摘要： PURPOSE:To use natural water flow effectively and surely retain constant power without running cost by using a water wheel as a source for aeration work, etc., in a lake and marsh cleaning apparatus to clean water in lakes and marshes by aeration, etc. CONSTITUTION:In the case that aeration, etc., of water in a storage pond is carried out to improve the quality of water in lakes and marshes, a water wheel is used as a power source for the aeration work, etc. In other words, the natural water flow is used to provide rotary force to the water wheel 1. The rotary force of the water wheel 1 is transmitted to propellers 4 for stirring installed in the surfacial water layer under water through the combinations of a plurality of shafts 2 (a-c) and gears 3 (a-e). Consequently, the propellers 4 for stirring are rotated and water in the deep water layer is pumped and circulated to the surfacial water layer and thus water is cleaned. As a result, the contained in energy the natural water flow is used effectively.

摘要： PURPOSE:To increase the removal amount of nitrogen and phosphorus at about two times in comparison with a removing method based on a conventional aquatic plant and to efficiently recover water-bloom by making absorbed and immobilizing nitrogen and phosphorus in water on waterbloom and separating water-bloom from water with a precoat filter. CONSTITUTION:Water-bloom described below is positively propagated in a raw water tank 1 and nitrogen and phosphorus in water are absorbed immobilized. This water-bloom is speedy in propagation velocity and high in absorption and immobilization capacity of nitrogen and phosphorus per unit dry weight. Water-bloom is sucked with a feed pump 5, separated by a precoat filter and dehydrated. By this removing method effect of about two times is obtained in comparison with a removing method based on a conventional aquatic plant and treatment of water bloom is made easy.

摘要： PROBLEM TO BE SOLVED: To faithfully simulate and load an actual dynamic load and an actual static load by controlling a shaker in such a way that the measured value of a shaft-part actual model which models a bearing, to be tested, and a shaft part facing the bearing to be tested agrees with the calculated result of a shaft- part numerical model which is numerically modeled in a computer. SOLUTION: A shaft 5 which is supported by a bearing 3 and a bearing 3 is turned and driven by a driving source. The shaft part of a rotating machine system is simulated via a housing 4 and a housing 4 by a shaker 6 and an exciter 6 which are fixed to a rigid wall 12. A bearing 1, to be tested, which is inserted and mounted near the center of the shaft 5 is housed in a housing 2, and the measured value of a reaction force which is measured by a measuring device 7 is input to a computer 11. Then, the computer 11 inputs a shaking signal to a control device 8 for the shakers 6 via a signal transmission means 17 in such a way that the measured value of a shaft-part actual model which models the bearing to be tested and a shaft part facing the bearing to be tested agrees with the calculated result of a shaft-part numerical model which is numerically modeled in the computer 11, and the shakers 6 are controlled.

摘要： PURPOSE:To aim at shortening of the track time of picking work by comparing natural frequency of a manipulator driven mechanism system in each axial direction and stopping the shaft of lower natural frequency first. CONSTITUTION:Regarding a picking device which takes out the desirable article from an out-going rack by an orthogonal three axle manipulator, as a driving method of simultaneously driving two axles or a plurality of axles among the manipulator driven axles, for example, in case of simultaneously driving two axles, a shaft of lower natural frequency is stopped first. Thus amplitude of the residual frequency in the direction of the shaft of lower natural frequency starts damping earlier than the shaft of high natural frequency. When the shaft of high natural frequency stops, the amplitide of the residual frequency of the shaft which stopped eariler has become sufficiently small. The time required for damping of the residual frequency is short if the natural frequency is high. Therefore frequency settling time after stopping can be set short and the tact time of the picking work can be shortened.

摘要： PURPOSE:To secure operation necessary for respective operations, and increase cycle time by carrying out stopping position control on respective shafts with every continuous operation according to the preset content in a picking device having an orthogonal triaxial manipulator. CONSTITUTION:A picking device having an orthogonal triaxial manipulator carries an object 14 from a magazine 2 of a rack 1 by a roller conveyor 4 through a delivery bucket 3. On the other hand, a travel carriage 5 is driven through a timing belt 7 by a traveling motor 6. A raising-lowering body 9 is driven through a timing belt 11 by a raising-lowering motor 10, and a hand part 12 is installed on an arm shaft 13 capable of advancing and retreating, and the object 14 is gripped. In this case, when operation up to a delivery box from a delivery shelf is carried out continuously, a stopping positioning accuracy value is set individually in three shafts with every operation. Stopping position control on respective shafts with every operation is carried out according to the preset content.

摘要： PURPOSE:To prevent adsorption to a magnetic head by constituting a press contact part between a supporting base supporting the outer circumference and the magnetic disk by a material having oil absorbing property so as to form the lubricant coating film on the surface of the magnetic disk to be uniformly thick. CONSTITUTION:The magnetic disk 1 supported by the supporting base 4 via an oil absorbing member 8 is immerses in a lubricant tank 2 as it is and then lifted up to be subjected to lubricant film forming. Since no liquid is contained in the member 8 at the initial state before being immersed, the absorbing capability is 100%. When the disk 1 is immersed in the tank 2, the liquid is absorbed and the oil absorbing capability is 0%. When the disk 1 is lifted up slowly in the tank 2, since the liquid of the member 8 is evaporated, the oil absorbing capability of the member reaches rapidly nearly 100%. Then the pooled part to be caused absorbed and eliminated. Thus, no diffused part exists or is caused.
