Title: Magnification changing device for copying machine
Inventor: FUKUNAGA TAKAHIRO
IPC: G03G15/04
Filed: 1979-10-05
Abstract: PURPOSE:To obtain a magnification changing device that makes the angle of reflection coincide with the angle of projection when changing magnification using a simple structure by inclining the optical axis for changing magnification and, at the same time, inclining a reflection mirror according to the angle of inclination of the inclined optical axis. CONSTITUTION:When making reduced copying, a pulley 25 is rotated counterclockwise by a motor 24. Then, a support 21 is slid and a reducing lens 6-2 is positioned in the light path. Linked with said rotation, a shaft 28 is rotated and a reflection mirror 20 for reducing rises up in the light path oppositely. Here, the optical axis of the reducing lens 6-2 is inclined and the reflection mirror 20 for reducing is inclined according to the inclination of the lens 6-2. Accordingly, an optical image produced by the reducing lens 6-2 is projected on the surface of a photosensitive drum 8 through the same light path with that in case of the reflection mirror 7 for unmagnification copying by reflection of the reflection mirror 20. In this way, the angle of reflection theta1 can be made equal to the angle of projection theta2 in case of reduced copying too, and thereby an accurate reduced copy can be obtained.

IPC: G11B21/02
Filed: 1978-10-24
Abstract: PURPOSE: To prevent the abnormal rotation and racing of turntable, by giving greater gear ratio between the drive shaft of driving flywheel and turntable.  
     CONSTITUTION: When the drive idler 16 is depressed toward the arrow B and it is closely located between the drive shaft 14a and the turntable 4 for the circumference, the drive force of the drive motor 13 is delivered with greater gear ratio in the order of the pulley 13a-belt 15-flywheel 14-drive shaft 14a-idler 16-table 4 to turn the table 4 toward the arrow D. When a force causing abnormal rotation toward the arrow D during constant rotation of the table 4 is exerted, the idler 16 is moved and the abnormal rotation and racing prevention idler 17 is sticked strongly between the shaft 14a and the table 4. As a result, since the gear ratio between the flywheel 14 and the table 4 is greater, brake effect is caused to avoid the abnormal rotation of the table 4. Further, when the force toward the arrow E is exerted on the table 4, the idler 17 is moved, 16 is sticked, allowing to prevent the abnormal rotation similarly.

Title: Modification of cellulose fiber
Inventor: ISOHATA TOSHINARI
IPC: D21H11/16
Filed: 1995-05-29
Abstract: PURPOSE: To modify cellulose fibers by partially converting cellulose pulp with a specific dissolving agent into amorphous forms in a specified amorphous range degree, and further to produce a sheet having an excellent strength by a wet paper production method using the modified cellulose fibers. CONSTITUTION: A method for modifying cellulose fibers comprises immersing bleached craft pulp as cellulose fibers in a dissolving agent, charging the treated bleached craft pulp in water to stop the amorphous reaction and produce the partial amorphous regenerated pulp fibers, and subsequently washing the treated pulp. The cellulose fibers are thus modified in a cellulose fiber amorphous degree of 0.5-17%. The cellulose fiber amorphous degree is defined by an equality: the amorphous degree = 100 - (the crystallinity of the cellulose fiber sheet treated with the dissolving agent for the amorphous treatment)/(the crystallinity of the cellulose fiber sheet not subjected to the amorphous treatment) × 100}.  The dissolving agent is produced by dissolving sulfur dioxide and diethylamine in amounts of 0.4-2.0 moles and 0.4-2.0 moles, respectively, per unit of the glucose group of the cellulose in dimethylsulfoxide so as to give a molar ratio of 0.8-1.5 between the sulfur dioxide and the diethylamine, and used for converting the cellulose into the amorphous form. The obtained modified cellulose fiber pulp slurry is processed into a sheet having an excellent strength.

Title: Picture image reading method
Inventor: MORI MASANORI
IPC: G06K9/38
Filed: 1984-06-25
Abstract: PURPOSE:To always set a threshold level for optimum picture image reading by photographing previously a reference pattern of the prescribed density with which the picture image characteristics are previously known to a microfilm within a prescribed range of linear density. CONSTITUTION:A reference pattern 13 is photographed previously at a prescribed position of a microfiche film 10 for measurement of an MTF showing the performance of a lens system. In a reproduction mode the data on each linear density of the pattern 13 is stored to an MTF data memory 2 by a switch signal SW. Then a switch SW is changed toward a contact 1B to read each picture image of a frame 12 to supply them to a shift amount detecting part 3 as well as to a linear density detecting part 4. Thus the minimum value S and the linear density T are detected. The density T reads out the peak-peak value H of the corresponding linear density stored already to the memory 2 and is divided at a control part 6 to be supplied to an address circuit 5. The output of the circuit 5 is used as a threshold level F.
