatus and a management method which can forecast inspection time before the lowering of performance or the occurrence of abnormality in a heat source unit for an air conditioner are provided. The operating condition of the air conditioner heat source unit is monitored by a central monitoring unit of the management apparatus connected to the heat source unit through an information communication network. Operating data of the heat source unit is analyzed so that the lowering of the performance and the advance of the degree of abnormality in the heat source unit are diagnosed. Thus, the loss of a user caused by the failure stop or the performance lowering of the heat source unit is reduced. Further, the load on the heat source unit is grasped by the central monitoring unit so that remote central control is carried out to make the operating cost minimal.
