Title: Developing device and image forming device provided therewith
Inventor: OGAWA KIYONARI
IPC: G03G9/08
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of toner itself and to clean a developer carrier by providing a peeling member with a scraping member for scraping excess developer on the peeling member. SOLUTION: The peeling roller 4 abutting on a developing sleeve 3 is formed by using material such as urethane sponge, etc. The roller 4 is rotated in a reverse direction to the sleeve 3 and peels the toner T on the sleeve 3 which does not contribute to development though it passes a developing area being a position where it is opposed to a drum on the rubbing surfaces of the sleeve 3 and the roller 4, and then cleans the surface part of the sleeve 3. Furthermore, a scraper 5 arranged at the inner part of a container 2 from the roller 4 is arranged on the roller 4. The scraper 5 scrapes the toner T peeled from the sleeve 3 by the roller 4 and adhering to the roller 4 nearly 100%.

Title: Zoom lens
Inventor: HORIUCHI AKINAGA
IPC: G02B15/17
Filed: 1986-01-28
Abstract: PURPOSE:To obtain a small-sized and light in weight zoom lens having a high performance and a high magnification, by containing an iris diaphragm in the fourth lens group, and using a refractive index distribution type lens consisting of a heterogeneous medium, for at least one lens being adjacent to the iris diaphragm. CONSTITUTION:At least one piece of refractive index distribution type lens of a co-axial system is used for the fourth lens group. The figure shows an optical system which uses one piece of refractive index distribution lens instead of three pieces of the front group, and the lens has a distribution in which a refractive index decreases gradually in the direction orthogonal to the optical axis. When it is tried to constitute a correction of a spherical aberration, an axial chromatic aberration and a comatic aberration of the periphery of the both faces, by one piece of homogeneous lens, the Petzval sum is generated greatly by a negative value from a zoom part, therefore, it is necessary to use a nitric material of a low refractive index, but when the refractive index distribution type lens is used, the Petzval sum and a spherical aberration can be corrected satisfactorily. Also, as for the lens, not only the number of pieces can be curtailed, but also the optical overall length can be shortened.

Title: Photographic film density reader
Inventor: ISHIKAWA KEN
IPC: G01N21/59
Filed: 1983-02-03
Abstract: PURPOSE:To read the density of each part of a film at a high speed, and to simplify a film device by using a mirror whose reflection angle is varied at a high speed and an Ftheta lens, and scanning a measuring luminous flux by one straight line on a plane of a film to be measured.

Title: Visual inspection of welded part
Inventor: SHIRASAWA MITSURU
IPC: G01N21/88
Filed: 1994-02-10
Abstract: PURPOSE:To collectively judge of whether or not a welded part is good on the basis of an image, by detecting the presence/absence of a welded part and detecting the position and a welding strength. CONSTITUTION:Density of each pixel of an image taken by an image input device 1 is A/D converted 2 and processed in a pretreatment part 3. In other words, a differential image (in a differential direction) is formed on the basis of an original image which has a differential value corresponding to a changing ratio (changing direction) of density of a pixel to that of an adjacent pixel as the value of the pixel. Pixels having larger differential values than those of surrounding pixels are coupled to extract edges of a width of one pixel to obtain an edge image. The obtained images are stored in memories 4-7 respectively for the original image, differential image, differential direction image and edge image. An operating/processing part 8 detects, on the basis of the images, the presence/absence of a welded part, the presence/absence of the welded part at a predetermined position of a to-be-inspected object, and a welding strength from the gloss of the part. Accordingly, an inspection for parts other than the welded part is avoided, and whether or not the position and strength of the welded part are good can be judged.

Title: Magnetic recording/reproducing apparatus
Inventor: SHIMAZAKI TOMOAKI
IPC: G11B5/588
Filed: 1993-02-04
Abstract: PURPOSE:To obtain a magnetic recording/reproducing apparatus which enhances the tracking sensitivity in the vicinity of the optimum tracking state at the high density recording and realizes correct tracking. CONSTITUTION:Two or more recording heads of different azimuth angles are provided on a rotary drum. Tracking signals are recorded only to continuous two tracks among four tracks periodically. Two recording heads are adapted to be of the same track width during recording. During reproduction of signals, meanwhile, two reproducing heads carry out reproduction while being shifted from the center of the corresponding to-be-reproduced tracks, thus taking out tracking signals of the adjacent tracks at one side. The signals from the two reproducing heads are synthesized to accomplish tracking. In this case, even if one reproducing head is moved to be unable to reproduce signals due to an offtrack problem, the other head can reproduce signals, and therefore a good image can be obtained with the utilization of shifting of digital signals.
