IPC: B41J2/455
Filed: 1990-10-11
Abstract: PURPOSE:To prevent the breakage of each part of circuits even with the occurrence of the short circuit of EL elements by a method wherein an ON resistance to one block electrode of a block driver is so increased as not to inhibit a light emitting action of end face emitting-type EL elements. CONSTITUTION:Where an ON resistance to one block electrode 21 of a block driver 30 is Rbron, an allowable current value is Ibr, the total capacity of end face emitting-type EL elements 19 is CEL, a positive or negative drive pulse application time of a common driver 33 is T, an electric potential difference between drive pulses of the block driver 30 is E0, a voltage included in the electric potential difference E0 as a margin is E1, and a voltage of a drive pulse to be applied to the EL element 19 is + or -E, a relation of E/Ibr<Rbron<=- T/{CELXIn (E1/E0)} is held in a printer 28. Even if the short circuit of the EL element 19 occurs during the drive of a line head 20, the block driver 30 regulates the inflow of a high-tension drive pulses outputted from the common driver 33 by the large ON resistance thereof, thus preventing the breakage of a drive IC 29 and the like.

Title: Optical element and manufacture therefor
Inventor: OIIZUMI HIROAKI
IPC: G03F1/24
Filed: 1992-10-12
Abstract: PURPOSE:To fabricate an optical element such as a reflection type mask or the like which enables substrate recycling. CONSTITUTION:A thin film layer 119 is provided between a substrate 11 and a multi-layer film 22 in an optical element. Thus if a defect is found in the multi-layer film 22, the multi-layer film 22 and the thin film layer 19 are removed to re-use the expensive substrate 11. Since the thin film layer protects the substrate surface in removing the multi-layer film, the substrate can be recycled without losing super-smoothness of the substrate, thereby reducing a manufacturing cost in optical element fabrication.

Filed: 1987-10-28
Abstract: PURPOSE:To abate the damage of a sheet and its conveying failure at the time of its turning over by constituting at least a part of a U-shaped turnover route for sheet turnover use, with a rotor free of rotation. CONSTITUTION:A sheet S so far fed out of an upstream is turned over and conveyed to a downstream by way of a U-shaped turnover route 11.
