Title: Tape initializing method
Inventor: KIYONAGA NORIYOSHI
IPC: G11B15/02
Filed: 1990-09-14
Abstract: PURPOSE:To shorten time required for a tape initializing processing by setting an area designation section and a recording scheduled area at tape feed speed faster than normal recording speed. CONSTITUTION:When an initializing command is given from a computer 11 to a control circuit 3, a magnetic tape is traveled at speed twice as much as regular recording by the circuit 3. At the same time, an operation recording information showing the recording scheduled area of the tape 7 is started. The tape speed of the recording operation is set to be slightly faster than that at the time of recording. When prescirbed time sufficient for recording position information elapses, tape speed is switched to that ten times as much as speed at the time of recording and the circuit 3 retrieves the terminal position of the recording scheduled area. At termination position retreival operation, the recording operation is not executed but it is executed by clocking the elapse of prescribed time. Thus, time required for the tape initializing processing can be shortened.

Abstract: PURPOSE:To detect border temperature according to a potential difference appearing between voltage detection electrodes by allowing currents to flow to both two semiconductor layers of a detecting element after a current flows to only one semiconductor layer until an intrinsic area is entered and then the intrinsic area is entered. CONSTITUTION:Lines of magnetic force of a magnetic field which is applied cross both the line connecting a couple of current feed electrodes 13a and 13b and the line connecting a couple of voltage detection electrodes 15a and 15b.

Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a dielectric film as well as its forming method which comprises a CeO2 film of high crystallinity without formation of an SiO2 layer double domain. SOLUTION: An Mg layer 22 of and a Ce layer 23 of a single crystal are formed continuously on an Si substrate 21, and then O2 molecule 24 is supplied on the Ce layer 23. The Ce of Ce layer 23 is oxidized to form a CeO2 layer 25, while a part or the entire of Mg layer 22 is oxidized to form an MgO layer 26. Also Mg, Bi and Zr, etc., may also be used. Since a metallic material film is formed on a semiconductor layer such as Si substrate, a material for constituting a semiconductor layer, such as a silicon oxide film, is tends to be difficult to formed, so a dielectric film with a large capacitance per unit area, which comprises a base material layer such as MgO layer with high dielectric constant as well as crystalline CeO2 layer, is provided. With the sufficient thickness of a dielectric film, leakages are reduced and breakdown strength is improved.

Title: Method for electrolytically refining copper
Inventor: ANDO KOJI
IPC: C25C1/12
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To suppress the elution of impurities into an electrolyte, to control the lead in an electrolyte purifying stage to remove the contained impurities and to obtain a high-purity electrolytic copper at a low cost. SOLUTION: The lead grad in an anode is adjusted to 0.1-0.2wt.%. Namely, the lead grade is adjusted so that the Sb/Pb weight ratio is controlled to <=0.4, the Bi/Pb in weight to <=0.2 and the As/Pb weight ratio to >=0.4. Consequently, the elution of Sb in the anode into an electrolyte is controlled below 55% and the elution of the Bi in the anode into the electrolyte below 35%, and both elutions are decreased below the conventional actual results. Further, since the As/Pb in weight is controlled to >=0.4, passivation is prevented even in the operation at >=300A/m<2> cathode current density.
