Abstract:
PURPOSE: A frame pattern forming roller and a manufacturing method thereof are provided to express realistic texture on a rolled material by forming regular and irregular grooves on the forming roller. CONSTITUTION: A frame pattern forming roller(1) comprises a plurality of grooves formed lengthwise on the exterior. The grooves include vertical grooves(11) formed lengthwise at regular intervals and irregular grooves(12) irregularly formed on the exterior of the pattern forming roller. While a synthetic resin forming material passes through between a lower roller and the pattern forming roller, the pattern is carved on the upper surface of the forming material.
Abstract:
A chamber system for measuring a gas emission velocity with a semiconductor sensor is provided to calculate the diffusion speed and the discharge amount of foul odors and volatile organic materials to control the air pollution material. In a chamber system, the bottom surface of the chamber is formed of a slidably opened and closed door so as to inject a contamination gas into the chamber. A lower semiconductor gas sensor is installed at a central portion of the interior space by a chamber wall surface or a fixation unit. An upper semiconductor gas sensor is installed at a central portion of the interior space by a chamber wall surface or a fixation unit at a height from the lower semiconductor gas sensor.

A signal connection unit(7) connects the microphone unit(5) and the speaker unit(6) to the transceiver(8). A control switch(4) controls the transceiver(8). A short circuit(1) is composed in the control unit(4). A protection circuit(2) is composed in the control switch(4). A conductive knob(3) connects to the short circuit(1).
Abstract:
PURPOSE: A controller of a booster is provided to prevent unnecessary discharge of a booster by controlling the booster when an electronic device is not used or operate the booster during a program period of the electronic device when the electronic device is used. CONSTITUTION: A booster(2) is operated only when an electrical change is generated from a CE pin(12). A power supply source(1) is used for supplying voltage to the booster(2). An input switch(5) is used for transferring the electrical change to an input part of a program IC(3) and the CE pin(12) in order to operate the program IC(3). The program IC(3) operates the booster(2) by transferring the electrical change to the CE pin(12) through a control portion(13) when receiving boosting voltage from the booster(2). In addition, the program IC(3) checks a state of the input switch(5) and a state of an electronic device(4) in order to operate the electronic device(4) and intercepts the electrical change of a control portion(13) in order to stop an operation of the booster(2).
Abstract:
PURPOSE: An advertisement apparatus for significant information using a load object is provided to enable a user to tactually as well as visually recognize some advertisement containing significant information of the load object. CONSTITUTION: The advertisement apparatus for significant information comprises a movable load object(4) that the center of gravity is applied to the center of the earth when a user lifts it; a grip portion(2) connected with the load object through a fastening connector(5) to allow a user to lift the load object without gripping the load object directly; and an advertisement display part(1) containing significant information about the load object, which is located at a portion to be contact with the thumb of the user.
Abstract:
본 발명은 하기 일반식(1)으로 표시되는 니페코틸-2-피롤리디논 및 약제학적으로 허용되는 그의 염 및 이를 유효성분으로하는 항경련제에 관한 것이다.
본 발명에 따른 물질은 아미노산 계열의 화합물인 γ-아미노부틸산(GABA)와 γ-아미노부틸산 유입억제제(GABA uptake inhibitor)중 하나인 니페코산(nipecotic acid)을 결합시켜 아마이드로 변형시켜, 본래의 물질보다 지용성을 증가 시키므로서 BBB통과를 용이하게 하고, 흡수된 후에는 생체내 효모에 의해 분해되어 γ-아미노부틸산(GABA)과 γ-아미노부틸산 유입억제제(GABA uptake inhibitor)로서 작용가능한, 즉 두가지의 활성을 보이는 물질로 그 적용이 매우 광범위한 항경련 활성을 나타낸다.
