Title: Improved changeover-type reluctance speed sensor
Inventor: JIEEMUZU DEII SHIIFUERUTO
IPC: G01D5/245
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To provide an improved changeover-type reluctance wheel speed sensor. SOLUTION: A bearing assembly for a vehicle comprises a ring-shaped sensor 10 which is connected to one out of a fixed element and a rotating element. The sensor 10 contains a pickup coil and a ring-shaped magnet 86 comprising a plurality of magnetic regions which are connected to the pickup coil and whose polarities are changed over. The magnet 86 generates a magnetic flux path by which the magnet itself is coupled magnetically to the coil. As a result, an electric signal is generated in the coil. Gear teeth which are contained in the rotating element change the reluctance of the magnetic flux path, the electric signal is changed so as to respond to the angular velocity of the fixed element with reference to the rotating element.

Title: Optical fiber with altering diameter
Inventor: KAWAI YOSHIO
IPC: G02B6/00
Filed: 1993-12-14
Abstract: PURPOSE:To effectively utilize the quantity of the light of a light source lamp so as to make the use of a highly sensitive detector unnecessary for fluorescent light measurement by making light from a light source enter into an optical fiber, and narrowing the diameter of the optical fiber itself. CONSTITUTION:The cross-section surface area on one side of an optical fiber 5 is made to be four times wide or more than that on the other side and the altering rate of the diameter is made to be smaller than the number of open parts (numerical apertures) determined based on the composing materials of the fiber. Except the light absorbed in the fiber and the light lost by radiation from the fiber wall, the light made to enter into the optical fiber 5 is radiated from the outlet of the optical fiber. When the diameter of the fiber is lessened to a half, the quantity of the light absorbed in the optical fiber is increased at maximum to four times of that per the same length provided that the absorbed light quantity is proportional to the intensity of light per unit area and the absorptivity is as low as several DB/km and can be neglected. The radiation loss from the fiber wall can be suppressed to be at most several % when the lessening ratio of the diameter is smaller than the angle determined based on the number of apertures.
