IPC: H04B3/14
Filed: 1994-06-14
Abstract: PURPOSE:To provide an automatic equalizer in which waveform equalization is conducted depending on the length of a transmission line independently of the presence of a bridge tap(BT). CONSTITUTION:An equalizer training signal received via an input terminal 21 is given to a sq. rt. f equalizer 23 and the attenuated waveform part of a prescribed shape in existence periodically is stored in an input waveform memory 28 via an A/D converter 27. A detector 26 detects the maximum level of a substantial equalizer training signal, the maximum level of a BT echo and the delay time of the BT echo of the substantial equalizer training signal from the maximum level as parameters based on waveform data stored in the input waveform memory 28. An attenuation ROM table 25 selects a line attenuation when a transmission signal passes through a transmission line without a BT based on the detected parameters and an amplification factor of an AGC amplifier 22 and selectors and decides a sq. rt. f equalization coefficient correspondent to the line attenuation from the equalization coefficient ROM table 24.

Title: Rf etching device
Inventor: YAGI HARUYOSHI
IPC: H01L21/3065
Filed: 1989-05-24
Abstract: PURPOSE:To produce a clear etching surface and improve an electrical contact by circulating liquid nitrogen internally and cooling an anode to liquid nitrogen temperature. CONSTITUTION:Liquid nitrogen is introduced from an inlet 21 and discharged from an outlet 22, and is circulated internally of an anode 5. For a cathode counter wall surface of the anode 5 the whole anode 5 is of course cooled to liquid nitrogen temperature. Accordingly, degassing such as water can be adsorbed by the wide surface area anode 5 to prevent such water from being deposited onto a wafer 4. Further, adsorbed gas such as much water adsorbed on the wall surface of the anode 5 is removed when an etching device 1 is returned to room temperature upon periodical cleaning. Hereby, a clean etching surface is formed to improve electrical contact.

Filed: 1988-06-01
Abstract: PURPOSE:To realize the linear density conversion of high-quality pictures regardless of a white or black ground picture by applying the density of a picture to be processed to the conversion of an inverted picture and at the same time giving the second density inversion to the converted picture to output the inverted picture after returning it to the original picture property. CONSTITUTION:The black/white inverting circuits 5 and 6 serving as the density conversion means which invert the picture density are set at the picture input and output parts of a picture processor consisting of a line buffer 1, a converted picture element position detecting circuit 2, a picture element extracting circuit 3 and a conversion arithmetic circuit 4. Then the density of an input picture is inverted according to the property (white or black ground picture) of the input picture. This inverted density is applied to the linear density conversion carried out by the picture processor and at the same time the density of an output picture undergone the linear density conversion is inverted and outputted. Thus a high-quality linear density converted picture is simply obtained with no change caused to a conversion parameter even in case only a conversion parameter is set at the circuit 4 with preference given to the black picture elements.

This Al (alloy) is then subjected to AC electrolysis in an electrolytic bath for secondary treatment to dissolve metal salt such as sulfates and hydrochlorides of Ni, Su, co. In this method, aging of the electrolytic bath for primary treatment may be retarded, so that the bath can be used for a longer period of time. Besides, the obtained colored film has a uniform luster and is not discolored even if exposed to ultraviolet rays for 200hr. Hence, the colored film may be used in decorative items, electric household appliances, and interior and exterior furnishing meterials of building.
