Title: Optical isolator
Inventor: KAMATA OSAMU
IPC: G02B27/28
Filed: 1987-09-22
Abstract: PURPOSE:To form an optical isolator having a high isolation ratio with a low cost and a good yield by arranging a magneto-optical element between a polarizer and an analyzer and providing a total reflection mirror of one end face of the analyzer. CONSTITUTION:Transmission and polarization directions of a polarizer 1 are made different by 45 deg., and a magneto-optical element 3 which has 45 deg. Farady rotation by a magnet 4 is arranged between the polarizer 1 and an analyzer 2, and a total reflection mirror 5 is provided on one end face of the analyzer 2. An incident light L1 is converted to a linearly polarized light by the polarizer and is rotated at 45 deg. by the optical element 3 and is transmitted through the analyzer 2 and is reflected on the total reflection mirror 5 and is converted to a transmitted light L2 by the polarizer 1 and is emitted. A return light L3 is rotated at 45 deg. by the element 3 and is made incident on the analyzer 2, and this light becomes a loss light L5 on the outside of the optical path because its polarization direction is orthogonal to the polarization direction of the light transmitted to the reflection mirror 5. Thus, the optical isolator having a high isolation ratio is formed with a low cost and a good yield.

Abstract: PURPOSE: To simplify a structure with a pressurizing tank eliminated, and also reduce the occurrence of corrosion by adapting oilless bearings for the respective sliding sections of a runner vane operation means within a runner boss, and letting a runner corn covering the tip end of the runner boss be equipped with a screen provided with transmission holes. CONSTITUTION: Each oilless bearing is adapted for respective sliding sections, such as a runner boss bush 4, runner vane stem bushes 5 and 6, a cross head guide bush, a cross head guide sliding piece, and a link pin bush. And let each section faced to the oilless bearings be made of stainless steel or hard chrome plated material and the like for lubrication and corrosion prevention. Besides, the tip end of a runner corn 3 is provided with a screen 21 having a great number of transmission holes small in diameter each, through which river water freely comes in and out. Since river water thereby freely comes in and out of a runner boss 2, the inside of the runner boss 2 is naturally kept identical in pressure to its circumference. Since the inside of the runner boss 2 is filled with river water, corrosion due to oxidation seldom occurs.

Title: Ion implantation device
Inventor: SUGIMOTO RIKAO
IPC: H01J37/147
Filed: 1992-08-17
Abstract: PURPOSE:To eliminate need of a deflection electrode on the grounding side and a power supply for it, and reduce a device cost by providing a first and a second deflection electrodes between a mass analysis magnet and an acceleration tube, and setting an ion beam in a horizontal direction to be introduced into the acceleration tube. CONSTITUTION:An ion beam introduced out of a mass analysis magnet and deflected by a first deflection electrode 5' by a specified angle is deflected again to be horizontal by a second deflection electrode 14 provided in a vacuum chamber 4'' to be introduced into an ion acceleration tube 3. Need of a deflection electrode conventionally provided on the grounding side and a power supply to supply a voltage to it is thus eliminated. The electrode 14 exists upstream of the acceleration tube 3 to deflect ions before they are accelerated, so a length of the whole body of a device can be much shorter than that of conventional devices. Selection of standards in assembling the whole body of the device including the acceleration tube becomes easy, and thereby the device cost can be reduced largely.
