Title: Coated electrode
Inventor: MIKI MASAO
IPC: B23K9/14
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To raise a current density, to improve welding efficiency, to reduce spatters and to improve a depositing speed by providing the flux layer covering the surface in the core wire provided recessed grooves in the longitudinal direction on the surface of a coated electrode at equal interval. SOLUTION: Since the core wire W2 is provided with recessed grooves 2 in the longitudinal direction on the surface, even though the diameter is the same as that of a conventional core wire, the cross section is smaller by the area equivalent to the cross section of recessed grooves 2 than that of the conventional core wire. Therefore, when the diameter of the core wire W2 is equal to that of the conventional core wire, the current density is more raised than the conventional one with the same large amount of current as the conventional one. By this way, the depositing speed is raised and welding efficiency is improved by using the core wire W2 . Also, when the amount of flowing current is the same as that of the conventional core wire, the core wire W2 having the larger diameter than the conventional one is allowed to use.  Further, since the core wire W2 is provided with the rugged part by recessed grooves 2 on the surface, the expansion of the arc is enlarged, moreover the arc is softened and spatters are reduced in the case of welding.

Title: Optical fiber type radiation leak detector
Inventor: KOBAYASHI YOSHINOBU
IPC: G01T1/00
Filed: 1985-01-18
Abstract: PURPOSE:To detect a leaked position over a wide range by providing an optical fiber coil so that a device from which radiation may leaks is covered widely. CONSTITUTION:A Ge doped quartz optical fiber coil 2 is wound around a nuclear reactor vessel many times. A direction coupler 3 is provided at one end of this coil 2 and the coupler 3 makes light from a light emitting element 5 incident on one terminal of the coil 2 and projects return light from the coil 2 sideward. The other end of the coil 2 is cut, for example, slantingly not to cause end surface reflection. The element 5 is made of, for example, a laser diode. If gamma rays leaks from the vessel 1, the structure of the core in the optical fiber is affected by the gamma rays at the leak point to increase a transmission loss, so that back scattered light varies. This back scattered light returns with some time delay behind incident light pulses, so this time delay is measured by a photodetector 7. Thus, the leaked position is known.
