Abstract:
A deformation suppressing structure is formed on a surface of a flexible plate-like member. The deformation suppressing structure includes recesses and ridges formed on the surface of the plate-like material. The recesses and ridges are shaped such that, when the plate-like member is deformed within the region of elastic deformation, ridges adjacent to each other are in contact with each other to suppress further deformation. By this, excessive deformation that may cause permanent deformation is prevented and resistance to stress is enhanced. The flexible substrate can be used for an image display device having flexibility.
Abstract:
Disclosed is an improved method of embedding capacitors in printed wiring boards (PWB) made from thick film dielectrics and electrodes, the method comprising the steps of : providing a metallic foil; forming a ceramic dielectric over the metallic foil; forming an electrode over most of said dielectric and at least a portion of said metallic foil; firing the capacitor structure under base metal firing conditions; and etching the metallic foil to form a second electrode. Further the method may comprise forming an insulating isolation layer over the metallic foil before forming the ceramic dielectric.
Abstract:
Polymer materials are useful as electrode array bodies for neural stimulation. They are particularly useful for retinal stimulation to create artificial vision, cochlear stimulation to create artificial hearing, and cortical stimulation, and many related purposes. The pressure applied against the retina, or other neural tissue, by an electrode array is critical. Too little pressure causes increased electrical resistance, along with electric field dispersion. Too much pressure may block blood flow. Common flexible circuit fabrication techniques generally require that a flexible circuit electrode array be made flat. Since neural tissue is almost never flat, a flat array will necessarily apply uneven pressure. Further, the edges of a flexible circuit polymer array may be sharp and cut the delicate neural tissue. By applying the right amount of heat to a completed array, a curve can be induced. With a thermoplastic polymer it may be further advantageous to repeatedly heat the flexible circuit in multiple molds, each with a decreasing radius. Further, it is advantageous to add material along the edges. It is further advantageous to provide a fold or twist in the flexible circuit array. Additional material may be added inside and outside the fold to promote a good seal with tissue.
Abstract:
An anti-deformation structure is formed on the surface of a flexible plate-shaped part. The anti-deformation structure includes protrusions and depressions formed on the surface of the plate-shaped part. The protrusions and depressions has a shape in which adjacent protrusions become in contact with each other in the state when the plate-shaped part is deformed within a range of elastic deformation, restricting further greater deformation, and thus, preventing excessive deformation leading to permanent deformation and raising the resistance to the stress. The flexible base material can be applied to flexible image-displaying devices.

Abstract:
A surface electrode is provided on a surface of a piezoelectric, element for changing the volume of each pressure chamber in an inkjet head. The surface electrode has a main electrode portion opposed to the pressure chamber and a connecting portion not opposed to the pressure chamber. A land is provided on one end of the connecting portion of the surface electrode. The land is electrically connected to the surface electrode. When the land is connected to a terminal of an FPC, a driving signal can be transmitted to the surface electrode. The land is therefore connected to the terminal using solder and a thermosetting resin covering the surface of the solder, or using only a thermosetting resin.
