Patent CA-2002213-A1 (CA)
Inventor: TURLIK IWONA
IPC: H01L25/065
Filed: 1989-11-03
Abstract: A high performance integrated circuit chip package includes a support substrate having conductors extending from one face to the opposite face thereof and a multilayer wiring substrate on the opposite face of the support substrate for connecting chips mounted thereon to one another and to the conductors.  A heat sink includes microchannels at one face thereof, with thermally conductive cushions connecting the one face of the heat sink with the exposed back sides of the chips, to provide a high density chip package with high heat dissipation.          The multilayer wiring substrate may be formed by a self-aligned thin film wiring method, with a self-aligned lift off method being employed to form internal wiring planes.  The support substrate and heat sink may be formed of blocks of material having thermal expansion matching silicon.  The cushions are a low melting point solder, preferably pure indium, and are sufficiently thick to absorb thermal stresses, but sufficiently thin to efficiently conduct heat from the chips to the heat sink.

Abstract: Abstract of the Disclosure A polarization coupler in which a polarization maintaining fiber is employed and a process of producing such polarization coupler are disclosed.  Where the polarization coupler is used, beams of light from two laser diodes can be introduced into a single optical fiber and light for the monitoring can be split from a main signal output.  Since minimum components required to realize the function are a rotator, a birefringent plate and two or three polarization maintaining fibers, the polarization coupler is superior in operability in production and is suitable for the miniaturization.  The branching ratio of light for the monitoring can be adjusted by adjustment of the angle of rotation of light by the rotator.

IPC: A61K35/14
Filed: 1991-01-23
Abstract: PATENT         ABSTRACT OF THE DISCLOSURE         The development of cytolytic activity of lymphocytes can be potentiated by contacting the lymphocytes with antibody reactive with CD28 receptor, such as 9.3 monoclonal antibody.  The cytolytic activity thus potentiated is CD3 heteroconjugate-independent since targeting with a CD3 anti-target compound is not required.  The development of cytolytic activity can be further potentiated by also contacting the lymphocytes with antibody reactive with anti-CD2 antibody or immobilized antibody to the CD3 receptor, or by also contacting the lymphocytes with interleukin-2.  The CD28 receptor may be aggregated on the surface of the lymphocytes, as by crosslinking the antibody reactive to it on the surface of the lymphocytes.  This crosslinking can be by the use of a second antibody reactive with the anti-CD28 antibody.  Another aspect of the present invention is a method of adoptive therapy for treating cancer in a subject comprising the steps of: (1) contacting lymphocytes in vitro with an antibody reactive with CD28 receptor to potentiate the development of cytolytic activity of the lymphocytes to produce lymphocytes having cytolytic activity that is CD3 heteroconjugate independent; and (2) introducing the cytolytic lymphocytes into a subject to kill cancer cells.   6757APL.2
