Granted: 2019-08-13
Abstract: The present invention relates to a metal soap which is used when removing smells of garlic, onion, fish and the like on hands of a cooker during food cooking. More specifically, although an existing metal soap has mainly been manufactured of stainless steel, the present invention has manufactured a bronze soap containing silver and selenium to have not only sterilizing, antibacterial and nontoxic functions but also an active oxygen removal function and an antiaging function such that the manufactured bronze soap can perform a sterilization process as well as removing the smells on the hands. In order to achieve the purpose, the present invention manufactures a bronze soap comprising silver and selenium by mixing 78 wt% of copper (Cu), 21.4 wt% of tin (Sn), 0.2 wt% of silver (Ag) and 0.4 wt% of selenium (Se) based on the total weight of the mixture. The present invention enables a beautiful silver-white color sense of silver (Ag) and active oxygen-removing and antiaging functions of selenium (Se) to be obtained by mixing small amounts of silver (Ag) and selenium (Se) with bronze. Further, the bronze soap comprising silver and selenium has a high hardness value, thereby being used semi-permanently. As described above, the bronze soap is devised to obtain active oxygen-removing and antiaging effects and an increased aesthetic sense by mixing silver (Ag) and selenium (Se) with sterilizing, antibacterial and nontoxic properties, bronze′s intrinsic properties.

Abstract: Disclosed is a PSC beam manufacturing method for forming a rebar assembly by connecting prefabricated segments of the rebar assembly on site. When the PSC beam is manufactured to construct a PSC bridge, a plurality of segments of the rebar assembly can be manufactured by use of a rebar assembling stand at a factory remote from the site, and can be easily transported to the site. After the segments of the rebar assembly are connected to form the rebar assembly on site, concrete is deposited and a tensile force is applied thereto to easily manufacture the PSC beam. Since the segments of the rebar assembly are assembled by the rebar assembling stand which is engaged to an integral fastening block, the segments can be precisely and quickly manufactured at the factory, and the segments can be easily connected on site, thereby remarkably reducing the number of workers and working times on site to shorten a construction period, and manufacturing the inexpensive PSC beam of high quality.

Abstract: 차량용 제동장치에 대한 발명이 개시된다. 개시된 차량용 제동장치는: 페달부의 가압에 의해 유압을 생성하며, 제1탄성스프링과 제2탄성스프링을 구비하여 저답력 구간에서 페달필을 구현하는 제1마스터실린더부와; 제1마스터실린더부로부터 유압을 전달받아 구동되는 전기구동부와; 전기구동부의 구동력을 전달받아 제동유압을 생성하는 제2마스터실린더부와; 제2마스터실린더부로부터 유압을 전달받아 제2마스터실린더부의 제동압력을 제어하며, 브레이크 액이 통과되는 유로부와, 유로부에 위치되며, 휠 실린더에 형성되는 유압을 감압하도록 개방되는 아웃렛 밸브와, 브레이크 액이 저장되는 저압 어큐뮬레이터를 포함하는 제동시스템부;를 포함하고, 아웃렛 밸브의 개방시 휠 실린더의 브레이크 액이 아웃렛 밸브의 개폐부가 개폐하는 아웃렛 밸브의 유입구 측으로 유입되어 아웃렛 밸브의 배출구를 통해 저압 어큐뮬레이터로 배출되는 것을 특징으로 한다.
