20100244960 | DIFFERENTIAL AMPLIFIER CIRCUIT - A differential amplifier circuit includes a plurality of differential-pair transistors, a plurality of current addition transistors, a latch, and a control transistor. The differential-pair transistors have gate electrodes that receive differential input signals respectively. Different potentials of the differential input signals represent a piece of information. The current addition transistors are connected in parallel to the differential-pair transistors, respectively. The latch has differential outputs corresponding to the differential input signals respectively and related to the amplified data. The control transistor receives an activation initiation signal. The current addition transistors are transitioned into electrically conductive state either in a period of time from initiation of amplification operation of the differential amplifier circuit by transitioning the control transistor into an electrically conductive state to increasing a differential voltage to cause inversion of one of the differential outputs of the latch, or at the same time when the amplification operation is initiated. | 09-30-2010 |

20090290953 | SCREW AND SCREW FASTENING STRUCTURE - There is provided a screw treated by a chemical conversion coating of trivalent chromium having a torque characteristic approximately equivalent to a screw of a hexavalent chromate treatment. For the purpose, on a surface of a bolt, a zinc plating layer is formed by a zinc plating treatment. On the layer, a chemical conversion coating of trivalent chromium is also formed by a treatment of chemical conversion coatings of trivalent chromium. The coating is formed to be thin and soft so that the zinc-based plating layer can be exposed on the surface due to rubbing off of the chemical conversion coating of trivalent chromium at a contact portion to a fastened member of the bolt by tightening the bolt. | 11-26-2009 |
