Filed: 1990-08-03
Abstract: PURPOSE:To improve motor efficiency by arranging an electric-mechanical energy conversion element such as a piezoelectric element plate, etc., in the node position of the vibration for driving or in the vicinity of the node position. CONSTITUTION:For a vibrator A, piezoelectric element plates 3 and 4 are caught and fixed between metallic elastic bodies 1 and 2. The electric-mechanical energy conversion elements such as the piezoelectric elements 3, and 4, etc., are polarized reversely with the nonelectrode parts in diameter parts as boundaries, and when electric fields are applied in the same direction in thickness direction to both polarizing regions, those are deformed as shown by the dotted line in the figure. Moreover, the electric-mechanical energy conversion elements 3 and 4 are arranged in the node position of the vibration mode for driving or in the vicinity of the node position. Accordingly, the attenuation constant is great, so those can be arranged in the part where the vibration excited by the vibrator A is small. Hereby, the internal abrasion loss of the vibrator A can be decreased.

IPC: B21C47/12
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To wind a wound material including a cooper wire on a drum in array. SOLUTION: In an array winding method, groove switching is performed by winding a wound material 1 on a drum 2 for every winding at an angle in fixed lengths to the direction of increasing the number of windings to increase the number of windings one by one. In step switching to switch the angled winding to the opposite direction, the position of the angled winding is shifted 1/8 to 3/8 of the fixed length from a one-precedent step. In order to keep accurate position, outer force is granted to the wound material 1 in the inward direction of the drum 2. The wound material can be automatically wound on the drum 2 in array and manual work to conventially correct disorder winding by a worker staying nearthere can be eliminated. In this way, labor can be saved as well as dangerous work can be avoided.
