  • Publication number: 20220282880
    Abstract: A control apparatus (40) controls an air conditioning system including: an internal conditioning machine which takes in air from inside of a target space, adjusts temperature of the air, and then outputs the air to the target space; and an external conditioning machine which takes in air from outside of the target space, adjusts temperature of the air, and then outputs the air to the target space. A setting unit (411) receives input of information regarding comfortability in the target space, and sets a target value for the comfortability. A controlling unit (413) controls both the internal conditioning machine and the external conditioning machine based on the target value set by the setting unit (411).

  • Patent number: 11391189
    Abstract: A link component (150) with an oil hole (150E) is attached to a crankshaft (106) of an internal combustion engine (E), and the oil hole (150E) allows communication from an outside to the crankshaft (106) side. The oil hole (150E) has an inclined surface (150F) along an opening rim on the crankshaft (106) side. A surface other than the oil hole (150E) has a carbon concentration of 0.5 wt % or more. The inclined surface (150F) has a carbon concentration within a range of 0.7 wt % or more and 0.9 wt % or less. Production cost is suppressed, and at the same time, damage is prevented by increasing resistance of the oil-hole part on which stress is liable to concentrate.
