    摘要: A nuclear fuel element comprises plutonium-containing fuel pellets filled in a cladding with both end sealed with end plugs. One end plug has a filter at the inside and a passage communicating with the space in the cladding through the filter. The passage is sealed at the surface part of the end plug by welding. The filter and the passage in the end plug are utilized for withdrawing a gas in the cladding filled with the fuel pellets in a process for fabricating the nuclear fuel element. The filter traps nuclear fissionable materials in the cladding to prevent its leakage to the outside. After the withdrawal of the gas, a helium gas is filled in the cladding through the passage in the end plug. After completion of these operations, the passage in the end plug is sealed as mentioned above.

    摘要: A method of manufacturing a cup-shaped coil assembly is described which employs a coil bobbin of a special design. The bobbin comprises a cylindrical member, a disc connected with one end of the cylindrical member to close it, a cap member detachably fitted into an opening in the other end of the cylindrical member, and a shaft disposed in alignment with the axis of the cylindrical member and having its one end attached to the disc and its other end slidably extending through the cap member. The method comprises the steps of assembling a coil bobbin in the manner mentioned above, and forming a coil around the bobbin by a skewed winding of wire, pressing the cap member into the cylindrical member, diametrically enlarging an opening formed at one end of the coil, and removing the cap member from the coil formed.

    摘要: An uneven surface portion is formed on the inner surface of a lamp holder to thereby reduce the contact area between the inner surface of the lamp holder and a light incident face of a light guide plate. The light incident face of the light guide plate and the inner surface of the lamp holder are prevented from coming into close contact with each other due to heat transferring from cold-cathode fluorescent tubes and to the light guide plate. The heat transferring via the lamp holder to the light guide plate is intercepted by an air layer occurring between the uneven surface portion of the lamp holder and the light incident face of the light guide plate. Accordingly, it can be prevented that a part of the lamp holder sticks to the light incident face of the light guide plate of the backlight when the lamp holder is replaced.
