Abstract: A functional molecular element is provided. The functional molecular element is adapted to change, by application of electric field, conformation of a disc shape like organic metallic complex molecule (1) which forms a columnar arrangement structure to exhibit function, wherein the structure of the organic metallic complex molecule is changed by application of electric field so that anisotropy of dielectric constant is changed. Accordingly, conductivity between measurement electrodes can be switched. As its stable value, there are three kinds of stable values or more. Thus, elements or devices to which such multi-value memory characteristic is applied can be constituted.

Abstract: In a direct current motor drive bridge circuit structured such that a pair of forward rotation switching elements and a pair of reverse rotation switching elements are alternately connected annularly, a direct-current motor is interposed between diagonal node points on one side, and a power source voltage is applied to a portion between diagonal node points on another side via an existing resistance. A fault detection apparatus of the direct-current motor drive bridge circuit is provided with a fault detection circuit for detecting an electric potential of the one node point r to which the power source voltage is applied via the existing resistance and for detecting a closed-circuit fault of the switching elements and on the basis of a fluctuation of the electric potential.

Abstract: A porous coordinatively unsaturated metal complex comprises metal complex units. Each metal complex unit includes a first metal and an organic ligand. The metal complex units are connected one another through a second metal (a connecting metal). The porous coordinatively unsaturated metal complex has voids formed by the connection. Voids have a size of 10 ? or more. The first metal is rendered to a coordinatively unsaturated state in the metal complex unit. With this arrangement, not only low-molecular weight compounds but also general compounds can be introduced as substrates. Further, the porous coordinatively unsaturated metal complex has high catalytic activity or high molecule retainability.
