The apparatus includes a discriminator for discriminating whether an image having a edge and an image having high image density are to be overlaid or not; and a controller, responsive to the discriminator, for exchanging a primary coloring agent with a secondary coloring agent at a position corresponding to at least one of the edge image and a periphery of the edge image.

Abstract: In a disk cartridge of the invention, a lubricating polymer film as a resin in which a solid lubricant or a reinforcing material is dispersed is arranged in a case near the center hole of a disk. Since this lubricating polymer film is hardly abraded even with a disk whose number of revolutions per unit time is high, almost no dust is generated. Therefore, a disk cartridge with higher reliability can be provided.

Abstract: An image recording apparatus and method performs recording by making an ink adhere to a recording medium according to the blot ratio of a recording medium, when using an ink droplet or heat sensitive ink. Input recording data is discriminated based on a predetermined reference value based on the blot ratio and when the image data is larger than the reference value, the image data is reduced in order to reduce the ink dot size. Reducing the ink dot size at a recording boundary improves the quality of the image recorded at the recording boundary.

Abstract: According to a method and apparatus for processing a color image, three primary color signals are input, and the input three primary color signals are processed to obtain three color reproduction signals and a black reproduction signal. In order to obtain the black reproduction signal, a value corresponding to a minimum value of the three primary color signals is obtained, and the value is transformed by a continuous function having a downwardly convex shape, thereby defining a transformed value as the black reproduction signal.

Abstract: In a disk cartridge of the invention, a lubricating polymer film as a resin in which a solid lubricant or a reinforcing material is dispersed is arranged in a case near the center hole of a disk. Since this lubricating polymer film is hardly abraded even with a disk whose number of revolutions per unit time is high, almost no dust is generated. Therefore, a disk cartridge with higher reliability can be provided.

Abstract: A color image recording apparatus such as an ink jet printer forms color image by depositing a plurality of colored inks on a recording medium in a predetermined order. The apparatus includes a device, such as an image reader or a memory, for inputting a plurality of first color component signals that correspond to the plurality of colored inks. The first color component signals are color masked to generate second color component signals to be used for recording, at least one of the second color component signals being corrected in accordance with the predetermined order of recording.

Abstract: A coal gasification apparatus using coal powder supplies coal powder, along with oxygen or air and steam, into a reaction chamber, supplies the char produced in the reaction chamber or the char and coal, along with oxygen or air and steam into a combustion chamber formed in the lower part of the reaction chamber and burns the same in the combustion chamber to maintain the temperature therein at about 1,600.degree. C., and forms the temperature region of the reaction chamber into an agglomerated bed of fluidized coal having a temperature between 900.degree. and 1,300.degree. C.

Abstract: An image recording apparatus includes an input circuit for inputting an image signal; a correction circuit for correcting the inputted image signal; an image forming circuit for forming an image in accordance with the image signal corrected by the correction circuit; a switch for generating a signal indicating a method of observing the image formed by the image forming circuit; and a control circuit for controlling the correction circuit in accordance with the signal generated by the signal generating switch.

Abstract: An image reading and recording apparatus comprises a reader for reading an image of a document by scanning a document and a recorder for effecting recording of the image read by the reader on a recording medium by scanning one side of the recording medium. A driving and controlling device drives and controls the reader and the recorder in such a manner that the image recorded on one side of the recording medium by means of the recorder will be inverted with respect to the image of the document.

Abstract: According to a method and apparatus for detecting a kind of a recording sheet, a light source for emitting a beam on the recording sheet and a photosensitive element for detecting an amount of beam are used. The photosensitive elements located at predetermined positions are caused to detect amounts of beams reflected by upper and lower surfaces of the recording sheet. The kind of upper or lower surface of the recording sheet is discriminated on the basis of a difference between the amounts of beams reflected by the upper and lower surfaces or one of the amounts of beams.
