IPC: B01D53/34
Filed: 1992-04-17
Abstract: PURPOSE:To specially reduce the noise of a ventilation fan, to prolong the life of an ozone filter and to prevent the abnormal temperature of a device from rising as for an image forming device such as a copying machine or an electrophotographic printer having the generating source of ozone on the inside of the machine. CONSTITUTION:By incorporating an EEPROM 10 in the ozone filter 8 which can be exchanged in the image forming device 1 and incorporating a timer in a one-chip CPU 11, the using time of the device after the filter 8 is exchanged is counted by the timer and the fan control data of the ventilation fan 9 corresponding to the using time is calculated. Then, data corresponding to the calculated result is read out from the EEPROM 10. Based on the data, the rotation of the fan 9 is controlled. By executing the control in such a way, the rotation of the fan 9 can be controlled according to the using time of the filter 8 and fixed ventilation ability can be held regardless of the clogging state of the filter 8 or the like.

Title: Magnetic polishing method
Inventor: HATANO SHIGETO
IPC: B24B31/112
Filed: 1985-05-10
Abstract: PURPOSE:To polish the entire face of short and complex part uniformly with high accuracy by facing the pole faces of a pair of magnetic poles through uniform gap against the coarse machining face of work and arranging a pair of magnetic poles while shifting in longitudinal direction of the drum face of work or in lateral direction of the upper face. CONSTITUTION:A pair of magnetic poles 3, 7 (or 10, 11) are faced through uniform gaps 4, 5 (or 12, 13) against the machining face of work 1. The magnetic poles 3, 7 are arranged while shifting in longitudinal direction of the drum face of work 1 (or in lateral direction of the upper face of work 1, in case of the magnetic poles 10, 11). Consequently, the drum face or the upper and lower faces of work 1 are covered entirely by magnetic abrasive grains to prevent dispersion of the magnetic abrasive grains thrown into the gaps 4, 5 (or 12, 13) upon rotation of work 1. While since the magnetic abrasive grains will adhere and move against the surface of work repeatedly to provide a new edge, the entire face can be polished uniformly with high accuracy.

Abstract: PURPOSE: To improve durability of an antivibration device without deteriorating durability of a diaphragm by pressing a projection formed on a diaphragm projected toward an outer cylinder side, moving the diaphragm inward, and thereby regulating deformation of the diaphragm. CONSTITUTION: A diaphragm 26 which composes a part of a partition wall of a sub-liquid chamber 38 integrated with an elastic body 16 has a stopper projection 40 projected toward an outer cylindrical fitting 18. In assembling an antivibration device, the stopper projection 40 is in contact with the outer cylindrical fitting 18 and thereby pressed to the side of an inner cylindrical fitting 14. The diaphragm 26 is moved to the side of the inner cylindrical fitting 14. Since the diaphragm 26 is integrated with an elastic body 16, a manufacturing cost of the antivibration device 10 is reduced. Deformation of the diaphragm 26 is regulated in a vertical, that is, extension/contraction direction of the diaphragm 26 by the stopper projection 40 and the inner cylindrical fitting 14.

Filed: 1993-04-01
Abstract: PURPOSE:To produce the subject agent which forms a flame-retardant inorg.-org. composite having a high foaming ratio and excellent durability and solidification strength by combining an aq. sodium silicate soln. contg. a polyol with a liq. org. polyisocyanate compd. CONSTITUTION:This agent is of a two-component type, comprising component A consisting mainly of an aq. sodium silicate soln. contg. a low-mol.-wt. polyol having a hydroxyl value of 750-1,900 and component B consisting mainly of an org. polyisocyanate compd. Since the agent has a low viscosity, is excellent in penetrating properties, and can have a high foaming ratio, it well penetrates into gaps whereinto a conventional agent hardly penetrates, thus enabling the solidification of ground, etc. High compatibility of the polyol with water glass enables the formation of a homogeneous solidified zone. The agent is economical since a sufficient solidification strength is obtd. even when the foaming ratio is high, and the agent IS excellent in flame retardancy since it forms an inorg.-org. composite.

Abstract: PROBLEM TO BE SOLVED: To reduce the possibility of careless disturbance to feeding of a recording sheet to attain proper printing in an electronic camera having a printer section. SOLUTION: The electronic camera has an LCD 26 fitted to an enclosure of the camera to reproduce and display image data as a video image and a printer 7 to print out an object image onto a photographic recording sheet.

Title: Microcomputer system
Inventor: SATO OSAMU
IPC: G06F1/24
Filed: 1986-04-28
Abstract: PURPOSE:To avoid the malfunction of a CPU by inhibiting the release of a reset state of the CPU when a clock circuit has abnormal vibrations. CONSTITUTION:The reset time of a reset circuit 3 is usually is much longer than the time during which the output of a clock circuit 2 reaches the sufficient amplitude. Thus, the output of a shift register 5 has the logic of the reset state of a CPU 1 because the clear input is cleared when the clock signal is applied last to the register 5. Under such conditions, the reset time passes and the output of the circuit 3 is changed to the logic of the reset release. Then the register 5 starts its working. When the circuit 2 is set under high-degree oscillation state of a three-fold wave in an application mode of a power supply, the clock signal is supplied to the CPU 1. However the clock signal is not applied to the clock input CLK of the register 5 since this signal is prevented by a BPF 4. As a result, the output of the register 5 has no change although the output of the circuit 3 has the reset release logic. Thus the CPU 1 is not actuated.

Title: Method and device for generating character and pattern
Inventor: SUZUKI TSUGI
IPC: G09G5/20
Filed: 1989-04-19
Abstract: PURPOSE:To efficiently generate a character and a pattern faithful to the original one as much as possible by extracting a maximum and a minimum points from the point string of a contour point, and executing the integerizing processing of coordinate after correcting the coordinate value of each contour point on the basis of the coordinate values of these maximum and minimum points. CONSTITUTION:A CPU 101 at first reads out successively the point numbers of the maximum and the minimum points stored in a maximum and minimum point storage part 103, and after reading out the coordinate data of the contour point corresponding to that point number from a coordinate initial value storage part 102, it integerizes this coordinate value, and stores this result in a coordinate integer value storage part 104. Then, after integerizing the coordinate values of all the contour points, it sends the integerized coordinate data to a contour line generating part 105, and generates a contour line, and further, by painting all over the inside, the character and the pattern of necessary size are generated. Thus, the jump-out or the drop-out of a dot accompanied with the integerizing processing of the coordinate can be avoided, and the coordinate of the contour point of the character and the pattern of the optional magnifying factor can be generated more faithfully to the design of the original character.
