Title: Measuring instrument of film thickness
Inventor: MORI MIKIO
IPC: G01B11/06
Filed: 1985-02-08
Abstract: PURPOSE:To measure film thickness highly accurately and highly rapidly by arranging an ellipsometer and an interference gauge in one device body. CONSTITUTION:A refractive index on one point P of a thin film of a semiconductor wafer 5 is detected by the ellipsometer to form a film thickness list. The film thickness list is obtained by sampling the film thickness values periodically outputted and any one of the values is a required film thickness value. Then, the wavelength of interference light from one point P of the thin film of the wafer 5 is detected by the interference gauge 3. The wavelength found out by the interference gauge 3 is analyzed on the basis of the refractive index found out by the meter 2 to calculate the film thickness on one point P of the thin film of the wafer 5. Then, the film thickness data are fed back to the meter 2 and a value most close to the film thickness data is selected out of the values in the film thickness list previously calculated by the meter 2 to determine the film thickness. Consequently, the film thickness can be measured rapidly with high accuracy.

Abstract: PURPOSE: To enhance the strength of a cylinder tube as well as sink its manufacture cost by forming a cylinder tube in a solid molded construction through cold plastic processing.  
     CONSTITUTION: This cylinder tube 1 in a cylinder device is formed by cold plastic processing applied to a material tube of metal having a necessary wall thickness, to shape up it in different wall thicknesses according to the stress expected at respective tube portions, where the wall thickness of tube 1 on the bottom member 3 side is increased to obtain a thicker part 1b. The leg length for bevel angle at the part to be welded can be therefore chosen large for the time of inserting this thicker part 1b into the minor diameter part at the bottom member 3 and welding its end to this bottom member, so that the welding strength at this part can be raised up. At the head member 4 side, on the other hand, a thicker part 1a is formed, where the wall thickness is increased alike. The conventional requirement that a flange must be welded on cylinder tube 1 at the head member 4 side is eliminated thanks to this thicker part 1a, that assures simplified construction and reduced cost.

Title: Optical waveguide circuit with taper and its production
Inventor: OKUDA EIJI
IPC: G02B6/122
Filed: 1986-02-08
Abstract: PURPOSE:To execute prescribed optical processing such as reflection and transmission with high efficiency near the designed performance of an element by forming a refractive index gradient to be gradually reduced from the center to the periphery within a section on a waveguide and making transmitted light incident upon a prescribed function element at an expanded waveguide part. CONSTITUTION:Since the waveguide has the refractive index gradient within the section, light beams advancing in the waveguide repeat meandering like an approximate since curve. When respective light beams transmitted in an input path 21B are inputted to a taper path 22B, respective angles formed by respective light beams and the optical axis of the waveguide are gradually reduced in accordance with the advance of the light beams in the taper path 22B because the surface of the taper path is inclined so as to be gradually separated from the optical axis of the waveguide in the advancing direction, and at the incidence to an expanded path 23B, respective light beams become approximately parallel to the optical axis of the waveguide. Since the light beams are made incident upon a filter 12 under said state the spectral characteristics of the filter 12 are accurately formed to the whole transmitted beams and highly accurate wavelength dividing performance can be obtained as the whole branching circuit.
