摘要:
A cleaning device for removing a deposit adhering to an object to be cleaned is disclosed. The cleaning device includes a cleaning chamber forming a space for housing multiple cleaning media shaped like flakes; a circulating air-flow generating unit configured to generate a circulating air flow to cause the cleaning media to fly and repeatedly collide with the object in the cleaning chamber and thereby to remove the deposit adhering to the object; and a cleaning medium recycling unit configured to suction and remove the deposit adhering to the cleaning media that have collided with the object and thereby to recycle the cleaning media. The pencil hardness of the cleaning media is greater than the pencil hardness of the deposit.

A dry type cleaning technology is disclosed. Dust adhering to a cleaning object is removed with a cleaning medium caused to flow by a high-speed airflow. The removed dust is separated from the cleaning medium with a porous member including holes through which air, dust, and granular material can pass but the cleaning medium cannot pass. An area on the porous member where air is received to cause the cleaning medium to flow and an area on the porous member where air is received to suction the dust separated from the cleaning medium are switched.

A telephone terminal executes voice communication with a partner telephone terminal by using a selected codec program to code and decode voice signals. Both telephone terminals have facilities for storing codec programs and transferring codec programs over a communication network. During a voice call, one of the two telephone terminals may transfer a codec program to the other telephone terminal, and the call may then proceed by use of the transferred codec program. This enables voice communication to take place with the best codec program that either telephone terminal can provide, even if the two telephone terminals are associated with different communication systems.

A circulation-air generating unit directly generates circulation air that flows along a surface of a cleaning tank. The circulation air is applied to cleaning medium accumulated on the cleaning tank from a direction orthogonal to a direction of face of the cleaning medium to deliver and flow up the cleaning medium. The cleaning medium is flown up inside the cleaning tank by the force of the circulation air. The cleaning medium flowing inside the cleaning tank collides with a cleaning target object by high-velocity air supplied from a cleaning-medium accelerating unit to remove dust on the cleaning target object.

A fixing device for an image forming apparatus of the present invention includes a rotary body and a pressing member pressed against each other for conveying a recording medium, carrying a non-fixed toner image thereon, while nipping it therebetween. The rotary member includes an under layer and a surface layer formed of resin. The surface layer has two or more phases including a phase strongly adhering to the under layer and another layer contacting the above phase.

In an image blur prevention device for a camera, the limit delay time for image blur reduction is set to be changeable so as to reduce the influences of camera shakes on photographing operations, so as to realize high operability. A shake determining section determines the image blur state on the current image plane on the basis of the camera shake state detected by a shake detecting section. As a result, information corresponding to the level of the current image blur state is sent to an exposure control section. On the basis of image blur state information from the shake determining section when an exposure start instruction signal is received, limit delay time information set in a limit delay time setting section, and the count result obtained by a timer section, the exposure control section determines whether to start an exposure operation in accordance with the state of a release operating section. If it is determined that exposure should be started, a shutter unit is driven by a shutter drive section to perform an exposure operation. If it is determined that exposure should not be started, the shutter drive section is stopped, and no exposure operation is performed.

A shake detecting section for detecting a camera shake, a prevention mode selecting section for selecting a shake prevention mode, and a print area setting portion for setting a print area in a trimming photographic operation are connected to a control section. In addition, a print area display section for displaying the print area set by the print area setting section in the finder of a camera, a focal length information storage section for storing the focal length information of a photographic lens, and a trimming mode selecting section for selecting a trimming mode are connected to the control section. When the trimming mode is selected by the trimming mode selecting section, the hand shake prevention mode is automatically selected, thereby easily preventing a deterioration in image quality due to a hand shake.

There is provided a correcting coil of a deflection yoke wherein a correcting coil is brought into close and wide contact with a neck portion of a bobbin 1 of the deflection yoke by slightly altering the correcting coil which is used at present to further improve magnetic permeability and hence the amount of correction of magnetic lines of force. Correcting coil 11A of the deflection yoke includes a hollow correcting coil bobbin 13 on the outer periphery of which a coil 12 is wound and a core 14 configured into a U-shape by superimposing respective ends of two L-shaped core members made by laminating thin magnetic pieces 15 inside the correcting coil bobbin. A magnetic correcting piece 16 is provided which has a wider area and which makes contact with a neck portion 3 of the bobbin 1 of the deflection yoke 10 on the tip end of each leg part of said U-shaped core 14.
