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.

摘要： PURPOSE:To achieve a higher processing capacity and a lower production cost, by carrying out the work of changing discs for other spindles while one spindle undergoes an error test to lower the performance of a tester. CONSTITUTION:A tester is made up of a single plate disc driving section in which a plurality of rotary spindles 3 are set with several single discs piled radially and four error testing circuits 10. Then, a test head changing circuit 8 is provided to change over the circuit 10 per spindle and while one spindle 3 undergoes an error test, the work of changing discs is done for other spindles 3. Thus, when a spindle is connected to the circuit 10 by switching, the error processing can be started immediately.

摘要： PURPOSE: To permit energy economization by installing a reaction plate onto each flat car in a flat-car train and installing a linear motor coil for generating the force for driving, brake application, and positioning through the reaction plate.
CONSTITUTION: A linear motor LIM1 and the reaction plate RP1 of a flat car C1 are positioned at the corresponding positions, and the flat cars C1WC5 are shifted rightward by the excitation of the coil of the motor LIM1 and the application of a force onto the plate RP1. When the flat car reaches a certain position, the excitation of the coil of the motor LIM1 is suspended, and the coil of a motor LIM4 is excited to generate a brake power between the plate RP5 of the flat car C5 and the motor LIM4, and the flat car group C1WC5 are electrically stopped. The position control for the flat cars C1WC5 is performed by the operation force between the motor LIM2 and the plate RP1 and the operatio force between the motor LIM3 and the plate RP4. Since the driving, brake application, and positioning can be electrically carried-out, the weight of the flat car can be reduced.
