  • Publication number: 20230305428
    Abstract: An image forming apparatus includes an image bearing member and a developer bearing member. A first period is from when rotational drive of the developer bearing member is started until increased to a speed at which the image forming apparatus performs image forming. A first absolute value of a difference between a developer bearing member surface potential Vdc and an image bearing member surface potential Vd, as determined when the image bearing member is facing the developer bearing member, is obtained during the first period. The value |Vdc?Vd| obtained during the first period is smaller than the value |Vdc?Vd| obtained after the first period. During the first period, the image bearing member surface potential Vd at the facing position is a first potential and, after the first period, the image bearing member surface potential Vd at the facing position becomes a second potential different from the first potential.

  • Patent number: 9996152
    Abstract: In an interface apparatus for presenting a force sense at a remote place or in a virtual space to a user, the number of motors for exerting force upon fingers of the user is decreased. The interface apparatus includes a first arm and a second arm for being attached to the thumb and a finger other than the thumb, respectively. A motor includes a motor main body supported for rotation, and a rotary shaft that relatively rotates with respect to the motor main body. The rotary shaft is connected to the second arm. The motor main body is connected to the first arm so as to impart rotation thereof to the first arm.

  • Patent number: 8569635
    Abstract: A weight sensor includes a deformable body, a first strain resistor provided on an outer side surface of the deformable body, and a pressing member applying a load to the deformable body. The deformable body includes a tubular portion having a tubular shape extending along a center axis and surrounding the center axis, and a projection projecting from an inner surface of the tubular portion. The pressing member moves along the center axis so as to apply a moment to the tubular portion. The resistances of the strain resistors change greatly, allowing the weight sensor to measure a load with high sensitivity.

  • Patent number: 8263031
    Abstract: A method is provided for purifying exhaust gas from an engine having an exhaust passage with a selective reducing catalyst and an oxidation catalyst upstream of the selective reducing catalyst. The method calculates an amount of NOx that flows into the selective reducing catalyst; sets an amount of an additive agent to be supplied to the selective reducing catalyst based on the calculated amount of NOx; determines a degradation degree of the oxidation catalyst; determines whether a correction to the amount of the additive agent is necessary based on the determined degradation degree of the oxidation catalyst; corrects the amount of the additive agent to be supplied when the correction is necessary; and supplies the additive agent to the selective reducing catalyst in the corrected amount if the amount is determined to be corrected and in the uncorrected amount if the amount is determined not to be corrected.
