Title: Development device
Inventor: OKA SEIJI
IPC: G03G15/08
Filed: 1990-10-15
Abstract: PURPOSE:To prevent toner scattering and void by forming a magnet roller which constitutes a developing roller integrally with a roller shaft and providing plural developing rollers. CONSTITUTION:A 1st developing roller 12 and a 2nd developing roller 13 are provided in a casing 15. The 1st developing roller 12 and 2nd developing roller 13 has the same structure, and the roller shaft 36 which extends in a thrust direction is fixed to both end parts of the magnet roller 35, which is formed integrally with the roller shaft 36. Therefore, toner can be supplied plural times to an electrostatic latent image on a photosensitive body and thus a sufficient amount of toner can be supplied to the electrostatic latent image without increasing the linear speed of a developing sleeve 37. Consequently, trouble such as toner scattering and void is not caused and the small-sized development device which copes with a fast copying speed is obtained.

Abstract: PURPOSE:To simplify application to a small-quantity multiproduct production, and achieve a mass production with reduced labor by moving first holders and second holders linearly back and forth, and regulating a distance between a peeling blade and a cutting blade of each holder. CONSTITUTION:When a slide body 5 slides along a guide rail 3 by an eccentric roller 26 of a gear interlocked and engaged with a crank mechanism, first holders 8a, 8b and second holders 16a, 16b slide inward along slide beams 11, 17. Cutting blades 4a, 4b then cut a wire W. Simultaneously, peeling blades 7a, 7b, 15a, 15b make a cut in the wire W. Feed action of the roller 25 is then inverted for pulling it back, so a strip is formed at one end part of the wire W.

Title: Developing device
Inventor: TACHIKAWA MASAICHIRO
IPC: G03G15/08
Filed: 1986-11-19
Abstract: PURPOSE:To supply the same amount of toner as consumed toner in a developer to a containing part from a hopper and to keep the toner concentration in the developer almost constant by providing a partition means with plural opening holes and an agitating means agitating a developer in a developer containing part. CONSTITUTION:The toner in the developer 14 is used by a developing action to develop a gap equivalent to the volume of the consumed toner in the containing part 16, and a fresh toner goes into the containing part 16 through the opening holes of the partition 24 from the hopper. When the volume of the developer 14 in the containing part 16 increases to its initial level, an agitating action inhibits an excessive toner from entering, whereby the developer 14 maintains almost the same toner concentration as in an initial state. By amplifying the agitating action in the developer containing part 16, an agitating vane 26 agitates and mixes the toner supplied from the hopper with the developer in the developer containing part 16 to speed up the electrostatic charge of the toner, and functions so that the toner can have an electrostatic charge amount enough to develop satisfactorily. Simultaneously the vane 26 homogenizes the developer and minimizes the unevenness of the toner concentration.

Title: Device and method for detecting home position
Inventor: AKI SHIYOUYOU
IPC: G01D5/12
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To shorten a home position detecting time and to reduce noise or consumption power at a time of the movement of a carriage for detecting a home position. SOLUTION: A home position is detected by two sensing pieces 18a, 18b provided at a predetermined interval along the moving direction of a carriage 12 along a shaft 14 and the home sensor 20 such as a photosensor arranged at the predetermined position in the moving process of the sensing pieces 18a, 18b. The carriage 12 is additionally moved so that the sensing piece 18b set to a standard comes to the sensing position of the home sensor 20 after the carriage 12 is moved from a stop position so that either one of the sensing pieces 18a, 18b is sensed by the home sensor 20 to detect a home position.  The home position is detected heretofore by always moving the carriage at a low speed regardless of the carriage position at the start time of positional detection but, since low speed control can be performed only in a short section by the combination of high speed movement and low speed movement corresponding to the carriage position at the start time of positional detection, a home position detecting time is shortened.

Title: Plasminogen activator producing cell
Inventor: SHIYAMU WAI CHIYAN
IPC: C12N9/72
Filed: 1990-10-17
Abstract: PURPOSE: To obtain biologically pure cell culture that produces plasminogen activator in an increased yield and is obtained from a plasminogen activation factor-producing cell line and deposited as PC-3f (ATCC No. CRL-8539).  
     CONSTITUTION: In order to increase the yield of plasminogen activator(PA) obtained from the cell line that produces plasminongen activation factor, the PA-producing cells are proliferated in a suitable growth culture containing fetal calf serum (or bovine serum). Then, the PA-producing cells are subinoculated in one series of the above-stated cell growth culture medium in which the amount of fetal calf serum is decreased in order thereby allowing the PAproducing cells to adapt to the culture medium substantially containing no fetal calf serum. When the cell line is adapted, a biologically pure tissue culture ATCC CRC-1622 and ATCC CRC-1579 is obtained that can produce a relatively large amount of PA.

Abstract: PURPOSE:To simplify the input work of a mesh division value by introducing the concept of parametric design to mesh division design. CONSTITUTION:A two-dimensional CAD data processing part 120 has a function resembling the function of a normal two-dimensional CAD device and stores position information and dimensions of graphic elements inputted from an input part 110 in a prescribed form and stores a division value for mesh division in the form of a parameter and its value while interlocking with the corresponding graphic elements. Since two dimensional-three directional transformation part 130 converts the data from the two-dimensional CAD data processing part 120 into the data for the preparation of a three-dimensional graphic form, the three-dimensional graphic form prepared based on converted data by a three-dimensional data processing part 140 is sent to an analysis model forming part 150. A load condition, a restrictive condition, and physical property values are sent to the analysis model forming part 150 from the input part 110, and an analysis model subjected to mesh division is prepared based on these data.
