Abstract: PURPOSE: To provide a drooping torque characteristic, by arranging axially directional grooves for changing a distribution of magnetic flux for the circumferential direction on the inner circumference of a cylinder and outer circumference of a rotor and adding the characteristic of an eddy current coupling that generates its current on the basis of a change of distribution of magnetic flux.  
     CONSTITUTION: On the inner circumference of a cylinder 8 and outer circumference of a rotor 11, axially directional grooves 13, 14 for changing a distribution of magnetic flux for the circumferential direction are arranged to enlarge the depth for the magnetic flux in the rotor 11 to intrude and increase a number of the magnetic flux passing through the part of the rotor groove 14. In this way, when a relative speed difference is developed between the cylinder 8 and the rotor 11, eddy currents according to said difference are generated on the both circumferential surfaces arranged in a face-to-face relation, and the distribution of magnetic flux density in its circumferential direction is as shown in the drawing. Accordingly, a clutch tends to show its characteristic in which the drooping torque characteristic of an eddy current coupling is overlapped on the constant torque characteristic as a powder clutch, finally a compound torque characteristic of the both kinds of clutch characteristic, that is, the drooping torque characteristic as shown by If 1 , If 2  in the drawing can be obtained.

Title: Energy diffusion signal elimination circuit
Inventor: TOMIYA OSAMU
IPC: H04J13/00
Filed: 1991-03-26
Abstract: PURPOSE:To automatically eliminate a chopping wave signal even when the amplitude and cycle of the chopping wave signal superimposed to a MUSE signal is changed for each channel. CONSTITUTION:An A/D conversion circuit 1 digitally converting the MUSE signal is connected to a level difference detection circuit 15, and the level difference of an HD point for each line is outputted with + or - code. A code inversion detection circuit 13 outputs an inversion detection signal to an amplitude detection circuit 19 when the level difference code is inverted. A level difference addition circuit 23 adds the level difference signal from a line buffer 11 successively. The amplitude detection circuit 19 outputs the addition result at the input point of the inversion detection circuit as the level signal of the chopping wave signal. An inverse chopping wave formation circuit 31 outputs the inverse chopping wave signal whose level is adjusted by the level signal. An addition circuit 33 eliminates the chopping wave signal by adding the inverse chopping signal to the MUSE signal.

Title: Method and apparatus for diagnosing corrosion by ultrasonic wave
Inventor: TOMITA KIKUO
IPC: G01N29/04
Filed: 1987-04-08
Abstract: PURPOSE:To permit detection of the internal corrosion of a tank, etc., by projecting ultrasonic pulses to the tank, etc., from the outside thereof by a transmitting/receiving probe. CONSTITUTION:The ultrasonic waves repeat reflections between the inside and outside surfaces of the base material when the ultrasonic waves are projected to the measuring object 1 from the outside surface thereof by the transmitting/receiving probe. Multiple reflected echoes are then received by the transmitting/ receiving probe 3 and are observed by a data processor 4 and a display device 5. The change in the density of the base material and corrosion product is gentle with the part having internally the corrosion product or since the inside surface part is roughened, the reflectivity of the ultrasonic waves at the inside boundary face decreases and the irregular reflections arise at the inside boundary face, by which the damping factor of the reflection echoes is increased. The tank, piping, etc., with which the direct inspection of the internal corrosion condition by the naked dyes is not possible are thereby diagnosed from the outside of the pipe wall and the measuring object is diagnosed in the state under use on site.

Title: Pumping device
Inventor: TANAKA IKUYO
IPC: A61M1/10
Filed: 1992-04-07
Abstract: PURPOSE:To prevent pumping from being interrupted or stopped for a long period of time due to the abnormality of a pressure detection signal by detecting the abnormality of the detection signal of a pressure sensor, and increasing suction pressure at the change rate higher than the low change rate at the time of the pressure becoming less than the set pressure. CONSTITUTION:The output port pressure of a linear motor liquid pump 12 is detected by a pressure sensor 61. When the detected pressure is out of a first set range, the buildup speed of negative pressure is lowered to 1/2, and when the detected pressure is out of a second set range, the buildup of negative pressure is stopped. Monitor pulses are placed on the signal line of the pressure sensor 61 and counted during the initial suction period, and when the count value reaches the set value 51 or more, the pressure sensor system is judged to be abnormal. At the abnormal time of the pressure sensor system, the buildup of negative pressure is performed at the same speed as the steady time, disregarding the detection signal of the pressure sensor 61. The strong suction of living body tissue is thereby avoided, and the stop of suction caused by the intermixture of a wrong signal, the defect of a circuit, and the like can be prevented.
