Provided is a multilayer printed board 10 having three single-sided conductor pattern films 16 each having a conductor pattern 13 formed on one surface of a resin film 12 having a through hole 11 and a filled through hole 15 that is the through hole 11 filled with a conductor 14 integrally with the conductor pattern 13. These single-sided conductor pattern films 16 are stacked in such a manner that their tops are oriented in the same way. The conductor patterns 13 of the single-sided conductor pattern films 16 are electrically connected via the filled through holes 15. As the conductor patterns 13 of the single-sided conductor pattern films 16 are interlayer connected via the filled through holes 15, the interlayer connection reliability can be enhanced.

Provided are an improved double-stranded nucleic acid molecule involved in gene expression control mediated by a gene silencing mechanism, a method of producing the molecule, and a pharmaceutical composition comprising the double-stranded nucleic acid molecule. The double-stranded nucleic acid molecule for gene expression control comprises an antisense strand having a length of 18 to 28 nucleotides and a sense strand including a complementary moiety composed of a sequence sufficiently complementary to the antisense strand and a protruding single-stranded 5′-end moiety having a length of 2 to 100 nucleotides. The sense strand and the antisense strand form base pairs via the complementary moiety. The method produces such a double-stranded nucleic acid molecule, and the pharmaceutical composition contains such a double-stranded nucleic acid molecule as an active ingredient.

摘要:
A moving obstacle detection system using a Doppler radar device for an automotive vehicle which detects and informs a vehicle driver that another vehicle (moving obstacle) approaches or moves away from the detecting vehicle, wherein there is provided a means for determining whether the rate of change of the period of a Doppler signal outputted from the Doppler radar equipment with respect to time exceeds a predetermined value so that an erroneous alarm in response to a pedestrian or another vehicle traversing the front detection area of the vehicle, e.g., when vehicle is at rest at in an intersection is inhibited. Consequently, more reliable detection of approach or departure of another vehicle can be achieved.
