  • Patent number: 12215235
    Abstract: Provided is a composite member, including: an inorganic layer that contains an inorganic substance containing at least one of a metal oxide or a metal oxide hydroxide. The composite member includes a resin layer that is provided on a surface of the inorganic layer and contains a resin and inorganic particles that are dispersed in the resin and some of which adhere directly to the inorganic substance of the inorganic layer. A porosity in a cross section of the inorganic layer is 20% or less, and a peak derived from a hydroxyl group is detected for the inorganic layer when measurement is performed using infrared spectroscopy or X-ray diffraction.
    Type: Grant

  • Patent number: 11965921
    Abstract: A measurement system and method tests for spurious emissions included in a signal transmitted from a mobile terminal in a shorter time than before. The system includes: a band division unit for dividing the measurement frequency band into a plurality of divided bands; a first spurious measurement control unit which causes a measurement device to measure the spurious emissions of the signal to be measured in each divided band and the peak power of the spear in each divided band; and a first pass/fail determination unit that determines whether or not pass determination criteria is satisfied. The first pass/fail determination unit determines whether the peak power does not exceed the threshold of the pass determination criteria in each divided band. The threshold value of the pass determination criteria is lower than the threshold of the standard determination criteria defined by the 3GPP standard.

  • Publication number: 20240124622
    Abstract: A film material according to the present disclosure includes an amorphous polymer (A) including a reversible bond which is reversibly dissociated and recombined in response to a temperature change. The polymer (A) has a glass transition temperature of higher than or equal to 40° C. The polymer (A) has a storage elastic modulus of greater than or equal to 0.2 MPa at a temperature higher than the glass transition temperature by 100° C. and a storage elastic modulus of less than or equal to 100 MPa at a temperature higher than the glass transition temperature by 50° C.
