  • Patent number: 11948958
    Abstract: The solid-state imaging element includes a photoelectric converter, a first separator, and a second separator. The photoelectric converter is configured to perform photoelectric conversion of incident light. The first separator configured to separate the photoelectric converter is formed in a first trench formed from a first surface side. The second separator configured to separate the photoelectric converter is formed in a second trench formed from a second surface side facing a first surface. The present technology is applicable to an individual imaging element mounted on, e.g., a camera and configured to acquire an image of an object.

  • Patent number: 11934087
    Abstract: A projector includes a cooling fan, and a processor, and the processor executes, in a case in which the cooling fan is operating in a first revolution speed mode, a control of switching an operation mode of the cooling fan to a second revolution speed mode whose revolution speed is faster than that of the first revolution speed mode in a case in which an obtained temperature detection value reaches a first threshold, and executes, in a case in which the cooling fan is operating in the second revolution speed mode, a control of switching the operation mode of the cooling fan to a revolution speed mode whose revolution speed is slower than that of the second revolution speed mode in a case in which an obtained temperature detection value decreases below a second threshold which differs from the first threshold.

  • Patent number: 8999599
    Abstract: A method of fabricating a membrane electrode assembly, comprising: obtaining a mixture by mixing and kneading electrically conductive particles, a polymer resin, a surfactant, and a dispersion solvent (S1); obtaining a sheet-like mixture by rolling out and shaping the mixture (S2); obtaining a carbon sheet by heat-treating the sheet-like mixture at a first heat treatment temperature such that the surfactant and the dispersion solvent are removed from the sheet-like mixture (S3); obtaining a dispersion liquid by mixing electrically conductive particles, a polymer resin, a surfactant, and a dispersion solvent (S4); forming, on the carbon sheet, a dispersion liquid layer thinner than the carbon sheet by forming and drying a coating of the dispersion liquid on the carbon sheet (S5); obtaining a gas diffusion layer in which a carbon layer is formed on the carbon sheet, by heat-treating the carbon sheet on which the dispersion liquid layer is formed at a second heat treatment temperature lower than the first heat t

  • Patent number: 6661201
    Abstract: The present invention provides a method for controlling battery charging and discharging in which a battery is charged and discharged such that a SOC (state of charge) value of the battery is increased/decreased to a predetermined range when the SOC value of the battery is in a predetermined range; and a range of the SOC values in which charging and discharging processes are performed sequentially varies and a range of the SOC values after the charging and discharging processes also sequentially varies.

  • Patent number: 6545449
    Abstract: A method for controlling charge preventing an operation of a valve during charging and suppressing the false detection of the upper limit charging voltage due to the memory effect at the charge side in a secondary battery mounted on an automated guided vehicle is presented. The method includes charging the secondary battery at a charging current value of not less than 0.5 C and not more than 4.0 C; detecting current that flows in the secondary battery and calculating the remaining capacity by accumulating at least the detected current; and completing the charge to the secondary battery when the calculated remaining capacity is not less than the threshold value that is pre-set to not less than 60% and not more than 95%.
