摘要:
A signal discriminator is provided which leverages variation of permittivity of Mn—Zn-based ferrite. The signal discriminator comprises a soft magnetic material which has a capacitive reactance C, and which has its complex relative permittivity varying with frequency such that the real part ε′ of the complex relative permittivity is large in a low frequency domain and small in a high frequency domain. In the reactance component X2, the capacitive reactance C is not negligible with respect to the inductive reactance L in a low frequency domain, in consequence of which the value of the reactance component X2 as a parallel circuit of the capacitive reactance C and the inductive reactance L is caused to decrease, and the influence of the capacitive reactance C is decreased in a high frequency domain. Consequently, the reactance component X2 decreases more than the reactance component X1 of a conventional soft magnetic material, and the X-R cross-point frequency moves to a frequency lower than a conventional X-R cross-point frequency XR1, whereby noises in a frequency band where noise components exist are converted into thermal energy thus reducing the waveform distortion originating from high frequency noises.

In a system for converting an input image signal input from an image input device into an output image signal to be output by an image output device, an image compression unit converts a spectral image input via an image input unit into R, G, and B data, obtains principal component data by making principal component analysis of the spectral image, and stores these data in an input image storage unit. When the principal component data and R, G, and B data are loaded and stored in an output image storage unit, a spectral reflectance reconstruction unit reconstructs the spectral reflectance of each pixel using these data. A printer model determines the dot quantities of inks used to record each pixel in an image output device on the basis of the calculated spectral reflectance, and generates an output image signal for the image output device. In this way, image data which allows to estimate the spectral reflectance characteristics of an input image is provided, and faithful color reproduction can be realized.

An image processing method creates a lookup table having a plurality of grids. The image processing method includes the steps of selecting a grid having a small difference from a target grid from among grids whose output values are calculated; setting an output value of the selected grid as an initial value; optimizing an output value of the target grid by using the set initial value; and storing the optimized output value as an output value of the target grid.

In order that the deflection scanning position can be corrected at a time point within a period for fetching information from a subject to be inspected and improvements in accuracy of chip comparison inspection and an inspection near the wafer outer periphery where distortion is large can be assured by correcting the inspection position and biased distortion at a high speed with high accuracy, a digital deflection control scheme is employed in which the deflection scanning signal and correction are all calculated digitally in a deflection controller for deflecting and controlling a charged particle beam irradiated onto a subject to be inspected and the digital value is sequentially converted into an analog value by a time-series train of digital control signal to form a deflection scanning waveform.

The present invention provides a Mn—Zn ferrite having an electrical resistivity exceeding 1 &OHgr;m order and having a high initial permeability of 4000 or more at 100 kHz and 100 or more at 10 MHz. The main components of the Mn—Zn ferrite include 44.0 to 49.8 mol % Fe2O3, 15.0 to 26.5 mol % ZnO, 0.1 to 3.0 mol % CoO, 0.02 to 1.00 mol % Mn2O3, and the remainder MnO. The Mn—Zn ferrite can be used in a wide frequency region of 100 kHz to 10 MHz by limiting Fe2O3 content to a range of less than 50 mol %, that is the stoichiometric composition, inhibiting formation of Mn2O3 and adding a proper amount of CoO.

摘要:
A test pattern generation apparatus and method for an SDRAM can easily generate a test pattern for the SDRAM by having a specific wrap conversion circuit or an address conversion method. The wrap conversion circuit is provided to receive two kinds of data from a pattern generator and converts the data through a predetermined logic circuit information. The test pattern generation method for the SDRAM is carried out by inputting the column address data Y0-Y2 and the wrap address data Z0-Z2, and by generating output data which has been converted by a predetermined logic equation. The test pattern generation apparatus and method can also include an address inversion scramble for the converted output.
