Abstract: PROBLEM TO BE SOLVED: To prevent generation of frictional powder generated by being brought into contact a ball and a shaft with each other, and ensure smooth performance by arranging a plurality of balls between a locus groove arranged on a thrust receiving surface and a locus arranged on a thrust bearing surface. SOLUTION: In a bearing device, a locus groove 2a which is concentrically with an outer diameter surface of a shaft is arranged on a thrust receiving surface 2b as an end surface of a shaft 2, radial bearing surfaces 5b are arranged on an inner diameter surface of a sleeve 5 and on two positions separated in an axial direction, and a radial receiving surface 2c provided with a groove for generating dynamic pressure is formed on the shaft 2. When current- carrying is carried out to a motor, a rotary magnetic field is generated, a rotor is rotated, and a rotary member provided with a housing 3 is driven, a plurality of balls arranged between the thrust receiving member 4 and the shaft 2 are rotated while being brought into rolling-contact. The clearance between three or more balls 1 is held to a constant level, and the rotation of the thrust receiving member 4 is smoothly carried out.  It is thus possible to reduce a torque, and it is also possible to prevent generation of frictional powder.

IPC: G01F1/32
Filed: 1994-04-21
Abstract: PURPOSE:To realize a high sensitivity detection by detecting a vortex frequency from an envelope of amplitude modulation signals being sampled thereby eliminating the influence of noise effectively.

Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To obtain a propylene homopolymer which has a tackiness point shorter than 30cm during melt spinning, has an oligomer content lower than 1,500ppm without undergoing postpolymerization for oligomer removal, and has a melt flow rate higher than 300dg/min. SOLUTION: A propylene homopolymer which has a tackiness point shorter than 30cm during melt spinning, has an oligomer content lower than 1,500ppm without undergoing post-polymerization for oligomer removal, and has a melt flow rate higher than 300dg/min is produced with a multistage fluidized bed reactor through radiation visbreaking. The homopolymer is irradiated in a substantially oxygen-free state and then subjected to a multistage treatment in the presence of a regulated amount of oxygen. This radiation visbreaking method is applicable to other propylene polymers. Propylene polymer materials produced by this method are usable, e.g., n extrusion coating, film production, and injection molding.

Title: Variable speed device of auxiliary machine and detection method of belt-slip
Inventor: AIBA SATOSHI
IPC: F16H59/42
Filed: 1992-04-06
Abstract: PURPOSE:To prevent a slip of a belt without lowering speed changing efficiency by providing a pulley revolving speed detecting means, a pulley groove width detecting means, and a groove width controlling (increasing/decreasing) means and exercising such control as to decrease the groove width as soon as the belt-slip is detected by any one of the above detecting means. CONSTITUTION:Revolving speeds NR, NN of a driving side pulley 6 and a of a driven side pulley 9 are detected by revolution sensors 53, 79, while gaps between reference planes 63, 89 of the pulleys 5, 9 and gap sensors 65, 91 are detected by the gap sensors 65, 91. From these detected values, an ideal revolving speed NNi of the pulley 9 is calculated, and, if a difference DELTAN between this calculated value and the revolving speed NN of the pulley 9 is either non- zero or greater than a preset value, it is judged that a metallic belt 11 is slipping. To cope with this, it is necessary to increase the thrust of the pulleys 5, 9. However, since a speed change ratio should not be changed, the working oil pressure in both driving side working chamber 61 and driven side working chamber 87 of the pulleys 5, 9 is raised until the slip is stopped. With this contrivance, the slip of a belt can be prevented.

The waste water is once stored in a tank 4, and fine particle metallic powder of about ≥20μ, carbonized materials and other insoluble contents are eliminated from the waste water through a filter device manufacted with resin 5. The filtered water is once stored in a tank 6 then sent to a blender 7 to be blended with heavy oil supplied from a heavy oil tank 8. Thus an emulsion fuel is obtained. It is preferable to set the blending ratio at about 20W25:80W75 (volume ratio) between the waste water and the heavy oil.

Filed: 1989-04-04
Abstract: PURPOSE:To reduce the gain adjustment time by setting the gain to the final gain in the three-stage check operation when an analog value is converted in to an object value via a programmable amplifier whose gain is set with a digital value. CONSTITUTION:A detection signal input 6 being an analog voltage is inputted to an input terminal IN of a programmable amplifier 2. A gain of the amplifier 2 is set to be 1/2 in the gain setting range and a half of the setting value is stored as a difference. Moreover, the gain setting value is given to the amplifier 2, its output is sampled, and in the case of output value > object value, a value of gain-difference is used as a new gain setting value. Furthermore, in the case of output value < object value, a gain setting value + differential value is used as a new gain setting value and a half the differential value is stored as a new differential value. Moreover, in the case of output value = object value, the gain setting value at that time is used as the final gain value.
