Title: Profile polisher
Inventor: MATSUSHITA KOICHI
IPC: B24B13/02
Filed: 1987-03-19
Abstract: PURPOSE:To make surface roughness of a workpiece into the smallest possible extent as well as to form the work surface into flawless mirror finishing, by constituting a polisher to polish a work in a way of rocking it while rotating a polishing tool and the work in making contact with each other. CONSTITUTION:A tool 32 and a workpiece 31 are rotated, and they are relatively rocked. Therefore, the tool 32 (an abradant such as a pellet) comes into uniformly contact with a work surface of the workpiece 31 without exception. And, the tool 32 is supported on a tool holder 2B via elastic bodies 33 and 34. With this constitution, even if the workpiece 31 is of aspherical form, the tool 32 can be made to smoothly follow the curved form. In consequence, surface roughness of the workpiece 31 is made into the smallest possible extent and, what is more, flawless mirror finishing is securable.

Title: Braking device for vehicle
Inventor: NAGAHORI TAKASHI
IPC: B60T1/06
Filed: 1979-05-25
Abstract: PURPOSE: To improve braking efficiency for vehicles, by pressing a braking member on to a brake drum with the member being rotated in the positive rotational direction of the brake drum.  
     CONSTITUTION: A brake lining 5 is mounted on the circumferential side of an annular pad 4 with a distance from it and at the same time a braking face 21 of the brake drum 2 is tilted with a suitable tilting angle. In this construction, when a brake operating wire is pulled while the brake drum is rotating positively in the direction indicated by the arrow, a push rod 10 rotates to shift the annular pad 4 to the side of the brake drum, and the brake lining 5 is forced to be pressed on to the braking face 21 and effects braking. Because, at this time, the annular pad 4 moves along a helical groove 8 of a helical drum 7, the brake lining 5 contacts the braking face 21 while it is rotating in the rotational direction of the brake drum 2 and develops a large frictional force between them to give a large braking force.
