Abstract: PURPOSE:To decrease the number of signal lines and transistor TR by delivering the contents of a muROM or a PLA to an internal bus with use of a NMOS TR and a PMOS TR having the threshold voltage higher than the 1st power supply voltage as the gates. CONSTITUTION:Power supplies 11a, 12a and 15a are kept at the level of the 1st voltage 5V in a normal working mode. Thus a special output gate 15 is kept at a high impedance when viewed from the side of an internal bus 14. Then the contents of both registers 1 and 2 are delivered to the bus 14 under the control of control signals 4 and 5. When the output of contents is desired with a muROM or a PLA 3, an integrated circuit is reset and therefore both signals 4 and 5 are set at logic 'L'. While the tri-state output buffers 11 and 12 are set under a high impedance state. Therefore, both a NMOS TR and a PMOS TR in the gate 15 are actuated when the power supply 15a is set at a high level. Then the contents of the muROM or the PLA 3 can be read out to the bus 14.

Title: Limiting switching regulator
Inventor: OKINO KAZUMASA
IPC: H02M3/338
Filed: 1990-06-15
Abstract: PURPOSE:To maintain the conversion efficiency high witout enlarging a transformer by limiting the drop of oscillation frequency by the increase of output currents. CONSTITUTION:When the current, which flows in load resistance 22, increases, output voltage drops, and a photo diode 29 ceases to generate an optical signal 24, therefore the on period of a switching element 13 ceases to be shortened. When the switching element 13 is turned off, voltage V52 occurs in the cathode of a diode 52. A delay circuit 54 operates, receiving this voltage V52, and a delay signal 53 is generated. When a transistor 63 is turned on, the on control signal 57 obtained in an on control signal generating circuit 49 is applied to the gate of the switching element 13 through a diode 65, and it turns on the element 13. Hereby, the off period of the switching element 13 is limited to be constant. The on and off periods shorten, respectively, than the case where there is no limitation on the off period, so the drop of oscillation frequency by the increase of load currents can be prevented.
