Abstract: The present invention is to provide a kneading-type antistatic agent which can be obtained through polymerization simply and conveniently by irradiating active energy rays, and a kneading-type antistatic agent which can be kneaded into a thermoplastic resin, thereby imparting excellent permanent antistatic properties to a molded article without affecting the appearance of the molded article. Therefore, the antistatic agent is a kneading-type antistatic agent which is a thermoplastic polymer obtained by irradiating active energy rays toward a solution which contains A Ingredient: a polymerizable monomer containing in one molecule one polyalkylene glycol and one polymerizable functional group selected from an acryloyl group and a methacryloyl group, B Ingredient: perchlorate and C Ingredient: photo polymerization initiator.

Abstract: An object of the present invention is to provide a polypropylene resin composition that is blended in a polyolefin resin to improve its surface characteristics and impart sustained water repellency and yet is low in aggregates so as not to deteriorate the visual appearance, a polyolefin resin composition containing the polypropylene resin composition, and a molded article of the polyolefin resin composition. A composition that achieves the object is a polypropylene resin composition obtained by heating and kneading a material containing (A) a polypropylene resin, (B) a polypropylene wax, (C) a polyorganosiloxane containing at least one silicon-atom-bonded alkenyl group in each molecule, and (D) an organic peroxide.

Abstract: A phase synchronizer is disclosed that provides a stable output signal while improving synchronization speed. The phase synchronizer includes one or two feedback circuits. The feedback circuit(s) includes a phase comparator for generating a pulse signal in accordance with a difference between the phases of an input signal and a feedback signal, a charge pump for converting the pulse signal supplied from the phase comparator to an analog voltage signal, a loop filter for removing high-frequency signal components from the analog voltage signal output from the charge pump and supplying as a filtered analog voltage signal (LF1 or LF2), and a voltage-controlled oscillator coupled to the loop filter for generating an oscillation output signal having a frequency which varies in accordance with the filtered analog signal (LF1 or LF2). The oscillation output signal is also supplied as the feedback signal to the phase comparator.
