Title: Packaged integrated circuits
Inventor: KILBY JACK S
IPC: H01L23/29
Filed: 1993-09-13
Abstract: HERMETICALLY SEALED INTEGRATED CIRCUITS                           ABSTRACT           The present invention provides hermetically sealed integrated circuits which can have a standardized arrangement of external contacts.  These circuits comprise a circuit subassembly having external contacts.  Onto the surface of the subassembly surrounding the external contacts is formed a first ceramic passivating layer.  Next, a non-corroding, conductive layer is formed on the external contacts and portions of the first ceramic passivating layer.  Then a second ceramic passivating layer is formed on the non-corroding, conductive layer and that portion of the first passivating layer not covered by the non-corroding, conductive layer.  Finally, the second passivating layer is etched through to the conductive layer to allow external contact with the circuit.  The present invention also relates to methods for producing the above integrated circuits.

Title: Cell differentiation inducer comprising acyclic polyisoprenoid
Inventor: TSURUMI HISASHI
IPC: A61K31/20
Filed: 1994-03-07
Abstract: Abstract To provide a remedy or ameliorant, based on the effect of inducing cell differentiation, for diseases such as hematopoietic organ tumors and solid tumors for which no clinically highly useful drug has been known hitherto.  The fundamental idea of the conventional pharmacotherapy for cancer resides in completely exterminating tumor cells having an unusually high capability of multiplication.  However these treatments also had toxicities against normal cells and thus grave side effects were unavoidable.          Further, only limited therapeutic effects could be achieved.  On the other hand, although all-trans-retinoic acid had a remarkable effect on acute promyelocytic leukemia, there was reported that this compound also had grave side effects.  Further, there was another problem that the diseases tended to recur after it was healed.  In contrast, (2E,4E,6E,10E)-3,7,11,15-tetramethyl-2,4,6,10,14-hexadecapentaenoic acid has an unexpected effect of inducing cell differentiation and a high safety.  Being different in structure from all-trans-retinoic acid, this compound has a high possibility of preventing the recurrence of the disease.  Therefore, it is expected as a clinically useful remedy or ameliorant for hematopoietic organ tumors, in particular, acute promyelocytic leukemia and myeloid dysplasia syndrome.

Title: Method of sequential subprocesses in a flow consecutor to replace an overall process in a vessel with agitated fluid
Inventor: PETELA RYSZARD
IPC: B01J19/00
Filed: 1994-03-11
Abstract: A method is proposed to replace a complex processes which a fluid undergoes while it resides in a vessel such as a stirred tank or a reactor, by the  sequentially arranged subprocesses which the said  fluid  undergoes  while  it  flows  through  the  proposed apparatus.  The  said  sequential  subprocesses  occur  in  the consecutive sections of the proposed apparatus called the "Flow Consecutor".          The sequential organization of the said subprocesses in a fluid flowing at a high rate through the Flow Consecutor results in a significant reduction of the overall time of the process. Also, it provides possibility of control of parameters for each of the subprocesses on the individual basis. Therefore, the optimization of the overall complex process efficiency is replaced by the optimization  of  each  of  the  subprocesses  what  increases substantially the process overall efficiency.          Sample  applications  of  the  proposed  method  for  selected industrial processes are demonstrated. The scale-up criteria and design procedure for the apparatus are also described.

Title: Small system for precision ultra-sensitive trace mass spectroscipy of carbon-14 and other selected nuclides
Inventor: SCHUBANK RONALD B
IPC: H01J49/28
Filed: 1994-09-13
Abstract: A method of measuring in small samples the ultra-trace amounts of C-14 relative to C-12,13 in a background of N-14, comprises the following steps: the sample isphysically and chemically processed depending upon the final sensitivity desired; the sample is injected into an ICP, which functions as a source of positive ions with energies up to a few tens of KeV, and as a molecular dissociator of order parts-per-trillion; the ions then analyzed with conventional Electrostatic and Magnetic spectrometers, which monitor the ion beams with adjacent masses and transmit the ion species of interest through defining apertures; the transmitted ions are re-foccused and accelerated to an energy of order tens of KeV; the positive ion beam strikes a thin foil or supersonic gas-jet canal where some of the beam intensityemerges with negative charge, eliminating atomic isobar backgrounds that cannot form negative ions, and as an additional molecular ion dissociator; the transmitted Negative ions are refoccused and accelerated by a few more tens of KeV; the ionsare then analyzed with conventional Electrostatic and Magnetic spectrometers, through a final defining aperture and onto a detector. Similar configurations may be used to measure ratios of other long-lived radio- to stable-isotopes whose com-peting stable atomic mass-isobars cannot form negative ions, such as: 26Al/27Al in a background with 26Mg; 55Fe/54Fe in a background with 55Mn; 129I/127I in a background with 129Xe, Similar configurations may be used for direct measure of platinum group elements (PGE), actinides (ACT), etc., when atomic-isobars need not be distinguished.
