Title: Supporting device for turbine nozzle chamber
Inventor: NISHIGUCHI TOMOHARU
IPC: F01D9/02
Filed: 1978-12-29
Abstract: PURPOSE: To device a method for not transmitting thrust power through an airtight ring to a horizontal flange part and making a flange part compact by a method wherein a nozzle chamber accommodated between upper-and-under casings is held by the upper casing.  
     CONSTITUTION: A nozzle chamber accommodated in a compartment limitted by upper-and-under casings 1, 2 is held by a plural number of hanger pins, with which the upper casing near a horizontal flange part is provided. The thrust power produced in a L-shaped airtight ring 11 by pressure difference between inside the main steam chamber 6 and outside of the nozzle chamber acts on one side to push down the nozzle chamber but said power is transmitted to the hanger pins 14 and the upper casing 1. Consequently the thrust power by the airtight chamber 11 is not entirely transmitted to the under casing 2 so that no power is produced to separate the horizontal flange part 12 uniting the upper-and-under casings.

Title: Interconnection forming method
Inventor: SATO JUNICHI
IPC: H01L21/28
Filed: 1989-06-28
Abstract: PURPOSE:To flatten a substrate highly accurately and to simplify an interconnec tion forming step by forming the side surface of an overgrowth part in an inverted tapered shape, applying a resist film so that the upper flat surface of the overgrowth part is exposed from the surface of the resist film, and remov ing the overgrowth part. CONSTITUTION:A contact hole 3 is opened in an interlayer insulating film 2 which is formed on a semiconductor substrate 1 or a lower wiring layer. A conductive material 1 is selectively grown on the contact hole 3 so that the side wall of an overgrowth part 5 is opened toward the upper side. A resist film 6 thinner than the overgrowth part 5 is formed on the substrate 1. Then, the overgrowth part 5 is removed. An upper wiring layer 7 is formed on the substrate 1 so as to cover the contact hole 3. Therefore, the conductive material 4 is exposed on the surface of the substrate 1 from the beginning. Since the overgrowth part 5 is selectively removed, the different material is not exposed on the surface of the substrate 1 in halfway, and the change in etching rate does not occur. In this way, the step for flattening the surface of the substrate 1 can be simplified, and the interconnection characterized by high reproducibility can be performed.

Title: Optical fiber connecting method
Inventor: NODA JIYUICHI
IPC: G02B6/24
Filed: 1982-09-22
Abstract: PURPOSE:To make a low polarization dispersed connection and a maximum polarization dispersed connection between optical fibers by emitting pulse light by using a semiconductor laser and using the pulse light. CONSTITUTION:Mode lock YAG laser light is used and inputted to an optical fiber and output light is sent to a detector. Then when the plane 18 of polarization of linear polarized pulse light is not coincide with the principal axis of the 1st optical fiber, two pulses 20 and 21 appear on a cathode-ray tube image 19 on a synchroscope. In this case, those pulse light 20 and pulse light 21 have a long and a short axis respectively. This is applied to a connection between polarization convervative optical fibers. For the low polarization dispersed connection, pulse light along the long axis of the core 1 of the 1st optical fiber 9 is matched with the short axis of the 2nd optical fiber, so the 2nd optical fiber 12 is rotated to extinguish pulse light 24. For the maximum polarization dispersed connection, on the other hand, the long axes of the two optical fibers are made coincident with each other, so the 2nd optical fiber 12 is only rotated so that pulse light 25 along the long axis is extinguished.
