Abstract: The invention relates to an intervertebrae implant comprising two side walls (1, 2) arranged at a distance to each other, a front wall (3) connecting the same at their one end, a back wall (4) connecting the same at their opposite other end, and one opening each on the base and cover part extending at right angles to the afore-mentioned walls. The invention also comprises at least one element (60, 61) provided for in the space (5) enclosed by the above walls, which element has a surface pointing towards the base or cover part and can be moved back and forth between a first final position in which said surface projects at least partly outwards beyond the base or cover part and a second final position in which the surface does not project beyond the base or cover part.

Abstract: A method of manufacturing electrophotographic toner according to the present invention includes the step of mixing at least toner particles and an additive for a predetermined mixing time to produce the toner, with the predetermined mixing time being set within a range from a first mixing time, at which chargeability of the toner (which changes according to the duration of mixing of the toner particles and the additive) shows a singular point, through a second mixing time, at which preservation of the toner (which also changes according to the duration of mixing) shows a singular point. By this method, a mixing time which maximizes the effects of the additive can be easily set. Accordingly, using a method simpler than conventional methods, a toner can be obtained which has good characteristics with regard to both chargeability and preservation.

Abstract: A reflective type liquid crystal display device in accordance with the present invention includes a reflector film having excellent polarization preservation properties and an anisotropic diffusing film for diffusing only the light polarized in a particular direction. The anisotropic diffusing film is composed of a complex of liquid crystal and a polymer and selectively diffuses incident light. If a liquid crystal layer composed of dichroic dye and liquid crystal is employed, it becomes possible to carry out high contrast display with the anisotropic diffusing film and the reflector film and to prevent reflections of nearby objects appearing on the screen.

Abstract: A magneto-optical disk 1 has a track, wherein one of the sidewalls (sidewall 4) of a groove 2 is wobbled by a wobble signal, and is provided with a notch 5 in the track having a different frequency from the wobble signal. The absolute position of the magneto-optical disk 1 is detected with a sample bit stored by the notch 5 of the track, and an information bit is stored with a recording/reproducing clock synchronizing with that position. By forming the notch 5 in this manner, information can always be recorded at the same information bit position, regardless of how many times information is rewritten. Therefore, a gap area and a buffer area, which have conventionally been essential, are not needed on the optical disk. Consequently, it is possible to use a recording area effectively.

Also disclosed are radiopharmaceutical kits for preparing the labeled radiopharmaceutical compounds.

Abstract: An image-forming system is constituted by connecting a plurality of digital copying machines to a communication apparatus so that the digital copying machines can transmit and receive image information with each other. As an instruction for image processing is inputted at any of the digital copying machines, a control section of the digital copying machine outputs the image information to a digital copying machine that is capable of carrying out the image processing. The digital copying machine that is assigned the image processing carries out a predetermined image processing on the image information and returns the processed image information via the communication apparatus. The image information is then visualized by a digital copying machine that receives the image information.

Abstract: In a method of video image motion compensation a plurality of motion vectors are derived by techniques such as phase correlation between pairs of images. In order to produce a set of motion vectors which can be used to define substantially all the motions in an input image, sets of vectors are derived from comparisons with preceding and succeeding images and are then combined to produce a set of vectors for assignment to an input image. Once the set of vectors has been derived they are assigned to the input image from where they can be projected to produce a desired output image. The vectors are assigned to individual elemental areas of the image and certain elemental areas have two (or more) vectors assigned to them.

Abstract: A process for preparing a toner includes forming a melt-kneaded mixture by mixing a raw material mixture containing a quaternary ammonium salt compound at a temperature ranging from (M-7).degree. C. to (M+7).degree. C., where M is a melting point of the quaternary ammonium salt compound, with a kneading device having a discharge port whose temperature is set lower than a temperature at which a melt viscosity of the melt-kneaded mixture at the discharge port is not higher than 10,000 Pa.a, removing the melt-kneaded mixture from the kneading device, rolling out the melt-kneaded mixture to a thickness ranging from 1.2 mm to 3.0 mm, and cooling down the melt-kneaded mixture. With the use of the toner produced by this process, the amount of charge during copying is retained in an appropriate range irrespectively of the working atmosphere and conditions of use, thereby maintaining a good image density.
