Title: Manufacture of heat exchanger made of aluminum
Inventor: YAGI MITSUYA
IPC: B23K1/00
Filed: 1980-05-30
Abstract: PURPOSE: To obtain a nicely soldered heat exchanger preventing pitting corrosion without corrosion of a heating furnace by beforehand applying zinc plating on an aluminum base metallic material which needs anticorrosive treatment and executing heat soldering without using flux.  
     CONSTITUTION: The surface of material such as tube and tank that specially requires anticorrosive treatment among Al or Al alloy members constituting a heat exchanger is applied to zinc plating. By this way, Al oxide film on the surface of the members is removed. The heat exchanger is temporarily assembled through layering solder on the surface of parts contacting with members which do not require anticorrosive treatment. This is soldered by heating in a furnace of inactive atmosphere. At this time an oxide film is formed on the zinc plated surface. However, as this is not so stable as Al oxide, soldering is executed satisfactorily without using flux. Zinc diffuses into the Al base material during heating, and the formed diffusion layer acts as a sacrifice electrode to prevent pitting corrosion of the base material.

Title: Grinding method in grinder
Inventor: YAMAMOTO NOZOMI
IPC: B24B49/00
Filed: 1983-04-26
Abstract: PURPOSE:To prevent a grindstone to be worn one-sided and to vibrate, and to highly accurately grind even a thick workpiece by performing at least one displacement of notching or traverse feed only in a state where a grindstone wheel is separated from a workpiece. CONSTITUTION:A dog 13 is provided on one part of a holding body 5 travelling in a body with a grindstone wheel 1, and upper and lower part sensors 15, 17 capable of changing and setting their positions adjusted to the height of a workpiece 9 are provided on proper positions of a machine frame, etc., of a grinder 3 corresponding to the dog 13. Accordingly, when the grindstone wheel 1 separates away the upper or lower surface of the workpiece 9, the upper part sensor 15 or the lower part sensor 17 issues a signal, but during grinding it does not issue a signal. Namely, when a sensor ON signal is transmitted to a work control part, a signal for releasing a shaft interlocked is transmitted to a numerical value control part, a command pulse ON to a servo system is issued to actuate a servo motor to cause a lead screw shaft to be driven, thus allowing at least one displacement in the X and Y axis direction to be performed. In this way, there is no displacement during the grinding, so that it is possible to highly accurately grind any workpiece.
