Abstract: In a grinding machine comprising conductive grinding wheels, the invention presents a truing technique capable of truing grindstone surfaces of grinding wheels at high precision in a short time. For example, in the case of truing flat annular grindstone surfaces (10a, 10a) of a pair of mutually opposite grinding wheels (1, 2) simultaneously, an electro-discharge truing electrode (20) is disposed oppositely between the grindstone surfaces (10a, 10a) of the two grinding wheels (1, 2), and while traversing relatively parallel along the both grindstone surfaces (10a, 10a), the grindstone surfaces (10a, 10a) are trued without making contact by the electro-discharge action between the electro-discharge truing electrode (20) and both grindstone surfaces (10a, 10a).

Abstract: In a method of calculating effective power relating to a capacitor, the waveform of a periodic voltage applied to a capacitor is set. The capacitance of a desired capacitor is input. The waveform of the periodic voltage applied to both ends of the capacitor is subjected to Fourier expansion. More specifically, the periodic voltage is Fourier-expanded in terms of sine and cosine-wave series of high-order frequency components. Further, an effective power consumed by the capacitor is calculated using data regarding temperature characteristics, voltage characteristics and a frequency characteristic of the capacitance and dielectric tangent of the capacitor.

Abstract: Conventional nanocomposites using swelling layered silicates, which are low specific gravity and have markedly improved heat resistance, rigidity and gas barrier compared with talc or mica filling composites, are available. They are, however, much inferior to glass fiber filling composites (FRP) for rigidity and heat resistance if not regarding difference of specific gravity and they may not respond to current high level requirements. The inventors have found that an organic-inorganic composite can be formed by substituting K ions between layers of high-crystalline non-swelling layered silicates composed of mica and having primary particles of large particle size with any positive charged organic compound under specific conditions, leading to completion of the invention which enables production of polymer composite materials having the layered silicates delaminated and dispersed.

Abstract: A method and apparatus are used for truing grindstones. Grinding wheels are arranged in a manner such that the respective grindstone surfaces are disposed apart from each other to define a space therebeween and respective ones of the grindstone surfaces are positioned in respective planes with the planes extending parallel to each other. Each grinding wheel is composed of a conductive grindstone having abrasive grains bound by a conductive binding material. An electrode discharge is applied from an electro-discharge truing electrode disposed in the space between the grindstone surfaces in a non-contacting relationship with the grindstone surfaces. The electrode discharge occurs in respective gaps formed between the electro-discharge truing electrode and the grindstone surfaces. The electro-discharge electrode is moved relative to the grindstone surfaces while applying the electrode discharge so that the grindstone surfaces are trued thereby.
