Title: Method for preserving data in memory
IPC: G11C16/02
Filed: 1992-03-24
Abstract: PURPOSE:To prolong the service life of a memory by increasing the number of writable times of data. CONSTITUTION:Each time data to be stored in the memory are written, an ADR value is generated, the old data of an address corresponding to the ADR value generated last time are cleared, and updated data are written in an address corresponding to the ADR value generated this time. Since the memory is provided with plural addresses, the number of times for write to the respective addresses is decreased in comparison with the case of writing the data only in the same address and further, the service life of the memory can be prolonged since only the partial addresses are not used. The data can be used as the data showing the remaining amount of charging for a battery for device drive, in this case, the data of the remaining amount of charging can be written corresponding to the service life of the device, and only the service life of the memory is not reduced.

Filed: 1986-03-27
Abstract: PURPOSE:To ensure easy selection of an ink and enable high-speed recording, by applying both pulse-form electrical energy and pulse-form thermal energy to a liquid coloring agent, whereby the coloring agent in a region supplied with both the electrical energy and the thermal energy is caused to fly. CONSTITUTION:A liquid coloring agent 1 is disposed between a base electrode 2 and a counter electrode 3. An ink which is liquid at normal temperature and is so conditioned as to have, for example, an appropriate electrical resistance is used as the coloring agent 1. A predetermined voltage is impressed between the electrodes 2, 3 by a DC power source 4, thereby locally heating the ink 1. Namely, the temperature T1 of the ink 1 in a region S1 is made to be higher than the temperature T0 in other regions. In the region S1, the rise in the temperature of the ink causes a lowering in drag, and the action of a Coulomb's force is locally increased. An electric field is concentrated on the raised ink 1', and the Coulomb's force is exerted further strongly. Finally, a part of the ink 1' in the region S1 grows in a columnar form, and is torn off to fly toward the counter electrode.
