Patent number: 9588015Abstract: 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.Type: GrantFiled: February 21, 2011Date of Patent: March 7, 2017Assignee: ASAHI KASEI ENGINEERING CORPORATIONInventors: Takashi Sako, Kouichi Tamura

Patent number: 9032267Abstract: 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.Type: GrantFiled: April 15, 2013Date of Patent: May 12, 2015Assignee: NEC CorporationInventors: Noriyuki Shimanuki, Kouichi Tamura, Toshimichi Yokote

Patent number: 8539298Abstract: 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.Type: GrantFiled: July 1, 2008Date of Patent: September 17, 2013Assignee: NEC CorporationInventors: Noriyuki Shimanuki, Kouichi Tamura, Toshimichi Yokote

Patent number: 8215431Abstract: 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.Type: GrantFiled: January 22, 2010Date of Patent: July 10, 2012Assignee: Suzuki Motor CorporationInventor: Kouichi Tamura
