摘要:
A lens driving unit includes a lens holder accommodating a lens or a group of lenses. A coil is disposed on a surface of the lens holder. The lens driving unit is provided with a magnet disposed at a position spaced from the coil by a predetermined distance to move the lens holder along an optical axis according to current flowing in the coil. The lens driving unit is further provided with a guide member guiding movement of the lens holder along the optical axis. Further, a magnetic member is disposed at the lens holder to fix a position of the lens holder by magnetic attraction force exerted by the magnet when no current flows in the coil. The lens driving unit can achieve downsizing, improved resistance to impact, stabilized lens attitude, and reduced power consumption when an auto-focus function is performed.

摘要:
An image entering from the left side of the figure passes through a correcting lens unit, and forms an image on an image pickup device on the right side of the figure. The correcting lens unit includes a cylindrical outer frame and a lens arranged therein, and at coupling points, coupled to one end of each of electrostrictive coils and suspended thereby. Electrostrictive coils strain in response to voltages applied from a voltage applying unit, causing displacement of electrostrictive coils. The displacement is transmitted to correcting lens unit through the coupling points, and therefore, in accordance with the displacement from electrostrictive coils, position and/or direction of correcting lens unit changes.

摘要:
The method of manufacturing toner for electrophotography includes the steps of dissolving or dispersing a toner composition containing a resin and a coloring agent into polymerizable monomers to provide a solution or a dispersed system, emulsifying the solution or the dispersed system with a first surface active agent in an aqueous medium to provide an emulsion, and polymerizing the polymerizable monomers in the emulsion to obtain toner. A second surface active agent having polarity opposite to polarity of the first surface active agent is added after the emulsifying step.

An image-fixing method contains: passing a recording medium bearing an image through a nip between two or more fixing members to fix the image onto the recording medium; and ejecting the recording medium along with the fixing member contacting with a non-image-bearing surface of the recording medium, wherein the fixing member contacting with an image-bearing surface of the recording medium has a lower surface hardness than that of the fixing member contacting with the non-image-bearing surface, the image is comprised of a toner containing toner particles, each toner particle contains wax having an aliphatic hydrocarbon chain, and polyester resin having an aromatic ring, a total amount of the wax in the toner particle is 1 to 20 mass %, determined by DSC, an amount of the wax located in the specific region of the toner particle is 0.05 to 0.40 that is an intensity ratio (P2850/P828) determined by FTIR-ATR, and the wax is partially or entirely encapsulated in the toner particle as dispersed particles.
摘要:
A rotational phase difference detecting system, a method that is capable of very accurately detecting a rotational phase difference between a plurality of rotating bodies, a machine operating-state monitoring system, and a method employing the rotational phase difference detecting system. The detecting system has a first rotating body with a first mark, a second rotating body with a second mark, a mark sensor for detecting the first mark, a first camera for imaging the second mark when the mark sensor detects the first mark, and a display section for displaying the second mark imaged by the first camera. The rotational phase difference is detected from a position of an image of the second mark displayed on the display section and is thus detected very accurately with a simple construction comprising the mark sensor, the first camera, and the display section.

Picture processing apparatus has a pixel judgment circuit and a pixel correction circuit. The pixel judgment circuit includes a target pixel detection circuit for detecting a target pixel having a peak level from the input picture signal, and an edge detection circuit for detecting edges, each present at a distance of n pixels (n≧1) preceding and succeeding the target pixel. Further, the pixel correction circuit has a correction coefficient selection circuit, wherein a peak level correction coefficient is selected according to an output from the target pixel detection circuit, and an edge correction coefficient is selected according to an edge detection output. With the picture processing apparatus, a level of the target pixel is corrected and an edge of the input picture signal is corrected with the pixels of the input picture signal being corrected according to the peak level correction coefficient and the edge correction coefficient.
