Title: Method for chemical shaving finish and pickling of copper rod
Inventor: BENJIYAMIN EI ESUKOOBAA JIYUNI
IPC: C23G1/10
Filed: 1988-02-01
Abstract: A process for producing copper rod having an improved surface smoothness and substantially no surface oxides, which rod is suitable for drawing or rolling into wire, is disclosed. The process comprises the steps of forming a bath of molten pure copper, casting the molten copper into a cast bar, conditioning the bar for hot-rolling, hot-rolling the bar to form a hot-rolled rod, cooling the hot-rolled rod and chemically shaving and pickling the hot-rolled rod. The chemical shaving and pickling step is performed with a solution containing controlled concentrations of sulfuric acid and hydrogen peroxide. Both the solution and the rod are maintained at elevated temperatures and the duration of the reaction is controlled. The interrelated process variables are regulated so that substantially all of the surface oxides and a desired amount of copper are removed from the surface of the hot-rolled rod.

IPC: G06F17/21
Filed: 1989-01-31
Abstract: PURPOSE:To improve the data input speed by displaying the image of an original read by an image reader and stored at a part of a screen of a display part and at the same time scrolling the display of the image with operation of a keyboard. CONSTITUTION:An operator performs a preparatory operation to read an image out of an original via an image reader 12. A control part 13 stores temporarily the read image and displays it at a display part 15. For a main operation of a word processor, the operator inputs data via a keyboard 14 by reference to the image shown at the part 15. Then the operator scrolls the image on a screen with operation of the keyboard 14 and displays the unprocessed image stored in a storage part 13b when the input is through with the image displayed at the part 15. These operations are repeated so that the data can be inputted to the word processor at a high speed and with no fatigue of the operator.

Title: Level control circuit
Inventor: OKASHIN YAMATO
IPC: H03G3/30
Filed: 1979-02-22
Abstract: PURPOSE:To facilitate the IC formation by omitting the DC cutting capacitor, at the same time preventing occurrence of the distortion. CONSTITUTION:Shunt AGC is given through TrQ11-Q18 to the reception signal which is supplied to transistors TrQ1 and Q2 from tuning circuit 1. In other words, the equal collector current flows to TrsQ11 and Q12 via the AGC current sent from AGC signal formation circuit 7. But the collector current of the same scale as that of TrQ11 flows to TrQ14 since TrsQ13 and Q14 form the current Miller circuit. Then current I1 proportional to the AGC current flows to the line of TrQ12 TrQ15  TrQ17 TrQ14. As TrsQ15 and Q16 plus TrsQ17 and Q18 form the current Miller circuits each. collector current I2 of TrsQ16 and Q18 become identical to I1. Thus current I2 varies in accordance with the change of the AGC current, and accordingly the impedance of TrsQ16 and Q18 have variation.
