20090146721 | OOB (OUT OF BAND) DETECTION CIRCUIT AND SERIAL ATA SYSTEM - The present invention provides an OOB detection circuit capable of making accurate signal determination even in the case where a characteristic fluctuation occurs in an analog circuit, thereby preventing deterioration in the yield of a product. To an amplitude determining circuit, a characteristic adjustment register for changing setting of an amplitude threshold adjustment mechanism for distinguishing a burst and a squelch from each other provided for the amplitude determining circuit is coupled. The characteristic adjustment register is controlled by a self determination circuit. An output of the amplitude determination circuit is supplied to a time determining circuit and also to the self determination circuit. On the basis of the output of the amplitude determining circuit, the self determination circuit controls the characteristic adjustment register. | 06-11-2009 |

20140340145 | SIGNAL PROCESSING CIRCUIT, RESOLVER DIGITAL CONVERTER, AND MULTIPATH NESTED MIRROR AMPLIFIER - A signal processing circuit includes a chopper amplifier that has a differential amplifier circuit that amplifies differential input signals Vsp(t) and Vsm(t), and an adder circuit that generates an addition signal Vfil(t) by addition of the chopper output signal Vsub(t) that the chopper amplifier generates. Differential signals inputted into the differential amplifier circuit are interchanged for every first phase period and second phase period, and the adder circuit generates the addition signal by addition of the chopper output signal in the first phase period and in the second phase period. | 11-20-2014 |

20080226674 | Composition Having Antitumor Effect - The present invention is intended to provide a pharmaceutical composition for delivering a chemotherapeutic, preferably an anticancer drug, into cells or into a living organism, using a viral envelope vector, and provides a pharmaceutical composition comprising a chemotherapeutic encapsulated in, or used in combination with, a viral envelope vector having an adjuvanticity as an active ingredient. Thereby it is possible to introduce an anticancer drug encapsulated in a viral envelope vector directly into a tumor, with coadministration of another anticancer drug so as to induce tumor cell-specific antitumor immunity also thanks to the adjuvant action of HVJ-E, and hence to regress the tumor. The present invention also provides a pharmaceutical composition comprising a viral envelope vector and a chemotherapeutic as active ingredients. | 09-18-2008 |
