摘要:
A process for catalytic reaction of heavy oils and a particulate solid medium, which comprises withdrawing a part or the whole of the used medium from the reactor, separating the withdrawn particles into the particles which have been rendered magnetic by the deposition thereon of nickel, vanadium, iron and copper originally contained in the heavy oils, and non-magnetic particles, using a high gradient magnetic separator which is so designed that a ferromagnetic matrix is placed in a uniform high magnetic field, and returning the non-magnetic particles of the medium into the reactor for re-use.

In a copying machine having an image memory that stores image data, a DRAM control IC that repetitively reads out image data from the image memory, and an image forming section that forms the images for the specified number of copies, a write processing section having a number of pixels counter that counts the number of pixels included in the image data for the predetermined number of pages at the time of reading, a first memory that stores the count value for the nth copy, a second memory that stores the count value for the (n+1)th copy, and an image control CPU that compares the count value stored in the first memory with the count value stored in the second memory and thereby judges the occurrence of errors in the print process if the two counts are not equal to each other and carries out error processing.

An image forming apparatus comprises a conveyance section which conveys at least one sheet of a second special sheet group so as to be inserted between two special sheets of a first special sheet group on a stacking section. A rest of special sheets which belong to the same set as a special sheet of the second special sheet group having been last supplied is supplied and ejected to a sheet ejection destination other than the stacking section before a special sheet of the second special sheet group is inserted after the latter sheet of the two special sheets of the first special sheet group are supplied.

There is described an image forming apparatus combined with a finisher for applying finish processing such as stapling. The image-forming apparatus includes: a reading section to read an original image so as to generate image data of the original image; a designating section to designate a first direction of the original image to be read by the reading section and a second direction of an output image to be ejected; an image-processing section to apply image-processing, which includes an image-rotation processing, to the image data so as to generate processed image data; a controlling section to control a rotation angle to be employed for rotating the image data by the image-rotation processing, referring to the first direction and the second direction, so that a direction of the output image coincides with the second direction; and an image-forming section to form the output image based on the processed image data.

The present invention relates to a supply system for pre-treating a petroleum distillation residual oil to be fed to a hydrogenation apparatus. In order to remove iron fine particles having a particle size of less than 25.mu. in the feed oil which could be not removed in the prior art, by constituting a system comprising a heater for heating the feed oil to a given temperature by heat exchange with a high temperature bottom oil of a fractionating tower after hydrogenation treatment of the feed oil, a filter equipped with a back washing mechanism for filtering solid materials in the feed oil after heating, and a high gradient magnetic separator for magnetically separating magnetic iron fine particles having a particle size of less than 25.mu. contained in the feed oil. By the use of the above bottom oil of the fractionating distillation tower as a washing oil of the high gradient magnetic separator, iron fine particles in the feed oil were able to be removed by repeating an iron removing operation and a washing operation. By the use of this supply system for pre-treating the feed oil, iron fine particles attributable to clog and deterioration of a catalyst layer of the hydrogenation apparatus can be reduced, thereby the time capable of continuous running of the conventional hydrogenation apparatus can be extended.

摘要:
A recording sheet feeding device for use in an image forming machine, in which a plurality of sheets on which a first image has been recorded are successively fed from a sheet stacker for a second image to be formed, provided with a sheet pressing mechanism above the stacker which takes a pressing or a non-pressing position with respect to sheets on the stacker. While sheets are being conveyed to the stacker, a pressing operation on the sheets is conducted by driving the mechanism at least twice. Sheet feeding from the stacker is started after the first pressing operation of the mechanism. A feeding timing of the first sheet to be fed after a second pressing operation is delayed compared with a feeding timing of other sheets. In another structure, a periodical pressing operation is conducted each time a predetermined number of sheets are conveyed into the stacker and feeding is started when a sheet preceding by a fixed number from the last sheet in a set number of sheets in the first image forming operation is conveyed into the stacker.
