  • Publication number: 20140186836
    Abstract: Provided are a diagnosis marker, a diagnosis method, and a therapeutic agent suitable for diagnosing and treating amyotrophic lateral sclerosis (ALS). Also provided are an animal model and a cell model suitable for developing a therapeutic agent and a treatment method for ALS. The diagnosis method for ALS includes: an isolation step in which a nucleic acid is isolated from a specimen taken from a subject; a detection step in which bases expressed in a human chromosome 10 optineurin (OPTN) gene region are detected from the isolated nucleic acid; and a determination step in which it is determined whether or not the detected bases are mutated.

  • Publication number: 20140029661
    Abstract: The present technique relates to a reception device and a reception method which can improve equalization performance. An equalization processing unit has a time domain equalization unit which equalizes a received signal in a time domain and a frequency domain equalization unit which is provided in parallel to the time domain equalization unit and which equalizes the received signal in a frequency domain, and performs control of switching between the time domain equalization unit and the frequency domain equalization unit. The present technique can be applied to, for example, equalize a signal of data transmitted by way of single carrier transmission or data transmitted by way of multicarrier transmission.

  • Patent number: 8576902
    Abstract: The present disclosure provides a receiving device including, a receiver configured to receive a signal that is transmitted via a propagation path and is modulated by a predetermined system prescribed by a predetermined standard, a demodulator configured to demodulate a received signal, an estimator configured to estimate a signal-to-noise ratio relating to the propagation path, obtained from a data signal included in the demodulated received signal, and a corrector configured to correct an estimated signal-to-noise ratio in accordance with a transmission parameter obtained from the received signal.

  • Patent number: 8576950
    Abstract: Disclosed herein is a reception apparatus including: a reception section configured to receive a signal modulated by a predetermined system defined by a predetermined standard; a decoding section configured to decode transmission parameters included in the received signal; an acquisition section configured to acquire from among sequentially decoded transmission parameters the parameters used in a demodulation process performed on the received signal; and a control section configured such that if the acquired transmission parameters used in the demodulation process on the received signal are different from the sequentially decoded transmission parameters, then the control section controls the demodulation process on the received signal based on newly decoded transmission parameters.

  • Patent number: 7247114
    Abstract: A forward/reverse change-over mechanism (3) of an automatic transmission comprises a forward clutch (5) inside a drum (7) with the base (7c) which rotates together with an input shaft (1). The forward clutch (5) engages by driving a piston (9) housed in the drum (7) by the oil pressure of an oil chamber (10) between a base (7c) and the piston (9). Projecting bearings (16) which seat the piston (9) are formed by press-forming at equal angular intervals concentrically with the axial center of the drum (7) in the base (7c). By installing a sensor body (18) which responds to the passage of depressions (17) formed underneath the bearings (16), the forward/reverse change-over mechanism (3) can be made compact and manufactured with a small number of parts and machining steps.
