An object of the present invention is to remove or reduce iodine contained in a marine natural product extract, while maintaining the original flavor, taste, appearance, etc. of the marine natural product extract before processing. A first anion exchange membrane () and a second anion exchange membrane () are sequentially arranged from the anode () side. Between the anion exchange membranes (), an extract receiving compartment () is formed and fed with a marine natural product extract (). An iodine recovery compartment () is formed on the anode side of the first anion exchange membrane (). A replenisher receiving compartment () is formed on the cathode side of the second anion exchange membrane () and fed with a replenisher containing chlorine ions (). During electrodialysis, the iodine ions contained in the marine natural product extract () pass through the first anion exchange membrane () and migrate into the iodine recovery compartment (), while the chlorine ions contained in the replenisher () pass through the second anion exchange membrane () and replenish the extract receiving compartment ().

A lens device is used with an imaging device having a imaging-lens and an aperture stop device. The lens device includes a lens barrel that houses the imaging-lens and the aperture stop device, a first operation ring that is on an outer circumferential portion of the lens barrel and that is rotatable in a circumferential direction of the outer circumferential portion about an axis line of the lens barrel in order to adjust the aperture-area of the aperture stop device, and a second operation ring that is parallel with the first operation ring and is rotatable in the circumferential direction of the outer circumferential portion about the axis line of the lens barrel in order to adjust a transmittance of a variable light transmission filter.

Lens device and imaging device mounted with the lens device

An outer tube body of a device for changing operating force is connected to a gear part of a zoom ring of a lens barrel to rotate the outer tube body together with the zoom ring. The outer tube body has a cylindrical shape and includes a hollow part into which an inner tube body whose rotation is restricted is arranged. Grease is interposed in a gap is formed between an inner peripheral surface of the outer tube body and an outer peripheral surface of the inner tube body. A load caused by viscosity resistance of the grease is applied against rotation of the outer tube body together with the zoom ring. The inner tube body can be displaced in a direction of the center axis so that area of a sliding contact region between the outer tube body and the inner tube body is changed.

Device for changing operating force of lens device

A lens device () is provided with a first operating ring () for adjusting the opening surface area of an aperture device () and a second operating ring () for adjusting the transmittance of a variable light transmittance filter (). The correspondence relation between the operational amount for the first operating ring and the rate of change in the amount of light transmitted by the aperture device and correspondence relation between the operational amount for the second operating ring and the rate of change in the amount of light transmitted by the variable light transmittance filter are the same.

A lens device, in which object light is branched by a half mirror after passing through a photographic lens to allow photographing with two photographing means and in which the half mirror can be retracted from the optical axis to obtain a clear image using one of the photographing means, is provided. The half mirror in the lens device is provided between a front-side relay lens and a rear-side relay lens, and is provided such that the half mirror can be retracted away from an optical axis of the photographic lens and advanced toward from the optical axis. The rear-side relay lens is moved along the optical axis to a position in accordance with the retracting of advancing of the half mirror.

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. Gradually switching a clutch, which switches the focus lens driving from manual to electrical operation, from a manual to electrical state in switching to the AF can eliminates uncomfortable operation feeling of the focus operation member. Further, for the processing after completion of focusing by the AF, a mode of returning to the AF standby state of waiting for the operator to demand the AF start-up direction, mode of returning to a manual mode, or mode of continuing the AF can be selected, which permits improvement of convenience of the AF mode.

Lens apparatus

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. Further, if focusing is done when the zoom is set for manual operation, any variation in the angle of field due to a pumping phenomenon is corrected with a correcting circuit.

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. The continuous nature of this method allows porous feed having high fat and oil content to be produced more rapidly than previously possible.

Method of adding fats and oils to porous fodder

A converter unit for a lens unit of a camera, which is able to match optical axes of a plurality of kinds of converter lenses with different magnifications, which are revolvably mounted on a rod, with an optical axis of the lens unit properly. One of the converter lenses is revolvably mounted on the rod by two bearings through a connecting member. One of the bearings is attached on an eccentric external circumference of a collar member attached on the rod. The rotation of the collar member adjusts an eccentric direction of the collar member and the direction of an optical axis of the converter lens.

Converter unit of camera

A small and light TV camera extender switching apparatus which is capable of switching two extenders having different magnifications. A first extender and a second extender are supported by the same support shaft so as to be rotatable independently of each other. The first extender and the second extender are rotated by operating the first operating lever and the second operating lever, respectively, via gear trains, so that either extender is moved from the resting position outside of an imaging optical path to a working position in the imaging optical path. A stopper mechanism which is capable of adjusting a retaining position is disposed on the lens frame or in the case so as to adjust the retaining positions of each extender at the resting position and the working position.
