Title: Magnetic resonance imaging device
Inventor: ITAGAKI HIROYUKI
IPC: G01N33/48
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging device capable of surely and accurately extracting an activation area even if a mismatch has occurred between the period of subjective stimulus application in which a subject feels the application of stimuli and the period of actual stimulus application. SOLUTION: First, time-series image data consisting of the measurements of brain functions are subjected to Fourier transform in the direction of a time axis to calculate the frequency spectra of changes in signal (1-6) and to arrange calculation results on a twodimensional graph whose coordinate axes are spectrum width and phase difference near a frequency 0 (7-8). Next, similar processes are effected for a function showing stimulus application/stop (9-13). Finally, the relative positions of the data points of a time-series image on the two-dimensional graph and the data points of the function showing stimulus application/ stop are judged to eliminate the data points constituting noises while extracting an activation area (14-15).

Title: Polarized electromagnet device
Inventor: TANAKA KOJI
IPC: H01F7/14
Filed: 1987-02-24
Abstract: PURPOSE:To facilitate making the title device into a single staple and to obtain excel lent operability and vibration resistance in a polarized electromagnet device by increas ing the number of windings of a coil on the attraction side at the time of operating larger than that of a coil on the opposite attraction side at the time of recovery. CONSTITUTION:A magnetic path of a magnetic flux phic which passes the left side leg 1a of a core, by a permanent magnet 2 is formed in addition to an exciting mag netic flux phiB in the exciting state of a coil 3. Accordingly, the left end 4a of a mov able iron piece 4 is attracted to be held to the end 1d of the left side leg 1a of the core 1. Further, the number Na of windings of a left side coil section 3a of the coil 3 is set larger than the number Nb of the right side coil section 3b. Therefore, the magnetic flux phiB which passes the right side leg 1b of the core 1 merely cancels the magnetic flux phiA of the magnet 2, while the magnetic flux phiB which passes the left side leg 1a of the core 1 operates to largely contribute to the attraction of the left end 4a of the piece 4. Thus, the attraction force is increased, the adjustment of the operating characteristics in case making it of a single staple is facilitated, and the operation of the piece is accelerated, thereby obtaining excellent vibration resistance in the operating state.

Abstract: PURPOSE: To attain utilization for the adjustment of a decision level by obtaining decision information from the frequency component of a digital signal obtained by separating a certain signal into 0 or 1 on the basis of a decision level by using a signal separating circuit.  
     CONSTITUTION: Comparator 9' included in signal separating circuit 9 separates a reproduced signal into 0 or 1 by making decision on its magnitude on the basis of decision level E to output signal S. This separated signal is input to tuning transformer T 1  via capacitor C 1 , etc. A tuning circuit is so constituted that the primary side of this transformer T 1  and capacitor C 2  will tune to transfer rate frequency fT. A component of transfer rate frequency fT obtained at the secondary side of this transformer T 1  is amplified and rectified to charge capacitor C 4 . A voltage across resistance R 7  connected in parallel to capacitor C 4  is small as the data transfer rate frequency component of separate signal S is small and minimized when the decision level reaches the best decision level. Therefore, information regarding the best decision level can be obtained and used effectively for the decision level adjustment.

Title: Multiple wavelength spectrophotometer
Inventor: SEKIWA MITSUNAO
IPC: G01J3/04
Filed: 1985-03-04
Abstract: PURPOSE:To suppress error generation and to reduce the time necessary for light measurement by so arranging that two members having a light transmitting part transmitting the light corresponding to the wavelengths of the dispersed light are connected for relative rotation and concentrically relative to each other to form a light outgoing slit. CONSTITUTION:The light from a light source radiated on a grating 5 through a lens 2, a low frequency cut-off filter 3 and an incident slit 4 is radiated on a light outgoing slit 6 with prescribed scattering. Only the light corresponding to the slit 6 of the dispersed light is passed and radiated to a photomultiplier 81 through a spectrral sensitivity correcting plate 11, a h igh order light cut-off filter 12 and a lens 13 so that only the light of the wavelength corresponding to the slit position is measured by a photodetector 8. Therefore, when an outgo ing slit drive part 7 is caused to drive the slit 6 not liable to produce vibrations due to lightness in weight, the wavelength irradiated on the photodetector 8 is changed and, by relatively rotating two members making up the outgoing slit 6, the extent of the light transmitting part can be changed for changing the transmitted light volume.

Abstract: PROBLEM TO BE SOLVED: To reduce the rotational torque of a bearing by projecting a projected part which is projected in the inner diameter direction from a pocket end face located close to the outer diameter of an annular body and brought into contact with an end face on the outer circumferential side of a roller. SOLUTION: A holder 1 is provided with a projected part 5 in which a roller 9 is arranged in each pocket 7 of an annular body 2, and which is provided between upper and lower races, projected in the inner diameter direction from a pocket end face 8 close to the outer diameter 3 of the annular body 2, and brought into contact with the end face 10 on the outer circumferential side of the roller 9. The projected part 5 is thin-walled so as not to cause any troubles in a roller guide, and large in the curvature of the curve, and the contact with the roller 9 is preferably in the vicinity of the center. When the bearing is turned, the roller 9 is pressed against the outer diameter side by the centrifugal force, and turned, and a tip 6 of the projected part 5 is brought into contact with the roller 9 in the vicinity of the center thereof.  Thus, the rotational torque of the roller 9 is suppressed small, and the wear of the pocket 7 is also suppressed small because the peripheral velocity by the rotation is small in the vicinity of the center of rotation.
