Title: Industrial robot having a device for teaching a motor-driven arm with variable servo-control
Inventor: MARUO TOMOHIRO
IPC: B25J9/04
Filed: 1986-05-07
Granted: 1989-03-30
Abstract: This invention relates to a robot which can directly learn positions and motions by hand manipulations.  This robot comprises arms, an arm driving motor, a sensor for detecting the position of arm, a controller and a memory.  The controller consists of a servo-lock control part, a servo-lock shifting method, a positionsignal registration control part and a position-signal registrating method. The servo-lock control part permits the motor voltage which makes the difference between current position detected from the position sensor and the object position zero. In the position-signal registration control part, the output of the position sensor is registrated on the memory.

Title: Improvements in centrifugal grinding mills
Inventor: BOYES JOHN M
IPC: B02C17/14
Filed: 1985-07-23
Granted: 1990-11-26
Abstract: A centrifugal grinding mill including a grinding chamber of substantially circular cross-section with respect to an axis of symmetry and constrained to have nutating motion about a relatively stationary axis, a support for supporting the grinding chamber, a feed passage in communication with the grinding chamber, a driving assembly for driving the grinding chamber about the relatively stationary axis, and a constraint assembly for determining the form of nutating motion of the axis symmetry of the grinding chamber. The nutating motion of the grinding chamber during operation of the grinding mill causes a grinding charge carried in the grinding chamber to dilate and perform a tumbling motion within the grinding chamber. Further, the grinding chamber has a surface configured to exert pressure on the grinding charge so as to limit its dilation and provide effective containment of the grinding charge.

The lining is present on a underlying wall surface and is still hot from a previous use when one induces thermal shock in the lining (e.g. by spraying water on it) so as to loosen it. The loosened pieces are then pried away from the wall surface, and they are removed from the area. The residual lining is milled to expose a sound, underlying wall surface, and fine particles, dust, and milled-off pieces are removed. The underlying wall surfaces are thus made speedily available for relining and reuse.

Abstract: The  gas  mixing   device   comprising   bottles,   pressure regulators, check valves, and powermeters controls flux of gas  in parallel circuit and reduces the quantity of gas  consumption  and stabilizes power and spark of carbon laser. A pressure  switch  is connected between the bottle and the pressure regulator, and  each gate of the powermeter joins the bottle and 2-way  solenoid  valve of which the role is on/off switch of gas flow, and simultaneously a pressure  switch  which  controls  the  flux  of  gas  input  is connected between the bottle and the regulator. At the  outlet  of the bottle is placed a pressure gage, the pressure regulator,  the powermeter, a needle valve control motor,  2-way  solenoid  valve, and between the outlet of the  pressure  gauge  and  the  pressure regulator is placed a needle valve and 2-way  solenoid  valve  for keeping the pressure in cavity. To keep  a  atmospheric  pressure, 2- way solenoid valve is connected separately at the mouth  of  the needle valve.

Title: Dielectric composition of ceramic condenser
Inventor: AN BYONG-JUN
IPC: C04B35/48

Granted: 1993-07-21
Abstract: The  dielectric  ceramics  for  a  condenser  has   a   general formula, xPb(Mg1/3Nb2/3)O3-yPb(Zn1/3Nb2/3)O3-zPbZrO3-aSrTiO3, where 0.52<=x<=0.95, 0.00<=y<=0.05, 0.00<=z<=0.00, 0.10<=a<=0.22, 0.10<=a<=10.11 (x+y+z=1).  The dielectric ceramice is prepared by (a) mixing and pulverizing lead oxide, magnesia, noibium oxide, zinc axide, zirconia, strontium oxide and titania by a ball mill, (b) calcining the mixture at 750 deg.C for 2 hrs. and drying, (c) adding PVA as a binder to the dried mixture and molding, and (d) sintering at 950-1000 deg.C for 2 hrs. in the magnesia based container.
