    摘要： An annular motor core has a plurality of split core pieces, each of which includes a yoke portion and a tooth. The split core pieces are circumferentially located and arranged in an annular shape such that the yoke portions of the core pieces form an annular shape as a whole and that the distal ends of the teeth of the core pieces face inward or outward each in a radial direction of the core. The core further includes an annular holder, which has joint portions at a plurality of positions in a circumferential direction of the holder. A first end of each of the core pieces is pivotably joined to the corresponding one of the joint portions. Each core piece can be pivoted about the corresponding joint portion relative to the holder such that a second end of the core piece moves in a radial direction of the holder.

    摘要： An optical lens which can be produced by injection molding on an industrial scale, and which has a high refractive index, a low Abbe's number, a low birefringence index, a high transparency and a high glass transition temperature. The optical lens can be produced by injection molding of a polycarbonate resin (preferably having a reduced viscosity of 0.2 dl/g or higher and a glass transition temperature of 120 to 160° C.), wherein the polycarbonate resin is produced by reacting a diol component comprising 99 to 51 mol % of 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene and 1 to 49 mol % of bisphenol A with a carbonate diester. It becomes possible to produce an optical lens preferably having a refractive index of 1.60 to 1.65, an Abbe's number of 30 or smaller, a birefringence index of 300 nm or lower and an all light transmittance of 85.0% or higher.

    摘要： A diaphragm control apparatus in a camera body includes a stepping motor; a lead screw thereof, wherein a slider is driven by the lead screw; a position detector; and a controller. When driving the stepping motor by a predetermined number of steps in a direction to move the slider away from an origin position, the controller detects the slider position before driving the stepping motor stepwise as the origin position via the position detector, and thereafter detects a stepping position of the slider to compare the stepping position with the origin position each time the stepping motor is driven by one step, and counts the number of steps based from the moment at which the stepping position of the slider exceeds a predetermined position in the direction to move the slider away from the origin position against the biasing force of the resilient biaser.

    摘要： A diaphragm control apparatus in a camera body includes a stepping motor, a lead screw thereof, wherein a slider is driven by the lead screw, a position detector, and a controller. When the stepping motor is in a free state, the slider allows a diaphragm operatively-associated rod to move to an initial position. The controller detects the slider origin position when the stepping motor is in the free state and drives the stepping motor stepwise to move the slider away from the origin position against a biasing force of a resilient biaser, and drives the stepping motor stepwise to move the slider toward the origin position while detecting the slider position; and sets an initial excitation pattern of the stepping motor upon a distance from the detected slider position to the origin position becoming less than a slider moving distance for one step of the stepping motor.
