Abstract: An electric parking brake apparatus having an emergency releasing function for a vehicle, includes an actuator having a driven member, and an emergency release mechanism releasing a parking brake without relying on an electric motor and including an emergency driving member, and an operation mechanism, which is provided between an operation portion provided at the vehicle interior and the actuator and drives the emergency driving member, wherein the operation mechanism includes an operation driving member, which is movable relative to the emergency driving member so as to be engageable with and disengageable from the emergency driving member and drives the emergency driving member in a case where the operation driving member is engaged with the emergency driving member, and a positioning mechanism, which normally maintains an disengaged state of the emergency driving member and is provided at an end portion of the operation mechanism positioned closer to the actuator.

Abstract: A solution component recovery method, a solution component recovery apparatus, and an impregnation process/impregnation component recovery system for separating a first component from a second component. The separation between the first and second components is accomplished by reducing the pressure on a solution that contains the first component, which results in the solidification of the first component in the solution at a temperature that is equal to or higher than a predetermined solidification temperature. The second component, in which the first component is dissolved, is evaporated at a temperature range that is less than the predetermined solidification temperature. The evaporated second component is then recovered by a cooling step.
