    摘要: A small and thin pressing direction sensor that can continually detect pressing directions in the angle range of 360 degrees is provided. This pressing direction sensor includes a ring-like resistive film pattern, a first electrode pattern, and a conductive member that electrically connects the resistive film pattern and the first electrode pattern when pressed. The voltage of the first electrode pattern represents the pressing direction. This pressing direction sensor may further include a second electrode pattern. A signal representing the pressing force can be obtained from the second electrode pattern when the pressed conductive member is brought into contact with the second electrode pattern.

    摘要: A refrigerating system having a refrigerating cycle constructed by connecting an accumulator, a refrigerant compressor, a four-way valve, an outdoor unit heat exchanger, an outdoor unit expander, a receiver, an indoor unit expander and an indoor unit heat exchanger sequentially by pipes. Normally, excessive refrigerant is stored in the receiver and when it becomes necessary to raise a ratio of lower boiling point refrigerants, a flow amount of the refrigerant is decreased by restricting the outdoor unit expander during the cooling operation or by restricting the indoor unit expander during the heating operation to move the excessive refrigerant within the receiver to the accumulator. Thereby, the composition of the refrigerant circulating within the refrigerating system using non-azeotrophic refrigerant mixtures may be changed without using a complicated system structure or control method thereof and the capacity of the refrigerating cycle may be changed.
