Abstract: The present invention proposes an electromotor or generator having an inner stator portion with stator coils and inbuilt switches. The inner stator portion lets an electromotor or generator have KE and KT of different levels in the range of low, middle, or high rotation speed. Variations of KE and KT let the electromotor or generator obtain characteristics of uniform and high efficient operation and “low rotation speed and high torsion” and “high rotation speed and high horsepower”. A maximal hollow inner hole is formed at an inner stator ring portion end. Two end cover plates at the inner ring portion end cover two end faces of the hollow inner hole. The inner ring portion end forms a hollow space after being covered to dispose the switches. The object of the present invention is to resolve complexity and inconvenience of wiring engineering in U.S. patent application Ser. No. 09/848,415: “High Performance Stator Device.

Abstract: A linear regulator capable of sinking current. The linear regulator has an output terminal, providing the next stage with an output voltage. The next stage may feed the linear regulator with current. The linear regulator includes a first transistor, a first amplifier, a second transistor, and a second amplifier. When the output voltage at the output terminal is greater than a certain value, the second transistor conducts and sinks the current from the next stage. The linear regulator according to the invention can handle the problem of the feeding current from the next stage, making the output voltage under the restricted range of the linear regulator.

Abstract: A charge pump circuit 203 boosts a power supply voltage to generate a high voltage VPP in response to clocks CK, CK/ supplied from an oscillation circuit 202. A voltage detecting circuit 205 discriminates whether the high voltage VPP reaches a desired voltage value or not and represents it by discrimination signals LVPP, DIS/. If the high voltage VPP does not reach the desired voltage value, a writing control circuit 201 stops the oscillation circuit 202 from effecting its oscillating operation and stops the charge pump circuit 203 from boosting the power supply voltage to the high voltage VPP in response to the discrimination signal DIS/. Accordingly, the high voltage VPP having a desired voltage value is not applied to a memory cell of a memory circuit 204 so that writing is not effected. Further, the discrimination signal LVPP, is outputted externally so as to represent the writing state in the memory cell.

Abstract: There is provided an input torque detecting device, in power steering, which converts a relative rotation of an input shaft and an output shaft into a movement in a direction of a shaft so as to detect torque. The input shaft 1 and the output shaft 3 are connected via a torsion bar 2 and also a sleeve 7 is installed at a common outer circumference of the input shaft 1 and the output shaft 3. The sleeve is connected to the input shaft 1 through helical splines 8a and 8b which extend in a direction diagonal to a shaft line and connected to the output shaft 3 through straight splines 9a and 9b which extend in a direction of a shaft line, respectively. Torsion of the torsion bar 2 based on input torque is detected as an amount of slide of the sleeve in a direction of a shaft line to be determined by the helical splines 8a and 8b.

The first and second DC voltage controllers generate first and second alternating current (AC) signals having AC voltage components of the buffer input signal reflected thereon, respectively. The first driver drives the voltage level of a buffer output signal to the level of a first voltage, that is, a power supply voltage, in response to the first AC signal. The second driver drives the voltage level of a buffer output signal to the level of a second voltage, that is, a ground voltage, in response to the second AC signal. The first and second AC signals respond to a buffer input signal quickly. The first and the second drivers drive the levels of the buffer output signal to the power supply voltage level and the ground voltage level quickly and by a large amount.
