Abstract: For the preparation of acetic acid and acetic anhydride, methanol and methyl acetate are reacted under anhydrous conditions with carbon monoxide in the presence of a carbonyl complex of group VIII noble metals, methyl iodide, and catalyst systems containing alkali metal or quaternary organophosphonium or organoammonium acetate or iodide. The hot carbonylation mixture is depressurised, the evaporated components are added to a first distillation zone, and the remaining catalyst solution is fed back to the reaction zone. In the first distillation zone, the volatile carbonylation products are fractionally distilled; the low-boiling components methyl iodide and methyl acetate pass back into the reaction zone, and a mixture of acetic acid and acetic anhydride is obtained as a bottom product which is separated into the pure components in a second and third distillation zone.

IPC: H02M1/10

Granted: 1998-10-01
Abstract: A self-oscillating power supply circuit comprises a series arrangement of the primary winding (N1) of a transformer (TR), the main current path of a first semiconductor (T1) and a current measuring resistor (R1). The first semiconductor switch (T1) is driven by a second semiconductor switch (T2) which in its turn is controlled from a comparator (CP). The voltage across the current measuring resistor is applied to the non-inverting input (6) of the comparator (CP), a reference voltage obtained from a reference voltage source (RS) is applied to the inverting input (5). By arranging a capacitor (C2) between the output of the second semiconductor switch and the inverting input (5) of the comparator it is achieved that the first semiconductor switch rapidly turns-off at the end of the forward phase at an accurately determined current through the primary winding. By applying a lower reference voltage to the comparator at a higher mains voltage, an output current for supplying the load (L), which current is substantially independent of the mains voltage, is obtained from the secondary winding (N2) of the transformer.

Abstract: 본 발명은 반도체 또는 광학 장치 제조처리시 화학적/기계적 평탄화 종검 검출용 장치 및 원위치 모니터링 기술을 제공한다. 반도체 또는 광학 장치의 제조는 종종 평활 평판면, 어떤 중간 란에서 또는 처리되는 웨이퍼면 중 하나, 즉, 상관층의 면을 요구한다. 본 발명에서의 검출은 전도성 기판상의 유전체 층의 두께를 용량적으로 측정하는 것에 의해 달성된다. 상기 측정은 유전체 층, 플랫 전극 구조 및 상기 물품 및 전극 구조와 인터페이싱되는 액체를 포함한다. 폴리싱 슬러리는 인터페이싱 액체로서 동작한다. 상기 전극 구조는 측정 전극, 상기 측정 전극을 둘러싸는 절연기 가아드 전극 및 상기 가아드 전극을 둘러싸는 다른 절연기를 포함한다. 측정시 구동 전압은 측정 전극에 인가되며 주변 가아드 전극에 대한 부트스트랩 장치에서, 그것에 의해 션트 누설 저항으로부터 인터피어링 효과 없이 유전체 층의 캐패시턴스를 측정한다. 상기 처리 및 장치는 평판화 폴리싱동안 원위치의 전도성 기판상의 유전체 층 두께 측정 뿐만 아니라, 다른 처리에서 기판상의 유전체 층 두께 측정에 사용되며, 에칭 처리후 또는 종래 유전체 층 두께를 측정한다.
