Title: Nonaqueous electrolyte battery
Inventor: FURUKAWA SANEHIRO
IPC: H01M6/16
Filed: 1988-03-11
Abstract: PURPOSE:To prevent drop of the low temp. discharge characteristic in the initial period and after preservation by using Li-Al alloy incl. Al in specific weight ratio as negative active substance, and by using trifluoromethane sulfonate lithium as solvent for electrolyte. CONSTITUTION:Li-Al alloy incl. Al in 0.1-20.0% by weight is used as active substance for a negative electrode. If trifluoromethane sulfonate lithium is used as solvent for non-aqueous electrolyte, the low temp, discharge characteristic in the initial period is enhanced, but fluorine ions are generated from the solvent during preservation. As the negative electrode consists of Li-Al alloy, the degree of activation is lower than in the case of Li solely, and therefore it is hard to react with fluorine ions. Accordingly production of a film in passive state on the surface of negative electrode is suppressed during preservation, and drop of the discharge characteristic after preservation is suppressed.

Title: Hydrogen gas detector
Inventor: TAMAMURA KOJI
IPC: G01N27/12
Filed: 1992-02-13
Abstract: PURPOSE:To detect a hydrogen gas even when the gas contains water by providing a gas sensor composed of a rare-earth magnet and detecting means which detects decline in magnetic force of the rare-earth magnet which occurs when the sensor comes into contact with the hydrogen gas. CONSTITUTION:A Hall element 20 is positioned in a magnetic field formed by a gas sensor 10. The Hall voltage generated across both ends of the element 20 is proportional to the magnetic flux density of the magnetic field. When the sensor 10 comes into contact with a hydrogen gas, the magnetic force of a rare-earth magnet drops. Therefore, the change in magnetic force changes the Hall voltage across both ends of the element 20 and, when the Hall voltage is measured with a voltmeter, the hydrogen gas can be detected and integrated. When it is required to install the sensor 10 in a gas pipeline 12, it can be done by positioning the element 20 in the magnetic field formed by the sensor 10 outside the pipe line 12. Or, it is also possible to add a magnet 22 to the outside of the pipeline 12 and position the element 20 in a magnetic field formed between the magnet 22 and sensor 10.

Title: Deciding method for coating deterioration
Inventor: SUGANO KENICHI
IPC: G01N27/26
Filed: 1979-05-16
Abstract: PURPOSE: To make it rapid and accurate to decide coating deterioration by supplying a fixed quantity of charge from a capacitor to a sample metal piece and then by finding the change of the resistance of a coating itself accompanying the coating deterioration of the metal piece as the voltage change of the capacitor.  
     CONSTITUTION: The capacity of capacitor C1 is made less than differential capacity CD of the electric double layer of a sample metal piece. With switch 6 closed, capacitor C1 where a fixed quantity of charge is accumulated starts discharging and the sample metal piece equivalent to equivalent circuit 1 is charged. The voltage V in this case is measured by voltage recorder 7 and its logarithm is plotted according to time to obtain a straight line and the capacity of capacitor C1 of previously- known capacity, by which coating resistance Rf can be found. When the deterioration of the coating is a little, coating resistance Rf is nearly equal to the previously- found resistance value of the coating itself and when the deterioration is in progress, a liquid immerses into the coating, so that coating resistance Rf will be a small value.
