Abstract: An electric staking die that joins a joined material to a shaping material, wherein a bump is formed in the shaping material, the bump is inlaid in a hole made in the joined material and the electric staking die presses a shaping portion that is a portion exserting from the joined material as well as a part of the bump, have a recess on a pressing surface that presses said shaping portion of said shaping material wherein an open hole of said recess is larger than said hole made in said joined material, has been offered. The volume of the recess room is more than the volume of the shaping portion of the shaping material. The manufacturing facility comprises a supporting table, the electric staking die and a control means. A method to carry out the electrical staking operation using the electric staking die is presented as sufficient strength staking.

Abstract: An improved continuous process for the synthetic preparation of imidazoline compounds is provided by the invention in which a mixture of an N-alkylol-substituted ethylenediamine and a higher fatty acid is supplied continuously to the upper part of a packed reaction column kept at 180.degree. to 250.degree. C. under a reduced pressure of 40 to 70 mmHg while the water formed by the condensation reaction is distilled out in parallel with the refluxing of the diamine and the reaction mixture, having stayed for at least 10 minutes in the reaction zone, is continuously discharged from the reservoir vessel installed below the reaction column to give the objective compound in a high yield.
