Title: Fixing device for image forming device
Inventor: SUGIHARA KAZUYUKI
IPC: G03G21/00
Filed: 1991-10-18
Abstract: PURPOSE:To prevent the pollution of working environment and to prevent ozone from being discharged to the outside of the device at a high concn. by incorporating a perfume or ozone decomposing component into oil. CONSTITUTION:The perfume is incorporated into the fixing oil to be applied on a fixing roller by a coating felt 4. The fixing oil is applied on the fixing roller 1 of 175 deg.C surface temp. and the perfume component in the oil evaporates to release the perfume into the air in the device. This perfume is discharged to the outside of the device by an exhaust fan 11, etc., and is dispersed into a room, by which an aroma is eventually diffused in the room. The perfume- contg. oil applied on the fixing roller 1 sticks to transfer paper 10 and is discharged to the outside of the device when the transfer paper passes the nip part of both rollers 1, 3. The ozone-decomposing component in the oil evaporates and decomposes the ozone in the device by mixing therewith when the fixing oil incorporated therein with the ozone-decomposing component is used. The ozone-contg. air lowered in the concn. is discharged through an ozone filter by the exhaust fan 11.

Title: Apparatus,method and system for digital image processing
Inventor: BUHABAN AARU GANDOHI
IPC: H03M7/36
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To prevent a decrease in the compressibility of an image and an increase in the noise of a restored image by providing a means which generates a difference pixel value and a means which encodes the difference pixel value, and encoding a digital image having luminance. SOLUTION: Respective restored pixel values are multiplexed with a specific value by multiplexers 66, 68, and 70 according to flag values for reactuation and resynchronization. A subtracter 74 subtracts the value obtained by the multiplexer 66 from the value obtained by the multiplexer 70 and an absolute value calculator 76 calculates the difference value given by the subtracter 74 to generate a 1st local gradient signal Δ1 . Similarly, a subtracter 78 subtracts the value given from the multiplexer 68 from the value given from the multiplexer 70 to generate a 2nd local gradient Δ2 . Here, successive quantities found form the ratio of a local gradient function are used as weighted values of the pixel values Δ1 and Δ2 to predict pixel values. The encoding of the pixel values Δ1 and Δ2 is effective in digital image signal processing.

Title: Damper pulley
Inventor: MIZUNO NAOHIKO
IPC: F16F15/12
Filed: 1990-10-11
Abstract: PURPOSE:To increase the viscous damping force by forming a screw shaped projecting stripe on one of an outer peripheral surface of a pulley hub and an inner peripheral surface of a damper mass, forming, a screw shaped groove on the other, sealing the gap between both with the viscous fluid, and installing a rubber member for sealing the viscous fluid, permitting relative revolution at both the edge parts in the axial direction. CONSTITUTION:A damper pulley is connected, for example, to an edge part of an engine crankshaft, and a damper mass 20 constitutes an inertia mass system, and a rubber member 36 constitutes a spring, and a viscous fluid 40 constitutes a viscous damping spring-mass system. When a crankshaft revolves, and a torsional vibration is applied to the damper pulley, the damper mass 20 relatively shifts in the circumferential direction relative to a pulley hub 10. Since, at this time, a screw shaped projecting strip 12 and a screw shaped groove 22 are aslant for the circumferential direction, the interval between the side surface of the projection strip 12 and the side surface of the groove 22 becomes narrow, and the viscous damping force increases. This increase is automatically obtained, and the viscosity of the viscous fluid is increased, and the need of improving the manufacturing precision for reducing the inital interval is obviated, and the damping characteristic can be varied arbitrarily by varying the depth of the screw, number of spirals, etc.
