  • Patent number: 10427465
    Abstract: A pneumatic tire include a tread portion with a designated installing direction to a vehicle to define an outboard tread edge and an inboard tread edge, the tread portion including an inboard portion defined between the inboard tread edge and a tire equator and an outboard portion defined between the outboard tread edge and the tire equator. The inboard portion is provided with a circumferentially and continuously extending first main groove and a circumferentially and continuously extending second main groove arranged between the first main groove and the inboard tread edge. An axial distance from the tire equator to a centerline of the second main groove is in a range of from 0.35 to 0.75 times of a width of the inboard portion. No circumferentially and continuously extending main grooves are provided with the outboard portion.

  • Patent number: 8674253
    Abstract: According to an embodiment, a gas insulation apparatus (e.g., a gas circuit breaker) includes a high-voltage unit, a zeolite and an insulation gas in a closed vessel. The insulation gas is CO2 gas or a gas including CO2 gas as the main component. The zeolite is contained in a zeolite case and is placed under an insulation gas atmosphere. CO2 is adsorbed on the zeolite before use of the gas insulation apparatus.
