  • Patent number: 9588015
    Abstract: A sign of a minor rubbing abnormality of a slide bearing in a diesel engine is accurately detected. In order to realize the accurate detection, the following is performed: detecting waveform data which represents an acceleration of a vibration which occurs when a slide bearing is in operation; transforming acceleration waveform data into an acceleration spectrum of a frequency domain by applying a Fourier transform to the acceleration waveform data; quantifying a plurality of peak information which occurs at a rotational frequency interval of a shaft to be measured in the acceleration spectrum by performing a predetermined signal process combined with rotational frequency information of the shaft; obtaining a characteristic value; monitoring whether the obtained characteristic value has exceeded a predetermined threshold value; and when the characteristic value has exceeded the threshold value, determining that an abnormality has occurred in the slide bearing.

  • Patent number: 9032267
    Abstract: A transmitting unit divides a transmit data into a plurality of code blocks, and encodes each of the plurality of code blocks to generate a transmission signal. The transmitting unit transmits the transmission signal, and a receiving unit receives the transmission signal as a reception signal. The receiving unit, when being an error in the reception signal, transmits a retransmission request feedback data which contains a NACK data and a data indicating the first code block group to the transmitting unit. First resources are assigned for each of the plurality of code blocks of the transmission signal. The transmitting unit assigns resources of the first code block group of the plurality of code blocks of the transmission signal to second resources which are fewer than the first resources, based on the retransmission request feedback data, and retransmits the transmission signal to the receiving unit.

  • Patent number: 8539298
    Abstract: A transmitting unit divides a transmit data into a plurality of code blocks, and encodes each of the plurality of code blocks to generate a transmission signal. The transmitting unit transmits the transmission signal, and a receiving unit receives the transmission signal as a reception signal. The receiving unit receives performs an iterative decoding to each of the plurality of code blocks of the reception signal. The iterative decoding is terminated to a first code block group in which an error has not been detected before a first setting iteration count. The receiving unit, when being an error in the reception signal, transmits a retransmission request feedback data which contains a NACK data and a data indicating the first code block group to the transmitting unit. First resources are assigned for each of the plurality of code blocks of the transmission signal.

  • Patent number: 8215431
    Abstract: A small vehicle mounted with a fuel battery employs a fan that outputs a satisfactory amount of air with small power consumption. An exhaust duct reduces pressure loss and airflow resistance. Hydrogen purged from the fuel battery is discharged out of the vehicle along with water through the exhaust duct. A fan box has a fan for introducing air into the fuel battery mounted on a frame constituting vehicle body. After cooling the fuel battery, air is exhausted out of the vehicle. The exhaust duct includes two parts; i.e., a first exhaust duct connected to the rear side of the fan box for introducing the air after cooling of the fuel battery; and a second exhaust duct connected to the rear side of the first exhaust duct for exhausting the air flowing thereinto from the first exhaust duct out of the vehicle body.

  • Publication number: 20100003576
    Abstract: An exhaust apparatus for a fuel cell system includes: a fuel cell for receiving air containing oxygen at a cathode and for receiving a fuel gas containing hydrogen at an anode, and for executing a power generation. An exhaust pipe exhausts air from the cathode side and a purge pipe exhausts fuel gas from the anode side. A manifold confluence connects the exhaust pipe and the purge pipe, while a muffler is arranged on a downstream side of the manifold. An upstream side of the exhaust pipe is supported by a vehicle body floor and a downstream side is supported by a subframe. A confluence connecting portion of the purge pipe exhausts used fuel gas containing hydrogen. The exhaust pipe is disposed generally uniformly along a surface that generally is parallel with the ground.

  • Patent number: 7037892
    Abstract: This invention relates to a hematopoietic stem cell proliferating agent comprising IGF-I, a hematopoietic stem cell proliferating agent comprising IGF-I and at least one protein selected from among SCF, M-CSF, and G-CSF, and a method of growing hematopoietic stem cells which comprises culturing hematopoietic stem cells in a medium containing IGF-I and at least one protein selected from the group consisting of SCF and M-CSF. The hematopoietic stem cell proliferating agent of the invention causes hematopoietic stem cells to proliferate in the undifferentiated state whether in vivo or in vitro and can, therefore, be used for amelioration of the cytopenia induced by radiotherapy or chemotherapy using anticancer drugs, prevention of infectious diseases associated with lymphopenia, or in vitro culture for multiplication of hematopoietic stem cells and extrasomatic culture of recombinant stem cells in gene therapy.
