    摘要: A valve device includes a control device adapted to control a valve without being supplied with electricity. The control device includes at least one rotatable control cam having an outer periphery with a concave and convex shape, and a driving device adapted to rotate the control cam only in a first rotational direction, out of the first rotational direction and a second rotational direction opposite from the first rotational direction, by being supplied with a pressurized medium. The valve is placed such that a switch portion comes in contact with the outer peripheral portion of the control cam, in order that the valve is opened and closed by the control cam being rotated.

    摘要: An electric heating device includes a control portion adapted to control electric energy supplied to a heater, based on a before-heating temperature, which is a temperature of at least one of an object, the heater and a heat dissipation portion before the heater generates heat, the control portion is adapted to calculate the temperature of the object, based on the before-heating temperature and the electric energy supplied to the heater.
