Title: Production of isopropenylphenol polymer
Inventor: KURATA NOBUYUKI
IPC: C08F8/12
Filed: 1985-02-04
Abstract: PURPOSE:To obtain a polymer of a high MW and a narrow dispersion in an industrially advantageous manner, by hydrolyzing a polymer obtained by cation- polymerizing an ester of isopropenylphenol with the aid of antimony pentahalide as a catalyst. CONSTITUTION:An ester of isopropenylphenol is cation-polymerized with the aid of antimony pentahalide as a catalyst. The obtained polymer is hydrolyzed. The above ester is obtained by reacting isopropenylphenol with an acid chloride or an acid anhydride (desirably, acetic anhydride) in the presence of a base or an acid catalyst. The obtained ester is dissolved in a reaction solvent and an antimony tetrahalide (desirably, antimony pentachloride) is added as a polymerization catalyst to the solution to carry out cation-polymerization. The obtained polymer is dissolved in a hydrophilic organic solvent (e.g., THF) and hydrolyzed by the addition of an aqueous solution of an acid or base catalyst. The weight-average MW of the obtained polymer is about 3,000-10,000 and its dispersion is about 1.10-1.60.

Title: Wafer processing device
Inventor: TAKANO HIDEAKI
IPC: H01L21/304
Filed: 1990-01-29
Abstract: PURPOSE:To eliminate the generation of wafer contamination by making larger the area of an intake section of processing liquid than that of a discharge section and providing a leak free funnel-like carrier on its side. CONSTITUTION:A plurality of wafers 1 are housed in a carrier 2 which has no opening on its sides. With a larger-sized intake section of processing liquid placed under, the wafers are installed on a carrier receiving base 12 in a tank 6. Then, the processing liquid 11 is adapted to circulate from the lower part of the carrier 2 by way of a filter 4 by the drive of a pump 5. At that time, the processing liquid 11 does not stagnate inside the carrier 2, but flows to the upper part of the carrier 2 and returns to the tank. Since the bottom of the carrier 2 is positioned higher than the surface of the processing liquid 11, no wafers are kept off from direct contact with the processing liquid contaminated with dust or the like. As a result, dust processing liquid 11 is supplied to the wafers 1 constantly and dust generated during the processing is drained from the upper part of the carrier, which reduces the dust contamination on the surfaces of the wafers 1.

Title: Display unit
Inventor: IKEGAMI MITSURU
IPC: G06F3/14
Filed: 1978-02-24
Abstract: PURPOSE: To make a raster scan-system display high-speed by storing section information, which indicates the same luminance level section, and luminance level information, which indicates a luminance level in the same luminance level section, in a buffer memory for screen refresh.  
     CONSTITUTION: Section information indicating the same luminance level section and luminance level infomation indicating the absolute value of a luminance level in each section or the relative value to the just preceding section are received from a central processing room and are stored in a buffer memory for screen refresh. Then, section information and luminance level information are read out from buffer memory successively to generate a luminance signal for every section, and this signal is supplied to a display part to display a prescribed variable density pattern. Thus, since a fine variable density pattern can be displayed in a high speed on a basis of section information and luminance level information and the luminance level is designated for every section of the same luminance level, the capacity of the buffer memory can be reduced.
