    摘要： Disclosed is a method of predicting damage of dies for plastic processing of metals, typically, forging dies, to contribute to die design including choice of material, hardness and configuration of the die. The method is characterized in that the plastic flow criteria value “Dc” defined by the formula below is calculated: Dc=σeq/(YS×SRtotal), wherein σeq is Von Misese's equivalent stress, YS is dynamic compressive yield stress, and SRtotal is softening rate, and that the damage of die is predicted with the condition that, if the value of Dc reaches 1.0, the plastic deformation or the plastic flow begins to occur

    摘要： Disclosed is a method of predicting lives of dies for plastic processing of metals, typically, forging dies, to enable improved die design by predicting an important factor, low cycle fatigue life FL (shot number possible until the die lives end). The method is characterized in that the low cycle damage value “Dc” defined by the formula: Dc=σeq/(YS×softening rate), wherein, σeq is Von Misese's equivalent stress, YS is yield stress (including both of those at tension and compression), and that the following formula is introduced: FL=C1×exp(C2×DcC3), wherein, FL is shot number until the die fracture, and C1, C2 and C3 are constants depending on the material used, so as to presume the possible shot number of the die.

    摘要： A circularly polarized wave antenna device that has improved the orthogonality of two radiation electric fields in a degeneration-separated mode. A radiation conductor is formed on one main surface of a substrate, and a ground conductor is formed on the other main surface of the substrate opposite to the radiation conductor. A feeding conductor is formed on the side surface of the substrate so as to extend from the other main surface toward the one main surface. The radiation conductor is formed into a square shape or an electrically square shape in a plan view. On the substrate, capacitive loading conductors are provided in the extended directions of the two diagonal lines of the radiation conductor, the capacitive loading conductors being formed between the ground conductor and the radiation conductor, and having mutually different shapes between the one diagonal direction and the other diagonal direction.

    摘要： Disclosed is a method of predicting damage of dies for plastic processing of metallic materials, typically, forging dies, by predicting brittle fracture (“great crack” or “initial crack”) dominating die lives contribute to die design including choice of materials, hardness and configuration of the die. The method is characterized in that the die design is carried out by choosing the condition that none of the anticipated values of brittle fracture, Fc1 to Fc3, calculated by the formulae 1 to 3 below exceed the critical values depending on the material used. Fc1=(σm/σeq)  [formula 1] Fc2=(σm/σ1 max)  [formula 2] Fc3=(σ1max/σeq)  [formula 3] σm: mean normal stress loaded to the tensile side of the die σeq: Von Misese's equivalent stress σ1max: maximum principal stress

    摘要： A circularly polarized wave antenna which allows the matching of resonant frequencies in a higher order mode to be easily achieved. In this circularly polarized wave antenna, a flat portion is provided by flattening a portion of the peripheral side surface of a substrate. Two feeding electrodes for use in the higher order mode excitation are formed on this flat plane. On one main surface of the substrate, a circular radiation electrode is formed, while, on the other main surface of the substrate, a ground electrode is formed.
