Abstract: The present invention relates to a novel method for forming metal matrix composite bodies and novel products produced by the method. Particularly, a permeable mass of filler material or a preform (1) has included therein at least some matrix metal powder. Moreover, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are in communication with the filler material or a preform (1), at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform (1). The presence of powdered matrix metal in the preform (1) or filler material reduces the relative volume fraction of filler material to matrix metal.

Patent KR-920000694-B1 (KR)
Title: Process for producing dipeptides derivatives
Inventor: PARK BYUNG-WOOK
IPC: C07D207/16
Filed: 1989-12-28
Granted: 1992-01-20
Abstract: A method for preparing a dipeptide derivative of formula  (I) comprises (a) condensing an aminoacid deriv. of formula (II)  with a phenol deriv. of formula (III) to obtain arylester cpd., and (b) reacting the obtd. cpd. with L-proline sodium salt to form (I). In the  formulas,  X=O  or  S;  Y=H,  halo,  NO2  or  CN.  Pref.  the condensing-reaction is proceeded in the presence  of  dicyclohexyl carbodiimide as a condensing agent. Cpd. (I)  is  useful  for  the treatment of hypertension.

Title: Method of thin magnetic head
Inventor: JANG HAN-SONG
IPC: G11B5/33
Filed: 1989-12-29
Granted: 1993-07-21
Abstract: The method comprises (a) processing a plurality  of  first  tracks (2)  on ferrite block (1) and forming magnetic thin film (3) thereon, (b) processing a plurality of second tracks (4) and coil winding notches (5), and (c) coating the whole processed part with glass (6). More than one pair of coil winding notches are symmetrically formed on one ferrite block. The method can produce two kinds of magnetic head chip for chanel 1 and chanel 2 summultaneously and lessen the difference of track width during jointing of two ferrite blocks, while simplifying the manufacturing process and improving the product yield.
