Abstract: Some embodiments of this specification provide a secure multi-party computation method and apparatus. According to the method in these embodiments, first, a TEE node cluster including K TEE nodes is joined based on a quantity N of data owners; then, a trusted execution environment is created in the TEE nodes, and a basic algorithm for secure K-party computation is loaded into the trusted execution environment; next, at least one data fragment is obtained from the trusted execution environment; and finally, secure K-party computation is performed by using the basic algorithm for secure K-party computation and the obtained data fragment.

Abstract: A compressor includes: a housing including a cylindrical body, and a first cover and a second cover which are respectively arranged at two axial ends of the cylindrical body; a compression mechanism accommodated in the housing and constructed to compress a working fluid; a crankshaft constructed for driving the compression mechanism; a motor constructed to drive the crankshaft to rotate; and a bearing block accommodated in a space defined by the motor and the housing and fixedly attached to the housing, wherein the bearing block is constructed to rotatably support the crankshaft by means of a bearing. The housing is provided with a cylindrical reinforcing portion used for defining a space, and the rigidity of the cylindrical reinforcing portion being greater than that of other parts of the housing. The structure can significantly reduce noise radiation and reduce manufacturing processes and costs.

Abstract: Disclosed are a scroll compressor and a method for assembling a non-orbiting scroll of the scroll compressor. The scroll compressor includes: a scroll mechanism including a non-orbiting scroll which includes a non-orbiting scroll end plate and a non-orbiting scroll wrap and an outer peripheral wall; and a main bearing seat for supporting the scroll mechanism including a main body part and an axial seat portion whose inner peripheral surface is formed with a circumferential annular groove. The scroll compressor further includes an elastic ring provided between the outer peripheral wall and the axial seat portion and a push structure for forcing the elastic ring to expand radially outward, so that a part of the elastic ring in a radial direction is inserted into the circumferential annular groove to limit axial movement of the non-orbiting scroll away from the main bearing seat.

Abstract: A compressor may include a compression mechanism, a driveshaft, and an oil allocation member. The driveshaft drives the compression mechanism and includes a lubricant passage having an inlet and first and second outlets. The first outlet is disposed vertically higher than the inlet and the second outlet is disposed vertically higher than the first outlet. The oil allocation member is disposed within the lubricant passage. The oil allocation member may define first, second and third channels. The first channel extends through a lower axial end of the oil allocation member. The second channel receives a first portion of the lubricant from the first channel. The third channel receives a second portion of the lubricant from the first channel. The first and second portions of the lubricant may be separated from each other at a location that is vertically higher than the first outlet.
