Title: Image transmitting optical fiber array, waveguide image transmitting array and processing method for edge thereof
Inventor: RII EMU KUTSUKU
IPC: G02B6/06
Filed: 1993-03-17
Abstract: PURPOSE: To improve image contrast by absorbing incident radiocative rays without secondary discharge so as to make the cladding exposing part of the tip part of an array nearly translucent. CONSTITUTION: A waveguide array in the shape of an optical fiber surface plate 20 consists of plural optical waveguides with the core 21 of a glass phase and cladding glass 22. The incident radiocative rays toward the cladding glass 22 are absorbed without generating secondary discharge to make an exposing surface 24 nearly translucent with respect to the incident radiocative rays. Desirably, the cladding glass 22 includes reductive cations such as lead, bismuth, arsenic, tin or their mixture. Then, an opaque surface layer 23 is selectively formed by exposure to a reducing condition on the external exposed surface 24 of the cladding glass 22. Thereby incident light 28 hitting a layer 23 covering the cladding glass 22 is absorbed and is prevented from entering the cladding glass 22. Consequently, substantially very small amount of crosstalk to the fiber is removed from the fiber.

Abstract: PROBLEM TO BE SOLVED: To attain high reliability by forming the shaft of a fluid bearing shaft with a magnetized fluid bearing brushless motor. SOLUTION: This motor is a radial type brushless motor, and when a coil is energized, magnetic fields are generated around the salient pole of a stator core 9. Torque is generated between a driving magnet 12 for magnetic field facing a stator core 9 and it, and a magnetic disc rotates with a rotor hub 1. When a shaft 14 rotates, lubrication fluid is pumped by action of a herringbone groove formed at the cylindrical parts 15, 16 of a sleeve 2, so that the shaft 14 floats and rotates with no-contact. The lubrication fluid is conductive oil. The shaft 14 and a housing 3 is in a conductive condition even during its rotation and, therefore, the magnetic disc and a device chassis becomes in an conductive condition. It is thus possible to electrify the magnetic disc with static electricity and prevent generation of a potential difference between the magnetic disc and the magnetic head.
