Abstract:
A signal generating apparatus, for generating a power-on-reset signal, including a bias circuit and a power-on-reset signal generating circuit is disclosed. The bias circuit is for generating an output bias voltage, and includes at least one bipolar junction transistor (BJT), wherein a base terminal of the BJT is coupled to a collector terminal of the BJT, and the output bias voltage is related to an emitter-to-base voltage of the BJT. The power-on-reset signal generating circuit is coupled to the bias circuit, and is for generating a duplicated voltage by duplicating the output bias voltage, wherein the power-on-reset signal is generated according to the duplicated voltage.
Abstract:
A fan includes a hub rotatable about an axis and having an open end and a closed end, and a plurality of blades extending from the hub. Each of the blades has a leading side surface, a trailing side surface, an inner lateral edge corresponding to the open end of the hub, an outer lateral edge corresponding to the closed end of the hub, and a radial outer edge having opposite inner and outer ends connected respectively to the inner and outer lateral edges, and at least one end portion extending from one of the inner and outer ends toward both the axis and one of the inner and outer lateral edges.
Abstract:
A multi-sub-process cleaning procedure cleans phase shift photomasks and other photomasks and Mo-containing surfaces. In one embodiment, vacuum ultraviolet (VUV) light produced by an Xe2 excimer laser converts oxygen to ozone that is used in a first cleaning operation. The VUV/ozone clean may be followed by a wet SC1 chemical clean and the two-sub-process cleaning procedure reduces phase-shift loss and increases transmission. In another embodiment, the first sub-process may use other means to form a molybdenum oxide on the Mo-containing surface. In another embodiment, the multi-sub-process cleaning operation provides a wet chemical clean such as SC1 or SPM or both, followed by a further chemical or physical treatment such as ozone, baking or electrically ionized water.
Abstract:
A cable installation assembly includes a connector, a power wire, a ground wire and two signal wires. The connector includes a base, having a plurality of terminal containing grooves formed in the base and arranged separately adjacent to each other. The power wire includes a power core and a power terminal electrically coupled to power core, and each power terminal is plugged into each corresponding terminal containing groove. The ground wire includes a grounding core and a grounding terminal electrically coupled to the grounding core and plugged into the terminal containing groove. The signal wire includes a signal core and a signal terminal electrically coupled to signal core, and the two signal terminals are plugged into the terminal containing grooves respectively and not arranged adjacent to each other, so that signals can be transmitted without interfering with one another.
Abstract:
