Title: Alcohol separation method by pervaporation
Inventor: KOYAMA KIYOSHI
IPC: B01D61/36
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To enable only specific alcohol to be separated from water and other alcohols by using a transmission film for transmitting the specific alcohol faster than water and transmitting the other alcohols later than water. SOLUTION: A condenser 4 and a vacuum pump 5 are provided in order in series at a transmission side of the transmission film 3, and transmitted gas transmitted through the transmission film 3 with vacuum suction is cooled with a refrigerant C and separated into condensate and noncondensable gas. Subsequently the condensate is discharged outside the system from the condenser 4 as transmitted condensate T or recovered and the noncondensable gas is sucked to a vacuum pump 5 side and discharged from an outlet of the vacuum pump 5 as transmitted noncondensable gas G. Meanwhile, raw liquid S remaining without transmitting the transmission film 3 is discharged or recovered as non- transmission liquid L at a nontransmission side of the transmission film 3. Thus, this pervaporation is highly suitable for an alcohol separation method.

Title: Manufacture of semiconductor device
Inventor: MACHIDA AKIRA
IPC: H01L29/78
Filed: 1987-06-11
Abstract: PURPOSE:To reduce the Miller capacity between a gate electrode and source and drain regions and to decrease a capacity between the drain and the gate, by thermally oxidizing the gate electrode so that a gate oxide film is thicker at the ends thereof. CONSTITUTION:An oxide film including a side oxide film 7 covering a gate electrode 5 and an oxide film on a substrate 1 are chemically etched without any masking layer so that they are removed. The gate electrode 5 is thereby exposed totally while a gate oxide film 3 is also side etched deep from the ends of the gate electrode 5. The whole substrate 1 is reoxidized and the gate oxide film 3 is made thicker at the ends of the gate electrode 5 so as to utilize the principle of 'bird's beak' produced at the ends of a silicon nitride film during selective oxidation. Thereby, the source and drain regions 8, 9 and the gate oxide film 3 are formed thicker than the other parts and the Miller capacity is reduced. N<+>type source and drain regions 8b, 9b are formed by ion implantation with the gate electrode 5 and the reoxidized film 10 used as a mask. Accordingly, the source and drain regions 8, 9 have a DDD (Double Diffused Drain) structure, with a reduced resistance.
