Abstract: A developing device includes a housing in which a circulation path is formed by a first path through which a developer passed to a developing roll flows, a second path disposed offset from the first path in a direction of gravity, a pair of connecting ports connecting the first path and the second path, and a transport member that operates in the housing. The transport member transports the developer in a determined direction, or a reverse direction to the determined direction, in the circulation path according to a load applied for driving the transport member.

Abstract: A lens control device incorporated in a lens device 10A is equipped with a first zoom position sending unit for sending a zoom position signal indicating a zoom position of the first lens device 10A to a lens device 10B; a second zoom position sending unit for sending an adjusted zoom position signal for zoom position adjustment of the lens device 10B to the lens device 10B; a zoom storage unit for storing zoom adjustment information in which a zoom position adjustment amount indicated by the adjusted zoom position signal is correlated with the zoom position of the lens device 10A; and a third zoom position sending unit for sending a zoom position signal for the lens device 10B on the basis of the zoom adjustment information in response to a zoom manipulation signal indicating a zoom manipulation on the lens device 10A.

Abstract: Collision of communication data on a network line is prevented. A plurality of CPU boards which are independent of one another and have respective ones of CPUs mounted thereon are connected by a network line. Since data collision will occur when multiple streams of control data are transmitted on the network line, the order of priority of camera control is decided. If a zoom lens is shifted toward telephoto and, moreover, the aperture of an iris is shifted toward the open side, the order of priority of focusing lens control is raised. If a zoom lens is shifted toward wide angle and, moreover, the aperture of the iris is shifted toward the closed side, the order of priority of focusing lens control is lowered. Since camera control is carried out in accordance with the order of priority, collision of data on the network line is avoided.

Abstract: A lens control apparatus for controlling a lens apparatus having an extender is provided. When an operation of storing a shot is performed in a shot box connected to the lens apparatus having an extender, a memory stores data including a position of a zoom lens group at that time, a position of a focus lens group at that time, and a magnification of the extender at that time. When an operation of reproducing the shot is performed, a CPU transmits a control signal for moving the zoom lens group and the focus lens group to positions represented by the shot. In addition, the CPU transmits to the lens apparatus a control signal for setting the magnification of the extender at a value of the magnification thereof represented by the stored shot.

Abstract: A field frame and a mouse pointer are displayed on a display of a personal computer. The mouse pointer is moved in the field frame by means of a mouse in order to output movement commands in accordance with a vector starting at the center of the field frame and ending at the mouse pointer. Thus, the moving direction and speed of an object of control can be designated only by moving the mouse pointer in the field frame.

Abstract: In a vector control method and system for an induction motor, the decoupling calculation and 2-3 phase transformation are combined to simplify the system configuration, and the plus and minus signs of trigonometric signals are changed according to the rotational direction to enable four-quadrant operation. Further, in the case of a 3-phase induction motor driven by a PWM inverter, the number of the triangular (carrier) wave signals generated during one period of the power supply signal is increased with decreasing frequency of the supply voltage signal to improve the response characteristics when the motor is rotating at a low speed. Furthermore, an initial supply voltage signal with a predetermined frequency is applied to the triangular wave signal generator, when the motor stops, to generate an initial secondary magnetic flux before starting the motor.
