    摘要： A pyroelectric infrared sensor includes a package having a light-receiving window, and at least two dual pyroelectric elements arranged in the package, each of the dual pyroelectric elements having first and second unit pyroelectric elements, the first and second unit pyroelectric elements being connected in series or parallel with each other so as to have opposite polarities, wherein the first and second light-receiving electrodes and the first and second back electrodes are formed such that an effective light-receiving electrode area of the first unit pyroelectric element opposing a central portion of the light-receiving window is smaller than an effective light-receiving electrode area of the second unit pyroelectric element opposing a peripheral portion of the light-receiving window. A difference between secondary infrared rays incident on the first and second unit pyroelectric elements which is caused by a difference between angles of visibility of these elements with respect to the light-receiving window can be compensated. This invention also relates to a method of manufacturing the dual pyroelectric element.

    摘要： A non-aqueous battery comprising a positive electrode material capable of being doped with and liberating lithium, a negative electrode material capable of being doped with and liberating lithium, and a polymer electrolyte disposed between the positive and negative electrode materials. The polymer electrolyte is formed by mixing a vinylidene fluoride copolymer and a nonaqueous electrolytic solution with a solvent, followed by evaporation of the solvent, so as to retain a high proportion of the nonaqueous electrolytic solution, leading to high electroconductivity and excellent strength in this state. The vinylidene fluoride copolymer comprises 80 to 97 wt. % of vinylidene fluoride monomer units and 3 to 20 wt. % of units of at least one monomer copolymerizable with vinylidene fluoride monomer, and has an inherent viscosity of 1.7 to 7 dl/g, as measured at 30° C. in a solution at a concentration of 4 g of polymer in 1 liter of N,N-dimethylformamide.
