Abstract: A method of manufacturing a tubular member having a non-constant thickness by ironing at least a portion of the tubular material. The ironing apparatus can have a punch and a die, and the die can have a convex and concave side surface opposing the punch. The method can include bending an axial end portion of the tubular material to form a bent portion. The tubular material can then axially engage the die at the bent portion, and then the punch can be moved relative to the die to iron at least a portion of the tubular material.

Abstract: A method of manufacturing an organic EL element according to the present invention comprises the steps of forming pixel electrodes (801), (802), (803) on a transparent substrate' (804) and forming on the pixel electrodes by patterning luminescent layers (806), (807), (808) made of an organic compound by means of an ink-jet method.

Abstract: The invention provides an organic EL apparatus including a substrate, a pair of electrodes formed on the substrate, and a light emitting layer disposed between the electrodes is provided in order to implement a light emitting apparatus and an electronic device which decrease reflections in a display of the organic EL apparatus, and to enhance display quality. The substrate includes a transparent substrate, the pair of the electrodes is an anode disposed on the light emitting layer at the substrate side, and a cathode disposed on the light emitting layer at an opposite side of the substrate. A semi-reflection film is disposed near the anode. The semi-reflection film transmits a part of external light incident on the organic EL apparatus from the substrate, and reflects a part of the light other than the light transmitted.

Abstract: An axial force control nut assembly 10 includes a seat member 11, a fastening nut 12 rotatable relative to the seat member and a ring assembly 13 disposed between the seat member and the fastening nut. The ring assembly 13 can include one or more rings. At least one of the rings is an axial force control ring 20 is freely rotatable before a bolt axial force reaches the proper axial force and is restricted in rotation after the bolt axial force is equal to or greater than proper axial force. Alternatively or in addition, the ring assembly 13 can include an elastic deformation ring 21. A gap is defined between a radially outer portion of the elastic deformation ring 21 and the seat member 11 before the bolt axial force reaches the proper axial force. The gap between the radially outer portion of the elastic deformation ring 21 and the seat member 11 becomes zero after the bolt axial force is equal to or greater than the proper axial force.
