  • Patent number: 6574579
    Abstract: A waveform generating apparatus capable of outputting a desired waveform is provided. Among delay data is selected a set pulse generating delay data depending on test logical data and waveform mode information. The delay data, a skew adjusting delay data, and a fraction data in each test cycle are computed to obtain an integer delay data and a fraction delay data, which are supplied to a counter delay circuit. From the counter delay circuit are outputted a set pulse generating effective flag for delaying a test period timing by a delay time corresponding to the integer delay data, and a fraction delay data related thereto. The effective flag is delayed based on the related fraction delay data to obtain a set pulse. Similarly with the set pulse, a reset pulse is obtained, thereby to set/reset an S-R flip-flop to output a desired waveform.

  • Patent number: 5958362
    Abstract: The present method is to produce an active material powder formed of a spinel oxide containing lithium or a layer-structured oxide containing lithium for a lithium secondary battery which is uniform in composition, fine in particle size and free of oxygen defects, and which is unlikely to cause capacity deterioration resulted from repetitive charge/discharge cycles at a high current density.A suspension 1 prepared by suspending an ingredient of the active material powder in a combustible liquid or an emulsion prepared by emulsifying a solution of the ingredient in the combustible liquid is sprayed in a droplet state 15 together with an oxygenic gas 2. The combustible liquid contained in the droplet 15 is burned to have the ingredient therein reacted and to evaporate the solvent. As a result, active material powder 4 formed of the spinel oxide containing lithium is obtained.
