Title: Polarization controller
Inventor: ODA HITOSHI
IPC: H04B10/25
Filed: 1992-12-18
Abstract: PURPOSE:To produce a polarization controller with only one magneto-optical material or element and with simple constitution by using a Cotton-Mouton effect. CONSTITUTION:An arbitrary polarized state can be converted to a known polarized state (for example, linear polarization) by using only one magneto-optical material or element by using the Cotton-Mouton effect that is one of magneto- optical effects. In other words, a cylindrical magneto-optical material or element 1 is arranged in electromagnetic coils 2, 3 which generate two pairs of transverse magnetic fields in a plane perpendicular to the longitudinal axis. The size of magnetization M and an angle (phi) in the plane perpendicular to the advancing direction of light can be controlled by changing a current on the two pairs of electromagnetic coils 2, 3 intersecting orthogonally to each other, and incident light whose polarized state is unknown is converted to arbitrary prescribed polarized light. Therefore, only electric control can be applied, and no mechanical driving is required, which enables simple constitution to be taken by employing such constitution.

Abstract: PROBLEM TO BE SOLVED: To provide a method of estimating the deterioration of the lubricating oil capable of estimating the deterioration stage after supplying the lubricating oil and a method of supplying and improving the service life of the lubricating oil capable of determining the supplying condition so as to restrict the deterioration to a certain degree by grasping the lubricating oil supplying condition. SOLUTION: Deterioration speed of the dynamic viscosity of the lubricating oil under the real operating condition is previously obtained, and thereafter, dynamic viscosity of the lubricating oil is measured, and the dynamic viscosity after a certain time is passed from the measurement time is computed on the basis of the deterioration speed, and the supply ratio and the supply interval in the case of supplying the new oil to the lubricating oil are determined so as to estimate the deterioration of the lubricating oil after the supply. Deterioration stage of the lubricating oil can be estimated by setting the supply ratio and the supply interval of the new oil.  Since the deterioration stage of the lubricating oil is saturated by controlling the supply ratio and the supply interval of the new oil, the lubricating oil can be used for a long time while maintaining that deterioration stage, and service life can be improved. Furthermore, the lubricating oil can be used in the high temperature environment higher than the ordinary use temperature by satisfying the predetermined supply ratio and the supply interval.
