Filed: 1997-12-04
Abstract: A signal disconnection detection circuit has a first comparing unit for producing a signal disconnection recognition signal only when a level of the first input signal is smaller than a first threshold value; a second comparing unit for producing an incomming signal only when a level of a second input signal is larger than a second threshold value; and a counter that receives the outputs of the first and second comparing unit and starts counting up when the first comparing unit produces the signal disconnection recognition signal, determining the possibility of the signal disconnection.  The counter resets the counted value and stops its operation, determining that a reception signal is not disconnected, when the second comparing unit produces the reception signal.  The counter produces the signal disconnection detection signal, determining that the signal is actually disconnected, when the second comparing unit produces no incomming signal before completion of the counting up.

Title: Gas-turbine engine
Inventor: ENDOU TSUNEO
IPC: F23R3/44
Filed: 1996-08-02
Abstract: A gas turbine engine E includes a compressor wheel 9 and a turbine wheel 10 fixed to a rotary shaft 8, a can-type combustor 18 disposed on an extension of the axis L of the rotary shaft 8, and a circular plate-type heat exchanger 12 disposed to surround a radially outer portion of the can-type combustor 18. The compressor wheel 9, the turbine wheel 10, the can-type combustor 18 and the plate-type heat exchanger 12 are disposed coaxially with the axis L of the rotary shaft 8.      Therefore, the flows of compressed air and combustion gas are symmetrized with respect to the axis L, and the distribution of temperature within a casing is also symmetrized with respect to the axis L. Thus, the flows of compressed air and combustion gas within the gas turbine engine E can be axially symmetrized, and the generation of a thermal distortion can be prevented.

Patent CA-2230065-A1 (CA)
Inventor: CANDELORE BRANT
IPC: H01L23/58
Filed: 1998-02-20
Abstract: An anti-tamper shield for an integrated circuit (IC) includes a bond wire which passes through a protective layer such as an epoxy encapsulating layer of the IC. The bond wire carries a signal, such as a steady state current, which allows an active component of the IC, such as a secure processor, to function. The bond wire is carried within and/or proximate to the encapsulating layer such that a decapsulation of the IC will cause a rupture of the electrically conductive member, thereby rendering the processor non-functional. The bond wire may be coupled to the processor in a variety of configurations, including the use of internal or external bond pads, lead frame contacts, and/or directly to a computer board on which the IC is carried. A metallic shield layer may be located between the active component and a top portion, of the encapsulating layer to prevent a pirate from using an electron, microscope, for example, to survey the active component region.

Title: Method and apparatus for measurement of absolute biaxial birefringence in monolayer and multilayer films, sheets and shapes
Inventor: AJJI ABDELLAH
IPC: G01J4/04
Filed: 1999-02-11
Abstract: A system and apparatus for the measurement of absolute biaxial birefringence of plastic materials is described. The materials which must be at least partially transparent can be constituted of one or several similar or dissimilar layers.  In the latter case, the birefringence of each material can be determined. The technique uses a multiwavelength white light source that provides at least two beams projected at different angles of incidence on the sample. The beams pass through first polarizers before they are incident on the sample and through second polarizers after they have passed through the sample. The beams are then directed to a detector for measuring each beam intensity or transmittance as a function of wavelength for the incident angles at different times, and are analyzed using nonlinear regressions to determine retardation. By the knowledge of the thickness of the material, the absolute biaxial birefringences are calculated for any specific wavelength. The regression procedure incorporates the material dependent optical constants for the calculations and to discriminate between different materials for multilayer samples.
