  • Publication number: 20250036931
    Abstract: The node includes a first input terminal, a second input terminal, a first sample and hold circuit, and a first output terminal. The first input terminal is configured to be connectable to an input source for transmitting an input signal to a reservoir device. The second input terminal is configured to be connectable to at least one other node. A first terminal of the first sample and hold circuit is connected to the first input terminal and the second input terminal. A second terminal of the first sample and hold circuit is connected to the first output terminal. The first output terminal is configured to be connectable to at least one other node. The first sample and hold circuit holds and converts a joined signal of the input signal and a propagated signal from the second input terminal.

  • Patent number: 6139991
    Abstract: An electrolyte solution for a lithium secondary battery comprising a non-aqueous solvent, and an electrolyte and a carbonic ester derivative both dissolved therein, said carbonic ester derivative having the formula (I): ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 independently represent an alkyl group having 1 to 12 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms, or an aryl group having 6 to 12 carbon atoms, provided that R.sup.2 may be a hydrogen atom and provided that R.sup.1 and R.sup.2 may be connected through a methylene group to form a cycloalkyl group having 3 to 6 carbon atoms.

  • Patent number: 6033809
    Abstract: A non-aqueous electrolyte lithium secondary battery comprising a cathode, an anode and a non-aqueous electrolyte comprising an electrolyte dissolved in a non-aqueous solvent, wherein the cathode is composed of a material containing a lithium complex oxide, the anode is composed of a material containing graphite and the non-aqueous solvent contains, as main components, a cyclic carbonate and a linear carbonate and 0.1 to 4% by weight, based upon the total weight of the non-aqueous solvent, of a sultone derivative having the general formula (I): ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 independently represent an alkyl group having 1 to 12 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms, an aryl group having 6 to 12 carbon atoms or a hydrogen atom and n is an integer of 0 to 2.
