A charging roll includes a cylindrical base member that has a metal-containing surface, a conductive adhesive layer that includes a halogen atom-containing resin and has surface roughness Rz in a range of 0.5 &#x3bc;m to 8 &#x3bc;m on an outer peripheral surface side on the base member, and a conductive elastic layer that is disposed to be brought into contact with the outer peripheral surface of the conductive adhesive layer and includes a halogen atom-containing rubber.

A simulation device calculates an equilibrium arrangement of a set of particles by using a potential function or a force function, which describes an interaction of a particle system, and simulates the particle system by using an obtained equilibrium arrangement as an initial arrangement.

Device and method for generating an arrangement of a set of particles

A processing device generates a model of a tree in a given arbitrary space, reshapes the tree based on the nodes included in the tree, and outputs a reshape result. By repeating the reshape of the tree while examining the cost value of a reshaped tree, a local Steiner tree with a good cost value is obtained. A network shape is optimized by using the obtained local Steiner tree.

Processing device for searching for a suitable network shape in a general metric space

A processing apparatus changes deformation elements composing a shape representing a problem to be processed using a search termination condition, a sequencing algorithm for deformation elements, a cost function and a deformation pattern, and deforms the shape. Then, the processing apparatus searches for a shape with the minimum cost, and outputs the shape as a solution.

Processing apparatus and method for solving optimization problem

In an optimization problem, an optimum solution is searched by using the deterministic dynamics which has a neighborhood search capability, is not trapped into a local minimum state during a search using a search speed control mechanism, and improves the realization probability of the optimum state independent of the search speed.
