Title: Image emphasizing device
Inventor: MATSUMOTO NORIYUKI
IPC: G06T5/00
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To obtain a sharp image by weighting a Fourier coefficient decided by subject the original image data to Fourier transform in a prescribed direction in order to emphasize an unclear part, acquiring the minute amplitude value emphasis data for the weighted Fourier coefficient and acquiring the image data from the minute amplitude value emphasis data. SOLUTION: A two-dimensional fingerprint original image 200 is sent to a minute amplitude value emphasizing means 2 as the two-dimensional gradation signals, and the Fourier transform means 211 and 212 of the means 2 perform the Fourier transform of the gradation signals in X and y directions to decide a Fourier coefficient respectively. These Fourier coefficients are weighted by the weighting means 221 and 222, and the inverse Fourier transform means 231 and 232 inversely Fourier transforms those weighted Fourier coefficients in each direction. Thus, the minute amplitude value emphasis data 241 and 242 are obtained and then synthesized into a minute amplitude value emphasis image 260 by a synthesizing means 250.

Abstract: PROBLEM TO BE SOLVED: To surely eliminate the residue of a resist film, by preparing a wafer wherein BLM is formed on an electrode pad, performing oxygen plasma ashing treatment as the film formation pretreatment of a solder layer formation, and then performing sputter etching treatment using inert gas. SOLUTION: A substrate to be treated (wafer) is set in a parallel flat plane type RF plasma treatment equipment. oxygen O2 is introduced in a plasma treatment chamber, and the pretreatment of forming a solder evaporation film is performed. In the substrate to be treated after plasma ashing treatment, residue 6a in an aperture part 5 bottom is eliminated. But the surface of barrier metal in a resist aperture part 5 is a little oxidized. In order to eliminate the oxide film, argon gas Ar is introduced in the plasma treatment chamber, and film formation pretreatment is performed. As the result, an oxide film on the surface of barrier metal in the resist aperture part 5 is sputtered, and the state of a clean metal surface is obtained. Therefore, excellent electric contact on the interface of a solder ball bump after finishing and substratum metal can be obtained.

Abstract: PURPOSE:To prevent the redissolution of evaporated impurities into the condensate by providing a condensation part in a evaporation part to keep the temp. of the condensate in the condensation part stably at a temp. close to the b.p. in the titled distilling purifying device for producing extremely pure water.

Particulate impurities are removed from the evaporated steam by a filter 6, and then the steam is introduced into a condenser 7. The steam introduced into the condenser 7 is cooled by a cooling pipe 8, condensed, and accumulated at the lower part as a condensate. At this time, since the condenser 7 is heated by the outside evaporator, the temp. of the condensate is kept at a temp. close to the b.p. Consequently, soluble impurities which have been contained in the raw water and evaporated in the evaporator are not redissolved in the condensate even when introduced into the condenser, and high-purity distilled water is produced.
