    • To provide a heat pump apparatus, such as a heat pump water heating apparatus, capable of efficiently supplying high-temperature water by increasing a condensation capacity to a maximum if the outside air temperature is low. The heat pump water heating apparatus is configured to include a first refrigeration cycle and a second refrigeration cycle. The first refrigeration cycle is configured to connect in series a main compressor, a first water-refrigerant heat exchanger, an internal heat exchanger, a first pressure reducing device, and an air heat exchanger. The second refrigeration cycle diverges from the first refrigeration cycle between the first water-refrigerant heat exchanger and the first pressure reducing device, and joins the first refrigeration cycle between the main compressor and the first water-refrigerant heat exchanger. The second refrigeration cycle is configured to connect in series a second pressure reducing device, an internal heat exchanger, a sub compressor, and a third pressure reducing device.

    • Provided is a hinge device which, both before and after the change of friction torque, maintains the friction torque, and is prevented from axial lengthening. A shaft member is rotatably supported by a stationary-side bracket, a cam member is axially movable, with its rotation being restricted by the shaft member, a biasing element applies a bias in the direction toward the place where the cam member and the bracket contact each other to generate friction torque, and a convex portion and a concave portion are formed on the cam member and the bracket, respectively, to be fitted to each other. Either the convex portion and/or the concave portion is/are shaped such that the torque changes according to the rotation angle of the shaft member, and the biasing element has the inflection point of a spring constant between the maximum and minimum values of the torque.
    • 提供了一种铰链装置,其在摩擦转矩的变化之前和之后都保持摩擦转矩,并且防止轴向延长。 轴构件由固定侧支架可旋转地支撑,凸轮构件可轴向移动,其旋转受到轴构件的限制,偏压元件沿朝向凸轮构件和支架接触的位置的方向施加偏压 彼此产生摩擦转矩,并且凸轮部分和凹部分别形成在凸轮构件和支架上以彼此配合。 凸部和/或凹部均成形为使得转矩根据轴构件的旋转角度而变化,并且偏置元件具有在扭矩的最大值和最小值之间的弹簧常数的拐点 。
