    • Provided is a treadmill-related technology. That is, the treadmill device and the operating method of the same is configured to detect a user who is taking exercise in real time, take pictures of the detected user's looks, and insert user image data as the results of data analysis, which are obtained from the taken pictures, into a virtual 3D object moving image which indicates the selected exercise course background, so as to project a 3D user image in which the user's behavior patterns are engaged with a virtual 3D object moving image. Therefore, since the treadmill device is used to allow a user to see his own looks taking exercise in real time, it is possible to prevent the user from feeling boring during exercise, and it is easy to continuously check the user's own physical status or conditions. Also, since a user may actively employ exercise course backgrounds which are freely changed during exercise by the user's choices, the best information on the physical rhythm and exercise conditions may be offered to the user, thereby improving the user's satisfaction and buying power, which leads to an expected increase in the sales.

    • A disc player performs disc loading and ejecting while closing and opening the player lid. The disc player includes a housing having a first guide groove longitudinally formed on an inner side thereof, a deck including a turntable, a moving plate mounted over deck to horizontally move in frontward and rearward directions, a disc tray engaged with the moving plate and for loading and ejecting a disc onto and out of the turntable while vertically moving down and up in response to rearward and frontward movements of the moving plate, a lid engaged with the housing to pivotally close and open, and movement mechanism for controlling the frontward and rearward movements of the moving plate when the lid closes and opens. A simple structure and miniaturization of a disc player can be accomplished since disc loading and ejecting is performed without using a motor and gears.

    • A high speed tool steel and a manufacturing method therefor are disclosed, in which carbides are formed in the matrix in a uniform manner, thereby obtaining a high toughness and a high abrasion resistance. The high speed tool steel according to the present invention includes a basic composition of WaMobCrcCodVxCyFez where the subscripts meet in weight %: 5.0%≦a≦7.0%, 4.0%≦b≦6.0%, 3.0%≦c≦5.0%, 6.5%≦d≦9.5%, 2.2% ≦x≦8.3%, 1.1%≦y≦2.18%, and 66.52%≦z≦73.7%. The final structure has carbides uniformly distributed within a martensite matrix, which are mainly MC and M6C carbides. The method includes the steps of melting the above-defined alloy composition, gas spraying the melted alloy to form a bulk material, heat treating the bulk material to decompose the M2C carbides to stabilize M6C carbides and hot working the heat treated bulk material to a desired shape.
