    摘要： A highly reliable refrigeration cycle having a residual refrigerant, which is designed that the refrigerating machine oil does not stagnate in the refrigeration cycle after flowing out from the compressor even if the refrigerating machine oil is weakly soluble in a refrigerant. Thus, the compressor may be prevented from the exhaustion of oil. In addition to that, even if the accumulator is removed from the cycle, a large amount of wet vapor suction into the compressor may also be avoided. A control section is provided for controlling saturated oil solubility in a liquid refrigerant in the refrigeration cycle. The control section includes a receiver and first and second flow regulators which are placed before and after, respectively, the receiver. A residual liquid refrigerant obtaining in the circulation of a refrigerant is reserved in the receiver at a high temperature so that the weakly soluble refrigerating machine oil is prevented from separating.

    摘要： An SAW device substrate and an SAW device having a larger value of K2 than conventional SAW device substrates can be obtained by using LiNbO3 represented by Eulerian angles of (18-30°, 80-100°, 35-75°) and determining the thickness H of a piezoelectric substrate and the pitch &lgr; of electrodes so that KH is at least 2.3 and at most 4.5. Alternatively, an Li2B4O7 layer is formed as a piezoelectric substrate on a surface of a glass layer to obtain an Li2B4O7/glass structured SAW device substrate. More preferably, such Li2B4O7 that is represented by Eulerian angles of (0-45°, 85-95°, 85-95°) is employed. Furthermore, the SAW device substrate is used to form an SAW device so that the KH parameter is about 0.5.

    摘要： An SAW device includes a glass substrate, an LiNbO3 (LN) substrate, and an electrode. When a pitch of the electrode is &lgr;, a thickness of the LN substrate is H, and K equals to 2&pgr;/&lgr;, a product of K and H is at least 0.5 and at most 1.0. Accordingly, an SAW device is obtained which is provided with high K2 and an enhanced temperature characteristic and which can be advantageously reduced in size.

    摘要： A heat pump employing a capillary tube as an expansion device is disclosed. The main throttle portion of the heat pump comprises a main capillary tube and a by-pass through which a portion of the refrigerant flows and cools the refrigerant flowing through the main capillary tube. A solenoid valve for controlling the flow of refrigerant through the main capillary tube is connected to the intake of the main capillary tube, and an electrical expansion valve is connected to the intake of the by-pass for controlling the flow therethrough. An auxiliary capillary tube for cooling and an auxiliary capillary tube for heating are connected in parallel with the main throttle portion, both capillary tubes having a higher resistance to flow than the main capillary tube. The auxiliary capillary tubes increase the range over which control of the flow of refrigerant can be achieved, allowing both a smaller flow of refrigerant during under minimum cooling or heating load as well as a larger flow of refrigerant under maximum cooling or heating load.
