Title: Level shifter
Inventor: TSUBOI KOUKEI
IPC: H03K19/0185
Filed: 2002-05-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a level shifter which reliably operates, even at a low power voltage.  <P>SOLUTION: A first switch operates according to a control signal to receive an input signal. A voltage converter circuit converts the voltage of the input signal transferred via the first switch into a different voltage therefrom, to provide an output signal. A second switch connects an output node of the voltage converter circuit to a voltage line, corresponding to a voltage to be outputted by the voltage converter circuit according to the input signal. If, e.g. the input signal voltage exceeds a voltage range within which the voltage converter circuit properly operates, a voltage to be originally outputted by the voltage converter circuit is fed to the output node via the second switch. Thus the voltage of the input signal is converted surely to result in the level shifter operating surely, even at a low power voltage, and this prevents a semiconductor integrated circuit with the level shifter formed therein from malfunctioning.  <P>COPYRIGHT: (C)2003,JPO

Title: Silver-barium lead alloy for lead-acid battery grid
Inventor: VAZQUEZ DEL MERCADO LUIS FRANC
IPC: C22C11/06
Filed: 2002-05-22
Abstract: PROBLEM TO BE SOLVED: To provide an improved silver-barium lead alloy for use in the manufacture of a lead-acid battery positive grids, that improves ordinary temperature aging process required to attain hardness and strength required during pasting, hardening and subsequent processings of the battery grid. SOLUTION: The lead alloy for a lead-acid battery grid, essentially comprises calcium of about 0.05 to 0.07 wt.%, tin of about 0.09 to 1.3 wt.%, silver of about 0.006 to 0.010 wt.%, barium of about 0.0100 to 0.0170 wt.% and aluminum of about 0.015 to 0.025 wt.%, with the rest being lead. The lead alloy can improve an age hardening step, by dispensing with a high temperature treatment process required for a silver alloy, in the manufacture of a lead-acid battery. The use of the lead alloy prolongs a service life of the lead-acid battery further by increasing corrosion resistance and mechanical strength of a battery grid manufactured by a book molding method. A reduced silver level used drastically relieves a problem of silver removal from a recycled lead flow in secondary production of the metal.
