Abstract:
A fan structure includes a cap, a fixing shaft, a bearing, an impeller and a protection lid, wherein the cap comprises a bottom portion, a body and an accommodating space. The fixing shaft is disposed within the accommodating space, a first end portion of the fixing shaft couples the bottom portion, and a second end portion of the fixing shaft protrudes to the body. The bearing couples to the fixing shaft, the second end portion of the fixing shaft protrudes to the bearing, and a hub of the impeller couples to the bearing. The second end portion of the fixing shaft protrudes to the hub. The protection lid couples to the second end portion of the fixing shaft to prevent lubricants for lubricating the bearing from splashing. The protection lid provides the impeller with protection to prevent the impeller from being compressed by external force to avoid destruction.

A micro-electromechanical (MEMS) switch includes a substrate, stationary actuator comb teeth extending from a stationary actuator pad supported above the substrate, stationary contact comb teeth extending from a stationary contact pad supported above the substrate, and a body suspended over the substrate for rotation about an axis perpendicular to the substrate. The body includes movable actuator comb teeth interdigitated in-plane with the stationary actuator comb teeth where the shortest distance between adjacent movable and stationary actuator comb teeth has a first value. The body further includes movable contact comb teeth interdigitated in-plane with the stationary contact comb teeth where the shortest distance between adjacent movable and stationary contact comb teeth has a second value smaller than the first value.

Abstract:
A magnetoresistive sensor is provided. Specifically, multiple layers of or single layer of conductor line are formed at the same level as an insulating layer on a substrate as a bottom conductive layer. A magnetoresistive structure is formed on the bottom conductive layer and has opposite first surface and second surface. The second surface faces toward the substrate and is contacted with the bottom conductive layer. Afterward, another insulating layer is formed on the first surface, a slot is formed at the same level as the another insulating layer and a conductor line is formed in the slot and contacted with the first surface, so that one layer or multiple layers of conductor line can be formed as a top conductive layer. A lengthwise extending direction of each of the bottom and top conductor layers is intersected a lengthwise extending direction of the magnetoresistive structure with an angle.
Abstract:
In a semiconductor element, and a display pixel and a display panel using the same, the semiconductor element includes a first electrode, a second electrode, an organic light-emitting layer and a third electrode. The second electrode and the first electrode are disposed separately. The organic light-emitting layer is electrically connected with the first electrode and the second electrode. The third electrode is disposed above the organic light-emitting layer.
Abstract:
A class-D audio amplifier is protected by thermal regulation which decreases the gain of the class-D audio amplifier by asserting an over-temperature signal when the temperature of the class-D audio amplifier is detected to be higher than a threshold. The output of the class-D audio amplifier is therefore reduced by the smaller gain, and the chance for the class-D audio amplifier to stop working due to overheating is greatly reduced.
Abstract:
This invention discloses a switching power converter controlled by a winding voltage sampler, including an input circuit with an input end, an output circuit with an output end, one or more switches, a controller to regulate on/off of the switch, a winding voltage sampler, and a transformer including a primary-side coil assembly connecting the switch and the winding voltage sampler, and a secondary-side coil assembly. The output circuit connects the secondary-side coil assembly; the winding voltage sampler detects preset reference voltage of the primary-side coil assembly for the controller to regulate output voltage.
Abstract:
A novel blade assembly for windshield wipers is provided herein. The blade assembly mainly contains a number of tubular segments cascaded in series by a number of connectors. At least a flexible strip is threaded through the series-connected tubular segments to provide even distribution of pressure against the windshield. Each connector has a body for sticking into the two neighboring tubular segments so as to cascade the two tubular segments together. The body of the connectors has at least a through channel for the flexible strip's passing through. The aperture of the through channel decreases from the two ends towards the center of the body, making the blade assembly easier to bend and more conforming to the windshield's curvature.

A sample carrying apparatus capable of revolving a sample includes a body and a revolvable structure. The body has a slot. The revolvable structure partially accommodated within the slot is pivotally connected to the body and is revolvable relative to the body.
Abstract:
A programmable memory built-in self-test circuit and a clock switching circuit thereof are provided. The memory built-in self-test circuit is able to provide more self-test functions preset by a user, simplify the redundant circuit in the prior art and reduce chip area and lower the cost by means of an instruction decoder and a built-in self-test controller. The present invention also provides some peripheral control circuits of a memory. The control circuits occupies less area and enables the memory to be tested more flexibly. The present invention further provides a clock switching circuit enabling a chip to be correctly tested under different clock speeds, which benefits to advance the testability and the analyzability of the memory embedded in a chip and thereby increase fault coverage.
