Title: Magneto-optical reproducing head
Inventor: MIYAUCHI SADAICHI
IPC: G11B11/105
Filed: 1988-04-22
Abstract: PURPOSE:To obtain a reproducing signal of large signal level even in the case of narrow track width by changing the change of the magnetization of a magnetic yoke into the change of the size of light and making it into the reproducing signal of a recording medium by the magneto-optical effect of the magnetic yoke. CONSTITUTION:At the time of reproducing, a signal magnetic field from the recording medium is led in a magnetic yoke 6 and the magnetization of the yoke 6 changes in accordance with the signal magnetic field. On the other hand, light from a laser diode 8 enters an optical waveguide path 7 and is polarized by a mode filter 12. This linearly polarized light is multiply reflected on the border of the yoke in an area just under the yoke 6 and the rotation of polarization plane by Kerr effect occurs. By repeating the multiple reflection, a Kerr rotation angle becomes larger to a size which can be detected as a signal. Polarized light which passes through the yoke 6 enter a photodetector 9 through a mode filter 13 and a reproducing signal is taken out. Thus, even in the case of the narrow track width, the reproducing signal of the large signal level can be obtained.

Filed: 1987-04-24
Abstract: PURPOSE:To obtain a bed apparatus not imparting any feeling of incompatibility to an examinee, by mounting a rail to a bed frame along a horizontal direction and mounting the roller capable of rolling on the rail to the bottom part of a holder. CONSTITUTION:An examinee is laid down on a top plate 4 through the elastomer covering the curved part 5a of a holder 5 and receives the injection of a contrast medium in such a state that the arm thereof is supported on the flat part 5b of the holder 5. When the examinee is moved by the top plate 4, since the top plate 4 and the holder 5 move on a rail through the rollers 3 amounted to the flat part 5b, the load due to the wt. of the examinee is applied to the rollers 3 and, therefore, said load is not concentrated to the holder 5. Because of this, even when the holder 5 is constituted of a thin material, there is no possibility of damage and a feeling of incompatibility is not imparted to the examinee. Further, since the holder 5 regularly and reciprocally moves on the rail 2 of a bed frame 1 through the rollers 3, the possibility of the interference of the holder 5 with the bed frame 1 is eliminated when the holder 5 moves along with the top plate 4 and the movement of the examinee can be smoothly performed.

Title: Objective lens driving device
Inventor: MATSUNO TOSHIKI
IPC: G02B7/28
Filed: 1983-06-03
Abstract: PURPOSE:To attenuate quickly the free oscillation in the tracking direction of a movable part by connecting a switch to a coil which drives an objective lens in the tracking direction and short-circuiting said coil with this switch when the objective lens in stopped suddenly. CONSTITUTION:When tracking control is broken and traverse is operated suddenly and is damped suddenly, an objective lens 1, a holder 2, and coils 3 and 4 of an objective lens driving device are oscillated freely in the tracking direction as one body. At this time, a driving coil 4 in the tracking direction is oscillated freely in the magnetic field made by a magnet 11. Since a switch 14 short-circuits the circuit between both ends of the driving coil 4 in the tracking direction simultaneously with the breaking of tracking control, a current is flowed by the generation of electricity due to relative oscillation of the driving coil 4 and the magnet 11. This current is converted to heat by the coil 4, and the kinetic energy of free oscillation is converted to a heat energy, and thus, the free oscillation is attenuated quickly.
