    摘要: An improved power system control apparatus which reduces power fluctuations and includes an estimated unit for estimating the system impedance and phase difference angle using the generator power transmission terminal voltage, the reactive power and effective power of the system. The invention enables accurate power system impedance estimates in a real-time manner. The invention can be applied to a filter device for removing noise components from an angular velocity signal. The filter device comprises first arithmetic means for calculating changes in phase angle, second arithmetic means for calculating changes in angular velocity, a first integrating for integrating the changes in the phase angle to obtain an estimated phase angle, a second integrator for integrated the changes in angular velocity to obtain an estimated angular velocity and a power stabilizing filter for filtering the estimated angular velocity signal.

    摘要: A coated stainless steel article and a method of preparing the article are disclosed. The coating is a plasma chemical vapor deposited coating, formed from a plasma of nitrous oxide, a silane, and an energy transfer agent (such as He, Ar). The resulting coating is adherent, corrosion resistant, and has a thickness sufficient to mask and cover the features of the stainless steel substrate, and to provide a pitting potential (in 3.5% NaCl) of greater than 600 millivolts, a J.I.S. 8502 (1982) versus a saturated calomel electrode a salt spray test rating in 5% NaCl-0.02% hydrogen peroxide of at least B.

    摘要: A system for detecting the intensity of knocking of an internal combustion engine such as an automotive gasoline engine, comprising a vibration sensing device attached to an engine body and electrical circuitry for producing a knock-indicating signal based on a comparison of a vibration-indicating signal derived from the vibration sensing device with a reference signal which is variable depending on the rate of engine revolution. The vibration sensing device comprises a vibration pickup such as of an accelerometer type, preferably mounted on a resonance plate which is fixed only at its one end to the engine body, and is made to have a resonance frequency within a frequency band of vibrations attributable to knocking of the engine, such as 5 to 10 KHz, so that no band-pass filter is needed in this system.
