Title: Manufacture of thin film electroluminescence element
Inventor: SANO YOSHIO
IPC: H05B33/10
Filed: 1988-10-25
Abstract: PURPOSE:To secure a high grade display quality for a long period without errors of light emission at an upper part and a lower part of an electroluminescence panel by a long period use of the electroluminescence panel by applying a heat process in a predetermined temperature range after formation of an insulation layer. CONSTITUTION:After a film of an insulation layer 5 is formed, a heat process is applied at 300-650 deg.C for stabilizing the properties of the insulation layer 5. As a result, uncombined atoms, etc., left chemically unstable are changed to be chemically stable by thermal energy. Because of staibilization of the film quality, chemical reaction at the boundary of a light emitting layer 6 laminated on the insulation layer 5 and the insulation layer 5 and mutual diffusion of component atoms of the layers 5, 6 are eliminated. If asymmetrical voltages with relation to the phase are applied for a long period, therefore, a large decrease of a starting voltage of light emission is eliminated, thereby errors of light emission can be prevented.

IPC: H01L31/0264
Filed: 1988-10-26
Abstract: PURPOSE:To establish high speed operation by inserting a thin barrier layer having a resonant tunneling effect into part of a passage for an optical carrier. CONSTITUTION:An about 50-70Angstrom  thick barrier layer 21 is formed on an n-InP substrate 1 through a well layer 20, and an absorptive layer 2 is formed on the barrier layer 21. Electrodes 4 and 5 are provided on the substrate 1 and a p layer 3, respectively, and an optical fiber 6 for guiding light to be detected is fixed to the substrate 1 side through epoxy resin 7. Since in such a manner the barrier layer 21 having a resonant tunneling effect is inserted into a passage for an optical carrier as an energy barrier, electrons useful for a high speed are passed while holes not useful for high speed operation is prevented from being passed using selective transparency by the resonant tunneling effect. Thus, the detector can be operated at a high speed.

Abstract: PURPOSE:To prevent the occurrence of color disturbance by extending a fine adjustment controllable range when a detection point alternately follows up and jumps tracks and gradually supplying components lower than a prescribed level into an error signal to a rough adjusting means to perform rough adjustment with all components. CONSTITUTION:In response to the scanning command, a controller 40 stops rewriting a RAM 33 synchronously with the generation of a vertical synchronizing signal by a separating circuit 26 and forcibly drives a slider 9 by a motor driving means 7 and outputs a signal (a) to open a tracking servo 52 for 10ms, and a pickup 3 jumps.
