摘要:
The present invention relates to a method for producing hEGF (human epidermal growth factor) which has the same activity as the wild form, in high concentration and with a high degree of purity. More specifically, the invention relates to an hEGF expression vector comprising a nucleic acid sequence coding for the polypeptide of sequence number 14; a host cell in which the expression vector has been genetically transformed; and a method for producing hEGF, comprising a step in which the expression vector is created and is genetically transformed in yeast from which the KEX1 gene is lacking. Using the method of the present invention, it is possible to produce a large volume of human derived EGF which has the same size and activity as human derived EGF, and this EGF can be used in various ways such as in medicine and cosmetics.

A golf ball including a composition having an unsaturated polymer, a cross-linking agent, a peptizer, and an accelerator. The composition can be incorporated into the golf ball's core, intermediate layers, and cover layers, and can provide optimal performance and durability properties. The golf balls incorporating the composition are easy to manufacture.
摘要:
The present invention is directed to a two-piece golf ball having a core and a cover, wherein the core comprises at least one unsaturated polymer, at least one cross-linking agent, at least one co-cross-linking agent, and at least one peptizer (comprising one or more organic sulfur compounds, or one or more metal or non-metal salts of an organic sulfur compound), and optionally at least one weight adjusting filler. The improved two-piece balls have optimal velocity and distance performance, as well as excellent shot feel, the called “long and soft” combination. The balls also demonstrate excellent durability properties, and ease of manufacture.

A variable square-wave drive device for controlling square waves using feedback- and bias-control methods. The variable square-wave drive device includes an oscillator for generating a clock pulse; a frequency-divider/duty controller for frequency-dividing the clock pulse received from the oscillator to generate a clock signal and a square-wave signal; a drive for amplifying the square-wave signal received from the frequency-divider/duty controller according to a bias voltage, generating first and second square-wave signals having opposite phases, and outputting the first and second square-wave signals as a square-wave drive signal; a feedback controller for comparing a predetermined voltage variable determined by a user with the bias voltage of the drive to generate a comparison result signal; a switching controller for generating a switching signal upon receiving the comparison result signal from the feedback controller; and a bias voltage regulator for charging/discharging the input voltage according to the switching signal received from the switching controller so that it can adjust the bias voltage of the drive.
