Title: Simple type vibrationproof supporting device
Inventor: NAGAIKE MASARU
IPC: F16F15/02
Filed: 1988-09-02
Abstract: PURPOSE:To efficiently attenuate the residual vibration and suppress the max. shift in the application of an impact to the min. by adjusting the rigtity in the horizontal direction of a vibrantionproof supporting device with high rigidity. CONSTITUTION:The regidity in the horizontal direction is adjusted by turning only the first shaft 11 and adjusting the length of the exposed part of the second shaft 12. If each of the external thread part 13 and the internal thread part 14 of the shaft 11 has an equal pitch, the level of a machine body 15 does not vary even if the shaft 11 is revolved. In the installation of the machine body 15, the distance from the bottom surface 15' of the body 15 to a floor surface, i.e., to the bottom surface 20' of a shell body 20 is not necessarily constant according to the conditions such as floor surface. Even in this case, in this vibrantionproof supporting device, the length of the exposed part of a shaft 17 can be kept constant. In other words, the value of the rigidity w in the horizontal direction (characteristic frequency of a model having a degree of freedom of -) T (time width in the action of impact force)/pi of the supporting device can be kept at a constant value in even number, and the residual vibration can be suppressed.

IPC: H04N1/40
Filed: 1991-08-30
Abstract: PURPOSE:To discriminate exactly a character and a dot picture by grouping plural data in response to information of a magnification, detecting a period change of grouped data and identifying the picture based on the period change. CONSTITUTION:A group data generating circuit 1 references magnification data at magnification to vary a read order of a memory thereby changing combinations of the grouping. The data are fed to a photograph area discrimination circuit 19, in which a character area or a photograph area is discriminated. Furthermore, the output of the circuit 1 is fed to a mean value calculation circuit 2, which calculates a mean value (density information) of densities of m-sets of grouped data. The density information is fed to a delay section 3, from which plural sets of information having delay times delayed by one dot each are generated. A density difference calculation circuit obtains a maximum value and a minimum value of the density information and compares them with a reference value latched in a reference value latch means 15. In the case of (maximum value-minimum value) < reference value, the area is discriminated to be the character area. The dot is exactly discriminated by detecting a density periodic change.

Title: Ventilating fan
Inventor: GOTO TAKASHI
IPC: F04D29/52
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To prevent the clogging and improve the maintenance property by providing a fan chamber for covering the circumference of a rotating shaft on a mounting frame for supporting an electric motor, providing a ventilating blade having a number of radial fine paths formed thereon within the fan chamber, and a taking means for taking out oil and water separated in the fan chamber. SOLUTION: When an electric motor 12 is started to rotate a ventilating blade 14 housed in a fan chamber 22 at high speed, the air present in a number of radial fine paths 35 formed on the ventilating blade 14 is run out radially by the centrifugal force, while air is sucked through an inlet port 18 and run into the fine paths 35 from the inside. The air flow sent from the ventilating blade 14 is turned to the rear, carried to a rear casing 13 through vent holes 19 formed on a bulkhead 16, and discharged to the atmosphere through a rear exhaust port 17. At this time, the oil drop or water drop accompanying the air flow is radially shaken off and adhered to the inner wall of the fan chamber 22 since its specific gravity is different from that of the air flow, whereby the oil drop or water drop is separated from the air, run down and accumulated.

Title: Method for measuring deviation in circumferential direction of dropping speed of material loaded into shaft furnace
Inventor: MATSUMOTO TOSHIYUKI
IPC: G01J5/00
Filed: 1983-11-25
Abstract: PURPOSE:To detect easily and surely the ununiform state in the circumferential direction of the dropping speed of a material loaded to the lower part of a furnace, by measuring the temperature of the front of tuyere. CONSTITUTION:A contactless thermometer 11 which can measure the temperature of the front of plural tuyeres attached in the circumferential direction of a funace body is provided in a viewing window 12 of a bend part of a blast branch pipe 9. Thermometers 11 are provided for all tuyeres or plural tuyeres at intervals of a certain length in the circumferential direction. The temperature of the front of tuyeres measured by these thermometers indicates a value corresponding to the heat incoming and outgoing state of a combustion zone in the front of tuyeres. Though this heat incoming and outgoing state is varied by various factors, it is determined by a ratio O/C of ore raw materials to fuel in the top of the furnace if the other conditions are fixed. Then, the ratio O/C of the material loaded to the shaft furnace is changed by >=10% of normal operation, and dropping of this changed loaded material to the front of tuyeres is detected as a variance of temperature by thermometers for measuring the temperature of the front of tuyeres. The differences between the time of the change of the ratio O/C and the time of the detection of the temperature change in individual tuyeres are compared with one another, and this time difference is obtained as deviation of the dropping speed of the loaded material in the circumferential direction.

Abstract: PURPOSE:To easily produce composite metallic powder in which dispersion particles are uniformly distributed by charging the granular or short fiber-like dispersion particles having the m.p. higher than the m.p. of a molten metal to the molten metal and splitting and spraying the melt mixture composed thereof to liquid drops by centrifugal force. CONSTITUTION:A rotary electrode 3 made of an Ni alloy, etc., is erected on an electrode mounting base 8 which is horizontally rotated by a high-speed revolving motor 4 to constitute a centrifugal sprayer consisting of a rotary electrode device. Said electrode is rotated at a speed of about 16,000 revolutions/ min and an arc 1 is irradiated from above the rotary electrode 3 to form a molten metal pool 2 at the top end thereof. The dispersion particles 6 in the granular or short fiber-like state having the high m.p. are thrown to the molten metal just prior to splitting to the liquid drops in the molten metal pool 2 from a nozzle 5 disposed in the upper diagonal position. Such melt mixture is split by the centrifugal force. The composite metallic powder in which the above- mentioned dispersion particles are uniformly distributed is thus easily and quickly formed at a low cost.

Filed: 1989-08-30
Abstract: PURPOSE: To obtain carbon black particles having surface activity and uniform quality by gradually increasing the diameter of an outlet chamber, equalizing the residence time of a thermal decomposition reaction product and preventing excess thermal decomposition.  
     CONSTITUTION: By gradually increasing the diameter of an outlet chamber toward an outlet opening part, a reaction equipment produces high temperature gas flow, and the high temperature gas flow is directed in the axial direction within the reaction equipment. By introducing feedstock hydrocarbon into the high temperature gas flow in the axial direction, the flow of thermal decomposition reaction product in the axial direction is formed. By gradually increasing the diameter of the outlet chamber, the plug flow of the thermal decomposition reaction product passing through the outlet chamber and an outlet chamber having small volume than the suddenly widened outlet chamber, having the same length are formed, and the residence time of the thermal decomposition reaction product is equalized. As a result, the reaction product is uniformly thermal-decomposed, and activity on the surface of carbon black particles is kept.

Title: Spindle motor
Inventor: BABA TERUO
IPC: G11B19/20
Filed: 1988-09-05
Abstract: PURPOSE:To obtain an inexpensive motor whose built-in accuracy of parts in an axial direction is high and which can be easily assembled by using only a metal bearing as a bearing and receiving a load in the axial direction by receiving one end of the anti-output shaft side of a motor main shaft by a motor frame through an abrasion-resistant material. CONSTITUTION:A motor main shaft 21 receives the load in the radial direction by an oiled metal bearing 22 and receives the load in the axial direction by a motor frame 26 through a polyslider 31, etc., with good abrasion resistance. By the distance from the contact face of the polyslider 31 to the center of rotation being short and lubricating with metal oil, a frictional load becomes small, by making the clearance of the bearing small, shaft looseness at the tip 21a of the motor main shaft can be made sufficiently small and the dispersion of height becomes small. Thus, it becomes unncessary to adjust the height of a hub 25 and the inexpensive spindle motor which can be easily assembled can be obtained.

Title: Image forming device
Inventor: HANDA OSAMU
IPC: G03G15/16
Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To almost eliminate the bad effect of the dispersion in resistance distribution or resistance change in environmental change of parts such as an intermediate transfer belt and a backup roll or secondary transfer roll on transfer performance by constituting the intermediate transfer belt by use of an ion conductive semiconductive material and the backup roll or secondary transfer roll by use of an electron conductive roll. SOLUTION: An intermediate transfer belt B is formed of an ion conductive type semiconductive material or molecule dispersion type semiconductive material with dispersed conductive particles, whereby the transfer unevenness resulted from the resistance unevenness of the intermediate transfer belt B can be suppressed. The resistance of the ion conductive type intermediate transfer belt B has environmental dependency, and it is particularly low under high temperature and high humidity. Therefore, at least, one of the semiconductive surface layer of a backup roll T2a or the semiconductive layer of a secondary transfer roll T2b is formed of an electron conductive type semiconductive material with little environmental fluctuation of resistance.  Accordingly, even if the resistance of the intermediate transfer belt B is reduced under high-temperature and high-humidity environment, heavy current can be prevented from being carried.
