Abstract: An information processing apparatus is equipped with an input unit which inputs a first self-transfer function which is acquired by measuring a response at an evaluation point to an input from the evaluation point and each first transfer function which is acquired by measuring a response between the respective connection points to the input, a first estimation unit which estimates each second self-transfer function by using the first self-transfer function and each first transfer function, a first calculation unit which calculates an element vector of each connection point on the basis of each second self-transfer function which has been estimated by the first estimation unit, a second estimation unit which estimates each second transfer function between the connection points on a vector space by using the element vector of each connection point, and a construction unit which constructs a third transfer function by using each second self-transfer function and each second transfer function.

Abstract: The present invention provides a method for surface treatment of inorganic particles, which does not require a large amount of a solvent and may not impair quality of the surface treatment, and also achieves high productivity. Also the present invention provides surface-treated inorganic particles which can be dispersed uniformly and finely, as a reinforcer or modifier for polyester and polyamide resins, and exert an isotropic effect of reinforcing resins, a warp suppressing effect and an excellent crystallization accelerating effect. The inorganic particles are surface-treated by kneading a system containing inorganic particles and a treating agent using a kneader.

Abstract: The present invention relates to a structure of a vibration operated generator which makes it possible to generate electricity by using vibration or swinging to cause electromagnetic induction. The present invention comprises a combination of a guide with a concave surface including a non-magnetic material, a permanent magnet being placed on the concave surface of the guide such that the magnet freely rolls over this concave surface, and electromagnetic induction coils being disposed in positions that cut across the magnetic flux generated by the permanent magnet.
