| 20080212846 | BIOMETRIC AUTHENTICATION USING BIOLOGIC TEMPLATES - Tools and techniques for biometric authentication obtain a biologic information input such as a fingerprint image, which is to be accepted or rejected as being input from an authentic user. Calculated matching scores show respective degrees of similarity between the biologic information input and several templates. The templates include a fixed registration biologic information template, as well as non-fixed learning biologic information templates which are subject to replacement. | 09-04-2008 |

| 20110210296 | SEMI-CONDUCTIVE RUBBER COMPOSITION AND VULCANIZATE THEREOF - The present invention provides a rubber composition, which realizes low hardness and low compression set while maintaining semi-conductivity, and a vulcanizate thereof. Also the rubber composition can be obtained by blending an epichlorohydrin-based rubber having satisfactory semi-conductivity and an acrylonitrile-butadiene-based rubber as a reactive plasticizer, and also blending zinc oxide, a thiuram-based compound and a quinoxaline-based compound. | 09-01-2011 |

| 20110051013 | FRONT-END CIRCUIT, TUNER, AND TELEVISION BROADCASTING RECEIVER - A front-end circuit according to the present invention includes a VCO which oscillates a local signal, a mixer which converts an RF signal Frf into a baseband signal, a DC offset cancel circuit which detects a DC offset contained in the baseband signal and then eliminates the DC offset, and a local frequency control circuit which controls a frequency of the local signal. In a case where the RF signal is an analog television signal, the local frequency control circuit controls the frequency of the local signal so that a frequency of the baseband signal differs from each frequency spectrum of a luminance signal contained in a video signal which is generated by demodulating the baseband signal. This makes it possible to provide the front-end circuit which can prevent video distortion caused when a frequency spectrum is eliminated from the luminance signal. | 03-03-2011 |

| 20090131209 | ROCKER JOINT PIN TYPE SILENT CHAIN - In a rocker joint silent chain, the link plates have two different engagement pitches, and the connecting pins are composed of combinations of rocker pins and joint pins, where each rocker pin has one of two thicknesses and each joint pin has one of two thicknesses, so that the rocker joint pins of the chain have three different thicknesses. The link plates and connecting pins are arranged randomly along the length of the chain. | 05-21-2009 |
| 20100216580 | SILENT CHAIN - In a silent chain, cushion pads are provided in the inner flank regions of at least every second link row. These cushion pads restrict inward flexion of the chain and reduce vibration of the free span regions of the chain. The cushion pads can be individual pads each associated with a link plate, or elongated pads each associated with a row of link plates. In either case, side parts protruding toward the outside of the loop formed by the chain can also restrict outward flexion of the chain. | 08-26-2010 |

| 20080248908 | Silent chain - In a silent chain comprising interleaved and relatively pivotable rows of link plates, protrusions formed in the link plates contact relatively pivotable link plates in adjacent rows so that the area of contact is reduced. The protrusions can be annular, or they can be in the form of arcs that are of a size and position such that the arcuate protrusions of each plate do not interfere with the arcuate protrusions of an adjacent plate as the chain bends during use. The plates can have rectangular protrusions, or arcuate protrusions each consisting of an arc-shaped collection of dot-shaped protrusions. | 10-09-2008 |
| 20080268996 | SILENT CHAIN - In a silent chain, a flank surface which comes into contact with a sprocket tooth at the start of engagement has a partially protruding portion continuously formed along the longitudinal direction of the flank surface. Only the partially protruding portions of link plates that initially contact the sprocket teeth are positively caused to wear during running in of the chain, so that protruding portions of flank surfaces of other link plates that did not initially contact the sprocket teeth are brought into contact with the sprocket teeth. | 10-30-2008 |

| 20090249032 | INFORMATION APPARATUS - An information apparatus comprises: a barrel shifter composed of a bidirectional 1-bit shifter, . . . , and a bidirectional 24-bit shifter which are connected in series; a control unit for outputting an endian conversion control signal SE indicating one of a shift operation and endian conversion; an endian conversion unit for generating data by endian conversion using data obtained by performing a shift operation in the bidirectional 8-bit shifter and the bidirectional 24-bit shifter; and a selector for selecting, when the endian conversion control signal SE indicates a shift operation, data outputted from the bidirectional 24-bit shifter, and selecting, when the endian conversion control signal SE indicates endian conversion, the data outputted from the endian conversion unit. | 10-01-2009 |
