IPC: G01R21/133
Filed: 1987-09-24
Abstract: PURPOSE:To accurately measure reactive power without being affected by variation in frequency by generating a signal of frequency proportional to the reactive power according to a reference voltage corresponding to the frequency of a load voltage and an electric power multiplication output. CONSTITUTION:A voltage detection part 1 and a current detection part 2 output signals ev and ei proportional to the load voltage V and current consumption I and the voltage signal ev is delayed in phase by pi/2 through a delay part 3 and supplied to a power multiplication part 4. The power multiplication part 4 multiplies the delayed voltage signal eva by the voltage signal ei and outputs a power multiplication voltage signal eq. A reference voltage generation part 5, on the other hand, detects the frequency of the voltage signal ev and generates the reference voltage signal er corresponding to the frequency. Then a voltage- frequency conversion part 6 converts the power multiplication voltage signal eq from the power multiplication part 4 into a frequency signal fq proportional to the reactive power while correcting the signal eq according to the reference voltage signal er from the reference voltage generation part 5 and outputs the signal fq as a signal which is not affected by the frequency variation.

Namely, the oil content absorbed by the porous base material 1 is further absorbed by the oil absorbent, so that the sheet has excellent oil holding property. Moreover, since the hydrophilic porous base material 1 is used, the oil content once absorbed by the porous base material 1 is efficiently transferred to the oil absorbent 2, and thereby, the oil-absorbing sheet has a dry surface with little tacky state due to the oil content.

Filed: 1988-09-22
Abstract: PURPOSE:To correct the discontinuation of phases and to prevent an error to be caused by phase jump by separating an image area into the suitable number of voxcels, detecting an area to have possibility to generate the phase discontinuation, executing phase shift to the whole areas and executing reverse phase shift to this detected area. CONSTITUTION:In a chemical shift image preparing method to obtain a chemical shift image, for which the phase error of a Dixon method to separate and display the images of water and fat is corrected, the image area is divided into 32X32 voxcels. When the image area is defined as (256)<2> pixels, the condition of 1 voxcel=64 pixels is obtained. This division is executed with a purpose to suppress the influence of noise, to decrease resolution so that the correction can not be missed by the slight change of the phase and to execute average operation. The voxcel to include the phase of the pixel Pij>alpha or Pij<-alpha by >=6 pixcels is extracted as a phase jump voxcel. In such a condition, alpha=160 deg.. The phase jump voxcels are linked and a phase jump area is limited. For this limitation, phase jump voxcels 22 in an image 21 are linked and a closed area 23 is provided in an outside rather than a linking line and defined as the phase jump area.
