  • Patent number: 8481105
    Abstract: When forming an electrode by printing several times, the cross section area of the electrode is increased and the resistance is reduced while more electrode material is required, which leads to a cost up and waste of resources. There is provided a solar cell manufacturing method for forming an electrode of a predetermined pattern by repeating printing on a substrate surface by a predetermined number of times. A mask pattern for printing the entire predetermined pattern is used at least once among the predetermined number of printings while mask patterns, each for printing a part of the predetermined pattern, are used in the other printings, thereby forming the electrode of the predetermined pattern.

  • Patent number: 8397847
    Abstract: In an electric power converter for a vehicle which is connected to an alternating-current generator for a vehicle and performs synchronous rectification, switching mistakes are reduced and efficiency is improved by setting an optimal control allowance time in generating a switching timing signal from a diode ON signal. A control allowance according to the operating state of a generator can be determined by obtaining a control allowance time as a sum of a control delay time which is constant irrespective of the operating state of the generator, and an allowance time which varies depending on the operating state of the generator. Thereby, optimal switching timing is obtained and the reduction of switching mistakes and an improvement in efficiency are performed.
