Abstract: A novel additive comprising an oxamide additive with long chains is described herein. The additive can be incorporated into a thermoplastic polymer to form a thermoplastic polymer composite. The additive modifies the surface of the thermoplastic polymer to render the oil, water or dust repellent properties to the thermoplastic polymer composite.

Abstract: Accordingly, the present disclosure provides an air conditioner including an evaporator, an expansion valve, a compressor, and an evaporative condenser through which refrigerant circulates, comprising: an outdoor unit in which the evaporative condenser is disposed; an indoor unit in which the evaporator is disposed; and a control unit connected to the indoor unit and the outdoor unit; wherein the evaporative condenser includes a cooing flow path through which a refrigerant passe and a condenser injection water module providing water to the cooling flow path, the outdoor unit includes first control valve for controlling water supplied to the condenser injection water module, and the control unit is connected to the first control valve and the evaporative condenser, and changes the amount of water supplied through the first control valve according to operating conditions.

Abstract: A system for customized prediction of a menstruation period or a fertility period is provided. The system includes a vital information measurer for measuring vital information about a user, a basic menstruation information generator for calculating the first day of menstruation or an ovulation day using the vital information received from the vital information measurer and outputting the first day of menstruation or the ovulation day as basic menstruation information, a menstruation cycle modeler having a menstruation cycle model representing a menstruation cycle as a function with a predetermined period, and a model parameter estimator for estimating and compensating a menstruation cycle parameter of the menstruation cycle model using the basic menstruation information received from the basic menstruation information generator.

Abstract: Transmission-type screens are placed corresponding to a display board at a front area of the display board, on which an article is placed. Each of the screens transmits and projects a projector image luminous flux projected from a backside of the screens to a front side of the screens. When the projector image luminous flux is projected from the backside of the screens, each of inner circumferences which defines a space including an image projecting space for leading the projector image luminous flux to the backside of the screens without obstruction. A display shelf might have a projector and a computer. The projector projects the projector image luminous flux. The display shelf might have a reflecting mirror which lead the projector image flux to the screens.

Abstract: An automatic car lamps lighting controller to provide warning light in the daytime as well as in the night. The system includes an induction coil for detecting the start up of the car engine, an amplifier circuit, a comparator, control relays, and a night control circuit. As soon as the car is started, the front and the rear location lamp of the car being automatically turned on; the car front lamps and dash lamps automatically turned on in the night. The system enables the instant vehicle (car) to be readily seen by the drivers of other vehicles even though the driver of the instant vehicle neglects or refuses to manually turn on the road illumination lamps or vehicle location (parking) lamps.
