  • Patent number: 11279899
    Abstract: A grease composition for a constant-velocity joint includes a mineral oil, a thickener, a molybdenum dithiocarbamate, a potassium borate hydrate, and a zinc dialkyldithiophosphate, wherein a content of the molybdenum dithiocarbamate is 1.2% by mass or more and 8% by mass or less, a content of the zinc dialkyldithiophosphate is 0.3% by mass or more and 2.0% by mass or less, and a content of the potassium borate hydrate is 0.28% by mass or more and 1.9% by mass or less, and wherein a mass ratio of the content of the molybdenum dithiocarbamate to the content of the potassium borate hydrate (molybdenum dithiocarbamate/potassium borate hydrate) is 2 or more and 13 or less, and a mass ratio of the content of the zinc dialkyldithiophosphate to the content of the potassium borate hydrate (zinc dialkyldithiophosphate/potassium borate hydrate) is 0.5 or more and 3.6 or less.

  • Patent number: 10215107
    Abstract: A display apparatus includes: a variable compression ratio mechanism which is capable of modifying an engine compression ratio of an internal combustion engine and a display displaying a state of a present engine compression ratio. For example, when a driving at an engine compression ratio with a good fuel economy is carried out, a display switching is not unnecessarily carried out even under a vehicular acceleration and the display can cause a driver to be recognized that the driving is carried out in a good fuel economy state. On the other hand, when the driving state is switched from the driving state of good fuel economy to that of a bad fuel economy due to an abrupt depression of an accelerator pedal, the display of the engine compression ratio is accordingly varied.

  • Patent number: 7089921
    Abstract: An intake manifold (1) of a multi-cylinder internal combustion engine comprises a single pipe portion (4), a collector (5) connected to the pipe portion (4), and a plurality of branch pipes (6) branching from the collector (5) to each cylinder. The pipe portion (4) and the collector (5) divided into a plurality of spaces (1a, 1b) by a partitioning member (12). Blow-by gas is equally distributed to each cylinder using a simple structure comprising a discharge vent (3) for blow-by gas in the pipe portion (4) extending over the partitioning member (12) and being equal to the two spaces (1a, 1b). It is preferred that a notch (8) is formed facing the discharge vent (3) on the partitioning member (12).
