Abstract: Provided is an integrated-system simulation system obtained from a simulation system having a command, control, and communication (C3) system of systems (SoS). The integrated-system simulation system includes an abstracted command and control (C2) model including a traffic model including inter-node traffic information transferred according to time, a mobility model including position information of nodes, and an interface model making the traffic model and the mobility model interoperate, and a communication (C) model configured to be combined with the abstracted C2 model so as to interact with the abstracted C2 model in a full-duplex manner. The abstracted C2 model is generated by acquiring traffic and mobility data between the C2 model and the C model of the SoS simulation system, hypothesizing a form of the abstracted C2 model, and learning the traffic and mobility data acquired from the SoS simulation system and determining variables of the abstracted C2 model form.

Abstract: Disclosed herein is a multifunctional therapeutic device with educational and entertainment functions, including a body including a program engine and a power supply unit. The multifunctional therapeutic device includes a data storage unit, an image display unit, and a sound output unit. The data storage unit is removably mounted on the body, is electrically connected to the program engine, and temporarily stores image and sound output data. The image display unit is mounted on the remaining side of the body so that its angle can be adjusted, is electrically connected to the program engine, and outputs an image through the program engine. The sound output unit is mounted between the data storage unit and the image display unit, is electrically connected to the program engine, and outputs a sound through the program engine. The image display unit and the sound output unit are operated separately or in combination.

Abstract: The present invention relates to a post cap for a guardrail equipped with light emission means. The post cap for a guardrail is configured to produce beautiful scenery through variation in the color and the blinking state and to ensure safe nighttime passage through the transmission of signals depending on situations. The post cap for a guardrail equipped with light emission means capable of emitting light of various colors is configured to detect the location of installation and time through the reception of GPS signals and to enable a plurality of post caps to implement variations in color in conjunction with each other through time-based variations in color according to a stored program based on the location of installation.

Abstract: An ultrasonic cleaning tank with an ultrasonic vibrator mounted on its bottom is supplied with an aqueous cleaning solution which has been deaerated to a predetermined dissolved oxygen content ranging from 0.01 to 5 ppm. A workpiece to be ultrasonically cleaned is then immersed in the cleaning solution. Thereafter, the ultrasonic vibrator radiates ultrasonic energy into the cleaning solution to remove foreign matter and burrs off the workpiece.

Abstract: A treatment vehicle for treating empty vessels such as empty bottles. A feed conveyor for carrying empty vessels introduced in a vehicle body is obliquely provided such that a starting end thereof faces to a rear of the vehicle body and a forward end thereof rises toward a front of the vehicle body. A treatment machine for treating the empty vessels to produce chips is provided beneath the forward end of the feed conveyor, and a hopper for receiving the chips produced by the treatment machine is provided in a space formed beneath the feed conveyor. A transport conveyor for transporting and guiding the chips from the treatment machine into the hopper is obliquely provided in a direction opposite to the feed conveyor, and the hopper is provided in the shape of a trapezoid in an angular space surrounded by the feed conveyor and the transport conveyor.

Abstract: Disclosed is a spray type ultrasonic washing apparatus using a coaxial nozzle structure which is composed of inner and outer hollow frustums for supplying deaerated washing liquid in the annular passage delimited by the outer and inner frustums and supplying nondeaerated washing liquid in the inner frustum, thus permitting deaerated washing liquid to be enclosed by nondeaerated washing liquid in spraying against work to be washed, thereby isolating deaerated washing liquid from the surrounding atmosphere to prevent invasion of air into the deaerated washing liquid. Thus, cavitation can be formed effectively in the deaerated washing liquid, and washing can be performed at an increased efficiency.

Abstract: Disclosed is an improvement of ultrasonic washing apparatus comprising at least one washing vessel, an ultrasonic vibrator for radiating ultrasonic wave into the washing bath, an oscillator for operating the ultrasonic vibrator and degassing means for removing dissolved air and other gases from the washing liquid, thereby enhancing cavitation in the washing bath when the ultrasonic wave is radiated therein, said degassing means including gas separating means and barrier means for preventing surrounding air from dissolving into the washing liquid while it is degassed. Thanks to deaeration in the washing bath cavitation can be used to its full extent in removing soil from a soiled object in the washing bath.

Abstract: Disclosed is an improvement of ultrasonic cleaning system equipped with degassing means or boiling vessel to remove gases from cleaning liquid for activating the formation of cavitation in the cleaning bath. The ultrasonic cleaning system is improved according to the present invention in that the boiling vessel is used to supply the degassed liquid to the cleaning vessel to form a high-temperature zone on the cleaning bath, and that a circulation conduit is provided to supply the cleaning liquid from the high-temperature zone to the bottom of the cleaning vessel. The improved structure permits the creation of a high-temperature zone and a low-temperature or cleaning zone in one cleaning vessel, thereby preventing the dissolution of surrounding gases into the cleaning liquid, and at the same time, subjecting objects to ultrasonic-cleaning at a controlled temperature which is appropriate for ultrasonic cleaning, thereby improving the cleaning effect, and hence the cleaning efficiency.
