IPC: B41J21/00
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To enable simple execution of double-side printing by a printer for single-side printing. SOLUTION: Print data generated from an application are stored in a spooler file 303 on a page-by-page basis. When a spool file manager 304 judges the data to be printable, on the occasion of executing double-side printing, it gives a despooler 305 an instruction to output a request for printing. On the occasion, the sequence of the output is determined on the basis of the direction of paper feeding and the direction of paper delivery obtained from a printer 1500. In the case of face-up feeding and face-up delivery and in the case of the data of six pages in total, for instance, the output is made first in the sequence of 6, 4 and 2 and then in the sequence of 5, 3 and 1 after paper is reset. In this way, the double-side printing can be executed simply by a single-side printer as well, according to the type of the printer.

Filed: 1987-07-16
Abstract: PURPOSE:To obtain a lighting device repeatedly usable via the removal and renwal of an electric discharge lamp by connecting a positive characteristic thermistor in series to a preheating circuit between terminals at the non-powered side of the filament electrodes of the electric discharge lamp. CONSTITUTION:A positive characteristic thermistor 16 is connected in series to a preheating circuit between terminals at the non-powered side of the filament electrodes 6a and 6b of an electric discharge lamp 5 connected via the current- limiting choke 4 of a high-frequency inverter. When the electric discharge lamp 5 becomes a live end and an emitter-less state appears thereby giving a pre- heating start condition, therefore, a large amount of current runs to the thermistor 16 and a Curie temperature level is thereby exceeded. Then, the resistance value of the thermistor 16 suddenly increases and load current drops substantially. As a result, the circuit is protected and the destruction of circuit elements like a transistor is prevented, thereby enabling the re-use of a lighting device for an electric discharge lamp via the renewal of the lamp.
