Title: Method for making thixotropic materials
Inventor: BUSK ROBERT SCHOLLEY
IPC: B22C17/08
Filed: 1982-12-01
Granted: 1987-07-13
Abstract: Liquid-solid metal alloy is produced by heating an alloy of dendritic structure to between its solidus and liquidus temp. and subjecting the alloy to shearing action to break up the dendritic structures. Shearing may be effected by an extruder or an injection moulding machine, pref. a reciprocating screw injection moulding machine. Thixotropic alloy contg. up to 65%wt.% solids, for use in injection moulding, forging or die casting processes, is produced without having to heat the alloy to above its liquidus temp.

IPC: G01C19/02
Filed: 1984-04-26
Granted: 1989-08-05
Abstract: A structure supporting a mirror comprises two frames which are mobile in elevation and azimuth.  Motors drive the respective frames to orientate the mirror.  The azimuth frame supports a gyroscopic wheel which has two degrees of freedom ensured by a universal joint comprising two crossed frames.  Detectors sense the axis w.r.t. the azimuth frame and precession motors apply procession torque to the wheel.  Signals from the detectors enable the axis orientation of the wheel to be determined w.r.t. the demand axis.  Signals for elevation and azimuth are introduced by the operator for processing by electronic circuits.

Title: Dressing checking method of grinder
Inventor: SONG SU-BOK
IPC: B24B53/00
Filed: 1991-06-05
Granted: 1993-04-26
Abstract: The testing method accuratly controls the size of the dressed grindstone without depending on  the  exterior  test  through  the human sight in the conventional method. The jig for realizing  the method comprises a base (1) forming a rectangular  groove  (2)  at one  side;  fixtures  (4),  for  fixing  grinding  material   (3), positioned on the  upper  part  of  the  base  (1);  the  grinding material fixedly inserted into the groove (2) of the base (1)  and having a grinded groove (7). The  accurate  size  of  the  dressed grindstone (6) can be adjusted by measuring the grinded groove  by use of a conventional tester, i.e. projector.

Title: Electric wave absorber
Inventor: KIM KYONG-YONG
IPC: H01F1/34
Filed: 1991-08-13
Granted: 1993-12-10
Abstract: The method for mfg. a radio wave absorber is characterized by mixing 66.1 g Fe2O3, 23.1 g ZnO, 8.8 g NiO,  0.5  g  MnO2,  0.5  g Co3O4 and 1.0 g CuO, (b) drying  and  crushing  the  mixture,  (c) calcinating it at 900 deg.C for 2 hr, (d)  crushing  and  moulding it, (e) heating it to the heating rate of 2-12 deg.C/min upto 1250 deg.C for 2-6 hr, and (f) cooling it to the cooling rate  of  2-12 deg.C/min to obtain a ferrite sintered body (Ni-Zn).

Title: Module connecting common manufacturing automation protocol
Inventor: KIM HYON-KI
IPC: G06F13/14
Filed: 1991-12-11
Granted: 1994-04-20
Abstract: The module serially connects a Mini-MAP network and an RS-232C interface to a programmable device to produce the remote control monitoring function of the programmable device which connects to the general purpose MAP connection module. The module includes a main control unit (MCU) which has a microprocessor, a network interface unit (NIU) which has the function of communication, a serial input output device (SIO) which has the function of connecting to the program mable device console, and a power suppy unit. The functions of MCU are the network console function, SIO port application control program, and program diagonistic function.
