Title: Polishing device
Inventor: SUGAYA ISAO
IPC: B24B37/10
Filed: 2001-10-24
Granted: 2002-06-21
Abstract: The present invention can provide a solution for the problem caused by the projection of the polishing object from the periphery of the wafer by supporting the projection with a guide, and also reduce wearing between the guide and the polishing object. In polishing a wafer 2, projection of the polishing object 7 extending from periphery of the wafer 2 is supported by a guide face 5a of an annular guide 5. The guide face 5a is located at about the same plane as the polishing surface of the wafer 2. The guide 5 is mounted on the member 13 via a bearing and is coaxial with a holding portion 3 for holding the wafer 2, and is freely rotatably supported in a manner independent with the holding portion 3. The guide 5 is moveable with the projection of the polishing object 7 by the friction force with the projection of the polishing object 7. Thus, the relative speed of the projection of the polishing object 7 with the guide 5 becomes rather small, so as to reduce the wearing between the two.

Abstract: Production of 2-ethylhexyl acrylate involves esterification of acrylic acid with 2-ethylhexanol. The esterification produces a reaction mixture (B1) comprising 2-ethylhexyl acrylate, 2-ethylhexanol, acrylic acid, 2-ethylhexyl acid sulfate, traces of sulfuric acid and impurities. (B1) is washed in a column enabling separation of an organic phase from which 2-ethylhexyl acrylate is distilled off. Production of 2-ethylhexyl acrylate involves esterification of acrylic acid with 2-ethylhexanol. The esterification produces a reaction mixture (B1) comprising 2-ethylhexyl acrylate, 2-ethylhexanol, acrylic acid, 2-ethylhexyl acid sulfate, traces of sulfuric acid and impurities. The mixture (B1) is water washed in a column enabling separation of an organic phase at the head and elimination of an aqueous phase at the foot. The organic phase is directed to a heading column from which acrylic acid and 2-ethylhexanol can be recycled to the esterification reaction, and 2-ethylhexyl acrylate from the base directed to another distillation column and headed off free from heavy products. The aqueous phase is directed to a hydrolysis stage to hydrolyse the acid sulfate, the acid species resulting being neutralized with a base. The resulting aqueous phase passes to a distillation column to separate off remaining 2-ethylhexanol which is recycled to the reaction.

Abstract: A touch-control method for an LCD, including a first touch-position sensing step, a charging step, and a second touch-position sensing step. During the idling time in-between the writing periods in which each scan line turns on to write the image data into the LCD screen, the first touch-position sensing step detects the values of the liquid crystal capacitance (Ck) formed between each of the scan lines and the counter electrode panel, and detects the touch position (Y) in the scan line direction according to such values. The charging step charges a voltage signal into each of the data lines which need to be detected after the touch position (Y) in the scan line direction is detected. After the voltage signal is charged, the second touch-position sensing step detects the values of the liquid crystal capacitance (C1) formed between each of the data lines and the counter electrode panel, and detects the touch position (X) in the data line direction according to such values. Accordingly, the detected position (Y) in the scan line direction and the detected position (X) in the data line direction correspond to the location of the touch point. Furthermore, this invention also discloses an LCD with a touch-control function.

Title: CATV uplink optical transmission system
Inventor: MASUDA KOUICHI
IPC: H01B11/22
Filed: 2003-05-14
Granted: 2006-12-21
Abstract: A CATV station apparatus 100 subjects received optical signals to processes of optical-electrical conversion, signal separation, coupling, and demodulation for obtaining an uplink signal. A received photocurrent monitoring section 170 compares a received photocurrent at an optical receiving section 110 with a predetermined reference current. If the received photocurrent is equal to or higher than the reference current, an amplifying section 130 amplifies a signal output from a signal separating section 120 at a predetermined level. If the received photocurrent is lower than the reference current, on the other hand, it is determined that a non-linear phenomenon, such as stimulated Brillouin scattering, has occurred in an optical fiber 200. The amplifying section 130 then outputs a signal at a level which does not affect, even after being coupled with other signals, communications performed by other optical transmission systems.
