Title: Variable-stroke swash plate type compressor
Inventor: TAKAO KUNIHIKO
IPC: F04B27/14
Filed: 1987-01-30
Abstract: PURPOSE:To improve durability by avoiding the contact between a drive plate and a sleeve and restricting the inclination angle between the drive plate and a swash plate. CONSTITUTION:The rotation of a drive plate 14 fixed to a main shaft 13 is transmitted from a lug section 141 to a swash plate lug section 14 to rotate a swash plate 12. When the swash plate inclination angle becomes largest, a conical surface 144 formed on the opposite side to the cam groove 142 of the drive plate 14 and the center of the main shaft 13 is brought into contact with a conical surface 124 formed on the swash plate 12. Accordingly, the inclination angle between the drive plate and the swash plate can be restricted, and the load applied to a sleeve pin can be reduced.

IPC: E01D11/04
Filed: 1991-02-12
Abstract: PURPOSE:To lengthen the lifetime of a cable by forming the support surface of an intermediate supporter supporting a section near an anchor in a paraboloid outward extended with separation from an anchor mouth section. CONSTITUTION:A supporter composed of an intermediate supporter 6 supporting a section near the anchor of a cable 1, an end section of which is fixed by the anchor 2, by a curved surface.

Abstract: PURPOSE:To enable to effectively commutate irrespective of the magnitude of the reactance at the power source side and the load side by detecting the commutation superposing angle from the both terminal voltages of a thyristor and the phase of a firing pulse, and setting the minimum firing angle by the detected value. CONSTITUTION:An AC power is converted by a thyristor converter 2 to a DC power to drive a winding motor 3. At this time the both terminal voltage of the thyristor 2 is detected by a detector 8, the commutation superposing angle is detected by a detector 9 from the phase of the firing pulse from a firing controller 13, compared with the value from a commutation superposing angle setter 10, the minimum firing advancing angle is increased by the minimum firing advancing angle setter 11 when becoming the prescribed value or larger, thereby controlling the thyristor 2. Accordingly, since the commutation superposing angle is not detected at the AC side, it is accurately detected irrespective of the magnitude of the reactance of the power source side and the load side, and a commutation failure can be eliminated even at the inverter operating time.

CONSTITUTION:A switch control circuit 16 receives a prior alarm signal 24 and a monitor antenna pair command signal 26 and simultaneously controls antenna pair thawing devices corresponding to a pair of monitor antennas. The signal from a switch B (8) is subjected to voltage vector synthesis by a synthesizer 9, and a high frequency output signal 10 subjected to differential synthesis from the synthesizer 9 is detected as a sound signal by a detector 12, and a high frequency output signal 11 subjected to summing synthesis is detected as a sound signal by a detector 12'. Sound signals from detectors 12 and 12' are outputted as a ratio of the summing synthesis output signal 11 to the differential synthesis output signal 10 by a divider 13. Consequently, the detection sensitivity to a subtle change of antenna characteristic is improved in comparison with the method where only the summing synthesis detection output or the differential synthesis detection output is compared with the prior alarm set signal.
