Abstract: The present invention is intended to provide a carrying support that grasps work tubes different in length and type such that the lower ends are at the same height, is easy for the worker to carry by hand and realize automatic carrying, and is further capable of fixing the tube end portions to be processed in many cases at a constant height, thereby to assure the degree of freedom of designing manufacturing devices when the carrying support is also used as a jig for the devices. The carrying support is provided with a first grasping part (11) and a second grasping part (12) that grasp both end sides of work tubes (W) bent in middle parts at an upper position and extending downward.

Abstract: A method for manufacturing an elastic tubular body, comprises a first step of inserting a rod-like conductive member 2 into an elastic tubular body 1; a second step of giving a first electrical potential to the rod-like conductive member 2; and a third step of applying a coating material 31 charged to a second electrical potential to the elastic tubular body 1; wherein the rod-like conductive member 2 has a deformed cross-sectional shape in a direction vertical to an axial direction.

Abstract: A piezoelectric/electrostrictive film element includes a substrate, a lower electrode, a piezoelectric/electrostrictive film, and an upper electrode. The substrate has a thin-walled diaphragm portion, and a thick portion formed around the thin-walled diaphragm portion. The lower electrode is formed on the substrate in such a manner as to extend over the thin-walled diaphragm portion and the thick portion. The piezoelectric/electrostrictive film is formed on the lower electrode. The upper electrode is provided on the piezoelectric/electrostrictive film in such a manner as to face the thin-walled diaphragm portion. The upper electrode includes an upper-electrode body portion and a connection portion. The upper-electrode body portion has a planar shape generally similar to the planar shape of the thin-walled diaphragm portion.

Abstract: A method for grinding a number of objects includes a series of steps from arranging the objects to be ground on a grinding jig (a master plate) through removing the ground objects from the grinding jig after completion of the grinding process, smoothly and precisely without damaging a number of the objects to be ground and without altering the arrangement pattern of the objects to be ground from the start through the end of the series of steps.

Abstract: A piezoelectric/electrostrictive film element 10 includes a substrate 11, a lower electrode 12, a piezoelectric/electrostrictive film 15, and an upper electrode 16. The substrate 11 has a thin-walled diaphragm portion 11a, and a thick portion 11b formed around the thin-walled diaphragm portion 11a. The lower electrode 12 is formed on the substrate 11 in such a manner as to extend over the thin-walled diaphragm portion 11a and the thick portion 11b. The piezoelectric/electrostrictive film 15 is formed on the lower electrode 12. The upper electrode 16 is provided on the piezoelectric/electrostrictive film 15 in such a manner as to face the thin-walled diaphragm portion 11a. The upper electrode 16 includes an upper-electrode body portion 16a and a connection portion 16b. The upper-electrode body portion 16a has a planar shape generally similar to the planar shape of the thin-walled diaphragm portion 11a.
