Title: Highly rigid damping material and manufacture thereof
Inventor: OKUZAWA MASAYUKI
IPC: B29C67/02
Filed: 1990-11-30
Abstract: PURPOSE:To improve cutting-forming workability besides lighter in weight by coating granular material with copolymer resin such as acrylic ester and vinyl chloride, styrene or vinylidene chloride or the like, unitizing a coating layer surfaces by means of heat fusion, and making it have high dampability with high rigidity. CONSTITUTION:Granular material 1 consisting of flaky fine particles is coated with copolymer resin 2 of acrylic ester and vinyl chloride, styrene or vinylidene chloride, and the coating layer surfaces are unitized by means of heat fusion. Since the granular material 1 of the flaky fine particles is coated with the copolymer resin 2, a compounding ratio of the granular material 1 becomes enhanced, and thereby a Young's modulus is enlargeable and, what is more, a surface area of the flaky fine particles is large enough, so that a loss attributable to sliding friction with the copolymer resin 2 comes large, thus high dampability is maintainable. Moreover, it is suitable for such a highly rigid damping material that is ease of cutting-forming working besides lighter in weight.

Title: Switching control system for stabilized power supply
Inventor: ARIMURA KENICHI
IPC: H02M3/335
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To obtain a switching control system in which the switching operation of a stabilized power supply receiving the rectified voltage of an AC power supply as a DC input voltage is controlled in such a way that the waveform of a current taken from the AC power supply becomes a sine-wave shape while a converter or the like is not built in the input side. SOLUTION: A correction signal Sa whose phase is identical to that of the voltage Va of an AC power supply formed by a resistance voltage-dividing circuit 40 receiving a rectified voltage from a rectifying circuit 10 and which has a nearly sine-wave shape is superposed on an error signal Se expressing the difference between an output voltage by an error signal circuit 30 and a target value, and a control signal Sc is formed. The control signal Sc and a reference signal Sr which is synchronized with the switching cycle of a stabilized power supply and which has a pulsating waveform are compared by a comparator 22 at a control circuit 20. The on-off state of a switching transistor 2 is controlled at a timing at which the instantaneous value of the control signal Sc cuts the waveform of the reference signal Sr.  Thereby, the waveform of a current Ia which is taken from the AC power supply is corrected to a nearly sine, waveform whose phase is identical to that of the AC voltage 1a, the harmonic portion of the current Ia is reduced, and the power factor of electric power taken from the power supply is enhanced.
