Filed: 2005-11-29
Abstract: A DC motor controlling device is provided to protect an FET and a motor against overcurrent resulted from short circuit of a positive or negative terminal of the motor by detecting current at the positive or negative terminal. A gate drive(39) receives a PWM(Pulse Width Modulation) signal through a microcontroller(37), and generates an operation voltage to output it to a gate of an FET(Field Effect Transistor)(31). If the gate drive is input with an overcurrent signal from an overcurrent detecting unit(33), the gate drive interrupts the output of operation voltage to the FET, thereby preventing burn-out of the FET. If a current value detected by a current detecting unit(35) is lower than a predetermined PWM output restricting threshold value, the microcontroller supplies the PWM signal to the gate drive.

Title: Semiconductor storage and mobile electronic device
Inventor: IWATA HIROSHI
IPC: H01L27/115
Filed: 2003-12-19
Abstract: A semiconductor storage has memory function bodies (261, 262) having a function of holding charge and disposed on both sides of a single gate electrode (217) formed over a semiconductor layer (211) with a gate insulating film (214) interposed therebetween. Each memory function body includes a charge holding film (242) having a charge storage region (250). The charge storage region (250) extends over a part of the channel region (273) and a part of one of the diffusion regions (212, 213) formed on both sides of the channel region. Since the memory function bodies are formed on both sides of the gate electrodes independently of the gate insulating film, they can perform two-bit operation. Further, since the memory function bodies are separated from the gate electrode, the interference during rewrite is effectively suppressed and the short-channel effect can be suppressed by reducing the thickness of the gate insulating film. Therefore, microminiaturization of the memory device is facilitated.

Abstract: In a wireless communication system, a method for estimating a transmitted signal is disclosed. A wireless signal is received that includes a pilot channel and at least one other channel. A transmitted signal is estimated using an equalizer and the received wireless signal. The equalizer includes a filter with a plurality of taps that are adapted through use of an adaptive algorithm that uses an estimated pilot estimated from the received wireless signal. The pilot channel is transmitted in the wireless signal that included the at least one other channel. The estimated pilot is extracted and provided to the adaptive algorithm.
