Title: Tig welding method for galvanized steel sheets
Inventor: KAMO KEIZO
IPC: B23K9/23
Filed: 1988-07-13
Abstract: PURPOSE:To remarkably suppress consumption of an electrode by generating an arc at a place other than galvanized steel sheets and transferring that arc to weld the galvanized steel sheets. CONSTITUTION:A high-frequency current is carried between the electrode 6 of a welding torch 5 and a block 8 for generating the arc to generate the low- current arc. A welding current in this case is set low as compared with that of the galvanized steel sheets 1. When the low-current arc is generated, the welding torch 5 moves and attains a welding starting end W1 and then, stops. Here, it is changed over to the prescribed welding current and the welding torch 5 moves while welding the galvanized steel sheets 1. When the arc is generated repeatedly on the galvanized steel sheets, the consumption of the electrode becomes remarkable and when the arc is generated continuously, the consumption of the electrode is slight. Since the arc to influence the extent of consumption of the electrode 6 is generated between the electrode 6 and the block 8 for generating the arc, the consumption of the electrode 6 can be suppressed.

Title: Conveyor belt
Inventor: SASHIDE KAZUO
IPC: B65G15/34
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To facilitate maintenance and curtail the number of persons and the cost for maintenance by burying a reinforcing layer made of synthetic fiber textiles specifying cut-off elongation in the longitudinal direction and elongation at specified cutting load between the upper face cover and the lower face cover. SOLUTION: In this conveyor belt, a reinforcing layer 1 is buried between the upper face cover 2 and the lower face cover 3. In synthetic fiber textiles constituting the reinforcing layer 1, the cut-off elongation in the longitudinal direction is over 25%, and elongation in the longitudinal direction of the belt when a load equivalent to 10% of the cut-off load is applied in the longitudinal direction of the belt, namely elongation at 10% cut-off load is under 1.5%. By enlarging the cut-off elongation in the longitudinal direction of the belt of synthetic fiber textiles such as over 25%, in this way, the belt is apt to be deformed by a large load, and hence stress concentration can be softened. Further, by setting the elongation in the longitudinal direction at 10% cut-off load under 1.5%, the elongation in the longitudinal direction of the belt is restrained to be small.

Title: Optical control element
Inventor: MIYAZAWA HIROSHI
IPC: G02F1/313
Filed: 1990-07-02
Abstract: PURPOSE:To couple the optical control element with an optical fiber, etc., with low loss and to enable low-voltage operation by making the width of an input/output optical waveguide on the side of its light input/output end narrower than the width of the pattern on the optical control part. CONSTITUTION:Incident light 15 to the light input end, e.g. 11 is passed through the input optical waveguide 7 and guided to the optical waveguide 2 of the optical control part 6. Optical waveguides 2 and 3 are arranged closely to each other to constitute a directional coupler and the energy of the propagated light in the optical waveguide 2 moves to the optical waveguide 3 gradually. Here, the length of the optical waveguides 2 and 3 is selected equally to complete coupling length. Therefore, when an applied voltage is 0, the incident light 15 passes through the optical waveguide 3 and an output optical waveguide 10 and is projected from the light output end 14 as projection light 16. When a voltage is applied to electrodes 4 and 5, on the other hand, the phase constants of propagated light beams in the optical waveguides 2 and 3 do not match each other and the coupling between the optical waveguides 2 and 3 become 0 at a certain voltage value, so that the incident light 15 is projected as projection light 17 from a light output terminal 13 through the optical waveguides 2 and output optical waveguide 9.

For example, a sample to be examined is received in the wells of a microplate to form the diluted system thereof and the sensitized particles are added to each of the wells to be mixed with the sample to be examined and the agglutination image thereof is observed after the sample to be examined is allowed to stand. By this method, albumin and transferrin in the urine sample can be accurately and simply detected with high sensitivity and, as a result, a large amount of the sample can be measured within a short time.
