Title: Method for determining constitution of power system radial pattern
Inventor: TSUJI KOICHI
IPC: G05B13/02
Filed: 1998-02-14
Abstract: PROBLEM TO BE SOLVED: To formulate a problem of determining the constitution of a system in a radial pattern using restrictive conditions and object functions and find solutions by linear programming, by taking branch tidal current and slack tidal current as variables and expressing the power system using Kirchhoffs first law only. SOLUTION: Branch tidal current and the supply tidal current (slack tidal current) of a feeder are expressed as variables PB and PS, respectively, and loads L1-L4 are connected with nodes 2, 4, 5, 6. Kirchhoff's first law is applied to the nodes, and the relation between the variables is formulated. Consequently, object functions are given to the restrictive condition equations of a system in a radial pattern, and the most effective system constitution is determined. As a result, object functions can be expressed using only non-based variables. Consequently, for example, the most effective system constitution to minimize transmission loss can be determined by linear programming using combinations of variables which allows minimization of the object functions.

Title: Filter material
Inventor: KOBORI AKIRA
IPC: B01D39/18
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To obtain a filter material which is scarcely pitted even if instantaneously brought into contact with flames or receiving intense heat and which is not burned itself while fire is extinguished even if an oil adheres thereto and is fired by binding a fiber web mainly consisting of cellulose fibers with a flame-resistant thermally plastic resin to which a metal hydroxide is added. SOLUTION: This filter material 1 is produced from a fiber web mainly consisting of cellulose fibers 2 bonded with a flame-resistant thermoplastic resin 3 to which a metal hydroxide is added. Since a flame-resistant thermoplastic resin 3 to which the metal hydroxide is added is used, the filter material has excellent flame-resistant property and is hardly burned even if an oil adheres to it and, even if the resin itself is carbonized due to intense heat, the bond is maintained. The flame-resistant thermoplastic resin 3 containing the metal hydroxide is produced by, for example, mixing the metal with a solution, e.g. an emulsion, comprising the flame-resistant thermoplastic resin and the resultant resin is supplied to the fiber web through a spraying, coating, or immersing process and stuck to the fiber web through a drying process.
