Title: Torque transmission variable device
Inventor: NISHIBORI KENJI
IPC: F16D37/02
Filed: 1991-10-18
Abstract: PURPOSE:To control whether torque is transmitted or not by setting a space between a cover unit and a non-magnetic upper disk smaller than a space between the upper disk and a magnetic lower disk in a closed chamber, connecting both the spaces, and adjusting level height of magnetic fluid in the closed chamber to come into contact with or to approach a lower surface of the upper disk. CONSTITUTION:In a condition of demagnetizing an electromagnetic coil 15, since shear force of magnetic fluid 12 in a closed chamber 11 is generated small further with a fluid level only adjacent to a lower surface of an upper disk 3 of non-magnetic material, even when the upper disk 3 is rotated by an input shaft 1, rotational torque is not transmitted to a lower disk 4 of magnetic material and a tubular member 7, and an output shaft 2 maintains a stationary condition. When the magnetic fluid 12, lower disk 4 and a cover unit 9 are magnetize by exciting the electromagnetic coil 15, the magnetic fluid brought into contact with the lower surface of the upper disk 3 is partly circulated into a space h2 between the cover unit 9 and the upper disk 3, and a cavity is formed in the central part of a space h1 between the upper/ lower disks 3, 4. In this way, shear stress of the magnetic fluid 12 in the space between the upper disk 3 and the cover unit 9 is increased to transmit rotational torque of the input shaft 1 to the output shaft 2.

Title: Method for calibrating intensity of x-rays in x-ray diffraction method
Inventor: NAKAYAMA MASAO
IPC: G01N23/207
Filed: 1999-10-20
Abstract: PROBLEM TO BE SOLVED: To calibrate the intensity of X-rays with high accuracy for a short time in quantitative analysis by an X-ray diffraction method using a monochromator. SOLUTION: In an X-ray diffraction method wherein a sample 2 is irradiated with X-rays emitted from an X-ray source 1 and the intensity of diffracted X-rays reflected from the sample is detected by a detector 3 through a monochromator 5, a standardized sample containing at least the same element as the target of the X-ray source 1 is used to calibrate the intensity of diffracted X-rays in order to perform the quantitative analysis of the sample 2. Since the standardized sample containing at least the same element as the target of the X-ray source 1 is used, fluorescent X-rays of which the kind is same to that of characteristc X-rays generated in the target are also generated from the standardized sample. The fluorescent X-rays are incident on the detector 3 as they are without being removed by the monochromator 5 to be detected as a background. Therefore, the intensity of X-rays of sufficient magnitude required in calibration can be obtained and can be calibrated with high accuracy for a short time.

Abstract: PURPOSE:To prevent the occurrence of salvage displacement of, by a method wherein, in an edge control device operated during winding of a vinyl sheet and the like, a vertical drive mechanism is mounted to both ends of the one roll of a roll pair, and is driven according to a salvage displacement signal. CONSTITUTION:When a sheet 1 from an extruder is wound around winding pipe, the sheet is fed from between first and second rolls 2 and 3. When the sheet is detected by means of a first detector 4a, second-fourth detectors 4b-4d are brought into a working state. With the second and third detectors 4b and 4c cut off, a motor 5a of a drive device 5 is not actuated, when only the second detector 4b is cut off, the motor is run forward, and when the second-fourth detector 4b-4d are cut off, the motor is reversed. For example, when the detectors 4b-4d are all cut off by means of the sheet 1, the motor 5a is reversed, the rightmost end of the roll 2 positioned facing the second roll 3 ordinarily with a slight gap therebetween is pressed. Meanwhile, when only the detector 4b is cut off, the motor is run forward to lift the rightmost end, the other end is pressed by using the third roll 14 serving as a fulcrum, and salvage displacement is corrected through rotation of a motor 8.
