Patent KR-940009681-B1 (KR)
Title: Improvement to two stroke internal combustion engines and implementation method
Inventor: MELCHIOR JEAN F
IPC: F02D13/02
Filed: 1986-11-05
Granted: 1994-10-15
Abstract: The engine, operating on the two-stroke cycle, is characterised in that the admission and exhaust distributing elements are valves (7, 9), their control elements being sensitive to a parameter such as the speed of rotation of the engine, the fuel consumption, the supercharging pressure value, the difference between intake and exhaust pressure, in order to vary the angular opening and closing position of the valves (7, 9) to ensure that a sufficient quantity of fresh air is admitted into the working chamber, under the least favourable conditions, in particular by opening the intake during a period when the volume of the chamber is increased. <IMAGE>

Abstract: 본 발명은 태양 전지의 제조 방법에 관한 것으로서, 단파장의 흡수 특성을 향상시키고 접촉 저항을 감소하여 전자-정공 쌍의 재결합을 방지하여 효율을 증대 시키는데 적합한 것이다. 
     종래에는 n + 층(2)의 두께가 얇아 전극으로 인해 n + 층(2)이 파괴되고 TiO 2 반사 방지막층(3)을 전극이 뚫고 통과하여 접촉저항이 증가 하였으며, 후면에는 전자-정공쌍의 재결합이 발생되는 문제점이 있었으나, 본 발명은 전면 전극부를 두번 도핑하여 전극의 접촉 저항을 감소시켜 도핑층의 파괴를 방지하고 저늑 이외 부분은 한번 도핑하여 단파장광 흡수 특성을 증가 시켰으며 전후면에 SiO 2 로 무저항층(10)을 형성하여 표면에서 전자-전공쌍의 재결합을 방지하였으며 후면에 BSF 를 형성하여 전자의 역류를 방지함으로서 태양전지의 효율을 증대시키도록 한 것이다.

Title: Catalyst system and process for hydrotreating hydrocarbons
Inventor: SULLIVAN RICHARD F

Abstract: This invention provides a layered catalyst system for hydro-denitrification of hydrocarbons, such as vacuum gas oil, used for hydrocracking to produce various fuels. The layered catalyst system of this invention comprises a first layer of a nickel-molybdenum-phosphorus/alumina catalyst or a cobalt-molybdenum-phosphorus/alumina catalyst and a second layer catalyst comprising a nickel-tungsten/silica-alumina-zeolite or a nickel-molybdenum/silica-alumina-zeolite catalyst. The preferred aspects of the combination of the layered catalysts disclosed herein are: (a) the first layer alumina catalyst has a molybdenum content greater than about 14% by wt.; (b) the first layer alumina catalyst has a relatively large pore size, such as at least about 60  ANGSTROM ; and (c) the second layer catalyst contains at least about 2% of a zeolite component. The layered catalyst system of this invention and the attendant process produces improved denitrification of feedstocks, improved catalyst life and other advantages.
