    摘要： A PDA as an apparatus actuated by key operations comprises: a substrate; an exothermic semiconductor device provided on a first major surface of the substrate; a plurality of switches provided on a second major surface of the substrate; a key mat located on the side of the second major surface of the substrate; a plurality of pressure conveying portions protruding from one of the major surfaces of the key mat toward each of the plurality of switches, the one of the major surfaces facing the second major surface of the substrate; and a key that is provided on the other major surface of the key mat and that can be pressed down to the key mat. A contact face between the particular switch located within a certain range of the distance from the semiconductor device, and the pressure conveying portion corresponding to the particular switch, has a smaller area as compared to that of a contact face between the non-particular switch, which is a switch other than the particular switch, and the pressure conveying portion corresponding to the non-particular switch.

    摘要： The invention provides a hydrogen absorbing alloy electrode obtained by the step P1 of preparing a hydrogen absorbing alloy powder containing cobalt and nickel, the step P2 of subjecting the surfaces of the alloy particles to a reduction treatment with high-temperature hydrogen by holding the powder in a high-temperature hydrogen atmosphere under the conditions of temperature, pressure and time sufficient to reduce oxides formed in a surface layer portion of each of the alloy particles, not melting the alloy particles and not permitting the alloy particles to absorb hydrogen, the step P3 of treating the resulting powder with an acid or alkali by immersing the powder in an acid or alkaline aqueous solution, followed by suction filtration, washing with water and drying, and the step P4 of applying the resulting power to an electrically conductive substrate and shaping the substrate in the form of the electrode. The electrode thus provided has higher activity than conventionally.

    摘要： A method of producing a hydrogen storage alloy, for use in alkaline storage batteries, includes two steps. A first step involves preparing alloy particles having a CaCu5-type crystal structure and the compositional formula MmNixCoyMnzM1−z, wherein M represents at least one element selected from the group consisting of aluminum (Al) and copper (Cu), 3.0≦x≦5.2, 0≦y≦1.2, 0.1≦z≦0.9, and 4.4≦x+y+z≦5.4. A second step involves immersing the alloy particles in an acid treating solution containing a cobalt compound and a copper compound, each in the amount of 0.1 to 5.0% by weight based on the weight of the alloy particles, and an organic additive to remove oxide films from and to reductively deposit cobalt and copper on a surface of each alloy particle to form a surface region surrounding a bulk region and having a graded composition. When the sum in percentage of numbers of cobalt (Co) atoms and copper (Cu) atoms present in the surface region is given by a and that in the bulk region by b, the relationship a/b≧1.3 is satisfied.
