Abstract:
A stepladder has a front frame, a rear frame, a bracket and multiple steps. The front frame has two front side rails and multiple rungs mounted between the front side rails. The rear frame is connected pivotally to the front frame and has two rear side rails, a crossbeam and a lock. The lock is mounted pivotally on the crossbeam. The bracket is connected pivotally and slidably to the rear frame and has multiple pivot pins. The steps are mounted pivotally on the bracket and are selectively and engaged respectively with the rungs of the front frame. The lock selectively hooks a pivot pin to stably lock the bracket for improved safety.

Abstract:
A channel buffering method is for dynamically altering a number of channels for an Internet protocol television (IPTV). The method is applicable for a home gateway (HG) having a channel section used for channel buffering. After the HG has received two consecutive channel-switching requests, the HG compares whether the two requests are similarly directed to switching a channel towards the same direction or not; if yes, a cumulative switching frequency is set, and two trimming numerical values are set through the cumulative switching frequency, and thus, the channel section for buffering the channels can be dynamically adjusted through the two trimming numerical values.
Abstract:
A method of TFT (Thin Film Transistor) manufacturing and a substrate structure are provided. The structure includes a substrate and a self-alignment mask. A self-alignment mask on a substrate is first manufactured and then the self-alignment mask may synchronously extend with the substrate during the thermal process. When an exposure light source is provided on the side without a TFT formed, the self-alignment mask can overcome the problem that when a plastic substrate extends, the positions of the source and drain to be formed on the plastic substrate are incorrect, which has a great effect on the accuracy of alignment. As the result, the positions of the source and drain can be defined accurately.

Abstract:
A method for fabricating a thin film transistor (TFT) display is provided, wherein the processes of a liquid crystal substrate and an organic thin film transistor (OTFT) substrate are separated. The fabrication of liquid crystal substrate employs the technology of polymer encapsulated liquid crystal molecule, and leaves the polymeric layer as a substrate using a sacrificial layer, so as to improve the flexibility. And the TFT substrate has a high adhesive polymeric protective layer provided on its surface, so as to combine the fabricated TFT substrate and the liquid crystal substrate by laminating. Thereby, the processes of the liquid crystal substrate and the TFT substrate will not affect each other, to improve the process yield and meet the demand for the variety of products.
Abstract:
A method, system and computer program product for controlling a processing unit connected to a network. The method includes providing information to the network by the processing unit via plural communication channels; sending a reset signal from a controller to a reset unit of the processing unit after a specified amount of time, the reset unit being connected only to a communication channel of the controller and being isolated from the plural communication channels; and rebooting the processor unit when the reset signal is received by the reset unit.
Abstract:
A steplessly adjustable shoulder rest for violin or the like includes an elongated base having two oppositely spaced recesses provided on an upper surface thereof. Two guiding and locking bolts are separately located at and projected from an outer side of a center of the two recesses to engage with long slots on two adjusting slides, so that the adjusting slides are slidably located in said recesses. Outer ends of the two adjusting slides are two vertical end walls, to outer sides of which two binding elements are screwed to move along with the adjusting slides. Two nuts are tightened to or loosened from the two guiding and locking bolts upward projected from the adjusting slides, so the adjusting slides may be steplessly adjusted to desired positions for the binding elements to best fitly connect the shoulder rest to a lower rear end of the violin or the like.
Abstract:
A method for producing reliable contacts in microelectronic devices and contacts produced thereby are provided. In one embodiment of the invention, a first conductive layer is formed over a first dielectric layer. The first conductive layer contains a pattern etched therein. A second dielectric layer is deposited over the first conductive layer and a via is etched therein over the pattern, thus exposing a portion of the pattern and the first conductive layer. The structure is then further etched to remove a portion of the first dielectric layer using the exposed portions of the first conductive layer as a mask. The structure is then subject to an isotropic etch to create undercuts in the first dielectric layer underneath the exposed portions of the first conductive layer. A conductive material can then be deposited into the via to fill the undercut, thus contacting the first conductive material on the exposed top, sides, and underside of the layer to produce a highly reliable contact. This technique is also adapted to create vias that are used to connect three or more conductive layers.
