Title: Developing device
Inventor: HOSOYA MASAHIRO
IPC: G03G15/08
Filed: 1982-12-24
Abstract: PURPOSE:To obtain a good developed image by forming the first element for regulating developer thickness near a mobile carrier for carrying the developer on the surface and the second regulating element for rearranging it. CONSTITUTION:A developer 3 is placed in a developer hopper 2 fixed above a grounded conductive mobile carrier 1, and when the carrier 1 moves in the arrow direction, a thin developer layer 3 is formed on the surface of the carrier 1 by regulation of the first regulator 2, and the layer 3 approaches below the second regulator 6. Since this regulator 6 is subjected to AC voltage, when the developer is negatively charged, it jumps toward the regulator 6 at the time of positive phase, and then, gravity and the negative phase draws it down to the surface of the carrier 1, thus vibrating it by the action of the AC electric field. As a result, since the ununiform toner layer is disturbed, a uniform developer layer having a little agglomeration and unevenness or the like is formed after passing below the regulator 6, and an image good in resolution is obtained.

Title: Method for analyzing underground specific resistance structure by double reciprocal boundary element method
Inventor: KAGAWA YUKIO
IPC: G01V3/02
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To develop practical procedures, methods applied to an underground investigation, by measuring a potential to be measures at a potential electrode corresponding to a current supplied to a current electrode at each measuring point on a measuring line, transforming a driving term to a boundary integration and obtaining a specific resistance distribution from the potential to be measured. SOLUTION: An apparent specific resistance is calculated from a feed current and a measured potential obtained after topographic features are corrected. When a measuring line is too long, an analysis measuring line is divided to several sub measuring lines. An average value of the apparent specific resistances is calculated for every sub measuring line. If a ground face is flat or only an underground electrode is measured, a general solution of a potential is obtained analytically from the average value of specific resistances. A difference of the measured potential and the general solution is calculated together with the measured potential and a boundary condition, and a parameter is determined. A distribution of driving terms in an analysis area is calculated.  A specific resistance distribution of each point is calculated for all current sources included in the sub measuring lines according to the method of least squares. The specific resistance distributions of sub areas are connected, thereby obtaining a final analysis result.
