Inventor: INGORUFU BUROINAA
IPC: G06F21/10
Filed: 1991-07-05
Abstract: PURPOSE: To obtain a method for economically protecting a data medium from its illegal use and illegal copying. CONSTITUTION: A manufacturer registers unit marking 13 in a memory built in data processing peripheral device 11 which can not be accessed by a user. When a data medium is inserted into the device 11 at first, the device 11 wires the same unit marking 13 as that of the device 11 itself in the medium. At the time of using the medium thereafter, the device 11 automatically checks coincidence between its own unit marking 13 and the unit marking 13 of the medium, and at the time of detecting non-coincidence, disables the use of the medium. Thereby the data medium can be used only by the data processing peripheral device 11 having the same unit marking as that of the medium itself.

Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To reduce switching loss by detecting the load state of a load circuit and setting switching period in a PWM control means to a half, when a low load is detected. SOLUTION: When a unit turns into a low-load state, a load current detection circuit detects that a load current has been reduced to a current in a suspend mode or less, and the base current of a control transistor 410 is controlled only by the output signal of a JK flip-flop circuit 440. When a suspend signal circuit 210 sets a suspension signal to a low level, the J input terminal of the JK flip-flop circuit 440 is set to high level, thus setting the output waveform of the JK flip-flop circuit 440 to the pulse of the output rectangular wave voltage of PWM control IC 300, setting the drive frequency of the base current of the control transistor 410 to a half of that of normal operation, and hence also setting the gate input control frequency of a main switching transistor 310 to 1/2.
