Title: Thyristor convertor
Inventor: IWAJI YOSHINAO
IPC: H02M7/12
Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To reduce harmonic components, which are generated in the input current of a thyristor converter and which are expressed by a specific expression by providing a single-phase AC power supply by which either an AC voltage or an AC current whose frequency is at a specified multiple of the frequency of a three-phase AC power supply is applied to the output end of the thyristor converter. SOLUTION: The waveform of the output voltage of a single-phase AC power supply 7 is a square wave, whose frequency is six times the frequency of input voltages of thyristor converters 4, 4', and its peak value is set at a prescribed value. When the voltage at the square wave is applied to output voltages of the thyristor converters 4, 4', output currents Icon1, Icon2 are shaped into a current waveform of a triangular wave. The peak value on the lower side of a current value is adjusted so as to come exactly to Icon1=0 and Icon2=0. As a result, in input currents Iu1, Iu2 of the thyristor converters 4, 4', harmonic components which are expressed by  6 m ± a first order, m=1, 3, 5,...} is increased, also an overall distorsion factor is increased, and a harmonic component which is expressed by  12 ± a first order, n=1, 2, 3,...} is reduced.

Title: Manufacture of silver oxide battery
Inventor: SAWAI TADASHI
IPC: H01M4/54
Filed: 1982-06-10
Abstract: PURPOSE:To enhance the electric discharge capacity of a silver oxide battery by increasing the packed amount of a positive active material, and enhance the reliability during preservation of the battery by reducing granular silver oxide by use of a reducing matter to form silver metal layers over the surfaces of the granular silver oxide, and then preparing a positive electrode from the thus obtained matter alone. CONSTITUTION:After the surface of granular silver oxide are reduced by a reducing matter to form silver metal layers, the thus obtained grains alone are packed into a nickel-plated iron positive case 2 to form a positive electrode 1. Since there is no need to add graphite as a condictive member, the amount of a reactive active material packed into the positive case 2 can be increased. Since the surfaces of the granular silver oxide are converted into silver metal, there is no possibility that silver oxide, having a strong oxidative effect, and a separator layer 4 directly touch one another, resulting in a small oxidative deterioration of the separator alayer 4, and the preservation characteristic of the battery is stabilized. The grain size of the granular silver oxide should be within the range of 50-500 mesh.
