Title: Axially asymmetric single mode optical fiber
Inventor: HOSAKA TOSHITO
IPC: G02B6/10
Filed: 1981-02-18
Abstract: PURPOSE:To provide a titled fiber of good single polarization holding characteristics by providing intermediate layers of coeffts. of thermal expansion differing from those of a core and clad only on both the opposite sides of the core between the core in the central part and the clad in an outer layer. CONSTITUTION:The section of a single polarization single mode optical fiber is shown, wherein the fiber is constituted of a core 1, a clad 2 and intermediate layers 3. The core 1 is circular, and the layers 3 are semicircular and exist only on both the opposite sides of the core 1. If SiO2+GeO2 is used for the material of the core 1, SiO2 for the material of the clad 2 and SiO2+P2O5+B2O3 for the material of the layers 3 and if the difference in refractive indices is set at 0.2%, the amt. of the GeO2 contained in the core 1 is slight, and the coefft. of thermal expansion thereof is roughly equal to that of the pure SiO2. Large residual tensile stress is generated in the X-axis direction where the layers 3 exist by the difference in the coefft. of thermal expansion between the core 1 and the layers 3 and therefore a large double refractive index with the core 1 part is produced, and the single mode optical fiber that can hold an off-centered state against the fluctuations to external conditions is obtained.

Inventor: KANAZAWA SHIYOU
IPC: F28D17/00
Filed: 1980-02-25
Abstract: PURPOSE: To produce continuously high and low temperatures for heating and cooling air-conditioned apparatus by connecting heat exchanger in reaction bathes for high and low temperature heat sources including different metals which store hydrogen with a heat exchanger in high and low temperature heat utilizing apparatus.  
     CONSTITUTION: By transferring the hydrogen in the low temperature heat reaction bath 5 to high temperature heat reaction bath 3 as the first reaction system, the hydrogen pressure in the reaction bath 5 is decresed. The temperature in the reaction bath 5 becomes low in correspondence with the equilibrium hydrogen temperature. On the contrary, the temperature in the reaction bath 3 becomes high as the high temperature metal 1 absorbs the hydrogen. Therefore, the high and low temperatures can be produced in utilizing apparatus 16, 18, respectively via heat exchangers 3C, 5C in each bathes 3, 5. At the same time, the reaction bath 4 for the second reaction system is heated by the external heat source 14 and the hydrogen is liberated. The preparation for the next reaction is arranged as the hydrogen is introduced into the low temperature metal 2 in the reaction bath 6 via tube 10. By switching the first and the second reaction systems, the high and low temperatures are produced continuously.
