  • Patent number: 8652526
    Abstract: An astrocyte-specific drug carrier containing a retinoid derivative and/or a vitamin A analog as a constituent; a drug delivery method with the use of the same; a drug containing the same; and a therapeutic method with the use of the drug. By binding a drug carrier to a retinoid derivative such as vitamin A or a vitamin A analog or encapsulating the same in the drug carrier, a drug for therapeutic use can be delivered specifically to astrocytes. As a result, an astrocyte-related disease can be efficiently and effectively inhibited or prevented while minimizing side effects. As the drug inhibiting the activity or growth of astrocytes, for example, a siRNA against HSP47 which is a collagen-specific molecule chaperone may be encapsulated in the drug carrier. Thus, the secretion of type I to type IV collagens can be inhibited at the same time and, in its turn, fibrosis can be effectively inhibited.

  • Patent number: 8554403
    Abstract: A vehicle failure is diagnosed based on data recorded in an electronic control unit (ECU) of a vehicle. Driving data pertaining to multiple parameters which are stored in the electronic control unit of the vehicle for when a vehicle failure occurs are compared with reference values representing data during normal driving in order to diagnose a failure. The device utilizes an approximate search between inspection data, that is, driving data which are stored in the electronic control unit of the vehicle to be diagnosed for failure, and reference value groups categorized by driving environment, wherein a normal value range is set for each of the aforementioned parameters categorized by driving environment, and selects the reference value group categorized by driving environment which approximates the inspection data.

  • Patent number: 8482439
    Abstract: A signal corresponding to a short-period change and a signal corresponding to a long-period change of a sound signal are detected, and optimal quantization is performed based on the combination of the two signals. In an ADPCM encoding apparatus (100), a differential value dn between a 16-bit input signal Xn and a decoded signal Yn-1 of one sample ago is calculated by a subtractor (102). Thereafter, the 16-bit differential value dn is adaptively quantized by an adaptive quantizing section (103), so as to be converted to a (1 to 8)-bit length-variable ADPCM value Dn. Thereafter, the ADPCM value Dn is compression-encoded by a compression-encoding section (108) to generate a signal D?n, and the signal D?n is framed by a framing section (130) and outputted. Further, in an ADPCM decoding apparatus, a framed input signal is subjected to a reverse of the aforesaid process so as to be decoded.

  • Patent number: 8409543
    Abstract: A pyrochlore-type oxide represented by a general formula A2B2O7-Z is prepared by precipitate formation, where A and B each represent a metal element, where Z represents a number of at least 0 and at most 1, where A contains at least one element selected from a group consisting of Pb, Sn, and Zn, and where B contains at least one element selected from a group consisting of Ru, W, Mo, Ir, Rh, Mn, Cr, and Re. Impurities are then sufficiently removed through washing and drying processes, and the pyrochlore-type oxide is calcined under controlled conditions. This allows the crystallinity of the pyrochlore-type oxide, which contained amorphous parts immediately after the production of the precipitate, to be increased so that the resistance to acid can be improved while preventing particle aggregation.

  • Patent number: 8301281
    Abstract: A favorable high-frequency signal is generated and practical high-frequency signal interpolation is implemented through simple processing. A digital audio signal reproduced by an instrument, which also carries out compression, is supplied as an original signal to an input terminal 1, and this original signal is then supplied to a digital sample and hold circuit 3 via a band-pass filter 2. The signal from the digital sample and hold circuit 3 is supplied to a ±1 multiplier 6, which then alternately inverts sign bits. The harmonic components of this signal in which the sign bits are inverted alternately are extracted by a high-pass filter (HPF) 7. Meanwhile, the original signal from the input terminal 1 is supplied to a delay circuit 8 equivalent to the processing time consumed by the aforementioned digital sample and hold circuit 3 and related circuits, forming an adjusted, delayed signal.

  • Patent number: 8274511
    Abstract: The present invention provides an apparatus which displays a plan wiring diagram and three-dimensional layout diagram by associating them with each other so that they can be viewed easily. A apparatus for displaying wiring includes a first storage for storing an image of a plan wiring diagram which shows parts and wirings and a second storage for storing a three-dimensional layout of an apparatus which incorporates the parts and the wirings, and a third storage for storing intermediate images transitional between a starting image in the plan wiring diagram and an ending image of a shape of the corresponding wiring in the three-dimensional layout. A processor displays the plan wiring diagram on the display device by retrieving the plan wiring diagram from the first storage based on a user's selection, and retrieves the intermediate images of a wiring from the third storage when the wiring is selected from the plan wiring diagram and displays transitions to the shape shown in the three-dimensional layout.
