Title: Reducing method for electrolytic corrosion at contact of dissimilar metal
Inventor: YAKUSHIJI YOSHIO
IPC: C23F13/00
Filed: 1978-06-26
Abstract: PURPOSE: To reduce the electrolytic corrosion, in case of the low potential metal and the high potential metal making contact, by metalizing the intermediate potential metal on the contact part.  
     CONSTITUTION: In case of the low potential metal 4 and the high potential metal 5 making contact, the intermediate potential metal is metalized 6 on the side of metal 4. The metalization 6 can be applied to either one or both of two metals 4, 5. Hereby, the potential difference between two metals 4, 5, can be reduced, which then makes possible the electrolytic corrosion of the metal 4 to be reduced. This method is suitable for preventing the electrolytic corrosion at the end part of the heat exchanger tubes of the seawater demineralizing plant, or the condenser, etc., included in the boiler, or the nuclear power plant which is utilizing the seawater as the cooling water.

Abstract: PURPOSE:To absorb the rotational difference between inner and outer wheels in tuning without requiring any complex control, by halving the rotor of a motor, and by holding respectively the halved rotors in an individually rotatable way, and further, by coupling the wheels to the respective ends of the halved rotors. CONSTITUTION:One rotor is halved into two rotors 120, 130, in the middle of an armature. The rotors 120, 130 are inserted compressively into shafts (123), 133 respectively, and on their one-end sides, they are coupled to each other in an individually rotatable way by a plane bearing 150. On their other end sides, the respective shafts (123), 133 are held on end frames (141), 142 via bearings 125, 135 in a rotatable way respectively. Based on the driving signal given from an accel, the rotors 120, 130 are rotated in two equal directions at two equal rotating speeds with two equal torques. The torques are transmitted to driving wheels via decelerators 2 and equal-speed ball joints respectively. Since the left and right wheels can be rotated independently by virtue of the halved rotors 120, 130, no differential gear is required, and the rotational difference between the inner and outer wheels when turning can be absorbed.
