Abstract: A shock absorbing structure formed by including a column member, a ring member that is provided by being fitted onto the column member and has elasticity, a first pressure receiving portion that is connected to an upper end of the column member, and a second pressure receiving portion that is connected to a lower end of the column member, wherein the column member tilts with respect to at least one of the first and second pressure receiving portions with pressure reception, and is restored with decompression, and the ring member is caused to undergo bulging deformation to an outer circumferential side direction from an inner circumferential side by tilting of the column member.

Abstract: A structure including hard bone portion extending to a sole side face outer side at a time of pressure reception, and elastic soft skin portion provided at an outer side of the hard bone portion, absorbs impact at a time of landing and the like, where at least part of the hard bone portion is along sole side face, and the elastic soft skin portion have a structure wherein at a time of pressure reception, the hard bone portion undergoes bending deformation in a vertical section to extend to the sole lateral side, and by receiving the deformation, the elastic soft skin portion undergoes elastic deformation to bulge to the sole lateral side to absorb a received pressure load, thereafter, with decompression, the elastic soft skin portion undergoes elastic deformation to contract to the sole inner side, and with this, the hard bone portion is restored to an initial state.

Abstract: Provided is a color cathode-ray tube with a magnetic shield member which is capable of efficiently reducing only the amount of mislanding caused by the external magnetic field applied in one direction by effectively utilizing the shape effect of a magnetic substance and which can be readily designed. A U-shaped magnetic substance is formed by curving an elongated magnetic substance into a U-like shape. One end of the U-shaped magnetic substance is fixed to a long side wall side of a frame, while the other end thereof extends toward an electron gun. The U-shaped magnetic substance is magnetized therealong due to the shape effect thereof, concentrating an induction field on the area surrounded by the U-shaped magnetic substance. Thus, a great shield effect can be obtained. Further, the U-shaped magnetic substance is readily magnetized in a special direction due to its shape anisotropy.

Abstract: In a color cathode-ray tube having a shadow mask disposed to face a phosphor screen and having apertures for passage of an electron beam, and a frame for reinforcing tile periphery of the shadow mask, a magnetic shield comprises strips of magnetic material each having a first end fixed to the frame and a second end disposed closer to the electron gun. Because of the elongated shape, the strips are magnetized easily only in the direction of their length. As a result, an external magnetic field parallel to the strips, and hence with the tube axis, is reduced or canceled. Moreover, if each strip is bent near its second end so that the second end is directed toward a horizontal plane containing the tube axis, an external magnetic field in the direction in which the second end is directed is enhanced. This will further reduce deviation of the electron beam path In the horizontal direction.
