Title: Dispersion type electroluminescent element
Inventor: MATSUSHITA YUMI
IPC: H05B33/12
Filed: 1988-04-13
Abstract: PURPOSE:To make it possible to drive by a low voltage and improve brightness by forming a light emitting layer and an insulation layer between a pair of electrodes at least either of which is a transparent electrode, and applying mixed liquid of hydrolysis liquid of metal alkoxyide and organic material of a high induction rate to it and drying it. CONSTITUTION:A transparent electrode 12 is formed on a glass substrate 11, and a light emitting layer 13 is formed on it including fluorescent matter such as ZnS:Cu scattered in cyanoethyl cellulose. An insulation layer 14 is formed by applying mixed liquid of hydrolysis liquid of metal alkoxide and organic material of a high induction rate on it and drying it, where the metal alkoxide liquid is of titanic acid barium formed of ultra-fine grains and having crystallization. Organic metal paste is applied on it to form a back electrode 15, and a protective film 16 of epoxy resin or the like is formed on it finally. The specific induction rate of the insulation layer is thus increased, and a fine and thin insulation layer is realized, while a voltage drop at the insulation layer is reduced, thereby a low voltage drive and a high brightness can be achieved.

Title: High speed transmission control circuit
Inventor: OGURA TOSHIHIKO
IPC: G06F13/00
Filed: 1989-04-14
Abstract: PURPOSE:To attain high speed data transmission by giving independent buses to the circuits of a control system and a data processing system in a transmission control circuit. CONSTITUTION:Transmission data is directly transferred to a host computer 10 via transmission FIFO 4, a transmission circuit for transmission 5 and a two port memory for transmission 2, and reception data via reception FIFO 6, transmission circuit for reception 7 and a two port memory for reception 3. Both data pass through a system bus S. Control data between the host computer 10 and the transmission control processor 1 is transferred by using a two port memory 11 and without passing through the system bus S. Control data between the transmission control processor 1 and a control circuit 8 is transferred through the local bus L of the transmission control processor 1. Thus, the access of the control system and the data processing system comes independent. Consequently, the collision of the access is cancelled and high speed data transmission can be realized.

Abstract: PURPOSE:To perform press formation using the hoop material of a resonator without trouble, to make the assembling process efficient, and to reduce the cost by integrally forming an edge part which radially spreads out in a plane shape at a large-diameter side outer periphery positioned above the resonator. CONSTITUTION:The hoop material 20 of this resonator is punched in a plane shape and then a main body part 22 is pressed in a funnel shape. In this case, the part outside the outer periphery of the main body part 22 is pressed in the funnel shape and the outer peripheral part still connects with a continuous part 21a in the plane shape to become the plane edge part 2E. Therefore, stress at the time of the formation is equally dispersed to the whole periphery of the main body part 22 and not concentrated on the connection part 21a connecting with a frame part 21, so neither the breaking of the connection part 21a nor the unnecessary deformation of the resonator 2 at the time of the formation is caused. A hoop material is used even for the metallic plate 1b of a unimorph vibrator 1 corresponding to the hoop material 20, and piezoelectric elements 1a are stuck on the metallic parts of the hoop materials to obtain a hoop-shaped unimorph vibrator.
