Abstract: PURPOSE: A controlling method of a BLDC motor(300) is provided to reduce cost and optimize PCB size by reducing the number of Hall sensors(Ha,Hb,Hc)s. CONSTITUTION: A controlling method of a BLDC motor(300) includes following steps. In the first step, when an interrupt signal is generated in response to the change of state of Hall sensors(Ha,Hb,Hc), the primary, secondary and tertiary timers are initialized and put into stand-by. A state flag for a sequence control of the Hall sensors(Ha,Hb,Hc) is loaded to RAM. Then it is decided whether a motor(300) is at the starting stage. In the second step, if the motor(300) is at the starting stage, the state value of the Hall sensors(Ha,Hb,Hc) is read for initial starting and the primary timer is operated. After logic corresponding to the initial state value is output, the distance value(T2,T3) between modes corresponding to 60 and 120 degrees based upon the distance value(T1) between modes(90 degrees) is saved in the RAM and returned. In the third step, if the motor(300) is not at the starting stage at the first stage, the location of a rotor by reading the initial state value of the Hall sensors(Ha,Hb,Hc) is decided. The secondary and tertiary timers are operated, and it is decided whether the values of the secondary and tertiary timers are identical with T2 and T3. In the fourth step, if the values of the secondary and tertiary timers are identical with T2 and T3, the timing of the current output signal is compensated and generated. In the fifth step, if the values of the secondary and tertiary timers are not identical with T2 and T3, the timing of the current output signal is generated without compensation and returned.

Abstract: 본 발명은 건물 급수용 자동 공기압 급수장치에 관한 것으로서, 지상이나 지하에 설치된 저수조(11)에 저장된 물을 흡입배관(19)을 거쳐 펌프(22)를 이용하여 건물 각층의 분배관(15)(16)(17)으로 송출하는 급수 시스템에 있어서:  상기 메인급수관(12)은 펌프(22)의 하류에 설치되고, 공기압을 받는 상태로 물을 저장하는 기압탱크(25);  상기 메인급수관(12)은 펌프(22) 하류에서 분기되고, 상기 기압탱크(25)의 일측에 연결되는 토출배관(13);  외부의 공기를 보급받기 위한 급기관(14)과 연통되는 상태로 상기 토출배관(13) 상에 설치되는 공기보급조(23);  상기 메인급수관(12)과 분배관(15)(16)(17) 상에 각각 설치되고, 급수 압력을 조절하는 복수의 감압밸브(32)(36)(37); 그리고  상기 기압탱크(25)의 압력이 소정치 이하임을 검출하면 펌프(22)를 작동하고 펌프(22) 정지후 일정시간 동안 급기관(14)을 개방하여 공기보급조(23)로 외부의 공기가 유입되도록 제어하는 콘트롤패널(30)을 포함하여 이루어지는 것을 특징으로 하여, 각 존(ZONE)별로 균일한 수압이 유지되도록 하는 동시에 옥상 물탱크가 없어지므로 건물의 하중이 증가되는 것을 방지하고 건물의 내부 공간에 대한 활용성을 향상하는 효과가 있다.

Abstract: PURPOSE: A main shaft for a machine tool using composite is provided to replace a steel sleeve part of the composite main shaft having weak dynamic and thermal characteristics with another composite sleeve having excellent dynamic and thermal characteristics and vibration damping efficiency and to improve the dynamic and thermal characteristics of the composite main shaft by strengthening the composite surface characteristic with ceramic coating. CONSTITUTION: A main shaft(500) for a machine tool using composite includes a hollowed composite main shaft part(510) made of composite and steel sleeves(520) coupled at both ends of the composite main shaft part with an adhesive to reinforce both ends of the composite main shaft when a bearing is mounted. The composite sleeves serving as a reinforcement in substitute for the steel sleeves are coupled to the peripheries of both ends of the composite main shaft. The composite sleeves are coupled firmly to the composite main shaft by surplus resin produced during hardening.

Abstract: PURPOSE: An air dispersion plate and a nozzle for an incinerating furnace of a flowing layer and a method for aligning the nozzle are provided to differently supply air flow by differently aligning the nozzles on the dispersion plate per layer for forming a circulation flow in the respective layers and removing incombustible substances fallen on the dispersion plate out of the furnace speedily. CONSTITUTION: In an air dispersion plate and a nozzle for an incinerating furnace of a flowing layer and a method for aligning the nozzle, the furnace is formed in the shape of a square or a circle, and the dispersion plate have dispersion nozzles which are disposed more at a part around a discharge hole and less at a part far from the discharge hole or have an opening of which size is different from each other in the range of 3mm to 42mm, so that the nozzles are disposed uniformly in the interval in the traverse or radial direction and differently in the longitudinal or peripheral direction in the distance between the nozzles, and numbers and areas of the nozzles.
