    摘要： An object of the present invention is to provide a material for a sliding contact whose alloy composition does not contain an environmentally detrimental substance such as Cd, which exhibits excellent contact resistance, whose electrical functions are good and free of time-course variation, and which further exhibits excellent wear resistance. The material for a sliding contact assumes the form of an Ag—Zn—Pd, Ag—Zn—Pd—Cu, Ag—Zn—Pd—Ni, or Ag—Zn—Pd—Cu—Ni alloy. In the compositions of these alloys, the Zn content is 0.1-3.0% by weight, the Pd content is 0.1-1.5% by weight, and the balance is Ag. When Cu is contained, the Cu content is 0.1-3.0% by weight. When Ni is contained, the Ni content is 0.01-0.5% by weight. Zn, Pd, and Cu are present in the Ag &agr; phase in the form of solid solution. Ni particles are finely dispersed in the alloys. A composite clad material is formed through use of the material for a sliding contact. A commutator manufactured through use of the composite clad material is incorporated into a small-sized direct current motor used in a household electrical appliance.

    摘要： An objective lens driving apparatus includes an objective lens (13) collecting a light flux emitted from a light source on a optical disk (11), and a lens holder (14) holding the objective lens (13). The lens holder (14) includes a first bonding portion (14i) and a second bonding portion (14j) for holding the objective lens (13) by means of bonding. The objective lens (13) is fixed to the lens holder (14) by applying a first bonding adhesive (25) to the first bonding portion (14i) to thereby bond the objective lens (13) thereto, adjusting an inclination of an optical axis of the objective lens (13) while causing the first bonding adhesive (25) to deform, and applying a second bonding adhesive (26) to the second bonding portion (14j). The second bonding adhesive (26) has a larger Young's modulus after curing than the first bonding adhesive (25).
