Title: Image processing unit
Inventor: MURATA KAZUYUKI
IPC: H04N1/387
Filed: 1995-02-06
Abstract: PURPOSE: To use a page memory efficiently by shifting a coordinate to be stored in the page memory into the page memory so as to map the data when read image data are mapped to the outside of a range of the page memory. CONSTITUTION: When an integer coordinates (Xint, Yint) are outside a range of an image memory an X coordinate transforming circuit 541 and a Y coordinate transforming circuit 542 shift the coordinates to be in the range to provide an output of the coordinates (Xint, Yint). The read image data at the outside of the image memory are shifted in the image memory area and stored therein through the shift processing as above. When image data stored in the image memory are read, the data are read by reflecting the coordinate by assuming shifted origin coordinates O (Xsmin, Ysmin) to be shifted as a coordinate origin of the image memory. The origin coordinates O (Xsmin, Ysmin) are stored in the register automatically when the reading of the image is finished.

Filed: 1987-01-28
Abstract: PURPOSE:To accurately detect whether or not contents are affected by bringing an ultrasonic probe into contact with one external surface of a package body which contains the contents and sending an ultrasonic wave, and deciding a detected value. CONSTITUTION:The clamping interval of the package body is made constant, and the ultrasonic probe which contacts one external surface of the package body sends an ultrasonic wave of certain frequency and also receives a reflected wave which is reflected by the other surface of the package body or a reflecting plate provided outside the surface. Here, if the contents are affected, the specific gravity or viscosity varies, so the affected contents and unaffected contents differ in the scattering, diffu sion, and absorption of the ultrasonic wave, so that the detected value of the difference in acoustic speed between a sent wave and a received wave, the acoustic wave of the received wave, the time from the transmission to the reception, or the attenuation speed of ultrasonic wave energy is different. For the purpose, several frequencies are selected as the frequency of the ultrasonic wave to be sent and the best frequency and detection items to be detected are found according to the purpose of he inspection of this package body, thereby accurately deciding whether or not the contents are affected.

Title: Detoxifying method of gaseous nitrogen trifluoride
Inventor: JINBO TAKASHI
IPC: B01D53/86
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To safely and efficiently treat NF3 by allowing a gas containing the NF3 and ammonia to contact with a catalyst and subjecting at least a part of a product to an adsorptive removal or an absorptive removal by solvent. SOLUTION: After mixing a gas containing the NF3 such as waste gas from a super LSI etching device, waste gas of a CVD clanging gas and leakage gas from a NF3 vessel with the ammonia, the mixture is introduced to a reactor provided with a catalyst such as metal, oxide, carbonate, sulfate and fluoride of Na, K, Cs, Mg, Ca, Sr, Ba, Al and Ga and decomposed. The NF3 is previously diluted with the gas such as nitrogen preferably since a large exothermic reaction is caused when the NF3 is brought into contact with the catalyst. Since hydrogen fluoride is formed as a result of a catalytic reaction with the catalyst, the hydrogen fluoride is adsorbed and removed with a basic oxide such as alkaline earth oxide and soda lime or washed and removed with alkali aq. soln. In such a way, the NF3 is completely and economically removed.
