Title: Prom device
Inventor: ICHIDA KENJI
IPC: G11C16/06
Filed: 1983-03-01
Abstract: PURPOSE:To prevent the increase of power to write in an unselected state even when memory capacity increases by supplying a high voltage for writing to a writing circuit part through plural switching transistors (TR) connected in parallel and controlling the plural switching TRs by an address signal. CONSTITUTION:When the most significant digit bit of an address is at a level 1, a charge pump circuit 8 is operated by a control signal C1 and a charge pump circuit 9 is not operated by a control signal Ctheta. Therefore, Vpp'1 is held at a level Vpp and Vpp'theta is at a level theta. On the other hand, the most significant digit bit of the address is at a level 0, the charge pump circuits operate reversely; and the Vpp'1 is at the level theta and the Vpp'theta is at the level Vpp. Therefore, the Vpp' varies between the levels theta and Vpp according to the most significant digit bit delta, 1 of the address. Namely, the Vpp' in the half area of memory capacity varies between the levels theta and Vpp. Therefore, even when the half area of the memory capacity is in a writing mode, a write current is not conducted to reduce the power consumption for writing.

Title: Driving device of heat-sensing printer
Inventor: YAMAMOTO HARUO
IPC: B41J2/365
Filed: 1983-03-01
Abstract: PURPOSE:To reduce power loss without requiring a control element of large capacity by changing the ratio of on/off of a pulse impressed to a thermal head of a heat-sensing printer. CONSTITUTION:Suppose that the number of gradation of print, e.g., 16 is stored in a 4-bit memory 4 in a heat-sensing printer. A head temperature detecting sensor 6 outputs a voltage (i) in response to the temperature of the thermal head 1 and the voltage (i) is increased or decreased depending on high or low temperature. The level of the voltage (i) is compared with a saw-tooth wave (j) from a sawtooth wave generating circuit 8 in synchronizing with an output (h) of a clock generating circuit 5 at a comparator 9. When the sawtooth wave (j) is larger than the voltage (i), an output signal (k) goes to level ''1'' and when the wave (j) is smaller than the voltage (i), the signal (k) goes to level ''0'' in the comparator 9. The signal (k) and an output (g) of a print signal generating circuit 3 are ANDed by an AND gate 10, an output (l) of the gate 10 becomes a signal pulse-width-modulating a unit time T of the minimum resolution for the gradation print further, thereby eliminating the need for the control element with large capacity.
