  • Publication number: 20130034930
    Abstract: In an apparatus for manufacturing a dye-sensitized solar cell, a photosensitization dye solution makes contact with an electrode material layer that functions as a working electrode of a dye-sensitized solar cell so that the photosensitizing dye is adsorbed on the layer. Such an apparatus for manufacturing a dye-sensitized solar cell has a substrate housing section to house a substrate with the electrode material layer formed on its surface, and a circulation mechanism to circulate the photosensitization dye solution in such a way that the solution passes a surface of the substrate housed in the substrate housing section. In such an apparatus, a cross-sectional area of a flow path for the photosensitization dye solution in a portion facing the substrate in the substrate housing section is set smaller than a cross-sectional area of a flow path for the photosensitization dye solution in other portions.

  • Patent number: 8084973
    Abstract: A motor driving circuit generates pulse driving signals, and controls the ON/OFF state of a switching circuit connected to a coil of a motor which is to be driven, thereby controlling the conduction period of the motor. A driving signal generating circuit generates the driving signals such that they are pulse modulated according to the torque target value for the motor, and outputs the driving signals to the switching circuit. A current detection circuit detects the current flowing through the coil of the motor. A current limiting circuit controls the logical values of the driving signals generated by the driving signal generating circuit such that the current detected by the current detection circuit does not exceed a predetermined current upper limit. The current limiting circuit increases the current upper limit according to the time elapsed in the starting operation of the motor. After the starting operation of the motor, the current upper limit is set to a predetermined fixed value.

  • Patent number: 7800328
    Abstract: A fan motor driving circuit controls an energized state of a fan motor by performing on and off control of a switching circuit connected to a coil of the fan motor of a driving object. A variable reference voltage circuit generates a voltage whose voltage level changes with time by charging or discharging a capacitor at the start of starting up the fan motor. A drive signal combining unit generates drive signals on the basis of the voltage when at least starting up, and performs on and off control of the switching circuit by the drive signals. An initialization circuit initializes the capacitor before starting up with a transition from off to on of a power supply voltage to be supplied to the fan motor driving circuit as a turning point.

  • Patent number: 7575892
    Abstract: Soyasapogenol B is biosynthesized via two steps of hydroxylation reaction of its precursor ?-amyrin. However, the gene of the hydroxylase concerned in this reaction has not been revealed. Therefore, it was impossible to apply a genetic engineering technique on the hydroxylase. The present inventors reveals that a sequence which corresponds to a soybean-derived cytochrome P-450 gene CYP93E1 encodes an enzyme protein that carries out hydroxylation of the 24-position of an oleanane type triterpene, and also provides a method for applying said gene making use of a genetic engineering technique.
