Title: Data storage system
Inventor: NONAKA NAOMICHI
IPC: G06F17/40
Filed: 1990-06-01
Abstract: PURPOSE:To prevent the loss of data during the processing by producing an interruption signal to a CPU and starting a data saving means when the inputted voltage drops less than a reference level. CONSTITUTION:The value of impacts applied to an equipment form outside is measured by accelerometer 10. When a comparator 20 detects that the measured value of impacts exceeds a fixed level, a data saving program 1000 is started to save the dta under processing into an extension memory 80 from a main memory 40. The memory 80 lacks a movable part and therefore is never damaged with some impacts. Furthermore the power is supplied to the memory 80 from an independent back-up power supply. Thus the data contents destroyed in their processing mode can be restored.

Title: Recording device
Inventor: SUGIYAMA HIROSHI
IPC: B41J13/10
Filed: 1984-07-11
Abstract: PURPOSE:To obtain a uniform recording picture having high quality by bringing a guide member guiding the travelling of a carriage for a recording head into pressure-contact with a record medium on recording. CONSTITUTION:Recording is conducted in such a manner that a recording head 4 is driven and ink drips D adhere onto a record medium 1. Sections extremely near by the positions of recording of the record medium 1 are pushed only because the height of the upper end of a flange 12a is slightly lower that that of the positions of recording where ink drips D fly at that time. Since the front surface of a guide rail 12 conducting pushing is formed in a plane and a platen 2 section facing the front surface of the guide rail 12 is also shaped in a plane, the area of a pushed section in the record medium 1 is made extremely larger than conventional devices, and continued. Accordingly, even when the record medium 1 is creased and curled, sections in the vicinity of the positions of recording of the record medium are fast stuck onto the platen 2 approximately completely, and a uniform plane is formed, thus keeping distances among the record medium 1 and the recording head 4 at the positions of recording constant, then acquiring an equal recording picture having high quality.

IPC: G03G21/00
Filed: 1994-06-01
Abstract: PURPOSE:To maintain the using amt. of a photosensitive drum with a small memory capacity and to judge the life of the photosensitive drum nearly exactly by integrating the using amt. of the photosensitive drum not as a number of revolutions but as a number of printing sheets. CONSTITUTION:A CPU 220 reads out a printing processing routine held in a ROM 251 and starts printing processing when an instruction for printing is made. Printing preprocessing is progressed by adding a 1 to the integrated value of the drum held in the drum life integrating region of an NVRAM 280 and printing is started by adding a 1 to the integrated value of the number of sheets held in the integrated value region of the number of printing sheets of the NVRAM 280. The CPU 20 makes judgment as to whether there is the next printing start or whether printing of the second sheet is to be executed or not. Next, the step is returned to the previous step if there is the instruction for the printing start. The 1 is then added further to the integrated value of the number of sheets held in the integrated value region of the number of printing sheets of the NVRAM 280. The printing of the second sheet is started and the integrated values of the number of sheet are added according to the number of printing sheets. The processing routing is ended upon completion of printing.
