Title: Deceleration controlling method of train
Inventor: FUJITA SHINICHIROU
IPC: B60L15/40
Filed: 1983-04-27
Abstract: PURPOSE:To reduce an average deceleration by extending a deceleration control target ground point at every prescribed distance from a ground point of control length toward a signal blocking zone end whenever a train runs at the prescribed distance in a signal blocking zone to obtain a deceleration. CONSTITUTION:When a train is decelerated from a traveling speed V0 to the prescribed traveling speed V1 in a signal blocking zone S, a deceleration beta1 is first calculated on the basis of a preset control length S0 (S0=KS, K<1), and applies a brake command corresponding thereto. Thus, the train operates a brake toward the imaginary stopping point L1 at the deceleration beta1. When the train advances at the prescribed distance (d), the deceleration control target ground point is calculated from the ground point of the control length S0 at the position before the blocking zone end at (1-K)d at the blocking zone end side, and the deceleration beta2 is calculated. Thereafter, the deceleration control target point is extended at every (1-K)d whenever the prescribed distance (d) is driven, and deceleration beta2-betai are calculated.

Title: Artificial intervertebral disk
Inventor: KANEDA KIYOSHI
IPC: A61F2/44
Filed: 1990-03-23
Abstract: PURPOSE:To provide flexibility capable of sufficiently following the motion of a human body by forming upper and lower columnar or square pillar-shaped regions of a composition prepared by dispersing and adding a living body-active ceramic powder in a polymer elastic material base having bio-compatibility and forming a central region only from a polymer elastic material. CONSTITUTION:The whole is molded into a columnar body 10 and the upper and lower regions A, B thereof are formed from a composition prepared by dispersing and adding a living body active ceramic powder 12 in a polymer elastic material 11 having bio-compatibility and the central region C thereof is formed only from the above-mentioned polymer elastic material 11. Therefore, when the upper and lower end surfaces of this artificial intervertebral disk are bonded to the vertebral bodies of a living body, the living body-active ceramic powder dispersed and contained in the regions A, B is chemically and integrally bonded to the vertebral bodies of a living body. Since the intermediate region part of the artificial intervertebral disk is constituted only of the polymer elastic material and has elasticity, the upper and lower ceramics-containing regions freely revolve around the intermediate region part by a certain degree move flexible and thereby the whole of the spine smoothly moves and no unreasonable load is applied.

Title: Pickup for magneto-optical recording medium
Inventor: SUNAKAWA HIROSHI
IPC: G11B11/10
Filed: 1989-03-27
Abstract: PURPOSE:To improve accuracy for signal reading and error detection and to reduce energy consumption by reflecting the polarized component of a reflected beam, which is not made incident to a first optical waveguide, and making the component incident to a second optical waveguide. CONSTITUTION:Since a first optical waveguide 22 and a second optical waveguide 29 are mutually formed in separate bodies, the patterns of condensed diffraction gratings FGC 31 and 32 in one optical waveguide side, for example, in the side of the first optical waveguide 22, are moved to the other optical waveguide 29 side and not remained. Since it is not necessary to make a glass substrate between the both optical waveguides 22 and 29, an optical detector is easily prepared. The polarized component not to be made incident to the waveguide 22 by the FGCs 31 and 32 on the surface of the waveguide 22 is made incident to the waveguide 29 by an FGC 33 on a surface 29a of the waveguide 29. Thus, in comparison with a case that the plural FGCs are parallelly provided in one optical waveguide and irradiated with the beam reflected from a magneto-optical recording medium, the detecting efficiency, namely, the optical using efficiency of the reflected beam can be improved.
