Title: Device for sensing rf-current to be supplied to plasma and waveform sampling therefor
Inventor: HOPKINS MICHAEL
IPC: G01R31/28
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To eliminate or relieve a problem caused by stray flux. SOLUTION: This device is provided with an RF conductor 30 which supplies current to plasma, and the conductor is divided into two parts 30a, 30b along a part of its length, and formed so that substantially equal current may flowed through the respective parts. By inserting a sensor device 44 in a gap 32 between the two parts, and forming the first and second inductive loops L1, L2 disposed one by one on the respective sides of the gap, magnetic flux generated when RF current flows through the RF conductor is joined to the loops in a reverse direction respectively to the sensor device. If stray flux perpendicular to the direction of the current is joined to the loop in the same direction to the sensor device, such voltage as to be applied to voltage induced in one loop and deducted from voltage induced in the other loop by the RF current is induced in the loop. By serially-connecting the loops, the voltage induced by stray flux is tend to be extinguished.

Title: Annealing method for copper or copper alloy material
Inventor: WATANABE MASARU
IPC: C22F1/08
Filed: 1981-05-07
Abstract: PURPOSE: To prevent sticking by annealing and to obtain a sound annealed material having no sticking flaws by winding a rolled material provided with ruggedness on the surfaces by cold rolling with rolling rolls having roughened surfaces into bobbins and annealing the same.  
     CONSTITUTION: A copper or copper alloy material is cold rolled by using rolling rolls having roll surfaces roughened moderately within an about #80W800 range, whereby the roughness of the roll surfaces is transferred to said material and the rolled material having micro-ruggedness on the surfaces is obtained. Despite the bobbin winding and annealing of such rolled material, the contact areas between the rolling materials are reduced by the ruggedness of the surfaces and  the sticking by annealing is obviated; therefore, the sound annealed material having no sticking flaws is obtained. If the roughness of the roll surfaces is #1000, there is no effect of preventing sticking, and if it is ≤#80, there is possibility of degrading the quality of the annealed material. By the above-mentioned method, the sticking is prevented economically without making production stages intricate.
