Title: Reinforcing method of optical fiber fusion-connected part
Inventor: KASHIMA GIYUU
IPC: G02B6/24
Filed: 1978-11-21
Abstract: PURPOSE:To perform reinforcement of good workability and reliability within a short time by heating and reinforcing the fusion-connected part of optical fibers. CONSTITUTION:When a covering 2 is coated to the bar portion near the fusion- connected part of optical fibers 1, 1 and heat is applied thereto, the covering 2 dries instantaneously and the portion near the connected part 4 is reinforced with good workability in a short time. This provides the reinforcement of high reliability because no adhesive agents are used. If the adhesive part 4 is contained in a heat- resistant case 6 and is heated, the case 6 becomes reinforcement material owing to melting of the secondary covering 3. It is also possible to reinforce the connected part 4 by forming a protecting layer 7 through heating of the case of the same material as the covering 3.

Title: Rotation speed sensor
Inventor: SATO TOSHIRO
IPC: G01P3/487
Filed: 1992-06-03
Abstract: PURPOSE:To obtain a compact, light-weight, highly reliable and inexpensive sensor by constituting an inductance device of a soft magnetic body formed at a flat end surface of a rotary shaft and having the magnetic anisotropy, and a coil fixed to confront the soft magnetic body. CONSTITUTION:A soft magnetic body 2 having the magnetic anisotropy is formed at a flat surface of an end part of a rotary shaft 1 of a rotary apparatus. Moreover, a flat coil 4 is fixed at a fixed part 3 facing the end part of the rotary shaft 1 to confront the soft magnetic body 2. The soft magnetic body 2 and the coil 4 constitute an inductance. The soft magnetic body 2 is preferable to have small magnetostriction. When the easy axis of magnetization of the soft magnetic body is rotated in accordance with the rotation of the rotary shaft 1 to feed a current to the coil 4, a magnetic field orthogonal to the longitudinal direction of the coil is generated. The magnetic permeability of the soft magnetic body 2 seen from the coil 4 is changed by the rotating angle of the rotary shaft 1. Therefore, as the inductance between the terminals of the coil 4 is changed by the rotating angle of the rotary shaft 1, the change is measured to detect the rotating frequency.

Inventor: FUJIKI MICHIYA
IPC: C04B35/45
Filed: 1987-06-08
Abstract: PURPOSE:To obtain a superconductor consisting of metallic oxides capable of homogeneously mixing and sintering at low temperatures, by mixing salts consisting of cations of three specific metallic element groups and oxidizing anions and firing the resultant mixture. CONSTITUTION:A superconductor expressed by the formula is produced as follows. That is salts of cations of M1, M2 and M3 and oxidizing anions are mixed to form a mixture of metallic salts. The above-mentioned mixture is then heat-treated in an oxygen or oxygen-free atmosphere to provide a superconductor consisting of the metallic oxides. In the process, heating can be carried out fro improving mixing effects of molten salts or sufficiently advancing the reaction. Oxidizing anions having the ability to generate oxygen itself or oxidizing ability to enhance action of bonding to oxygen in air are used as the afore- mentioned oxidizing anions. Ions containing a halogen and oxygen are used in an amount of >=5% by weight ratio to especially effectively complete formation of the metallic oxides at a relatively low temperature and the aimed superconductor having a high superconductivity transition point is obtained.
