Abstract: Disclosed are a synthetic resin composition for use as building materials such as window frames, as well as a product manufactured using the same. More particularly, the synthetic resin composition comprises a tetrapolymer of acrylic rubber-styrene monomer-butadiene rubber-vinyl cyanide monomer and a styrene-vinyl cyanide copolymer having a high molecular weight and a high degree of dispersion. Unlike products manufactured using prior polyvinyl chloride (PVC), building material such as window frames manufactured using the synthetic resin composition are recyclable, and thus can contribute to a reduction in the generation of hormone-disrupting chemical dioxin, which is released in the burning thereof. Also, the resin composition can be manufactured into products having excellent properties of weather resistance and colorability without using environmental pollutants such as cadmium stearate or lead stearate, which are used as thermal stabilizers.

Abstract: The present invention relates to an impact absorbing dumbbell and an impact absorbing barbell disk. The impact absorbing dumbbell includes an outer cover prepared by cutting a flexible member into a dumbbell and sewing the cut flexible member, thereby having a dumbbell shape, a cylindrical tubular body installed inside the middle portion of the outer cover for serving as a handle and keeping the dumbbell shape, and weight constituent powder charged in the outer cover. The impact absorbing barbell disk includes an outer cover prepared by cutting a flexible member into a barbell disk and sewing the cut flexible member, thereby having a barbell disk shape, weight constituent powder charged in the outer cover, and a bushing made of metal or synthetic resin, the bushing being inserted and fixed in the central shaft hole of the outer cover.

Abstract: The disclosure is a data processing device with selective data cache architecture and a computer system including the data processing device. The data processing device is comprised of a microprocessor, a coprocessor, a microprocessor data cache, an X-data cache, and a Y-data cache. The microprocessor fetches and executes instructions, and the coprocessor carries out digital signal processing functions. The microprocessor data cache stores data provided from the microprocessor. The X-data cache stores a first group of data provided from the coprocessor while the Y-data cache stores a second group of data provided from the coprocessor.
