  • Patent number: 8367044
    Abstract: The present invention provides a sunscreen cosmetic comprising, relative to the total amount of the sunscreen cosmetic, 10-90 wt % of agar microgel (wherein the agar content in the agar microgel is 0.4-1 wt %) and 0.1-5 wt % of a water soluble ultraviolet absorbent. It was necessary to blend in an organic ultraviolet absorbent and such to give sunscreen cosmetics a high SPF value. However, there was a problem in that it was hard for a water soluble ultraviolet absorbent in the formulation to achieve the expected SPF function. Also, sunscreen cosmetics are particularly desired to give a freshing texture upon use. In view of the fact that a high blend ratio of an oil soluble ultraviolet absorbent inhibits the freshing texture upon use, the object of the present invention is to provide a sunscreen cosmetic that achieves a high SPF value and a freshing texture upon use by mainly blending in a water soluble ultraviolet absorbent.

  • Patent number: 8150284
    Abstract: An image forming apparatus is provided that reduces the occurrence of downtime in the case in which the interval between sheets needs to be expanded, and also suppresses the degradation of a photosensitive drum and a developing roller, when continuously forming images. The image forming apparatus of the present invention predicts the start timing of image formation onto the next printing material, and performs control of the positional relationship between the photosensitive drum and the developing roller without decreasing productivity, based on a result of the prediction. Further, the image forming apparatus performs control of the rotating operation of the photosensitive drum, based on the above prediction result.

  • Patent number: 8093843
    Abstract: By the vehicle controller of the present invention, when the economy mode is selected by a driver, boosting by a converter is limited and output torque of a motor is limited. Even in the economy mode, however, if the driver requests large torque, either the limit on boosting or the limit on output torque is cancelled. As a result, a vehicle controller for a vehicle including a battery, a converter boosting/lowering the battery voltage and a motor operating with the power from the converter is provided, by which unnecessary power consumption is reduced and the torque requested by the driver can be generated.
