    摘要： A support member (10) for supporting a hoisting machine (9) disposed at a position close to the top within a hoistway (1) is supported at an upper end section of counterweight rails (6) which stand upright within the hoistway (1) and guide ascending and descending operation of a counterweight (8). In connection with such a construction, a coupling member (17) is provided between rail brackets (4)-which are spaced apart from each other in the vertical direction and fasten car rails (3) to fixing members (5) of the hoistway (1)-thereby coupling the counterweight rail (6) to the car rail (3). As a result, the displacement developing in the counterweight rail (6) in the direction orthogonal to the axis is transmitted to and supported by the car rail (3) by means of the coupling member (17). Consequently, occurrence of buckling in the counterweight rail (6) is prevented, thereby making the strength of the counterweight rail (6) close to that required to carry out a function of guiding the counterweight (8). The counterweight rail (6) can be reduced in size to a rail of standard size, thereby curtailing costs for constructing the elevator system.

    摘要： An armature winding is constructed by connecting an a-phase winding phase portion, a b-phase winding phase portion, a c-phase winding phase portion, a d-phase winding phase portion, and an e-phase winding phase portion into an annular shape so as to have a phase difference corresponding to an electrical angle of 72 degrees from each other. A rectifier is constituted by a five-phase full-wave rectifier formed by connecting in parallel five pairs of diodes connected in series. Output wires of the armature winding are connected to respective connection points of diodes connected in series on the rectifier. The predetermined number of field poles is 4n and the predetermined number of slots in the stator core is 5n, where n is a positive integer; and said five winding portions are wound not to span the slots.

    摘要： A failure diagnosis apparatus for a refrigerating cycle had a problem that it has a low precision because the fluid is treated, and it is difficult to detect a foretaste of failure, absorb individual differences of real machine in the failure determination, and determine a cause of failure. Also, no cheap and practical diagnosis apparatus and method are provided. A plurality of instrumentation amounts concerning the refrigerant such as the pressure and temperature of the refrigerating cycle apparatus or other instrumentation amounts are detected, the state quantities such as composite variables are acquired by making the arithmetic operation on these instrumentation amounts, and whether the apparatus is normal or abnormal is judged employing the arithmetic operation results. If learning is made during the normal operation, a current state is judged, and if learning is made by compulsorily performing the abnormal operation, or if the abnormal operating condition is operated during the current operation, a failure foretaste such as a critical operation can be made from a change in the Mahalanobis distance. Thereby, the secure diagnosis can be implemented with a simple constitution.
