Title: Optical fiber magnetic field sensor
Inventor: SHIODA TAKAO
IPC: G02F1/01
Filed: 1985-12-12
Abstract: PURPOSE:To detect the intensity of a magnetic field accurately by detecting the disturbance of an optical fiber originating from vibrations, temperature, etc., through the 2nd optical fiber arranged along the 1st optional fiber on a sensor side for the magnetic field and removing the disturbance. CONSTITUTION:Light emitting and receiving parts 13 and 14 and the magnetic field sensor part 11 are separated and coupled by the 1st optical fiber 9, and the 2nd optical fiber 18 of the same length is arranged along the 1st optical fiber 9; and the disturbance due to temperature, vibrations, etc., that the 2nd optical fiber 18 receives is detected and removed from the detected value of the magnetic field sensor 11 by a computing element 24. Consequently, the intensity of the magnetic field is detected accurately without being affected by the vibrations, temperature, etc., of an optical fiber magnetic field sensor which detects the intensity of the magnetic field by detecting a shift in phase due to the magnetostrictive effect of the optical fibers.

Abstract: PURPOSE:To prevent the generation of unqueal image densities by providing soft elastic ring members between both ends of a sleeve roller and a driving roller and elastically supporting the slackening parts at both ends of the sleeve roller from the inner side of the sleeve roller. CONSTITUTION:The rings 31, 31 made of foamed polyurethane having soft elasticity are fitted to both ends of the shaft 12 of the driving roller, i.e. parts facing the inner periphery at both ends of the sleeve roller 2. Pressing belts B press the sleeve roller while compressing the rings 31 until the sleeve roller 2 comes into contact with the surface of the foamed silicone layer 11 of the driving roller 1. As a result, the sleeve roller is formed with the slackening parts 20 on the outer side of a casing and the inner side of the slackening parts at both ends of the roller is filled by a part of the elastic rings 31 which are so elastically reset to fill the spacings thereof. The slackening parts are thus elastically supported from the inner side. The nip width generated by contact of both ends of the sleeve roller having small lateral rigidity and the easy tendency to deformation with a photosensitive body PC is uniformly stabi lized over the entire part of the roller in this way and the generation of the unequal image densities is prevented.

Abstract: PURPOSE:To reduce current drift stably by extending the region, where the concentration of phosphorus is set at a specified level or below, over a distance equal to one half of the thickness of a magnetosensitive layer or more from the surface of the magnetosensitive layer toward the heterojunction with InP. CONSTITUTION:An undoped InP butter layer 102 is deposited on a semiinsulating InP single crystal substrate 101 doped with Fe. Upon growth of the InP buffer layer 102, supply of PH3 gas and In is interrupted and only hydrogen carrier gas is fed for 2min after interruption of PH3 gas. After that, supply of AsH3 and In is resumed thus growing Ga0.47n0.53As magnetosensitive layer by 400nm. Since a 2min pause is provided in order to lower the PH3 concentration sufficiently, concentration of phosphorus in the GaInAs layer can be lowered to 10<15>cm<-3> or below. The thickness of film having that phosphorus concentration is 280 nm I from the surface which equals to 50% or more of the thickness of GaInAs magnetosensitive layer 103. Consequently, current drift can be reduced within + or -15%.
