Title: Surface acoustic wave device
Inventor: MATSUDA TOSHIYA
IPC: H03H9/145
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To increase suppression effect on discharge by forming a surface acoustic wave SAW resonator, a wiring pattern, and a conductive film for a lead-out pad electrode on a piezoelectric substrate to larger than specific area, and providing a protection film on the resonator. SOLUTION: The area of inter-digital IDT electrodes 2a and 2b, a reflector 2c, a pad electrode 4, and a conductive film for a wiring pattern 5 on one main surface of a piezoelectric substrate 1 is set to >=225% of the area of the main area of the substrate 1. Consequently, the area of the conductive film which is fast in the speed of acquisition of electric charges suspended in air becomes large and electric charges on the conductive film and substrate 1 are neutralized fast. Further, the protection film is lower in the generation rate of discharge when it is provided only on the SAW resonator 2 than when the protection film is provided over the entire the main surface of the substrate 1 or not provided at all.  The protection film 6 is easy to short between electrode fingers when the resistance along the film is <=10<9> Ω and decreases in the electric charge neutralizing operation and a semiconductive resistance of approximately 10<9> to 10<13> Ω is used.

Title: Resistance welding machine
Inventor: TAKAHASHI MASAYUKI
IPC: B23K11/14
Filed: 1986-05-12
Abstract: PURPOSE:To reduce the inert gas amount used for a resistance welding by movably supporting a chamber to one part of the welding electrodes and providing the feeding pipe selectively feeding an inert gas to the chamber on the welding electrode of the other part. CONSTITUTION:A cap 5 is fitted by a magnet 3 to the electrode chip 2b of the upper part electrode 2 and a base 9 is fitted to the lower part electrode 6. An inert gas is jetted from exhaust nozzles 8a, 8b via a feeding pipe 8 with a valve 10 being opened simultaneously with the descent of the upper part electrode 2. When a chamber 1 reaches near to the lower part electrode 6, the descent of the upper part electrode 2 is once stopped and the inside of the chamber 1 is replaced by the inert gas. The upper electrode 2 is then descended again, the cap 5 and base 9 are pressed with the prescribed force, the electrodes 2, 6 are electrified and the projection welding is performed. With completion of the welding, the valve 10 is closed, the cap 5 is pushed to the lower part by descending a rod 4, the upper electrode 2 is ascended and the welded cap 5 and base 9 are taken off. In this way, the use amount of the inert gas can remarkably be reduced.

Title: Method for analyzing continuous flow
Inventor: TAKAHATA FUJIYA
IPC: G01N21/75
Filed: 1985-05-22
Abstract: PURPOSE:To improve the reproducibility of measurement in a method for analyzing continuous flow to measure a light absorption characteristic by adding a refractive index adjusting agent to a carrier liquid so as to attain substantially the same refractive index as the refractive index of the reaction product. CONSTITUTION:Distilled water having 1.3330 refractive nidex is usually used as the carrier liquid. Said water has a difference from 1.3435 refractive index of, for example, a GOT measuring test liquid of a tris buffer soln. and such difference is the cause for optical disturbance. A salt, org. compd., surface active agent, etc. are thereupon added to the carrier liquid to increase the refractive index and to adjust the refractive index to the extent at which the upper three digits coincide. The refractive index is made approximately equal to the refractive index of the GOT measuring test liquid if 1.16M NaCl is added to the carrier liquid. As a result, the influence of the optical disturbance after the closure of pinch valves at both ends of a flow cell is eliminated. The range of a linear change in the stage of measuring the change in the lapse of time is thus expanded and the increase of the number of the data to be taken is made possible.

Title: Device for installing reference electrode
Inventor: ISERI HAJIME
IPC: G01N17/02
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To accurately measure a potential continuously for a long time by dipping a reference electrode in a container where the extreme tip is made of an ion permeable solid material and installing the tip part of a container while it projects from a water passage part. SOLUTION: One edge of a container body part 1 has an electrode fixed part 2, the other edge has a tip part 3 and the extreme tip of the tip part 3 is an ion permeable part 4 consisting of an ion permeable solid material. A support body 5 has a water passage part 6 and both edges of the water passage part 6 are pipe connection ports 7 that can be connected to a pipe. Then, a reference electrode 10 is dipped into an electrolyte solution 9 being filled into the container body 1 and is fixed by an electrode-fixing part 2 and the tip part 3 is dipped into the water passage part 6 while it projects from the part 6. In this manner, the ion permeable part 4 is located near the center of the section of the water passage part 6, thus preventing air stagnation from occurring easily and enabling a fluid to flow smoothly in the water passage part 6.  Also, the concentration of an electrolyte constituent can be made constant by replenishing and exchanging the electrolyte solution 9 periodically.
