  • Patent number: 9689067
    Abstract: Provided is a method by which a low-oxygen and high-density molybdenum target can be efficiently obtained, while fully utilizing the characteristics of each molybdenum (Mo) starting material powder. The present invention provides a method for producing a molybdenum target, wherein a mixed powder that is obtained by mixing a molybdenum powder A, which is prepared by reducing molybdenum oxide and then crushing the resulting so as to have an average particle diameter of 2-15 ?m, and a molybdenum powder B, which is prepared by crushing a molybdenum bulk starting material having a density of not less than 6.64×10 (kg/m3) so as to have an average particle diameter of 50-2,000 ?m, is sintered under pressure.

  • Patent number: 8240448
    Abstract: According to an operation of a shift lever to parking range, a cam member at a parking rod comes in between a parking pole and a support member, and the parking pole swings so that a pawl portion of the parking rod can engage with a parking gear. A concave holding portion to hold the support member is formed at a transmission case. The support member comprises a first cylindrical outer face having a first radius R1 which is supported in a concave inner face the concave holding portion to rotate in a specified range and a second cylindrical outer face (cam-contact portion) having a second radius R2 which contacts a cam member. The first radius R1 has a center which is located at the same position as that of the second radius R2. Herein, R2 is shorter than R1.
