Abstract: Behind an electronic circuit, a backing member is provided. The backing member is composed of an auxiliary backing having a first thermal anisotropic property, and a main backing having a second thermal anisotropic property different from the first thermal anisotropic property. The auxiliary backing exhibits a heat diffusion effect in an X direction. The main backing exhibits a heat transfer effect in a Y direction.

Abstract: Behind an electronic circuit, an auxiliary backing having a first thermal anisotropic property is provided. A main backing having a second thermal anisotropic property different from the first thermal anisotropic property is provided behind the auxiliary backing. In the main backing, each of two outer surfaces perpendicular to a Y direction functions as a heat output surface. Heat is transferred from these two outer surfaces to a shell, which is a heat absorbing member.

Abstract: Behind an electronic circuit, a thermally anisotropic main backing is provided. The main backing has two outer surfaces (low thermal conductivity surfaces) perpendicular to an X direction. In a first gap located adjacent to one of the outer surfaces, an FPC and a first group of electric components are arranged. In a second gap located adjacent to the other one of the outer surfaces, the FPC and a second group of electric components are arranged.

Abstract: Behind an electronic circuit, a main backing is provided. The main backing has two outer surfaces (high thermal conductivity surfaces) perpendicular to a Y direction, and two outer surfaces (low thermal conductivity surfaces) perpendicular to an X direction. The two outer surfaces perpendicular to the Y direction are joined to a shell head, which is a heat absorbing member. A temperature sensor is provided on a specific one of the outer surfaces perpendicular to the Y direction. The shell head has a recess in which the temperature sensor is received.

Abstract: A graphite-coated tube, especially a cladding for nuclear fuel pellets, comprising a matrix tube of zircalloy, an oxide layer of not more than about 5,000 .ANG. laid on an inside surface of the matrix tube, and a graphite layer of at least 5 .mu.m laid on the oxide layer has a good resistance to peeling of the graphite layer.

Abstract: A flyer-type winding machine includes a forming apparatus which is linearly reciprocated with respect to an axis of a bobbin, coil form or core on which a filament is to be wound while the filament is paid out from a flyer which rotates or orbits thereabout. The forming apparatus guides the filament to the bobbin, coil form or core. Moveable pins are synchronized with orbiting of the flyer to cooperate with the forming apparatus in intermittently catching and releasing the filament so as to control the positions at which portions of each turn of the filament are laid down on the bobbin, coil form or core.

Abstract: A method and apparatus for forming a coreless armature winding for an electric machine, such as a motor, having two or more poles. A source of wire is revolved in a fixed orbit about a rotatable cylinder, the axis of this orbit being inclined with respect to the longitudinal axis of the cylinder. The wire is guided about first and second guide members positioned at opposite spaced apart locations on the surface of the cylinder. These guide members define the opposite ends of the coreless armature winding such that when the wire is wound thereabout, one complete turn is formed on the surface of the cylinder. The cylinder is rotated about its longitudinal axis in synchronism with the revolution of the wire, the cylinder being rotated by a predetermined angle corresponding to the pitch of the winding so that, as the wire continues to revolve, successive skewed turns are formed on the surface of the cylinder.
