Abstract: PURPOSE:To reduce electric current consumed by a readout-only storage device, by connecting an inverter to the gate of a PMOS transistor constituting a ROM cell and the gate of an NMOS transistor and data lines with the drain of one of the two transistors. CONSTITUTION:A P-channel MOS transistor (TR) 1 and N-channel MOS TR 2 constitute a ROM cell. The source of the TR 1 is connected with a high- voltage power source 6 and that of the TR 2 is connected with a low-voltage power source 7. To the gates of the TRs 1 and 2, address signals having different logic levels are inputted by means of the inverter 5. The drain of the TR 1 is not connected with a data line 3, but the drain of the TR 2 is connected with data line 4. Then the lines 3 and 4 are connected with each other and used as a ROM output 13. When an address line 10 is selected, a low voltage becomes the output 13 and, when address line 11 is selected, a high voltage becomes the output 13. Therefore, the electric current consumption of this read only storage device can be reduced and ROM codes can be set during the course of its manufacturing process.

IPC: H02P7/29
Filed: 1984-12-28
Abstract: PURPOSE:To limit a current flowed to a motor irrespective of the gain of an amplifer by turning OFF a PWM signal when a detected current value exceeds a current limit value. CONSTITUTION:A PWM signal generator 4 generates a PWM signals for driving a servo motor so that the position of the shaft of a motor, the difference between the speed and the command value becomes zero. When the current value detected by a current detector 2 exceeds the current limit vlaue of a servo motor 1, the output of a comparator 31 becomes high level.
