Abstract: A method of determining the level of the effect of each system entity on the overall system performance, wherein the status of each entity at each one of discrete points of time is determined as the corresponding one of an active and an inactive status; the length of the active period in which each entity is situated without interruption in the active status is determined as an active time; and, on the basis of the relationship in magnitude between the system entities with respect to the determined active time, the level at which each entity affects the performance of the system is determined.

Abstract: The present invention provides a lens barrel apparatus dispensing with deliberate switching between manual and automatic operation modes and permitting quick adjustment of conditions regarding the object. In this apparatus, a gear moving plate of a clutch mechanism is connected to the external gear of a zooming or focusing ring, a gear fixing plate of the clutch mechanism is connected to a zoom motor, and the gear moving plate is operated by a clutch operating motor via a coil spring and a moving gear to connect and disconnect the fixed plate. When the clutch mechanism is disconnected, a movable disk and a coil spring are enabled to freely rotate by a thrust bearing. By operating the clutch mechanism on the basis of an operational control signal for a zooming switch, switching between manual and electric operation modes is automatically accomplished. Further the manual operation torque of the zooming ring can be either adjusted with a volume control device or automatically maintained at a constant level.

Abstract: A method of adding oil and fat to porous feed is disclosed wherein porous feed together with oil and fat are continuously inserted into a partially evacuated chamber of an oil and fat adding apparatus while, simultaneously, porous feed that has remained therein for a specified time is continuously being removed from the chamber.

Abstract: The lens apparatus permits rapid focusing by the operator demanding an autofocus start-up direction to carry out AF in the direction in an AF mode. When a start of the AF mode is instructed, an AF standby state of waiting for the operator to demand the AF start-up direction by operating a focus operation member, thereby permitting the operator to properly demand the AF start-up direction, and permitting the demand to be appropriately detected. When automatically switching from the state where the operator operates the focus operation member to the AF, condition of the switching is that a focus evaluation value exceeds a predetermined threshold based on the operation of the focus operation member, or that an operation amount of the focus operation member is changed more then a predetermined amount, thereby permitting further rapid focusing and improvement of operability.
