Title: Fluid pressure cylinder
Inventor: KUNIMOTO ETSUO
IPC: F15B21/04
Filed: 1993-04-27
Abstract: PURPOSE:To discharge a fluid that has deteriorated due to temperature rise and wear powder or the like in pressure chambers and piping, by providing a passage to connect the two pressure chambers to each other. CONSTITUTION:A passage 20 to connect a pressure chamber 3 and a pressure chamber 4 to each other is provided, and both ends of the passage 20 are on the outsides of wear rings 12 and are opened to the outer periphery surface of a piston 2. A throttle 21 is interveniently furnished to the passage 20. At the time of cylinder 1 operation, when, for example, pressure oil is introduced into the pressure chamber 3, part of the pressure oil enters into the pressure chamber 4 through the passage 20 and the throttle 21, and joins with the oil in the pressure chamber 4 and is discharged little by little. Conversely, when pressure oil is introduced into the pressure chamber 4, part of the pressure oil enters into the pressure chamber 3 through the passage 20 and the throttle 21 and is, together with the oil in the pressure chamber 3, discharged into a tank 10. Thereupon, during the operation of the cylinder 1, the oils in the chambers 3 and 4 change places with each other gradually, so there is no chance of deteriorated oil staying in the chambers 3 and 4. Also, a foreign matter smaller than an opening between the piston 2 and the cylinder 1 can be deterred from entering into the passage 20, so the clogging of the throttle 21 can be prevented.

Inventor: ISOKAMI HISASHI
IPC: B03C1/025
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To improve the treatment efficiency of a magnetic separator. SOLUTION: A passage is formed so that a fluid to be treated, which flows in from an inlet 10, is discharged from an outlet 33 to the outside after the fluid passes through a bore part 3 of a magnetic field generation means 1 and magnetic matter is attracted and separated by a magnetic filter 4 which receives the magnetic field generated by the magnetic field generation means while the fluid to be treated is flowing downward in the passage. An expansion part (filter frame 12) is installed in the passage to expand a cross sectional area of the passage while changing the flow direction of the fluid to be treated, which has flowed in from the inlet, to the direction perpendicular to the flow-in direction, and the magnetic matter in the fluid to be treated is attracted and separated after passing through the expansion part.  As a result, the magnetic matter in the fluid to be treated can be precipitated and separated in the expansion part before being attracted and separated by the magnetic filter, thereby reducing the load of the magnetic filter and improving the treatment efficiency of the magnetic separator.

Filed: 1980-09-05
Abstract: PURPOSE: To prevent the generation of a difference between surface properties of front and underside of a rolled strip, by offsetting the horizontal positions of upper and lower work rolls, when a strip is rolled by upper and lower work rolls rotated at different circumferential roll speeds.  
     CONSTITUTION: An upper work roll 12 and a lower work roll 14 are respectively rotated at different circumferential speeds v 1 , v 2 , for rolling a strip 10; hereupon, the center of the lower work roll 14 is offsetted by a distance δ toward the strip's feed-in side. Or otherwise, on the contrary to that, the lower work roll 14 is similary offset to the strip's run-out side, and the rolling work is practiced under this condition. In general, at a rolling method with different circumferential roll speeds, if v 1 >v 2 , the friction factors μ 1 , μ 2  between the strip 10 and the upper and lower work rolls 12, 14 are in a relation μ 1 <μ 2 ; as an effect of these different friction factors, the luster, roughness, etc., of a strip 10 differ between the front and underside so that its surface property becomes declined; however, by offsetting the positions of work rolls 12, 14, the friction factors μ 1  and μ 2  become almost equal, so that the difference between the surface properties of the strip's front and underside is eliminated.

Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To expand the service area to a wide area corresponding to a wide area DGPS(differential global positioning system) in spite of a system scale of a local area DGPS, to provide very high reliability for an integrity determining function. SOLUTION: Observed data of DGPS reference stations A-E are transmitted to a central control station CTR to calculate a time error between the adjacent reference stations by a computor system. A service area-overlapped area is basically used for a common view of the adjacent fellow DGPS reference stations, and finally chained time synchrinization is conducted over the whole reference stations A to E. The time synchronization between the reference stations, observation of an ionospheric layer lag and calculation of a tropospheric lag are carried out in correction information generation of a local area DGPS to broadcast a pseudo-distance component of a satellite orbit error in addition to ordinary DGPS correction information. Local area DGPS positioning on the user side is smoothened thereby to realize a wide area service.
