Abstract: A battery module includes a casing, and a battery assembly, a frequency converting assembly, and a heat dissipation assembly received in the casing. The heat dissipation assembly includes a heat-conducting unit and a heat-dissipating unit. The heat-dissipating unit includes a first dissipation member independent from the battery assembly and the frequency converting assembly. The battery assembly and the frequency converting assembly are coupled to the first dissipation member via the heat-conducting unit to cause heat generated by the battery assembly and the frequency converting assembly to be conducted to the first dissipation member.

Abstract: An on-chip oscillating method which is able to calibrate a frequency of an on-chip oscillator includes: utilizing the on-chip oscillator to generate a predetermined frequency output; receiving an external data input from an off-chip data source; generating a comparison result by comparing the predetermined frequency output with the external data input; and calibrating the predetermined frequency output by utilizing the comparison result. An on-chip oscillating apparatus which is able to calibrate its frequency includes: the on-chip oscillator, arranged to generate a predetermined frequency output; a receiving unit, arranged for receiving an external data input from an off-chip data source; and a comparison unit, arranged for generating a comparison result for calibrating the predetermined frequency output by comparing a predetermined frequency output with an external data input from an off-chip data source.

Abstract: A self-aligned fabrication process for a nozzle plate of an inkjet print head. A substrate is provided with an activated device and a first film is formed on the substrate. Then, a second film is formed on the first film. Next, the second film is defined to form a convex portion corresponding to the activated device, exposing a part of the surface of the first film. Next, a third film is formed on the exposed surface of the first film, covering the convex portion. The third film on the convex portion is then removed. Next, the convex portion and the first film under the convex portion are etched to form a via.
