  • Patent number: 11444353
    Abstract: A battery pack has bus bars, a battery stack which is an assembly of plural battery cells, a bus bar casing which supports a bus bar casing, and a cover member. Electrode terminals of battery cells adjacently arranged in the battery stack are connected together through the bus bars. An upstream side passage and a downstream side passage are formed between the bus bars and the cover member. Upstream side wall surfaces forming an inlet part of the upstream side passage or downstream side wall surfaces forming an outlet part of the downstream side passage is arranged at a location closer to the battery cell side than a location of a surface of the bus bar side.

  • Patent number: 6087287
    Abstract: A dielectric ceramic essentially in the form of an aggregate of crystal grains each having a ferroelectric core enclosed in a paraelectric shell. The shells are created by thermal diffusion of magnesium into the crystal grains. Through control of the firing temperature and time the thicknesses of the shells are confined in the range of approximately 5-30% of the average grain size. The resulting ceramic is low in dielectric constant and favorable in temperature characteristic of capacitance, making it suitable for use in laminated capacitors.
