Abstract: PURPOSE:To obtain an optimal wrapping material for wrapping a product which needs protection against moisture and electrostatic charge by attaching an electroconductive film provided with moisture permeability at least, on one surface of a base cloth. CONSTITUTION:A wrapping material 2 for protecting against electrostatic charging consists of an electroconductive film 5 capable of air permeability 5 bonded to one surface of a base cloth 4 composed of unwoven cloth, to the other surface of which electroconductive ink 6 such as carbon ink is applied. Especially, the electroconductive film 5 has the function to allow passage of an external air and at the same time, electrically neutralize a static electricity generated by friction of an enclosed product W using an electric conduction phenomenon. The recommended conductive fiber dispersed in the electroconductive film 5 is an organic fiber processed using electroconductive processing. Especially the recommended wrapping material 2 with this conductive film provided on the one surface has a moisture permeability of 2800/m<2>/24 hours or higher and a surface resistance factor of 10<4> to 10<4>OMEGA/square.A sheetlike wrapping material 2 is bent into U shape and then is thermally sealed cylindrically. Further, a desiccant 3 such as silica gel is charged in a bag. If a staticelectricity generates during this charging operation, it is electrically conducted by the conductive film 5 for neutralization.

Inventor: YAMAMURA TAKESHI
IPC: C22B9/193
Filed: 1986-11-19
Abstract: PURPOSE:To prevent degradation of the quality of a refined metal by using a Ca material as an additive charging material no molten slag having degraded refining power at the time of refining the metal by the electroslag refining method. CONSTITUTION:An electrode of the material to be refined is immersed into the initially loaded molten slag of a CaF2-Al2O3-CaO or CaF2-CaO system ad is energized so that the metal of the electrode is melted by the Joule heat of the molten slag. The molten metal is passed in the form of liquid drops through the molten slag and the impurities in the molten metal are removed by the slag, by which the metal is refined. The Ca material such as CaF2 or CaO is used as the additive charging material when the refining power of the molten slag to be used degrades during use. Remaining of Sol, Al as the impurity in the refined metal as in the conventional case of using Al as a deoxidizing agent is obviated and the degradation of the basicity of the molten slag by use of the Ca material is prevented. The degradation of the desulfurization power of the molten slag is thus prevented.

Title: Data processing system
Inventor: MAKI YOICHI
IPC: G06F17/21
Filed: 1986-11-19
Abstract: PURPOSE:To reduce the load of an operator in a stable processing mode by reading the index information out of an index information memory means and carrying out the data processing with use of a 1st character (string) in case a command is produced to perform the data processing for a 2nd character (string) by means of the 1st character (string). CONSTITUTION:An index information part 23B and a 'Japanese rendering' storing part 23C are added to a main memory 23 so that the 'Japanese rendering' data kept erased after selection and decision of KANJI (Chinese characters) is held as necessary as the index information for sorting the 'Japanese rendering' order. Thus, an operator is not required to be conscious of a 1st character (string) before conversion unlike the 'Japanese rendering', in particular, owing to utilization of the index information. Then, the operator pays attention only to the data on a 2nd character (string) like KANJI to be sorted and gives a command to perform the data processing for the 2nd character (string) by means of the 1st character (string). Thus the KANJI can be sorted in the 'Japanese rendering' order serving as the 1st character (string).

Title: Image forming device
Inventor: ISEDA KEN
IPC: B41J2/325
Filed: 1985-12-05
Abstract: PURPOSE:To increase the number of images formed per ink ribbon by arranging a recording head so that it may be positioned above a means to move a member on which an image is to be formed. CONSTITUTION:A cylindrical platen (a means to move a member for an image to be formed) 41 carrying paper P while supporting the latter is driven by a pulse motor 42 at a prearranged pitch through a train of deceleration gears. Above this platen 41, a thermal head (thermosensitive head) 43 is arranged in an opposite position as a recording head. This thermal head 43 moves by a head moving means serving along the axial direction of the platen 41. Therefore, when thermosensitive paper is used as paper P, an image can be formed by arranging the thermal head 43 directly opposed to paper P instead of fitting a ribbon cassette 65. On the other hand, when ordinary paper is used as paper P, the ribbon cassette 65 is set on a ribbon cassette mount 37 formed at the rear edge of a main unit 1, and a thermomelting ink ribbon 67 is interposed beforehead between paper P and the thermal head 4, thus visualizing an image.

IPC: G06F15/78
Filed: 1994-10-13
Abstract: PURPOSE: To efficiently execute a long program even with the program memory of a small capacity and to reduce a burden of a CPU. CONSTITUTION: The DMA instruction of the program is provided together with an arithmetic instruction in the program stored in a program RAM 60. An instruction decoder 65 successively reads the respective instructions of the program out of the program RAM 60, controls respective parts, and when the DMA instruction of the program is decoded in the execution process of the program, activates a DMA controller 22 so as to DMA transfer the program from an outside to the program RAM 60 after saving the value of a program counter 61. Then, after the transfer is ended, the value of the program counter 61 is restored and the execution of the program is restarted. Thus, a DSP 23 is operated so as to replenish its own program by its own program.

Title: Immunological method for determination of human 92kda gelatinase
Inventor: OKADA YASUNORI
IPC: G01N33/573
Filed: 1991-07-26
Abstract: PURPOSE:To determine human 92kDa gelatinase (human MMP-9) in a sample to be inspected, precisely, simply and quickly, by using a monoclonal antibody which is combined specifically with the human MMP-9. CONSTITUTION:Two kinds of monoclonal antibodies which are combined specifically with human MMP-9 are used as antibodies to be combined with a solid- phase carrier or antibodies giving tags thereto, and measurement is executed immunologically by a sandwich method. On the occasion when an antigen- antibody reaction is executed, polyoxyethylene lauryl alcohol ether is added to a reaction liquid preferably in a concentration range of 0.02 to 0.1% (W/V) generally. Thereby nonspecific combination and interference in the antigen- antibody reaction by serum protein can be lessened and, therefore, the human MMP-9 in a specimen can be measured with increased accuracy.

Title: Graphite type electrode rod for arc furnace
Inventor: MORIKAWA KATSUMI
IPC: F27B3/08
Filed: 1993-11-02
Abstract: PURPOSE:To form a covering layer for prevention of electrode rod exhaustion due to oxidation, wherein the operating environmental problem due to the execution of works in the operating condition is solved, which is required to form non-conductive covering layer with avoidance of the electrode holder part, and also oxidative exhaustion of the applicable part is eliminated likely caused by execution of works in band form when a separate work takes place. CONSTITUTION:Instead of a conventional non-conductive oxidation preventive layer, a material is used which is prepared by adding an appropriate amount of conductive filler consisting of metal powder, graphite powder, etc., to an admixture chiefly containing a powder-form glass frit and an inorganic binder, and thereby an oxidation resisting covering having an electric conductivity of no more than 10<2>OMEGA.cm is yielded. This eliminates oxidation of the outside surface of a graphite type electrode rod to permit the electrode to undergo only tip exhaustion generated by arcs, and as a result the exhaustion of carbon electrode is reduced to a great extent.
