Title: Solvent system for an ionizable pharmacentical agent
Inventor: YU MAN-SUM
IPC: A61K9/00
Filed: 1987-10-15
Granted: 1994-07-14
Abstract: This invention relates to a solvent system for enhancing the solubility of an acidic, basic, or amphoteric pharmaceutical agent to produce a highly concentrated solution suitable for softgel filling or two piece encapsulation. The solvent system comprises polyethylene glycol containing 0.2-1.0 mole equivalents of an ionizing agent per mole equivalent pharmaceutical agent and 1-20% water. Glycerin or polyvinylpyrrolidone may be added to further enhance the solubility of certain drugs. The disclosed solvent system is capable of enhancing solubilities of pharmaceutical agents 40-400%. The ionizing agent functions by causing partial ionization (neutralization) of the free pharmaceutical agent. When the pharmaceutical agent is acidic, the ionizing agent is preferably a hydroxide ion species, whereas when the pharmaceutical agent is basic, the ionizing agent is preferably a hydrogen ion species. For amphoteric pharmaceutical agents, either hydroxide ion or hydrogen ion sources may be utilized to effect partial ionization. The disclosed solvent system is useful because it not only provides for the enhancement or improvement of bioavailability of acidic, basic and amphoteric pharmaceutical agents by delivering them already in solution, but it also provides for a highly concentrated solution capable of encapsulation in a small enough vessel to permit easy swallowing. The highly concentrated solid solutions of the present invention are also useful for conversion into tablets and as veterinary spot and pour on preparations.

Title: Pll locktime control apparatus
Inventor: PARK CHAN-HYON
IPC: H03L7/00
Filed: 1990-11-28
Granted: 1993-08-31
Abstract: The circuit is for reducing a locking time in the high  speed digital  communication  equipment's  PLL  unit.  In  general,  the locking time delay is caused by the necessary stablization time in the transient response of the loop filter. In order to lock a  new channel, the wanted channel data is loaded into the D/A  converter (30). The D/A converter output voltage is  divided  into  the  two reference voltage-Vref1  and  Vref2.  Uncompensated  input  signal voltage from the loop filtering circuit (20) is compared with  the above reference voltages. When the input voltage  level  is  below Vref1, then it increases a control input voltage of the  VCO  (3). And, when the input voltage is above Vref2, it decreases VCO (3)'s control input to reach a target level quickly.

Abstract: The present invention relates to an improvement in a lining method for internal surfaces of pipes in multi-branched pipings such as water pipes, gas pipes, etc., in which a plurality of branched pipelines (1a) are branched from a main pipeline (1) and particularly to a shaping method for a lining surface. In a multi-branched piping in which a plurality of branched pipelines (1a) are branched from a main pipeline (1), a coating is poured into a pipeline from one end of the main pipeline (1) or each of the branched pipelines (1a), gas is then fed to thereby line the internal surface of the pipeline, a sponge consisting of an elastic foam body (P) having a larger diameter than the inside diameter of the pipe (1) constituting the pipeline (1), said foam body (P) being made of synthetic resin and having a continuous foam, is inserted from an end of each branched pipeline (1a) and the sponge is then pushed with the aid of air pressure whereby the lining surface can be shaped to have substantially uniform film thickness. <IMAGE>

Abstract: The coil device is useful for  an  electric  fan  heater,  or electric hot water heater, which needs both a heat  source  and  a dynamic power. This device has a structure  which  generates  high heat and  magnetism  simultaneously.  High  resistance  conductive wires (1)(1') are coated by the insulation material and are  wound in a ring shape or  square  shape.  The  heat  and  the  magnetism generating ratio are controlled freely by the  winding  ring  size and the coil thickness.
