Abstract: Disclosed are an R—Fe—B sintered magnet and a method for producing the same. More specifically, provided is an R—Fe—B (R=Nd, Dy, Pr, Tb, Ho, La, Ce, Sm, Gd, Er, Tm, Yb, Lu or Th) sintered magnet having a structure in which R2Fe14B crystal grains as major phases are surrounded with R-rich phases, wherein a dihedral angle between two adjacent R2Fe14B crystal grains and the R-rich phase contacting the R2Fe14B crystal grains is 70° or less in a triple junction formed by the R2Fe14B crystal grains. The sintered magnet maintains a high coercive force and exhibits improved mechanical properties and is thus applicable to motors or permanent magnets used at high temperatures.

Abstract: A discharge valve assembly of a reciprocating compressor comprises: a discharge valve for opening or closing a compression space for compressing a refrigerant in a cylinder; a valve spring for elastically supporting the discharge valve as its one end is connected to the discharge valve; a discharge cover provided with a support surface connected to the valve spring, and covering an end of the cylinder, receiving the discharge valve and the valve spring and simultaneously forming a discharge space of a refrigerant; and a buffer member attached to an outer mounting surface of the cylinder, for lessening an impact by contacting with the discharge valve before the discharge valve comes in contact with the cylinder to close the compression space of the cylinder. The buffer member absorbs the amount of an impact before the discharge valve contacts with the cylinder, thereby minimizing noise generation.

Abstract: A lift pin calibrator and a method of using the same set the height and orientation of a lift pin relative to a substrate support plate having a bore in which the lift pin is raised and lowered. The lift pin calibrator has a contact body, a pressure member and a tubular alignment member that are disposed coaxially. A pressure transmitting portion of the pressure member extends into an upper portion of the alignment member and the contact component extends through the pressure member so that an end of the contact component is left exposed by the pressure member. An outer diameter of the pressure transmitting portion of the pressure member is greater than an inner diameter of the alignment member. An extension of the alignment member is inserted into a bore of the substrate support plate. The pressure transmitting portion of the pressure member is forced into the alignment member to expand the alignment member and hold it in place.

Abstract: Disclosed is a densification process of a W—Cu composite material, and more particularly, a sintering method for a W—Cu composite material without exuding of Cu. The sintering method comprises the steps of: holding a W—Cu composite power compact for a certain time at a Cu solid phase temperature or at a temperature just above a melting point and thus inducing a nearly complete densification; and sintering for a short time at a Cu liquidus temperature.
