摘要： PROBLEM TO BE SOLVED: To solve such problems that a rolling stock is required to be stopped for the purpose of measurement to worsen the working efficiency in a conventional wheel weight measuring instrument, and that an instrument price is high because four load cells are used for the measurement of the weight of one wheel in the conventional wheel weight measuring instrument. SOLUTION: In this instrument capable of measuring wheel weight during travel, the wheel weight under the travel is measured from the advance of the wheel to a measuring rail up to the retreat thereof using one load cell by supporting the measuring rail capable of measuring the wheel weight during the travel with a linear guide, and a wheel weight value is calculated by least square.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive and safe sliding door. SOLUTION: A recessed part 23 is formed at the outer peripheral end part of window glass 20 installed in the sliding door 10 on the side surface of a rolling stock. The recessed part 23 is located on the inside of the rolling stock. An end part on the outside of the rolling stock is formed in a projected piece 21b. The piece 2b is inserted into an H rubber 30. The projected pieces 11b and 12b on the inner peripheral surface of the sliding door 10 are inserted into the H rubber 30. The surface of the H rubber 30 on the inside of the rolling stock is continued linearly from the window glass 20 to the surface of the H rubber on the inside of the thick portion of the sliding door 10. A wedge- shaped rubber 42 is disposed in the recessed part between the inner peripheral end of the H rubber 30 and the thick portion of the window glass 20. The outer peripheral end part of the H rubber 30 comes into contact with the slanted part 11c of the sliding door. Thus a step and a recessed part can be eliminated.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive branching device for monorail. SOLUTION: This device comprises connecting plates 31 on both side surfaces of the connection part of branching girders 4 and 3. One-side ends of the connecting plates 31 for traveling the guide wheel and stable wheel of a monorail vehicle are connected to the girder 3 by pins 33. The other ends thereof are also connected by pins 35, and the brackets thereof are elliptic. The connecting plate 31i located on the circular inner side between the pin 33 and the pin 35 is connected through a link 37 to bend the connecting plate 31i inward. The connecting plate 31o located on the circular outer side is pressed by a roller 39 from the girder 3 to the circular outer side. Accordingly, the traveling surface of the connection part of the girders 3 and 4 is made circular, so that the deterioration in comfortableness can be prevented.

摘要： PROBLEM TO BE SOLVED: To accurately measure actual thickness of a processed layer on line in plasma processing, specially plasma etching processing. SOLUTION: A standard pattern, which uses wavelength as a parameter, for a derivative value of an interference beam to predetermined film thickness of a first processed material is set. Intensity of an interference beam for a second processed material with the same structure as the first material is individually measured on a plurality of wavelengths, and an actual pattern, which uses wavelength as a parameter, for a derivative value of the intensity of the measured interference beam is determined. The film thickness of the second processed material is determined based on the standard pattern and actual pattern of the derivative value.

摘要： PROBLEM TO BE SOLVED: To simplify the costitution at the time of surface treating operation by introducing ozone into an airtight space formed at the inside of a treating system in a state same is assembled and passivating the inner surface of the airtight space. SOLUTION: After the completion of the assembly of a semiconductor fabrication system 1, the pressure in an airtight space is reduced, and, after that, high concentration ozone is introduced from a gas introducing tube 3. Ozone reaches a regulator 4, a valve 5, a mass flow controller 6 and a filter 7 together with a reaction chamber 8. At this time, the parts of joints 12b and 12c have been sealed by plugs or the like. Moreover, exhaust piping 9 in the reaction chamber 8 is sealed by a valve 11, ozone is charged thereto till the pressure reaches the atmospheric one, is sealed therein for a fixed time and is thereafter exhausted. Successively, such pressure reduction and charging operations are repeated, e.g. for three times. In this way, an oxidized film is deposited over the whole face of the inner surface of the system including details or the like of purchased parts in the gross, and by the oxidized film, the corrosion of the piping or the like caused by corrosive gas and plasma is prevented.
