Abstract: PROBLEM TO BE SOLVED: To prevent forgery of paper monies and illegal copies of a literary work by generating a hidden pattern with a set size and imbedding it into a print image, while reducing the size of the hidden pattern to the utmost. SOLUTION: A driver 5 of a host computer 1 is provided with a print data generating section 8 that generates print data fed to a printer 2, a hidden pattern generating section 9 that generates a hidden pattern to be imbedded into the print data, and an imbed discrimination section 10 that discriminates whether or not the hidden pattern generating section 9 generates a hidden pattern based on the result of analysis by a graphic device interface(GDI) module 6. Then the size of the hidden pattern is decided, so that part of the hidden pattern imbedded in a print image is included within a reference area set into the print image. In this case, the driver 5 automatically sets the size of the hidden pattern, in response to a size of a print image, whose print is instructed by an application program 4.

Abstract: PURPOSE:To cope with applications, for which the values of optical outputs must be changed frequently, by providing a part, in which a plurality of input data to a D/A converter can be memorized, and providing a part, in which the contents of the memories can be operated. CONSTITUTION:The monitored signal of an optical output, which is detected with a photodiode 2 and a resistor 5, is converted into a digital code in a A/D converter 13. The code is appropriately processed in the operating part (e) and the memory part (f) in a device 14. The result is fed back to the laser diode through a D/A converter 10, a current source 4 and a current switch 6. At this time, the expression of relation between a forward current IF and the optical output PO is assumed to hold, and the constant included in the expression is obtained by operation based on the result of calibrations. The forward current IF for obtaining the arbitrary optical output PO is obtained by an operation. Namely, the values of the optical outputs PO1 and PO2 at points, where calibrations are to be performed, are inputted into the memory part beforehand. The calibrations are performed with reference voltages 1 and 2 corresponding to the values of the respective optical outputs. Thus the optical output having an arbitrary value can be obtained based on the results of the past calibrations.

Title: Dc lighting device for fluorescent lamp
Inventor: O KOKUKA
IPC: H02M3/24
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To easily separate a high tension DC power source and a constant current DC power source by connecting a starter for starting to one end of a filament of a fluorescent lamp in series, and connecting a constant current DC power source through a first diode for reverse blocking and a high tension DC power source through a resistor for keeping high voltage, to the other end in series. SOLUTION: When a fluorescent lamp starter for starting is switched ON, the electric current from a constant current DC power source heats a filament of a fluorescent lamp through a first diode 2 for reverse blocking. On the other hand, as the high tension DC power source has a resistor 4 for keeping high voltage, high voltage can be kept. When the fluorescent lamp starter 1 for starting is switched OFF, the electric current form the high tension DC power source 5 flows in the fluorescent lamp as it is blocked by a second diode 2 for reverse blocking, and high voltage is added to both ends of the fluorescent lamp approximately as it is. As the voltage at both ends of the fluorescent lamp is lowered immediately after the lighting, the electric current from the constant DC power source 3 lights the fluorescent lamp through the first diode 2 for reverse blocking.

Title: Switching power supply device
Inventor: ARIKATA SHINICHIROU
IPC: H02M3/28
Filed: 1979-07-17
Abstract: PURPOSE: To suppress a short circuit current, by controlling and lowering the input voltage when the output voltage is a set value or lower.  
     CONSTITUTION: When a switching power supply 31 is over-loaded and the output voltage is lower than the set value, a constant voltage diode 32 is OFF, the diode current of a photo coupler 25 is reduced, and the transistor 25 of the coupler approaches OFF. Thus, the base current of the transistor 22 starts flowing and the potential of the capacitor 20 is lowered, resulting in increasing the output of an operational amplifier 16. With the increase in the output, the base current of a transistor 12 flows, the base potential of a transistor 10 is lowered toward OFF. A voltage between the collector and the emitter is increased, the input voltage of the switching power supply 31 is lowered, and the current at short-circuit can be suppressed. At the same time, with this constitution, the rush current at the application of power supply is suppressed.
