An organic EL panel forms at least one organic EL element on a substrate. The organic EL element has a laminating structure in which an organic layer including a light-emitting layer is arranged between an anode and a cathode. A light-emitting region in which the organic EL element is formed and a wiring region in which a wiring electrode is formed are formed on the substrate, the wiring electrode is drawn out from the light-emitting region and is electrically connected to the anode or the cathode of the organic EL element, and the wiring electrode has a planarly R shaped portion having a rounded corner at the end part on the side of the organic EL element.

Organic EL panel and method of manufacturing the same

For organic EL panels with a hollow-sealed structure to meet the demand of flat or large displays, the inconvenience of contact of drying anent etc touching the organic EL elements in the sealed space is avoided. An organic EL panel includes a panel substrate, a light-emitting part with a plurality of organic EL elements having an anode, an organic layer and a cathode laminated on the panel substrate, and a sealing substrate configured to be bonded onto the panel substrate through an adhesive layer to seal the light-emitting part. The sealing substrate includes a supporting projection projecting toward the panel substrate. A supporting margin facing to the bottom face of the supporting projection is provided where the organic EL elements is not formed within a region of the light-emitting part on the panel substrate.

A method for manufacturing an image display element including: a front panel; a back panel facing the front panel; plural pixels arranged in a matrix between the panels, and to be selected to be in a display or non-display state; and plural electrodes for controlling the pixels, the panels being bonded with the pixels and the electrodes interposed therebetween, and the electrodes being connected to a driving control circuit via metal wires, includes a first step of performing dicing from the back side of the opposing surface from the front panel, and forming a groove part such that electrode terminals connected to the electrodes are exposed between adjacent plural pixel lines, with the back panel bonded thereto, and a second step of forming the metal wires so as to be connected to the electrode terminals exposed at the groove part.

Method for manufacturing image display element

An image display element includes: a front panel; a back panel opposite thereto; a plurality of pixels arranged between both the panels; and plural electrodes for controlling the pixels. The panels are bonded with the pixels and the electrodes interposed therebetween, and the electrodes are connected to a driving circuit via metal film wires. The back panel is divided so as to expose electrode terminals, and a groove part V-shaped in cross section is formed at the divided portion. The metal film wires are formed on the top surface of the back panel, and the electrode terminals and the metal film wires are connected by a conductive paste coated along the tilt surfaces forming the groove part. Partitions are disposed between the adjacent electrode terminals at the bottom of the groove part.

An image display element includes: a front panel; a back panel opposite to the front panel; a plurality of pixels arranged in a matrix between both the panels, and to be selected to be in a display or non-display state; and plural electrodes for controlling the pixels. Both the panels are bonded together with the pixels and the electrodes interposed therebetween, and the electrodes are connected to a driving control circuit via metal wires. The back panel is divided such that electrode terminals connected to the electrodes are exposed between adjacent plural pixel lines, and a groove part having a shape wider at the top on the back side of the opposing surface from the front panel than at the bottom is formed at the divided portion. The metal wires are connected to the exposed electrode terminals of the groove part.

The rotary magnetic head apparatus of this invention exhibits an optimum transfer characteristic similar to that in the conventional apparatuses even when the number of coil turns for the magnetic head is reduced to 10 or less. This is achieved by setting the number of secondary winding turns for the rotary transformer to 16 or less and by setting the number of primary winding turns for the rotary transformer in such a way that a product of a step-up ratio--defined as the number of secondary winding turns divided by the number of primary winding turns--and the number of coil turns will be around 50. This reduction in the number of turns of coil on the magnetic head, from 20 or 25 with the conventional apparatus to less than 10, results in a substantial reduction in the cost of magnetic head and therefore the rotary magnetic head apparatus.

Rotary magnetic head apparatus

An acoustic diaphragm formed of beryllium or an alloy composed mainly of beryllium. Said diaphragm has a crystal structure having its plane (1120) preferentially orientated in parallel with the surface of the diaphragm.

Acoustic diaphragm

A honeycomb core diaphragm is described, which contains a honeycomb core made from a thin plate of beryllium or beryllium alloy which is produced by a super-rapid cooling method. Since the thin plate of beryllium or its alloy has a high modulus of elasticity and low density and, furthermore, is easily moldable, it can be easily molded to produce a honeycomb core having a high modulus of elasticity and low density.

Honeycomb core diaphragm

A diaphragm for use in a loud speaker is constructed of a substrate formed into a diaphragm configuration from a thin plate or a sheet composed of an organic or an inorganic substance, and a coating layer made of boron, or, an alloy of which a major component is boron or a chemical compound of boron, being provided onto at least the surface of said substrate.
