Abstract: A yellow toner for full-color electrophotography is made of yellow toner particles, each toner particle containing a binder resin and C.I. Pigment Yellow 62 and/or C.I. Pigment Yellow 168 as a yellow coloring agent. The above-mentioned yellow toner is used in combination with a carrier to prepare a two-component yellow developer.

Abstract: A color toner includes a binder resin composition comprising a binder resin A with a softening point in the range of 85.degree. to 110.degree. C., and a binder resin B with a softening point in the range of 115.degree. to 135.degree. C., with the binder resin A and the binder resin B being compatible with each other; a coloring agent; and a wax with a melting point in the range of 65.degree. to 90.degree. C., which is not compatible with the binder resin composition and dispersed in the binder resin composition.

Abstract: An input/display apparatus for handwritten characters is capable of quickly inputting handwritten characters, freely editing characters inputted, and storing a lot of handwritten characters with a limited storing capacity. On a display panel provided with a display surface, the orthogonal coordinates of which are preset, a touch panel provided. An input surface of the touch panel, the orthogonal coordinates of which are preset, is disposed in such a way that the display surface and the input surface overlap each other. When the input surface is indicated with an input pen, the indicated coordinate point is outputted. At the time of handwriting input, when the input surface in the input/display area for characters is continuously indicated, coordinate points on the display surface corresponding to the plurality of indicated coordinate points are displayed.

Abstract: A schedule-managing apparatus is capable of moving or copying a schedule to another date, for example, to another month than that displayed on a display section, at the time when a starting date is stored in a storing portion. A schedule-managing apparatus includes a control device for holding schedule information, stored in a storing portion as it is, while renewing stored data information according to inputted coordinates, when a user is inputting coordinates in a calendar display region by altering the coordinates successively. It further includes a scroll indication window provided adjacent to a display screen of a display portion. Finally, another control device is included for scrolling a displayed content of the display portion when the coordinate of the scroll indication window is inputted via a coordinate input device.

Abstract: A toner for developing latent electrostatic images composed of a continuous phase containing a binder resin, and a disperse phase dispersed in the form of finely-divided disperse phases in the continuous phase, containing a resin which is not the same as the binder resin for use in the continuous phase, and finely-divided particles of a releasing agent which are dispersed in the resin, with a coloring agent being dispersed in the continuous phase and/or the disperse phase.

Abstract: An electron gun in which at least two of a plurality of electrodes constituting the electron gun are endowed with structures for generating rotationally-asymmetric electric fields, in electron-beam apertures of the electrodes or around the electron-beam apertures, and a cathode-ray tube which comprises the electron gun can enhance focus characteristics and attain favorable resolutions over the whole area of a screen and in all the current ranges of electron beams, and they do not give rise to moire in the small current range of the electron beams, without supplying a dynamic focus voltage.

Abstract: An electron gun for a color cathode ray tube having a structure that a plate electrode to be provided within the focusing electrode is given the structure adding the external portion and providing in parallel three elliptical apertures in place of providing the cutout portion at the external portion, a plate electrode to be provided within the acceleration electrode is given the structure providing the cutout portion at the external portion and the vertical axis including the center of external elliptical portion is arranged outside the center axis when the side electron beam enters the main lens is capable of correcting astigmatism and satisfying static convergence. Moreover, rotation and deformation of plate electrode during assembling of electrode can be prevented by providing the straight line portion to the side beam apertures, aberration of lens to be generated at the main lens portion can be reduced and focus characteristic can also be stablized.

Abstract: At least one of grid electrodes which serves as a main lens of an electron gun for use in a color cathode ray tube is divided into a plurality of cylindrical electrodes coaxially connected. An inner electrode is provided at the connection part between the cylindrical electrodes so that the center of an elliptical aperture of the inner electrode coincides with the center of an inner wall of the grid electrode. Thus, astigmatism in the main lens is removed, thereby improving the resolution of the color cathode ray tube.

Abstract: A television camera tube with electrostatic focusing and magnetic deflection comprises in an cylindrical envelope a beam current control, a main lens section and a sixth grid in the form of a mesh electrode. The beam current control section includes a cathode, a first grid and a second grid with an electron beam limiting diaphragm in this order. The main lens section includes third, fourth and fifth grids in the form of cylindrical electrodes disposed in this order. Around the cylindrical envelope is mounted a magnetic deflection coil whose length along the envelope axis is 0.18 to 0.40 times the distance from the beam limiting diaphragm to the mesh electrode.

Abstract: The structure of an electrode for collimation lens in an image pickup tube has an improved joint for an accelerating electrode of an electron gun and a mesh electrode. The joint has an electrode support member integral with the fore end of the accelerating electrode and having a cylindrical center portion width not overlapped with the fore end, and a glass bead for connecting the width and the mesh electrode.
