Title: Production of high-purity terephthalic acid
Inventor: OTA TAZUO
IPC: B01J31/04
Filed: 1990-10-03
Abstract: PURPOSE:To produce high-purity terephthalic acid by oxidizing p-xylene in the liquid phase in the presence of acetic acid solvent, carrying out hydrogenating treatment using hydrous acetic acid as a solvent, providing crystallized high-purity teretphtalic acid, refiltering the separated mother liquor and recycling the mother liquor for use. CONSTITUTION:p-Xylene is oxidized in the liquid phase with O2 in the presence of a catalyst containing Co and Mn in acetic acid solvent to provide crude terephthalic acid, which is then catalytically treated with a group VIII noble metal in the presence of hydrogen using acetic acid containing 1-50wt.% water as a solvent. The resultant reaction solution is cooled to deposit and separate crystals of the terephthalic acid. Thereby, the high-purity terephthalic acid is separated. On the other hand, the separated mother liquor is refiltered to recycle the obtained mother liquor for use as a solvent for the liquid-phase oxidative reaction. As a result, the objective terephthalic acid of excellent color quality is obtained. Since the mother liquor is recycled, yield is improved. The amount of waste water is also extremely reduced substantially without requiring waste water treating equipment.

Title: Thin film transistor
Inventor: YAMADA SOU
IPC: H01L21/336
Filed: 1994-10-04
Abstract: PURPOSE: To reduce the leak current (OFF-current) which flows when a thin film transistor is in the ON-state. CONSTITUTION: In both side parts of a polycrystalline silicon film formed on an insulating substrate 1, an N-type source region 3 and an N-type drain region 4 in which, e.g. high concentration phosphorus is introduced are formed, and the intermediate part of the regions 3, 4 is made a channel region 2. Between the channel region 2 and the source region 3, a P-type low impurity concentration region 5 in which impurities like boron are introduced is formed. When a thin film transistor is in the OFF-state, the low impurity concentration region 5 increases the potential barrier formed between the region 5 and the source region 2, even in the case of high drain voltage. Thereby the OFF-current is reduced.  An N-type low impurity concentration region 6 in which phosphorus or the like is introduced is formed between the channel region 2 and the drain region 4, and relieves the intensive electric field between the channel region 2 and the drain region 4, thereby reducing the OFF-current furthermore.
