Abstract: The radius of curvature of the outer surface of a panel is 10,000 mm or more, and a shadow mask is made of a material containing 95% or more of iron. A sagging amount change curve along a curve C1 on the surface of the shadow mask, which a plane passing through a center P0 of a useful area of the shadow mask and parallel to a tube axis and a major axis crosses, satisfies a particular Condition 1. Assuming that an intersection between the curve C1 and a useful area end of the shadow mask is a major axis end PL, a distance from the center P0 to the major axis end PL along a major axis is W, and a point on the curve C1 away from the center P0 by ?×W in the major axis direction is P1, a sagging amount change curve along a curve C2 on the surface of the shadow mask, which a plane passing through the point P1 and parallel to the tube axis and the minor axis crosses, satisfies a particular Condition 2.

Abstract: A panel (2) of a vacuum envelope includes a substantially rectangular effective portion (8) having a substantially flat outer surface and also having a phosphor screen 1 formed on an inner surface, and a skirt portion (9) provided along a peripheral part of the effective portion and extended substantially perpendicularly to the effective portion. A funnel (3) is bonded to the skirt portion. A reinforcing band for fastening the skirt portion is attached round an outer surface of the skirt portion. When a distance in a direction of the tube axis from a bonding part between the panel and the funnel to an end of the reinforcing band on the outer surface side of the effective portion is represented by a and a distance in the direction of the tube axis from the bonding part to a central position of the outer surface of the effective portion is represented by h, the reinforcing band is arranged to satisfy a ?0.9h.

Abstract: The mask body satisfies the following conditions, (ZMD?ZMH)/LMS?0.020, and 0.065?ZMD/LMD?0.095 where in a substantially rectangular effective region with a predetermined curvature of the mask body, LMD is a distance between a central part and a diagonal-axis end of the effective region, LMS is a distance between a horizontal-axis end and the diagonal-axis end of the effective region, ZMD is a height difference between the central part and the diagonal-axis end in a direction of the tube axis, and ZMH is a height difference between the central part and the horizontal-axis end in the direction of the tube axis. With this structure, the mechanical strength of the mask body can be improved, and deformation of the mask body in a fabrication process and due to external shock can be prevented.

Abstract: The disclosed invention relates to a foil type fluid bearing including a foil assembly. The foil assembly supports a journal within a stationary retaining member and includes a top foil that is disposed on the inside in the radial direction, three mid foil layers that are disposed outside the top foil, and corrugated bump foils disposed outside the mid foil layers. When the journal is radially displaced, a large frictional damping force is generated between the three mid foil layers, thereby enhancing the function of supporting the journal. Moreover, layering the three mid foil layers can increase the rigidity against a load in the radial direction, thus preventing the top foil from deforming in a wavelike manner and thereby allowing the function of the foil type fluid bearing to be reliably exhibited.

Abstract: Activated lymphocytes derived from cord blood are excellently effective for preventing and treating various types of tumors and various types of infection. With interleukin 2 and/or anti-CD3 antibody, the lymphocytes derived from the cord blood is prepared by segregating lymphocytes from the cord blood and proliferating the segregated lymphocytes directly in vitro or segregating monocytes from cord blood and proliferating the monocytes in vitro. Also, the cord blood-derived activated lymphocytes can be effectively used for preventing recurrence of the diseases and promoting the take of stem cells or other organs.

Abstract: According to the present invention, HLA matching donor-originating activated lymphocytes highly effective in the treatment of patients with tumors, viral infections and autoimmune diseases are prepared by collecting cells contained in peripheral blood originating from an HLA matching donor or peripheral blood originating from an HLA matching donor achieving micro-chimerism and by stimulating and propagating the cells thus collected with, for instance, interleukin 2 and anti-CD3 antibodies or the like. The HLA matching donor-originating activated lymphocytes thus prepared can be administered to an HLA matching patient with a tumor, a viral infection or an autoimmune disease for therapeutic or preventive purposes.

Abstract: The outer surface of a panel effective section of a vacuum envelope is substantially flattened. A phosphor screen is formed on the inner surface of the effective section and includes stripe-shaped phosphor layers and light absorption layers arranged in parallel. The panel effective section is formed such that a corner portion is 8 mm to 15 mm thicker than the central portion and the transmittance of the central portion is set at 40% to 60%. The phosphor screen is formed such that the ratio of the width of a light absorption layer to the pitch of phosphor layers in the central portion of the panel effective section is larger than or equal to that in the peripheral portion thereof. A shadow mask is opposed to the phosphor screen and has a mask body in which a number of electron beam passage apertures are formed. The pitch of apertures formed in the peripheral portion of the mask body is 1.3 to 1.4 times as large as that of apertures formed in the central portion thereof.

Abstract: In a color cathode ray tube in which the external surface of an effective portion of a panel has a flat surface or a slight curvature, the shadow mask is set such that the layout distance between electron beam through hole array near the long side of an effective surface of the shadow mask is larger in the vicinity of the short axis than the layout distance at the center of the effective surface. Further, the layout distance becomes gradually smaller in direction away from the short axis, and thereafter, the layout distance changes to an increase. In the vicinity of the short side of the effective surface, the layout distance becomes equal to or larger than the layout distance near the short axis. Therefore, the curvature of the shadow mask and the electron beam through hole array are set in proper condition, and mislanding of beam landing due to deformation or oscillation of the shadow mask can be reduced. At the same time, howling of the phosphor screen can be minimized.

Abstract: The thickness of a face panel is greater at a peripheral edge portion than at a center portion. At the inner surface of the face panel, a curvature radius in a short axis direction on a long axis is set to decrease from the center of the face panel toward a long axis end and, with L representing a distance from the center of the face panel to the long axis end, has a minimal value at a position spaced from the center of the face panel more toward the long axis end than L/2. A phosphor screen on the face panel has phosphor layers and non-emitting black layers and a percentage of the non-emitting black layers per unit area at least in the neighborhood of a diagonal axis end of the face panel is equal to or smaller than that at the center portion of the face panel.

The effective surface and the non-aperture portion of the mask main body are formed in a curved surface having a radius of curvature in the short axis direction.
