Abstract: The present invention relates to a method and apparatus for manufacturing a bullet charged with compressible composite explosives, process of the method comprising: 1) particle explosives is measured using constant quantity supplying device and is charged to a pallette mold; 2) the particle explosives is transferred to pellet-forming mold and then the particle explosives of the pellet-forming mold is molded under constant pressure to a pellet; 3) the pellet-forming mold is transported to the upper side of the bullet body fixing mold, thereby exiting the pellet of the pellet-forming mold, and the pellet which is inserted to the bullet of the bullet body fixing mold is pressed under constant pressure for charging; 4) the bullet with the pellet completely charged is transported to the bullet separating device; and 5) excess explosives is removed through cutting from said bullet.

Abstract: Disclosed are an apparatus and method for loading small and medium caliber cartridges with pressable plastic bonded explosives (PBXs). A plurality of pellets are pre-formed to have a high density, and are loaded into a small and medium caliber cartridge one by one. Accordingly, a high and uniform density is obtained. And, when manufacturing small and medium caliber cartridges, the pressable PBXs are anticipated to be massively loaded into the small and medium caliber cartridges in the future.

Abstract: An advanced wire/wireless keyboard for use in a computer system, which comprises a user ID (identification) setting function. When the keyboard operates with wireless communication, the keyboard controller allows delivery of the user ID information, to which an keyboard data signal is added, to the computer main unit 10. With this keyboard, the noise generation is prevented by generating a specific wireless signal corresponding to the user ID information. The keyboard has a rechargeable battery and a battery charging circuit for charging the rechargeable battery during wire communication for subsequent use during wireless communication.

Abstract: A method and device for controlling a CPU stop clock interrupt of a computer system. The device includes an idle detector and a control processor. A CPU having a stop clock interrupt mode receives a stop clock interrupt signal and sets up and clears the stop clock interrupt mode according to a logic state of the stop clock interrupt signal. The control processor receives a signal representing an idle condition of the computer system from the idle detector, a signal for enabling idle detector control of the CPU stop clock interrupt mode and a signal for forcing the CPU to resume a normal mode by clearing the stop clock interrupt mode. The idle condition can be defined by a computer user according to a selection of predetermined times during which no user inputs are received by the computer system.

Abstract: A method and device for controlling a CPU stop clock interrupt of a computer system. The device includes an idle detector and a control processor. A CPU having a stop clock interrupt mode receives a stop clock interrupt signal and initiates and terminates the stop clock interrupt mode according to a logic state of the stop clock interrupt signal. The control processor receives a signal representing an idle condition of the computer system from the idle detector, an alternate signal for idle detector control of the CPU stop clock interrupt mode, and a control signal for forcing the CPU to resume a normal mode by clearing the stop clock interrupt mode. The idle condition can be defined by a computer user according to a selection of predetermined times during which no user inputs are received by the computer system.

Abstract: A peripheral device input-initiated resume system for a combined hibernation system and back-up power supply for a computer comprises a keyboard controller for inputting an appropriate signal to the operating condition based on the key selected by a user, a power management system for outputting a wake-up signal if the signal is inputted from the keyboard or other input devices, a data back-up power unit for supplying DC voltage in case the power is cut-off suddenly or a user does not use the computer for a predetermined time, a power supplying unit in which a switching-mode power supply SMPS converts the external source AC power at line voltage into DC power at a desired voltage and supplies that power to each device on the main board of the computer, thereby retrieving the previous work again by cutting off power of all devices, once the power is off or when a user does not use the computer for a predetermined time, and supplying the additional power only to the MICOM(Micro Computer) or keyboard controller
