  • Patent number: 9147896
    Abstract: A fuel cell system is basically provided with a fuel cell, a pressure adjusting valve, a purge valve and an anode pressure controller. The fuel cell includes an anode that receives an anode gas and a cathode that receives a cathode gas to generate electric power corresponding to a load. The pressure adjusting valve is disposed in a supply path to adjust anode gas pressure to the anode. The purge valve is disposed in a discharging flow path to discharge an anode-off gas containing impurities from the fuel cell. The anode pressure controller is configured to control the pressure adjusting valve to perform a pulsation operation that pulsates the anode gas pressure of the fuel cell. The anode pressure controller decreases a median pressure of the pulsation operation as a wetness level of an electrolyte membrane of the fuel cell stack is determined to become higher.

  • Patent number: 8156363
    Abstract: An information processing device and a mobile terminal include a power consumption calculator which calculates, for each processing executed by the information processing device (or mobile terminal), power consumption information concerning an amount of power consumed by executing each processing. A request generator compares the amount of power indicated by the power consumption information and a remaining amount of power of the information processing device(or mobile terminal), and generates a request to execute predetermined processing according to a result of the comparison. A request processor executes the predetermined processing in response to the generated request.

  • Patent number: 7842854
    Abstract: Identification of a gene from monocotyledonous plants such as rice, which codes for a transcription factor specific to a stress tolerant gene and provision of a novel environmental stress tolerant plant using the gene. From the rice genome, a gene, which binds to a cis element existing upstream of the gene encoding a stress responsive protein and for a transcription factor to activate the transcription of the gene, is identified. Further, the gene of the transcription factor is used to transform a plant, thereby improving tolerance against environmental stresses such as low temperature, dehydration, and salt stresses.

  • Publication number: 20100273708
    Abstract: The present invention provides adiponectin expression-inducing agents, and therapeutic agents using the same for obesity and obesity-related diseases such as cardiovascular diseases or metabolic diseases, as well as methods of searching for adiponectin expression-inducing agents. KLF9, which can bind to the 32-bp fragment of position ?188 to position ?157 from the adiponectin expression start site, was demonstrated to enhance adiponectin promoter activity. Therefore, the present invention uses KLF9 as an adiponectin expression-inducing agent, and suggests that KLF9 replenishment therapy is useful for preventing and/or treating obesity or obesity-related diseases including metabolic diseases such as insulin resistance and type II diabetes, and cardiovascular diseases.
