Title: Rotary electrode roller and its manufacture
Inventor: NISHIYAMA SUMIO
IPC: B23K11/04
Filed: 1979-11-28
Abstract: PURPOSE: To prevent oxidation of fusible alloy and to improve conductive efficiency, by filling the closed narrow space between the fixed part and rotating part of electrode roller with a fusible alloy and an inert gas.  
     CONSTITUTION: Rotating part 20 is fitted to fixed part 10 of the electrode roller so that the rotating part will not rotate, and compressed nitrogen gas is jetted into narrow space 40 by inserting injection needle into injection port 33 and the air in the narrow space 40 is replaced with the compressed nitrogen. Then injection needle 51 of closed container 50 to be used for keeping fusible alloys is inserted into the injection port 33, and an inert gas, such as compressed nitrogen gas, etc., is blown into container 50 through its blowing port 52, and thus liquid fusible alloy contained in the container 50 is injected into the narrow space 40. At this time, a part of nitrogen gas contained in the space 40 is discharged through a discharge port 34. After the fusible alloy is injected, discharge port 34 and injection port 3 are closed and narrow space 40 is filled with the nitrogen gas and the fusible alloy. By this arrangement, the fusible alloy contained in the electrode roll will not be oxidized by contacting with the air and will maintain its efficiency as a conductive medium.

Title: Method for discriminating defect by ultrasonic flow detection
Inventor: YUASA YOSHIRO
IPC: G01N29/04
Filed: 1995-06-21
Abstract: PURPOSE: To judge the grade of importance of a detected defect by discriminating the front-end shape of the defect. CONSTITUTION: Ultrasonic waves radiated toward a defect 4 in a test pieces 3 which is an object to be inspected from a probe 2 are caught by the probe 2 after being reflected by the end section of the defect 4 and a flaw detector 1 recognizes the signals as end section echoes. By finding a threshold for discriminating sharp front ends and curved front ends (having large crack developing possibilities and small crack developing possibilities) from each other based on a pre-found relation between the front end shapes of defects and sound pressure levels of end section echoes (sensitivity of the flow detector 1), the front end shape of the defect 4 is discriminated by comparing the sound pressure level of the front end echoes from the test piece 3 with the threshold.  Therefore, the front end shape of the defect of an object to be inspected can be discriminated and the severeness of the defect can be judged.

Title: Fullerene synthesizing device
Inventor: TANIGAKI KATSUMI
IPC: C01B31/02
Filed: 1991-06-27
Abstract: PURPOSE:To provide the device for easily synthesize fullerene at a high yield. CONSTITUTION:An evaporating carbon rod 1 having a diameter within 1mm and a counter electrode carbon rod 2 having the diameter of >=2 times this diameter are brought into contact with each other. The circumference of the carbon rods 1, 2 is enclosed by a cylinder 20. Two holes facing each other are provided on the cylinder 20. The one of these holes is used as a helium introducing port 4 and the other as a suction port 5a for collecting the formed carbon powder. The suction port is differentially discharged and the carbon powder gathers at the collector 6. The carbon rods 1, 2 are heat under resistance to evaporate the carbon from the carbon rod 1. Since just two holes are bored at the cylinder 20, the smooth flow of the carbon vapor from the introducing port 4 side to the suction port 5a side is generated. More than 85% of the consumed carbon rod 1 is, therefore, collected as the carbon powder in the collector. More than 15% in the recovered carbon powder is the fullerence (C60, C70). Since the diameter of the evaporating carbon rod 1 is confined to <=1mm, there is no need for a large-capacity power source.
