Title: Method for preparing polyethylene wax by gas phase polymerization
Inventor: MAIN CHANG
IPC: C08F2/34
Filed: 1989-11-01
Granted: 1998-05-01
Abstract: This invention relates to a process for preparing polyethylene wax having a narrow molecular weight distribution in a gas phase polymerization reactor. The invention particularly relates to the process of polymerizing ethylene in the presence of a supported metallocene-alumoxane catalyst and hydrogen. The catalyst may be derived from the addition of silica gel containing about 6 to about 20 percent by weight adsorbed water to a trialkylaluminum solution. An alumoxane coated silica gel is formed to which a metallocene may be added and the resulting material dried to free flowing powder. A trimethylaluminum pretreated metallocene may be employed when the trialkylaluminum is selected from the group consisting of triethylaluminum, tripropylaluminum, tri-n-butyl-aluminum, tri-isobutylaluminum, tri(2-methylpentyl)aluminum, trihexylaluminum, tri-n-octylaluminum and tri-n-decylaluminum.

Granted: 1993-07-07
Abstract: The method obtains images  atomatically  inputted  through  a camera to extract the accurate coordinates of the holes in the PCB bear board. The PCB bear board (11) is attached to a  PCB  carrier shaft (13) provided between a slit lighting (14) and  a  line  CCD camera (15), the board (11) being fixed to the shaft by  a  fixing member (12) to be moved by a motor (16). The camera (15)  captures the image of the hole in the board (11) lighted by the  beam  from the light (14) for the hole image signal to be A/D converted  into digital image signal through an image  gaining  member  (17).  The obtained digital image data is stored in a memory (18) and also is given to an X and Y coordinate data extracter (20) for finding the coordinates of the hole position to  be  stored  in  a  data  base storage (22) and verified by the eyes on a monitor.

Title: Device seperating method of semiconductor apparatus
Inventor: KIM YONG-BAE
IPC: H01L27/04
Filed: 1991-08-22
Granted: 1993-09-16
Abstract: The method prevents the channel  stop  ion  expanded  by  the thermal oxidizing process to expand below to the  silicon  nitride layer so that much more channel stop ion than the case without the silicon nitride layer is collected between the  element  isolation region and the silicon substrate. Then  the  electrical  isolation between two elements is performed exactly.  For  example,  if  the neighbouring NMOS transistors are formed  on  the  substrate,  the punch through voltage of the impurity diffusion layer is increased so that the element characteristic is improved.

Granted: 2001-04-02
Abstract: 본 발명에 따른 동적집속장치는 단순한 배치로서 화면스크린의 주위에서 빔초점의 왜곡을 감소시키고 초점화를 개선하는 것이고, 고저항치저항(R)와 다이오드(D)의 병렬회로가 저전압측전극판(3)(4)와 양극절압(HV)이 인가되는 고전압측전극판(1)(2)의 사이에 접속되고, 음극선관의 엔빌로프 유리가 유전물질로 사용되어 칼라 텔레비젼의 음극선관 엔빌로프에 내외측으로 전도층을 코팅하여 컨덴서(C)를 형성하고, 수평 수직 포물선파형에 의해 양극전압(HV)보다 아주낮은 DC전압을 진폭변조하므로서 제공되는 변조된 전압의 수평 블랭킹기간에 수직 포물선파형전압을 더해서 야기되는 집속전압이 통상 컨덴서(C)의 일단측(음극선관 엔빌로프 외부측)으로부터 저전압측면 전극판(3)(4)에 인가되는 구성으로된 것이다.

Title: Method of hot rolling steel slab
Inventor: CHON MYONG-SHIK
IPC: B21B1/26
Filed: 1993-11-09
Granted: 1995-09-01
Abstract: The hot-rolling operation for steel slabs improves the pressing of slab with by setting an edger roll gap. The hot-rolling operation comprises: (A) controlling width rolling reduction of the first pass based on the load distribution of the edger roll; (B) calculating width rolling reduction of each pass from the final desired width of the slab; and (C) setting the edger roll gap using width rolling reduction, slab width and elastic recovery.

Title: Junction formation method
Inventor: HWANG JOON
IPC: H01L29/94
Filed: 1993-12-28
Granted: 1997-05-30
Abstract: A method is described that can selectively implant B11 into a silicon substrate which is generated when 49BF2+ is implanted thereto and thereby conflicted to other grains. An oxide layer for a implant buffer is formed on the surface of a silicon substrate. Thereafter, a shallow junction is made by implanting only B11 into the silicon substrate which is generated by the confliction of BF2+ and other grains when BF2+ is implanted by a predetermined vacuum degree and energy. The oxide layer has the thichness capable of absorbing all of implanted BF2+ ions. The vacuum degree and energy are controlled so that a dissociation is occurred when the BF2+ is implanted and thus conflicted to other grains. Thereby, it is possible to form the shallow junction which is required in a highly integrated MOS device.

Title: Autoadhesive tape for corrosion and electrical protection of metal pipes, process for manufacturing, protection system and process for applying the same
Inventor: CÎRLAN NICOLAI
IPC: C09J7/02
Filed: 2002-02-05
Abstract: The invention relates to an autoadhesive tape for the corrosion and electrical protection of buried metal pipes, consisting of non-corroding protecting film onto which a permanent adhesive is applied. The protection film may be doubled with a support for mechanical and sunshine protection. There are also presented the process for manufacturing the autoadhesive band, a protection system and a process for applying thereof onto the pipes.

Title: Optical system for taking over the image from a sighting telescope
Inventor: GRANCIU DANA
IPC: G02B9/34
Filed: 2009-08-25
Abstract: The invention relates to an optical system included in an optical device for taking over the image from a sighting telescope, said optical system being attached to the eye-piece thereof, having the role of picking up the image formed by means of the telescope and of remotely transmitting it, allowing, at the same time, the direct observation through the sighting telescope. According to the invention, the optical system is formed of a dividing blade (2), an element (3) for deviating the optical axis at an angle of 90°, which may be a prism or a mirror and an objective (4) focussing the images formed through a sighting telescope (1) on an optical sensor (5) of a video-camera (6), the objective (4) including a positive frontal lens (L1) and a negative doublet (D1), a second positive or negative doublet (D2) and a positive lens (L2).
