Title: Thermal head driving system
Inventor: KURATA MASAMI
IPC: H04N1/23
Filed: 1983-06-29
Abstract: PURPOSE:To enable to drive a thermal head by a power source with low capacity, by a method wherein a capacitor is charged by providing a rest period of an integer times of a printing cycle period when an electric current for one line exceeds a predetermined value, and white data are supplied to a heat accumulation correcting circuit. CONSTITUTION:A printing dot number counting circuit 4 calculates the black percentage for one printing line, and sets the printing cycle period to be an integer times of the printing cycle period T for a black percentage of 0-25%. When the cycle period T is exceeded, a BUSY signal is outputted, and a black percentage of 0% is inputted as pseudo-printing data, thereby stopping the feed of a paper. A printing pulse generating circuit 6 turns ON and OFF a source driver 7, thereby driving the thermal head and charging a high-capacitance capacitor 9. Accordingly, the number of cycles is not varied with the variation in the driving current depending on the number of printing dots, and by increasing the capacitance of the capacitor and prolonging the printing cycle period, the electric current supplied from the power source can be reduced.

Title: Multiprocessor system
Inventor: KATO SHINYA
IPC: G06F15/167
Filed: 1988-05-13
Abstract: PURPOSE:To access a register in a processor which is small in hardware quality without decreasing memory access efficiency by making an interprocessor communication through registers in processors which are formed by assigning register spaces to banks by the processors. CONSTITUTION:A register R1 (R2 or R3) in one processor P1 (P2 or P3) is assigned to one bank as shown in an assignment example (b), so the hardware quantity is small. Further, the registers R1-R3 in the processors are assigned to one bank, so when the processor P1, for example, accesses the register in the processor P2, other processors P3... can not access the same bank, so the registers in the processors can not be accessed and a bus need not be locked. Further, the bus B is shared for both storage device access and the interprocessor communication, so any dedicated bus for in-processor register access is not required. Consequently, the quantity of hardware is reduced and the efficiency of memory access is improved.
