Title: Method for adjusting characteristic of optical waveguide circuit and optical waveguide circuit used in this method
Inventor: INOUE YASUYUKI
IPC: G02B6/34
Filed: 1990-07-09
Abstract: PURPOSE:To allow the exact adjustment of the coupling rate of an optical directional coupler and the optical path length of optical waveguides by applying heat to regions including the core parts of clad layers to generate a heat history, thereby changing the refractive index of the regions. CONSTITUTION:The effective refractive indices of the optical waveguides 1, 2 which are embedded in the clad layers 7, 8 or clad layer 7 disposed on, for example, a silicon substrate 9 and have the effect of propagating light are changed by utilizing the heat history of this material. The entire part of the optical waveguide circuit is subjected to a heating treatment in electric furnaces 41 to 45. The desired points of the optical waveguide circuit are otherwise subjected to the local heating treatment by the heat resistant heaters provided at the desired points on the optical waveguide circuit or irradiation with an energy beam. The heat history refers to a phenomenon that the refractive index value of the material of the clad layers 7, 8 or core parts 1, 2 of the optical waveguides 1, 2 varies with cooling conditions after heating to a high temp. The coupling rate of the directional coupler to be constituted in proximity to two pieces of the optical waveguides 1, 4 after the production of the optical waveguides is exactly adjusted in this way.

Title: Production of electrolytic copper foil
Inventor: OTA KAZUYOSHI
IPC: G01N21/21
Filed: 1994-07-08
Abstract: PURPOSE:To produce an electrolytic copper foil free from the discoloration of the glossy surface of the copper foil by detecting the change of degree of polarization of reflected light from the surface of a rotary drum of a cathode, on which the electrolytic copper foil is formed by electrodeposition, with an ellipsometer. CONSTITUTION:A circular-arcuate anode 22 is arranged to face to the cathode 21 composed of the titanium or chromium plated stainless steel-made rotary drum at a prescribed distance. The electrolysis is executed while allowing an electrolyte such as sulfuric acid copper sulfate solution to flow between both electrodes. The copper deposited on the surface of the cathode 21 by this way is stripped to continuously obtain the electrolytic copper foil 23. In the electrolytic copper foil continuous producing method, the change of the degree of polarization produced at the time of light reflection from the surface of the rotary drum 21, on which titanium or chromium oxide is formed, is measured by the ellipsometer. The change shows the activity of the oxidized film and by this method, the discoloration of the glossy surface of the obtained copper foil is detected beforehand.

Title: Cold/hot water fountain
Inventor: OTSU TOMONOBU
IPC: F25D11/00
Filed: 1990-07-06
Abstract: PURPOSE:To shorten the water delivery time by a method wherein a valve member is leaned on a hot-water inlet of a housing by the pressure of cold water and on a cold-water inlet of the housing by the pressure of hot water. CONSTITUTION:When a hot-water booster pump 7 is operated, a swing valve 13 is leaned on a cold-water inlet 11 by the pressure of hot-water to seal the cold-water inlet 11. When the hot-water booster pump 7 is stopped, the water level of hot-water in a housing 9 falls down by gravity along a pipe 20 and becomes equal to the water level in a hot water tank 1 because the swing valve 13 seals only the cold-water inlet 11. When a cold-water booster pump 8 is operated, the cold water in a cold-water tank 4 reaches the cold-water inlet 11 and pushes the swing valve 13 against a hot-water inlet 10 so that the swing valve 13 seals the hot-water inlet 10 and the cold-water is discharged through a spout pipe 12. When the cold-water booster pump 8 is stopped, the water level in the housing 9 falls down along a pipe 21 and becomes equal to the water level in the cold-water tank 4.

Filed: 1990-07-06
Abstract: PURPOSE:To prevent deflection of a board made of thermoplastic synthetic resin by retaining the board from above while the board is modified from a rubber state to a glass state, and horizontally holding the board. CONSTITUTION:A board 4 is gradually heated while being conveyed in a heating chamber 1 by a conveyor 6. The glass transition point T1 of the board 4 is about 150 deg.C, and the board 4 is modified from a glass state to a rubber state at the point T1. Then, the board 4 is heated to 183 deg.C or higher, and a cream solder 19 is melted. Thereafter, the temperature of the board 4 is gradually lowered to become a glass transition point T2 or lower. Thus, the board 4 is modified from a rubber state to a glass state. Thus, the board 4 is easily thermally deformed to be deflected while the board 4 is cooled to be modified from the rubber state to the glass state, but the deflection of the board 4 is prevented by retaining the board 4 by a retainer 16.

SOLUTION: A column-base fitting 11 is formed of a casting-forging product, in which a projecting section 11a is formed onto a plate-shaped bottom plate. A backing strip 20 is fixed at the specified place of the flat upper end face of the projecting section 11a, and a welding section 22 is formed through a beveling 12a shaped at the lower end of a steel-framed column 12. The wall thickness T of the projecting section 11a is made to correspond to maximum size in the wall thickness (t) of the column 12, and the fitting 11 is shared to various columns 12. An anchor bolt mounting the column 12 on a foundation is formed of the deformed bar steel of a screw-knotted reinforcement, etc., and formed in a U shape as required while a bottom is crossed in a plan view when the anchor bolt is buried into the foundation.  The large adhesion of a deformed section and the resistance force of concrete in the bent section of a bottom section resist tensile force. Accordingly, joining works and part-control can be facilitated, and fixing forced onto the foundation can be increased.
