Abstract: A bagmaking and packaging device includes a transverse sealing unit, a first tube member, and a gas flow path member. The first tube member is disposed above the transverse sealing unit and extends in an up and down direction. The first tube member allows a packaging material to become wrapped around it to thereby form the packaging material into a tubular shape. At least part of the gas flow path member is disposed inside the first tube member. The gas flow path member delivers nitrogen into the packaging material formed into the tubular shape. The first tube member includes a cutout portion that extends in the up and down direction. The cutout portion is formed so that the nitrogen can move between a space between the packaging material formed into the tubular shape and the first tube member and the inside space of the first tube member.

Abstract: A nonlinear distortion is compensated based upon a characteristic relating to a characteristic of a device under test. An inverse characteristic measuring device measures an output signal output from the device under test as a result of supplying the device under test with an input signal generated by a signal source. Further, the inverse characteristic measuring device acquires an ideal signal output from the device under test based upon the input signal if the device under test is ideal. Moreover, the inverse characteristic measuring device acquires an inverse characteristic which is a relation of the ideal signal with respect to the output signal. This inverse characteristic is applied to a distortion compensator. The distortion compensator supplies the device under test with the input signal converted based upon the inverse characteristic. As a result, a signal output from the device under test is an ideal signal whose distortion caused by the device under test is compensated.

Abstract: There are provided frequency analyzing method and apparatus, and a spectrum analyzer capable of reliably detecting and displaying a radio wave even if the radio wave is a frequency spread or low level one. A signal to be measured existing in a frequency band to be measured is extracted by a plurality of measurement signal extracting devices, and each of the extracted plural signals to be measured is frequency analyzed to compute a correlation value with respect to the plural results of frequency analyses. If the computed correlation value is equal to or greater than a preset value, a decision that the signal to be measured exists in the analyzed frequency is rendered, and if the computed correlation value is smaller than the preset value, a decision that the signal to be measured does not exist in the analyzed frequency is rendered. The decision results are displayed.
