Title: Image distortion correction system
Inventor: HAGIO KENICHI
IPC: H04N7/18
Filed: 1991-12-24
Abstract: PURPOSE:To prevent picture elements from being deteriorated even when a wide angle lens is used by correcting image distortion by address conversion and finding out the value of a picture element on a converted address by interpolating calculation between adjacent picture elements. CONSTITUTION:An input image signal is digitized by an A/D conversion means 1 and a picture address is formed by an address forming means 4 based upon a synchronizing signal separated by a synchronizing signal separating means 3. The picture address is converted by an address converting means 5 to correct image distortion. Then the value of a picture element is interpolated by an interpolating operation means 3 based upon the converted picture address. The interpolated picture element value is stored in an image memory 8 and converted into an analog signal by a D/A conversion means 9 and the analog signal is mixed with the synchronizing signal by a synchronizing signal mixing means 10. Consequently the image distortion included in the input image signal is corrected and an output image signal with high picture quality can be obtained.

Title: Catalytic composition for isomerizing dichlorotoluene and its isomerization method
Inventor: KATO HAJIME
IPC: B01J29/26
Filed: 1998-12-04
Abstract: PROBLEM TO BE SOLVED: To improve a catalytic activity of a dichlorotoluene isomerizing reaction by a method wherein a secondary particle size of a mordenite in a catalytic molded product is specified. SOLUTION: A catalytic activity of a DCT isomerizing reaction is improved by specifying a secondary particle size of a mordenite in a catalitic molded product in the catalytic composition of DC(dichlorotoluene) at 5 μm or under. The catalytic composition containing the mordenite is necessarily made an acidic type prior to being used for the DCT isomerizing reaction. In order to allow such catalyst to function more effectively, it is preferable that rhenium having a hydrogenating active capability is supported by the catalyst, or a silver ion is introduced into the mordenite. Further, fluorine and/or phosphorus constituents are preferably added thereto. Furthermore, when used for the reaction, the DCT being a raw material is preferably brought in contact with the catalyst in a liquid phase. Allowing hydrogen to coexist as a supply raw material is preferable on restraining a decrease of the catalytic activity.
