Abstract: A method and apparatus for the thermal treatment of heavy fuel oil. Hot vacuum residue (19) from a vacuum distillation unit (18) is fed directly to burners (36) to raise stream to generate electricity in a generator (39). A gas oil stream (20) is withdrawn from the distillation unit and subjected to mild thermal cracking conditions in a heater (24) which cracks a portion of the waxes which tend to concentrate in the heavier gas oil fractions. The heated stream is mixed with the feedstock inlet stream (16) and so serves to provide the heat energy necessary to operate the distillation unit.

Title: Automatic translating device containing control function for bilingual sentence generation
Inventor: YODA TORU
IPC: G06F17/28
Filed: 1987-08-28
Abstract: PURPOSE:To automatically identify only an updated original sentence for translation by applying the generation control to both original sentences and their translated sentences for each sentence. CONSTITUTION:The generation number of an original sentence to be translated is larger than the generation number of the corresponding translated sentence. In such a case, an original sentence input processing means 3 adds '1', for example, to each original sentence supplied from an input/output device 1 as an initialized original sentence generation number and stores these original sentences in a storing area 2a. While a translated sentence generation number '0', for example, is set at a translated sentence storing area 2b. When the translation is instructed under such conditions, a translation processing means 6 translates all original sentences owing to the fact that the generation number '1' is given to each sentence of the area 2a together with the generation number '0' given to each of corresponding translated sentences. Then the obtained translated sentences are stored in the area 2b with the generation number set at '1'. Hereafter some of the original sentences is updated with operation of the device 1 and the generation number of this updated sentence is changed to '2'. Thus only the original sentence having the generation number '2' is translated with an instruction given for translation.

Abstract: PURPOSE:To prevent contamination of the surface of a semiconductor substrate due to removal of a resist pattern and deterioration of the quality of the surface of an oxide film by providing an antioxidative film on the oxide film. CONSTITUTION:An antioxidative film 103 is provided on an oxide film 102, and a resist pattern is formed on the film. With the pattern as a mask the film 103 is removed, and then the pattern becoming unnecessary is removed. Thereafter, with the film 103 as a mask the film 102 is removed, and a spontaneous oxide film on the surface of a semiconductor substrate of an opening 107 of the film 102 is removed while the films 103 remains as it is. Thus, since the film 102 is not opened while the pattern is removed, the contamination of the surface of the substrate 101 can be prevented. Since the film 103 exists on the surface of the film 102 when the spontaneous oxide film of the substrate 101 is removed, the deterioration of the quality of the oxide 102 can be prevented.

Even when the pipe diameter D is large, besides, it is unnecessary to enlarge the thickness of the main body parts 11 and 12 so mush in accordance with this pipe diameter D. Therefore, coils 13 and 14 may be formed in the shape of a cylinder and thus manufacture can be facilitat ed.
