IPC: H03G3/20
Filed: 1979-10-31
Abstract: PURPOSE:To obtain a wide-range stereophonic effect regardless of a narrow distance between the speakers, by varying the amplification factors of right and left signals in accordance with the level difference between the right and left signals. CONSTITUTION:The stereo signal supplied from the stereo matrix circuit 1 is applied to the level difference detecting circuit 9 through the tone control circuit 3 after receiving a right-left balance control through the balance control circuit 2. The circuit 9 delivers the stereo signal in the sound volume ratio as it is when no level difference is detected between the right and left signals, and then gives a control to the right-left sound volume ratio varying circuit 10 to give an emphasis to the left signal in case when the left signal is higher than the right signal. The signal thus controlled is delivered through the speakers 7 and 8 via the sound volume control circuit 4 and the amplifying circuit 5. As a result, the stereophonic effect can be enhanced even in case when the distance between the right and left speakers is limited.

Title: Desmutting treatment of steel material
Inventor: UCHIDA MITSUAKI
IPC: C23G1/36
Filed: 1993-05-18
Abstract: PURPOSE:To attain a desmutting treatment free from environmental problem by treating a steel material with a permanganic acid in an aqueous alkali solution and reutilizing the solution after treating it by electrolytic oxidation. CONSTITUTION:The steel material is treated by immersing it in an aqueous solution mixed with the permanganic acid and the aqueous alkali solution. Trivalent Cr forming a smut on the steel surface is oxidized to hexavalent Cr with an oxidative action of the permanganic acid. The smut oxidized to hexavalency can be removed by post-pickling, The aqueous solution after the treatment is electrolytically oxidized to be recycled and reutilized. Since heptavalent Mn of the permanganic acid is reduced to hexavalent Mn by oxidation of the smut, the hexavalent Mn is oxidized to the original heptavalent Mn with nascent oxygen generating at the time of the electrolysis. The alkali chemical is preferably used in the concentration range of 10-20wt.%, and the permanganic acid is preferably used in the concentration range of 3-10%.
