Patent number: 5565651Abstract: A compactable composite explosive consisting of 90 weight % to 95 weight % of a raw explosive material being RDX, 5 weight % to 10 weight % of ethylene vinyl acetate copolymer resin containing vinyl acetate in a content of 10 % to 20 % and 0 weight % to 0.5 weight % of dioctyl adipate (D.O.A.) or graphite. This composite explosive is usable as a main charge or a booster of a highly precise arms system. The invention also provides a method for producing a compactable composite explosive, which comprises the steps of dissolving a binder of ethylene vinyl acetate copolymer resin in a solvent of toluene to prepare a solution, injecting the solution into RDX dispersed in a water, forming a granular product from the obtained mixture, distilling primarily the product, *adding toluene into the product, and distilling secondarily the product. The amount of added toluene is 1.0 time to 3.0 times the amount of the binder measured after the primary distillation.Type: GrantFiled: April 4, 1994Date of Patent: October 15, 1996Assignee: Agency for Defence DevelopmentInventors: Hyung S.

Patent number: 5530623Abstract: A memory packaging scheme for high speed computer systems includes, several memory module sockets mounted to a printed circuit board and interconnected by a common set of address, data and control transmission lines within the printed circuit board. The transmission lines are interrupted at each connector. Cooperating memory modules, such as SIMM memory modules are installed in sequence into one or more of the module sockets in accordance with the requirements of the computer system. Installation of a memory module into a memory socket closes the open circuits for each one of the transmission lines at the memory socket, extending the uninterrupted length of the transmission lines to the next memory socket in the sequence.Type: GrantFiled: November 19, 1993Date of Patent: June 25, 1996Assignee: NCR CorporationInventors: Ikuo J.

Patent number: 5503750Abstract: A substantially continuous membrane separation process has been discovered in which the known benefits of a cell-recycle fermentor are unexpectedly enhanced because pH is controlled from 4.0 to 5.5 with a nitrogen-containing base. The ammonium lactate formed is not precipitated, allowing continuous removal of lactic acid so as to maintain a concentration of lactic acid about 12% by wt in the broth. When combined with recycle of UF retentate, operating this cell-recycle fermentor allows the build-up of a cell population in the range from above 5.times.10.sup.9 CFU/ml to 5.times.10.sup.10 CFU/ml, which population is much denser than one which can be produced with the specified pH control in a batch fermentor, after self-termination of the fermentation. This super-dense population of cells, In turn, not only accelerates production of lactic acid but also minimizes contamination by foreign cells.Type: GrantFiled: October 4, 1993Date of Patent: April 2, 1996Inventors: Lawrence J. Russo, Jr., Hyung S. Kim

Patent number: 4866308Abstract: A high speed, high performance CMOS to GPI interface circuit is disclosed. The interface circuit contains an input stage, clamping circuitry, an output stage and feedback circuitry. The clamping circuitry clamps the voltage level presented to the output stage at a level below the power supply voltage when the input from the CMOS circuit is at a high logic level. As the voltage level of the signal presented to the CPI circuitry rises, feedback circuitry feeds this signal back to the clamping circuitry, which in turn decreases the voltage level presented to the output stage. This assures the signal presented to the GPI circuit falls within the specified voltage level from 1.51 and 2.2 volts. The feedback circuitry contains a single pole filter that filters out high frequency reflections presented to the feedback circuitry, and a slew rate limiter that slows the rise and fall of the voltage level presented to the output stage thereby reducing noise on the power supply and ground lines.Type: GrantFiled: April 11, 1988Date of Patent: September 12, 1989Assignee: International Business Machines CorporationInventors: Delbert R. Cecchi, Hyung S. Kim, John S. Mitby, David P. Swart, Balsha R. Stanisic, Philip T. Wu

Patent number: 4601278Abstract: A bullet is fired from an ammunition cartridge upon piercing a breakaway section in the rear wall of the cartridge to form a gas escape port. The cartridge has one open end in which is seated the bullet and the breakaway section of the rear wall is directly opposite the bullet. A moveable sealing element is adapted to move between two positions. One position seals off the opening in the one end, and the other position is displaced from the opening to allow gas to escape under pressure from the opening. Piston-type element, in response to the housing wall being pierced, stops the flow of gas from this escape port and moves the sealing element from the first to the second position.Type: GrantFiled: June 24, 1983Date of Patent: July 22, 1986Inventor: Hyung S.
