Inventor: BAXI INDRA R
IPC: B29C45/17
Filed: 1988-11-17
Granted: 1996-05-23
Abstract: In a process for producing an injection molded product, a stream of plastic material is introduced into a mold space 11 at a first pressure. Gas is stored in a storage chamber 28 at a second pressure which is at least as high as the first pressure. The gas is introduced into the molten stream of plastic material immediately after the molten material has passed the position at which the gas is introduced thereby forming a gas cavity in the molten material. The gas exerts pressure on the surrounding plastic material to urge the material toward the surfaces of the mold space. As the feeding of the plastic material into the mold space continues, the injection of the gas is also continued. The supply of molten material is terminated when the surfaces of the mold space are completely covered by the molten material. A pressure is held within the gas cavity as the plastic material cools. Subsequently, the pressure is released to bring the gas cavity to ambient pressure. The the mold 9, 10 is opened to remove the hollow shaped article. An apparatus for producing an injection molded product is also disclosed.

Abstract: The  circuit  is  to  charge  batteries  rapidly   using   a microcomputer. The charge program  is  coded  to  simplify  charge circuit  and  to  improve  reliability.  The  circuit  includes  a microcomputer (5) for controlling charge  current  by  controlling output of a switching mode power supply (10), a  voltage  feedback unit for feeding battery voltage back  to  an  analog  to  digital converter  of  the  microcomputer,  and  a  power  controller  for controlling charge current flowing  into  batteries  according  to minus delta V of battery detected by the microcomputer.

Title: Fifo buffer control circuit of 16bit dual port for small computer system interface
Inventor: LEE JUNG-KEUN
IPC: G06F13/36

Granted: 1991-12-05
Abstract: The first input first output (FIFO) buffer  has  the  16  bit access structure to improve  the  efficiency  and  the  duad  rate between a system memory and  a  small  computer  system  interface (SCSI) unit. The data transmission  between  the  dual  port  FIFO buffer and the system memory (1) is executed by  16  bit  and  the data transmission between the dual port FIFO buffer  (3)  and  the SCSI bus controller (5) is executed by 8 bit to enlarge  the  band width of the system bus. A dual port FIFO buffer control logic (4) is used to improve the transmission efficiency.

Title: Process for making the material for non-magnetic roll for continous casting
Inventor: YU HO-CHON
IPC: C21D7/00

Granted: 1992-09-19
Abstract: The high-strength non-magnetic  roll  material  comprises  by wt.%, 0.10-0.20 C, up to 1.0 Si, 20-30 Mn, up to  0.03  P,  up  to 0.010 S, 2.0-4.0 Cu, 1-3 Cr,  1-3  Mo,  and  the  balance  Fe  and inevitable impurities. After heating at 1250-1350 deg.C, the steel is heat- rolled  at  1200-900  deg.C.  The  roll  material  has  an austenitic structure stabilized by adding 2-4 % Cu and 1-3  %  Mo. The yield strength  and  tensile  strength  of  the  material  are enhanced. And   acid   resistance,   high-temperature   oxidation resistance, and welding property are enhanced.
