Title: Sound reproducing device
Inventor: TANAKA SHINICHI
IPC: G10L21/043
Filed: 1991-08-01
Abstract: PURPOSE:To absobe the interval change of a reproduced sound caused by an unevenness of rotation while the device is small in size and light in weight and to drastically improve the sound quality of the sound reproducing device. CONSTITUTION:A change in the rotational speed of a motor is detected and transformed to an electric signal. Then, a sound signal read out of a tape 22 is not reproduced as it is, temporalily digitized by a voice recording/reproducing LSI 24 and stored in a memory 25. Digital data in the memory is returned to an analog sound signal by a sound recording/reproducing LSI 26 and reproduced from a speaker 27 as a sound. When the change of the rotational speed is detected by the detecting means, it means that the interval of the read-out sound signal is changed. The sound signal having a different interval is digitized and stored in the memory 25. Then at the time of reproducing, the sound signal is returned to original interval by changing the reading-out speed of digital data read out from the memory 25 by the sound recording/reproducing LSI 26.

Title: Magnet apparatus for mri
Inventor: ARAKI TAKAHISA
IPC: G01R33/383
Filed: 1990-07-25
Abstract: PURPOSE:To allow no adverse effect on an output image of an MRI apparatus by forming a magnet apparatus from a plate-shaped insulation magnetic pole member with magnetic pole pieces thereof so arranged as to make a thickness- wise direction thereof vertical to a direction of a magnetic field. CONSTITUTION:A pulse-like magnetic field (b) is applied to a magnet apparatus 10 for MRI from a gradient magnetic field coil. As a result, the pulse-like magnetic fields (b) hit silicon steel plates 12a, 12b... in a direction the same as the direction of a magnetic field B and normally, an eddy current flows vertical to the direction of the magnetic field B. But as the silicon steel plates 12a, 12b... are treated to insulate, a flow of the eddy current is prevented on a magnetic pole piece 12 by the pulse-like magnetic fields from the gradient magnetic coil. This also prevents the generation of a magnetic field otherwise generated eventually. The magnet apparatus for MRI thus obtained allows no adverse effect on an output image of an MRI apparatus.
