Abstract:
A wireless nursing system is provided to enable a nurse or a protector to take care of a patient or an infant efficiently by wirelessly transceiving urine/feces information of the patient or the infant wearing a diaper. A diaper(100) is equipped with a sensor(110) for detecting the increase of moisture. A signal processor(200) generates and transmits a wireless signal if the sensor detects the moisture increase of the diaper. An output part(300) outputs information for the moisture increase of the diaper by receiving the wireless signal. The sensor includes a first and second metal gauze plate, and a paper facing one side to the first metal gauze plate, facing another side to the second metal gauze plate, and conducting current between the metal gauze plates if the moisture is over a predetermined value. The metal gauze plate includes an electric wire projected outside the diaper. The signal processor includes a plastic clip equipped with a metal plate at the inside. The sensor and the signal processor are connected by clipping the electric wires with the clip.
Abstract:
The present invention relates to an ultra-rapidly hardening concrete composition using modified emulsified asphalt and a bridge deck pavement technique using the same and, more particularly, to an ultra-rapidly hardening concrete composition using modified emulsified asphalt and a bridge deck pavement technique using the same, wherein a re-emulsification type power resin is added to ultra-rapidly hardening cement to ensure durability and flexural tensile strength and a synthetic polymer is added to emulsified asphalt so that cement mixing properties, tensile strength, adhesiveness, durability and operability are improved. The ultra-rapidly hardening concrete composition using the modified emulsified asphalt according to the present invention contains 16 to 26 wt% of ultra-rapidly hardening cement binding material; 26 to 56 wt% of fine aggregate; 25 to 55 wt% of thick aggregate; 1 to 5 wt% of re-emulsification type powder resin; 1 to 10 wt% of water; and 1 to 30 wt% of modified emulsified asphalt.

PURPOSE: A vertical water tube type once-through steam boiler is provided to cleanly clean a heating surface, to improve a quality of superheated steam, to increase the temperature of hot water, and to rapidly generate hot water. CONSTITUTION: A vertical water tube type once-through steam boiler includes a steam boiler body (10), a heat exchanger (20), and a heating surface cleaning member (30). The steam boiler body forms a steam chamber (11) on the upper part and a water chamber (12) on the lower part and forms a combustion chamber (15) on the central part by installing at least one water pipe wall (13a, 13b). The heat exchanger is installed on the upper part of the combustion chamber and includes an inlet conduit (21) connected to a saturated steam conduit (18) of the steam chamber. The heating surface cleaning member includes a superheated steam distribution pipe (31) and a plurality of spraying pipes (33). The superheated steam distribution pipe is connected to an outlet conduit (22) of the heat exchanger and is installed on the top surface. The spraying pipes are installed by penetrating through the steam chamber and the superheated steam sprayed to a heating surface of the steam boiler body.
