Abstract: A magnetic recording medium in accordance with the present invention is constituted by a first magnetic film having a magnetic anisotropy in a first direction parallel to the film surface and a second magnetic film that is formed on the first magnetic film and that is made of an amorphous alloy film of a rare-earth metal and a transition metal having a magnetic anisotropy in a second direction that is parallel to the film surface, and different from the first direction. In the above-mentioned magnetic recording medium, the first and second magnetic films have magnetic anisotropies having directions parallel to their surfaces and different from each other. When a magnetic latent image is formed on the magnetic recording medium of this type, it is possible to reduce the height of serration in the serrate magnetization transition structure appearing in the border of magnetization inversion in the magnetic latent image.

Abstract: A magneto-optical recording medium with a reproducing layer that exhibits in-plane magnetization at room temperature and that comes to exhibit perpendicular magnetization as temperature rises. The second shielding layer is used to block the magnetization of record bits other than a record bit to be reproduced from being copied on a signal reproducing area in the reproducing layer. Consequently, even in the case of high-density record bits in the recording layer, only the magnetization of the record bit to be reproduced is copied on the reproducing layer. Therefore, the application of the magneto-optical recording medium makes it possible to produce superior reproducing signals even in the case where the records bits with high density are formed on the recording layer.

Abstract: An electrophotographic toner is made up of toner particles composed of irregularly-shaped core particles made chiefly of binder resin, and surface-modifying fine particles which are first dispersed over and attached to the surface of the core particles, and then affixed or formed into a film thereon. The BET specific surface area, based on N.sub.2 adsorption, of the toner particles is less than 0.64 times the BET specific surface area of the core particles and surface-modifying fine particles combined together. Further, this value is 1.07 times the BET specific surface area of hypothetical toner particles which are perfect spheres. Consequently, the toner is not prone to problems such as filming, toner scattering, and fogging which are caused by peeling, separation, etc. of the surface-modifying fine particles, nor to poor cleaning due to spherical toner particles.

Abstract: A video signal 21 is input to a motion-compensated median filter to produce a preliminary blemish-concealed signal 23. The preliminary signal and the original input signal are passed via appropriate delays to respective inputs of a selector switch 31 and to a side chain circuit. The selector switch is controlled by the side chain circuit output and the selector switch output 22 forms a final blemish-concealed video signal. In the side chain circuit a difference signal C is generated to indicate differences between the input signal and the preliminary signal. The difference signal C is processed in two parallel circuit branches to remove differences having gently-sloping edges and differences corresponding to similar-sized differences in similar areas of adjacent frames, which are likely to be motion artifacts.

Abstract: In an image-forming system, when the user inputs an instruction for image processing to an input section in a digital copying machine, the control section of the digital copying machine outputs image information of a document to a host computer. The host computer carries out a predetermined image process on the inputted image information, and outputs the processed image information to the digital copying machine through a transferring device. The control section of the digital copying machine supplies the processed image information to an image-recording section, and the image-recording section forms a visual image based on the image information. With this arrangement, merely by installing necessary processing functions in the host computer, it becomes possible to eliminate the need for purchasing a new digital copying machine to replace the older one with relatively outdated functions, and also to reduce the burden on users on an economic basis.

Abstract: A thermocouple probe 10 suitable for use in a gas turbine engine comprises a thermocouple element 12 which is coaxially arranged inside a protective sheath 16. The thermocouple element 12 is resiliently supported by a helical member 18 which insulates the element 12 from deleterious vibrations induced in the sheath 16. In use, the thermocouple probe 10 projects through an aperture 30 in the casing 32 of a gas chamber 34. Vibrations in the probe 10 are further reduced by ensuring that the longitudinal axis AA of the probe is angularly offset from the central axis BB of the aperture 30, such that the outer periphery of the sheath 16 is in contact with the inner periphery of the aperture 30 in two diametrically opposite and axially offset locations.
