Title: Stress induction type polarized wave maintaining optical fiber
Inventor: TAJIMA KATSUSUKE
IPC: G02B6/028
Filed: 1986-08-27
Abstract: PURPOSE:To hold linear polarized light stably against disturbance such as bending and temperature variation by applying a core which has a specific refractive index distribution to a polarized wave maintaining optical fiber and reducing abrupt stress variation caused on the boundary surface between a core and a clad. CONSTITUTION:There are two stress giving parts 3 formed on both sides of the core 1, which is circular; and the refractive index n(r) of the core 1 is as shown by an equation I, and 1<alpha<2 and 0.2%<DELTA<1.0%, where n1 is the refractive index in the center of the core and DELTA the difference in specific refractive index between the core 1 and clad 2. Then the core 1 with an alpha-power refractive index distribution at the time of the use of this polarized wave maintaining optical fiber is as shown in a figure A(a). In this case, alpha is set to 1-2 as shown in a figure (b) so as to remove deterioration in double refraction due to wire diameter variation at the time of the drawing of the optical fiber. Further, the difference DELTA in specific refractive index is set to 0.2-1.0% so as to reduce the loss due to the bending of the optical fiber. Deterioration due to crosstalk is eliminated by increasing the refractive index n3 of a stress inducing part 3 up to the refractive index n2 of the clad.

Title: Autofocusing device for camera
Inventor: SUGAWARA SABURO
IPC: G02B7/32
Filed: 1990-07-27
Abstract: PURPOSE:To decide the composition of objects and to take a correctly focused picture by measuring a distance to the object positioned at the shortest distance from a camera and deciding the movement quantity of a photographing lens from the result of measurement. CONSTITUTION:Distance information corresponding to the object positioned at the shortest distance is stored based on light receiving outputs along the base line length direction of a light receiving and the photographing lens is focused on the object based on the stored information. Namely, it is assumed that an object X is positioned the nearest to the camera, an object Z is positioned further than the object X from the camera, and the object Y is positioned in the middle of the objects X and Y. Assuming that the objects X-Z are properly separated in a horizontal direction, reflecting light from the object X is received by a photodetector 6c, that from the object Y is received by a photodetector 6b, and that from the object Z is received by a photodetector 6a. At this time, only an output terminal 25 becomes at a high level, and the photographing lens 10 is delivered by a lens driving part 13 by a second delivering quantity corresponding to the photodetector 6c. Thus, a well focused picture can be always taken regardless of the comparative positional relation of a main object to the remaining objects.
