摘要： A screw tap with replaceable tool bit has a holding body, a detachable blade, and a fixing element. The holding body has a receiving area and a first engaging portion. The detachable blade is mounted in the receiving area of the holding body and has a second engaging portion, and the second sharp part of the second engaging portion engages with the first sharp part of the first engaging portion. The fixing element is securely mounted through the holding body and the detachable blade. The detachable blade can disassemble from the holding body, and thus one holding body could be installed with detachable blades of various dimensions. As the detachable blade is damaged, the damaged detachable blade is replaced with a new detachable blade to keep processing.

摘要： For applying a driving current to a motor, an H-bridge circuit is constructed by a first and a second switching unit and a first and a second linear unit. An error amplifier generates an error signal representative of a difference between the driving current detected by a current detecting circuit and a command current signal. A state control circuit synchronously controls the first and second switching units and a feedback circuit. Through the feedback circuit, the error signal is selectively applied to the first or second linear unit such that one is operated in a linear mode and the other is operated in a nonconductive mode, thereby controlling the driving current to become proportional to the command current signal. The state control circuit further controls a brake circuit for transforming the error signal into a brake signal to operate the first and second linear units simultaneously in a conductive mode.

摘要： A driving circuit that improves the loading transient performance of a power converter is provided. The driving circuit comprises an input unit, an output unit, a reference current generating unit, and a discharging unit. The input unit receives a first voltage signal and a second voltage signal. The first voltage signal has a first voltage V1 and the second voltage signal has a second voltage V2. The output unit outputs a third voltage signal. The input unit, the output unit, and the reference current generating unit form an error amplifier. A discharging unit has a discharging current path. When V1 is larger than (1+a)*V2, the discharging current path is turned ON. When V1 is smaller than (1+b)*V2, the discharging current path is turned OFF.

摘要： A switching voltage regulator has a first switch, a second switch, and an inductor, which are coupled together to a switch node. A switch control system applies a drive signal for controlling the first and the second switches. A duty cycle detecting circuit detects a duty cycle of the drive signal. When the duty cycle is larger than a predetermined threshold, the duty cycle detecting circuit generates an over-threshold signal. When the duty cycle is smaller than the predetermined threshold, the duty cycle detecting circuit generates an under-threshold signal. In response to the over-threshold signal and the under-threshold signal, an oscillating signal adjusting circuit generates an adjusting current. An oscillating signal generating circuit generates and applies an oscillating signal to the switch control system. The oscillating signal has a period adjusted by the adjusting current.
