Abstract: In a shore reclamation area for fill-in despoasal  of  wastes which is separated by a sea bank (2) between the shore reclamation area (1) and the open sea (5), the sea  bank  (2)  is  constructed such that a  water  level  adjustment  installation  maintains  a certain water head difference between the open sea and  the  water level in the shore side land so as for the water  seepage  through the bank to occur only toward the land  from  the  sea,  thus  not allowing any seepage of dissolved pollutants toward the  sea  from the waste fill- in. Also, the fill-in of waste from the  bank  side first and then toward the land helps the seepage towards the  land and against the sea by the rule of Darcy Law.

Title: High density thermal spray coating apparatus and process
Inventor: MOSKOWITZ LARRY NEIL
IPC: B05B7/20
Filed: 1988-12-27
Granted: 1996-10-10
Abstract: An attachment for supersonic thermal spray equipment by which inert shield gas is directed radially outwardly about the central core of a supersonic, particle-carrying flame to isolate the same from ambient atmosphere. The shield gas is injected tangentially against the inner surface of a constraining tube attached to and extending from the discharge end of the thermal spray gun nozzle, causing the shield gas to assume a helical flow path which persists until after it exits the tube and impacts the work piece. A process using the shielding apparatus with a high-velocity, thermal spray gun and employing oxygen and hydrogen as gases of combustion and inert gas to introduce metal powder, having a narrow particle size distribution and low oxygen content, into the high-velocity combustion gases, produces significantly improved, high-density, low-oxide metal coatings on a substrate.

Title: Switching mode power supply
Inventor: LEE CHANG-HUM
IPC: H02M1/32
Filed: 1989-06-29
Granted: 1991-07-29
Abstract: When a first power (V1) is over voltage, a zener diode  (ZD2) is turned on by its over voltage. Then the current flows through a photo diode (P6) of a photo relay (PR1) and  triggers  a  SCR.  At this time the zero voltage is applied to an inverse  tap  (PI)  of the PWM generation IC so that the operation of the IC is  stopped. In case of a second power  (V2),  the  same  process  is  repeated through a zener diode (ZD3) so that the system is shut down.  When the over current flows through a transformer (TOC1)  as  the  over current sensor, the voltage level of the secondary part  is  risen up and turns on the zener diode (ZD1) so that the system  is  shut down in the same way.

Abstract: 본 발명은 샘플/홀더를 이용한 다축서보 제어방법에 관한 것이다. 
     종래에는 다축 로보트를 제어하기 위해서는 축수에 해당하는 DAC가 필요하여 가격이 상승하여 제어축수의 확장과 성능향상을 위해서는 비용상승을 감수해야만되는 문제점이 발생되는 바, 본 발명에 의하면 마이크로 프로세서(10)에서 출력하기를 원하는 데이터를 우선 DAC(20)에 기입한 후 원하는 축의 서보에 아나로그 신호를 전달하기 위하여 샘플/홀더를 선택한다. 
     즉, 하나의 DAC(20)와 샘플/홀더(30)를 이용하여 다축 서보를 효과적으로 제어하고 성능향상과 동시에 단가를 절감시키게 된 발명인 것이다.
