  • Patent number: 10879015
    Abstract: A viologen compound is a crystalline compound including a heterocyclic moiety in which a carboxylate of an alkali metal is bound directly or indirectly to both ends of a basic skeleton containing 4,4?-bipyridinium and an anionic moiety that pairs with 4,4?-bipyridinium. The viologen compound can be used, for example, as a negative electrode active material for an electricity storage device including a negative electrode containing the negative electrode active material, a positive electrode containing a positive electrode active material capable of giving and receiving anions, and an ion-conducting medium that is disposed between the positive electrode and the negative electrode and conducts anions.

  • Patent number: 5642326
    Abstract: A dynamic memory comprises a control circuit for controlling the selection of the row decoder and the activation of the sense amplifiers in accordance with a RAS signal externally supplied thereto and a word line control circuit for controlling a selected word line to turn the electric potentials read out from the memory cells connected to the word line on the bit lines connected to the respective memory cells back to an inactive level after the electric potentials are sensed and amplified by the sense amplifiers corresponding to the respective bit lines during the time period from the time when the RAS signal is turned to an active level and the time when it is turned back to the inactive level. A dynamic memory has gate oxide films are designed to be subjected to a less electric field strength in order to minimize the degradation of reliability and the memory can effectively reduce the fall of the word line driving stepped-up voltage to eliminate the necessity of a leak current compensation circuit.
