Title: Row active method of semiconductor memory device
Inventor: HAN JONG HUI
IPC: G11C11/409
Filed: 1999-12-30
Abstract: PURPOSE: A row active method of a semiconductor memory device is provided to reduce a power consumption in the memory device. CONSTITUTION: If a power is applied to a semiconductor memory device, a power supply voltage(VDD) is applied to a bit line selection signal line(Bls_up/Bls_down). If a memory cell array block(MCA(i)) is selected and activated, a voltage level of the bit line selection signal line is increased from the power supply voltage level to a high voltage(VPP) level. On the precharging operation, the bit line selection signal line maintains the high voltage level. If the memory cell array block is inactivated and another memory cell array block(MCA(i-1)) is activated, the voltage level of the bit line selection signal line becomes a ground voltage level, and the voltage level of the bit line selection signal line becomes the power supply voltage level by the input of a precharge command. If the memory cell array block(MCA(i-1)) is activated under the state that the voltage level of the bit line selection signal line is the power supply voltage level, the voltage level of the bit line selection signal line is decreased from the power supply voltage level to a ground voltage level.

Abstract: PURPOSE: Provided are purified proteins, recombinant DNA sequences and processes for controlling the ripening of coffee plants. CONSTITUTION: Purified proteins, DNA sequences that code on expression therefore and recombinant DNA molecules, including hosts transformed therewith for transforming coffee plants to suppress the expression of enzymes necessary for ethylene synthesis. The DNA sequences and recombinant DNA molecules are characterized in that they code on expression for the enzymes ACC synthase or ACC oxidase that are elements of the pathway for ethylene biosynthesis in coffee plants. Coffee plants are transformed with vectors containing ACC synthase and/or with ACC oxidate DNA sequences that code on expression for the respective mRNA that is anti sense to the mRNA for ACC synthase and/or ACC oxidase. The resulting anti sense mRNA binds to XMI mRNA, thereby inactivating the mRNA encoding one or more enzymes in the pathway for ethylene synthesis. The described DNA sequences can also be used to block synthesis of ACC synthase or ACC oxidate using co-suppression. The result in either event is that the transformed plants are incapable of synthesizing ethylene, though other aspects of their metabolism is not affected

IPC: G06F19/00
Filed: 1998-05-27
Abstract: The invention concerns a mechanical part with abrasionproof surface characterized in that it comprises a sintered metallic body obtained from metallic powders and a laser-deposited cermet coating. The coating has a certain thickness whereof a portion is metallurgically bound with the metallic body. The laser deposit enables the sintered part to be surface-melted under the effect of the laser beam. The surface of the sintered part to be coated is therefore fused over a thickness ranging between 10 mum and 1 mm, which enables the surface pores to be closed, as is characteristic of sintered parts, thereby increasing its resistance to shocks. Moreover, the small surface coated at a given moment by the laser enables the self-hardening of the exposed part, following the beam displacement, by the heat-sink effect of the surrounding metallic volume. The resulting coating also has very low porosity owing to the complete fusion of the powders by laser.
