Title: Image forming device
Inventor: WATANABE JUNJI
IPC: G03G15/00
Filed: 1988-12-13
Abstract: PURPOSE:To automatically feed and eject a document of a size larger than a document size corresponding to a document carrying-in/out means by separating the platen sheet of a platen unit, which is next to the document carrying-in/out means for automatically carrying a document in and out, from a document platen as required, thereby creating a receiving space. CONSTITUTION:The platen unit 34 is independently placed next to the document carrying-in/out means so that it can be freely opened and closed; when the platen sheet 62 covers the original platen 31, a space 9 can be created by separating the sheet 62 from the original platen 31, thereby receiving a document D from the document carrying-in/out means 33. Even if the size of the document carrying-in/out means 33 corresponds with a small-sized document D, a document D of the largest size, on which a main body device can copy, can be handled by sending a document D toward the platen sheet 62.

Title: Nickel positive electrode active material
Inventor: MORISHITA SHINYA
IPC: H01M4/52
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To provide high output, to prevent the degradation of a charge accepting property due to an electrolytic side-reaction of water in charging and to reduce a material cost by setting the product of the particle diameter and the specific surface area of nickel hydroxide fine particles equal to or less than a certain value. SOLUTION: The product of the particle diameter and the specific surface area of nickel hydroxide fine particles is set <=50 μm.m2/g in order to reduce positive electrode resistance. In this case, the smaller the product of the particle diameter and the specific surface are of nickel hydroxide fine particles, the better, and a value <=30 μm.m2/g is desirable, and the particle diameter <=5 μm or and the specific surface area <=6 m2/g are most desirable. This increases the bulk surface area of an active material and decreases the hydrogen concentration gradient of the bulk surface. A high output can be provided by the acquisition of a hydrogen movement quantity on the bulk surface and the reduction of the positive electrode resistance, and the electrolytic reaction of water generating oxygen does not occur, so that a charge accepting property is improved.  Since the specific surface area of nickel hydroxide fine particles is restrained, the addition quantity of expensive cobalt oxide for imparting conductivity can be reduced.

Title: Manufacture of positive electrode for nonaqueous electrolyte battery
Inventor: MURATA TOMOYA
IPC: H01M4/08
Filed: 1992-11-24
Abstract: PURPOSE:To increase a specific surface area of MnO2, and improve low temperature time discharge characteristics by using MnO2 whose specific surface area is special before heat treatment, and carrying out the heat treatment at a specific temperature after a positive electrode mix is formed by mixing an electrically conductive agent and a binding agent in this. CONSTITUTION:A lithium battery is formed of a positive electrode 1, a negative electrode 2 and a porous separator 3. The positive electrode 1 is formed by using MnO2 as a positive electrode active material, and an electrically conductive agent composed of graphite and acetylene black and a binding agent composed of polyvinyl butyral and alcohol are added and kneaded together, and a positive electrode mix is formed. After extrusion molding is carried out in a sheet shape by using MnO2 whose specific surface area is not less than 50m<2>/g before heat treatment, the heat treatment is carried out at 270 deg.C-330 deg.C, and moisture and the binding agent are removed, and a positive electrode is formed. In this way, since heating treatment is carried out at a low temperature by using MnO2 whose specific surface area is large before the heat treatment, the specific surface area after the heat treatment can be increased. Since this MnO2 is used as the positive electrode mix, the degree of activity of MnO2 can be heightened, so that low temperature time discharge characteristics can be improved.
