Abstract: A power converter used in the current control circuit and control method, consisting of a converter, a voltage divider circuit, a current sampling circuit, a first gain circuit, a differential amplifier, a second gain circuit, a multiplier, a saw tooth wave generator, a modulation comparator, and a driver. The invention samples inductor current through the current sampling circuit and generates the current sense signal, then processes again. With the differential amplifier, it compares the feedback voltage from the voltage divider circuit with the reference voltage, and the results along a modulation comparator output a drive signal to control the duty cycle in order to avoid the generation of inrush current. The present invention avoids inrush current caused by the large drive signal and achieves a good response rate and better system stability.

Abstract: A method for repairing a defect, such as a pinhole, on a photomask is described. In an example, a laser beam is used to form a matrix of laser burn spots in a substrate of the photomask proximate a defect, such as a pinhole, of the photomask. Each laser burn spot is formed at a focal point of the laser beam inside the substrate by melting a material of the substrate proximate to the defect. In an example, the defect is surrounded and covered by the matrix of laser burn spots. The matrix of laser burn spots can attenuate or block light from passing through the defect, such as the pinhole. The matrix of laser burn spots may repair the defect of the photomask without removing a pellicle and pellicle frame mounted on the photomask.

Abstract: An electronic device holder is revealed. The electronic device holder includes a base, a top cover and a support member. In use, a control member of the support member is pressed so that a locking shaft is moved inwards to push a shaft part moving into a pivot hole of an assembly block of the base. And a teeth part around the shaft part is released from teeth of a locking hole. Thus the support member can be rotated to the required position. Without any force applied to the control member, the teeth part of the shaft part is engaged with the teeth of the locking hole again due to the elastic member. Thus the support member is locked, the support block is then rotated to the required position and an electronic device is leaning against the support member. Therefore users can use electronics conveniently, without holding them in hands.
