IPC: H01L41/316
Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To simplify electrode structure for external wiring by providing an electrode film and a non-terminal part at the electrode formation layer between the laminated piezoelectric films of a multilayer piezoelectric actuator. SOLUTION: A multilayer piezoelectric actuator is provided with only the terminal part of the electrode film of odd-numbered layers on one side surface, and only the terminal of the electrode film of even-numbered layers on the other side surface. Electrodes and non-terminal parts 6, 16, 26, and 36 are provided between piezoelectric films 8. The electrode does not conduct electricity even if the non-terminal parts 6, 16, 26, and 36 are in contact with the electrode for external wiring. Therefore, even if the electrode for external wiring is formed at the non-terminal parts 6, 16, 26, and 36 of the electrode formation layer, electrode films 4, 14, 24, and 34 on the layer do not conduct electricity.  By forming the non-terminal parts 6, 16, 26, and 36, the degree of freedom for designing the electrode and wiring for external wiring can be improved, and simplified wiring structure can be obtained efficiently.

Title: Vacuum and pressure forming method
Inventor: MIYAGAWA YOICHI
IPC: B29C51/30
Filed: 1990-06-15
Abstract: PURPOSE:To develop no deformation at respective terminal parts in continuous forming even when there is a difference in level between both the terminals of each product, save waste of resin material and make it possible to reinforce the terminal of the product by a method wherein the gap of a part, which is to be cut off after forming, is set to be smaller than the thickness of sheet material so as to perform the pre- stretching, by which the thin-walled vertical face is formed by clamping molds. CONSTITUTION:When mold clamping is performed by lowering an upper mold 10, soft sheet material 9 in the gap between the projected part 24 of a lower mold 11 and the forming face 25 of an aluminum plate 22 is pinched so as to be squeezed and pre-stretched in order to form a thin-walled vertical face 30. And, most resin material scraped off by squeezing is fed to the bottom part of a channel, which is formed by the forming face for the L-shaped part 6 of the upper mold 10 and the forming face 25 of the aluminum plate 22. As a result, at the forming and solidification of the sheet material, the wall thickness, which is necessary from the viewpoint of strength, is ensured at the L-shaped part 6. Further, since the molds have a simple structure, to which only the aluminum plate 22 is attached with bolts, neither large- sized mold nor large-scale equipment is required.

Abstract: PURPOSE:To record correctly an image to a prescribed position on a recording paper irrespective of variable power of the image, by executing the recording corresponding to setting of a magnification, in case when the image which has been read by a read means is brought to variable power and the image is recorded. CONSTITUTION:When an operator indicates a rolling reduction corner of a desired image area by operating cursors 18, 23, and also inputs a variable power alphaby a magnification setting device, voltages V18, V23 corresponding to the cursor position are read by potentiometers 21, 26. Subsequently, a scanning speed v/alpha of a carriage is calculated by multiplying a scanning speed (v) of the carriage when a variable power is '1', by an inverse number 1/alpha of the variable power. In this way, by changing the scanning speed in accordance with the variable power, a scanning line density of a one-dimensional line sensor is varied, and the variable power of the image in the sub-scanning direction is executed. Next, a carrying timing of a recording paper is calculated, by which a recording start timing corresponding to a designated area is increased or decreased, and the image is always recorded at a prescribed position of the recording paper.
